The state's CLEAR, or Coordinated Law Enforcement Adult Rescue, Alert program was created in 2019 to help law enforcement locate missing, kidnapped or abducted adults or adults in immediate danger of injury or death, as well as find potential suspects. It serves to close the gap between missing children who qualify for Amber Alerts and senior citizens who are covered by Silver Alerts. The name also honors victims of violence: Cayley Mandadi, D'Lisa Kelley, Erin Castro, Ashanti Billie and the Rest.
