A DNA testing process to identify the remains of the seven victims of the deadly fireworks warehouse explosion in the Esparto area is underway.

Seven people were "unaccounted for" in Yolo County's town of Esparto after several explosions at a fireworks warehouse resulted in a fire, officials said.

The explosion, which left seven people missing, started a wildfire and forced some cities and counties to cancel or postpone Fourth of July fireworks shows.
