On January 26, 2011, 27-year-old Ellen Greenberg left work early when a snowstorm hit Philadelphia. She stopped for gas on her way home, then spent the afternoon grading papers in the apartment she shared with her fiancé, Sam.
That evening, Sam called 911 to report that he had found Ellen in the kitchen with a knife in her chest. She had been stabbed twenty times, including multiple wounds to the back of her head and neck.
At first, the Medical Examiner ruled her death a homicide. But weeks later, the ruling was changed to suicide, shocking many.
