SALT LAKE CITY (AP) — A 9-year-old boy is being treated at a Utah hospital a day after getting stuck underwater at a reservoir east of Park City. The boy and his two siblings were in their family’s truck on Monday when it slid down a boat ramp at Smith and Morehouse Reservoir, a popular recreation spot, while loading kayaks. Summit County Sheriff’s Captain Andrew Wright told KSL that three children were in the vehicle that slid in to the reservoir and two were able to escape — one swam to safety, while the other was rescued by her grandfather. The boy was flown in a medical helicopter to Primary Children’s Hospital in Salt Lake City.
