There are growing questions into the disappearance and eventual release of America’s only known prisoner of war, Sgt. Bowe Bergdahl. The now 28-year-old was released after five years in captivity by the Taliban after the United States agreed to release five Gitmo detainees.

General Martin Dempsey, chairman of the Joint Chiefs of Staff, has said he will not rule out investigating Bergdahl for desertion. The Army has reached out to former members of Bergdahl’s unit to question them.

On Facebook, Gen. Dempsey urged the public not to rush to judgment, saying Bergdahl is "innocent until proven guilty."

Meanwhile, former Defense Secretary Leon Panetta had this message for the White House about the released Taliban leaders: “There’s no question they’re dangerous guys and we have to make sure that they don’t re-enter the battlefield.”

Fox News has also obtained new photos showing the softer side of Bergdahl before he joined the military. They show then-teenage Bergdahl practicing ballet. His friends say he was not a pacifist and liked to shoot guns. They also say he joined the military to learn about other cultures.

Sherry Horton, owner of Sun Valley Ballet where Bergdahl used to dance, said, “Do I think his intentions were to desert? No, I don’t. […] There was lot of times here when things would get a little crazy all he wanted to do was walk into the forest or up into the hills and sit down and meditate for an hour.”

Bergdahl is currently receiving medical treatment in Germany.
