The Texas State Fire Marshal’s Office and the Bureau of Alcohol, Tobacco, Firearms and Explosives will announce the results of their weeks-long investigation of the deadly April 17 explosion at West Fertilizer Co. later Thursday, but a published report Thursday morning says they have identified three possible causes.
Quoting an unnamed government official, The Dallas Morning News reported Thursday morning that investigators traced the fire that led to the powerful explosion to a golf cart, the fertilizer and seed building’s electrical system or an intentional act.
Investigators will officially list the cause as undetermined, the newspaper reported.
Officials have scheduled a news conference for late Thursday afternoon in West to announce the results.
Last week State Fire Marshal’s Office spokeswoman Rachel Moreno said investigators had determined that ammonium nitrate stored at the plant is what exploded, but not what touched off the ammonium nitrate.
Moreno said a spot that is now a 90-foot-wide crater was where the ammonium nitrate was stored.
