In the 11 days since two East Liberty sisters were found dead inside their home, Pittsburgh police have reviewed surveillance video from multiple locations as they search for evidence pointing to a suspect.
Monday evening, police released video of a man who rode a Port Authority bus with Susan Wolfe the night before she and her sister, Sarah Wolfe, were found shot to death inside their Chislett Street home Feb. 7 in a double slaying that has unnerved some area residents.
The release -- at least a week after police obtained the video -- provided the first glimpses the bureau has offered into detectives' attempts to find the killer. Police have released little information about the investigation and are treating it with high sensitivity.
Police do not consider the man in the video a suspect, "but merely a witness that could provide homicide detectives with essential information relevant to this investigation," according to a news release from major crimes Lt. Daniel Herrmann.
A source familiar with the investigation said police used a Port Authority ConnectCard belonging to one of the sisters to focus on video from a particular bus at a specific time and that the video contains images of the man and woman, presumably Susan, together both on and off the bus.
Detectives continued to visit at least a half dozen locations throughout East Liberty last week while searching for leads in the deaths of the sisters, whose bodies were found at the foot of their basement steps.
They reviewed footage kept by the Villa shoe and clothing store near Highland and Penn avenues, not far from where the lime green Ford Fiesta belonging to Sarah Wolfe, a 38-year-old psychiatrist, was found early Feb. 8 on Whitfield Street. Police also reviewed footage from the nearby Carnegie Library branch.
Susan's co-workers at the Hillel Academy in Squirrel Hill called police Feb. 7 and asked them to check on her well-being after the 44-year-old teacher's aide did not come to work. Susan went to work the day before and left about 5 p.m., saying she had an appointment, a co-worker told the Pittsburgh Post-Gazette shortly after her death.
Susan Wolfe was found naked. Sarah Wolfe was found clothed. Each died of a single gunshot wound to the head and sustained other unspecified injuries, according to Allegheny County medical examiner Karl Williams.
Sources say a liquid was poured over at least one of the women's bodies, possibly in an effort to conceal evidence.
