The suspect in the shooting of a UCLA professor has been named as PhD candidate Mainak Sarkar. The victim was Professor William Klug. He was a teacher in Mechanical and Aerospace Engineering, according to his official bio on the school’s website. Sarkar was first named in a report by CBS News. He was a native of Minneapolis and had a PhD in solid mechanics from UCLA. The shooting prompted a two-hour lockdown at the school with LAPD Charlie Beck telling the media when it was over, “The campus is entirely contained. We believe there are no suspects outstanding and no continuing threat to UCLA’s campus.” William Scott Klug was 39 years old. Keep reading…

Everipedia notes that his hatred of Klug, that Sarkar is Muslim from India.

A note was also allegedly found from the killer, the contents of which have not yet been revealed.

UPDATE:

The note said to take care of his cat at his house in Minnesota, it was there they found the ‘kill list’, and then found the dead woman because she was on the kill list.

The former UCLA doctoral student who killed a professor in an apparent murder-suicide had a “kill list” that included the name of a woman found dead in Minnesota, as well as that of another UCLA instructor, the Los Angeles police chief said. Chief Charlie Beck told the KTLA television station that a victim was found shot to death in Minnesota after authorities found information in notes left by Mainak Sarkar that led them to her. “That person was shot,” Beck said. “The connection is very strong. We still have to do the various ballistic tests … but it’s very strong.” Beck said police believe Sarkar, a 2013 Ph.D. graduate of UCLA’s engineering school who most recently lived in Minnesota, packed two handguns, multiple rounds of ammunition, and several magazines in a backpack and drove from his house to Los Angeles. He then went to the UCLA campus, marched into the fourth floor office of his former professor William Klug, and fired multiple rounds at Klug before killing himself, Beck said. Keep reading…

They have not named the woman found dead yet, but Everipedia notes he had broken up with a girlfriend who lived in Minnesota.

Update:

Person dead is the ex-girlfriend, Ashley Hasti.

Everipedia listing has now changed Sarkar’s religion to Hindu. We got the screenshot noting Muslim before most had found the site, immediately after the name was announced. We will try to clarify that point.
