Description:One suspect in the Boston Marathon bombings is dead. The other -- his brother- - was on the run Friday, pursued by an army of police whose manhunt virtually shut down the city.
Tamerlan Tsarnaev, 26, died after an overnight shootout with police. He's the man described Thursday by the FBI as black-capped Suspect No. 1 in the attacks that killed three. His brother, Dzhokhar Tsarnaev, apparently escaped -- leading police to throw a huge dragnet around the region.(2:48)
