A large illegal fireworks display, placed in the street by the homeowner, failed and began misfiring toward the home where the child was, police 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.

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.
