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 was in custody. His brother, 26-year-old Tamerlan, was killed Friday in a furious attempt to escape police.
The suspects were identified to The Associated Press as coming from the Russian region near Chechnya, which has been plagued by an Islamic insurgency stemming from separatist wars.
The two men are suspected of killing a Massachusetts Institute of Technology police officer on campus in Cambridge late Thursday, then stealing a car at gunpoint and later releasing its driver unharmed.
The suspects' clashes with police began only a few hours after the FBI released photos and videos of the two young men, who were seen carrying backpacks as they mingled among revelers at Monday's Boston Marathon. The bombings on Monday killed three people and wounded more than 180 others, and authorities revealed the images to enlist the public's help finding the suspects.
The FBI is asking people and families affected by the Boston Marathon bombings to contact the bureau's Victim Assistance Call Center.
The FBI's Office for Victim Assistance provides emergency assistance, compensation and counseling to victims of domestic and international terrorism.
The call center phone number is 1-800-331-0075. Callers will be put in contact with the victim assistance office.
The FBI is legally mandated to identify victims of federal crimes that it investigates.
