Tyler James McGill, born in 1996, faces felony aggravated assault and battery and possession of a deadly weapon with unlawful intent, plus three misdemeanor battery counts. The incident occurred July 4 in Medicine Bow-Routt National Forest southeast of Rob Roy Reservoir. According to an affidavit, McGill confronted campers after a dirt bike rider kicked up rocks near his site, then fought three men, took a firearm from one and pointed it at another, and later retrieved a second gun from his vehicle. A round was fired during the struggle; no one was hit. A preliminary hearing is set for July 14.
