CHESTER COUNTY, Pennsylvania (WPVI) — The Chester County District Attorney’s Office announced an update on the investigation into the death of Ellen Greenberg on Friday.

The prosecutor’s office said they cannot move forward with criminal charges and are placing the investigation on an “inactive status.”

Greenberg was 27 when she was found dead of more than 20 stab wounds in her locked Manayunk apartment in 2011.

She was discovered by her fiance on January 26, 2011, at the Venice Lofts in the 4600 block of Flat Rock Road. He was never named a person of interest in the case.

Greenberg’s family has long sought to change his suicide ruling to homicide or undetermined, filed two lawsuits against the city.

The Philadelphia Police Department as well as the Philadelphia District Attorney’s Office investigated the case, which was initially ruled a homicide after an autopsy. That initial determination was later changed to a suicide by the Philadelphia Medical Examiner’s Office.

Then, in 2019, the investigation was turned over to the Pennsylvania Attorney General’s Office for review, as Philadelphia District Attorney Larry Krasner had previously represented the Greenbergs.

The General Prosecutor’s Office agreed with the determination of suicide. But in July 2022, the AG’s Office handed the case back to Philadelphia

However, to avoid the appearance of a conflict of interest, the investigation was thenturned over to Chester County detectives in August 2022.

Since then, Chester County investigators say they have been working to determine if there is enough evidence to reopen the investigation.

On Friday, those investigators revealed that their team had determined they could not prove “beyond a reasonable doubt” that a crime had been committed, adding that without that standard of proof, it places the investigation in an “inactive status.”

Officials added that there is no statute of limitations for criminal homicide in Pennsylvania.

“As the investigation may take new directions, we are not closing the case,” the Chester County District Attorney’s office said in a news release.
