Rescue crews were searching on Thursday for seven people still missing days after an explosion at a fireworks warehouse in Northern California shook a tiny farming community and forced the cancellation of nearby July Fourth celebrations.

In the first moments after explosions at a fireworks warehouse in Esparto rocked the community, a man who lived nearby sprang into action towards falling flames and live fireworks, just hoping he could help.

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.
