Firefighters and law enforcement responded to a fully involved structure blaze Friday night on the 400th block of Old Valley Road in Harriman. Crews arrived around 9:30 p.m. to find a camper trailer on fire.

Officers announced today that 39-year-old Cynthia Renee Osbourne died in the fire.

Authorities say 39-year-old David Lee Pollard was also inside the camper. He was taken to an area trauma center for treatment of serious injuries.

District Attorney General Russell Johnson said a preliminary investigation indicates the fire may have been intentionally set by Osbourne.

The case remains under investigation by the TBI and Roane County Sheriff’s Office.
