There are many scenarios including exploitation and abuse.  We have many examples as well as stories published in the media that refer to this on our press room page.  One of the most well known cases refers to the case of Gary Leon Ridgeway (The Green River Killer) who confessed to murdering 48 teenage girls and women over two decades. According to an Associated Press 2004 report, he was quoted as saying, "I picked them as victims because they were easy to pick up without being noticed. I knew they would not be reported missing right away and might never be reported missing. I picked them because I thought I could kill as many as I wanted without getting caught." Several of Ridgeway's victims remain unidentified Jane Does to this day. These women were someone's daughter, mother, sister or friend.
