URGENT - Boston-Capture-Color
(CNN) -- Law enforcement officials erupted in cheers in Watertown, Masssachusetts, on Friday night -- moments before Boston police tweeted that the lone remaining suspect in the Boston Marathon bombings was in custody. After the ebullient shouts, police began heading away from the backyard of a Watertown home where the suspect, Dzhokar Tsarnaev, was believed to have been holding up in a boat. Soon thereafter, an official in a law enforcement vehicle with tinted windows was asked by someone, "Is that him?" The person inside the vehicle responded, "Yes" -- precipitating more cheers among the residents gathered nearby.
