(Reuters) - Police killed one suspect in the Boston Marathon bombing during a shootout and were engaged in a house-to-house search for a second man on Friday in the Boston suburb of Watertown after a bloody night of shooting and explosions in the city's streets.
Authorities warned people in Watertown not to leave their homes and not to answer the door. During the night a university police officer was killed, a transit police officer was wounded, and the suspects carjacked a vehicle before leading police on a chase that ended with one suspect shot dead.
Police said the suspect they were seeking was the man shown wearing a white cap in surveillance pictures released on Thursday night which had been taken shortly before Monday's explosions that killed three people and wounded 176 at the finish of the Boston Marathon.
