Only three of 46 people contacted by police Wednesday had not followed state sex offender registration laws or were violating probation terms, Santa Rosa police said.

Officers from several agencies joined Santa Rosa police during the all-day effort to make sure sex offenders registered in the city were complying with the law, Sgt. Terry Anderson said.

As of Wednesday, there were 320 registered sex offenders in Santa Rosa, Anderson said. Of those, 70 people are transient, which means they must check in with police each month.

Police visited 46 residences Wednesday and found 36 people were complying with the laws, Anderson said.

Of those arrested, Charles Ramsey, 52, of Santa Rosa was being held at the Sonoma County Jail without bail on suspicion of violating probation and failing to notify police when he moved, records show.

Joshua Conway, 27, of Santa Rosa also remained at the jail on suspicion of violating probation, jail staff said.

A third person was arrested for failing to meet the annual registration requirement but was unidentified because of state laws guiding the sex registry system, Anderson said.
