Ramos Sr., who traveled with family from Los Angeles after hearing of the explosions, said officials had not provided updates on their whereabouts. Syanna Ruiz, the 18-year-old girlfriend of Jesus Ramos, had also voiced frustration over the lack of information during a news conference the previous day.

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.

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.
