Human remains were discovered by first responders after they extinguished a structure fire in Aiken County on Monday night. 

Around 11:30 p.m., Aiken County Sheriff’s Office deputies, the Couchton Fire Department and six other fire departments responded to Alicia Drive in Couchton after receiving a 911 call for a residential fire.

Upon their arrival to the trailer, it was found to be fully engulfed.

Firefighters found human remains inside the residence once the fire was extinguished, the sheriff's office reported. 

Due to extensive thermal injuries a positive identification has not been made, Aiken County Coroner Darryl Ables said.

Sheriff’s investigators and the Aiken County Coroner’s office responded and are working to determine the origin and cause of the fire.

An autopsy is scheduled for Friday morning in Newberry.

The investigation is ongoing.
