The Army psychiatrist suspected in a deadly rampage at Fort Hood has been charged in a military court with 13 counts of premeditated murder.
U.S. Army Criminal Investigation Command spokesman Chris Grey told a news conference Thursday at the Texas base that additional charges may also be filed against Maj. Nidal Malik Hasan.
"Today I've confirmed that U.S. Army Maj. Nidal Malik Hasan, a 39-year-old psychiatrist assigned to Darnell Medical Center here at Fort Hood, has been charged with 13 specifications of premeditated murder under article 118 of the uniform code of military justice," Grey said.
Hasan is suspected of killing 12 soldiers and one civilian in last Thursday's shooting spree at Fort Hood.
Officials said all autopsies have been completed, and the crime scene is still being processed. Investigators still believe he was the only gunman involved.
Investigators have not been able to speak with all witnesses, as some are still getting medical attention.
Hasan was shot and wounded by two police officers at the base, and remains in recovery at an Army hospital in San Antonio.
Investigators said that two police officers arrived at the scene and engaged Hasan, but right now they can't say who did what to take him down.
Hasan is under pre-trial restrictions while he continues to receive medical care. His attorney said he was read the charges at the hospital.
The officials said it is not yet decided whether to charge Hasan with a 14th count of murder related to the death of the unborn child of a pregnant shooting victim.
Meanwhile, Col. John Rossi said the Fort Hood Community continues to heal
"Gen. Casey called this event a kick in the gut. Which is so appropriate, but I will tell you at this time Fort Hood has gotten its breath back and we continue to move forward," Rossi said.
Rossi said all of those affected by the shootings are being offered support and said Fort Hood remains a safe place.
He added that upcoming events planned on post will go ahead as planned.
