The body of Reggie Puckett, 43, was pulled from the Reservoir Thursday morning.
Authorities say he was tossed overboard and drowned Wednesday night. Puckett was a passenger onboard a boat. The driver says he crashed into something, tossing Puckett into the water. An immediate search had to be called off because it was too dark.
Investigators say they don't know what led up to the crash or what caused it.
Puckett lived in Florence with his wife.
