A Philadelphia judge has ruled that the family of Ellen Greenberg, a teacher who was found dead with 20 stab wounds, can move forward with a lawsuit against the city Medical Examiner’s Office to remove from the record suicide as her official cause of death.

Greenberg’s body was discovered by her fiance in their Manayunk apartment in 2011. She was 27 years old. The coroner originally listed her cause of death as a homicide, but subsequently switched it to suicide without explanation.
