Investigators identified Gregory Rohn months after finding his remains, but forensic limits prevented the coroner from determining exactly how he died.
JOHNSTOWN, Pa. — Months of decomposition inside a concealed attic space left investigators unable to determine exactly how Gregory Rohn died, even as witness statements later helped police build a separate case against a woman accused of hiding his body.
The distinction between those two questions — how Rohn died and what happened to his body afterward — has shaped the investigation from the beginning. Angela Rice, 41, was arrested in Schenectady, New York, in August 2026 and returned to Pennsylvania to face a charge of abuse of a corpse. Police say evidence linked her to the concealment of Rohn’s remains inside an Adams Street residence in Johnstown. The verified public record does not show that Rice has been charged with causing his death, and the coroner has continued to classify the death itself as undetermined.
Rohn was 36 when he disappeared in December 2023. His mother reported him missing after picking him up from the Cambria County Jail and later dropping him off, according to court information cited in local reporting. Rohn told her he intended to visit a friend in the Old Conemaugh Borough area. Police subsequently learned that he had been at Rice’s Adams Street home. Rice told investigators that Rohn stayed there on Dec. 23 but was gone when she returned from a trip to Hornerstown the next day, according to accounts of the criminal complaint.
Police did not recover Rohn’s body at that time. He remained listed as missing even after officers received several reports in January 2024 that a dead person might be inside the attic of the same residence. Court records described in news reports said 911 calls came in between Jan. 15 and Jan. 17. Officers tried to contact people at the property on multiple occasions but were unsuccessful. The available accounts do not identify the callers or establish what evidence, if any, officers had at that point that would have allowed them to determine whether the report was accurate.
By June, conditions inside the home provided new evidence. Police returned to the Adams Street residence on June 29 for a welfare check. Officers reported seeing numerous flies inside a window and noticing a strong odor they associated with decomposition. Firefighters helped them enter. Investigators searched the house and eventually found human remains wrapped in a tarp and concealed in a confined attic or crawl-space area off a third-floor bedroom. The body had been hidden long enough that decomposition was advanced and much of the remains had become skeletal.
Cambria County Coroner Jeff Lees estimated that the person had been dead for approximately five or six months. The condition of the remains created immediate problems for forensic investigators. Basic questions that might be answered quickly after a recent death had become harder to resolve. The person could not be visually identified. Soft tissue had deteriorated. The passage of time complicated toxicology testing. Investigators also had to distinguish between damage connected to decomposition and any potential injury that might have occurred before death.
Dental records ultimately identified the remains as Rohn in August 2024. Once investigators knew whose body they had found, the forensic examination turned to the cause and manner of death. Local reporting said the autopsy did not reveal evidence of traumatic injury sufficient to explain what happened. Fentanyl was detected, but its presence alone could not establish a fatal overdose. Months of decomposition meant toxicologists could not calculate a reliable drug concentration that could be compared with levels associated with fatal intoxication.
That limitation prevented Lees from declaring an overdose as the official cause of death. Instead, Rohn’s death was classified as undetermined. The ruling means the available medical evidence did not allow the coroner to identify a sufficiently supported cause. It does not establish that an overdose did not occur, but neither does it establish that one did. That nuance became particularly important later, after police received statements from people who said Rice had described Rohn as dying from an apparent overdose.
According to reporting based on the criminal complaint, one acquaintance told investigators that Rice said Rohn had overdosed and that she concealed his body. Other people interviewed by police reportedly described similar statements attributed to Rice. One account said Rice referred to the body as being “in the walls in the attic.” Those claims gave investigators information about what Rice allegedly knew and did, but they did not substitute for the forensic evidence needed to make an official medical determination about the cause of death.
Police therefore pursued the part of the case they said the available evidence supported: the alleged concealment of the remains. Pennsylvania law prohibits abuse of a corpse, including treatment of a dead body that a person knows would outrage ordinary family sensibilities. The charge filed against Rice is a second-degree misdemeanor. It does not require prosecutors to prove that she caused Rohn’s death. Instead, prosecutors would have to establish the elements of the alleged mistreatment or concealment of his body.
The physical condition in which investigators found Rohn became significant to that allegation. The remains had been wrapped in a tarp and placed in a hidden upper section of the house rather than left in an open living area. Detective Sgt. Cory Adams of the Johnstown Police Department described the concealment as unusual compared with the many death investigations he had handled. Lees also emphasized after the discovery that the placement of the body was not consistent with a person simply dying in that location without later intervention.
Investigators still faced the problem of locating Rice after the charge was filed. Authorities eventually found her in Schenectady and returned her to Cambria County in August 2026. She was arraigned and jailed. Local reporting listed bail at $200,000 and said a preliminary hearing was scheduled for Sept. 10 before Magisterial District Judge Brian Subich. The reliable public material reviewed for this article does not establish the result of the scheduled hearing or document a later change to the charge.
The unresolved medical question prevents the case from being described accurately as a confirmed overdose death. Fentanyl was present, but investigators could not determine a reliable level. Witnesses described an alleged overdose, but those statements are not the same as a toxicology conclusion. No reported traumatic injury established another cause. As a result, the official finding remains undetermined even though investigators developed a theory about what may have happened before Rohn’s body was concealed.
The case also illustrates how time can narrow the range of conclusions available to forensic investigators. By the time police recovered Rohn, several months had passed since his disappearance. That delay affected identification, examination of the remains and the ability to measure substances in his system. Investigators could still document where the body was located, how it had been concealed and what witnesses later told them, but some information about Rohn’s final moments may have been lost permanently.
For prosecutors, that means the abuse-of-corpse allegation stands on a different evidentiary foundation from the unanswered death investigation. The concealment charge is based on the location and condition of the remains and on statements police say were made by Rice and others. The cause-of-death question remains limited by the forensic record. Authorities have not publicly established that Rice killed Rohn, and no verified source reviewed for this article documents a homicide charge against her.
Rice is presumed innocent unless proven guilty. Rohn’s cause of death remains undetermined, while the criminal case concerns the allegation that his body was deliberately hidden after he died. The later procedural outcome following Rice’s August 2026 arraignment has not been reliably established in the public material reviewed.
