WATERTOWN, Mass. (AP) — Boston Police say a 19-year-old college student wanted in the Boston Marathon bombings is in custody after a manhunt that left the city virtually paralyzed and his older brother and accomplice dead.

Police announced via Twitter that Dzhokhar Tsarnaev (JOH’-kahr tsahr-NY’-ev) was in custody. His brother, 26-year-old Tamerlan, was killed Friday in a furious attempt to escape police.

The brothers are suspects in Monday’s marathon bombings, which killed three people and wounded more than 180 others. The men are also suspected of killing a Massachusetts Institute of Technology police officer in his vehicle late Thursday.

Authorities in Boston had suspended all mass transit and warned close to 1 million people in the entire city and some of its suburbs to stay indoors as the hunt for the remaining suspect went on.

Crowds gathered after a nearly 28 hour lockdown to applaud and cheer the Boston area authorities.
