Sometimes when a child is missing they may be in significant danger and ODHS may need to locate them to assess and support their safety. As ODHS works to do everything it can to find these missing children and assess their safety, media alerts will be issued in some circumstances when it is determined necessary. Sometimes, in these situations, a child may go missing repeatedly, resulting in more than one media alert for the same child.
