Among those indicted are Yolo County Sheriff's Lt. Samuel Machado and his wife Tammy, who was a civilian employee for the sheriff.

Machado is facing seven counts of murder, records show. 

Also arrested were Craig Cutright, who owned Blackstar Fireworks, which kept fireworks at the facility, and Kenneth Chee, owner of Devastating Pyrotechnics, whose illegal fireworks were stored at the site. 

He was arrested in Florida at Walt Disney World. Law enforcement officials shared his booking photo. Chee is charged with seven counts of murder. 

Jack Lee, longtime Devastating Pyrotechnics operations manager, and Gary Chan Junior, whose name is associated with the company's federal license, were both arrested. 

One of Cutright's employees, Ronald Botelho III, was arrested in December for reckless possession of explosives and now faces 13 additional charges. 

The blast burned dozens of acres and damaged nearby homes. 

The seven victims killed in the July explosion were identified as:

  • Carolos Rodriguez Mora, 43, of San Andreas
  • Neil Li, 41, of San Francisco
  • Angel Voller, 18, of Stockton
  • Christopher Bocog, 45, of San Francisco
  • Jesus Ramos, of San Pablo
  • Jhony Ramos, 22, of San Pablo
  • Joel Melendez, 28, of Sacramento
