Intensifying the Search for Center City Suspect
After DNA tests linked the May 7, 1998, murder of Penn doctoral student Shannon Schieber to three sexual assaults in the Rittenhouse Square area since 1997, the Philadelphia Police issued a second sketch based on victims' descriptions of the suspect, and released a psychological profile by FBI expert Jim Fitzgerald. The new sketch is the nearer one at right. Authorities now believe he chooses his victims ahead of time, selecting young women he views as superior to him in status, and stalks them for up to a week before breaking into their apartments. Police think he is a nocturnal person who lives in the area, probably alone or in a household where no one questions his whereabouts between midnight and 6 a.m.; that he could be a runner or mountain climber--rail-thin and able to scale up to high windows and slip through small spaces--and that his behavior may have changed significantly in the 16 months after Ms. Schieber was murdered.
Penn has offered a $20,000 reward for information leading to his capture.
