BOSTON (CBSNewYork/AP) -- The surviving Boston Marathon bombing suspect was hospitalized under police guard Saturday morning, as the story unfolds for how he and his brother allegedly committed a brutal terrorist attack.
CBS News' Terrell Brown reported Saturday morning that Dzhokhar Tsarnaev, 19, was being treated Saturday morning at Beth Israel Deaconess Medical Center in Boston.
He was in serious, but stable, condition as of Saturday afternoon, Massachusetts Gov. Deval Patrick said.
"He's not yet able to speak, so they'll be some time in the recovery," Patrick told reporters outside Fenway Park Saturday afternoon.
A wound to the back of Tsarnaev's neck appears to be preventing him from communicating, and investigators wonder if it may have been the result of a failed suicide attempt, CBS News reported.
U.S. officials said a special interrogation team for high-value suspects would question him without reading him his Miranda rights, invoking a rare public safety exception triggered by the need to protect police and the public from immediate danger.
The exemption – invoked after the attempted bombing of an airliner on Dec. 25, 2009, along with the attempted Times Square bombing in 2010 – gives officials 48 hours to try to extract information before they are required to read Miranda rights.
Still, the American Civil Liberties Union has taken issue with the choice not to read Tsarnaev his Miranda rights.
Federal public defenders have agreed to represent the suspect in the Boston Marathon bombings.
Miriam Conrad, the federal defender for Massachusetts, says her office expects to represent Dzhokhar Tsarnaev ) after he is charged.
Tsarnaev remained hospitalized Saturday after being wounded in a firefight with police Friday. His brother was killed.
Conrad says she believes Dzhokhar should have a lawyer appointed as soon as possible because there are ``serious issues regarding possible interrogation.''
Meanwhile Saturday, Massachusetts State Police released aerial photos of Dzhokhar Tsarnaev hiding out in a boat in a Watertown, Mass., backyard where he was captured.
Investigators scoured a Cambridge residence, crime scenes in Boston, Cambridge, and Watertown, and dorm room in the Pine Dale residence hall where Tsarnaev lives in their search for evidence.

From there, U.S. Attorney Carmen Ortiz says a lot of work remains.
"This will continue to be an ongoing and active investigation as we sort all of the details, continue to evaluate a tremendous amount of evidence, and file our formal charges," she said Friday night.
Following Dzhokhar Tsarnaev's arrest, the people of Boston poured into the streets, free from fear, CBS 2's Weijia Jiang reported. They had been hiding in their homes as an army of officer took over their town, going block by block and door-to-door looking for a terrorist.
"We will determine what happened, we will investigate any associations these terrorists may have had and we'll continue to do what ever we have to do to keep our people safe," President Barack Obama said after the capture.
CBS News senior correspondent John Miller reported Tsarnaev was found bleeding and hiding in a boat in the backyard of the residence at 67 Franklin St. The homeowner noticed a tear in the boat's tarp and later a lot of blood and called 911, saying there was "a bloody mess" in his boat. Three officers arrived on the scene and investigated the boat, discovering the suspect.
"The man who found him at the boat said he was covered in blood we assume that those injuries occurred the night before, there was an exchange of gunfire at the boat," said Boston Police Commissioner Ed Davis.
Members of law enforcement then pulled back and waited out the suspect for approximately 90 minutes before using flash-bang grenades to startle Tsarnaev before moving in and making the arrest, Miller reported.
Sources told CBS News' Miller that Tsarnaev suffered gunshot wounds to the neck and leg and had lost a lot of blood before being captured.
It took time to end the standoff the way investigators wanted, with a live suspect to interrogate.
"It was a very, very complicated case, a very challenging case, and there are still questions remaining to answer," said Massachusetts Gov. Deval Patrick.
The residence of the takedown is less than a mile from where Tamerlan Tsarnaev, 26, the fugitive's brother and alleged co-conspirator in the marathon bombings, was killed during a shootout with law enforcement on Thursday night, CBS 2's Tony Aiello reported.
The brothers are suspected in the bombings that left three people dead and 176 injured at the finish line of the Boston Marathon this past Monday. But the chain of events dates back 11 years, when Dzhokhar Tsarnaev moved to Cambridge.
Dzhokhar Tsarnaev, an ethnic Chechen, came to the Massachusetts in 2002, became a lawful U.S. resident in 2007, and became a naturalized U.S. citizen on Sept. 11, 2012 – the 11th anniversary of the terrorist attacks that destroyed the Twin Towers of the World Trade Center.
He was a pre-med student at the University of Massachusetts-Dartmouth, with a partial scholarship from the City of Cambridge.
Larry Aaronson, one of Tsarnaev's teachers, was shocked by his alleged involvement in the heinous act of terrorism.
"People have said to me, 'Why didn't you call people and see who could identify this person? (My answer was) because there is no way that it could be this kid. Not Dzkohar! Not him," Aaronson said, "because there is nothing about him that would suggest anything like that –politics, religion, nothing."
Tamerlan Tsarnaev was not the model student that his younger brother was, and did cause some alarm among those who knew him in years past.
Tamerlan Tsarnaev dropped out of community college, but became a leader in the boxing ring and aspired to be a U.S. Olympic boxer. But between 2009 and 2011, those around him began to notice that he was becoming detached.
He was arrested in 2009 for assaulting his girlfriend, and in 2010, he described himself as, "very religious; I don't have a single friend because I don't understand them."
While Dzhokhar was described by his fellow students as a "pothead," Tamerlan had jihadi videos posted to his YouTube account and was interviewed by FBI about suspected extremist ties in 2011, CBS News reported.
Gilberto Junior worked on the brothers' cars, and said Dzhokhar Tsarnaev appeared on Tuesday – the day after the bombing – to pick up a vehicle that was not ready. After Tamerlan's death and Dzhokhar's capture, Junior had no sympathy.
"He has to suffer. Dying is very easy. You're dead. You're gone," Junior told CBS News. "He's got to pay for what he's done."
The bombs the brothers allegedly planted detonated in the spectator area at the finish line on Boyleston Street. Killed were Martin Richard, 8; Krystle Campbell, 29; and Lu Lingzi, 23.
Authorities revealed the images to enlist the public's help finding the suspects on Thursday night. The same night, they were involved in a long night of crime.
A surveillance photo released by authorities of Dzhokhar Tsarnaev came from a gas station where the suspects stopped.
They then shot to death an MIT police officer while he was responding to a report of a disturbance, investigators said.
"They encounter an MIT police officer and rather than see, 'Is he going to follow us? Is he going to chase us?' it appears that they came up and engaged him, killed him in his police vehicle, took off," CBS News' Miller said.
The officer died of multiple gunshot wounds. The Middlesex County District Attorney's Office identified the MIT officer as 26-year-old Sean Collier, who had worked at MIT since January 2012.
From there, the two suspects carjacked a man in a Mercedes-Benz, keeping him with them in the car for half an hour before releasing him at a gas station in Cambridge, police said. The man was not injured.
Police say the Boston Marathon bombing suspects used their carjacking victim's ATM card before a gunfight with authorities.
Authorities said both suspects were in the Mercedes when they encountered police, and then hurled explosives and exchanged gunfire with officers.
Miller reported that the explosives thrown at officers was the same type of pressure cooker bombs that were used in Monday's marathon attack.
That's when police said a transit police officer, 33-year-old Richard Donohue, was seriously injured. Tamerlan Tsarnaev was also critically injured during the exchange with police and later died at a hospital, authorities said.
His brother, Dzhokhar, then got back into the car to escape, backing over his brother's body in the process, CBS News reported.
Five blocks away, Dzhokhar hopped out of the car and fled on foot, police said. Watertown residents reported hearing sounds of the intense gunfight and explosions at around 1 a.m. Friday.
Throughout the day Friday police urged Boston residents to stay in homes as the hunt for the bomb suspect continued. Residents in Watertown, Newton, Waltham, Belmont, Cambridge and the Allston-Brighton neighborhoods of Boston were also told to stay indoors.
At last, Mayor Thomas Menino tweeted "We got him" just before 9 p.m. on Friday.
Boston Police tweeted: "CAPTURED!!! The hunt is over. The search is done. The terror is over. And justice has won. Suspect in custody."
The Richard family released a statement early Saturday, following Dzhokhar Tsarnaev's capture.
"None of this will bring our beloved Martin back, or reverse the injuries these men inflicted on our family and nearly two hundred others. We continue to pray for healing and for comfort on the long road that lies ahead for every victim and their loved ones," the statement said in part. "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."
Authorities said Saturday morning that it is too early to speculate on whether Dzhokhar Tsarnaev could face the death penalty if convicted.
On Saturday night a pair of foreign nationals were arrested on immigration charges in New Bedford, Massachusetts The Associated Press reported.
An ICE spokesman would not comment on the people who were arrested or if they are connected to bombing suspect Dzhokhar Tsarnaev. The University of Massachusetts at Dartmouth student remains hospitalized after exchanging gunfire with police Friday.
ICE did not say whether they are suspected in any other crimes. A federal prosecutor's spokeswoman declined comment.
New Bedford police said federal authorities searched off-campus housing near the school Friday and took three people in for questioning. Police say Tsarnaev may have lived at the complex.
