(07/16/10) GREENWICH - LoJack will be helping families in Greenwich keep track of their loved ones with autism and Alzheimer's disease.

The Greenwich Police Department and the car tracking company have started a program to help families with members with mental disabilities find their loved ones should they go missing. The program is called Project Lifesaver and police say it can find a missing person within 30 minutes of activation.

The tracking device itself can be worn as a bracelet or sewn into the person's clothing. Should they go missing, police can use a handheld antenna that picks up the signal from the tracker.

Families with autistic children say the tracking system will give them peace of mind.
