PHILADELPHIA (AP) -- Philadelphia police say a 17-year-old who shot two classmates got the gun only moments before from an ex-student who bypassed metal detectors as a "guest."
Officials say video footage shows the former student, 18-year-old Donte Walker, handing off the gun and exchanging money with an unidentified male. They say the gun then was passed to Raisheem Rochwell, who feared he was going to be targeted in an after-school assault.
Rochwell is charged with shooting two students in the arm Friday in the Delaware Valley Charter High School gymnasium. Police believe the victims were struck by the same bullet. Both have been treated and released.
Rochwell is being held on aggravated assault and other charges. His lawyer says he will be vindicated.
It's not immediately clear if Walker has a lawyer.
