Valentin Martinez, 42, was found fatally shot in the roadway in the Fontana area of San Bernardino County on June 6, 2025. Deputies from the sheriff’s Fontana station responded to a report of a man down in the street; the death was recorded the same day in Fontana.

Within days investigators identified two people believed to be responsible and learned they had fled across state lines. U.S. Marshals and Arizona authorities tracked them to the Golden Valley area near Kingman, and a coordinated Mohave County operation on June 9–10 resulted in both being taken into custody without incident. Mota was booked on a felony warrant for homicide; Rivera-Valles was booked on a felony warrant for accessory to homicide, and both faced extradition proceedings to California.

Officials have not publicly detailed a motive; arrest reports state investigators treated the case as a targeted homicide rather than a random act. If anyone knew Valentin Martinez or has information about what led to the shooting, please share what can help the investigation.
