Although I was on the Anderson Cooper 360 show last night (6/30/2008) my comments on the psychological make of the person who wrote the ‘diversion letter’ was never aired.
Two possibilities exit about when the alleged Zodiac ‘symbol’ was drawn on the mirror in the Fairfield Inn. Plan one was put in play after the offender, realizing that he was in trouble originally left the Fairfield Inn and then returned later with the Zodiac plan. This plan would have been risky as the offender would have had to leave then return providing ample opportunities to be witnessed. Plan two is probably the most plausible. After the death, the offender realizing that he was in trouble set in motion the Zodiac plan. Plan two has the offender ‘staging’ the crime scene immediately following Ms. Touma’s death; he then flees the scene for good.
After scanning the various news articles related to this case I can find no mention of the term ‘staged crime scene,’ which is exactly what police are dealing with in this case. Considering the offender staged the scene to make it look like the copycat work of the infamous serial killer “Zodiac’ then is it likely that he staged aspects of the body and/or evidence to thwart the police investigation. Hence, we now know the manner of death (homicide) but not the mechanism of death. What true crime book did the offender borrow from to mask the mechanism of death?
