The world is waiting for answers from 19-year old Dzhokkar Tsarnaev.

However, according to authorities, he is in no condition to be interrogated.

Tsarnaev remains hospitalized with a gunshot wound to his neck.  A justice department official says he’ll face federal terrorism and possibly state murder charges.

A big question for investigators is whether Tsarnaev tried to commit suicide as police were closing in on him under the tarp of that boat in Watertown, Mass.  Investigators say it is possible the 19-year old put a gun in his own mouth and pulled the trigger as SWAT teams were moving in closer.

CNN reported he is communicating with investigators.  He cannot speak, but he is nodding his head to respond to questions.   Authorities have not revealed what he is communicating.

Boston’s Police Commissioner says there could have been more attacks if authorities hadn’t stopped Tsarnaev and his older brother, Tamerlan.

“We have reason to believe, based upon the evidence that was found at the scene — the explosions, the explosive ordnance that was unexploded and the fire power — that they were going to attack other individuals,” Davis said on CBS News’ “Face the Nation.”

In 2011, the FBI says it interviewed Tamerlan after Russian authorities alerted the U-S government.  The elder Tsarnaev then made a six-month trip to Russia in 2012, but his exact whereabouts and activities are unclear.

“The ball was dropped in one of two ways,” said Senator Lindsey Graham.   “The FBI missed a lot of things is one potential answer, or our laws do not allow the FBI to follow-up in a sound, solid way.”

Tamerlan’s YouTube channel linked to a video featuring a well-known jihadist who was killed by Russian forces last December.  There is no evidence Tamerlan was associated why any international jihadist groups.
