UCLA shooter Mainak Sarkar was heavily armed and planned to kill another professor, said Los Angeles Police Chief Charlie Beck on June 2, a day after the murder-suicide.
Sarkar shot and killed mechanical engineering professor William Klug in an office before turning the gun on himself.
Sarkar, 38, was a former doctoral student at UCLA and had graduated in 2013.
The shooting led to a lockdown at the UCLA campus with a huge police response until authorities determined there was no continuing threat.
Beck said the shooter was heavily armed and had on him two semi-automatic pistols and multiple magazines of ammunition.
The LAPD says it is known yet whether Sarkar specifically went to UCLA to target only the professors, or if he planned a mass murder at the university.
However, Beck says that based on the weapons Sarkar had on him he “could’ve caused many more fatalities.”
Sarkar also had a note on him that said, “Please check on my cat.”
Officials went to Sarkar’s home in Minnesota, the state where he had been living for years. In the residence they found a “kill list” which included Klug, another professor, and a woman.
Police went to go check on the woman but found her dead, Beck said. The motive for the murder of the woman is not yet known.
The other professor, who was on the “kill list” was notified that he was being targeted by the shooter. The professor, whose name was not released, said he knew Sarkar “had issues with him,” Beck said in the press conference. The second professor was not on campus during the time of the shooting.
Officials believe Sarkar murdered the woman in Minnesota and then traveled to California to kill Klug. Police also said Sarkar killed himself immediately after shooting Klug.
Authorities are now investigating the incident by looking at surveillance videos and interviewing witnesses. They say they received multiple 911 calls after people heard three rounds of gunfire.
Authorities are also searching for the shooter’s vehicle, a 2003 gray Nissan Sentra, where more evidence may be found.
Sarkar legally purchased a gun used in the shooting and it was registered to him.
The shooter had lashed out on Klug on social media for months. On March 10, Sarkar called Klug 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. “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,” said Sarkar, according to the Los Angeles Times.

However, in his 2013 doctoral dissertation, the shooter was grateful for Klug’s help and support.
A syllabus from 2010 shows Sarkar as one of two teaching assistants in a mechanical and aerospace engineering course, MAE: 101: Statics and Strength of Materials.
Sarkar was listed in the 2014 doctoral commencement booklet with the vicitm as his advisor.
“Thank you for being my mentor,” Sarkar wrote.
Those who knew the professor said he was a kind and patients person with no indication that he had problems with anyone.
Klug was a married father of two, according to officials and friends.
