San Francisco General Hospital has reported that it is receiving "multiple patients" from the site of the shooting at the 200,000-square-foot facility where 1,700 people are employed. Stanford University Medical Center has also reported to Fox News that it has received "four to five" patients from the site of the incident. Neither hospital gave any details on the condition of their patients, nor did they confirm the nature of the injuries those patients have sustained. Google, which owns YouTube, responded to the situation on Twitter, saying that they're working with authorities.

"Re: YouTube situation, we are coordinating with authorities and will provide official information here from Google and YouTube as it becomes available."

Vadim Lavrusik, who works for YouTube, was present on the scene and took to Twitter saying, "Active shooter at YouTube HQ. Heard shots and saw people running while at my desk. Now barricaded inside a room with coworkers. Safe. Got evacuated it. Outside now." According to local KRON4, a woman shot her boyfriend, but that has yet to be confirmed by authorities on site. City Manager Connie Jackson has received multiple 911 calls from YouTube reporting a shooting. Another witness told CNN she saw one person shot on the patio where they eat.

In a thread on Twitter, YouTube product manager Todd Sherman relayed his account of the situation. At the end of the thread, he revealed that he was in an Uber and on his way home safe, but not before revealing he saw blood on the floor and stairs. Here's what he had to say.

"We were sitting in a meeting and then we heard people running because it was rumbling the floor. First thought was earthquake. After existing the room we still didn't know what was going on but more people were running. 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. Shit. At that point every new person I saw was a potential shooter. Someone else said that the person shot out the back doors and then shot themselves. 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."

Employees of YouTube could be seen exiting the building with their hands above their heads. At the time of this writing, authorities have not revealed any details on the possible shooter. This news comes to us courtesy of Deadline. You can see tweets from those who were on site for yourself below.
