BOISE -- Officials at a U.S. military hospital in Germany say Sgt. Bowe Bergdahl is showing new signs of recovery, three days after being released from captivity in Afghanistan.
Bergdahl is still at Landstuhl Regional Medical Center where he remains in stable condition and is now participating in his health care.
Officials also say that Bergdahl will be briefed formally as doctors continue examining him.
The reintegration process, which determines when Bergdahl may return home to Idaho, will happen at his own pace.
From Germany, Bergdahl will go to Brooke Army Medical Center in San Antonio, Texas.
The U.S. Army is now preparing to launch a full high-level investigation into the circumstances around Bowe's disappearance.
The Army will be looking into Bowe's conduct leading up to his capture to determine whether he will face any criminal charges, including desertion..
Years ago, the Army found he did intentionally walk away from his post, but now questions remain as to whether he should be charged.
We talked with a former military attorney about how this process will unfold.
In Bowe's case, in order to find him guilty of desertion, they would have to find that he was permanently going to leave the service, said former JAG officer Jeff Smith.
But first, the Army will conduct interviews with those who served with him in Afghanistan, and waiting until Bowe is mentally able to give his own account.
Apparently he had written letters and made comments to other people in regard to his dissatisfaction with the military, or our military actions in Afghanistan, but the difficulty comes in to play with trying to determine his state of mind, said Smith.
Smith says it's all part of the uniform code of military justice, established in the early 1940s.
It's a mechanism where the military handles its own kinds of cases, he said.
Smith explains once the investigation is complete, the convening authority will decide whether to take an administrative route -- involving Bowe's discharge from the military without punishment or take judicial action, pursuing criminal charges.
If Bowe does face charges like desertion, it could eventually end in a trial.
And if he's convicted, the maximum penalty for desertion is dishonorable discharge and up to five years confinement. Military experts say if it's during war time, the punishment could be death.
I don't think the military has declared it unconstitutional, but I don't think they've put anybody to death, but the charge does carry confinement and that would be a decision made by the convening authority as to what sentence would be imposed, said Smith.
Smith says officials would also look at the resources used and lives lost in the search for Bowe.
When it comes to the death of the other soldiers, they have to make a determination whether or not there is some sense that Bowe would have recognized that he was putting himself in the position that other people would be trying to find him, said Smith.
Smith says this could be a lengthy process, and it's still unknown exactly which government officials, at which level, will be investigating.
He also said there is a possibility that if he's convicted, Bowe's sentence could be shortened since he did spend five years in captivity.
