Authorities in Colleton County are trying to determine the cause of a fire at Myrtle Grove Plantation.
Fire Chief McRoy with the Colleton County Fire-Rescue says he believes the fire started from something related to the A/C unit located in the basement.
No foul play is suspected, but the occupants were having problems with the unit earlier in the day, McRoy added.
Colleton County Fire and Rescue shared a photo of the blaze late Wednesday as it ripped through the main house at the property.
The fire, in the 6900 block of White Hall Road, was so large the Sheldon Fire Department provided mutual aid.
Shortly after 7 a.m. Thursday, crews announced that all units had left the scene.
Fire crews say the fire took so long to put out because initial access to the home was blocked by low-hanging branches. Additionally, the home is in a non-hydranted area, so crews had to use water from a pond to fight the fire.
News 2 has learned that the house was occupied but no civilians were injured. A firefighter was treated and released from Colleton Medical Center after suffering a laceration during the fire.
News 2 will continue to update this story as it develops.
