BOSTON — The two men wanted in connection with the Boston Marathon bombings engaged in an explosive shootout with police overnight Thursday and into Friday in Watertown, Mass.
Tamerlan Tsarnaev, a 26-year-old who had been known to the FBI as Suspect No. 1 and was seen in surveillance footage in a black baseball cap, was killed overnight, officials said. His brother, a 19-year-old college student who was dubbed Suspect No. 2 and was seen wearing a white, backward baseball cap in the images from Monday's deadly bombing at the marathon finish line, escaped.
