Ellen Greenberg was found dead in 2011 in her Philadelphia apartment with 20 knife wounds and numerous bruises. Authorities ruled her death a suicide. Fourteen years later, the pathologist who performed her autopsy says he’s changed his mind.

The cause of death of Philadelphia school teacher Ellen Greenberg, who was found brutally stabbed in 2011, will be reinvestigated after a pathologist who previously ruled her death a suicide reversed course last week.

Greenberg, 27, was found dead by her fiancé, who returned to their home in Philadelphia to find the door’s swing bar lock in use. After forcing his way in, her fiancé, Sam Goldberg, discovered Greenberg dead with a 10-inch knife in her chest.

The Greenbergs are also asking the Pennsylvania State Supreme Court to allow them standing to have their daughter’s death certificate amended from suicide to undetermined. That case is yet to be heard.

Finally, the issuing pathologist has changed his position 180 degrees. It’s consistent with what the Greenbergs have been contending all along,” said attorney Joseph Podraza Jr.

Ellen Greenberg's death was determined to be a suicide over a decade ago. But the former medical examiner said he no longer believes she killed herself.

The mother of Ellen Greenberg whose death was labeled a suicide 14 years ago, is speaking up about the police's decision to revisit the ruling.

The family’s attorney said the focus now shifts to who killed Ellen. “We'd like to find out who the murderer or murderers are.”
