Cop Charged with Murder After a MILLION Pounds of Fireworks Explodes

What prosecutors are describing as a deadly, yearslong abuse of power in Northern California has now exploded into one of the most disturbing public corruption cases in the state in recent memory.

A former Yolo County sheriff’s lieutenant is among five people charged with murder after authorities say a massive illegal fireworks operation tied to law enforcement protection ended in a catastrophic explosion that killed seven workers and devastated an entire community.

According to prosecutors, former sheriff’s lieutenant Samuel Machado allowed his property in Esparto, California, to become a major storage and distribution hub for illegal explosives. Investigators say the site held roughly one million pounds of fireworks at the time of the blast and that Machado used his badge and insider status to help keep the operation out of investigators’ sights.

The deadly explosion tore through a warehouse on July 1, 2025, sending a fireball into the sky, shaking homes as far as 20 miles away, destroying a family farm, and sparking a 78-acre grass fire. Seven workers were killed in the blast.

The victims were identified as Christopher Goltiao Bocog, 45, and Neil Justin Li, 41, both of San Francisco; Joel Jeremias Melendez, 28, of Sacramento; Carlos Javier Rodriguez-Mora, 43, of San Andreas; brothers Jesus Manaces Ramos, 18, and Jhony Ernesto Ramos, 22, of San Pablo; and Angel Mathew Voller, 18, of Stockton.

Their deaths have now become the center of a sweeping criminal case that prosecutors say exposes not just a dangerous illegal business, but a stunning breakdown in public accountability.

At the heart of the case are two companies, Blackstar Fireworks, Inc. and Devastating Pyrotechnics LLC, which prosecutors say were manufacturing and storing explosives so dangerous they allegedly did not even qualify as legal fireworks. A 30-count indictment returned by the Yolo County District Attorney’s Office accuses the defendants of operating a black-market enterprise that expanded for years with little meaningful interference.

Deputy District Attorney Clara Nabity said the alleged conspiracy turned Machado’s property into the Northern California base of an illegal operation that imported explosives on the black market. Prosecutors say the enterprise brought in more than 11 million pounds of explosives and related materials, storing them in unsafe conditions near homes, roadways, and even a family swimming pool.

What makes the allegations especially explosive is the claim that officials were warned long before the fatal blast.

An official in the county’s Building Services Department reportedly received a tip in June 2022 that Machado’s property was being used to store dangerous materials. But according to investigators, nothing meaningful happened after that. Emails cited in the case allegedly show local officials saying they would “tread lightly” because the land belonged to “deputies that we work with.”

That detail is likely to fuel even more outrage, especially as the case raises questions about whether law enforcement connections helped shield a deadly operation while workers and nearby families were put at risk.

A grand jury report filed last month was blunt in its conclusion, saying that no code enforcement action was taken even though dangerous fireworks had been banned throughout rural Yolo County since 2001. The report said the lack of oversight allowed the operation to grow unchecked until it led directly to “death and destruction.”

Prosecutors say the business expanded dramatically over the years. In 2015, Devastating Pyrotechnics allegedly had just 13 storage containers on Machado’s property. By 2025, authorities say, the site had ballooned into a sprawling compound with more than 50 containers and a 5,000-square-foot warehouse.

Among those charged with murder are Machado, Devastating Pyrotechnics CEO Kenneth Chee, operations manager Jack Lee, business partner Gary Chan Jr., and Douglas Tollefsen of Blackstar Fireworks. Blackstar owner Craig Cutright was also charged, along with Ronald Botelho III, a Blackstar employee who had already been in custody on separate charges before being added to the case.

District Attorney Jeff Reisig said the investigation is one of the biggest his office has ever handled. He said it has involved dozens, and possibly hundreds, of law enforcement agencies across California and beyond, stretching across state lines and even beyond U.S. borders.

The case does not stop at murder charges. Prosecutors have also stacked on a long list of additional allegations, including maintaining an unsafe workplace, unlawfully starting a fire, insurance fraud, child endangerment, animal cruelty, tax fraud, mortgage fraud, and possession of illegal assault weapons.

Machado’s wife, Tammy, who worked in an administrative role at the sheriff’s office at the time of the explosion, has also been placed on leave. She is separately charged with child and animal endangerment related to the alleged storage of illegal fireworks on the property, along with tax and mortgage fraud accusations.

For the families of the victims, the criminal charges are only part of the story. They have also filed a $35 million claim against Yolo County and state fireworks regulators, accusing officials of widespread negligence and of allowing a clearly dangerous operation to continue despite warning signs.

That claim could become one of the most politically damaging parts of the fallout. This is no longer just a story about illegal fireworks. It is a story about power, protection, and what happens when institutions appear to go easy on insiders while ordinary workers pay the price with their lives.

In a state that already faces growing distrust over regulatory failures and unequal accountability, the allegations out of Esparto land with special force. Prosecutors are painting a picture of a system where red flags were ignored, enforcement was softened, and a politically connected figure allegedly operated above the rules until the consequences became impossible to hide.

Now, with seven workers dead and a community still scarred by the blast, the question hanging over this case is as explosive as the charges themselves: how many chances did authorities have to stop this before it turned into a mass-casualty disaster?
