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.
Hundreds of students and faculty gathered at UCLA on Thursday night for a vigil mourning the professor who was killed on the Westwood campus by his former student.
The #BruinStrong candlelight vigil was held at Bruin Plaza and coincided with the commemoration of National Gun Violence Awareness Day.
Many held blue and yellow battery-powered candles as they paid tribute to William Klug, the 39-year-old mechanical and aerospace engineering professor who was gunned down in the university's engineering building.
The widow of slain UCLA professor William Klug issued a statement on Thursday, asking the public and the media to respect her family's privacy as they grieve:
“During this extremely difficult time for our family, we are grateful for the tremendous outpouring of support. This is an indescribable loss," Mary Elise Klug said in her statement, which was distributed by the university.
"Bill was so much more than my soul mate. I will miss him every day for the rest of my life. Knowing that so many others share our family’s sorrow has provided a measure of comfort.
Two vigils will be held on the UCLA campus this week as the community gathers after Wednesday's murder-suicide.
A #BruinStrong candlelight vigil has been planned for 8:30 p.m. on Thursday at Bruin Plaza. Student organizers are urging people to show their solidarity on National Gun Violence Awareness Day.
"I call upon the Bruin family and community members across the state and nation to come together during this difficult time," said Danny Siegel, president of the Undergraduate Students Assn. Los Angeles City Councilman Paul Koretz and interfaith leaders are expected to attend.
