The Santa Cruz County Sheriff's Office continues to maintain his case in their database, seeking any leads that may provide more insight into his whereabouts.

The Santa Cruz Search and Rescue (SAR) team has been actively involved in assisting with searches for missing persons like Ronald. SAR works in collaboration with the Santa Cruz County Sheriff’s Office and uses a variety of specialized teams to search for and potentially recover missing individuals. Volunteers from SAR contribute extensively, often conducting operations on foot, in vehicles, or with specialized equipment, including water and air searches. They work tirelessly in various conditions to help locate individuals who go missing in Santa Cruz County and surrounding areas, which has been a significant part of the community’s response to such incidents since 1972.

Ronald’s case is also listed on major missing person platforms like the California Department of Justice's missing person database and The Charley Project. According to reports, his disappearance is classified as suspicious, and there have been few significant developments since he was reported missing. Authorities urge anyone with information about Ronald Jacobson or other missing individuals to contact local law enforcement or the California Department of Justice's toll-free hotline, hoping for any tips that could lead to a resolution of his case.
