Former Police Lieutenant Among Five Facing Murder Charges in Deadly Fireworks Explosion
A former California police officer is one of five individuals charged with murder following a catastrophic fireworks explosion that claimed the lives of seven warehouse workers. Samuel Machado, a former lieutenant with the Yolo County Sheriff's Office, allegedly stored one million pounds of fireworks on his property and exploited his law enforcement position to conceal the illegal operation from investigators, according to prosecutors.
Details of the Tragic Incident and Victims
The explosion occurred on July 1, 2025, at a warehouse in Esparto, California, storing fireworks manufactured by Blackstar Fireworks, Inc. and Devastating Pyrotechnics LLC. The blast was so powerful it could be felt up to 20 miles away, destroying a family farm and igniting a 78-acre grass fire. The victims, whose identities were confirmed by the Yolo County coroner's office, included:
- Christopher Goltiao Bocog, 45, and Neil Justin Li, 41, both from San Francisco
- Joel Jeremias Melendez, 28, of Sacramento
- Carlos Javier Rodriguez-Mora, 43, from San Andreas
- Jesus Manaces Ramos, 18, and Jhony Ernesto Ramos, 22, brothers from San Pablo
- Angel Mathew Voller, 18, from Stockton
Alleged Conspiracy and Official Negligence
Prosecutors describe a decadelong conspiracy that transformed Machado's property into a Northern California hub for importing illegal explosives on the black market. According to Deputy District Attorney Clara Nabity, the enterprise imported more than 11 million pounds of explosives and related materials, storing them in unapproved containers near residential areas and roadways.
An investigative report filed by the grand jury last month revealed troubling negligence by officials. In June 2022, the county Building Services Department received a tip about Machado's property being used for illegal fireworks storage but took no follow-up action. Emails show officials stating they would 'tread lightly' because the property was owned by 'deputies that we work with.'
'Inexplicably, no code enforcement occurred, even though all dangerous fireworks had been banned by ordinance throughout rural Yolo County since 2001,' the grand jury report stated. 'In the absence of official oversight and enforcement, unmitigated expansion of the fireworks businesses operating at the site in Esparto led directly to death and destruction.'
Additional Defendants and Charges
Alongside Machado, four others face murder charges: Devastating Pyrotechnics CEO Kenneth Chee, operations manager Jack Lee, business partner Gary Chan Jr., and Blackstar Fireworks' Douglas Tollefsen. Seven individuals total were arrested early Thursday morning, including Blackstar Fireworks owner Craig Cutright and Ronald Botelho III, who was already in custody on separate charges.
The 30-count indictment includes numerous additional charges such as maintaining an unsafe workplace, unlawfully starting a fire, insurance fraud, child endangerment, animal cruelty, tax fraud, and possession of illegal assault weapons. Machado's wife, Tammy, employed administratively at the Sheriff's Office during the explosion, faces separate charges for child and animal endangerment, tax fraud, and mortgage fraud.
Scale of the Investigation and Aftermath
Yolo County District Attorney Jeff Reisig described this as one of the largest investigations he has ever conducted, involving dozens of law enforcement agencies across California, the nation, and even beyond national borders. The illegal operation reportedly expanded dramatically from just 13 storage containers on Machado's property in 2015 to over 50 containers and a massive 5,000-square-foot warehouse by 2025.
The victims' families have filed a $35 million claim against the county and state fireworks regulators, accusing them of widespread negligence for allowing the illegal operation to continue unchecked. The case highlights significant failures in regulatory oversight and the deadly consequences when law enforcement officials allegedly participate in criminal enterprises.
