COOPER: We have an update now on the shooting at YouTube headquarters south of San Francisco. Dan Simon joins us now from San Bruno, California. So, Dan, what's the latest on what happened today?</s>DAN SIMON, CNN CORRESPONDENT: Well, Anderson, what a frightening and chaotic situation for those YouTube employees when the shooting broke out. This is happening just before 1:00 p.m. local time. Police arriving moments later. When they arrived, they did find one shooting victim at the front of the headquarters and then as they searched the entire headquarters, they did find the woman dead of a self-inflicted gunshot wound. That is the shooter. Then, according to police, they found a couple more shooting victims at some adjacent businesses, one of whom had gone to the Carl's Jr. Restaurant that is just next to YouTube. She went there apparently to try to get some medical attention. We know some employees there tried to help her and then ambulances arrived and took her to the hospital. I can tell you, as for the three shooting victims, their conditions range from fair to critical. But the good news is according to the trauma surgeon at the hospital, all of them appeared to be alert and talking and were aware of what happened, Anderson.</s>COOPER: And is there anything known about the motive at this point, that police are saying?</s>SIMON: Police not saying what they think the motive is. They are saying, at least law enforcement officials telling CNN that the shooter apparently did know at least one of the victims. Ultimately, what that connection is, we don't know. We don't know what her connection is to YouTube, either. But, of course, one of the things that investigators will be looking at is whether or not this may have been some kind of domestic situation, Anderson.</s>COOPER: Dan Simon, I appreciate the reporting. Thanks. We'll be right back.
