Boston Update: Surving Suspect Now In Custody

The surviving suspect in the Boston Marathon bombings is now in custody with at least one bullet wound. Police cornered a man believed to be the suspect in the Boston Marathon bombings on a boat in a yard in a suburb of the Massachusetts capital, law enforcement officials told CNN.

Reporters had heard two dozen gunshots fired. A number of small explosions, believed to be stun grenades, also were heard.

Authorities say Dzhokar Tsarnaev, 19, escaped an overnight shootout Thursday with police in Watertown, MA which left his older brother 26-year-old Tamerlan Tsarnaev dead.
