12:53 p.m.
Officers searching the building found the suspect dead from an apparent self-inflicted gunshot wound, Jackson said.
The aftermath
The shooting left four victims hospitalized: three with gunshot wounds and one with an ankle injury from running from the scene, police said.
Meanwhile, officers worked to clear the scene. They patted down the fleeing YouTube employees and conducted a room-by-room search. Authorities later said there was no immediate threat to the community.

PHOTO: Police search a building at YouTube's corporate headquarters as an active shooter situation was underway in San Bruno, Calif., April 3, 2018.
Aghdam appears to have carried out the shooting because she was \"upset\" with YouTube's \"policies and practices,\" authorities said today.
There's no evidence linking her to anyone at the scene, San Bruno police said.
A handgun was found at scene and police said Aghdam legally possessed and owned the weapon. It was unclear where it was purchased.
\"There are no words to describe how horrible it was to have an active shooter today,\" YouTube CEO Susan Wojcicki tweeted on Tuesday.
\"Our deepest gratitude to law enforcement & first responders for their rapid response,\" she said. \"Our hearts go out to all those injured & impacted today. We will come together to heal as a family.\"
