In January 2011, 27-year-old teacher Ellen Greenberg was found dead in her Philadelphia apartment. She had been stabbed twenty times.

The door was locked from the inside.

Initially ruled a homicide, her manner of death was later changed to suicide a decision that continues to spark controversy, legal battles, and intense public debate.

In this episode, we examine the forensic findings, the conflicting conclusions, and the broader questions about locked-room cases and investigative standards.
