The Army is formally charging psychiatrist Nidal Hasan with 13 counts of murder in last week's Fort Hood shootings.
The 39-year-old will face justice in a military court by a jury of Army officers. Additional charges are possible, said Chris Grey, spokesman for the Army Criminal Investigation Command
Hasan is accused of opening fire on soldiers Nov. 5 as they awaited pre-deployment examinations last week. Thirteen people died in the massacre and 29 were injured.
Officials have yet to decide if Hasan will be charged with a 14th count of murder for the death of an unborn child from a pregnant shooting victim.
If found guilty, Hasan could face the death penalty by lethal injection.
Meanwhile, questions remain over why he was allowed to continue serving in the military despite his alleged jihadist views and poor work performance.

Another question at the center of it all is how Hasan, a man known by the Joint Terrorism Task Force to have ties to al Qaeda, could have legally acquired a pistol.
"We have not at all improved coordination between those who watch terrorism and those who monitor who can buy a gun," said Charles Schumer. "Why... wouldn't they allow this information to go to the anti-terrorism authorities?"
The FBI is also on the defensive after accusations of insufficient follow-up on the gunman's link to a radical imam.
"Because the content of the communications was explainable by his research and nothing else derogatory was found, the JTTF concluded that Major Hasan was not involved in terrorist activities or terrorist planning," FBI officials said in a statement.
The one person who could possibly shed more light on the brutal attack is Sergeant Mark Todd-- one of two police officers on the scene-- but he is not talking.
Despite the finger pointing, one thing is clear from pictures of Hasan's apartment-- he wasn't planning on returning any time soon.
