Wisconsin Mom Found Dead in Her Bed After Husband Poisoned Her with Antifreeze · Murder Files Unsealed

0:00
Speaker 1: Welcome to the deep dive, where we tear apart the
0:02
source material and build you a shortcut to true understanding. Today,
0:07
we are opening a case that sits right at that
0:10
uncomfortable intersection of the perfect American suburban dream and well,
0:14
the darkest kind of betrayal. We're talking about Pleasant Prairie, Wisconsin,
0:18
you know, the kind of community defined by those nice
0:21
two story colonial homes, quiet streets exactly.
0:25
Speaker 2: But within one of those homes, as our sources detail,
0:28
a poison was slowly, methodically being administered.
0:31
Speaker 1: It's a really disturbing picture, it is.
0:33
Speaker 2: We're looking the harrowing story of Julie Jensen, a forty
0:35
year old mother of two. Her sudden death back on
0:38
December third, nineteen ninety eight, kicked off this decades long
0:42
legal odyssey.
0:43
Speaker 1: And the focus of this deep dive. It's really threefold,
0:46
isn't it.
0:46
Speaker 2: Yeah, we want to unpack the insidious nature of chronic
0:49
poisoning itself. Then there's the stunning clarity that came from
0:54
early digital forensics, which is pretty cutting edge stuff for
0:57
the time. And finally, the dramatic on going constitutional battle
1:01
over just one single prophetic document. Julie's final desperate warning.
1:08
People often call it the letter from the grave.
1:11
Speaker 1: So if you're looking to get beyond the headlines and
1:13
really understand the precise details of how justice was eventually
1:18
achieved here, I mean, this is a case where the
1:20
main witness was systematically silenced and.
1:23
Speaker 2: We're fundamental law, you know, the constitution clashed head on
1:27
with the need for accountability.
1:29
Speaker 1: Stick with us. Our mission today is to untack the
1:31
complex science, the digital trail, and the really quite thorny
1:35
jurisprudence that define the Mark Jensen trials.
1:38
Speaker 2: Okay, let's break this down. Start at the beginning, December third,
1:41
nineteen ninety.
1:42
Speaker 1: Eight, right the day it all came crashing down.
1:44
Speaker 2: Mark Jensen, Julie's husband, known figure, ambitious finance guy. He
1:48
calls nine to one to one from their home in
1:49
Pleasant Prairie.
1:50
Speaker 1: Yeah, he reports his wife, Julie is unresponsive, barely breathing,
1:53
he says, in their bed.
1:55
Speaker 2: Paramedics arrive, but well, the scene is grim. She's pronounced
1:58
dead shortly after getting to Kenosha Hospital, and she leaves
2:01
behind two young sons, Douglas who was twelve and David,
2:05
just eight. And that initial phase of the investigation, it's
2:09
really a case study and how the symptoms of this
2:11
kind of insidious poisoning can just perfectly mask a crime.
2:15
Speaker 1: How so, what were the symptoms people were seeing?
2:18
Speaker 2: Well, the sources detail that in the days leading up
2:20
to December third, Julie's health was just rapidly deteriorating. She
2:24
had intense nausea, dizziness, her speech was becoming slurred, and
2:29
she felt this profound, unexplained weakness.
2:33
Speaker 1: And she actually told people she felt weird.
2:34
Speaker 2: Right, Yes, crucially she complained to her family, to friends
2:37
that she felt drugged, that specific word.
2:41
Speaker 1: But because the symptoms were so you know, nonspecific, look
2:44
like a really bad flu, maybe a virus, investigators they
2:47
didn't immediately suspect foul play.
2:50
Speaker 2: Not initially, No, as nineteen ninety eight, remember, the natural
2:53
assumption was some kind of rapid medical crisis, or maybe,
2:57
given that people knew there was stress in the marriage,
2:59
perhaps an attempted suicide.
3:01
Speaker 1: And the first medical findings seemed to back that up.
3:03
Speaker 2: That's right, the Kenosha County Medical examiners, they found no
3:06
obvious external trauma. They ran an initial toxicology screen, standard procedure.
3:11
Speaker 1: And it came back clean clean, which.
3:14
Speaker 2: Essentially supported the narrative of death by natural causes or
3:17
possibly an acute suicide, maybe an overdose of medication she
3:21
was taking. And Mark Jensen, her husband, he strongly advocated
3:26
for that conclusion.
3:27
Speaker 1: Okay, so Mark was actively trying to shape that narrative,
3:31
even telling people it was just a severe virus.
3:33
Speaker 2: Yeah, assuring people it was a virus, which is a
3:36
critical piece when you look at intent, especially considering what
3:39
happened that morning. What happened that morning, Well, he claimed
3:42
he had to leave her alone that morning, had to
3:44
run errands. He said, Yeah, this is while she was
3:46
apparently barely conscious.
3:48
Speaker 1: So that gave him an alibi.
3:49
Speaker 2: Essentially, it ensured that when she finally did succumb, he
3:53
had a plausible reason for his absence, and he had
3:56
already sort of planned the seed of the virus idea
3:59
with people bottom time deniability.
4:01
Speaker 1: But suspicion remained, didn't it, Especially with Julie's family.
4:05
Speaker 2: Oh absolutely, They insisted Julie, despite whatever marital problems they had,
4:10
she was a fighter. She didn't have a history of
4:12
severe depression or self harm. Yes, she was in therapy,
4:16
but they felt she was trying to save herself, her marriage,
4:18
maybe not end her life.
4:20
Speaker 1: And this is where the specific poison comes in and
4:22
how tricky it is to detect initially exactly.
4:26
Speaker 2: This brings us to the expert insight on ethylene glycol poisoning.
4:30
The symptoms Julie showed, the slurred speech, looking almost drunk,
4:34
the nausea. That these are actually hallmark signs of the
4:37
early stages.
4:38
Speaker 1: So why didn't the first tests pick it up well?
4:41
Speaker 2: Two main reasons, especially back in ninety eight. First, investigators
4:44
weren't really expecting poisoning, right, so they weren't specifically testing
4:47
for ethylene glycol or it's metabolized.
4:49
Speaker 1: They were looking for more common things.
4:51
Speaker 2: Right, illicit drugs, maybe high levels of prescription meds. Second,
4:54
the ethylene glycol itself, the parent compound, It actually clears
4:58
the system relatively quickly as the body metabolizes it into
5:01
other toxic stuff.
5:03
Speaker 1: Ah okay, So that initial talk screen just looking for
5:06
the usual suspects, it would easily miss it, especially if
5:10
the levels weren't massive from a single dose.
5:12
Speaker 2: Precisely, especially if it wasn't a single dose. The initial
5:16
clean screens are often the biggest hurdle in prosecuting these
5:21
insidious poisoning cases, if you don't know what poison you're
5:24
looking for, you probably won't find it, particularly.
5:25
Speaker 1: If someone's been given small chronic doses just enough to
5:29
make them sick.
5:30
Speaker 2: Look ill, exactly designed to just make them ill, push
5:34
them closer to a tipping point without raising mediate alarm bells.
5:38
It perfectly allowed that initial conclusion natural causes.
5:43
Speaker 1: So the investigation could have just stalled right there, filed
5:46
away as a tragic medical mystery.
5:48
Speaker 2: It really could have. But investigators, particularly DA Robert John Bois,
5:52
they just had this stubborn instinct something about Mark Jensen's
5:56
behavior didn't sit right.
5:57
Speaker 1: And this is where things take a turn, moving from
5:59
the physical crime scene to the digital one, which is
6:03
pretty new territory back.
6:04
Speaker 2: Then, rand new really in terms of mainstream investigation. They
6:07
seized the family's desktop computer.
6:10
Speaker 1: And that was the breakthrough.
6:11
Speaker 2: Absolutely the breakthrough, and it really highlights how critical digital
6:15
forensics became, even in its early days, for solving these
6:18
premeditated crimes. You know, finding this info in ninety eight
6:22
wasn't like just pulling up your browser history today.
6:24
Speaker 1: No, I imagine it was much harder.
6:26
Speaker 2: They had to dig deep into the hard drive itself.
6:29
And what they found, well, it was basically a chilling
6:33
road map written by the perpetrator himself.
6:36
Speaker 1: It seemed okay detail those searches for us, because the
6:40
sources say they were incredibly specific, suggests real planning.
6:44
Speaker 2: Oh they were investigators uncovered queries made just days before
6:48
Julie died, things like ethylene glycol poisoning, symptoms of anti
6:52
freeze ingestion, just general searches for poisons. Pretty damning already,
6:57
but then it got worse. The truly damning stuff were
6:59
the about avoiding detection, things like undetectable methods of killing
7:04
and even horrifyingly, how to suffocate someone without leaving marks.
7:08
Speaker 1: Wow, it's almost hard to believe he wouldn't realize that
7:11
computer held such incriminating evidence. Was he just naive about
7:15
technology or maybe overconfident?
7:17
Speaker 2: I think the prevailing theory is a mix of both.
7:20
Over confidence, certainly, but also maybe some technological blind spots
7:24
that were pretty common back then.
7:25
Speaker 1: Right. He probably thought deleting the history.
7:28
Speaker 2: Was enough exactly. He likely attempted to clear his browser history,
7:32
maybe deleted some files, but he clearly didn't grasp the
7:35
extent of what forensics Even nineteen ninety eight level forensics
7:38
could recover from the hard drives, residual data, the slack space,
7:43
deleted temporary files.
7:44
Speaker 1: So it wasn't just about what was easy to see, No.
7:47
Speaker 2: Not at all. Retrieving these searches required specific data recovery tools.
7:51
They had to piece together the fragments, the search terms,
7:54
the timestamps. It was about recovering the deleted historical record.
7:58
Speaker 1: Okay, let's focus on the poison itself. For a second,
8:01
ethylene glycol antifreeze. We know it's common, but break down
8:05
how it actually kills someone. Why is it so well
8:08
effective for this kind of calculated murder.
8:10
Speaker 2: Well, you hit on a key reason, accessibility. It's everywhere
8:13
garages stores. It's a clear, sort of syrupy.
8:16
Speaker 1: Liquid, and you can't easily taste it.
8:18
Speaker 2: When it's diluted, it becomes virtually odorless. And here's the
8:22
really insidious part. It has this deceptively sweet taste makes
8:26
it incredibly easy to disguise in things like juice, coffee,
8:31
maybe even soda.
8:32
Speaker 1: So Mark could have been slipping it into her drinks
8:34
over time and she might not have noticed immediately.
8:37
Speaker 2: Precisely, that's the theory of chronic dosing. Once it's ingested,
8:41
the real damage starts as the body tries to process it.
8:44
The initial compound ethylene glycol isn't actually the most lethal
8:48
part itself.
8:49
Speaker 1: It's what the body turns it into right.
8:50
Speaker 2: The liver metabolizes it into a cascade of increasingly toxic acids, glycoaldehyde,
8:56
then glycolic acid, and finally oxalic acid. It's the bill
9:00
up of glycolic acid mainly that causes profound metabolic acidosis.
9:04
The victim's blood literally becomes acidic.
9:06
Speaker 1: That sounds horrific when this leads to the physical evidence
9:09
found later the crystals, Yes.
9:11
Speaker 2: The famous calcium oxalate crystals. The oxalic acid binds with
9:14
calcium in the bloodstream. This forms these sharp, microscopic crystals.
9:17
They get deposited everywhere, but the wreak havoc, primarily on
9:21
the kidneys in the brain.
9:22
Speaker 1: Storing the kidneys, they.
9:23
Speaker 2: Cause catastrophic damage to the renal tubules, leading rapidly to
9:27
acute kidney failure. But even before that, the metabolic chaos
9:31
causes those neurological symptoms we talked about the dizziness. The
9:33
slurred speech makes the person look drunk or like they're
9:37
having a stroke.
9:37
Speaker 1: So after the computer evidence pointed directly to anti freeze,
9:40
they ran more tests.
9:41
Speaker 2: Exactly, a second, more specific toxicology screen was performed, and
9:47
this time they can from traces of ethylene glycol and critically,
9:51
the autopsy revealed those telltale calcium oxalate crystals embedded in
9:55
Julie's kidneys.
9:57
Speaker 1: And the pattern of poisoning was important too, rite not
9:59
just the presence of.
10:00
Speaker 2: It, hugely important. The forensic confirmation wasn't just that she
10:03
was poisoned, but how. The specific mix of metabolites found
10:07
suggested repeated low level exposure over days, maybe even weeks,
10:11
not a single massive.
10:13
Speaker 1: Dose, which argues against suicide.
10:15
Speaker 2: Strongly argues against it. A suicide attempt would generally involve
10:19
swallowing a large amount all at once acute ingestion. This
10:23
chronic dosing pattern pointed towards a calculated, methodical effort to
10:27
push her body towards failure, all while making it look
10:30
like she was just getting sicker and sicker from some illness.
10:33
Speaker 1: And this ties back to that chilling digital timeline. Again,
10:36
you mentioned a specific search interest.
10:38
Speaker 2: Prosecutor Angelina Gabriel later highlighted this. This specific search for
10:43
diminished consciousness from ethelene glycol It occurred at nine forty
10:47
two am on December third, the very morning Julie died.
10:52
Speaker 1: Just after he supposedly got back from his errands.
10:54
Speaker 2: Precisely. The timing is critical. It's a Jesse returned home,
10:58
checked on his wife, saw her failing state, that diminished
11:01
conscioupence he'd just searched for, and was straight to the computer,
11:04
not to call for help, but to check the prognosis
11:06
based on the poison you'd already administered.
11:09
Speaker 1: That's incredibly powerful, circumstantial evidence linking his knowledge directly to
11:13
her final moments.
11:14
Speaker 2: It became a cornerstone of the prosecution's case regarding his intent.
11:17
Speaker 1: Okay, so we have the science, the digital trail, but
11:21
to really grasp Julie's fear, the fear that led her
11:24
to write that letter, we need to step back and
11:27
look at the marriage itself. Right.
11:29
Speaker 2: Context is everything here. Julie Carrol Griffin married Mark Jensen
11:32
back in nineteen eighty four. On the surface, you know,
11:35
typical suburban couple raising their two boys. Mark had that
11:39
high profile finance.
11:40
Speaker 1: Job, living the dreams supposedly.
11:42
Speaker 2: Fade the facade, Yes, but our sources detailed that this
11:47
harmony was well, it was largely a facade, and it
11:50
had started cracking years earlier.
11:51
Speaker 1: What was the main issue.
11:53
Speaker 2: The source material focuses pretty heavily on a brief affair
11:55
Julie had with a coworker back in nineteen ninety one.
11:58
Now what's really telling here is Mark's reaction.
12:01
Speaker 1: He couldn't let it go.
12:02
Speaker 2: He never truly forgave her. The resentment just festered, became
12:05
more than just about infidelity. It seems it morphed into
12:08
this control mechanism for him, a source of deep, long
12:12
term detachment on his part.
12:13
Speaker 1: So it wasn't a marriage that healed. It sounds more
12:15
like a slow emotional poisoning almost that came before the
12:19
physical one.
12:19
Speaker 2: That's a chilling way to put it. But Yeah, by
12:22
late nineteen ninety eight, the situation was dire. Julie was
12:25
in therapy, feeling isolated, trapped, and she was becoming increasingly
12:30
aware of a potential danger.
12:32
Speaker 1: She confided in people she did.
12:34
Speaker 2: She told her brother Larry Griffin that Mark was exhibiting
12:37
genuinely disturbing behavior. She used phrases like he was acting
12:41
strange and significantly trying to make me look crazy.
12:44
Speaker 1: Trying to make me look crazy, That phrase jumps out.
12:46
It sounds like gaslighting.
12:48
Speaker 2: Textbook, and that leads directly to the infamous list. In
12:52
November nineteen ninety eight, just weeks before her death, Julie
12:55
found this handwritten list tucked away in Mark's business planner.
12:59
Speaker 1: Not just a groy list, I take it, No, not
13:01
at all.
13:02
Speaker 2: This was Mark's meticulous, almost clinical record of Julie's perceived failings,
13:06
things like forgetting appointments, snapping at the kids, other instances
13:10
of what he framed as erratic behavior.
13:12
Speaker 1: In julie interpretation of this list, it wasn't just that
13:15
he was annoyed with her.
13:16
Speaker 2: No, her interpretation was chillingly accurate and frankly terrifying. She
13:21
saw it not as just a list of complaints between spouses.
13:24
She saw it as deliberate premeditation, a blueprint exactly, a
13:27
blueprint designed to be discovered after her death, or maybe
13:31
shown to police or social services beforehand, to establish her
13:34
as unstable erratic. If she died suddenly, he wanted documentation
13:39
readily available to paint it as a suicide, or at
13:41
least something linked to her own supposed instability.
13:44
Speaker 1: That level of psychological manipulation is.
13:46
Speaker 2: Just wow, designed to completely neutralize her credibility before he
13:50
even acted.
13:50
Speaker 1: It's calculated gaslighting. And it was finding this list, combined
13:55
with her own physical symptoms, the grogginess, maybe noticing drinks
13:58
tasting oddly sweet, that fueled this profound, paralyzing fear.
14:03
Speaker 2: Which led her to take this extraordinary step, the step
14:06
that would echo through the courts for decades.
14:09
Speaker 1: She created her dying declaration, a letter.
14:12
Speaker 2: This is really the emotional core of the whole case,
14:15
isn't it.
14:15
Speaker 1: Absolutely On the morning of November twenty first, nineteen ninety eight,
14:19
it was early seven am, Julie sat down with yellow
14:22
legal paper and wrote this letter. She addressed it specifically
14:25
to whomever finds this sometimes reported as to.
14:28
Speaker 2: Law enforcement, and she was very careful about how she
14:30
prepared it, extremely careful. She sealed it in an envelope,
14:34
and crucially, she included a photograph she'd taken of Mark's
14:38
incriminating list inside that envelope, proof positive of the source
14:42
of her fear.
14:43
Speaker 1: Do we know what the letter actually said? The sources
14:45
quote parts of it.
14:46
Speaker 2: Yes, the key lines are haunting. She wrote something like,
14:50
I took this picture of the list and am writing
14:52
this on Saturday, eleven, twenty one, ninety eight at seven am.
14:56
This list was in my husband's business daily planner. Not
15:00
meant for me to see. I don't know what it means,
15:02
but if anything happens to me, he would be my
15:04
first suspect.
15:05
Speaker 1: And she explicitly mentioned fear for her life.
15:08
Speaker 2: She did. She added words to the effect of I
15:10
pray I'm wrong, plus nothing happens, but I am suspicious
15:13
of Mark's suspicious behaviors, plus fear for my early demise.
15:17
I fear for my life and apparently my husband has
15:20
talked about killing me and getting away with it. Though
15:22
the exact phrasing very.
15:24
Speaker 1: Slightly in reports, and what she did with a letter
15:26
is just as telling is what she wrote.
15:27
Speaker 2: Absolutely, she didn't just hide it. She immediately drove the
15:30
sealed letter over to her neighbors, the Hoofs. They were
15:33
a trusted retired couple, and.
15:35
Speaker 1: She gave them specific instructions.
15:37
Speaker 2: She begged them, basically, don't open this unless something happens
15:41
to me. She wasn't just scribbling a worried note. She
15:45
was deliberately establishing an airtight contingency plan in case of
15:49
her own murder. She knew, she understood with terrifying clarity,
15:54
what he was potentially planning.
15:56
Speaker 1: And just two weeks later.
15:57
Speaker 2: Tragically, yes, just two weeks later, the Hoofs found themselves
16:01
handing that sealed prophetic envelope over to the Kenosha police.
16:05
Speaker 1: Okay, so Julie dies into summer ninety eight. Mark Jensen
16:08
isn't arrested immediately though.
16:10
Speaker 2: No, it took time. The investigation was complex, especially piecing
16:13
together the digital evidence and the toxicology. He was eventually
16:17
arrested in two thousand and three. About four years later.
16:19
Speaker 1: And the first trial that was in two thousand and eight.
16:21
Speaker 2: It got a lot of attention, massive national media attention.
16:24
It was moved out of Kenosha County to Walworth County
16:26
due to pre trial publicity. The prosecution laid out a
16:30
robust case.
16:31
Speaker 1: What was the key evidence they presented?
16:33
Speaker 2: Well, you had the chilling computer searches obviously, you had
16:36
the toxicologist testimony explaining the chronic dosing, how it built
16:40
up to a tipping point. And then the heartbreaking testimony
16:42
from the suns Douglas.
16:44
Speaker 1: And David, And there was an informant too.
16:47
Speaker 2: Yes, they also used a jailhouse informant, a man named
16:50
John Dillard. He claimed Mark Hat confessed to him while
16:54
they were incarcerated together, supposedly saying something like I poisoned
16:58
her with antifreeze.
17:00
Speaker 1: But the real bombshell, the emotional centerpiece, was Julie's.
17:03
Speaker 2: Letter, without a doubt. But getting that letter admitted into
17:07
evidence wasn't straightforward. It required a specific legal maneuver.
17:11
Speaker 1: Because it's hearsay right and out of court statement.
17:13
Speaker 2: Exactly hearsay is generally inadmissible. The prosecution argued it should
17:18
come in under what was then known as a residual
17:20
hearsay exception.
17:22
Speaker 1: Okay for listeners maybe not familiar with legal jargon, what
17:25
does that exception mean?
17:27
Speaker 2: Basically, well, it was kind of a catch all exception.
17:31
It existed for statements that didn't fit neatly into other
17:34
standard hearsay exceptions, like a formal dying declaration made right
17:38
before death or statement of present sense impression. But critically,
17:42
the statement had to have strong guarantees of trustworthiness and
17:46
be really necessary for the court to find the truth.
17:48
Speaker 1: So they argued Julie's letter met those criteria.
17:52
Speaker 2: They successfully argued that because Julie obviously couldn't testify herself.
17:56
This unique document detailing her specific fear and pointing to
18:00
her husband, written when she clearly felt in danger, was
18:04
highly trustworthy and essential to proving motive and intent.
18:07
Speaker 1: And the judge agreed. The jury heard the letter, yes.
18:10
Speaker 2: And that strategy worked. The jury found Mark guilty in
18:13
March two thousand and eight first degree intentional homicide. He
18:16
got life without parole.
18:17
Speaker 1: But the defense immediately appealed, and their argument centered squarely
18:21
on that letter.
18:22
Speaker 2: Absolutely, this is where the case shifts from just a
18:24
horrific crime story into this profound constitutional flashpoint. The defense
18:29
argue that admitting the letter violated Mark Jensen's sixth Amendment rights.
18:33
Speaker 1: The right to confront your accuser.
18:35
Speaker 2: Exactly. The sixth Amendment guarantees a criminal defendant the right
18:39
to be confronted with the witnesses against him. It's a
18:42
cornerstone of the US legal system. The defense argued that Julie,
18:47
through her letter, was essentially acting as a witness against Mark,
18:50
and he.
18:50
Speaker 1: Had no chance to cross examine her statement.
18:52
Speaker 2: Obviously none whatsoever. Dead witnesses can't be cross examined. This
18:57
argument wasn't entirely new, but it gained enormous traction in
19:01
the mid two thousands because of a landmark Supreme Court case.
19:04
Speaker 1: You're talking about Crawford vw Washington.
19:06
Speaker 2: Precisely, the defense heavily leveraged the Crawford decision from two
19:10
thousand and four. Crawford radically redefined the confrontation clause. It
19:14
essentially said that testimonial out of court statements cannot be
19:18
admitted unless the witness is available to testify and the
19:22
defendant had a prior opportunity to cross examine them.
19:24
Speaker 1: Okay, So what makes a statement testimonial? That seems key?
19:27
Speaker 2: That became the core question. Generally, testimonial statements are those
19:32
made with the primary purpose of creating an out of
19:35
court substitute for trial testimony. Think statements made during a
19:38
police interrogation, or affidavits or arguably a dying declaration like Julie's,
19:43
written specifically to law enforcement or whomever finds this in
19:48
anticipation of a future investigation.
19:50
Speaker 1: So the courts had to decide, was Julie's letter, written
19:53
anticipating her death and naming Mark as the suspect testimonial under.
19:58
Speaker 2: Crawford, and the federal courts ultimately said yes. It was.
20:01
They reasoned that because Julie wrote the note specifically anticipating
20:05
its potential use in a future prosecution, essentially creating evidence
20:09
for law enforcement, it met the Crawford definition of testimonial.
20:12
Speaker 1: Meaning admitting it violated Mark's rights.
20:15
Speaker 2: Correct Convicting Mark based partly on that statement without any
20:18
possibility of cross examination was deemed a violation of his
20:21
fundamental constitutional right to confrontation. So in twenty thirteen, a
20:25
federal court overturned the conviction, and the Seventh Circuit Court
20:28
of Appeals upheld that reversal in twenty fifteen.
20:30
Speaker 1: That must have been just devastating for the prosecution. For
20:33
Julie's family, facing the possibility of him being released or
20:37
at minimum having to retry the entire case without their
20:40
strongest piece of evidence.
20:41
Speaker 2: It was a huge blow, a genuine constitutional crisis for
20:45
the state of Wisconsin. The case worked its way up
20:48
to the Wisconsin Supreme Court, and this led to a
20:51
really crucial and divided four to three decision in July
20:55
twenty twenty one, and.
20:57
Speaker 1: The majority sided with the federal courts. They ordered or
21:00
retrial without the letter.
21:01
Speaker 2: They did. The majority, led by then Chief Justice Patients
21:05
Rogensack held firm to that strict interpretation of Crawford and
21:09
the confrontation clause.
21:10
Speaker 1: What was their reasoning, How did they justify excluding such
21:13
powerful evidence.
21:15
Speaker 2: Their opinion essentially boiled down to this, while the outcome
21:18
feels wrong, feels tragic, the legal process itself must be
21:22
protected above all else. They concluded that admitting the letter,
21:25
no matter how prophetic or seemingly trustworthy, it was risked
21:29
undermining the entire system's commitment to the right of confrontation.
21:32
Speaker 1: And Justice Rogensack had that memorable line.
21:34
Speaker 2: Yes, the source material highlights it, the voice of the
21:38
dead must yield to constitutional safeguards. It's a stark affirmation that,
21:44
in their view, the constitutional process trumped even the most
21:48
emotionally compelling piece of evidence.
21:50
Speaker 1: But it was a split decision four to three. The
21:52
dissenting justices must have strongly disagreed.
21:55
Speaker 2: Oh absolutely. The dissent, led by Justice Ann Walsh Bradley,
21:59
argued passionately against excluding the letter. They raised the concept
22:03
of forfeiture by wrongdoing, meaning they argued that Mark Jensen,
22:07
by allegedly murdering Julie, had forfeited his right to confront her.
22:12
He was the reason she couldn't testify. They felt the
22:14
Crawford rules shouldn't apply so rigidly when the defendant themselves
22:18
caused the witnesses unavailability, they.
22:20
Speaker 1: Saw it as letting him benefit from his own crime.
22:22
Speaker 2: Essentially. Yes, they also argue Julie's letter was written primarily
22:25
out of desperate fear and a plea for self preservation,
22:28
not purely to build a legal case, and that excluding
22:31
it completely silenced her voice in a way that felt
22:34
like a miscarriage of justice.
22:35
Speaker 1: But the majority opinion held. The end result was a
22:38
retrial ordered to proceed without the letter exactly.
22:42
Speaker 2: The confrontation clause prevailed, and the prosecution faced the monumental
22:46
task of rebuilding their entire case, this time relying solely
22:50
on evidence that wasn't considered testimonial.
22:53
Speaker 1: Okay, So fast forward to January twenty twenty three. Mark Jensen,
22:57
now sixty three, is back in court for his second trial, and.
23:00
Speaker 2: As defense team led by Craig Alby this time, they're
23:03
clearly banking on the fact that the state can't use
23:05
that incredibly powerful letter, so.
23:07
Speaker 1: They pivot hard to the suicide defense.
23:09
Speaker 2: Exactly. They really hammered on Julie's known history of taking antidepressants,
23:14
the documented marital stress, the past affair. Their narrative was
23:18
that she was depressed, maybe unstable, and tragically decided to
23:22
end her life, perhaps framing Mark out of spite.
23:24
Speaker 1: So the challenge for the prosecution, led again by Angelina
23:27
and Gabrielle, was enormous. They'd lost their emotional anger.
23:30
Speaker 2: Immense That letter established motive and fear almost instantly with
23:34
the first jury. Now they had to pivot completely away
23:37
from that powerful emotional narrative. They had to rely, as
23:40
you said earlier, entirely on the clinical.
23:42
Speaker 1: Facts, forensics, timestamps, patterns of behavior exactly.
23:46
Speaker 2: And the absolute centerpiece of that new strategy was the
23:49
digital evidence. They had to make the second jury understand
23:52
that those computer searches were, in effect the substitute for
23:56
Julie's own voice, warning.
23:57
Speaker 1: Them, how do they approach that.
23:59
Speaker 2: They just hammered that digital footprint relentlessly. They detailed again
24:04
those twenty plus poison related searches Mark made in November
24:07
nineteen ninety eight. They meticulously showed the jury how the
24:11
search is correlated directly with the specific type of poisoning
24:14
July suffered.
24:15
Speaker 1: From, showing premeditation.
24:17
Speaker 2: Demonstrating a level of planning and research completely inconsistent with
24:20
the defense's suicide theory. Prosecutor Gabrielle's closing argument was reportedly
24:26
very effective. She posed that rhetorical question to the jury,
24:29
something like who researches their own wife's symptoms that they're innocent?
24:33
An innocent man calls a doctor a guilty man researches
24:36
how to kill without getting caught.
24:38
Speaker 1: Powerful. And they also brought back witnesses to testify about
24:40
Mark's behavior right to fill that narrative gap left by
24:43
the letter absolutely vital.
24:45
Speaker 2: They needed to paint a picture of his mindset and actions.
24:49
Ed Klugg, Mark's former co worker, returned to the stand.
24:53
His testimony was crucial.
24:54
Speaker 1: Again why Plug's testimony, specifically because it.
24:57
Speaker 2: Showed Mark's morbid fascination with poison wa wasn't just a
25:00
sudden impulse linked to the time of death. Glood testified
25:04
about conversations back in nineteen ninety eight at conferences where
25:07
Mark had apparently quite casually joked about offing Julie. He
25:12
talked about Mark looking up poisoned websites even then.
25:14
Speaker 1: And he quoted Mark saying something chilling.
25:17
Speaker 2: Yeah. The quote that really stood out, According to Sourzes,
25:19
was Mark telling Clug something like if I ever wanted
25:22
to kill her, no one would know. That speaks volumes
25:25
about premeditation stretching back potentially years, a cold, calculating mindset,
25:30
and the suns.
25:31
Speaker 1: They testified again. They were adults now.
25:34
Speaker 2: Yes, Douglas and David now men in their thirties. It
25:37
must have been incredibly difficult, but their testimony was powerful
25:41
for the jury. They returned to the stand, forced to
25:44
relive the final agonizing hours of their mother's life.
25:47
Speaker 1: What did they focus on?
25:48
Speaker 2: They testified about Mark's extreme callousness, his detachment, his constant
25:53
weight and see attitude, while Julie was obviously suffering terribly
25:57
from something much worse than the flu he claimed it was.
26:01
Douglas specifically recounted begging his father to call an.
26:04
Speaker 1: Ambulance a plea refused, refused.
26:08
Speaker 2: This testimony directly countered the defense's attempt to portray Mark
26:12
as just a worried husband, maybe making poor choices under stress.
26:16
It pointed towards a deliberate intent to let her die.
26:19
Speaker 1: So how did the defense's suicide theory, the antidepressants, the
26:23
stress hold up against this wall? Of forensic and behavioral
26:26
evidence in the second trial, Well, this is.
26:28
Speaker 2: Where the scientific certainty really became the deciding factor, especially
26:31
without the letter tilting the scales emotionally. The defense needed
26:34
the jury to believe in an acute, single dose ingestion
26:38
consistent with suicide.
26:39
Speaker 1: But the science didn't support that.
26:40
Speaker 2: The forensic toxicologists were unwavering. They testified again that Julie's
26:45
blood the metabolites found were consistent only with repeated dosing
26:49
over a significant period, chronic poisoning. That pattern is scientifically
26:55
inconsistent with a typical single, massive suicidal overdose.
27:00
Speaker 1: No evidence she researched poisons herself.
27:02
Speaker 2: Crucially, no evidence ever emerged that Julie herself had accessed
27:06
Andy Freeze, researched it, or looked into any methods of
27:09
self harm involving toxins. The digital trail pointed solely at Mark.
27:13
Speaker 1: So it was that combination the undeniable digital premeditation, the
27:18
witness accounts of his indifference and morbid comments, and the
27:21
definitive scientific evidence of chronic dosing that finally overcame the
27:25
loss of the letter.
27:26
Speaker 2: It seems so after about eleven hours of deliberation, the
27:29
second jury reached the same conclusion as the first. The
27:32
convicted Mark Jensen again on January thirty first, twenty twenty.
27:35
Speaker 1: Three, just secured, but this time built purely on a
27:38
foundation of scientific and circumstantial evidence that meticulously adhere to
27:42
those strict constitutional.
27:43
Speaker 2: Rules exactly, and at the sentencing a few weeks later,
27:47
February twenty fourth, Judge Anthony Millisaskas sentenced Mark again to
27:51
life without parole. His final words to Jensen, as recorded
27:56
in the source material, were incredibly potent.
27:58
Speaker 1: What did he say?
27:59
Speaker 2: He told old Mark Jensen, you poison not just her body,
28:03
but her trust. A chilling summary of the profound betrayal. Mark,
28:07
apparently unrepentant, appealed again. But this second conviction, built on
28:11
this painstakingly constructed, forensic and circumstantial case, has held firm.
28:16
Speaker 1: Julie Jensen's story is just horrific. But sadly, as you
28:19
dig into the source matery, you realize it's not entirely
28:21
unique anti freeze ethylene glycol. It seems to be a
28:24
disturbingly common weapon, particularly in domestic homicides.
28:27
Speaker 2: Yeah, it speaks to a wider, darker pattern when you
28:30
analyze these cases. The appeal of this specific poison in
28:34
intimate partner violence becomes clear. They're often labeled, sometimes sensationally,
28:38
as black widow cases.
28:39
Speaker 1: The sources mention other examples they do.
28:42
Speaker 2: Stacy Caster, for instance, in New York, she killed two
28:45
husbands with any freeze back in two thousand and five
28:47
and meticulously staged one of the deaths to look like suicide.
28:51
Then there's the case of Diane Stout in Missouri between
28:55
twenty twelve and twenty thirteen. She poisoned her husband, her son,
28:58
and even attempted to pour and her daughter with Andy Freese.
29:01
What was her motive, she confessed It was simply hatred
29:04
for her family members, just chillingly cold.
29:07
Speaker 1: So for someone contemplating this kind of crime, the chemical
29:09
properties easily available, sweet taste mimics illness. It creates this
29:14
sort of perfect storm of deniability that.
29:17
Speaker 2: Seems to be the thinking. Doctor Bruce Goldberger, a toxicologist
29:20
cited in the materials, really emphasized this ethylene glycol's appeal
29:24
lies in that accessibility everywhere garages, stores, and the way
29:28
its symptoms create an easy cover story. The killer can
29:31
play the role of the concerned spouse watching the victim decline,
29:35
while attributing it all to stress, the flu, maybe mental instability.
29:39
Speaker 1: The Gensen case itself, though, did it lead to any changes,
29:41
any positive legacy in terms of prevention, Yes.
29:44
Speaker 2: It did contribute to significant legislative reform. The horrific nature
29:49
of Julie's death, coupled with the intense media spotlight on
29:52
the trials, really raised public awareness and put pressure on.
29:56
Speaker 1: Lawmakers, specifically regarding anti free exactly.
29:59
Speaker 2: It led to mandates in many states requiring manufacturers to
30:03
add a bittering agent to antifreeze to make it taste
30:06
awful severely unappetizing. Yes, it's primarily a public health measure
30:11
aimed at preventing accidental poisonings, especially in children and pets
30:15
who might be attracted by the sweetness, but it also
30:18
acts as a deterrent against intentional ingestion. A determined killer
30:22
might still try to mask the taste, but the law
30:25
recognized the inherent danger posed by its original palatability.
30:28
Speaker 1: And what about the family, Julie's sons, her brother. It's
30:31
been such a long ordeal for them.
30:33
Speaker 2: The sources indicate they finally found some sense of resolution
30:36
with the second conviction, holding the sons Douglas and David
30:40
now grown men, one in finance, the other in education.
30:43
They were raised by Julie's devoted sister and brother in law.
30:46
After her death.
30:47
Speaker 1: Are they in contact with their father?
30:48
Speaker 2: Understandably no, They remain estranged. And Julie's brother, Larry Griffin,
30:54
he became a strong advocate using Julie's story to raise
30:57
awareness about domestic violence, trying to sure her memory serves
31:01
a wider purpose.
31:02
Speaker 1: And that really speaks to the enduring impact of Julie's actions,
31:05
doesn't it. Even her letter, though ultimately barred from the second.
31:08
Speaker 2: Trial, its influence was profound. It absolutely directed the initial
31:12
investigation toward homicide when it might otherwise have been dismissed
31:15
as suicide or natural causes. It undoubtedly strengthened the prosecution's
31:20
resolve through all the appeals and setbacks, and it forced
31:24
them ultimately to build that rock solid non testimonial case
31:28
that finally secured justice.
31:29
Speaker 1: So, even when silenced by the strict interpretation of sixth
31:32
Amendment in.
31:33
Speaker 2: Court, her voice still shaped the entire projectory of the case.
31:36
It's a testament to her foresight and courage in that
31:39
moment of.
31:39
Speaker 1: Extreme fear, there's a memorial garden mentioned in the sources
31:42
in Pleasant Prairie, Yes.
31:44
Speaker 2: Near the lake, apparently a quiet place in her honor,
31:47
and the inscription reads for Julie Love and Door's justice prevails.
31:52
It kind of underscores the sheer perseverance it took from
31:55
everyone involved, investigator's prosecutors, her family to navigate the immense life, legal,
32:00
and scientific complexities of this case over two decades. Hashtag outro.
32:05
Speaker 1: Wow, this has been a really deep dive into a
32:07
case that truly pushed the legal system to its limits.
32:11
Let's just quickly recap the two essential learnings you can
32:14
really take away from the source material we've broken down today.
32:17
Speaker 2: Yeah. I think the first is just the incredible sophistication
32:20
and frankly, the foresight required to use that early digital
32:23
forensics evidence, that chilling browser history from nineteen ninety eight
32:26
to successfully prove a case of insidious chronic poisoning, poisoning
32:30
that was deliberately designed to mimic a natural death right.
32:33
Speaker 1: And the second key takeaway has to be that intricate,
32:36
almost agonizing constitutional tension we saw play out.
32:39
Speaker 2: Absolutely, we watched this fundamental conflict unfold between on one hand,
32:45
the raw emotional power of a victim's final warning, that
32:49
innate human desire to listen to Julie's prophetic plea, and
32:52
on the other hand, the absolute legal necessity of upholding
32:55
those constitutional safeguards, specifically the sixth Amendment right to confront
33:00
your accuser.
33:00
Speaker 1: It really shows that even when guilt seems incredibly clear,
33:04
the process, the constitutional rules, they still have to be
33:07
followed meticulously.
33:09
Speaker 2: Exactly the system demands it.
33:11
Speaker 1: You know, the source material mentions that Julie's brother felt
33:13
she saved us by speaking out, meaning her sons, And
33:16
this whole case serves as the stark reminder, doesn't it
33:19
that the greatest danger sometimes doesn't come from strangers, but
33:22
from within the most intimate relationships, the ones built on trust.
33:26
Speaker 2: Mark Jensen didn't just poison Julie's body, He poisoned the
33:29
very core of family trust, community.
33:31
Speaker 1: Trust, which raises a final, maybe provocative thought for you,
33:35
our listeners, to consider.
33:37
Speaker 2: Julie Jensen was incredibly proactive in documenting her fear. She
33:41
wrote the letter, she saved, the list, she spoke to
33:43
her brother. We have to ask ourselves, does our current
33:47
legal system, particularly with its strict adherence to the confrontation clause,
33:51
as interpreted by Crawford, provide an adequate or rapid enough
33:55
mechanism for self preservation for victims who anticipate danger in
33:59
intimate partner or violence when the act hasn't happened yet,
34:02
but the fear and the documentation are there.
34:05
Speaker 1: Yeah, how does the legal system effectively balance the accused
34:08
fundamental rights with a potential victim's desperate attempts at self preservation,
34:13
especially when their documented fear might be their only shield
34:16
that tension.
34:17
Speaker 2: That's a critical ongoing challenge within the justice system today,
34:20
something we're thinking about.
34:21
Speaker 1: A profound thought. Indeed, I'm all that over until our
34:24
next deep dive. Thanks for listening.
