ticktock. that stolen s.u.v., it was the police who picked up the scent at that point and a police trail followed. at that point the suspect opened fire at watertown police and a transit police officer who was shot, that officer now listed in critical condition at a boston area hospital this morning. we hope he makes it. but we have not been given an indication as to whether or not he will. at another hospital, suspect number one, after the shootout on the shrapnel in the street, he was brought to the hospital, apparently died there. this is suspect number one, screen right, with the dark hat. suspect number two on the run, screen left with the white hat. police talked about that in watertown just two hours ago. >> calling on the watertown community to be calm during this time. we are talking about the east watertown, dexter, laurel street, school street area to remain in your homes. as the colonel said we're going to be doing a search.
