Speaking on KTLA-TV, Chief Charlie Beck says Mainak Sarkar drove to Los Angeles from Minnesota with two guns and killed Professor William Klug before killing himself.

Beck says when authorities searched Sarkar’s home in Minnesota, they found a “kill list” with the names of Klug, another UCLA professor and a woman.

Beck says the woman was found shot dead in her home in a nearby Minnesota town. The other professor on the list is alright.

Beck says it appears that mental issues were involved and says Sarkar’s dispute with Klug appears to be tied to Sarkar thinking the professor released intellectual property that harmed Sarkar.

Police are asking the public’s help to find the car Sarkar drove to Los Angeles, a 2003 Nissan Sentra with the license plate of 720KTW.
