Fiancé of teacher found with 20 stab wounds suggests what led to her 'suicide'

As the parents of 27-year-old Ellen Greenberg, a Philadelphia teacher whose 2011 death was ruled a suicide after she was found with 20 stab wounds and covered in bruises, advance from a significant legal battle this week, Greenberg's fiancé, Sam Goldberg, spoke publicly about her death for the first time.

Greenberg's parents, Dr. Josh and Sandee Greenberg, have been entangled in court fights with the government since their daughter's death, contesting the determination that it was a suicide.
