MCCLELLANVILLE — A 68-year-old man died inside his single-wide mobile home after it caught fire early Christmas morning, authorities said.

William Winbush was home alone at 8572 Old Georgetown Road when the first emergency calls went out at 5:39 a.m., Charleston County Chief Deputy Coroner Judy Koelpin said.

An autopsy showed that Winbush died of smoke inhalation. His wife lived with him but was visiting relatives at the time.

The Awendaw Fire Department doused the flames quickly but remained on the scene several hours to keep an eye on a leaky propane tank and to assist the Charleston County Sheriff's Office with the investigation, Battalion Chief Barney Howard said.

The cause was not immediately available.

Sheriff's investigators found no signs of foul play, Maj. John Clark said.

On Tuesday night, a fire heavily damaged an abandoned house in the Liberty Hill neighborhood, the apparent result of somebody trying to keep warm, the North Charleston Fire Department said.

Crews responded to the one-story wood house at the corner of Nesbit Avenue and Lester Street at 6:28 p.m. and had the fire under control within about 10 minutes, Battalion Chief Joseph Munn said.

Firefighters think the flames originated in the fireplace, though whoever started them left the area before the first firetrucks arrived.

On Monday night, a fire destroyed a house near Clements Ferry Road and left a family homeless.

Firefighters from the Charleston, Cainhoy and Huger rural fire departments responded to 810 Jalap Lane about 7 p.m., said Mark Ruppel, the Charleston Fire Department's public information officer.

There were no injuries and the cause remained under investigation.

The Carolina Lowcountry Chapter of the American Red Cross offered financial assistance to replace food and clothing, and arranged for temporary housing, a release says.

Volunteers also made referrals to other local organizations to help with long-term recovery.
