At the request of Olathe PD, we sent out a Notify JoCo to an area in Olathe in reference to a missing 12-year-old juvenile. Approximately 1,736 citizens confirmed receipt of the message, with one of them being an employee of the Sports Shack and Brew Pub restaurant. Shortly after receiving the message, the juvenile walked in to the establishment. The employee recognized them due to the broadcast and notified law enforcement. We were able to make contact with the juvenile and return them home.
