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.

An investigation is ongoing after an explosion on Tuesday at a fireworks warehouse facility in Esparto as families are demanding answers and closure.

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.
