LAKEPORT, Calif. – Police have arrested a Ukiah man for failing to be properly registered as a sex offender and violation of his probation terms.
Austin Dion Duncan, 25, was taken into custody on Monday, according to Lakeport Police Chief Brad Rasmussen.
Rasmussen said that on Monday afternoon Lakeport Police officers were contacted by a citizen who reported having problems with a subject staying off and on at a rental residence without authorization in the city of Lakeport.
The reporting party had reviewed the California Department of Justice Megan's Law Web site and learned the subject was a public disclosure sex offender, Rasmussen said.
Lakeport Police officers conducted a background and records check on the subject – identified as Duncan – who was registered as a transient sex offender in Ukiah, according to Rasmussen.
He said officers also learned that Duncan was on felony Post Release Community Supervision, or PRCS, with a search and seizure clause.
Due to the information they developed, Lakeport Police officers believed that Duncan also was maintaining residence in Lakeport on 16 Street. Rasmussen said the officers went to the residence to conduct a probation search and continue the investigation on Duncan's registration status.
Duncan was located in the residence and detained for further investigation. Rasmussen said the officers determined that Duncan had a regular pattern of staying at the Lakeport residence over the past two months.
Rasmussen said California law requires that Duncan be registered in both Ukiah and Lakeport. However, Duncan had not previously notified the Lakeport Police Department of his residence status.
Officers arrested Duncan on a felony charge of failing to be properly registered as a sex offender and a felony violation of PRCS. Rasmussen said Duncan was transported and booked into the Lake County Jail.
On Wednesday morning, the Lakeport Police Department learned that the Lake County District Attorney's Office had filed a felony complaint against Duncan, Rasmussen said.
Rasmussen said that complaint charges Duncan with failing to comply with California sex offender registration provisions, along with enhancements for having a prior serious or violent felony conviction, in this case, for lewd or lascivious acts.
The complaint also charges Duncan with having two prior prison terms, one out of Lake County Superior Court for a 2010 sex offense conviction and the second out of Mendocino County Superior Court for a 2015 failure to properly register as a sex offender conviction, Rasmussen said.
Rasmussen said Duncan currently remains in custody on a no bail hold.
