Three people tied to last year's deadly fireworks explosions in Esparto, California have been arrested, including a Yolo County sheriff's lieutenant, his wife who worked at the sheriff's office, and the owner of a fireworks company that operated at the site. The explosions killed seven people and destroyed several buildings.

Why it matters

The Yolo County Civil Grand Jury found that top county officials were aware of illegal fireworks operations at the Esparto explosion site for years but failed to take enforcement action, directly leading to the deadly incident. This case highlights issues with oversight and accountability around hazardous operations in local communities.
