Mainak Sarkar shot William S. Klug, his former professor, and then committed suicide in an engineering building at UCLA on Wednesday morning, Los Angeles police say.
Sarkar, who came to UCLA armed with two pistols and extra ammunition, had accused Klug of stealing his computer code and giving it to someone else, the LAPD said.
Sarkar, 38, lived in Minnesota and appears also to have killed a woman in a small town in that state. Police have not identified the woman found shot to death in Brooklyn Park, Minn., but Ashley Hasti, who married Sarkar in 2011, is listed as the resident of the home in which the body was found.
Sarkar left a note at the UCLA shooting scene, which led police to his St. Paul, Minn. home, where they found a "kill list" bearing the Minnesota victim's name, along with Klug's and that of another UCLA professor, LAPD Chief Charlie Beck said.
Klug, 39, was a professor of mechanical and aerospace engineering.
The second UCLA professor on Sarkar's list has not been named. He is safe.
UCLA classes -- except for those in engineering -- resumed Thursday.
