On May 3rd 2018, detectives from the Ventura County Sheriff’s Interagency Pharmaceutical Crimes Unit (PCU) assisted by the Ventura County Combined Agency Team (VCAT) and the Oxnard Police Department concluded a one month narcotic investigation into Joseph Keifer, Estevan Gutierrez and Armando Silvestre, who were involved in the sales of suspected Alprazolam (Xanax) and marijuana to residents of Ventura County.
