Boston Marathon bombing suspect Dzhokhar Tsarnaev is in serious condition and under heavy guard in a Boston hospital.
Police captured him Friday night hiding in a boat in a backyard in the Boston suburb of Watertown after a 24-hour long manhunt.
Investigators say Tsarnaev, who was believed to be bleeding heavily when he was captured, has been in no condition to answer questions about why he and his dead older brother Tamerlan allegedly set off two bombs at the marathon last Monday, killing three and injuring 176.
This combination of undated photos shows Tamerlan Tsarnaev, 26, left, and Dzhokhar Tsarnaev, 19.
Federal prosecutors are still deciding the exact charges to bring against Tsarnaev. The federal public defender's office says it will represent him in court.
With one suspect dead and the other in federal custody, people in Boston relaxed for the first time in nearly a week Saturday.
The emotions were especially on display at sold-out Fenway Park, where baseball's home town Red Sox honored police, emergency workers, and survivors of the bombings.
U.S. President Barack Obama said the two brothers failed because he said Amercians refuse to be terrorized.

Police and the FBI identified the Tsarnaev brothers late Thursday hours after it released pictures of the two, hoping someone would recognize them. The FBI also says it has video of Dzhokhar placing a backpack along a curb moments before the bombing.
After their pictures were made public, the two allegedly killed a security officer from the Massachusetts Institute of Technology, stole a car, and threw grenades and other explosives at officers during a police chase. Tamerlan was killed in a shootout. Dzhokhar escaped and was found hiding in the boat by its owner, who called police.
The Tsarnaev brothers are ethnic Chechens who came to the Boston area as boys. Family members and friends say they cannot believe the two could have carried out such a dreadful crime. But an uncle who lives in suburban Washington called them losers who brought shame on all Chechens.
