One of the three men who were hospitalized Aug. 7 after a cigarette ignited paint fumes and caused an explosion in the van they were riding in by West Valley Medical Center in Caldwell has died, according to Idaho State Police reports.

ISP officials say 58-year-old Jose L. Gonzalez of Greenleaf died early Thursday. He had been hospitalized in Salt Lake City since the crash.

Investigators say the explosion occurred right after 30-year-old Roman Gonzalez, who was driving a grey GMC Savana van with two passengers inside and filled with paint and chemicals, lit a cigarette and then dropped it on the floor, according to Caldwell Fire and ISP reports.

The crew had just left a painting job in Caldwell before 6:30 p.m. and Gonzalez was driving the van westbound on West Logan Street when he dropped the lit cigarette, which ignited paint and chemical vapors and caused a fireball in the van, according to reports.

Roman Gonzalez and front seat passenger, 50-year-old Ramon Gonzalez, jumped out of the van while it was still in motion.

The backseat passenger, Jose Gonzalez, was not able to get out of the van before it crashed through a fence and came to a stop in the front yard of a nearby house, according to ISP reports.

All three people in the van were taken by ground ambulance to West Valley Medical Center in Caldwell. Driver Roman Gonzalez and Jose Gonzalez were later taken by air ambulance to Salt Lake City.

The van was a total loss.
