The elderly man found dead inside a van in the water near the Willtown Road boat landing Tuesday was the same person authorities had been searching for since Friday, the Charleston County Coroner's Office confirmed.

Leroy Wade, 81, of Johns Island had not been seen since leaving the Ralph H. Johnson Veterans Affairs Medical Center in downtown Charleston around 7 p.m. Friday. Wade drowned sometime between Friday and Monday, Charleston County Deputy Coroner Kelly Myers said.

A deputy on routine patrol spotted Wade's blue Dodge Caravan partially submerged in the Edisto River around 5:15 p.m. Tuesday, the Charleston County Sheriff's Office said. Authorities weren't sure what caused him to drive into the water.
