Michael Moreno was 43 and a resident of Antioch, California when he was fatally shot on May 18, 2020. Moreno, a military veteran who owned the California Combat Academy gym in Pittsburg, was shot in his apartment at about 8:30 a.m. after an argument with his roommate at a home in the 1900 block of Iron Peak Court. Officers who responded found Moreno already deceased; the Contra Costa County coroner later identified him.

The roommate, 41-year-old Marc Siegel, was arrested and charged with one count of murder with a gun enhancement. He was held at the county jail in Martinez on $2 million bail. Police described the incident as an argument between roommates that escalated into a shooting; the precise nature of their dispute has not been disclosed. The district attorney’s office filed charges and legal proceedings were pending.

Did anyone in the Antioch or Pittsburg community know Moreno or have information about his relationship with the roommate that could help the case?
