Horry County, SC – Authorities say a couple have died in South Carolina after using a generator inside their home during Florence.

Horry County Chief Deputy Coroner Tamara Willard said 63-year-old Mark Carter King and 61-year-old Debra Collins Rion were killed by breathing in carbon monoxide.

Willard said in a statement their bodies were found in a Loris home Saturday afternoon, but they likely died the day before as the heavy rains and winds from former hurricane-turned-Tropical Depression Florence were moving onshore.
