I'm just curious if there is a precedence for a serial criminal to target victims on given days as some here are suggesting. It seems that these types of crimes would depend more on his "luck" finding an opportunity to snatch a victim. Granted, I don't live in a college town, but I know I would be hard pressed to find someone in the vulnerable situation as Hannah or Morgan on any given night, much less on a specific calendar day.
I know that there has been debates here as to his IQ, which, mixed with this "numerology" of sorts, begs the question: Would a purposeful pattern of abductions on specific dates indicate a higher IQ, or a lower one?
