A devastating fire broke out at a home in South Carolina overnight, killing four people inside – including two young children – who died trying to escape through a window.

Firefighters were called to the home on East 3rd Street in Gaffney at 1.40am and found the entire structure up in flames.

One person who was inside managed to escape, run across the street, and alert a neighbor who called 911, according to the Cherokee County Coroner Dennis Fowler.

However, not everyone inside the building got out as the structure blazed.

Willie Morris, 38, Dakeyia Shippy, 25, Mason Issac, four, and Jerekry McGill, seven months, died in the fire. 

The four deceased were struggling in their final moments and were attempting to get out of a window in the kitchen when they were overcome by the thick smoke.

Their bodies were tragically found together, on the ground in the rear of the home. 

Fowler explained that the person who escaped the fire and Morris were attempting to re-fuel a kerosene heater when the fire started. 

The coroner’s office, Gaffney Fire Marshall and State Law Enforcement Division are investigating the fatal fire.
