September 18, 2017, Monday afternoon, at approximately 12:30 P.M., from the Rancho Cucamonga Police Deputies located a pick-up truck pulling a stolen trailer near the intersection of Arrow Route and Archibald Avenue in the vicinity of Rancho Cucamonga . The Deputies attempted a traffic stop on the vehicle; however, the driver, Alan Pacheco, failed to yield and a vehicle pursuit ensued. The vehicle included a passenger Domingo Guerrero.


Pacheco led Deputies through several streets in Rancho Cucamonga before entering the Eastbound Interstate-210. The pursuit continued from the eastbound I-210 to the westbound Interstate 10. While evading Deputies, Pacheco drove at speeds up to 80 mph, while towing the trailer and made erratic driving maneuvers endangering the public, Guerrero and the pursuing law enforcement.

As the pursuit continued westbound on the I-10, Rancho Cucamonga Police relinquished the primary pursuit responsibility to the California Highway Patrol (CHP). CHP maintained the primary agency of the pursuit until its culmination in the city of Pasadena.  


During the pursuit, Deputies received information from Guerrero's father that Pacheco was armed with a handgun.  It is believed that at some point during the pursuit, Pacheco threw the handgun from the vehicle. Officers did not recover a handgun on Pacheco, or inside the vehicle.  Officers searched for the weapon along the roadway but were unable to locate it.


Pacheco was arrested for possession of a stolen vehicle, felony evading, and kidnapping. He was transported back to Rancho Cucamonga and booked into the West Valley Detention Center. Pacheco's bail was set at $250,000.
