The documents say C.F. told the investigator Clark hit him in the ribs, then asked the victim to name the capital of Thailand, responded "Bangkok" and hit him in the groin before the man could respond.

"C.F. had long hair on his head, facial hair and he is half-Asian," court documents note.

Later during the bonfire, Clark is accused of becoming aggressive toward the man again and calling him "an ISIS" while brandishing his gun. C.F. reported a friend telling him to flee.

"He said as he ran away he was '100% positive he was gonna start shooting,'" the documents say.

Clark's private attorney, Mathew Johnson, said the agent failed to speak with his client and other witnesses.

"My client was very surprised that charges were filed without an investigator talking to him," Johnson said.

Anastasia Burton, deputy communications director for the Montana Department of Justice, said she could not comment "as the case is still under review."

An interview with Clark "would include self-defense claims," Johnson said, adding that he looks forward to proving his client's innocence during trial.
