Seven Dead, Eight Charged, One Year of Unanswered Questions in Esparto

One year ago this week, seven workers at an illegal fireworks operation in rural Esparto didn’t come home. The explosions that killed them—Jesus Manaces Ramos on his first day of work, Joel Jeremias Melendez, who would never meet his second son, Angel Matthew Voller, an 18-year-old pitcher with his whole life ahead—were the result of what prosecutors now describe as a decade-long conspiracy that nobody stopped.

Eight people have been arrested. Five face seven counts of second-degree murder each. The criminal case marches forward through Yolo County courts. But for the families left behind, the real investigation is just beginning to reveal something more corrosive than any explosion: systemic failure.

Here’s the maddening part. County officials knew. They received tips in 2022 that a pyrotechnics business was operating illegally on the property. An email from a county building official said he’d“tread lightly”because sheriff’s deputies were reportedly involved. The Esparto fire chief confirmed fireworks were stored on-site and said he’d look into local regulations. Then nothing happened. No enforcement. No follow-up. The operation kept growing—from 13 shipping containers in 2015 to more than 50 by 2025. Over that decade, prosecutors say the business imported more than 11 million pounds of explosives.

A Yolo County Civil Grand Jury concluded in March that the county could have stopped it. Jury Foreperson Richard Zeiger said there was a point where officials“could have acted to close down that business operation and they did not.”Last week, county leadership rejected that conclusion entirely, blaming the state and federal authorities instead. Their defense? They were deceived. They took operators at their word that everything was legal.

Maria Melendez, widow of Joel Jeremias Melendez, called it a slap in the face.“It felt like they weren’t sorry and it felt like the way our loved ones died and what happened didn’t matter,”she said in a recent interview. She’s raising two young sons—one born months after her husband died—and still waiting for accountability.

Legislative proposals like Senate Bill 828 aim to close the communication gaps between state and local regulators. Yolo County says it’s reviewing its code enforcement policies. These reforms matter. But they can’t bring back the seven men who died because the system that was supposed to protect them failed—over and over again—to act.
