Upper Darby Police Superintendent Michael Chitwood said yesterday that the investigation into the body of a newborn found in a car trunk in Drexel Hill on Jan. 22 is on hold until the medical examiner issues a final report.

Chitwood said testing is being done to determine whether the 5- to 6-pound baby was alive when he was born. If the baby was stillborn, the mother still faces charges such as desecration of a corpse, Chitwood said.

He said police believe the woman who gave birth is an 18-year-old Drexel University freshman, the granddaughter of Albert E. Piscopo, 62, who is president and chief executive of the Glenmede Trust Co. - Kathleen Brady Shea
