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 also said investigators did not expect to find any more bodies. When asked if there were any more people unaccounted for, Kistner deferred to local authorities.
West mayor pro tem Steve Vanek told NBC News' Gabe Gutierrez there is nobody unaccounted for.
Kistner said Saturday that authorities will begin removing four tanks from the plant in West as a precaution to safeguard those working there.
"That is necessary to make sure we can mitigate anything that's out there, remove material, and make sure that we have a safe environment for the investigators doing the work, that is the only reason that those tanks are being removed is so that we can continue on with the investigation phase," Kistner said.
Kistner said the tanks contain ammonium nitrate and anhydrous ammonia.
He said investigators still do not know where on the property the fire began.

Kistner said no other materials on the site pose any danger.
Sunday morning Union Pacific will begin work to repair the tracks damaged by the blast so that train traffic can continue through the area.
