Dzhokhar Tsarnaev is being held at Federal Medical Center, Devens, behind a steel door and tight security, where he faces the death penalty for allegedly detonating two deadly bombs at the Boston Marathon on April 15. FBI

Boston bombing suspect Dzhokhar Tsarnaev was arraigned Monday at his bedside at a Boston hospital on charges related to the marathon blasts and subsequent shootout that resulted in four people being killed and 180 people injured.

Further, the charges were sealed, according to WCVB. Meanwhile, White House Press Secretary Jay Carney said Tsarnaev, 19, won’t be tried as an enemy combatant, as some Republican senators had hoped.

Tsarnaev reportedly suffered gunshot wounds to his throat and neck, and authorities believe he may have sustained the throat wound after putting a gun in his mouth and pulling the trigger. Initial reports suggested Tsarnaev suffered both injuries during an early Friday morning shootout with police involving improvised explosive devices.

Tsarnaev’s older brother, Tamerlan Tsarnaev, 26, was killed in the shootout and suffered so many wounds that doctors could not tell which injury caused his death. The brothers had hid in the region since Monday’s bombings. After the FBI released photos of the then-unidentified suspects Thursday night, the brothers allegedly hijacked a car, shot and killed MIT officer Sean Collier and engaged in the shootout with police, hurling IEDs at responding officers.

Authorities from an elite team of federal investigators have been questioning Dzhokhar Tsarnaev at Beth Israel Deaconess Medical Center. However, due to Dzhokhar Tsarnaev’s throat injury, he is unable to speak. Instead, he’s been communicating with investigators by writing.

Interrogators want to know, among other questions, if there was anyone else involved in the planning or execution of the bombings and whether there are more explosive devices hidden around Boston, among other questions, ABC News reported.

The bombings killed three people, including 29-year-old restaurant manager Krystle Campbell of Arlington, Mass., whose funeral is Monday . Also killed were Martin Richard, 8, of Dorchester, Mass., and Chinese graduate student Linghzi Lu.
