Arizona has four types of emergency alerts that can be activated when other law enforcement methods have been exhausted.

On July 23, Arizona activated its recently-created Turquoise Alert for the first time. While the alert was subsequently canceled, the activation also led to some questions over what kinds of missing person cases qualify for Turquoise Alerts.

The Arizona Dept. of Public Safety held a news conference on the afternoon of July 24 after issuing its first-ever Turquoise Alert the day prior for a missing little girl out of Hawaii, last seen in Phoenix.
