It's over. Nearly 22 hours after the shooting of an MIT police officer led authorities on a wild manhunt for the missing alleged Boston Marathon bomber Dzhokhar Tsarnaev, he has been taken alive. The suspect was found in a boat in Watertown, Massachusetts, at around 7:30 Friday evening. He was taken into custody about 8:45 p.m. to applause by police officers and bystanders at the scene. According to reports, Tsarnaev is being transported to Mount Auburn Hospital. "We got him," Boston Mayor Tom Menino announced. Police detailed the capture at a press conference soon after, saying they identified Tsarnaev with a sensor from a helicopter overhead.
