On 12/15/15, officers from the Oxnard Police Department responded to a residence in the 1000 block of Offshore Street in the City of Oxnard regarding a death investigation.  When officers and EMS arrived, they found the person unresponsive.  The victim was pronounced dead at the scene.  Officers learned the decedent's name was Christopher Ariaz.  Evidence recovered at the scene indicated Ariaz possibly died from a heroin overdose.  An investigator from the Ventura County Narcotics Task Force responded to the scene.  Investigators identified a probable source of Ariaz' heroin as Oxnard resident Ryan Tepezano.

On April 27, 2016, narcotic detectives concluded their investigation into Ariaz' death with the presentation of the case to the Ventura County District Attorney's Office.  Tepezano was arrested at the Todd Road Jail Facility for manslaughter and sales of heroin with an enhancement of causing great bodily injury.
