The focus of litigation stemming from the April 17 explosion at the West fertilizer plant may change, after news that Adair Grain Inc., doing business as West Fertilizer Co., holds only a $1 million liability insurance policy.

"You are going to see focus change from ‘How did this explosion occur?’ to ‘Who could have prevented it?’ And why was so much ammonium nitrate at this plant? Who was storing it there?" says Randy Roberts, a partner in Roberts & Roberts in Tyler. He represents two plaintiffs, each of whom has filed a personal-injury suit in the aftermath of the blast.
