Arson not ruled out in fire that caused West, Texas, blast

   
The cause of a fire that triggered a massive explosion at a West, Texas fertilizer plant has been ruled undetermined, and investigators have not eliminated the possibility that the fire was set intentionally, state and federal officials said on Thursday.    

Robert Champion, a special agent in charge at the Bureau of Alcohol, Tobacco, Firearms and Explosives, said that while authorities could not rule out arson, they also could not eliminate the plant's electrical system or a golf cart at the plant as potential causes.    

The West Fertilizer Co facility, which supplied fertilizer to area farmers, exploded on April 17 about 20 minutes after a fire was reported at the plant. The blast - actually, what officials described Thursday as a pair of blasts separated by milliseconds, - killed 14 people and badly damaged a residential area including an apartment building, nursing home and school.    

The investigation, which cost the ATF more than $1 million, involved pursuing 280 leads, interviewing 500 people, and sifting through 300,000 pounds of corn by hand to collect evidence, Assistant State Fire Marshal Kelly Kistner said.         

The scene investigation is complete, but the overall probe into the fire is continuing, State Fire Marshal Chris Connealy said. The fire marshal's office is also investigating the deaths of the first responders.    

Most of the dead were firefighters and paramedics who responded to the initial fire. Some 200 people were injured.         

The plant stored anhydrous ammonia, a liquid fertilizer, as well as ammonium nitrate, a dry fertilizer that can ignite in certain conditions. Ammonium nitrate was an ingredient in the device used in the 1995 Oklahoma City bombing.    

Investigators had previously ruled out possible causes including the weather, natural causes, a fire within the ammonium nitrate bin, a rail car containing ammonium nitrate and anhydrous ammonia - another fertilizer component.    

Investigators believe the fire started somewhere in the 12,000-square-foot (1,100-square-meter) fertilizer and seed building. They confirmed last week that ammonium nitrate stored at the plant detonated in the explosion.    

State officials last week announced a criminal probe into the explosion.    

Bryce Reed, a paramedic who was among the first responders at the explosion site, was arrested last week for possession of pipe bomb components. He was indicted by a federal grand jury in Waco on Tuesday and pleaded not guilty to the charge on Wednesday, federal prosecutors said.
