It is clear to me that this is the work of a serial satist prepudescent child killer. The absence of semen ,and or spermicidal lubricant from a condom indicate this was a foriegn object penetration. this being said, The primary motive for the crimes was not sex. Children that are abducted at this age are generaly the victem of a pedaphile who kills for the first time and are ussualy caught very quickly. This does not appear to be the case here. If we look at the so called ransom note you gain an insight into the mind of a serial killer: This serial killer seems to be preoccupied with violence towards children; he mentions violent acts toward Jon Bonet in the note repeatedly. Some one does'nt wake up one day and commit a crime like this; he has done this before. The olny other crime I am aware of that is similar to this is the abduction is and murder of jaqalyn dowiby of Midloathian Ilinois 1988. The cases are strikingly similar. The girls are the same age ,sex, and the M.O. is Identical.
