Officers were called to the building late Tuesday morning in the Strawberry Mansion neighborhood in north Philadelphia after neighbors reported a foul odor.
A police spokeswoman says officers found two bodies stored in boxes and a third body in a casket.
Police say the building was apparently owned by the Powell Funeral Home around the corner. Police say the funeral home "was aware of the bodies that were there."
Numbers for the funeral home and Powell Mortuary Services are disconnected. Websites associated with the company are no longer active.
