FREMONT, Neb. The Tuesday explosion at a wood pellet manufacturing plant in Fremont that killed a worker and two young girls is believed to have been caused by a dust fire, the Nebraska fire marshal said Thursday.
The Nebraska State Fire Marshal's Office said in a press release that a preliminary investigation shows an accidental dust explosion occurred during the manufacturing process at the Horizon Biofuels plant, 950 S. Union St. The blast shook nearby buildings, crumbled much of the plant and sparked a fire that burned for two days.
"Additional investigation efforts are currently impeded due to the instability of the structure," the release said.
The building is still smoldering, but the scene of the explosion has stabilized, the Dodge County Sheriff's Office said Thursday afternoon.

South Union Street in Fremont remains closed Thursday around Horizon Biofuels following a deadly explosion.
