A sad ending to the story of country singer Craig Morgan's son, who went missing after a boating accident Sunday and whose body has now been found, Tennessee authorities confirmed Monday night. Jerry Greer, 19, was tubing on the Tennessee River near Kentucky Lake with a friend when they fell into the water. Greer was wearing a life jacket, but never resurfaced, the Tennesseean reports. "It was just as simple as hitting a wave and turning over and not coming back up," Humphreys County Sheriff Chris Davis told reporters Monday, per People. "There's always hazards in the area that could've contributed to this accident." (More Tennessee stories.)
