The father of a suspected Boston Marathon bomber started to cry when ABC News told him that his son had been captured alive. 
 
 "Thank God," Anzor Tsarnaev said, speaking in Russian, thanking ABC News for relaying word that his son, Dzhokhar Tsarnaev, 19, was in custody and alive. 
 
 Asked what he wanted to tell his son, Anzor Tsarnaev said, "Tell police everything. Everything. Just be honest." 
 
 Tsarnaev spoke to ABC News on more than one occasion today from his home in Makhachkala, the capital of Dagestan, Russia, as Boston police carried out an intense dragnet for his son. 
 
 Dzhokhar Tsarnaev survived a running gun battle with police during the night that left an MIT security officer dead and a Boston police officer badly wounded. His older brother, Tamerlan Tsarnaev, 26, died in the shootout. 
 
 The father said he had spoken to his sons by phone earlier this week. 
 
 "We talked about the bombing. I was worried about them," Anzor Tsarnaev said. 
 
 He said his sons reassured him, saying, "Everything is good, Daddy. Everything is very good."

 The elder Tsarnaev, in a series of conversations with ABC News, insisted his sons were innocent, but said he would appeal to his son to "surrender peacefully." 
 
 "Give up. Give up. You have a bright future ahead of you. Come home to Russia," the dad said. 
 
 The father warned, however, "If they killed him, then all hell would break loose." 
 
 "If they kill my second child, I will know that it is an inside job, a hit job. The police are to blame," the father told ABC News. "Someone, some organization is out to get them." 
 
 Anzor Tsarnaev said that his sons were "set up" and that they are "very nice kids" who have no experience with weapons and explosives. 
 
 The father said his two daughters, ages 22 and 24, live in the U.S. One lives in West New York, N.J. 
 
 Profiles of the brothers give a conflicting picture. 
 
 The older brother, Tamerlan Tsarnaev, was described as an outgoing person who was a champion boxer, a "decent" pianist, drove a Mercedes and liked the movie "Borat." But in captions on an undated boxing photo album operated by photographer Johannes Hirn, Tamerlan Tsarnaev said, "I don't have a single American friend, I don't understand them." 
 
 He also told the photographer he was a "very religious" Muslim boxer who did not smoke or drink. One caption said he usually did not take his shirt off so girls wouldn't get bad ideas. 
 
 "There are no values anymore," he said, and worried that "people can't control themselves." 
 
 Before he was taken into custody, the younger brother, Dzhokhar Tsarnaev, was described as willing to die in a battle with police. But he was better known for taking acting classes, advanced placement courses and being a star athlete with lots of friends in high school. 
 
 He played soccer every Monday with University of Massachusetts-Dartmouth classmates, but he didn't show up for this week's game. He didn't return his teammates' calls. One teammate told ABC News that Dzhokar Tsarnaev was a "quiet guy" who was "a little bit of a druggie." 
 
 "He never seemed out of the ordinary at all," high school classmate Sierra Schwartz told "Good Morning America" today. "This is not someone who seemed troubled in high school or shy. He was just one of us. It's very weird." 
 
 One of the most surprising details about the younger Tsarnaev brother is the revelation that he became a U.S. citizen last year on 9/11, the anniversary of the worst terror attack in U.S. history.

 Steven Owens told ABC News, "I met him when I was in seventh grade and he was just a great kid. He was fun to be around. Very studious, very smart. I don't remember a time when he was ever having trouble in school. He was a great athlete. Great to be around." 
 
 Owens said Tsarnaev "always had a positive attitude," but had expressed some political opinions in school. 
 
 "He always thought the war [Iraq, Afghanistan] was stupid," Owens said. "He didn't enjoy the idea of war. We didn't really talk about it much. The only time it ever really came up was when we were learning about it in school." 
 
 When Owens first saw authorities' photos of Tsarnaev, he wasn't positive it was him since he hadn't seen him in a few years. 
 
 "I started looking through my yearbook because I thought I recognized him and there he was," Owens said. "I was just so surprised." 
 
 After high school, Tsarnaev went to UMass Dartmouth. Today students were evacuated from their dorms, following confirmation that Tsarnaev had lived in the Pinedale residence hall. 
 
 The search for Tsarnaev, of Cambridge, Mass., had effectively shut down Boston and its surrounding cities, including Watertown, Mass.. 
 
 Bomb Suspects Uncle Calls Nephews "Losers" 
 
 Both brothers were born in Kyrgyzstan, according to their uncle, Ruslan Tsarni, who said he has not seen his nephews since December 2005. The uncle was angry over what his nephews are accused of doing. 
 
 The enraged uncle said the only explanation for their behavior is "hatred to those that were able to settle themselves" and "being losers." 
 
 "If you are alive, turn yourself in and ask for forgiveness from the victims, from the injured and from those who left," Tsarni shouted, delivering a message to his nephew. "He put a shame on our family. He put a shame on the entire Chechen enthnicity." 
 
 John Curran, Tamerlan Tsarnaev's former boxing coach, told ABC News that Tsarnaev was the New England champion for two or three years in a row and was considering turning pro. Curran said he had not been in contact with him since 2010. 
 
 Curran said that before the bombing he would have agreed with the portrayal of Tsarnaev as a peaceful, courteous young man. 
 
 "I would agree on all of those if I was asked two days before the bombing what I thought of this young man," Curran said. "I'd say he was a fine young man. Very good athlete. Very courteous. Just a nice guy. I'm shocked beyond belief he was involved in this." 
 
 Curran said Tamerlan Tsarnaev was an extrovert and his brother an introvert. 
 
 Sierra Schwartz said she went to Cambridge Rindge and Latin High School with Dzhokhar Tsarnaev. She recognized him immediately when she saw his photo released by authorities. 
 
 "I was like, 'Wow, that looks just like Dzhokhar,'" she said. She then noticed that his Facebook page had been deleted. 
 
 Schwartz knew he went to college, but did not remember where. She last saw him in Cambridge in the summer of 2011 before starting college. She was not aware that he had a brother. 
 
 "He was a great athlete. He did well. I think he won a scholarship for it," Schwartz said. "This is very unexpected. ... This is out of the ordinary. Completely shocking."

 Schwartz is still reeling from the news that her former classmate had become the most wanted person in America. 
 
 "When I woke up, it's like I'm living a nightmare right now. It can't be described," she said earlier today. 
 
 "We all knew him for four years and that's something a lot of people can't say," she added. 
 
 The Monday bombing near the finish line of the Boston Marathon killed three people and injured more than 170.

 Boston and its suburbs, universities and transit system were on total lockdown Friday as police hunted door to door for marathon bombing suspect Dzhokhar Tsarnaev -- on the loose after his accomplice brother was killed in a stunning chain of events that left one cop dead and another injured, officials said. 
 
 During a desperate effort to flee after their photos were released by the FBI, the brothers carjacked a Mercedes SUV and told the driver they were the men behind Monday's double-blast attack at the race and had just killed a campus security officer, a source told NBC News. The driver was released unhurt. 
 
 The older brother, Tamerlan Tsarnaev, was killed after a wild chase and firefight, but Dzhokhar was still at large in a densely populated area, and an associate was being sought. Adding to the nightmare, an explosive was found in Boston Friday morning and disabled, an official said. 
 
 The suspects' uncle, Ruslan Tsarni, called them "losers" and urged Dzhokhar, a naturalized American citizen of Chechen origin, to turn himself in. 
 
 "We're ashamed," he thundered outside his Maryland home. 
 
 Three dozen FBI agents were surrounding the Cambridge, Mass., home where the brothers grew up after moving to the U.S. a decade ago, seeking asylum. They feared it could be booby-trapped and planned to conduct a controlled explosion before a full search, state police said. 
 
 NBC's Lester Holt reports from Watertown, Mass., where Boston and state police, SWAT teams and a helicopter are engaged in a tense search for a suspect in the Boston Marathon bombing who is still at large. 
 
 Across the area, as police cars screamed down streets and helicopters hovered overhead, authorities urged the public to stay inside and keep their doors locked to anyone but law-enforcement officers. 
 
 "There is a massive manhunt under way," Massachusetts Gov. Deval Patrick said. "We are asking people to shelter in place." 
 
 Subways and buses were shut down, and Amtrak service to Boston was cut. Harvard University, Boston University, the Massachusetts Institute of Technology and Emerson University were closed. The University of Massachusetts' Dartmouth campus was being evacuated because someone wanted in the case is registered at the school. 
 
 The lockdown initially affected more than 300,000 people in Cambridge, Watertown, Newton, Brighton, Allston and Belmont, but by 8 a.m., the entire city of Boston was paralyzed, officials said. 
 
 Watertown, where the second suspect was last seen, was the epicenter of a sprawling search. By 12:30 p.m., police estimated, 60 percent of the homes had been searched. Frightened residents were trapped inside as convoys of heavily armed officers and troops arrived by the hour. 
 
 The overnight violence began at MIT about five hours after the FBI released surveillance photos of two "extremely dangerous" men suspected of planting two bombs near the finish line of Monday's Boston Marathon, killing three and wounding 176.

 Tips about the identity of the suspects were still pouring in when the Tsarnaev brothers fatally shot MIT patrol officer Sean Collier, 26, in his vehicle at 10:20 p.m., law enforcement officials said.

 The brothers then carjacked a Mercedes SUV, holding the driver captive for a half-hour while they tried to use his cash card to get money from three ATM's, a source said. At the first, they put in the wrong number; at the second, they took out $800 and at the third, they were told they had exceeded the withdrawal limit, the source said. 
 
 The man was released unharmed at a gas station in Cambridge, sources said. As they sped toward Watertown, a police chase ensued and the suspects tossed explosive devices out the window, officials said. 
 
 There was a long exchange of gunfire, according to Andrew Kitzenberg of Watertown, who took photos of the clash from his window and spread them on social media. 
 
 “They were also utilizing bombs, which sounded and looked like grenades, while engaging in the gunfight,” he told NBC News in an interview. “They also had what looked like a pressure-cooker bomb. 
 
 “I saw them light this bomb. They threw it towards the officers,” he said. “There was smoke that covered our entire street.” 
 
 A transit officer, identified as Richard H. Donahue, 33, was seriously injured during the pursuit. Authorities said he was in surgery at Mount Auburn Hospital. 
 
 Kitzenberg said he saw the firefight end when Tamerlan Tsarnaev ran toward the officers and ultimately fell to the ground. 
 
 Tamerlan -- the man in the black hat from FBI photos released six hours earlier -- had an improvised explosive device strapped to his chest, law enforcement officials said. 
 
 Dzhokhar -- who was wearing a white hat in the surveillance photos from the marathon -- drove the SUV through a line of police officers at the end of the street, Kitzenberg said. 
 
 Police said Dzhokhar has a Massachusetts driver's license and lives in Cambridge. He was described as light-skinned and with brown, curly hair, and wearing a gray hoodie. The FBI released more photos of him, including a surveillance camera photo from a 7-Eleven. 
 
 His father, in Russia, told the Associated Press he was "a true angel" and described him as a medical student who was expected to visit for the holidays. 
 
 Authorities painted a starkly different picture. 
 
 "We believe this man to be a terrorist," Boston Police Commissioner Ed Davis said. "We believe this to be a man who's come here to kill people." 
 
 Armored humvees and busloads of law-enforcement could be seen rolling into Watertown in the hours after the gunfight. 
 
 "We've got every asset we could possibly muster on the ground right now," Patrick said. 
 
 Later Friday morning, attorney General Eric Holder and FBI Director Robert Mueller headed to the White House to brief President Obama on the developments. 
 
 Secretary of State John Kerry, who is from Massachusetts, praised law enforcement for their work during "a pretty direct confrontation with evil." 
 
 "In the past few days we have seen the best and we've seen the worst of human behavior, and it's the best that all of us really want to focus on," he said. 
 
 Senate Intelligence Committee chairwoman Dianne Feinstein told NBC News it's clear the marathon bombing was "a terrorist attack." 
 
 "It's also clear, you know, that you know you don't have to be a card-carrying member of any terrorist group to commit a terrorist attack," she said.

– The father of suspected Boston Marathon bomber Dzhokhar Tsarnaev didn't have reassuring words when he spoke to ABC News from his Russian home today, warning that "all hell would break loose" if his son died. "If they kill my second child, I will know that it is an inside job, a hit job. The police are to blame," Anzor Tsarnaev said. "Someone, some organization, is out to get them." He says his sons are innocent, but still urged Dzhokar to surrender without a fight: "Give up. Give up. You have a bright future ahead of you. Come home to Russia." Dzhokhar's brother Tamerlan reportedly died in an overnight gunfight with police. In a separate emotional interview with People, a "screaming and yelling" Anzor insisted his sons "hated guns" and "hate terrorists." Anzor said he was worried about his sons when he heard about the bombing Monday, and spoke to them by phone. They told him, "Everything is good, Daddy. Everything is very good." In an earlier interview with the AP, he described Dzhokar as "a true angel." Dzhokhar's uncle is also urging him to turn himself in. Ruslan Tsarni gave a media briefing outside his home in Maryland, where he was asked what he would say to his nephew. "I would say Dzhokar, if you are alive, turn yourself!" he bellowed, "and ask forgiveness from the victims, from the injured, and from those who left! Ask forgiveness from these people! ... He put a shame on our family! He put a shame on the entire Chechnyan ethnicity!" The brothers' aunt, speaking in Toronto, suggested that images of them at the marathon had been doctored in order to frame them, reports Business Insider. "I don't trust the FBI," said Maret Tsarnaeva. "Show me the evidence." (See video of her remarks in the gallery.) Media outlets have been tracking down former friends and acquaintances of the brothers, and one of them echoed the "angel" description to CNN, calling Dzhokhar "a walking angel" who "smokes a little weed," Vanity Fair reports.
