Mainak Sarkar, who killed a professor and himself on the campus of UCLA Wednesday, had a "kill list" that included the name of the professor and a woman who was found shot to death in Minnesota, LAPD Chief Charlie Beck said.

"We did a follow-up investigation to that female's residence in a nearby town in Minnesota and found her deceased by gunshot wound," Beck said.

Police identified the murdered professor as William S. Klug, 39. Another professor's name was on Sarkar's list, as well.

Sarkar, 38, is a Minnesota native and 2013 Ph.D. graduate of UCLA. He was living in Minnesota but drove to Los Angeles to kill Klug, with whom he had a dispute regarding intellectual property.

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

However, in his 2013 doctoral dissertation, Sarkar thanked Klug "for being my mentor." A 2014 doctoral commencement booklet lists Klug as Sarkar's advisor.

"Bill was extremely generous to this student, who was a subpar student," a source said. "He helped him out and interceded for him academically."

At the scene of the UCLA shooting, Klug's office in an engineering building, investigators found a note from Sarkar, asking them to check on his cat in Minnesota.

"The note at UCLA said to ask for the finder to check on his cat in Minnesota. So we checked in (on) his cat in Minnesota at his residence. Actually we did a search warrant at his residence," Beck said.

That's where the "kill list" was found, the police chief said.

Authorities are not releasing the name of the Minnesota victim or the other professor on the list, whom they said is unharmed.

Meanwhile, police are looking for a gray 2003 Nissan Sentra which Sarkar drove from Minnesota to L.A. Inside the vehicle, "there will be evidence that will help us unravel this," Beck said.
