No cause determined for Ampride blaze

Investigators have closed their probe of the Feb. 6 fire that destroyed the Ampride All-Round Travel Center without being able to determine what caused the blaze.

Fort Dodge Assistant Fire Chief Doug Ostbloom, who is the citys fire marshal, said the massive damage to the building at 3243 Fifth Ave. S. made it impossible to identify the cause.

Investigators from four agencies spent three days at the site trying to determine the cause of the fire.
