I've seen a few reference's to this "Trolley Rulle" but apparently the police are taking the youtube page seriously. I wonder if there is link in some way to Lanza pre-shooting. It wouldn't be totally out of the realm of possibility that the book has some kind of cult following. Perhaps the police found a copy of it in the Lanza home? Who knows... it's total speculation at this point. I look forward to seeing how this plays out. I've tried to find any real information on the author and came up with nothing other then a lawyer in Quitman, GA
