A new twist was uncovered in the death investigation that started 15 years ago and has received worldwide attention since. The investigation into the death of 27-year-old school teacher Ellen Greenberg has been a long road for her family and the city of Philadelphia. And now, the U.S. Attorn ey’s Office for the Eastern District of Pennsylvania is interested in the Ellen Greenberg case, according to several sources.

Greenberg was discovered by her fiancé in January of 2011 inside their 6th floor apartment in Philadelphia’s Manayunk neighborhood. The 27-year-old had 20 stab wounds.

The 32 page report cited several factors including Ellen’s struggle with anxiety, the number of hesitation wounds on her body and that there was no evidence that she was in an abusive relationship or that anyone else was inside the apartment the day she died.
