Zone 5 Cmdr. Tim O’Connor speaks at a public safety meeting Tuesday at the Union Project in Highland Park, urging residents to be vigilant and report any unusual activity in the wake of the killing of the Wolfe sisters.
One of two sisters found dead inside her East Liberty home last week was spotted on a Port Authority bus with a man the night before her body was found.
Investigators have obtained video of one of the sisters together with a man on a Port Authority bus, according to a source familiar with that portion of the investigation. Susan Wolfe, 44, typically took a bus from her job in Squirrel Hill to her home, while her younger sister, Sarah Wolfe, 38, drove.
Investigators were able to track the use of a ConnectCard belonging to one of the victims, which allowed them to focus on video from a particular bus at a specific time. Police have images of the two on the bus as well as outside the bus.
Among the theories being pursued by investigators is one that Sarah Wolfe, a psychiatrist at Western Psychiatric Institute & Clinic, arrived at her Chislett Street home after an assault on her older sister began.
Allegheny County medical examiner Karl Williams has said both women died of a single gunshot wound to the head and sustained additional injuries, which he would not describe.
Pittsburgh police found the bodies at the bottom of the stairs in the unfinished basement of their home Friday afternoon after Susan Wolfe's co-workers called 911 because they were concerned that she had not shown up for work.
Susan was naked. Sarah was clothed. Sources said a liquid was poured over at least one of the women's bodies, possibly in an effort to mask evidence. Officials have not publicly said whether either was sexually assaulted.
The house was the site of a burglary in which two televisions were taken Dec. 30, Susan's birthday. Sarah purchased the home about three weeks earlier.
While Sarah had been living in Pittsburgh for several years, her sister had only recently moved from Clinton, Iowa, where she worked as a teacher. Clinton police Chief Brian Guy said he knew of no significant police calls involving either woman while they lived in Clinton.
At a public safety meeting Tuesday night, Zone 5 police Cmdr. Tim O'Connor talked with neighbors concerned about the sisters' deaths, adding that "there is the potential that we have this perpetrator at large and in our midst." He said uniformed patrols in East Liberty and the surrounding neighborhoods have increased. He also asked residents to look out for their neighbors, families and themselves.
"I ask everybody to keep their doors and windows locked. Don't answer your door if you don't know who is out there," he said. "If you have any kind of question about who might be around your house or anything suspicious in your neighborhood, pick up the phone and call 911."
