Police officers aim their weapons in Watertown, Mass., early Friday morning.
3. Here’s what we know so far:
1. One suspect is at large; one suspect is dead.
2. These are the alleged Boston Marathon bombers. Last night, authorities released images of the two suspects in Monday’s bombings, which killed three people and wounded more than 180 others. Boston Police confirmed early Friday morning that the two men were tied to the attacks.
3. The two suspects have been identified as brothers, American citizens whose family emigrated to the United States from Chechnya, Russia: Dzhokhar Tsarnaev (at large) and Tamerlan Tsarnaev (deceased). They had been living in Cambridge, Massachusetts, for several years.
4. Despite initial reports, the suspects did not rob a 7-Eleven Thursday night. This began when the suspects allegedly shot a MIT campus police officer in his car around 10:30 p.m. The 26-year-old officer, who died of his injuries, has been identified as Sean Collier.
5. The suspects carjacked a Mercedes-Benz SUV and drove to Watertown, Massachusetts, after they shot the MIT campus police officer. The suspects bragged to the car’s driver that they were the marathon bombers. The brothers began the night driving a Honda Civic, which they used to hijack the SUV.
6. When Watertown police spotted the car and tried to pull it over, the suspects fled, throwing explosives out the window at officers. They exchanged gunfire with police during the chase that followed, and a Boston transit police officer was shot and wounded. Witnesses in Watertown reported hearing multiple gunshots and explosions early Friday morning.
7. Tamerlan Tsarnaev was fatally shot when he ran toward Watertown police officers and attempted to set off an IED that was strapped to his chest. He died soon after he arrived at Beth Israel-Deaconess Medical Center.
8. Dzhokhar Tsarnaev escaped police capture by driving the SUV through a line of police officers. NBC News reports that he drove over his brother as he fled the scene.
9. The city of Boston was on total lockdown from early Friday morning until 6:10 p.m.. Businesses and schools closed for the day. Officials suspended all mass transit. Boston residents were told to stay in their homes until the suspect was caught. The city’s streets were deserted.
4. Here’s how it happened:
Boston police battled the two suspects in the Boston Marathon bombings as a manhunt turned into a chaotic and deadly shoot-out Friday morning in nearby Watertown, Massachusetts, according to state and local officials and social media reports.
“We believe this to be a terrorist. We believe this to be a man who has come here to kill people,” Boston police commissioner Ed Davis told reporters at a press conference held after 4 a.m. Friday in a mall parking lot. Friday morning, the Associated Press and NBC reported that the two men were brothers and legal residents from the Russian region of Chechya and that one, Dzhokhar Tsarnaev, 19, was still at large.
The overnight battle, which began at the Massachusetts Institute of Technology, came just five hours after police and federal authorities released images of two men, wearing baseball caps, in the minutes before and after the bombing, prompting a vast national hunt.
Mass. State Police Superintendent Colonel Timothy P. Alben told reporters last night’s incident began with a robbery at a 7-Eleven convenience store [NOTE: This was later proven not to be true].
An MIT campus police officer died after being shot multiple times Friday evening, according to a statement from the City of Cambridge.
After the shoot-out at MIT, the two suspects then carjacked a Mercedes SUV, Alben said at the press conference. They held the driver, then released the driver, “shaken up but physically unharmed,” the local television station WCVB reported.
The suspects told the carjacking victim that they were the marathon bombers, NBC News reported.
“Several explosive devices were discharged from the car at the police officers,” Alben said.
“One of the suspects was struck and ultimately taken into custody,” he said. “The second suspect was able to flee from that car.”
A witness in Watertown, Andrew Kitzenberg, told The New York Times that he saw two men in jackets exchanging “constant gunfire” with police officers. A police SUV “drove towards the shooters” and was shot until it was badly damaged and rolled out of control, hitting two cars in his driveway, Kitzenberg said.
The two shooters then threw a large bomb that looked “like a pressure cooker,” which then exploded, he said.
One suspect was tackled by police, Kitzenberg told the Times. The other got back into the SUV and drove directly at officers. The car “went right through the cops, broke right through and continued west,” he said.
NBC News reported that the suspect in the car “drove over” the other suspect as he made his escape.
Police named the suspects in the bombing and the frantic Watertown chase as Dzhokhar Tsarnaev, 19, and his older brother Tamerlan Tsarnaev, according to the Associated Press and NBC News.
An official said that “tactical teams” from at least four agencies were pursuing the second suspect, a “light-skinned or caucasian male with longer brown curly hair,” who matched the description of a man at the bombing scene in a white hat, on foot in Watertown Friday morning.
“He should be considered armed and dangerous and is a threat to anybody who might approach him,” Boston police commissioner Ed Davis told reporters.
Speculation on Reddit and Twitter suggested that a suspect could be an American college student who had been reported missing, but NBC reporter Pete Williams, a consistently reliable source through the week in Boston, reported early Monday morning that the suspects had “overseas military training.”
“Law enforcement sources said the suspects have international links and have been in the country legally for about a year,” NBC reported.
The suspect was brought to Beth Israel Deaconess Hospital Medical Center, where hospital CEO Kevin Tabb official described the slain suspect at a press conference as an “adult male” who was brought in by the “large police presence.”
The doctor who treated the suspect, Dr. David Schoenfeld, would not say what was done for the patient once he arrived at the hospital. A second doctor, Richard Wolfe, described the man as suffering from “blast and potentially gunshot wounds … probably a blast injury [and] possibly shrapnel” throughout his trunk.
“We don’t have any identity on the name of the deceased patient,” Tabb said.
Chaos in Watertown
Officers went house to house and yard to yard in Watertown Friday morning, and WCVB reported just before 6:00 a.m. that officers with guns drawn surrounded and entered a house on Dexter Avenue in Watertown, before moving on.
Another man was detained, stripped naked, and searched by the FBI, the journalist Seth Mnookin reported on Twitter. That suspect “end[ed] up being released. Apparently wrong place/time.”
MIT issued a statement early Friday mourning the death of the university police officer: “MIT is heartbroken by the news that an MIT Police officer was shot and killed in the line of duty on Thursday night on campus. Our thoughts are now with the family.”
Watertown is a town just to the west of Cambridge, across the Charles River from Boston.
Watertown Police Chief Edward Deveau and other officials at a news conference just before 6 a.m. said the businesses were asked to stay closed in Watertown and that people need to stay inside in Watertown, Cambridge, Newton, and Waltham. All Metropolitan Boston Transit Authority service also is suspended until further notice, an official said.
Harvard University, in nearby Cambridge, also canceled classes Friday.

Any attempt to draw a connection between Chechnya and Tsarnaevs — if they are guilty — is futile. They were raised in the United States, and their attitudes and beliefs were formed there.

“The special services framed my children because they are believing Muslims,” he was quoted as saying. “Why did they kill Tamerlan? They should have taken him alive. The younger one is now on the run; he was studying in his second year at a medical institute in the US. We were expecting him home in the holidays. Now I don’t know what will happen.”

He followed up on that Thursday while opening the Ice Hockey Under 18 World Championship in Sochi, Russia’s Black Sea resort that will host the 2014 Winter Olympics.
Speaking before the game of Russian and U.S. teams, Putin called for a moment of silence and offered condolences. He said that the fact that the Boston attack occurred during a major sports event made it “particularly disgusting.”

Alina Tsarnaeva told reporters that she had not seen either of her brothers in years and referred to Dzhokhar Tsarnaev — who is still at large — an “amazing child.”
“No I’m not OK — no one is okay right now,” she said. “I’m hurt for everyone who has been hurt. I’m sorry for all the people who are hurt and for all the people who lost their lives.”
