The suspects, 30-year-old Marissa Navarro and 31-year-old Johnny Arroyo, were arrested Saturday after authorities linked them both as registered owners of a car connected with stealing gasoline from a nearby U-Haul truck.
Also inside the car, deputies recovered over 50 pieces of mail from residents in Chino Hills, Chino, Temecula, Murrieta, Corona, and Eastvale.
Navarro and Arroyo were arrested and booked into the West Valley Detention Center on several charges including conspiracy to commit a crime.
Authorities are also working to notify all mail theft victims in connection with this case.
