Juveniles of all backgrounds are reported missing for a number of reasons, according to the MPD. Usually, it’s because they didn’t check in at home, work or school for voluntary reasons. More concerning cases tend to revolve around conflicts in the home. When younger children are reported missing, for instance, they could have been taken by a family member during a custody battle. Teenagers are more likely to be running away from physical or sexual abuse or a parent who’s using drugs.
