Seven people remain unaccounted for days after multiple explosions obliterated a fireworks facility Tuesday in the Esparto area of Yolo County, Cal Fire said. The explosions and fire that followed caused nearby evacuations and power outages.

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.

Walter Lucas has lived next to the fireworks facility and never imagined he’d witness a scene like this close to his home.
