And if you're just joining us we've been listening to the chief of police of the San brutal police department any updating the news media on that shooting at YouTube headquarters in San Bruno the biggest headline they came out of that news conference to shooter who is now deceased. Is a female which is very big you know one would appear Thomas or senior justice correspondent. Who's been tracking the developments in Pierre the headline out of this so far one victim believed to be the shooter. Debt with a self inflicted gunshot wound but that shooter is a woman something we have. Not seen in a very long time definitely not the last year as some of these major shootings across the country. Is exactly right Tom plea saying that they encountered a very chaotic situation. Did encounter a deceased woman. On the floor at the YouTube headquarters apparently from a self inflicted gunshot wound that's why they think that this person is a shooter. As you said extremely rare to have a female shooter in these circumstances last year the Secret Service did a study of a roughly 28. Sus mass shooting incidents. All the perpetrators were male. Sort of bring in now one of our analysts and former FBI agent who studies mash shootings Brad Garrett Brad you heard the news conference their break it down force we know that the shooter apparently is dead. A female. Three to four other victims with gunshot wounds as well this happened at 1246. On the West Coast during a lunch time. YouTube was sprawling campus they were Austrian Bruno seventeen under employees. Possibly targeting the lunch hour what did you make from other things the the police chief told us well. That you have basically for people hospitalized and it did shooters so the real question Tom here is motive. Did the shooter go there to shoot a particular person during the lunch hour and then take their own lives and other people this happened to get shot. That remains to be seen so that you know the real key is motive. In is there anybody else connected to her. Now Brad. The target cure or the place where this happened YouTube headquarters which is owned by Google. Would what does that mean could this have no connection whatsoever or could have a huge connection because of all the people that log onto YouTube every single day and or use Google. That this goes Tom from personal and garnered issued an individual. Two I hate Google and he YouTube I don't like something on YouTube it's really hard to say at this point. And to we have more information. But you know you sort of have to function in what do we know about this woman. And does she have connections. Or has she sent out other and other people are other pieces of information that would suggest. That this is bigger than just her.
