Law enforcement in Bay Area, across country bring attention to cold cases on 'National Missing Person Day'

It is National Missing Person Day, a time when officers in the U.S. will be highlighting unsolved cases in hopes of finding people's loved ones – or at the very least, bringing them closure.

Every year, 600,000 people go missing in the country. In fact, officials call it the "nation's silent mass disaster." Many of those children and adults are quickly found alive and well, but tens of thousands of others aren't and their cases go cold.

According to the National Missing and Unidentified Persons System – or NamUs – more than 22,700 are currently missing in this country. Nearly 1,700 of them are in Florida. That's the third-highest number of cases in the country behind California and Texas.

Today, she'd be 55 years old. Anyone with information is asked to call the Heartland Crime Stoppers: 1-800-226-8477.
