to go back in if they develop new evidence that he has returned. what they said at the news conference is that his ties are to the watertown area and they do not believe he has any vehicle of his own. they believe he is still in the immediate vicinity. they also indicated that they have had several leads into other parts of massachusetts but at this point, that has washed out. and i think most significantly when asked how they got to these guys, they indicated that by releasing the pictures 24 hours ago and we talked about this on your broadcast last night it can have the effect of forcing them to move or to flee to act in some way that draws attention to themselves. that appears to be what the tipoff may have been, bret. bret: catherine, very quickly. what i don t understand yet is how after this fire fight and the bomb throwing, the pipe bombs and the homemade grenades and exchange with police how dzhokhar tsarnaev escapes? how does he get out of that

somewhat to that we retrieved a surveillance video of the 7/11. they were not involved in the armed robbery of that convenience store. do you believe the suspects are still and you can talk about any interaction at mit? no. i don t want to comment on that because that is a homicide investigation. all of this individual s ties were here in massachusetts. we believe that s the only person we are looking for at this time. do you believe he is still in massachusetts? or in watertown? yes, i believe he is still in massachusetts. giving 20 extra troopers to watertown for the weekend. that is the case. no. the whole point in providing that extra cover to watertown is for the benefit of this community. we have had this whole community, in fact, the greater boston area as you know shut down today. but, in particular. these folks had a shooting in their neighborhood last night. there was a loss of life up there it was very violent activity.
obviously they have come up with nothing at this point. there is only one person they are looking for. if they have got him it would end, bret. bret: mike tobin there live on the scene. we can see the principles of this news conference arriving there about ready to brief at the microphones. we can tell you it has been a long day for these officers going door to door and for the people of watertown as they have shut down, told to stay in their homes. some people this morning went to work. they were told to get back home if they could. and stay there. there you see governor devol patrick. he will start this news conference as he has. thank you all for your patience. doing the checks here. thank you all for your patience. bret: we will hear from the boston mayor and massachusetts state police superintendent and the watertown police chief as well. we expect to get an update of where this investigation
