Morgan's publicist Cindy Hunt says crews are searching for Jerry Greer in Humphreys County, west of Nashville. Hunt says the family is grateful for support and prayers, but is requesting privacy "during this difficult time."
Sheriff's Office Chief Deputy Rod Edwards in that county told local media that the search began around 4 p.m. Sunday near a marina. Edwards says two teenagers were tubing when they had an accident and one teen didn't surface. Both were wearing life jackets.
The Sheriff's Office requested assistance from rescue organizations across the state. About 50 boats joined the search. Authorities say crews were using an underwater vehicle to scan a search on the river where the water is up to 15 feet deep at points.
