According to the report, McGonegal first made eye contact with the off-duty, civilian-clothed ranger as he pulled his Jeep into a parking lot at Edgewater. The ranger said he walked to a trail, looked back, and saw McGonegal had rolled down his window and was tapping on the door frame, waving at the ranger.
The ranger wrote that he walked out of sight, then returned after two minutes to find McGonegal pulling out of his parking spot. McGonegal returned when he saw the ranger, the report said.
The two men began talking, and when the ranger asked McGonegal if he wanted to go for a walk, the priest declined and said he knew of people who had been arrested by park rangers, the report said.
The ranger turned down an offer to get in McGonegal's Jeep, and then the priest suggested that they go to his nearby home, the ranger wrote.
The report also said McGonegal was touching himself while the men were talking.
The two then shifted the conversation to what McGonegal wanted and how much he would pay, the report said, before McGonegal exposed himself and the ranger arrested him.
