Missouri Missing Children

Missouri's missing child system is run by the Missouri State Highway Patrol, which keeps the Missouri Missing Persons Clearinghouse and administers the AMBER Alert plan, with reports taken by the city police or the county sheriff and cases posted nationally by the National Center for Missing and Exploited Children. There is no waiting period.

Missouri tightened its rules after the 2014 abduction of Hailey Owens in Springfield, when hours passed before an alert went out. Hailey's Law requires Missouri agencies to move the AMBER Alert request through faster and gave the Patrol a direct role in activating it.

The Missouri State Highway Patrol activates an AMBER Alert at the request of the investigating agency when a child under 18 has been abducted, is believed to be in danger of serious harm or death, and there is enough information about the child, the abductor or a vehicle to help the public. The alert reaches radio and television through the Emergency Alert System, phones through the wireless emergency alert system, and the Missouri Department of Transportation highway signs, and the Patrol shares it with the eight bordering states. Cases that fall short of the abduction standard can be issued as an Endangered Person Advisory, which goes to media and online without the phone alert.

The Missouri Missing Persons Clearinghouse in the Highway Patrol keeps the statewide file of missing children and adults, posts photos and case details online, coordinates with the National Center and NamUs, and helps local agencies with cases that cross county or state lines. Start with the city police or the county sheriff, get the case number, and check that the child is in the National Crime Information Center, which every police agency in the country can see. In Missouri, the next call is to the National Center for Missing and Exploited Children. St. Louis and Kansas City police have their own missing persons units, and the Patrol takes reports directly on the highways and in rural areas.

Missouri's Endangered Person Advisory also covers missing seniors and adults with dementia or disabilities, its Silver Alert covers seniors believed to be driving, and its Blue Alert covers suspects who have injured or killed a law enforcement officer. The file itself stays with the investigating agency. Under the Missouri Sunshine Law, the incident report is public while the investigative file can be withheld until the investigation becomes inactive, and juvenile records are confidential. In Missouri, older cases reach NamUs only when the investigating agency or the family submits them and the agency approves publication, so the public NamUs search shows a share of the state's open cases, not all of them.
