Scenes From the Manhunt
It was a dramatic 48 hours as police conducted a manhunt for the two brothers thought to be responsible for the Boston Marathon attack.
A dramatic shoot-out in the Boston suburb of Watertown in the early hours of Friday left one brother, 26-year-old Tamerlan Tsarnaev, dead.
His younger brother, Dzhokhar, escaped wounded but was captured Friday night after a standoff with police in a backyard in Watertown. He was believed to be hiding out in a boat with a tarp over it.
"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.

'White Hat' Suspect: Dzhokhar Tsarnaev

Police have identified Tamerlan Tsarnaev as the dead Boston bombing "Suspect #1". He died in the hospital following a dramatic firefight with police in Watertown, Mass. He is pictured here on the day of the bombings in a baseball hat and sunglasses.
Captured! Dzhokhar Tsarnaev
Dzhokhar was on the run for much of Friday and said to be injured from the earlier standoff. Police cornered him in a Watertown backyard after a tip from a neighbor who went outside to smoke and noticed a tarp on the boat was flapping and saw what looked like a curled-up person and bloody clothes.
The Boat Where Suspect Was Hiding
This was the boat that Dzhokhar was hiding out in at 67 Franklin Street in Watertown when police cornered him.
After that tip from a neighbor, thermal imaging from a helicopter confirmed there was a person in the boat. Police swooped in.
'CAPTURED!!!'
A tweet from the Boston police says it all — "CAPTURED!!!" Twitter played a huge role in this manhunt as police and other officials used Twitter to communicate lockdowns and other developments.
