Emergency services: Silver Alerts.

Existing law authorizes a law enforcement agency to request the Department of the California Highway Patrol to activate a Silver Alert, as defined, if the agency receives a report of a missing person who is 65 years of age or older, developmentally disabled, or cognitively impaired, and certain conditions are met, including that all local resources have been utilized and the disappearance is unexplained or suspicious. Upon concurrence by the Department of the California Highway Patrol that the precedent conditions have been met, existing law requires the patrol to issue the alert, which may take the form of a be-on-the-lookout alert, an Emergency Digital Information Service message, or an electronic flyer, within a specified geographical area. This bill would authorize the Silver Alert to be made by changeable message sign if a law enforcement agency determines that a vehicle may be involved in the missing person incident and specific vehicle identification data is available for public dissemination.
