Facebook employee leaps to death from roof of corporate headquarters.

Daily Mail: Facebook employee jumps to his death from roof of company's Silicon Valley headquarters in apparent suicide.

A Facebook employee has died at the company's headquarters campus in Silicon Valley in what police call an apparent suicide.

Horrified bystanders in Menlo Park, California called 911 at about 11.30am on Thursday after an adult male jumped from the top of a four-story building on the 100 block of Jefferson Drive.

Paramedics rushed to Facebook's sprawling campus and rendered first aid, but the victim was declared dead on the scene.

The deceased individual has not been publicly identified pending family notification, but Facebook confirmed in a statement to DailyMail.com that he was an employee.

Zuckerberg may have to install suicide nets like Apple did in China to prevent employees from leaping to their deaths.

"Our AI wasn't programmed to identify suicidal tendencies."
