View missing persons on the U.S. Department of Justice website or NamUs.gov, as well as sites such as SomeoneIsMissing.com. The free National Missing and Unidentified Persons System allows you to look through its database as well as type in the name of the missing person to conduct a search.
Through the National Missing and Unidentified Persons System, there are three available databases for viewing missing, unidentified and unclaimed persons as of 2015. You can also create a case file by entering information regarding a missing person into the site's database that is automatically cross-matched between the databases. Federal law requires law enforcement agencies to investigate every reported missing child immediately as well as vulnerable adult cases. The Amber Alert is activated nationwide for every missing child under 18 years of age.
Each state has a missing persons website, including New York State Division of Criminal Justice Services. Each states' website layout is different and provides an abundance of information with links to click to view different missing persons categories.
You can list a missing person as well as view pictures and descriptions of missing people on SomeoneIsMissing.com, a nationwide website. It is most important to contact your local law enforcement agency if you are concerned about a missing person.
