BREAKING NEWS: A bullet-riddled SUV was taken from a home in the Watertown section of Boston, as police tightened the perimeter where the remaining Boston Marathon bomnbing suspect could be hiding.
Earlier, multiple explosions echoed from inside a house, and the situation was fluid following a chaotic night of mayhem that included the murder of a Massachusetts Institute of Technology police officer and a shootout with police, authorities said early Friday.
Police believe the two suspects from Monday's terror attack are brothers, possibly from Chechnya or a nearby region, according to sources who spoke to Fox News. The man on the loose was identified as Dzhokhar A. Tsarnaev, 19, of Cambridge, Mass. They are believed to have been here for 'several years,' sources said.
Schools are closed, train and bus service is suspended and police were telling residents of neighborhoods including Cambridge, Waltham, Watertown, Newton, Arlington and Belmont to stay indoors. Police have formed a wide perimeter and believe the suspect is on foot, armed and dangerous, inside.
"Suspect No. 1 is dead, Suspect Two is on the run," Massachusetts Gov. Deval Patrick said at a Friday morning press conference. "There is a massive manhunt underway."
