LOS ANGELES - The man suspected in an apparent murder-suicide at UCLA had a "kill list," and a second victim on the list has been found dead in Minnesota, a representative with the Los Angeles Police Department told KTLA Thursday.
Mainak Sarkar was the shooter, the Los Angeles Police Department said Thursday. Authorities haven't released additional information about Sarkar, who allegedly shot and killed a professor Wednesday in one of the university's engineering buildings before turning the gun on himself.
The shooting stemmed from a student-teacher dispute, police sources told CNN.
Professor William S. Klug was identified by UCLA Student Body President Michael Skiles as the victim.
Sarkar is listed on a website for Klug's research group at UCLA, and an online abstract of his dissertation lists Klug as his adviser.
The police chief said "a dispute over intellectual property" was tied to the UCLA shooting.
Gunman Mainak Sarkar felt the professor he killed had released information "that harmed him," Beck said. "UCLA says this is absolutely not true. This is the workings of his imagination," the police chief said.
Nearly three months prior to the deadly shooting, Sarkar took to social media to post a tirade about his former professor, the Los Angeles Times reported.
“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 in post dated March 10. “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.”
Suspect had a 'kill list'
According to KFOR's sister station KTLA, based on a note found at the crime scene, authorities performed a follow-up investigation at the former UCLA Ph.D student’s residence in Minnesota, where they found an alleged “kill list” with multiple names on it.
“Professor Klug’s name was on that list, as was another UCLA professor who was alright,” Los Angeles Police Department's Charlie Beck told KTLA.
He declined to give the professor’s name.
A female’s name was also on the list, prompting investigators to go to her home in a nearby town in Minnesota.
The unidentified victim was found deceased by gunshot wound at the residence, Beck said.
Sarkar drove from Minnesota to Los Angeles area with two handguns, multiple round of ammunition and several magazines in a backpack, according to the LAPD chief.
He entered the UCLA campus, went to the fourth floor office of Klug and shot his former professor dead with multiple rounds, Beck said.
The weapons are believed to have been purchased legally in Minnesota.
'Our hearts are heavy'
Klug was described as an easy-going Little League coach, according to one friend, and an "an empathetic, brilliant teacher" as California Lt. Gov. Gavin Newsom put it.
Klug's friend fought back tears as he described the father of two to CNN affiliate KCBS.
"It's hard to even fathom," Lance Giroux said. "To have your son grow up without a dad, it's rough."
The professor was a proud coach of his young son's baseball team, friends told KCBS.
"[He was] always very positive. Kids loved working with him because he was such an easy coach to work with," Giroux said.
The shooting shocked the student body and sent the school into lockdown mode for hours.
"Our hearts are heavy this evening as our campus family mourns the sudden and tragic deaths of two people on our campus earlier today," said Chancellor Gene Block in an email Wednesday. "Our UCLA family has indeed been shaken, but we will rely upon the strong bonds of our community and our faith in one another as we begin the process of healing."
The Los Angeles Police Department said it got the call about the shooting around 10 a.m. local time.
Officials put the campus on lockdown as authorities investigated. Throngs of police with long guns patrolled the streets of the campus of more than 40,000 students.
SWAT officers and dozens of squad cars filled the area as police tried to clear campus buildings floor by floor -- a task that CNN law enforcement analyst Tom Fuentes called "monumental."
UCLA's engineering building is in the middle of a very densely populated part of Los Angeles.
The situation was contained shortly after noon, LAPD Chief Charlie Beck said. He said the shooting took place in a small office in the engineering building.
Police are still investigating the shooting, according to university officials.
It was a jarring, tense time for the university's students. To protect themselves, some blocked doors with printers, according to a picture on Twitter.
Freshman Teddi Mattox said she was in a cafeteria getting breakfast along with about 100 other students when the shooting occurred.
"We got the alert and a woman said, 'This is not a joke, everyone get to the back of the dining hall because we have to stay away from the windows,'" she said.
"We're crowded back here, we've been here for at least an hour and a half. People are crying, they're nervous, they're shaking ... I have not stopped shaking for the last hour and a half."
UCLA officials said they will review all campus safety procedures.
"We're pleased in the way notification went out, troubled by some reports of unlocked doors, but we want to review everything," said Scott Waugh, UCLA's executive vice chancellor and provost.
UCLA has also extended counseling services over the next few days to serve all the students who may be in need, Waugh said.
The university's final exams are scheduled for next week, with graduation set for Friday.
The engineering school's senior class dinner was scheduled for Thursday night.
Classes are expected to resume for most of the university Thursday. At the engineering school, where the shooting occurred, classes will resume Monday, officials said.
Professor studied 'interface' of mechanics, biology
Klug is listed as a professor of mechanical and aerospace engineering on UCLA's website. He received his undergraduate degree at Westmont College, then obtained a Masters at UCLA and a Ph.D. from Caltech.
He also led the Klug Research Group, which studied "problems at the interface of mechanics and biology."
"We aim to understand how the physical properties of biological structures and materials are involved in biological function from molecular and cellular scales upward," the group's website says.
