Two young girls and an adult man are dead after a huge explosion tore through a Nebraska biofuels plant, officials said Wednesday. 

The three had been missing since the Horizon Biofuels facility exploded Tuesday in Fremont, about 32 miles northwest of Omaha. All three were in the plant at the time of the explosion, Dodge County attorney Pam Hopkins told CBS News. On Wednesday, the focus at the scene "shifted from rescue efforts to recovery efforts," Hopkins said.  

All three bodies were recovered Wednesday night, officials said. 

The dead man was identified as Dylan D. Danielson, 32, of Columbus, Nebraska. Fremont Mayor Joey Spellerberg said earlier during a news conference that Danielson was an employee at the plant. The two children were waiting for him to go to a doctor's appointment. The girls were under 12, Spellerberg said. Officials said they would not be publicly identified.  

"My heart hurts," Spellerberg said. "It's a tragedy. We pray for every person involved."
