RIVERTON — The 15-year-old Evanston boy who died in July during a tubing accident at Morton Lake was not intoxicated at the time, toxicology testing showed.
Dagon L. McWhorter, 15, died at about 1 p.m. July 24 of asphyxia due to fresh-water drowning, according to a report from the Fremont County Coroner’s Office.
Toxicology testing revealed no relevant substances, the report states.
The youth’s body was retrieved from the lake July 26, but law enforcement initially responded at about 1 p.m. July 24 to a report that the boy was “struggling in the water while trying to swim ashore.”
He had been tubing with other teens near the Sunrise Recreation area boat ramp on the north side of the lake, according to a press release from the Fremont County Sheriff’s Office.
First responders at the scene were unable to find the teen July 24, and on July 25 crews and divers spent “the entire day” grid-searching the portion of the lake in which he was last seen, Fremont County Sheriff Ryan Lee said.
The July 25 search also was fruitless, so Lee said more search crews were deployed July 26, along with “additional sophisticated sonar equipment from the Sublette County Sheriff.”
The body was recovered just before noon July 26 in about 45 feet of water. Lee said the operation was completed “without incident.”
