The victim was found about 4 p.m. Friday face down in the first-floor living room of her home on the 3200 block of Mercer Street by a family member, who then called police. She was pronounced dead at the scene by medics shortly afterward.



Police on Tuesday said she was shot to death, with a gunshot wound to her head. They said that, at one point, Andrew Cruttenden had lived with his aunt, but it was not known where he was most recently residing.



The motive for the shooting is believed to have been a robbery. Police have said that the second floor of the rowhouse appeared ransacked. According to family members, some items were missing, including electronics, police said.



According to court records, Cruttenden had previously been arrested on Jan. 28, 2008, in Philadelphia. Then 17, he was charged as an adult with robbery, conspiracy, aggravated assault, possession of an instrument of crime and related offenses. He pleaded guilty to the four charges in October 2008; related charges were dropped.
