Boston Marathon Bombing Suspect Dzhokhar Tsarnaev, Formally Charged in Hospital Room, UPDATES: Information About Investigation

Dzhokhar Tsarnaev, 19, has been in the hospital with multiple gunshot wounds and officials continue the investigation of the Boston Marathon bombings within the hospital where he is located and without.

Tsarnaev had been in serious condition since he was captured wounded and hiding in a tarp-covered boat located in a boatyard in Watertown on Friday night, according to CBS.  On Tuesday, his condition was upgraded to fair, according to the U.S. attorney's office.

Tsarnaev admitted to authorities on Sunday that it was indeed he and his brother who were behind the Boston Marathon bombings, according to a senior law enforcement official, reports The Boston Globe. 

He made his admissions during an interview with FBI agents at Beth Israel Deaconess Medical Center, where he is being treated for multiple gunshot wounds.  The Globe reports that he claims that he and his brother acted alone in the attack, and that his brother followed a radical, anti-American form of Islam largely due to opposition toward US actions in Iraq and Afghanistan.

His confession came before he was read his rights, however, the FBI cites that there is a "public safety exception," in which "failure to administer Miranda warnings does not, standing alone, make a confession involuntary in violation of the Constitution," according to The Globe.  

The Globe reported that authorities are not worried about the initial admissions being thrown out also because they have a very strong witness who had been abducted by the Tsarnaev brothers last Thursday evening in Allston.  The carjack victim told police that the brothers pointed guns at him and said, "We just killed a cop. We blew up the marathon. And now we're going to New York. Don't [expletive] with us," according to The Globe.

The carjack victim also told officials that the bombers repeatedly told them that they were going to New York and that they used his ATM card to get cash for the trip, The Globe reports.  Investigators have been trying to determine if they had resources in New York.  However, "If they had accomplices in New York, you'd think they would have had an established contingency plan to get down there to them, and wouldn't be shooting cops and carjacking cars to steal ATM cards to finance their escape," an official told The Globe.

Tsarnaev is cooperating with authorities, who have not found any evidence of ties to major terror organizations, according to CBS News correspondent Bob Orr.  He has been communicating to authorities through writing since a wound to his neck has left him unable to speak.

Federal prosecutors announced terrorism charges against Tsarnaev on Monday, citing the use of a weapon of mass destruction and the malicious destruction of property, according to the Washington Post.  There is a possibility that he may face the death penalty.  However, the Boston Herald reports that Tsarnaev is likely to avoid the death penalty due to his age and lack of a past criminal record.

Some congressional Republicans have asked that Tsarnaev be classified as an "enemy combatant," but White House press secretary Jay Carney rejected that approach on Monday due to the fact that he cannot be tried in a military commission under federal law because he is a U.S. citizen, according to The Post.  "We will prosecute this terrorist through our civilian system of justice,'' Carney has said at a White House news briefing.

Investigations concerning the bombing itself continue as well.  The Boston Globe reports that an official at a New Hampshire fireworks store said Tamerlan Tsarnaev had bought fireworks there in February and has speculated that the brothers were interested in the explosives inside.

Senate Intelligence Committee member Richard Burr, R-N.C., in Washington said that the is "no question" that Dzhokhar's older brother Tamerlan, 26, who in now deceased, was "the dominant force" behind the attacks, according to The Huffington Post.

Meanwhile, in Boston, businesses and schools have reopened and residents are trying to resume their normal lives despite the tragedy that occurred there only a little over a week ago.  About 50 people remain hospitalized since the bombing, reported The Huffington Post.
