UCLA campus shooting: What we know now

The Associated Press contributed to this report.

Hundreds of heavily armed officers swarmed the sprawling UCLA campus Wednesday following a shooting that forced thousands to barricade themselves in classrooms and offices, some using belts and chairs to secure doors, until authorities determined the gunman and single victim were dead.

Authorities have identified the victim as a mechanical engineer professor. The shooter has not yet been identified and the motive was not immediately clear. Investigators have found a gun and what might be a suicide note.

William S. Klug was gunned down in an engineering building office Wednesday morning, according to the official who has knowledge of the investigation but wasn't authorized to publicly discuss it, according to The Associated Press.

Klug, a married father of two, is described as a kind, gentle person.

Classes will resume Thursday. Engineering classes will resume Monday, according to the Daily Bruin.

According to Charlie Beck, the chief of the LAPD, there is "no continuing threat to the campus" and officials are releasing students from the lockdown.

"The campus is now safe," and "the issue that has occurred has been contained," Beck said.

Beck confirmed that one of the two men found dead was the suspected shooter and that there are no suspects outstanding.

Both of the deceased men were killed via gunshot wounds in an apparent murder-suicide. A homicide investigation will ensue.

"There is no evidence to support a outstanding suspects at this point, but out of an abundance of caution we are going to continue our search of several of the buildings adjacent to the crime scene," Beck said.
