The Explosion
At about 8:30 p.m. on July 4, 2026, a vehicle fire on the 5600 block of D Street in Chino, California, ignited a large quantity of fireworks, producing a powerful blast that set a second car ablaze. Four people were taken to local hospitals: a woman in her twenties who later died, two adults with severe injuries, and a juvenile who was released after evaluation. Police closed nearby streets while investigators secured the area.

Derion Tradon James Jr., 28, of Hesperia, was detained at the scene and booked on suspicion of involuntary manslaughter (California Penal Code §192(b)). The victims include an unnamed woman in her twenties (deceased), two adult survivors, and a child. Two vehicles were engulfed, one suspect arrested, and multiple local streets remain closed pending clearance.
