Authorities haveĀ identified the UCLA gunman in the murder-suicide on campus Wednesday as Mainak Sarkar, a former doctoral student who accused his victim of stealing his computer code and giving it to someone else, the Los Angeles Times reports.

Sarkar reportedly killed himself after fatally shooting 39-year-old UCLA professor William Klug in Engineering Building 4.

Klug, an associate professor of mechanical and aerospace engineering, had reportedly been the subject of several angry posts by Sarkar on social media. According to the report, on March 10 Sakar called Klug a ā€œvery sick personā€ who should not be trusted.

ā€œWilliam Klug, UCLA professor is not the kind of person when you think of a professor. He is a very sick person. I urge every new student coming to UCLA to stay away from this guy,ā€ Sarkar wrote, according to the Times. ā€œHe made me really sick. Your enemy is my enemy. But your friend can do a lot more harm. Be careful about whom you trust.ā€

A university spokesperson refuted Sarkarā€™s comments as ā€œabsolutely untrue.ā€

ā€œThe idea that somebody took his ideas is absolutely psychotic,ā€ the source said, adding that Klug went above and beyond to help Sarkar finish his dissertation and graduate, even though the quality of his work was not up to par.


ā€œBill was a super nice guy,ā€ the source said. ā€œHe didnā€™t want to hurt the guy.ā€

In the doctoral dissertation submitted in 2013, Sarkar thanked KlugĀ for his help and support.

It was later reported that the gunman had a ā€œkill list,ā€ which police found in his Minnesota home, CNN reports. Klugā€™s name was on the list, as was the name of a woman whom police found dead, Los Angeles Police Chief Charlie Beck confirmed.


ā€œWe did a follow-up investigation to that femaleā€™s residence in a nearby town in Minnesota and found her deceased by gunshot wound,ā€ Beck said.
