A Silver Alert is activated when a person with specific cognitive or developmental disabilities, as defined by statute, or a person the age of 65 or older goes missing. Prior to June 2018, this only applied to persons over 65. 

The purpose of the Silver Alert program is to establish a notification system that provides immediate information to the public through issuing and coordinating alerts using various resources following a subject "gone missing" when specific criteria has been met. 

The goal of the Silver Alert is to locate the missing person, when Silver Alert criteria is met, through efficient information dissemination and communication that results in safe and expedient recovery.
