Philadelphia police said they discovered a 20-year-old woman wedged between the wall of a Catholic school and a trailer after nuns reported screams.

Officers said the woman apparently became wedged between the exterior wall of the Visitation of the Blessed Virgin Mary School and a trailer used as a spare classroom after falling from the roof of the school, the Philadelphia Daily News reported Monday.

Sgt. Shawn Gushue said firefighters worked for about an hour using the Jaws of Life to slice through the wall of the trailer and free the woman, whose name was not released.

Gushue said the woman was taken to Episcopal Hospital to receive treatment for cuts and bruises. He said the woman told authorities that she had been raped.

A priest at the school said the woman did not attend services at the facility. He said her reason for being on the roof is "the 64 million-dollar question."
