WATERTOWN, Mass. - One man suspected in the Boston Marathon bombings is dead and an enormous manhunt is on for a second after a violent night in the suburbs of Watertown and Cambridge, Mass.
All residents of the city of Boston and surrounding suburbs have been ordered to lock themselves inside their homes and only respond if a uniformed officer is at the door.
Around 10:20 p.m. Thursday authorities responded to reports of a robbery at a convenience store and shots fired on the campus of the Massachusetts Institute of Technology in Cambridge, just outside Boston. Responding officers found an MIT campus police officer who was responding to a disturbance is found shot multiple times in his vehicle, apparently in a confrontation with the Boston Marathon bombing suspects. He was later pronounced dead at a hospital.
Shortly afterward, two armed men reportedly carjacked a Mercedes SUV in Cambridge. A man who was in the vehicle is held for about a half hour and then released unharmed at a gas station on Memorial Drive in Cambridge.
Police spotted the vehicle and pursued the carjacked vehicle in Watertown, just west of Cambridge. The suspects threw some kind of explosive devices from the vehicle in an apparent attempt to stop police.
The carjackers and police exchange gunfire in what is described as a rolling shootout. A Boston Transit Police officer was seriously injured. He was described as being in surgery Friday morning. One suspect, tentatively identified as 26-year-old Tamerlan Tzarnaev, was critically injured and later pronounced dead at a hospital. Unconfirmed reports say Tamerlan Tzarnaev was wearing explosives, and may have been run over by his brother as he fled police in the stolen SUV.
The Associated Press reports that the bomb suspects are from a Russian region near Chechnya and lived in the United States for at least 1 year. The man on the loose is identified as Dzhokhar A. Tsarnaev, 19, who has been living in Cambridge, Mass.
Currently the city of Boston and the suburban communities of Watertown, Cambridge, and a handful of others are locked down as authorities engage in a manhunt for the other suspect. Public transportation has been shut down, as have schools and universities in the Boston area.
Around 4:30 a.m., Friday Massachusetts state and Boston police held a short outdoor news briefing telling people living in that section of eastern Watertown to stay in their homes. Hours later, that order was expanded to what amounts to the entire Boston area.
