A body found Friday in the Ashley River was confirmed to be that of a boater missing since last week.
Preston Guyse, 26, died from head trauma, the Charleston County Coroner's Office said.
Guyse reportedly launched his boat for a test run Sunday morning in the vicinity of Duncan's Boat Harbor and Landing.
The boat tilted, causing him to fall into the water, and a witness reported that the boat circled in the water and may have struck Guyse.
Rescuers had been searching the river for days.
