Richmond Fire Suspect Charged with Three Counts of Murder

Martinez, California – The Contra Costa County District Attorney’s Office has filed murder charges against a Richmond man accused of setting a house fire that killed three family members and critically injured a fourth.

Sergio Ivan Rivera-Vega, 32, faces three counts of murder, with special enhancements tied to the deaths of an adult victim and two minor victims. A fourth victim, an adult woman, remains hospitalized with serious injuries; Rivera-Vega is charged separately with arson causing great bodily injury in connection with her injuries. All four victims are related to the suspect.

Richmond police and firefighters responded to a house fire on the 200 block of 15th Street on the evening of August 18th, at approximately 8:58 p.m. Detectives investigating the blaze identified Rivera-Vega as the person who intentionally set the fire. He was arrested and booked into the Martinez Detention Facility on August 19th, and the investigation continued in the days that followed.

The case was submitted to the District Attorney’s Office for review on August 21st, and charges were filed with Contra Costa Superior Court that same day. If convicted, the enhancements attached to the murder charges would carry a sentence of life without the possibility of parole.

“This fire is devastating for the entire family,” said District Attorney Diana Becton. “Knowing the suspect is related to the victims — including two children — makes this loss even harder to comprehend this senseless act. Our thoughts are with the family and the community affected by this tragedy. Just know that my office is committed to following the law and holding the suspect fully accountable.”

Rivera-Vega is scheduled to be arraigned on the charges on August 24th at 1:30 p.m. at the A.F. Bray Courts Building Annex in Martinez. He remains in custody in lieu of $2,500,000 bail.
