The bill amends Chapter 42-28 of the General Laws, introducing a new section titled "PURPLE alert" aimed at enhancing the response to cases of missing adults who have serious physical, behavioral health, or neurological disabilities. The legislation establishes a framework for a voluntary partnership among law enforcement, media outlets, and relevant agencies to disseminate emergency alerts for missing adults whose conditions raise immediate safety concerns. The criteria for a "PURPLE alert citizen" include being 18 years or older, having a serious disability or condition, and posing a credible threat to their safety, as determined by law enforcement.

Additionally, the bill mandates the Division of State Police to develop protocols and procedures for implementing the PURPLE alert system, ensuring that these procedures are regularly updated in consultation with involved entities. The act emphasizes the importance of timely alerts in the critical first hours following a disappearance and requires law enforcement agencies to gather and relay descriptive information about the missing individual to facilitate the alert process. This act will take effect upon passage.
