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.

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.
