On April 18th, interpretive rangers reported that five visitors on a guided cave tour had repeatedly left the designated cave trails, had touched and/or removed cave features, and were acting disorderly. Ranger Josh Clemons and FTEP trainee Jake Olson contacted them and found that two had cave rocks in their possession. All five were detained and escorted to their vehicle, which was in the visitor center parking lot. The rangers saw drug paraphernalia and a rifle barrel sticking out of a backpack in plain view in the bed of the truck. A search of the truck led to the recovery of an ounce of marijuana, two vials containing a white/yellow powder that tested positive for cocaine, more drug paraphernalia, two handguns (one with a suppressor), and two assault rifles. All the firearms were loaded and ready to fire. The owner of the truck was identified as Nathan Jones of Mississippi. He was arrested and charged with unlawful possession of a firearm by a person who is an unlawful user or addicted to a controlled substance, possession of a controlled substance, possession of drug paraphernalia, and a violation of the CFR regulation on preservation of natural resources. Chris Wright, who rangers were unable to identify at the scene, was also arrested and charged with the latter. The three other members of the group were identified and released after the field investigation. On April 21st, Jones and Wright appeared in federal district court. Wright testified that he was a habitual user of marijuana and that he possessed/used marijuana and cocaine just prior to his arrest and also possessed a loaded firearm. The judge entered a $25,000 bond on Wright. Jones was released on a $25,000 unsecured bond pending trial.
