The company indicated that multiple people died in the incident three days before the Fourth of July, but officials have not issued a determination.

A number of municipalities across Northern California have put their Fourth of July fireworks shows on hold after the explosion at a fireworks warehouse in Esparto. Cal Fire says seven people are unaccounted for after the massive explosion at Devastating Pyrotechnics on Tuesday.

Explosions continued more than 24 hours after the blast caused several spot fires and scattered large pieces of debris across a wide area, officials said.
