Four people were injured and two suspects were in custody after a Halloween shooting at the University of Southern California in Los Angeles, police said.
Capt. David Carlisle of the university's Public Safety Department said Thursday the shooting happened outside the Ronald Tutor Campus Center following an argument between two men who didn't attend USC, the Los Angeles Times reported.
Witnesses said more than 100 people were outside the center, site of a party sponsored by a student organization.
Carlisle said one of the men pulled a gun and started firing at his intended target. He said the victim was critically injured and taken to a local hospital for surgery.
"You hear one shot and you're like, 'Wait, what was that?'" graduate student Matthew Hamilton, who witnessed the incident, told the Times. "As soon as it registered, everyone just ran."
Three other people also were taken to area hospitals with non-life-threatening injuries, the Times said.
Police caught the suspects, one thought to be the shooter, near the scene.
The campus was on lockdown for a brief time after the shooting.
