On 6/15/2010, Sex Crimes Detectives from the Major Crimes Bureau of the Ventura County Sheriff’s Department located and arrested two sex offenders for a violation of Section 290 of the California Penal Code, which requires persons convicted of specified sexual assault cases to register with the agency in whose jurisdiction they reside. The Ventura County Sheriff’s Department actively investigates and pursues individuals who violate the terms of their registration.

Sheriff’s detectives had received information that Frederic Koerner, a convicted sex offender, was allegedly in violation of the terms of his registration. Koerner had been registered as a transient with the Sheriff's Department with no residential address given; however, an investigation disclosed that he had established residence in a motor home in the rear of a church in Ventura and had been paying rent to the church for the last two years. Koerner was located and arrested in the parking lot of the church in Ventura.

Candido, also known as Rafael Zetino, was convicted of a sex crime in 1996 and deported to El Salvador in 2000. He subsequently returned to Ventura County and registered as a convicted sex offender with the Sheriff’s Department in 2002. In 2004, he discontinued registration and his whereabouts were unknown. An investigation by sheriff’s detectives determined that he had been working and residing in Oxnard. Candido was arrested at his residence while attempting to hide from detectives in a tree in the backyard.

Sheriff's Department detectives actively conduct investigations to verify the residential information provided by convicted sex registrants. Additionally, probation and/or parole searches are also conducted periodically. During a recent sweep, a parolee, William Inscoe, was arrested for an unrelated violation of his parole terms and booked into the Pre-Trial Detention Facility. A second registrant was found to be in violation of the registration process. An investigation into that violation(s) is continuing.
