911 calls released in UCLA shooting

WESTWOOD, LOS ANGELES (KABC) -- It was a day of terror at UCLA. On June 1, the campus went on lockdown as hundreds of officers descended on Westwood for what was believed to be an active shooter on the loose.

The incident turned out to be a murder-suicide, with no active shooter on campus.

But recordings of 911 calls just released described the frantic minutes after the two bodies were discovered in an engineering building.

An early call indicates the incident was being called an active shooter, with no known location for the suspect.

On the recordings, a 911 operators cautions that "it's going to be the whole world coming" to the campus.

That was virtually the case. A massive law enforcement presence came to UCLA, including police, sheriff's deputies, SWAT officers, the FBI and ATF.

In the end, the shooter was identified as Mainak Sarkar, a former student who had driven from Minnesota to kill his former professor William Klug, as well as another professor whom he was unable to locate.

He then turned the gun on himself, officials said.

Investigators later discovered he had also killed his estranged wife in Minnesota before heading to Los Angeles.
