Transcript
- 0:00Speaker 1: What's up everyone, and welcome back to the program. In
- 0:03Speaker 1: this episode, we're diving right back in discussing the experts
- 0:07Speaker 1: behind the case against Brian Colberger. Amended supplemental expert disclosure
- 0:13Speaker 1: Tara Martinez. The State has previously disclosed Tara Martinez Forensic
- 0:18Speaker 1: Scientists three as an expert witness in the field of
- 0:21Speaker 1: forensic science, which includes, but no way is limited to
- 0:25Speaker 1: latent prints and bugle swab collection and scene processing. The
- 0:29Speaker 1: State hereby incorporates its previous response and attachments filed on
- 0:33Speaker 1: December eighteenth, twenty twenty four, and is hereby supplementing its
- 0:37Speaker 1: response as follows. Martinez can be expected to testify regarding
- 0:42Speaker 1: her involvement in this case, specifically when obtaining a bugle
- 0:46Speaker 1: swab from Brian Colberger in January of twenty twenty three.
- 0:50Speaker 1: Martinez also collected hair samples and finger prints from Brian Colberger.
- 0:55Speaker 1: Further description of this can be found in Hailey Jungling's
- 0:58Speaker 1: report twenty one bates pages six four one four through
- 1:02Speaker 1: six four to two two. Martinez will explain the process
- 1:06Speaker 1: of collecting bugle swabs and the purpose of collection. Bucle
- 1:10Speaker 1: cells are found on the inside of a person's cheek.
- 1:13Speaker 1: A sterile cotton swab or a para swabs is used
- 1:16Speaker 1: to collect these cells as a reference DNA sample from
- 1:19Speaker 1: a known individual. Buckle swab samples can be compared to
- 1:23Speaker 1: unknown DNA samples from a crime scene or from an
- 1:27Speaker 1: item of evidence. Martinez may discuss what latent prints are
- 1:32Speaker 1: and why they're important in a forensic setting or investigation.
- 1:36Speaker 1: Latent prints or impressions or a friction ridge skin patterns
- 1:40Speaker 1: that can be left on a surface when contact is made.
- 1:43Speaker 1: The term latent refers to prints that are not visible
- 1:46Speaker 1: prior to utilizing a development method. Latent prints are often
- 1:50Speaker 1: made up of various matrices, including sweat and oils, that
- 1:55Speaker 1: are a colorless and require development with chemicals or powders
- 1:59Speaker 1: to be seen. Prints at a crime scene may also
- 2:02Speaker 1: be made from other materials that may coat the skin,
- 2:06Speaker 1: like blood or dirt. Although latent means hidden, any prints
- 2:10Speaker 1: recovered from a crime scene or from items of evidence
- 2:13Speaker 1: are often referred to as latent prints. Latent prints processing
- 2:17Speaker 1: methods are different at a crime scene versus in a laboratory.
- 2:21Speaker 1: The method for latent print processing at a crime scene
- 2:24Speaker 1: are generally limited to glue fuming, power processing, and blood reagents.
- 2:30Speaker 1: Preservation methods include photography and lifting. Exemplars are intentional recordings
- 2:36Speaker 1: of the friction ridge skin of an individual. These may
- 2:39Speaker 1: be collected with pink ink powdered adhesive, electronic imaging, and
- 2:44Speaker 1: loor capture methods. These known exemplars can be used for
- 2:48Speaker 1: comparison against latent print evidence. Exemplars may include any in
- 2:52Speaker 1: all areas of friction ridge skin from the hands or
- 2:55Speaker 1: feet of an individual. Types of exemplars include fingerprints, palm prints,
- 3:00Speaker 1: major case prints, tips, joint sides of fingers, and footprints.
- 3:06Speaker 1: Martinez will explain what it means for comparison results to
- 3:09Speaker 1: return as inconclusive due to the quality or quantity, or
- 3:14Speaker 1: what it means for comparison results to be excluded. Latent
- 3:18Speaker 1: print comparison refers to the process of analyzing latent prints
- 3:21Speaker 1: and comparing them to known exemplars in an attempt to
- 3:24Speaker 1: determine their source. Examiners utilize the ace V methodology, which
- 3:31Speaker 1: is a specialized version of hypothesis testing. ACEV stands for analysis, comparison, evaluation,
- 3:39Speaker 1: and verification. Analysis is the assessment and documentation of friction
- 3:44Speaker 1: ridge impressions to determine suitability for comparison. This assessment includes
- 3:49Speaker 1: consideration of the quality and quantity of detail, orientation, anatomical source, finger, palm,
- 3:55Speaker 1: et cetera, type of matrix, deposition factors, complexity, substrate considerations,
- 4:02Speaker 1: environmental factors, development mediums, and preservation methods. Latent prints may
- 4:08Speaker 1: be of value for comparison, or it may be deemed
- 4:10Speaker 1: to contain insufficient detail for comparison purposes. Impressions deemed of
- 4:16Speaker 1: value are impressions that, in the opinion of the examiner,
- 4:20Speaker 1: contain sufficient quantity, quality, and specificity of ridge detail to
- 4:24Speaker 1: warrant a comparison. Examiners also take into consideration how discriminating
- 4:30Speaker 1: the location and arrangement of features within an impression are.
- 4:34Speaker 1: When quantity is low, quality must be relatively high, whereas
- 4:38Speaker 1: when quality is low, quantity must be relatively high. It's
- 4:43Speaker 1: not uncommon for latent print examiners to have conflicting opinions
- 4:46Speaker 1: with regard to sufficiency. Latent prints are also evaluated for
- 4:51Speaker 1: their suitability for database entry afis, ABIs, andbis, et cetera.
- 4:58Speaker 1: Comparison is a side by side, back and forth examination
- 5:01Speaker 1: of friction ridge detail between the latent print and known
- 5:05Speaker 1: print to determine whether the detail is in agreement or
- 5:08Speaker 1: disagreement based upon features, sequences, and spatial relationships within the
- 5:13Speaker 1: tolerance of clarity and distortion. Generally, latent prints are first
- 5:18Speaker 1: compared against various known prints belonging to subjects associated with
- 5:22Speaker 1: the evidence, victims, witnesses, and or suspects if known. In
- 5:27Speaker 1: the event that the latent prints are not identified or
- 5:30Speaker 1: there are no known prints available with which to compare,
- 5:33Speaker 1: the prints may be entered into a computer database n
- 5:36Speaker 1: BIS and compared to a large group of persons who
- 5:40Speaker 1: have prints on file. Evaluation is the formulation of a
- 5:44Speaker 1: conclusion based upon analysis and comparison of friction ridge impressions.
- 5:49Speaker 1: Conclusions that may be reached are source identification, source exclusion,
- 5:54Speaker 1: or inconclusive. Source identification is the examiner's opinion that two
- 5:59Speaker 1: impressions originated from the same source. The observed features are
- 6:04Speaker 1: sufficient correspondence such that the examiner would not expect to
- 6:08Speaker 1: see this level of agreement in impressions that came from
- 6:11Speaker 1: different sources, Nor did the examiner find features in disagreement
- 6:15Speaker 1: that would lead them to conclude that the impressions are
- 6:18Speaker 1: from different sources. There is no scientific basis for a
- 6:22Speaker 1: predetermined number of corresponding friction ridge details to be present
- 6:27Speaker 1: into impressions in order to affect a source identification. Source
- 6:32Speaker 1: exclusion is an examiner's conclusion that to impressions did not
- 6:36Speaker 1: originate from the same source. The observed features are in
- 6:39Speaker 1: disagreement such that the examiner would not expect them to
- 6:43Speaker 1: have originated from the same source. Inconclusive is an examiner's
- 6:47Speaker 1: inability to reach a conclusion of source identification or exclusion.
- 6:53Speaker 1: Inconclusive may be due to lack of quantity or quality
- 6:56Speaker 1: of detail in the latent or known Impressionation is the
- 7:01Speaker 1: independent examination by another qualified analyst using the ACE methodology
- 7:06Speaker 1: to either support or refute the conclusions of the original examiner.
- 7:10Speaker 1: ISPF requires verification of all conclusions rendered in a case
- 7:16Speaker 1: value determinations, identifications, exclusions, and inconclusives. Routine verification is considered open.
- 7:24Speaker 1: This means the verifier conducts independent analysis but has the
- 7:29Speaker 1: access to the original analyst notes and images. Blind verification
- 7:34Speaker 1: in which the verifier has no knowledge of or access
- 7:37Speaker 1: to the original analyst. Conclusion may be performed in cases
- 7:41Speaker 1: of single identifications generated from a database, as it means
- 7:46Speaker 1: a conflict resolution or as an additional quality measure for
- 7:50Speaker 1: complex impressions. Martinez may describe the Multi Modal Biometric Identification
- 7:56Speaker 1: System NBIS. NBIS is the general term referring to any
- 8:02Speaker 1: system that contains a database of ten print, latent prints,
- 8:06Speaker 1: and pom prints. MBIs also includes software that is utilized
- 8:10Speaker 1: to search available databases. IDAHO is a member of the
- 8:14Speaker 1: Western Identification Network and is able to search the databases
- 8:19Speaker 1: of WHEN Central Site members and the FBI. MBIs allows
- 8:24Speaker 1: for searching latent prints against known fingerprint and pomp print
- 8:27Speaker 1: database records. This system can be used to search latent
- 8:31Speaker 1: prints against other latent prints. Martinez made several fingerprint comparisons
- 8:37Speaker 1: in this case. The details of Martinez's involvement in the
- 8:40Speaker 1: case can be found in multiple reports, including Report five
- 8:44Speaker 1: Bates pages eight fifty one through eight eighty nine, Report
- 8:48Speaker 1: ten Bates pages eight ninety nine through nine thirty. Report
- 8:52Speaker 1: nineteen Bates pages nine ninety through nine ninety five. Report
- 8:57Speaker 1: twenty three Bates pages five, nine, nine six through five
- 9:01Speaker 1: nine one nine. Report twenty four Bates pages five nine
- 9:05Speaker 1: two oh through five nine two seven. Report twenty seven
- 9:09Speaker 1: Bates pages one three, five seven, eight through one three
- 9:12Speaker 1: six one four Report thirty AV zero zero zero three
- 9:16Speaker 1: zero eight and Report thirty two AV zero zero zero
- 9:21Speaker 1: three zero eight. In addition, Report thirty eight Bates pages
- 9:26Speaker 1: fifteen nine forty through fifteen nine forty seven, forty BAITS
- 9:30Speaker 1: pages fifteen nine fifty two through fifteen nine sixty one,
- 9:34Speaker 1: and forty one Bates pages fifteen nine twenty three through
- 9:39Speaker 1: fifteen nine thirty five have comparison results. Martinez was present
- 9:44Speaker 1: at eleven twenty two King Road in Moscow, Idaho, in
- 9:46Speaker 1: November twenty two for the purpose of photographing the crime scene,
- 9:51Speaker 1: the collection of evidence, and scene processing. This can be
- 9:55Speaker 1: found in Martinez Report eleven Bates, pages fourteen nine twenty
- 9:59Speaker 1: one one through fourteen nine fifty nine. Additionally, Martinez was
- 10:04Speaker 1: present at sixteen thirty Northeast Valley Road G two oh
- 10:08Speaker 1: one in Pullman in December twenty twenty two for the
- 10:11Speaker 1: purpose of photographing the apartment and collecting potential evidence. Following this,
- 10:17Speaker 1: Martinez accompanied other forensic scientists and investigators to fourteen seventy
- 10:22Speaker 1: five Northeast Glen Terrell Mole Wilson Short Hall, Room twelve
- 10:27Speaker 1: in Pullman, where Martinez took photographs the explanation of these
- 10:31Speaker 1: visits outlined in Martinez Report twenty five Bates, pages nine
- 10:35Speaker 1: three two three through nine three five four. All right, folks,
- 10:39Speaker 1: we're gonna wrap up right there, and in the next
- 10:41Speaker 1: episode we're gonna pick up with Jade Miller. All the
- 10:46Speaker 1: information that goes with this episode can be found in
