Investigators Searching for Cause of Fertilizer Plant Explosion

Formal death count still stands at 12


Investigators searched for clues on Friday to the cause of a Texas fertilizer plant explosion that obliterated sections of a small town and killed at least 12 people, including volunteer firefighters who raced to the scene to douse a blaze.

There was no indication of foul play in the blast at West Fertilizer Co, a privately owned facility that authorities said had not been inspected in two years.

The farm supply business, located in a residential area of West, had told a state agency that it stored potentially combustible ammonium nitrate on the site.
