  Speaker 1: At eleven p m. On September twenty four, nineteen seventy seven,
• 0:05
  Thomas Cockotylow commenced his duties as a campus police officer
• 0:09
  at Trenton State College now known as the College of
• 0:13
  New Jersey, located in Ewing. While conducting his patrol around
• 0:18
  the campus, Cockotilo observed a bicycle secured to the railing
• 0:22
  outside Kendall Hall, which accommodates the main stage theatre. Given
• 0:27
  that the semester was still a few days away from commencing,
• 0:30
  Cockotilo contacted the dispatcher to inquire if anyone was expected
• 0:35
  to be present in the building that evening. Upon receiving
• 0:39
  confirmation that no one was scheduled to be there, he
• 0:42
  proceeded inside to conduct an investigation, noting that the theatre was
• 0:47
  locked and that he had to unlock it to gain entry.
• 0:52
  Upon entering the main stage, Cocotilo initially perceived what appeared
• 0:57
  to be an individual resting on the stage, leading him
• 1:01
  to question whether it was a person or merely a prop.
• 1:05
  As he approached the figure, he noticed a significant amount
• 1:09
  of blood and quickly discerned that it was indeed a person.
• 1:14
  The only clue indicating the individual was female, was an
• 1:17
  earring lying on the floor surrounded by a pool of blood.
• 1:22
  At that moment, every ewing police officer on duty that
• 1:26
  night arrived on the stage. Cocatajelo recounted in the Netflix documentary,
• 1:32
  The individual, identified as Sigrid Stephenson, a twenty five year
• 1:37
  old student at Trenton State College pursuing a master's degree
• 1:41
  in music and education, was recognized through her driver's license.
• 1:46
  A family friend featured in the docuseries described Stevenson as
• 1:51
  a piano prodigy. At approximately one a m. That night,
• 1:56
  doctor Rafat Ahmad, who served as the deputy medical exams,
• 2:00
  arrived at the scene. She informed Netflix's producers that the
• 2:05
  incident was one of the most gruesome murders she had encountered.
• 2:10
  During the autopsy conducted the following morning, investigators discovered lacerations
• 2:16
  on the back of Stevenson's head and the front of
• 2:18
  her face, extensive bruising across her body, and signs of
• 2:23
  sexual assault. Additionally, there were markings on her wrists suggesting
• 2:28
  she had been restrained. Doctor Ahmad concluded that the cause
• 2:32
  of death was massive cranial cerebral trauma to the head,
• 2:36
  indicating that Stevenson had likely been struck with a blunt object.
• 2:41
  Although her body was discovered at eleven thirty pm that night,
• 2:46
  doctor Ahmad estimated the time of death to be between
• 2:49
  seven point thirty and ten pm that evening. Stevenson had
• 2:53
  returned to campus on September second after a trip. Upon
• 2:57
  her arrival, she found herself without a commodation as her
• 3:01
  intended hosts were on vacation. Consequently, she opted to stay
• 3:06
  in Kendall Hall for a few days. The last confirmed
• 3:10
  sighting of Stevenson occurred around eleven thirty p m. On
• 3:14
  September third, after she attended a play in the black
• 3:18
  Box Theater, also located in Kendall Hall. Witnesses noted that
• 3:24
  she appeared to be in good spirits after the first act,
• 3:27
  but one cast member observed that she seemed upset after
• 3:31
  the second act, mentioning a disagreement with a man. Less
• 3:36
  than twenty four hours after the play, Stephenson was murdered.
• 3:41
  The Netflix docuseriies revealed that the crime scene yielded no
• 3:44
  finger prints or footprints, and there were no blood smears.
• 3:48
  The murder weapon was never recovered. Mystery at milemarker forty

• 4:04
  cousin's graduation party with her parents, located directly across the
• 4:08
  street from their home. At approximately nine to fifteen pm,
• 4:12
  Valiante departed from the gathering, prompting her mother, Diane Valiante,
• 4:17
  to receive a phone call from one of Tiffany's friends,
• 4:20
  who requested that she come over to their house. Diane,
• 4:23
  accompanied by Tiffany's father, Stephen, proceeded to the residence, where
• 4:28
  they encountered Tiffany's friend, alleging that she had misused her
• 4:31
  credit card. Initially, Valianti denied the accusation, However, she later
• 4:38
  confessed to the act after her friend had departed. Diane
• 4:42
  then entered the house to retrieve Stephen, and upon their
• 4:46
  return outside, they discovered that Valiante was missing. They promptly
