National Missing Children's Day, Wednesday (May 25), is a day to bring public awareness to the fact that tens of thousands of children go missing each year in the US.

In 2015, Colorado law enforcement had more than ten thousand reports of missing children. Most of those cases were solved in a few days while others took weeks.

What is surprising is that as of January, there were 220 active cases in Colorado of children who had been missing a year or longer.

The Colorado Bureau of Investigation (CBI) along with The Center for Missing and Exploited Children, asks that parents take the time to educate their children how to stay safe, including online.

Parents looking for help can use resources including 'Be Here for Kids' that will aid them in talking about safety in a way their children can understand.

As part of the Colorado Missing Children's Day, the CBI is hosting an event at the state capitol in Denver. The event will present an award to Duyen Vu, the student who won a statewide poster contest recognizing National Missing Children's Day.

Governor John Hickenlooper will also sign a proclamation designating the day as Colorado Missing Children's Day.
