A Berkeley County man trying to keep warm with a charcoal grill in a bedroom probably died of carbon monoxide poisoning early Thursday morning, Coroner Bill Salisbury said.

The man was identified as Audiel Lopez-Marroquin of College Park Road. An autopsy will be conducted, but all signs point to carbon monoxide poisoning, Salisbury said.

His wife called for help and was taken to a hospital for treatment, Salisbury said.
