Boston marathon blasts : FBI releases pictures of suspects, one killed in gunbattle at MIT
Boston police are on a manhunt to capture the marathon bombing suspect. Officials identified him as Dzhokhar Tsarnaev,19. His brother, 26-year-old Tamerlan Tsarnaev, who is also a suspect, was shot down by the police.
The other suspect, who was killed, was identified as Tamerlan Tsarnaev, 26, officials said. Both suspects are brothers and investigators believe they were Chechens.
The FBI released photos and video of two suspects in the deadly Boston Marathon bombings and asked for the public's help in identifying the men.
FBI Agent Richard DesLauriers said the images are from surveillance cameras near the explosion sites shortly before Monday's blasts at the world's most famous marathon and shows two men with backpacks.
The men are seen walking together in the crowd, and the man in the white cap is seen setting down a backpack at one site near the finish line, the FBI said.
Generally, law enforcement agencies release photos of suspects only as a last resort, when they need the public's help.
The bombs were crudely fashioned from ordinary kitchen pressure cookers packed with explosives, nails and ball bearings, investigators and others close to the case said. Investigators suspect the devices were then hidden in duffel bags and left on the ground.
They looked much like typical university students, but the FBI in the press conference described them as armed and extremely dangerous, and urged anyone who sees or knows them to tell law enforcement agencies.
