Seven people remain "unaccounted for" in Yolo County's town of Esparto after several explosions at a fireworks warehouse resulted in a fire, officials said.

Among those waiting in anguish is Jhonny Ramos. His 18-year-old son Jesus and 22-year-old son Johnny are still missing. Speaking in Spanish, Ramos said there couldn’t be a more “cruel death” and believes their bodies may still be buried in the rubble.
