 Boston Police Commissioner Ed Davis says the suspect, Dzhokhar Tsarnaev (JOH'-kahr tsahr-NY'-ev), was hospitalized late Friday in serious condition. Dzhokhar A. Tsarnaev of Cambridge was pulled from his hiding place in a boat parked behind a house on Franklin Street shortly before 8:45 p.m. in this community just outside Boston. A resident of Watertown came out of his house and noticed blood on his boat and that the tarp covering it was ripped. Authorities, using a bullhorn, had called on the suspect to surrender: "Come out with your hands up." Authorities had cast a wide net for the suspect, virtually shutting down Boston and its surroundings after a violent night in which authorities say the brothers allegedly hurled explosives at pursuers, after killing Massachusetts Institute of Technology police Officer Sean Collier and hijacking a car.

 People watch as police search for suspect in the Boston Marathon bombings, Friday, April 19, 2013, in Watertown, Mass. He then took a year off to train as a boxer. New Bedford Police Lieutenant Robert Richard said his department assisted federal investigators in executing a search warrant at a home on Carriage Drive, about 10 minutes from the University of Massachusetts at Dartmouth, where Tsarnaev was a student.
– The manhunt is over. Police caught Boston bombing suspect Dzhokhar Tsarnaev tonight after finding him hiding in a boat in a Watertown backyard, reports WCVB. Tsarnaev was taken by ambulance to a hospital; the AP reports that he is in serious condition. Multiple gunshots were heard at the scene of his arrest earlier this evening, preceding a standoff of about two hours. The developments began shortly after police wrapped up a late-afternoon news conference to say the 19-year-old was still at large. NBC News spoke with a relative of the resident who found Tsarnaev, and the story is a wild one: In the relative's telling, the man was having a cigarette outside when he saw that the boat's tarp was loose; he went to fix it, saw a person and bloody clothes inside the boat, "freaked out," and called police. Helicopters used thermal imaging to confirm Tsarnaev's presence. Some other developments and revelations: “All in all, this has been a tough week, but we have seen the character of our country once more,” said President Obama after the arrest. "Tonight our nation is in debt to the people of Boston and the people of Massachusetts." Politico has more details on his comments. The FBI took two men and a woman in for questioning from a house in New Bedford, but it's not clear how serious it is. A police lieutenant says Tsarnaev may have lived in the off-campus home at some point, reports AP. Authorities lifted the "shelter in place" advisory for residents of Boston, with public transportation now open again. Dzhokhar ran over his wounded brother Tamerlan in his haste to escape last night's shootout with police, reports the Globe. Tamerlan was killed, as was one officer; another officer was wounded. One notable revision: Authorities say neither of the brothers robbed a 7-11 store in Cambridge as police previously reported. A 7-11 did get robbed, but not by them, a store exec tells USA Today. "The police or someone made a mistake. Someone was confused." Tamerlan died wearing explosives and a triggering device, CNN reports. One local auto shop owner tells the Wall Street Journal that Dzhokhar, a regular customer, came to him on Tuesday and said he needed his car "right now." The mechanic protested that the bumper and tail lights weren't on it, but Dzhokhar took it anyway. "I think he probably knew something was going to happen."
