Active shooter at YouTube HQ. Heard shots and saw people running while at my desk. Now barricaded inside a room with coworkers.

We were sitting in a meeting and then we heard people running because it was rumbling the floor. First thought was earthquake. https://t.co/gmolQmRXm1

Product Manager Todd Sherman live Tweeted his experience:
“First thought was earthquake. After exiting the room we still didn’t know what was going on but more people were running,” he wrote.
“Seemed serious and not like a drill. We headed towards the exit and then saw more people and someone said that there was a person with a gun. I looked down and saw blood drips on the floor and stairs. Peaked [sic] 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.”
