MOST WANTED
On February 21, 2004, the FBI began its Endangered Child Alert Program (ECAP) as a new proactive approach to identifying unknown individuals involved in the sexual abuse of children and the production of child pornography. A collaborative effort between the FBI and the National Center for Missing & Exploited Children, ECAP seeks national and international exposure of unknown adults (referred to as John/Jane Does) whose faces and/or distinguishing characteristics are visible in child pornography images.
