Boston marathon 'bomber' captured

The teenage suspect in the Boston Marathon bombings is in custody after being found hiding in a boat in a suburban homeowner's backyard. Police said they exchanged gunfire with Dzhokhar Tsarnaev, 19, after cornering him in Watertown, near Boston. He had escaped on foot early on Friday, apparently wounded, after a police shootout that claimed the life of his elder brother, an alleged accomplice. Three people died and more than 170 were hurt in Monday's bombings.
