(CBS/AP) PITTSBURGH - The medical examiner's office says the gunman who shot seven people and was killed Thursday in an attack on the University of Pittsburgh psychiatric clinic wasn't carrying identification and his fingerprints have yielded no clues to his identity.
The gunman's fingerprints were run through a nationwide database used by police and federal agencies, but to no avail. City police have yet to say what motivated the gunman, who was apparently shot dead by campus police in the rampage.
Authorities say the man, armed with two semiautomatic handguns, entered the clinic lobby yesterday afternoon and opened fire, shooting seven people - one of whom died and whose name has yet to be released. An eighth person was hurt, but officials say that injury was not gunshot-related.
The Western Psychiatric Institute and Clinic was open Friday with police and extra security checking employee and visitors' identification.
