The Boston Marathon bombing suspect was captured alive but wounded Friday night after holing up in a boat in a suburban backyard following a bloody rampage that left a cop dead and a daylong manhunt that shut down the city.
The arrest of Dzhokhar Tsarnaev, 19, and the earlier death of his brother during a firefight with cops, ended five days of terror sowed by the double bombing at the marathon finish line, which killed three people, wounded 176 and left the city of Boston on edge.
"We got him," Boston Mayor Tom Menino tweeted. "CAPTURED!!! The hunt is over. The search is done. The terror is over. And justice has won," the Boston Police Department said on its Twitter account.
Cops cheered as the suspect was taken into custody in Watertown, Mass., just before 9 p.m. Later, the people of Watertown flooded the streets, cheering every passing police car and armored vehicle in an impromptu parade. Chants of "USA! USA!" broke out. In Boston, people danced in the streets outside Fenway Park. Police cornered Tsarnaev -- a naturalized U.S. citizen of Chechen origin -- around 7 p.m., less than an hour after police lifted a stay-indoors order for the city and its suburbs.
A resident had gone outside to smoke and noticed a tarp on the boat was flapping, a relative told NBC News. When he went to investigate, he saw what looked like a curled-up person and bloody clothes.
The man "freaked out," ran into the house and called police, the relative said. Thermal imaging from helicopters confirmed there was a person in the boat, officials said.
Over the course of two hours, several bursts of gunfire could be heard. The police exchanged fire with Tsarnaev, threw flash-bang grenades designed to disorient him and brought a negotiator to the scene as night fell, officials said.
Just before 9 p.m., the wounded Tsarnaev was taken into custody. "He sustained significant blood loss," a law enforcement official at the scene said. As an ambulance took the suspect to Boston Beth Israel Deaconess Hospital where he was in serious condition people lining the streets applauded in joy and relief.
We are so grateful to be here right now, so grateful to able to bring justice and closure to this case, Massachusetts State Police Col. Timothy Alben said at a briefing. Were exhausted, folks, but we have a victory here.
President Barack Obama praised the outcomes but said many questions remained. Among them, he said: Why did young men who grew up and studied here as part of our communities and our country resort to such violence?
