PITTSBURGH —

Target 11 investigator Rick Earle reported that new clues have been revealed in the mysterious  deaths of two East Liberty sisters.

Sources told Earle that police found a pair of gray sweatpants with a business card in the pocket next to the sisters’ stolen car.

The car was stolen from the sisters’ home on Chislett Street last week. Dr. Sarah Wolfe and her sister Susan were found shot to death in the basement of their home last Friday.

Police found their car the next day near the Carnegie Library. Police have also said they have video of a man who was with Susan Wolfe prior to her death. Investigators believe that man is the same person who took their car.

So far, that man has not been identified.

Sarah Wolfe, 38, a psychiatrist for Western Psychiatric Institute and Clinic, and Susan Wolfe, 44, a teacher's aide at Hillel Academy of Pittsburgh in Squirrel Hill died in a home the younger sibling bought in December on Chislett Street. Friends and police went to the home when the women did not show for work. They found the bodies in the home's basement.

Investigators said one of the sisters was found naked, and her body was doused in cleaning supplies, including bleach and laundry detergent.
