Two men are dead following a murder-suicide on the University of California Los Angeles (UCLA) campus.
William S. Klug, a professor of mechanical engineering, was gunned down in an engineering building office, according to a law enforcement official.
The other man, whose body was found in the same area, has yet to be identified.
LAPD Chief Charlie Beck said a note was found near the bodies.
“I don’t know if it’s a suicide note, I don’t know if it’s a confession, I don’t know what it is,” said Beck.
The bodies were found in a small office, Beck confirmed, and a gun was found in close proximity.
All classes were cancelled for the day and are expected to resume Thursday.
The school urged students to “go to a secure location and deny entry (lockdown)” after the shooting in an engineering building on campus.
The school is in its final weeks of classes for the term, with finals set to begin next week.
Both campus police and the LAPD responded to multiple reports of shots fired.
Helicopter footage from NBC Los Angeles showed police tactical officers running towards the entrance of the science building.
Dozens of emergency vehicles were on scene as well as SWAT teams; a bomb squad was on campus as a precautionary measure.
A UCLA student told CBS News that police stormed the building amid reports of a shooting.
“One of my friends was in Boelter, in class and she said a bunch of police with like machine guns came and told them to just run,” the student told the news station in a phone interview.
