STILLWATER â€” A growing number of Oklahoma State University students want to carry concealed weapons on campus, said the state director of a campus pro-gun group.

Just hours before an OSU student was shot and robbed Monday at his off-campus residence, members of the university's chapter of Students for Concealed Carry on Campus stood outside of the main library passing out fliers advocating self-defense on campus, said Adrienne O'Reilly, state director.
