WAUWATOSA, Wis. (CBS 58) -- Wauwatosa Police are learning how to use Project Lifesaver, a program that helps bring lost loved ones home. 

Project Lifesaver is already available in more than 30 Wisconsin counties. Earlier this year, Ozaukee County officials showed CBS 58 how it was used. 

Project Lifesaver places a transmitter on a person with autism, dementia, or anyone with a tendency to wander. The transmitter looks like a watch. 

If the person wanders, law enforcement is able to track the person down with a receiver. More than 3,000 missing people have been found with the help of Project Lifesaver.
