After what happened in Esparto and the large response that followed, CBS News California looked back at another large fireworks-related explosion in California to get an idea of how the investigation in Yolo County may develop.

The Yolo County Sheriff’s Office reported Wednesday that the cause of the explosion remains unknown and that it’s still an active evacuation zone around the property. Footage
