Query: Justice Denied

I went to school with these two girls. They were in my class!! It's amazing to know that this case was never solved, especially in this day of DNA. I was disheartened by two things. One, most of the names were changed. If the real names were put in the book, I might have had more of an idea who did it. Because I was pretty much in the same circles as these girls. Number two, the last 3/4 of the book was just letters that Detective Horak wrote to people asking for help. It became quite redundant. I'm trying to find the next book he wrote on this matter called "Truth and Justice". I can't find it anywhere!! Help
