Boston bombings: 'CAPTURED!!! The hunt is over,' police say

[Updated 10:47 p.m. ET] Boston Marathon bombings suspect Dzhokar Tsarnaev is at Boston's Beth Israel Deaconess Medical Center, hospital spokeswoman Kelly Lawman said.

Meanwhile, Senators John McCain and Lindsey Graham congratulated law enforcement on the arrest of the Boston Marathon bombing suspect and noted that the incident should be prosecuted as a terror case. The "perpetrators of these acts were not common criminals attempting to profit from a criminal enterprise, but terrorist trying to injure, maim, and kill innocent Americans," the senators said.

"Under the Law of War we can hold this suspect as a potential enemy combatant not entitled to Miranda warnings or the appointment of counsel."

[Updated 10:11 p.m. ET] "We've closed an important chapter in this tragedy," President Barack Obama said at the conclusion of the Boston Marathon bombing manhunt on Friday night.

[Updated 9:49 p.m. ET] Suspect Dzhokar Tsarnaev is in serious condition in the hospital, Boston police Commissioner Ed Davis said.

But how did law enforcement find suspect Tsarnaev? A Watertown resident saw blood on a boat in his neighbor's backyard, Davis said.

"He opened the tarp and saw a man covered in blood," he said. The man retreated and alerted law enforcement.

Despite being bloody, the suspect exchanged gunfire with authorities from his hiding place, Davis said. Tsarnaev did not have explosives on him at the time of capture, according to Davis.

[Updated 9:41 p.m. ET] Massachusetts is celebrating the collaborative efforts of law enforcement, the public and the media in leading to the capture of the suspect in the Boston Marathon bombings.

"We're so grateful to bring justice and closure to this case," Massachusetts State Police spokesman Col. Timothy Alben said at a news conference in Watertown less than an hour after the capture of suspect Dzhokar Tsarnaev. "We're exhausted, folks, but we have a victory here tonight."

Gov. Patrick Deval praised local, state and federal agencies "who brought their A-game" along with members of the public "for their patience and participation in the case."

"Its a night where I think we're all going to rest easy," he said.

Authorities believe that 19-year-old Dzhokar Tsarnaev is likely still in Massachusetts, state police spokesman Col. Timothy Alben said Friday.

"He's a very violent and dangerous person," Alben said in a news conference Friday. "We do not have an apprehension of our suspect this afternoon, but we will have one."

Massachusetts state troopers will remain in Watertown, where the suspects engaged in an overnight gunfight with police, for at least three more days, Alben said.

Some 200 rounds" of gunfire were exchanged during the firefight, Gov. Deval Patrick added.

One of those patients is in critical condition, 10 are in serious condition, and four are in fair condition. The Boston hospital - one of several in the area treating the wounded - received 23 patients tied to Monday's blasts overall.

Connecticut police have issued a few vehicle alerts today, saying they've been monitoring information coming from investigators across the state line.

[Updated 4:05 p.m. ET] Anzor Tsarnaev, father of the suspects, told Dagestani TV netowrk Zvezda that he believes "someone framed" his sons.

"Someone framed them," Anzor Tsarnaev said during the interview Friday in Russia's North Caucasus republic of Dagestan. "I don't know exactly who did it. But someone did. And being cowards, they shot the boy (Tamerlan) dead. There are cops like this."

Anzor Tsarnaev said that whoever was behind the Boston Marathon bombings "is a bastard."

He said he was trying to get in touch with his family members in Canada and the United States, but he can't get through by phone.

"Those are my kids, you understand? Maybe he will be shot dead, too," he told Zvezda. "They will say, well, he had weapons. Kids with weapons? ... They should arrest him maybe and bring him, but alive. Alive. And justice should decide who's right and who's guilty."

Noting that he had lived in the United States, Zvezda asked him whether he ever had problems with the U.S. justice system.

'No, never. But I just didn't face it ever. So can I know about the justice there? I didn't have any problems," he said.

His older brother Tamerlan Tsarnaev, who was killed in a shootout with police overnight, came to the United States four years after his brother, on Sept. 6, 2006, at the age of 20, the source said. He came legally but was not naturalized. He was a green card holder and in the country lawfully.

[Updated 1:23 p.m. ET] Dzhokar Tsarnaev became a U.S. citizen on September 11, 2012, a federal official said Friday. See profile of the Tsarnaev brothers.

[Updated 1:17 p.m. ET] Here's the latest chronology that CNN has on Thursday night's shooting and subsequent manhunt:

The violence began late Thursday with the robbery of a convenience store, according to Timothy Alben, superintendent of the Massachusetts state police. Soon after, in Cambridge, across the Charles River from Boston, Massachusetts Institute of Technology police officer Sean Collier was fatally shot while he sat in his car, the Suffolk County District Attorney's Office said in a statement.

Police believe the Boston Marathon bombing suspects were responsible for the shooting.

The two suspects, according to authorities, then hijacked a vehicle at gunpoint in Cambridge, telling the driver that they are the marathon bombers, a law enforcement source told CNN's Joe Johns. At some point, apparently at a gas station, the source said, the driver escaped.

Police, who were tracking the vehicle using its built-in GPS system, picked up the chase in Watertown. The pursuit went into a residential neighborhood, with the suspects throwing explosives at the police. A firefight erupted and ultimately one suspect - later identified as Tamerlan Tsarnaev - got out of the car. Police shot him, and his brother ran over him as he drove away, according to the source.

Earlier, there had been reports that Dzhokar Tsarnaev escaped on foot instead of by vehicle.

A source briefed on the investigation said Tamerlan Tsarnaev was wearing explosives and an explosive trigger. He died later at Beth Israel Hospital.

Richard H. Donohue Jr., 33, a three-year veteran of the transit system police force, was shot and wounded in the incident and taken to a hospital, a transit police spokesman said Friday. The officer's condition was not immediately known.

[Updated 12:45 p.m. ET] Police are continuing to run down new leads and go door to door in Watertown in the Boston Marathon terror attack investigation, said Timothy Alben, superintendent of the Massachusetts state police. He told reporters that law enforcement will conduct a controlled blast later in Cambridge, an indication that police found suspected explosives.

[Updated 12:44 p.m. ET] Massachusetts Gov. Deval Patrick says his request for people in the Boston area to stay indoors remains in effect for now. "We know what an inconvenience it is, in Watertown and Cambridge in particular ... but it’s been enormously helpful … to law enforcement.”

[Updated 12:30 p.m. ET] The Kyrgyz government said Friday that the two Boston Marathon suspects moved from Kyrgyzstan 12 years ago to the Russian region of Dagestan, from where the Tsarnaev family emigrated to the United States.

"Given that the suspects left the Republic at the ages of 8 and 15, the State Committee for National Security of Kyrgyzstan considers it inappropriate to link them to Kyrgyzstan," it said.

[Updated 12:25 p.m. ET] Dzhokar Tsarnaev, 19, was registered at the University of Massachusetts-Dartmouth, which ordered its campus evacuated on Friday. The school is located 65 miles south of Cambridge, just west of New Bedford.

"UMass Dartmouth has learned that a person being sought in connection with the Boston Marathon bombing has been identified as a student registered at UMass Dartmouth," the school said in a news release. "The campus is closed. Individuals on campus should shelter in place unless instructed otherwise."

[Updated 12:06 p.m. ET] Boston bombing suspect Dzhokar Tsarnaev has tweeted since the Boston Marathon bombings on what friends of his tell CNN is his Twitter account.

The tweets included one at 1:43 a.m. Wednesday that said, "I'm a stress free kind of guy."

On Monday at 8:04 p.m. - hours after the bombings - he tweeted a lyric from a song that rapper Jay-Z has sampled: "Ain't no love in the heart of the city, stay safe people."

On Tuesday shortly after midnight he tweeted, "There are people that know the truth but stay silent & there are people that speak the truth but we don't hear them cuz they're the minority."

[Updated 11:55 a.m. ET] The uncle of the Tsarnaev brothers told reporters outside his home in Montgomery County, Maryland, this morning that his family is "ashamed" to be related to the suspects.

Ruslan Tsarni said the 19-year-old suspect still on the run "has put a shame on our family, a shame on the entire ethnicity." Tsarni urged his nephew to turn himself in.

He said anyone capable of committing such a crime are "losers."

[Updated 11:20 a.m. ET] U.S. Secretary of State John Kerry praised law enforcement in their hunt for the Boston Marathon attack suspects.

"I think it is fair to say this entire week we have been in pretty direct confrontation with evil," he said. "In the past few days we have seen the best and we have seen the worst of human behavior and it is the best that all of us really want to focus on."

[Updated 10:55 a.m. ET] Taxi service in Boston has been restored, police said. The service had been suspended earlier today because of the manhunt in the Boston bombings case.

[Updated 10:41 a.m. ET] Connecticut State Police say that a vehicle that might be connected to a suspect in the Boston Marathon attack has been recovered in the Boston area. The vehicle is a gray Honda CR-V with Massachusetts plate 316 ES9.

Connecticut police earlier had issued a lookout notice for the vehicle.

This is what Boston police had to say about the vehicle earlier, on Twitter: "Police seeking MA Plate: 316-ES9, ’99 Honda CRV, Color – Gray. Possible suspect car. Do not approach."

[Updated 10:29 a.m. ET] A high school friend of Dzhokar Tsarnaev, the suspect who Boston police say still is at large, is recalling what he remembers about him.

Eric Mercado told CNN that he went to Cambridge Rindge & Latin, a public high school, with Dzhokar Tsarnaev, 19. Both graduated, he said.

"We hung out; we partied; we were good high school friends," Machado told CNN. "We're all, like, in shock. We don't really understand. There were no telltale signs of any kind of malicious behavior from Dzhokar. It's all coming as a shock, really."

[Updated 10:24 a.m. ET] More background on the brothers that several sources tell CNN are the suspects involved in Thursday night's shootings and police chase and Monday's Boston Marathon bombings:

The Tsarnaev brothers were Kyrgyz passport holders, and used those passports when applying for green cards in the United States, an official in the central Asian republic of Kyrgyzstan said, according to CNN's Ivan Watson.

This doesn't mean they were born in Kyrgyzstan or that their family were Kyrgyz natives. Many Caucasus refugees received passports or refugee status in surrounding countries.

[Updated 10:14 a.m. ET] Some background on the brothers that several sources tell CNN are the suspects involved in Thursday night's shootings and police chase and Monday's Boston Marathon bombings:

Dzhokar Tsarnaev, 19, the Boston Marathon attack suspect now at large, came to the United States as a tourist in the early 2000s and asked for asylum while he was here, a federal source said. He was naturalized last year. Tamerlan, the 26-year-old brother who was killed overnight, came "a few years later" and was a green-card holder, not a naturalized citizen, the source said, according to CNN's Mike Ahlers.

[Updated 10:02 a.m. ET] We now have the name of he Massachusetts Institute of Technology police officer who was killed Thursday night - he was Sean Collier, 26, of Somerville, Massachusetts, according to the Middlesex district attorney’s office.

[Updated 9:48 a.m. ET] An aquatic director at Harvard University told CNN that he hired Dzhokar Tsarnaev as a lifeguard more than two years ago, but hasn't seen him for more than a year.

"He seemed like a very quiet, unassuming young man," the aquatic director, George McMasters, told CNN Friday morning. "He showed up on time, watched the water, rotated from position to position fine, got along well with students and swimmers there at the pool."

[Updated 9:34 a.m. ET] Boston police have released a new photo of Dzhokar Tsarnaev - the suspect still being sought in the Watertown area.

[Updated 9:31 a.m. ET] The Boston bombings suspect who was killed in a confrontation with police overnight in the Boston area was wearing explosives and an explosive trigger when his body was recovered, a source briefed on the investigation says, according to CNN's Deborah Feyerick.

Several sources tell CNN that the dead suspect has been identified as Tamerlan Tsarnaev, 26, and the one still being sought in Watertown is Dzhokar Tsarnaev, 19.

Police have publicly said that the dead suspect is the man that the FBI previously identified as "Suspect No. 1" in the Boston Marathon bombings. They also have said publicly that the suspect that they chased and last saw in Watertown overnight is the man that the FBI said was "Suspect No. 2"; Boston police also have said that they're looking for Dzhokar Tsarnaev.

[Updated 9:16 a.m. ET] The brothers suspected in the Boston Marathon attack haven't been connected to the Russian region of Chechnya for many years, the Chechen president's office said, according to the Interfax news agency.

The Tsarnaev family years ago moved out of Chechnya to another Russian region, lived some time in Kazakhstan, and then went to the United States where the family members received a residence permit, the office said.

"Therefore, the individuals concerned did not live as adults in Chechnya," said Alvi Kamirov, press secretary for Chechnya's president.

[Updated 9:01 a.m. ET] Boston police have now named a suspect that authorities have been seeking this morning. "Suspect identified as 19 year-old Dzhokar Tsarnaev of Cambridge. Suspect considered armed & dangerous," Boston police said on Twitter.

Dzhokar Tsarnaev is a Boston Marathon bombings suspect that police are looking for in Watertown following a chase overnight and shootings overnight, several sources told CNN earlier Friday.

Tamerlan Tsarnaev, 26, was the suspect who was killed during a police confrontation overnight, those same sources told CNN.

Police have said that the man identified by the FBI as "Suspect No. 1" in the Boston Marathon bombings was killed in the police confrontation. The man identified by the FBI as "Suspect No. 2" is on the loose, last seen in Watertown, police said.

[Updated 8:52 a.m. ET] A recap of the developments that began Thursday night:

The violence began late Thursday with the robbery of a convenience store, not long after the FBI released images of two suspects in the Boston Marathon bombings, Massachusetts State Police spokesman Col. Timothy Alben said.

Soon after, in Cambridge, across the Charles River from Boston, a Massachusetts Institute of Technology police officer was fatally shot while he sat in his car, the Suffolk County District Attorney's Office said in statement. Police believe the bombing suspects were responsible for the shooting.

The same two suspects, according to authorities, then hijacked a car at gunpoint in Cambridge. They released the driver a half-hour later at a gas station. As police picked up the chase, the car's occupants threw explosives out the windows and shot at officers, according to the district attorney's office.

Officers fired back, wounding one of the men, possibly the person identified by the FBI as "Suspect No. 1." The man died at Beth Israel Hospital. He had bullet wounds and injuries from an explosion, according to officials. The second man apparently escaped.

Richard H. Donohue Jr., 33, a three-year veteran of the transit system police force, was shot and wounded in the incident and taken to a hospital, a transit police spokesman said Friday. The officer's condition was not immediately known.

[Correction at 1:36 p.m. ET] The 8:52 a.m. entry above initially said that the second man apparently escaped on foot. "On foot" has been removed, as that part no longer appears to be the case.

The older of the two brothers had the first name Tamerlan, had studied at Bunker Hill Community College, and wanted to become a engineer, the source said. He then took a year off to train as a boxer, according to the source.

The source said that a posting on a social media site in his name included the comments: "I don't have a single American friend. I don't understand them."

The source added that it should not be assumed that either brother was radicalized because of their Chechen origins.

[Updated 8:07 a.m. ET] "All of Boston" should shelter in place, Massachusetts Gov. Deval Patrick has just told reporters. The same applies to suburbs of Watertown, Newton, Belmont, Cambridge and Waltham, he said.

[Updated 2:40 a.m. ET]: Massachusetts State Police spokesperson Dave Procopio said that they believe multiple possible explosive devices were used against police tonight during this incident at Watertown. It was unclear if the incident, which followed a police chase of a stolen vehicle, was related to the shooting on the MIT campus or any other incident in the Boston area.

[Updated 2:31 a.m. ET]: FBI spokesman Martin Feely tells CNN's Susan Candiotti: "We are engaged with our partners trying to determine if there is a connection." CNN's Drew Griffin, who is on the scene in Watertown, Massachusetts, said FBI agents are on the scene.

[Updated 1:49 a.m. ET]: At least one person was arrested in Watertown, Massachusetts early Friday morning, stripped naked before being taken in custody, CNN photojournalist Gabe Ramirez observed. It is unclear if this arrest was related to the shooting at Massachusetts Institute of Technology campus or any other incident in Boston the area.

[Updated 1:23 a.m. ET]:  Dozens of police have rushed to an area of Watertown, Massachusetts, just over two miles from Cambridge, said CNN's Drew Griffin, who is near the scene. A "very large event has taken place," Griffin said. There were reports that explosives were involved.

[Posted at 12:45 a.m. ET]: A university police officer has died after being shot on the Massachusetts Institute of Technology campus in Cambridge late Thursday, state police spokesman Lt. Mark Riley said. The MIT officer was responding to a disturbance when he was shot, according to the state district attorney's office. He sustained "multiple gunshot wounds."

State police and the FBI were called in after the shooting and found the campus policeman near Building 32 on MIT's campus. He was taken to Massachusetts General Hospital, where he was pronounced dead, the district attorney's office said. Dozens of officers surrounded and cordoned off the building, known as the Stata Center, which houses computer science laboratories as well as the department of linguistics and philosophy, according to MIT's website.

    Two disgruntled domestic terrorist bombed the Boston marathon because their NRA membership was revoked. They couldn't find an elementary school to bomb, so they bombed the marathon. The other terrorist on the loose is suspected to be hiding in the home of one of the domestic terrorist group better known as the GOPT/D gun lobbyists!

    I agree-anything to get more gun laws imposed on Americans. And exactly why are citizens locked down? We do have weapons ya know. If people have concealed carry permits-go about your business and be armed. Citizens around her would do a better job of protecting their families than the cops would. What a joke to punish us because of foreign terrorists that the Obummer admin. is allowing to invade America. Sounds like the family doesn't care about becoming citizens-just given permanent residence status?? Time for them to leave as well. If they don't want to become citizens and American-time to throw them out.

      @worktolive,hey bud they've been invading America before you were born.

      Pete, the WMD was NOT a lie. There was a book written by a former Navy Seal I believe, he said they didn't have nuclear weapons, but they had chemical weapons that were so strong, it could infect, and kill anyone in a 2 mile radius. that is a weapon of mass destruction. Let's look at Baghdad. In a 2 square mile radius, there may be up to 183,148 people. ONE chemical weapon that they had, could kill that many people, and thats only in 2 square miles. There were no nuclear weapons, but there were weapons of mass destruction. WMD isn't just nuclear but chemical or anything that can cause widespan death.

      Gun restrictions are needed to protect Americans from themselves. There are too many mentally unstable people – those who don't have access to healthcare, since the society isn't behaving responsibly in providing those mechanisms; and those who simply forget to take their daily dose of some scary antidepressants.
      Plus, there are too many people with psychiatric religious disorder who hear voices of their imaginary sky-friends from ancient fairy tales.

      Dzhokar Tsarnaev is a citizen of the United States. There's no mention of his mother, but one assumes that she is one, as well. He's been in Cambridge since he was 8 years old. He grew up here. He went to school here. He is an American.

      If you live in Boston and you'd rather go strutting around with a gun, deluding yourself to believe that you can protect yourself from someone who is willing to murder strangers – to kill his own brother in his own attempt to escape – then you go for it. There's no way that could end badly. Not at all.
