Ralph Daugherty is a computer programmer who was drawn to the Chandra Levy case based on coverage of the critical clues to her disappearance found on Chandra's computer. He has posted over 7,000 comments as rd on Chandra boards on the Internet and has set up his own board dedicated to Chandra Levy, Laci Peterson, and missing women at www.justiceforchandra.com. He has now pulled together the reported facts with his analysis and questions, honed by discussions with hundreds of other posters since Chandra's disappearance. This complex mystery is a compelling story, and "Murder On A Horse Trail" tries to do justice to that story.
