Mainak Sarkar

A gunman who killed a professor at the University of California, Los Angeles (UCLA), yesterday has been identified as former doctoral student Mainak Sarkar, 38, who graduated from IIT Kharagpur in aerospace engineering in 2000.

Sarkar shot himself after killing William Klug, 39, under whom he had completed his PhD in mechanical engineering in 2013 and whom he accused of stealing his computer code and giving it to someone else, the Los Angeles Times reported.

He is also believed to have murdered a woman, whom Everipedia described as his ex-girlfriend, at her home in Brooklyn Park, Minnesota, shortly before killing Klug. Police found a "kill list" at Sarkar's Minnesota home, indicating he had a few more targets.

IIT Kharagpur officials and alumni association leaders said they could not readily recall whether Sarkar was a student there.

The alumni list of the aerospace engineering department on the IIT Kharagpur website does mention one Manik Sarkar from the 2000 batch. Sarkar's Facebook page too features a group photograph taken in front of the aerospace engineering department.

On March 10, Sarkar had written a blog calling Klug, associate professor of mechanical and aerospace engineering, "a very sick person" who should not be trusted.

"William 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,"

Sarkar wrote, posting a picture of Klug.

"My name is Mainak Sarkar. I was this guy's PhD student. We had personal differences. He cleverly stole all my code and gave it (to) another student. He made me really sick.. Your enemy is your enemy. But your friend can do a lot more harm. Be careful about whom you trust. Stay away from this sick guy."
