A Sunday morning blaze destroyed a shed on U.S. 287 just north of the intersection with Farm Road 1810.
The fire consumed the metal structure along with a truck, fifth-wheel trailer and work equipment parked under it.
Decatur firefighters battled the blaze toned out at 6 a.m. Alvord, Bridgeport and Paradise firefighters provided mutual aid and water.
“There was heavy fire upon arrival,” said Decatur Fire Captain Nate Mara. “We had it knocked down and under control by the time first mutual aid arrived.”
There were no injuries.
Wise County Deputy Fire Marshal J.C. Travis said Monday the fire is being considered “suspicious” and the investigation remains open.
“We’ve ruled out all the accidental causes,” Travis said. “There is an ongoing investigation.”
He added that a final determination could hinge on lab results that may take up to four weeks.
