Friends and family have confirmed to First Alert 6 the identities of the two girls killed in Tuesday’s explosion at a biofuels plant.

Hayven's family confirmed her father was the man killed in the explosion, 32-year-old Dylan Danielson of Columbus. Fayeah's family confirmed Dylan was her father and Hayven was her half-sister. Danielson worked at Horizon Biofuels, and Nebraska state fire investigators think an accidental dust fire caused the explosion.
