"He said some strange things, like, 'I could get lost in those mountains,' which, at the time, that doesn't really strike you as someone who is going to leave their weapon and walk out."
Vierkant said he believes it's paramount that an investigation determine whether Bergdahl deserted or collaborated with the enemy.
"It shouldn't even be a question of whether, it should question of when," he said.
