WATERTOWN, Mass. —
President Barack Obama said the nation owes a debt of gratitude to law enforcement officials and the people of Boston for their help in the search. But he said there are many unanswered questions about the Boston bombings, including whether the two men had help from others. He urged people not to rush judgment about their motivations.
The breakthrough came when a man in a Watertown neighborhood saw blood on a boat parked in a yard and pulled back the tarp to see a man covered in blood, authorities said. The resident called 911 and when police arrived, they tried to talk the suspect into getting out of the boat, said Boston Police Commissioner Ed Davis.
"He was not communicative," Davis said.
Instead, he said, there was an exchange of gunfire — the final volley of one of the biggest manhunts in American history.
Watertown residents who had been told in the morning to stay inside behind locked doors poured out of their homes and lined the streets to cheer police vehicles as they rolled away from the scene.
Celebratory bells rang from a church tower. Teenagers waved American flags. Drivers honked. Every time an emergency vehicle went by, people cheered loudly.
"They finally caught the jerk," said nurse Cindy Boyle. "It was scary. It was tense."
Police said three other people were taken into custody for questioning at an off-campus housing complex at the University of the Massachusetts at Dartmouth where the younger man may have lived.
"Tonight, our family applauds the entire law enforcement community for a job well done, and trust that our justice system will now do its job," said the family of 8-year-old Martin Richard, who died in the bombing.
The FBI was swamped with tips — 300,000 per minute — after the release of the surveillance-camera photos, but what role those played in the overnight clash was unclear. State Police spokesman Dave Procopio said police realized they were dealing with the bombing suspects based on what the two men told a carjacking victim during their night of crime.
