Investigators are not yet sure of the cause of a mobile home fire south of Agency that happened overnight.

The fire was originally reported as an explosion, Buchanan County Sheriff Mike Strong confirmed that Wednesday but fire officials say otherwise.

A Sergeant with the Sheriff’s Department called to notify the Sheriff of the explosion overnight.  A fire inspector is said to be on the scene today, he said.

The north end of the structure was on fire when fire crews arrived, South Central Buchanan County Fire Chief Dennis Johnson said.

“Were talking about a double wide mobile home that had a gable roof on top of it of so you had literally two roofs and fire being in-between made it challenging to put out,” He said

It was reported just after 6:30 Tuesday evening at 6447 South East Tillery Road.

Some rumors circulated that it may be drug related.  The Drug Strike Task Force is aware of the explosion but knew no other details as of Wednesday afternoon, officials there said.
