WEST, Texas - A state fire official says there's no sign of criminal activity in the explosion of a fertilizer plant in Central Texas that killed 14.
Assistant State Fire Marshal Kelly Kistner said Saturday that authorities will begin removing four tanks from the plant in West as a precaution to safeguard those working there. Kistner said the tanks contain ammonium nitrate and anhydrous ammonia.
He said investigators still do not know where on the property the fire began.
A fire touched off a massive explosion Wednesday at the West Fertilizer Co., destroying homes, schools and a nursing home within a several-block area of the site.
Kistner said no other materials on the site pose any danger.
