WEST, Texas – A fire that led to a devastating explosion a month ago at a fertilizer plant in this small town north of Waco remains undetermined, state and federal investigators said at a news conference Thursday.
Fourteen people were killed in the April 17 explosion, more than 200 were wounded and scores of homes were damaged and destroyed.
Hundreds of investigators have combed the facility site, which remains closed off.
State Fire Marshal Chris Connealy said the cause of an initial fire, in the seed room at the facility, could not be ruled natural, incendiary or accidental, thus the undetermined classification.
He said investigators had not ruled out an intentionally set fire, a malfunction involving the 120-volt electric system at the site, or a battery-powered golf cart parked in the seed room.
