Williamsburg County Sheriff Michael Johnson says they got a call about 1 p.m. Sunday from Georgetown County deputies in reference to a note found at a suicide.
The note led them to a burned home on Sleepy Prong Road in the Andrews community, Sheriff Johnson says.
They found a body burned beyond recognition inside the house, Johnson says.
They believe the body is that of a man.
There is no cause of death, but they are treating the fire as a homicide.
An autopsy has been performed. Deputies are waiting for the results.
The State Law Enforcement Division has been called in to help in the investigation.
