A wanted poster should contain a picture of the alleged criminal or a composite sketch if no images are available, according to Laws.com. Wanted posters are distributed by law enforcement officials to assist in tracking down fugitives and individuals suspected of crimes.
Other elements of a wanted poster include basic personal information such as the alleged criminal's name, aliases, and birth date. The individual's physical description, along with scars, birth marks and tattoos can assist members of the public in making a positive identification. Details of the crime are often included on the poster as well, states Laws.com.
The FBI has begun a new initiative where details about wanted criminals are displayed on electronic billboards. This approach affords higher public visibility and the ability to frequently update information on the suspects, according to the FBI website.
