Brothers Dzhokhar Tsarnaev, 19, and Tamerlan Tsarnaev, 26, are believed to be behind Monday's Boston Marathon tragedy and on Thursday, just hours after their images were released to the public, led police on a manhunt from MIT through Watertown, Mass.
During a press conference on Thursday afternoon, the suspects' images were splashed all over the TV and Internet in hopes that the general public could identify and help locate the alleged Boston Bombers.
Boston Marathon Bombing
The brothers are believed to have planted the homemade bombs that exploded during the Boston Marathon on Monday, killing three people and injuring around 170.
Boston Bombing Timeline
The Tsarnaev brothers remained in the Boston area after allegedly setting off the marathon blasts on Monday. By Thursday, after the FBI ID'd them as suspects and released their images to the public, they engaged in a shootout that killed an MIT police officer in Cambridge before leading the police on hot pursuit to nearby Watertown, where guns and grenades blazed overnight in a violent confrontation.
Tamerlan Tsarnaev, 26, was killed in a shootout early Friday morning. He was pronounced dead at 1:35 a.m. at Boston’s Beth Israel Hospital.
Anzor Tsarnaev, the suspects' father, described his 19-year-old son as “an accomplished medical student” and “a true angel" to Russian media. But Chechen leader Ramzan Kadyrov, disowned the brothers. Speaking through his press spokesman, Kadyrov told Russian news agency Interfax that Tsarnaev brothers no longer had any connection with Chechnya.
Police spotted the Tsarnaev brothers on security video inside a 7/11 store in Cambridge, Mass., at approximately 10:20 p.m. and became engaged in a shootout with campus police at Massachusetts Institute of Technology. One MIT police officer was killed in the exchange.
The city remains on lockdown Friday with all mass transit, universities and retail outlets closed. Taxis have been ordered off the streets and Amtrak service between Boston and Providence, R.I., has been suspended. And authorities have ordered more than 300,000 residents of Watertown and neighboring areas to stay inside. Police have warned residents of Watertown to stay inside and not come to the door for anyone save for clearly identifiable law enforcement.
Engaged in a shootout with police, Tamerlan and Dzhokhar Tsarnaev hurled home-made bombs and grenades from the window of the Mercedes SUV they hijacked after killing an MIT campus police officer.
The violent shootout in Watertown, Mass., set off sirens early Friday and launched a bullet into the home of Adam and Megan Marrer. "We found a hole in the living room wall and a bullet on the floor that clearly had been from the crossfire of the firefight, the gunfight, on the street earlier," Megan Marrertold Today later in the morning.
Nineteen-year-old Dzhokhar Tsarnaev survived and escaped the Watertown shootout, allegedly driving over the body of brother Tamerlan as he fled the scene.
The day the FB released his photo in connection with the Boston Marathon bombings, Dzhokhar Tsarnaev was active on social media. On Facebook, he listed his current city as Boston, his world view as Islam and his personal priorities as "career and money."
"He put a shame on our family. He put a shame on the entire Chechen ethnicity," said Ruslan Tsarni of his nephew in a fiery news conference, imploring: "Dzhokar, if you're alive, turn yourself in and ask for forgiveness!"
Massachusetts Governor Deval Patrick
Massachusetts Governor Deval Patrick held a news conference to tell residents of Boston and neighboring communities to stay indoors amid the "massive manhunt."
Five hours after their images were released to the public, Dzhokhar Tsarnaev andTamerlan Tsarnaev allegedlyrobbed a 7/11 near MIT and led police on a chase into Watertown, Mass. One MIT police officer was killed and one MBTA officer was in critical condition and in surgery on Friday morning.
Boston went on lockdown Friday with all mass transit, universities and retail outlets closed and residents ordered to stay inside. Heavily armed SWAT, tactical and bomb squad teams on the ground in Watertown and Cambridge asked media to put their cameras down as they pursued Dzhokhar Tsarnaev.
On the Scene
Police on the scene were reportedly avoiding use of cell phones for fear that they might trigger bombs. Said ABC's Brian Ross, reporting from Boston: "One of our producers was even told, ‘Keep your cell phones off if you want to stay alive.'"
ABC News producer Megan Chuchmach was ordered to drop to the ground when law enforcement spotted her wearing a backpack. “They told me they were suspicious of my backpack,” Chuchmach explained on ABC.
Armed and Ready on the Roof
The FBI manned a rooftop in the manhunt to apprehend surviving suspect Dzhokhar Tsarnaev as well as possible accomplices.
