Officials at Jackson State University in Mississippi locked down the campus for roughly 30 minutes on Wednesday after a nearby shooting wounded one person in the leg, a university spokesman said. 'The shutdown has been lifted,' spokesman L.A. Warren said. The injured person was taken to a hospital and police were searching for a suspect who fled in a black car, Warren said. 'The campus community is no longer under threat of an active shooter,' the school, a historically black university, posted on Twitter. The shooting took place on a block at the edge of the campus, the Jackson Police Department said.
