Seventy-three year old Sheldon Sullivan died in a fire this morning at a trailer park in Lincoln according to Lewis and Clark County Coroner Mickey Nelson.
By the time firefighters arrived the house was completely engulfed in flames, and cold temperatures made it difficult to put out the blaze.
Sullivan's body has been taken to the State Crime Lab in Missoula for further investigation. The cause of death has yet to be determined, but reports say it is likely smoke inhalation or super-heated air. The matter is still under investigation.
