ROSSVILLE, WALKER COUNTY (WRCB) -- A Rossville man has been cleared in the explosion that destroyed his home.
Ricky Bethune was in Michigan when a blast leveled the home he rented on Mission Ridge Road in November of last year.
State arson investigators say gasoline vapors ignited the explosion.
They believe someone either left a gas can open intentionally, or poured gasoline on the floor and a spark ignited the fumes.
Walker County fire investigators tell Channel 3, Bethune passed a lie detector test.
They've asked two other men to a polygraph, but only one has agreed.
