Soldiers participating in a training exercise on a Mississippi military base heard noises they believed were gunshots Tuesday and Wednesday.

But the man who apparently produced the noises told authorities Wednesday after he was arrested that it only his battered pickup backfiring.

Still, Alfred Baria Sr. remains in jail, charged not only with misdemeanor charges of disturbing the peace but also felonies. That's because police found guns at his house and Baria is barred from having them after a previous felony conviction.

Baria's son said he understood concerns about military safety at Camp Shelby Joint Forces Training Center, but said he felt officials were overreacting.

Local and state authorities say they're still investigating Baria's story and haven't ruled out further charges if they conclude he was shooting at soldiers.
