What is a purple alert?

A Purple Alert is a system designed to help law enforcement quickly disseminate information to the public about an abducted child. Unlike Amber Alerts, which are triggered by specific criteria involving the abduction of a child believed to be in immediate danger, Purple Alerts are typically used in cases involving vulnerable adults with cognitive impairments who have been abducted. They are not standardized nationwide; the criteria, activation process, and even the name itself (some states use different names) can vary significantly from state to state.

Here's what we know generally about Purple Alerts:

• Purpose: To rapidly mobilize the public and law enforcement resources to locate a missing vulnerable adult, often someone with dementia, Alzheimer's disease, autism spectrum disorder, or other cognitive impairments that put them at risk. The aim is to increase the chances of a safe and timely recovery.

• Triggering Criteria: The specific criteria for issuing a Purple Alert vary by state, but generally involve the abduction of a vulnerable adult, often with confirmed evidence of abduction and a high degree of risk. This differs from Silver Alerts, which are often used for missing adults at risk (e.g., due to dementia), but not necessarily abducted.

• Dissemination: Similar to Amber Alerts, information is spread through various channels, including radio broadcasts, TV news alerts, highway signs, social media, and other public notification systems. The alert typically includes a description of the missing person, their vehicle (if applicable), and any other relevant information.

• State-Specific Nature: The absence of a federal Purple Alert system means there's no uniform set of guidelines. Each state that has adopted a Purple Alert system has its own specific protocols. This can lead to inconsistencies in how and when alerts are issued.

In short, while the concept is similar across states – quickly alerting the public to a serious situation involving a missing vulnerable adult – the specifics of activating and disseminating a Purple Alert are largely determined at the state level. To know the exact criteria and procedures for a particular state, it's necessary to consult that state's law enforcement or emergency management agency.
