PHILADELPHIA (UPI) -- Police said a human skull was found inside an
apartment that had recently been vacated by a group of seven
University of Pennsylvania students.
Philadelphia police said an assistant manager of the apartment
building found the skull on the kitchen counter after the students had
left, WCAU-TV, Philadelphia, reported Wednesday.
Investigators said they do not know which of the students left the
skull behind and thus far there is no indication that a crime has been
committed.
Lt. Frank Vanore said the discovery makes "kind of a weird story,"
even for the Philadelphia police. He said the skull may have been used
as a learning tool for a medical student or it may have been
purposefully left in the kitchen as a prank.
Jeff Moran, a spokesman for the Philadelphia Medical Examiner's
Office, said the skull will be analyzed by a forensic anthropologist.
