Dzhokhar Tsarnaevt is conscious and answering FBI questions in writing after shooting himself through mouth

Dzhokhar Tsarnaev, The alleged Boston Marathon bomber is now awake and responding to questions in his hospital bed. Law enforcement sources told ABC News that Tsarnaev is responding sporadically in writing to questions from investigators regarding other cell members and other unexploded bombs .

During the manhunt for him, the 19-year-old who escaped from the police in a Mercedes SUV, ran over his brother, Tamerlan who was was handcuffed and lying on the ground. Police said that is why Tamerlan died.

Later on Friday night, as SWAT officers and federal agents closed in on the boat where he was hiding in Watertown, Massachusetts, Dzhokhar shoved his pistol in his own mouth and pulled the trigger. However, instead of killing him, the bullet simply tore through his neck.

Police sources said the investigators are looking into the possibility that Tsarnaev and his older brother Tamerlan had a suicide pact so that neither of them could be taken alive and put on trial. Authorities believe that may be why Dzhokhar likely killed his brother when he ran over him.
