On October 21, 2017, Fillmore Patrol Deputies conducted a traffic stop on a vehicle driven by Jose Castillo for vehicle code violations.  During the traffic stop, deputies discovered two operational 'zip guns', including one that was loaded.  A 'zip gun' in a home-made firearm crudely constructed with miscellaneous parts.  These types of firearms are extremely dangerous due to their lack of safety mechanisms and standard firearm parts such as a trigger.  Zip guns can also be easily concealed or smuggled into restricted areas. A search of the vehicle also yielded methamphetamine and an unregistered shotgun.   


Jose Castillo and his passenger, Gabriel Pavich, were arrested for narcotic related and illegal firearm possession charges.  Pavich is a convicted felon and prohibited from possessing firearms. Castillo is being held in Ventura County Jail in lieu of $50,000 bail and Pavich was released on a bond.  Prior to Pavich's release, detectives seized an illegal rifle from Pavich's home in the City of Fillmore.


On the morning of October 28, 2017, members of the Sheriff's Gang Unit and the Camarillo Special Enforcement Detail executed a search warrant at Castillo's residences in the City of Oxnard.  An illegal AR-15 assault rifle, two illegal gun silencers, and evidence of illegal firearm manufacturing were located and seized.       


Investigators believe that Castillo and Pavich may have manufactured or sold other illegal and dangerous firearms.  Anyone with further information regarding this investigation or any gang and illegal firearm information is encouraged to contact Detective Erik Hernandez at 805-654-2856.
