WASHINGTON -- President Barack Obama says the capture of a suspect in the Boston Marathon bombing closes what he calls "an important chapter in this tragedy."
Obama spoke from the White House briefing room shortly after law enforcement took 19-year-old Dzhokhar Tsarnaev into custody in a boat in a Watertown, Mass., neighborhood. His older brother was killed earlier Friday in an attempt to escape police.
Obama says the nation owes a debt of gratitude to law enforcement officials and the people of Boston for their help in the search for the men.
Obama says there are still many unanswered questions about the Boston bombings, including whether the two men had help from others. He is urging the public to not rush to judgment about their motivations.
