 There's a difference between a child being reported missing and an adult being reported missing. As an adult, you have the right to go where you please and to not be found if you so wish. As a child, your parent or guardian has the right to determine where you go and what you do. So as a child, if you go missing and you're found by law enforcement, you will be detained so that that officer can ensure that you get back to where your safe place is. You can be brought back home by the officer or if you're running away for a reason, let's just say you're the victim of abuse, then that law enforcement officer can act on that information that you as a Jew will give them and can ensure another appropriate safe place for you. Whether someone is an adult or as a child and they're determined to be at risk, if they function at, let's say, the level of a six-year-old or something like that, or an elderly person who has some kind of memory issues, then there is a heightened response to that because there is more concern for their safety.
