A woman has injured three people, before killing herself, when she opened fire at YouTube headquarters in California.
A 36-year-old victim, believed to be the shooter’s boyfriend, leapt off the scene in a critical condition. The other two wounded were two women, aged 32 and 27. Staff members said they ran away from gunshots and barricaded themselves inside rooms to escape.
A staffer, Todd Sherman recounted: "We were sitting in a meeting and then we heard people running because it was rumbling the floor. First thought was earthquake.
"We headed towards the exit and then saw more people and someone said that there was a person with a gun. Shit.
"I looked down and saw blood drips on the floor and stairs. Peaked around for threats and then we headed downstairs and out the front.
"Police cruisers pull up, hopped out with rifles ready and I told them where the situation was as I headed down the street to meet up with a couple team members."
