The parents of three brothers — 18-year-old Jesus Ramos, 22-year-old Johny Ramos and 28-year-old Junior Melendez — faced the danger head-on, desperate to find their sons after the fireworks facility they worked at exploded.

Human remains have been found at the warehouse filled with fireworks that exploded in Northern California this week, officials said.

Seven people remain unaccounted for after a massive fireworks warehouse explosion in Esparto, California. Officials say they’re moving towards recovery efforts as families still wait for answers about their loved ones.
