Boston police have confirmed the second suspect in the Boston Marathon bombing is in custody after being apprehended in the back yard of a home in Watertown, Mass.
The Boston Globe reported that Dzhokhar A. Tsarnaev, 19, was taken into custody around 8:45 p.m. Eastern time. He was taken to Beth Israel Deaconess Medical Center in Boston by ambulance.
Police at a press conference Friday night said Tsarnaev was in "serious condition."
CBS News posted a photo of what appears to be the suspect on the ground surrounded by authorities, while The Atlantic featured a grainy video still from The Associated Press of Tsarnaev seen in an ambulance.
The capture signaled the end of an intense manhunt that began Monday after two bombs exploded at the finish of the Boston Marathon, killing three and injuring 170 -- some critically.
"Tonight our nation is in debt to the people of Boston and the people of Massachusetts," President Barack Obama said in a White House news conference Friday night. "Bostoninans responded with resolve and determination (all police) responded with professionalism ... we can close a chapter on this tragedy."
Speaking from the White House briefing room, Obama said, "Whatever hateful agenda drove these young men to such heinous acts will not prevail." He added, "Whatever they thought they could ultimately achieve ultimately failed."
Noting that "in this age of instant reporting, tweets and blogs, there’s a temptation to latch on to many bits of information, sometimes to jump to conclusions," Obama saluted the people of Boston for not responding to the attack by exhibiting prejudice against any group of people.
The nation, he said, must "take care not to rush to judgment -- not about the motivation of these individuals; certainly not about" religious or ethnic groups.
Obama also addressed the fertilizer explosion in West, Texas, and assured the people who suffered through the Wednesday tragedy that they have not been forgotten.
"All in all, it's been a tough week," Obama said.
Before Obama addressed the country, the Boston Police Department held a press conference to address the capture of Tsarnaev.

"We have a victory here tonight. But let's not forget those people we lost," said Col. Timothy Alben of the Massachusetts State Police.
Gov. Deval Patrick called the Marathon bombings a complicated and challenging case, and thanked to all members of the public for reviewing photos.
"Tonight we are all, I think, gonna rest easy," Patrick said.
Thanking the Boston Police Department, Mayor Thomas Menino said, "Thank you, thank, you, thank you ... we'll be able to sleep tonight because of the work of these individuals."
Several televised reports showed crowds Friday night cheering after news spread the suspect was in custody. But in the midst of the celebrations, Boston police also sent out a tweet in honor of the victims of the bombing and overnight events.
