Her lifeWeekend and sceneInvestigationThe ContradictionRecords and memory

She grows up in Livermore, California, about an hour east of San Francisco, and plays piano from childhood. Friends and family called her Ziggy, according to TCNJ’s campus police chief. Her father had taught at Princeton University before the family moved west.

1976 to 1977Graduate study at Trenton State CollegeHer lifeDisputed

She enrolls at Trenton State College in Ewing Township, New Jersey, now The College of New Jersey, to study music and education with the goal of teaching. Accounts disagree on her program: most say music and education, a 2021 campus newspaper profile says music performance, and a Weird NJ account calls her a 21-year-old undergraduate. She was 25 and a graduate student.

September 2, 1977Back on campus, locked out of her lodgingWeekend and sceneDisputed

She returns six days before classes. The family she had arranged to live with is away, so she begins sleeping on a couch in the green room of Kendall Hall, the campus theater. Accounts disagree on whose home it was. A 1977 Signal article, as summarized in 2011, placed her at the house of music professor Stanley Austin. Netflix describes her hosts as a local fireman’s family. Solve the Case states she never rented from Austin.

September 3, 1977 · About 7:00 p.m.A cast member finds her asleep and offers her a beerWeekend and scene

A local theater group is staging J.B. in Kendall Hall’s black box theater that night. A cast member, identified by Netflix as Chuck, walks into the green room and wakes her. They talk, and he gives her a beer. Among her belongings police later find a playbill with his name circled and a note calling him a nice man who gave her a beer.

September 3, 1977 · EveningShe watches J.B. and tells the cast about an argument with a manWeekend and scene

She attends the performance and talks with actors at intermission. After the first act she seems friendly and upbeat. Later her mood drops, and she tells a cast member she had argued with a man and lost. His identity has never been established.

September 3 to 4, 1977 · Late nightLast sighting, last journal entry, the building emptiesWeekend and scene

A cast member recalls seeing her around 11:30 p.m. Solve the Case records her last journal entry at 11:43 p.m., noting the cast and crew were nearly done cleaning up. The 1977 Signal reported the cast and crew had left by 12:30 a.m. and all doors were locked.

Sources: Netflix Tudum; Solve the Case timeline; The Signal, Oct. 4, 2011 (summarizing Sept. 6, 1977 issue).

September 4, 1977 · DaytimeThe missing dayWeekend and sceneDisputed

Her whereabouts on Sunday are unknown. A report that she was seen at a local movie theater was never corroborated. Accounts also disagree on when she died: Princeton Info, summarizing the Netflix episode, wrote that she was likely killed after the play ended and lay undiscovered for a day, while Solve the Case’s summary of the medical examiner’s work puts the estimated time of death between 7 and 10:30 p.m. on September 4.

September 4, 1977 · 11:29 p.m.Patrolman Thomas Kokotajlo finds her on the main stageWeekend and scene

On routine patrol, Kokotajlo sees a girl’s bicycle locked with a cable to the railing at the foot of the steps to Kendall Hall’s side entrance, which faces Crowell Hall. He radios the campus desk, unlocks the side door, checks the small theater, and enters the main stage area, lit only by emergency lights. From 25 to 30 feet away he takes the figure on stage for a dummy. Up close it is a body under white material, the head badly lacerated. He finds no pulse; the wrist is cold and stiff.

He radios Ewing police and campus Sgt. Holmes, draws his weapon, and removes the padlock on the large loading door, which opens only about a foot and a half. He stays crouched 10 to 15 feet from her until Holmes and Ewing officers arrive. A search of the building finds no one.

September 4, 1977 · The sceneLocked doors, a loose lock, and no weaponWeekend and sceneDisputed

Kokotajlo had to unlock the side door to get in, and he wrote that he opened the stage’s loading door by removing its padlock, without saying whether it was locked or how he took it off. Solve the Case reports no sign of forced entry and a basement-level door with a loose lock that students knew how to jiggle open. The medical examiner’s scene description records blood beneath the piano, a small pool of blood holding her head scarf, one broken earring near her body, a pair of shoes and socks beside the piano, and a folded sleeping bag by the piano. The weapon is never found. The Unsolved Mysteries case page separately places her purse and diary in the green room.

September 5, 1977 · Overnight into morningDeputy Medical Examiner Dr. Raafat Ahmad performs the autopsyThe ContradictionDisputed

Report No. 77-199 lists nine anatomical findings: lacerations of the scalp and face; comminuted fractures of the right skull, both maxillary bones, and the left anterior cranial fossa; multiple contusions of the body; contusions of the frontal lobes; bilateral subconjunctival hemorrhages; fractures of the left seventh and eighth ribs; and contusions of the left lower lung lobe, the caecum area, and the fundus of the uterus. Cause of death: massive blood loss from the lacerations and fractures of the skull and face, contributed to by being struck and beaten with a blunt hard object. Copies went to the prosecutor and Ewing Township police.

The published report page lists no finding of sexual assault and no wrist marks. Netflix’s 2024 companion article states that a vaginal swab revealed sperm and that detectives believed she was sexually assaulted. Solve the Case places Ahmad’s arrival around 1 a.m. and the autopsy that morning.

September 8, 1977“Slain coed not raped”The Contradiction

Three days after the autopsy, the New York Daily News runs a story under this headline. It is the earliest published source Clutch Justice has traced for the claim that she was not sexually assaulted. The claim is wrong: Dr. Raafat Ahmad, who performed the autopsy, says on camera in the 2024 Unsolved Mysteries episode that Sigrid was raped. The one-page autopsy summary has no line for sexual assault, and the swab result Netflix later reported does not appear on it.

The New Jersey State Commission of Investigation reports that deficient sudden-death investigations can be identified in every county.

December 1981 to 2006Another Ahmad ruling, revisited two decades laterThe Contradiction

In the death of Norma Williams in Trenton, Dr. Ahmad, by then Mercer County Medical Examiner, lists the manner of death as undetermined, and police close the case without charges. Williams’s sons push to reopen it in 2001. Reviewing her own autopsy in May 2002, Dr. Ahmad concludes the injuries fit a beating, not a vehicle strike. Walter Townsend is convicted of murder; the New Jersey Supreme Court reinstates the conviction in 2006. This case is not connected to Sigrid’s.

Answering a Courier-Post piece that filed the case under Weird NJ, Denise Fanelli, a Trenton State freshman in September 1977, writes that the Trentonian headlined a campus of fear while there was no discussion on campus at all.
