After finding more info on this character thanks to Wyld Rose. Number 7 on the link seems to go with the story i was told. Supposly this happened while he was a teenager. Since it has been over ten years, he does not have to register. The cops went over there last night. Hopefully I will feel safer when the detective handling this case calls me back to verify the above statments.
That is a good idea Redsnake. Thank you Workoutgirl for more info on the one down street.
As i was typing this the detective called back and said, "Mo. laws are different than IL. This happened back in 1988 and he has done his part registering as a sex offender. His case was over in 1996. The detective even said That guy called state police when he moved to IL. and asked if he has to register in IL. The detective verified with the state police to see if this was true.
With that being said, i do feel better knowing the facts. Still my kids NEVER go outside without me or their dad up their butts at all time.
