WATERTOWN, Mass. (AP) — The two suspects in the Boston Marathon bombing killed an MIT police officer and hurled explosives at police in a car chase and gun battle overnight that left one of them dead and his brother on the loose, authorities said Friday as thousands of officers swarmed the streets in a manhunt that all but paralyzed the Boston area.
The suspects were identified by law enforcement officials and a family member as Dzhokhar and Tamerlan Tsarnaev, brothers from a Russian region near Chechnya, which has been plagued by an Islamic insurgency stemming from separatist wars.
Tamerlan Tsarnaev, known to the FBI as Suspect No. 1 and seen in surveillance footage in a black baseball cap, was killed in a gun battle with police in Massachusetts overnight, officials said. His 19-year-old brother — dubbed as Suspect No. 2 and seen wearing a white, backwards baseball cap in the images from Monday's deadly bombing at the marathon finish line — escaped.
The law enforcement officials spoke on condition of anonymity because of the sensitivity of the ongoing investigation.
In Boston, authorities suspended all mass transit and urged close to a million people in all of Boston and some of its suburbs to stay indoors as they searched for the remaining suspect, a man Businesses were asked not to open Friday. People waiting at bus and subway stops were told to go home.
"We believe this man to be a terrorist," said Boston Police Commissioner Ed Davis. "We believe this to be a man who's come here to kill people."
The endgame — at least for Suspect No. 1 — came just hours after the FBI released photos and video of the two young men at the marathon finish line and appealed to the public for help in identifying and capturing them. Tips came pouring in to the FBI immediately but exactly how authorities managed to close in on the two young men was not immediately disclosed.
