As usual, UCLA students went to school expecting to take final exams and presentations. But those were forgotten around 10 a.m. when a cellphone message in the campus, that a shooting had taken place.    

Two people were killed on Wednesday morning at the University of California, Los Angeles, this led police to lock down the campus for about two hours as officers searched and cleared the area.   

“The campus is now safe,” Charlie Beck, chief of the Los Angeles Police Department, said at a news conference Wednesday afternoon. “The issue that occurred has been contained.”

It was a murder-suicide involving two men inside an engineering building near the campus’ south side, Los Angeles Police Chief Charlie Beck said.  

Sources identified the victim as William S. Klug, 39, a father of two kids, and an associate professor of mechanical and aerospace engineering.

“I am absolutely devastated,” said Alan Garfinkel, a professor of integrative biology and physiology who worked with  professor Klug to develop a computer generated virtual heart. “You cannot ask for a nicer, gentler, sweeter and more supportive guy than William Klug.”

Fire at the city campus started at about 10 a.m. and the campus locked down of 43,000 students. Police urged people to stay in and students barricaded themselves in classrooms and federal law enforcement officials streamed in.  

Officers had not identified the gunman, and a motive was not clear. Andy Neiman, the LAPD’s  chief spokesman, confirmed a note was found at the scene, but investigators had not conformed whether the note was connected to the shooting.

Many students said they received a text messages and social media  announced that four shooters may have been roaming the campus.

”There’s a ton of information spreading over social media and group messages and it’s hard for everyone to sort out what is true and what isn’t,” Rafi Sands, vice president of UCLA’s student government, said as he hid with 30 other students inside Haines Hall during the lockdown. “They are saying there are multiple shooters, one near here.”

Kampouridis said he fled quickly and shouted at students to run. He burst out of the building and called 911, then began sending messages to friends and posting social media updates urging them to “stay away from Engineering.” He was not sure whether he saw a police officer or the gunman, but wanted to warn friends.
