Update: Police have identified the gunman as graduate student Mainak Sarkar, who had received his PhD in from UCLA in mechanical engineering. He has previously blogged about his hatred for Klug, calling him a "sick person."
Sarkar also reportedly possessed a "kill list" police found in his residence in Minnesota. This list included his ex-wife, Ashley Hasti—a 31-year-old medical student at the University of Minnesota, whom Sarkar killed in her Minnesota home before heading to UCLA to target Klug.
University of California, Los Angeles students were taking their end-of-the year exams when the entire school went into a lockdown Wednesday following a deadly shooting in an engineering building.
Amid the chaos, the students barricaded themselves in their rooms to keep safe. After several hours, police determined the shooting was a murder-suicide involving a student gunman and a professor.
UCLA and law enforcement officials identified the victim as professor William Klug, a teacher of mechanical and aerospace engineering. The shooter, who was a reportedly his student, turned the gun on himself after fatally shooting the teacher. They were both pronounced dead at the scene.
The incident occurred shortly before 10 a.m. Wednesday morning. No one else was shot.
“I’m just outraged,” a student who knew Klug told KNBC. “I’m mad that someone would do that to a young professor who just started his career at UCLA. It’s just a shame.”
Klug, who lived in El Segundo with his wife and two kids, also coached his son’s Little League team. As the L.A. Times reports, the 39-year-old loved surfing and frequented Los Angeles Dodgers games. He specialized in computational mechanics and earned his undergraduate degree in engineering physics from Westmont College in 1997, his master’s degree in civil engineering at UCLA in 1999, and his Ph.D. in mechanical engineering from Caltech in 2003.
The police have not released the name of the shooter, who was believed to be upset about a grade the professor had given him.
“I am absolutely devastated,” said Alan Garfinkel, a professor of integrative biology and physiology who worked with Klug. “You cannot ask for a nicer, gentler, sweeter and more supportive guy than William Klug.”
Alongside a gun, a note was also found at the crime scene, but its contents have not yet been made public. It is not also clear if it is indeed related to the murder-suicide.
“There is evidence that there could be a suicide note, but we do not know that,” Los Angeles Police Chief Charlie Beck said.

Following the tragic incident, UCLA has canceled all engineering classes for the rest of the week.
“The campus remains in a state of sorrow over the tragic shooting and loss of two members of the Bruin community this morning,” said executive Vice Chancellor and Provost Scott L. Waugh. “We’re trying to restore the campus to order as quickly as possible.”
