The body of a teen was found in the Yellowstone River on Saturday and an autopsy confirmed the victim as 15-year-old Robert Anthony Thompson.
Robby, a Box Elder County resident, was in Billings, Mont., with his mother, Julie Watts, and a 13-year-old sister, to meet with his step-father, a truck driver. The plan was to camp at a KOA campground but they arrived late Monday night and so camped in their car along the Dick Johnston Bridge near the river to wait for morning.
About 3 a.m., Robby left the family car and walked barefoot to the river along a bike path. He never returned. When the Yellowstone County Sheriff’s Department was contacted, there were concerns that he had run away. Investigators searched the riverbank and the water during the week, but were unable to local the missing teen. Robby’s father, Dale Thompson, traveled to Billings to assist in the search.
On Saturday, boaters discovered the body and notified authorities.
“The autopsy did not reveal any signs of trauma indicating foul play, and the cause of death is drowning,” Sheriff Mike Linder reported in a statement made Sunday. “There is no information to determine why or how Thompson ended up in the river.”
A friend said the parents of the victim are divorced. Robby spent his time between their homes in Portage and Willard.
