LOS ANGELES - A murder-suicide killed two people at the University of California, Los Angeles on Wednesday, shutting down the campus for two hours as officers in camouflage and tactical gear responded to reports of a shooting.

"A homicide and a suicide occurred," Los Angeles Police Chief Charlie Beck told reporters near the scene, saying a gun was recovered at the scene.

"It appears to be entirely contained," he said. "There are no suspects outstanding and no continuing threat to UCLA's campus."

Both victims were males, officials said, without offering further details.

The shooting created a stir as police approached the scene fearing the shooter might still be active and university officials ordered the campus locked down.

At least three city blocks leading into the campus were filled with dozens of emergency vehicles. Officers in camouflage uniforms with rifles, bulletproof vests and helmets surrounded the area of the shooting.

An armored car was parked in the middle of one intersection, and helicopters clattered overhead.

Students and other bystanders stood calmly, taking pictures on their cell phones and watching the emergency workers.
