About 11:15 p.m. Monday the Lakeview Volunteer Fire Department was dispatched to a fire call at Collin's residence, a camper located at 541 Spruce Pine Road in an unincorporated area of western Hawkins County north of Mooresburg.
Lakeview VFD Assistant Chief Curtis Dean said the first firefighters to arrive on the scene found the camper fully engulfed in flames.
"By the time we got there they had notified us and told us there was possibly someone in it," Dean said. "When we got the fire under control, we pulled the side wall out of it trying to put the rest of the fire out, and that's when we saw the body.
"The structure was pretty much already gone when we got there. The roof was gone, and the front wall was about burned out of it when we got there."
Dean said he doesn't know how the fire started, and it may be impossible to determine the cause because the fire destroyed everything.
Sheriff Roger Christian said Tuesday his department has established that Collin lived in the camper alone, but other than that there wasn't much information available.
Christian said there is no reason at this time to believe that the fire is suspicious or was intentionally set.
He added, however, that Collin's body would be sent to the Quillen College of Medicine in Johnson City to determine cause of death.
