WASHINGTON (AP) _ A U.S. law enforcement official and the uncle of the suspects in the Boston Marathon bombings are confirming that the name of the second suspect is Tamerlan Tsarnaev, the older brother of Dzhokhar A. Tsarnaev, 19. Tamerlan Tsarnaev was killed in a gun battle with police in Massachusetts overnight. Three law enforcement officials, speaking on condition of anonymity due to the sensitivity of the ongoing investigation, confirmed the bomb suspects were brothers. One of the officials and the men's uncle confirmed the identity of Tamerlan Tsarnaev.
The uncle, Ruslan Tsarni of Montgomery Village, Md., told The Associated Press that the men lived together near Boston and have been in the United States for about a decade. They traveled here together from the Russian region near Chechnya.
WATERTOWN, Mass. (AP) Two suspects in the Boston Marathon bombing, identified to The Associated Press as coming from the Russian region near Chechnya, killed an MIT police officer, injured a transit officer in a firefight and threw explosive devices at police during their getaway attempt in a long night of violence that left one of them dead and another still at large Friday, authorities said.
A law enforcement intelligence bulletin obtained by the AP identified the surviving bomb suspect as Dzhokhar A. Tsarnaev, 19, of Cambridge, Mass.
Two law enforcement officials told AP that Tsarnaev and the other suspect who was not immediately identified have been living legally in the U.S. for at least one year. Russia's North Caucasus region has been plagued by an Islamic insurgency stemming from separatist wars in Chechnya.
WATERTOWN, Mass. (AP) _ Police are locking down some neighborhoods in Boston and its western suburbs as they search for the remaining suspect in the marathon bombings.
Authorities urged residents in Watertown, Newton, Waltham, Belmont, Cambridge, Arlington and the Allston-Brighton neighborhoods of Boston to stay indoors. All mass transit was shut down.
At least a quarter of a million people live in those suburbs. Many people in the city of Boston and surrounding areas rely on the Massachusetts Bay Transit Authority to get to work.
The announcement Friday morning comes hours after the killing of one suspect, known as the man in the black hat from marathon surveillance footage. The man in the white hat is on the loose and police are calling him a ``terrorist'' who came here ``to kill.''
WATERTOWN, Mass. (AP) _ Authorities say one of two suspects in the Boston Marathon bombing is dead and a massive manhunt is underway for another.
Residents of the Boston suburb of Watertown have been advised to keep their doors locked and not let anyone in.
The Middlesex district attorney says the two men are suspected of killing an MIT police officer at the college late Thursday, then stealing a car at gunpoint and later releasing its driver unharmed. Hours earlier, police had released photos of the bombing suspects and asked for the public's help finding them.
Authorities say the suspects threw explosives from the car as police followed it into Watertown. The suspects and police exchanged gunfire and one of the suspects was critically injured and later died.
Police say the suspect on loose is a ``terrorist'' who ``came here to kill people.''
CAMBRIDGE, Mass. (AP): 1 Boston suspect died at hospital after shootout with cops; explosives thrown in chase.
WATERTOWN, Mass. (AP) The FBI is investigating whether the shooting of a campus police officer at the Massachusetts Institute of Technology and gunfire and explosions in a nearby town are related to the Boston Marathon bombings.
A Massachusetts State Police spokesman says one person suspected in the gunfire and explosions has been accounted for and one is at large.
The FBI says it is working with local authorities to determine what happened.
The MIT shooting on the Cambridge campus Thursday night was followed by reports of violence in nearby Watertown, about 10 miles west of Boston.
A state police spokesman said early Friday there is a ``strong possibility'' the incidents are related.
Cab driver Imran Sais says he heard ``a loud boom'' while standing on a street corner at a police barricade across from a diner.
WATERTOWN, Mass. (AP) _ Police are converging on a neighborhood outside Boston where there are reports of explosives being detonated, and police are telling reporters to turn off their cell phones. Police and the National Guard are in Watertown, where the media have reported hearing gunfire and explosions. A helicopter has been circling overhead. Earlier in the evening an MIT police officer was shot and killed.
