Introduction
The focus of this article is how top level Yolo County administrators, including the Office of the County Counsel, ignored illegal fireworks businesses on property owned by Sam and Tammy Machado in Esparto.
Based on a Public Records Act request, this author received a large collection of emails that document a series of negligent mistakes made by county employees. These emails are limited in number because of legal privilege and an ongoing investigation into the explosion and fatalities. However, of the numerous emails received by this author, not one county employee stated in writing to a representative of Sam Machado, or among themselves, that Yolo County passed an ordinance in 2001 banning the possession, storing or selling of dangerous fireworks – even when county employees knew there were fireworks stored at the site. More important, if the county had taken code enforcement action, the explosion, fire and fatalities would have never occurred.
The lack of action for code enforcement in regard to the Machado property also includes the Chief of the Esparto Fire Protection District, as documented in the March 26, 2026, report entitled “Yolo County Civil Grand Jury 2025-2026 Esparto Fireworks Explosion: Officials Knew, None Acted.”
As stated in the Grand Jury report:
“In the evening of July 1, 2025, massive explosions obliterated a family farm located at the northwest corner of County Roads 23 and 86A in Esparto. This incident, commonly known as the Esparto Fireworks Explosion, claimed the lives of seven workers….The explosion leveled the site and ignited what was named the Oakdale Fire, which expanded to 78 acres including nearby properties….Seven employees of a company called Devastating Pyrotechnics were killed instantly….”
The county’s lack of action ultimately led to the tragic deaths of:
Name Age
Jesus Manaces Ramos – 18
Angel Mathew Voller – 18
Jhony Ernesto Ramos – 22
Joel “Junior” Jeremias Melendez – 28
Neil Justin Li – 41
Carlos Javier Rodriguez-Mora – 43
Christopher Goltiao Bocog – 45
The victims included three brothers – Jesus Ramos, Jhony Ramos, and their eldest stepbrother Joel Melendez.
