A faster, more-efficient Amber Alert system has been tested in Missouri. And the State Highway Patrol says it works. The new system relies on radios in every station in the state instead of a system that had one station get the message and then distribute it to smaller stations in an area. Patrol Communications Director Jim Biggerstaff says the system is coded so the alerts can be issued regionally or statewide. The Amber Alert is used to alert the public when a child has been kidnapped. It’s also tied into the federal Emergency Alert System to alert the public about disasters or approaching disasters.
