The Evidence Left on the Stage: New Questions in the Murder of Sigrid Stevenson

Nearly fifty years after Sigrid Stevenson was found on the main stage of Kendall Hall, the original police report, the medical examiner’s summary, a 1977 floor plan, and the crime scene photographs are public. Read together, they ask sharper questions than the story everyone repeats.

I was a theatre kid. So when I first read about Sigrid Stevenson, the part that stayed with me was not the ghost story. It was that she spent her last weekend in a theater, sleeping on the green room couch, watching a local cast put up J.B., chatting with actors at intermission, and playing a piano on an empty stage after everyone went home. Anyone who has ever stayed late after strike knows that feeling. Her death is one of the saddest stories I know, because she died somewhere she clearly felt at home and should have been safe.

In April, I wrote that her case was inadequately investigated when the investigation had its best chance. That piece leaned on press accounts and secondhand reconstructions. Since then I have gone back to the documents themselves. They complicate the story in specific, testable ways, and that is what this piece is about.

I will be honest about where I am with this one. This case really bothers me. I cannot get it out of my craw that the version everyone accepts, a young woman struck down at a piano while she played, does not make sense at all once you put it next to the photographs and the paperwork. Every time I go back to the records, the story people tell gets thinner.

The Three Documents

The first is a Trenton State College Investigation Report, station case 77-476, filed by Patrolman Thomas M. Kokotajlo and dated September 5, 1977. The second is a single typed page headed with Sigrid’s name and the number 77-199: the medical examiner’s anatomical findings, cause of death, and crime scene description, copied to the prosecutor and Ewing Township police. The third is a photocopied first-floor plan of Kendall Hall, hand-annotated to show the main stage, the small stage where J.B. played, her belongings, the piano and chair, her body, her scarf, and an overhead door.

Solve the Case, a nonprofit cold case platform, hosts all three alongside roughly a dozen scene photographs, and Netflix published some of the same material with its 2024 Unsolved Mysteries episode. None of it is the full case file. The medical page is a summary, not the signed autopsy. That limit matters for everything below.

What Kokotajlo Actually Wrote

Kokotajlo’s report is one page. On routine patrol at 11:29 p.m. on Sunday, September 4, he saw 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 radioed the campus desk, unlocked the side door, checked the small theater as he passed, and walked toward the main stage, where the only light came from emergency fixtures.

From about 25 to 30 feet away he saw what first appeared to be a dummy lying on the stage. Closer, it was a body under white material, the head badly lacerated, blood on her and on the floor. He felt her wrist for a pulse and found none. The wrist, he wrote, was cold and stiff.

He radioed Ewing police and campus Sgt. Holmes, drew his weapon, and stepped back to the large loading door. He removed its padlock, but the door would only open about a foot and a half from the floor. He stayed crouched, facing the auditorium and Sigrid, 10 to 15 feet from her, until Holmes and then Ewing officers arrived. A search of the building found no one.

Laid over the 1977 floor plan, his route is plausible: in through a side entrance on the east end of the building, past the small auditorium where J.B. had played, and into the main stage wing near room 117. His report describes two separate thresholds, though. First he looked through swinging doors facing the auditorium. Then he walked through a doorway onto the stage. The plan has to fit both, and the exact path he took is not marked on any published record.

Three details in that page matter later. He had to unlock a door to get in. The stage was lit only by emergency lights. And he opened the loading door himself.

The Door at the Back of the Stage

The wide scene photographs show a large metal roll-up shutter at the back of the main stage, its bottom edge sitting above the floor with a dark gap beneath it. Stacked lumber and platforms sit to its right. The 1977 floor plan marks an overhead door in that same rear wall.

It is tempting to read that gap as a way in or out. Kokotajlo’s report points somewhere more ordinary. He describes stepping back from Sigrid to the large loading door, removing a padlock, and raising it about a foot and a half while keeping her in view 10 to 15 feet away. The 2024 Unsolved Mysteries episode confirms it: the shutter in the photographs is the loading door he opened. The gap is his, made after he found her.

That settles what the gap is. It does not settle what the door was before he touched it. It had a padlock on it when he arrived, and whether that lock was closed decides whether the rear of the stage was a way out that night.

The padlock raises its own question, and his wording is exact. He wrote that he opened the door by removing pad lock and that it would only rise about a foot and a half. He does not say he unlocked it, used a key, cut it, or found it hanging open. That silence stands out because of how precise he is a few lines earlier. At the side door, he wrote that he unlocked it. At the loading door, minutes later and under far more pressure, he wrote only that he removed the lock. An officer who has just told us he used a key on one door would be expected to say so about the second. The plainest reading of his own words is that the padlock came off without one, which would mean it was sitting there unlocked. The report does not say that outright, and it is the question he could still answer. The difference matters. A locked padlock that an officer opened with an authorized key describes a secured door. A padlock lifted out of its hasp without a key describes a door anyone on that side could have opened.

His report shows he carried at least one key, because he unlocked the side door to get in. It does not identify that key, and it does not establish that the same key fit the loading door. Sources familiar with the theater program at the time told Clutch Justice that the padlock secured a garage-style door at the rear of the stage used to bring in construction materials for the main stage. According to those sources, theater faculty described the door as kept locked by that padlock, with only a limited number of people holding keys, and campus police may not have been among them.

If that is right, his wording carries more weight. A campus officer without a key could only have removed that padlock if it was already open. That would mean someone in a small circle of keyholders left the rear of the stage unsecured that weekend, or someone opened it. If he did have a key, his report does not say where it came from. Either way, the list of people who held keys to that lock in September 1977 is one of the most important records in this case, and it has never been published.

Which side the hasp was on matters just as much. A padlock fastened on the stage side can only be closed from inside the building. If it was locked when he reached it, no one left through that door unless someone with a key closed it behind them. If it was open, the door was an exit no one had secured. The other question is whether anyone documented the padlock’s condition before he removed it, and whether the lock itself was collected, photographed, or examined for fingerprints.

Keys and campus officers come together in one more place. Netflix reports that months after the murder, an unnamed campus security officer told a colleague he had killed Sigrid, and that further investigation found no conclusive evidence. He was never charged and is presumed innocent, and no published record says whether the remark was a confession, a boast, or something else. Campus officers carried building keys. Their handcuffs were tested because of the marks on her wrists. And the records of how that statement was investigated, by whom, and how it was closed have never been released.

Three Places She Bled

The medical examiner’s crime scene description lists blood beneath the piano, a small pool of blood with her head scarf in it, and a lot of clotted blood around her body on the stage, plus blood splattered down from the stage edge. The annotated floor plan places those in different spots: the piano and chair toward center, her body to one side, and the scarf with blood near the lip of the stage by the orchestra pit.

The photographs show the same three locations. Beneath the piano, the stain is concentrated on the floor: an area of accumulated blood with irregular extensions, not an obvious field of fine droplets. That is a description of what the images show, not a bloodstain-pattern classification. In the wide shots, the piano’s upper panels look comparatively clean, though the keys, the top, and the seat area are not shown well enough to judge. The close-ups tell a lower story: smears and drops on the bottom rail of the piano at floor level, right where the floor stain spreads out from under it. There is a large pool around the scarf with a line of drops along a floorboard seam. And the heaviest pooling surrounds her body, some distance from the piano.

There is a fourth surface to account for. Kokotajlo found her under white material, and Netflix describes her as wrapped in a piano blanket. A frame in the 2024 episode shows that blanket laid on the stage floor with dark drops scattered across its top surface, separate from any stain soaking through from beneath. If those drops are blood, something bloody was above the blanket after it was spread out: hands, a weapon, or her own movement. A piano blanket is also what covers a piano that is not being played, which matters for the keyboard question below. If it was pulled off the piano to cover her, the piano was covered before it was a crime scene.

The version of this case that has circulated for decades has Sigrid struck from behind while playing and killed at the keyboard. Blood collecting beneath a piano does not mean the fatal blows landed there. She could have been hurt nearby and bled at that spot, been moved, or been injured again somewhere else. The medical findings also go well past a head wound: severe injuries to the face and skull, broken ribs, and damage to internal organs. That is not the profile of a single strike at the keyboard. It describes a sustained assault, and its sequence has to be rebuilt from the whole body and the whole stage, not from one pool. Scanned photographs cannot do that alone. Bloodstain analysis of the original scene photographs and diagrams, if the file contains them, could.

Two more details keep the question open. A close-up of her sheet music shows a single elongated drop with a tail running down the page and a smaller mark below it. That shape suggests the page was upright when the blood landed. It is also the only blood visible on the music, which is hard to square with a beating delivered at the keys, where a page that close would be expected to catch far more. And the white folding chair sits angled off the bass end of the keyboard, at the left of the wide photographs, close to the floor deposit, with no obvious staining on its visible surfaces. Whether it stood there during the attack or was moved afterward, the photographs cannot establish. She may have been standing. The chair may not have been where she sat.

The keyboard itself raises the same question. In the wide shots, no black keys are distinguishable where the keyboard should be, only a pale, even band below the music. That is what a closed fallboard would look like, but at this resolution it is also what open keys under emergency lighting could look like. If the cover was down, she was not playing when the attack began, and the most repeated image in this case, Sigrid struck at the keys, loses its anchor. Sheet music on the stand does not settle it either way, since music can sit on a closed piano. The original prints, or the photographer’s notes, would show whether the keys were covered.

What She Left by the Piano

The belongings photograph is the one I keep going back to. Beside the piano, her brown boots sit side by side. A burgundy sock is tucked into one of them. Her canvas bag is set down next to them, and her tan sleeping bag is rolled, a white cord trailing from it. The medical summary describes the same group: a pair of shoes and socks beside the piano and a folded sleeping bag.

Blood sits on the floor under the piano and on its bottom rail, inches away. In the photographs reviewed, the boots and the sleeping bag show none, and the canvas bag shows at most a few small dark marks near its strap that the scan is too soft to identify. Nothing in that pile looks thrown, kicked, or scattered. It looks neatly arranged, and whatever bled beneath the piano did not reach the things sitting beside it.

Now look at where that pile is. Sigrid had been sleeping on the couch in the green room all weekend, and her purse and diary were found there. That is documented, and it makes sense. The green room was where she slept. So why was her bed on the main stage? Her sleeping bag, her canvas bag, and her boots were not in the room she was living in. They were rolled, set down, and lined up beside the piano on the main stage, inches from the blood beneath it. A woman who planned to play for a while might carry her music to the piano. She would not usually bring her bedding with her. Either she packed up her whole camp and carried it onstage for a reason no record explains, or someone else moved her things there. If someone else did, the neatest pile on that stage may be the clearest sign that the scene was arranged after the fact.

That makes the pile evidence in a way it has never been treated. Netflix reports that her blouse was tied around her mouth, and investigators have since developed DNA from the knots in that bloodied shirt. Knots are where hands work hardest, and that is exactly the right place to look. But anyone who carried her bedding onto the stage, rolled it, and set her bag down beside it handled those things too. The sleeping bag, its ties, the canvas bag and its straps, and the boots belong in the same lab as the blouse. Touch DNA testing did not exist in 1977. It does now, and the items that may show someone else’s hands are sitting in an evidence room in Mercer County, if they were kept.

Then there is the sock, and no one talks about the sock. Her boots sit side by side with one burgundy sock tucked into one of them. The other sock is not in the photograph. The medical summary separately mentions a bloodstained sock, but no published record says where it was found, whether it is the mate to the one in her boot, or how it came to be bloody when the boots, the bag, and the sleeping bag beside the piano were not. She took off her boots and put one sock away like someone settling in for the night. The second sock ended up somewhere else, and it picked up blood that nothing else in that pile did. In nearly fifty years of retellings, I have not found one that mentions it.

Put it next to the sleeping bag and there are two soft things missing from a neatly packed pile: a sock and possibly a tie. Both could tell us something about how she was restrained or moved. That is a question, not a finding, until the evidence inventory shows where each item was recovered.

And her feet were dirty. The soles of her feet are dark with grime from the stage floor, the kind you only pick up walking around a theater barefoot. That fits the boots and the tucked sock: she took them off and kept moving, across the stage, into the wings, maybe back to the green room where her purse and diary were. She was comfortable there, and she was up and about without shoes for some time before she died. What her soles do not show is much blood, despite the heavy pooling around her. Soles that are dirty but nearly free of blood suggest she was on her feet before the bleeding began, and not much after. Bloodstain analysis of the original photographs would be needed to say that with confidence. If she was not walking once she was hurt, then the three places she bled raise a harder question about how she got from one to the next.

“Slain Coed Not Raped”

Three days after the autopsy, on September 8, 1977, the New York Daily News ran a story under the headline Slain coed not raped. That claim has traveled ever since. In 2011, a writer for TCNJ’s student paper, trying to replace the ghost stories with facts, wrote that the Mercer County medical examiner had determined Sigrid was not sexually assaulted. Weird NJ, the Odyssey, and several podcasts repeated it.

The medical summary page lists nine 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. It gives the cause of death as massive blood loss from the lacerations and fractures, with being struck and beaten by a blunt hard object as the contributing cause.

There is no line on that page for sexual assault, and no line for a swab. But the woman who performed the autopsy has answered the question herself. In the 2024 Unsolved Mysteries episode, Dr. Raafat Ahmad says on camera that Sigrid was raped. Netflix’s companion article states that a vaginal swab revealed sperm and that detectives believed she had been sexually assaulted, and Solve the Case’s summary of the medical findings adds pelvic contusions and sperm heads on the swabs.

So the 1977 headline was wrong, and it was wrong in a way that shaped every retelling after it. A three-day-old murder of a young woman on a college stage was reported to the public as not a rape, while the pathologist who examined her knew otherwise. Whether that came from police, the prosecutor’s office, or the college, and whether it was a mistake or a decision, is the question this case has never been made to answer. The swab is not a footnote. Netflix also reports that DNA testing excluded a J.B. cast member after his death in 2016, which means biological evidence from this scene survived long enough to be tested. The finding a 1977 headline erased may be the evidence keeping this case alive.

The campus, meanwhile, went quiet. Denise Fanelli was a freshman at Trenton State that September, and in a 2016 letter to the Courier-Post she remembered the Trentonian headlining a campus of fear while, on campus itself, there was no discussion at all. She described the subject as almost verboten by administration. No counselors, no vigils, nobody visibly afraid. Her letter was answering a Courier-Post piece that had filed Sigrid’s death under Weird NJ, and she called the ghost story a further insult to Sigrid’s dignity.

I read that letter and I think the administration was worried about its reputation more than it was worried about what happened on its stage. A college that does not want a rape on its campus has every reason to prefer a headline that says there was none. I cannot prove that is where “not raped” came from. I can say that the silence Fanelli describes and the error in that headline point the same direction, and that the college’s own records from that fall would show whether anyone was managing the story.

The Polygraphs, and a 1977 Pattern Michigan Knows

Investigators gave several dozen polygraph tests in this case, to students, staff, and campus officers. No published record names who administered them, what was asked, or whether a second examiner ever checked the charts. The only individual result anyone has reported is a pass. And the one person of interest the 2024 episode says was never tested is the maintenance worker the college fired soon after the murder.

I have seen this shape before. The same year Sigrid was killed, Michigan investigators polygraphed Christopher Busch in the Oakland County Child Killer case, and his test was publicly described as passed. Later documentation showed that three experienced examiners concluded he either failed or did not pass. Busch was the son of a General Motors executive whose family, according to a detective who worked the task force, paid victims’ families to stay away from police. He was never charged, and DNA testing has not matched him to the scenes. When Timothy King’s family sued for his file, the polygraph reports were withheld by statute, and the Michigan Court of Appeals agreed in 2013. I wrote about how that clearance shaped everything after it in Who Controlled the Information?

No published record connects these two cases, and I am not suggesting one. What I am suggesting is that we could be dealing with the same kind of failure here: polygraphs treated as answers instead of tools, never properly read, and people with connections to the institution quietly left out of the circle. In Sigrid’s case, the people closest to the college are exactly the ones whose clearances the public cannot see. A campus officer reportedly said he killed her, and how that was closed has never been released. A college employee with a building key was fired, not tested. Campus officers’ handcuffs were checked on the theory that cuffs made the marks on her wrists, a theory no published finding confirms, and the officers were then tested by examiners no one has named.

The Time of Death Problem

Rigor mortis alone cannot tell us whether Sigrid died a few hours before she was found or the night before. What it can do is test the reported death window against what the first officer described.

At 11:29 p.m. on September 4, Kokotajlo wrote that her wrist felt cold and stiff. Solve the Case attributes a death window of 7 to 10:30 p.m. that evening to Dr. Ahmad. Sigrid was last seen by a cast member around 11:30 p.m. on September 3, and Solve the Case dates her last journal entry to 11:43 p.m. that night. That gives these possibilities:

The National Library of Medicine’s StatPearls chapter on estimating time since death describes rigor appearing first in the small muscles of the face about two hours after death, spreading to the limbs over the next few hours, and completing six to eight hours after death. It typically persists to about 24 hours and is generally gone by 36. The same chapter cautions that real-world conditions vary widely and that estimates need more than one method.

Against that baseline, a stiff wrist 59 minutes after death would be unusual. At about four and a half hours, stiffening in the arms fits. At nearly 24 hours, persistent rigor is still possible. Solve the Case’s summary also reports that rigor was complete. When the medical examiner recorded that complete rigor matters a great deal: complete rigor at the scene around 1 a.m. would be very early for a death at 10:30 p.m.

Kokotajlo felt one wrist. He did not test her joints, take a temperature, or assess rigor across her body, and a body that feels cold is not the same as a measured temperature. His note is a field observation, not an examination. But it is the earliest physical observation in the record, and the late end of the reported window does not sit comfortably beside it.

Rigor is only one clock. The record holds two more, and they have never been read together.

The first is lividity. Solve the Case’s summary reports it was mostly on the front of her body, matching the face-down position she was found in. Blood settles where gravity pulls it, starting within half an hour to two hours after death and spreading into larger patches over six to twelve hours, according to StatPearls. Once it becomes fixed, it no longer shifts, which traditionally signals that more than twelve hours have passed. Lividity on her front tells us she lay face down from soon after death and was not turned over hours later. Whether it was fixed when Dr. Ahmad examined her is not in any published record, and that one word would narrow the window more than anything else in the file.

The second clock is the swab. Solve the Case’s summary of the medical findings reports sperm heads on the swabs. Not whole sperm. Heads. Tails are the first part to break down. In a living woman, the National Institute of Justice’s forensic training material says about a quarter of sperm have lost their tails by six hours, few still have tails by twelve, and by twenty-four hours mostly heads are left. Those times vary widely, the process after death is less studied, and slide preparation in a 1977 lab could knock tails loose on its own. But taken at face value, heads only does not look like an assault an hour or two before death on Sunday night. It looks like something that happened many hours earlier.

No single clock settles it. Each has caveats, and every one of these readings comes from a summary rather than the autopsy itself. But they do not disagree with each other. All four point earlier than 10:30 p.m. on Sunday, and two of them lean toward the night before, around the time her journal goes silent. The one thing in this case that points to Sunday evening is the window attributed to Dr. Ahmad, and no published record shows what it was based on.

The Medical Examiner Has Been Wrong Before

Dr. Ahmad has been wrong before, and she is the one who said so. Norma Williams died in Trenton in December 1981. Ahmad performed the autopsy and listed the manner of death as undetermined, and police closed the case without charges. Twenty years later, after Williams’s sons pushed for it to be reopened, Ahmad reviewed her own autopsy in May 2002 and concluded the injuries fit a beating, not a vehicle strike. Walter Townsend was convicted of the murder, and the New Jersey Supreme Court reinstated that conviction in 2006. For two decades, a homicide sat closed because of a ruling its own author later reversed.

That case has no connection to Sigrid’s, and one reversal does not make every ruling wrong. Ahmad served for decades as Mercer County’s medical examiner, and her willingness to go back to her own work is the reason Norma Williams’s family got an answer. But it matters here for a specific reason. In Sigrid’s case, the death window attributed to Ahmad is the one reading that does not line up with the rigor, the lividity, the swab, or the officer’s hand on a cold wrist. Her own record shows that a second look at her findings can change everything. Sigrid’s file has never had one in public.

The Medical Examiner’s System in 1977

In November 1979, two years after Sigrid’s death, the New Jersey State Commission of Investigation reported that deficient sudden-death investigations could be identified in every county in the state. It recommended replacing county medical examiners with regional offices run by certified forensic pathologists, and prosecutor units trained to secure scenes and preserve evidence. Its case studies came from Camden County, not Mercer, and it did not examine Sigrid’s case. It describes the system her case moved through.

Today, Mercer County contracts with Middlesex County for medical examiner services, and the county’s website directs autopsy report requests to the Middlesex County Medical Examiner.

A Thank-You to Scott

I want to thank Scott Napolitano. He first heard Sigrid’s name on a campus ghost tour as a TCNJ student and spent the years since trying, in his words to TCNJ, to make her a person and not just a ghost. He had no personal connection to her. He did it anyway, mostly alone, for a long time, and he was generous with me when I reached out. Independent work on a case like this can be isolating, especially when the questions push against the comfortable version of the story. His persistence is a large part of why there is a record to read at all, and why the practice room in TCNJ’s Music Building now carries her name.

The Records That Would Settle It

None of the questions above needs speculation to resolve. Each one points to a specific record.

If you hold any of these records, or know where they are, send them through Clutch Intel.

The note left with flowers on the steps of Kendall Hall in 2024 said The stage is forever your world. She deserves a reconstruction of what happened on that stage that comes from the records, not from the version that has been repeated the longest.

The evidence never left the stage. The story did.
