PITTSBURGH (AP) - Two sisters of an Iowa state representative have been found dead of apparent gunshot wounds in their Pittsburgh home, and police say they are investigating the case as a double homicide.
Authorities say the bodies of 44-year-old Susan Wolfe and 38-year-old Sarah Wolfe were found Friday afternoon in their basement after they didn't show up for work. Police found Sarah Wolfe's car early Saturday parked nearly a mile away.
Sarah Wolfe was a psychiatrist for Western Psychiatric Institute and Clinic, and Susan Wolfe was a teacher's aide at Hillel Academy in the city.
Pittsburgh police Lt. Daniel Herrmann says they don't have a motive for the killings, and there were no signs of forced entry.
A sister, Mary Wolfe, is an Iowa Democratic state representative who lives in Clinton.
