When 27-year-old teacher Ellen Greenberg was found dead in her Philadelphia apartment during a snowstorm in 2011, the discovery shocked the community. She had been stabbed 20 times — in the neck, head, and chest — with a knife still lodged in her body. At first, investigators ruled her death a homicide, but within weeks, that ruling was mysteriously changed to suicide. Now, over a decade later, officials have reaffirmed that same conclusion — a decision that has reignited anger and heartbreak for Ellen’s family, who remain convinced she was murdered.
