Alben said the brothers exchanged over 200 rounds with the police during the shootout, and left seven explosive devices at the scene. The gunfight lit up the nighttime sky with sights and sounds of a war zone.
“We believe this is to be a terrorist,” said Boston Police CommissionerDavis. “We believe this to be a man here to kill people.”
Officials said Dzhokhar Tsarnaev is a student at the University of Massachusetts in Darmouth 40 miles south of Boston. He is a native of the Chechen region of Russia and became a naturalized U.S. citizen in September of last year.
He and his older brother moved to the United States a decade ago with their parents.
The fast-action that led to Dzhokhar Tsarnaev’s capture started at 10 p.m. in Cambridge, across the Charles River from Boston. Police responding to a 7-11 convenience store robbery near the MIT campus in Kendall Square discovered a campus police officer shot to death in his cruiser. A short time later, a Mercedes SUV carjacking nearby resulted in police pursuit and the shoot-out with the brother suspects in Watertown.
Officials said the suspects threw grenade-like bombs and fired guns at police during and after the chase. A transit policeman helping with the pursuit was seriously wounded.
Officers shot Tamerlan Tsarnaev, the older of the two brothers, when he rushed toward them firing a gun. He was later found to have a small bomb strapped to his body. Emergency room doctors said he died from bullet and shrapnel wounds.
Dzhokhar Tsarnaev, described by the FBI as the “white cap” suspect in FBI video and photo images, fled the shootout by speeding the carjacked SUV through police. Officials said he later fled on foot.
The driver of the stolen SUV told police he was held hostage by the suspects for a half-hour. He said they told him they were the marathon bombers and that they had killed a police officer that very night. He was let go unharmed at a gas station after they had withdrawn $800 from an ATM with his bank card.
