Two people were killed in a shooting on the UCLA campus on Wednesday morning in a “possible murder-suicide,” police said. The campus was on lockdown, with many staying in place out of fear that a shooter might still be at large. The LAPD pronounced the incident over around 12 p.m. local time.

“It’s certainly possible that one of the victims is the shooter,” UCLA campus police Chief James Harren told reporters at the scene. He had no further information on the two dead. He added that police would take the shooter into custody “if there is an outstanding suspect.”

There were still “dozens of people sheltered in place” nearly two hours after the shooting, Harren said.

Officers in tactical gear were seen entering Boelter Hall, which is part of the school of engineering. LAPD bomb squad members were also on the scene. Police were advising students to avoid the area.

“Police are investigating a shooting in Engineering IV. Police are on the scene and report that there are two victims. The campus remains on lockdown,” said a statement on the school’s press site. “People are being asked to shelter in place.”
