AUSTIN, Tex. - The Hailey Owens story may have you wondering how to keep watch on your children. There's a way to do it, using mobile phones and GPS technology.
A program called Amber Alert GPS lets you track your children, and warn them of potential trouble.
Russell Thornton founded Amber Alert GPS in Utah. After losing his three-year-old son for 45 minutes, he had a stroke of genius - to keep track of them with technology.
"GPS is used in cars," Thornton says. "It's used to track valuable assets, and there is nothing more important than your kids. So why not a miniature GPS that you can use to find and locate your kids?"
You slip the small device in a backpack or pocket, then track your child from a home computer or on an app. Green shows where they are now; red is where they've been.
"It has a single button. We call it an SOS button," said Thornton. "The child can press and hold that and it will call a designated single number."
Amber Alert GPS also has a predator function. "We tie into the national registry of sex offenders," Thornton explained. "If your child goes within 500 feet of the address of a registered sex offender, we give you what 's called a predator alert."
