A 22-year-old Temple University student shot and killed another student Thursday night in North Philadelphia after what police believe might have been an argument over drugs, university and police officials said.

The suspected shooter was arrested at the scene – a short distance from the university's main campus. Investigators say they recovered two guns and a bag of drugs.

An eight-foot-deep crater that marked the spot where a medevac plane crashed into the ground, killing seven people and injuring dozens more, was filled in.
