 -- Jerry Greer, the son of country singer Craig Morgan, was found dead in the waters of Kentucky Lake in Humphreys County, Tennessee, officials confirmed late Monday.

The search for Greer had gone from rescue to recovery, after the Tennessee Wildlife Resources Agency brought in military-grade sonar to search Kentucky Lake.

Jerry Greer, 19, never resurfaced after a tubing accident there on Sunday afternoon.

In a statement via his publicist, Morgan said his "family is grateful for everyone's support and prayers and requests privacy during this difficult time."

The teen recently graduated from Dickson County High School in the Tennessee town where his father was raised.

Morgan, 51, is best known for his hit singles "That's What I Love About Sunday," "International Harvester" and "Bonfire."

The singer, who regularly performs on military bases in the United States and abroad, is a father of four.
