Despite the guilty verdict, Matthews was not taken into custody.
On July 3, 2017, in Utah County, a Pleasant Grove resident was riding his mountain bike down the Grove Creek Canyon Trail when he came upon Matthews who was walking on the trail, wearing only shoes and a small back pack. The biker, coming up from behind, could see Matthews' naked buttocks and genitals. As the biker passed, Matthews turned and said "Hi," fully exposed and standing in the middle of the trail.
The biker called police to report the incident. Pleasant Grove police officers arrived at the trailhead and spoke with Matthews as he exited the trail. At the time that the officers approached Matthews, he was clothed but admitted to police that he had taken his clothes off to get in the creek and had not put them back on for his hike out of the canyon. Matthews also admitted to officers at that time that he was a registered sex offender.
Robert Byers Matthews will be sentenced on May 10, 2018 in the Fourth District Court and faces a maximum sentence of 0-5 years in the Utah State Prison. Until sentencing, the Honorable Judge Christine Johnson ordered that Matthews have no unsupervised contact with children and no internet use other than what is required for his employment.
