I thought we had someone on here who worked in the prisons, if not that one, and said that there was no way he was out and about, as a Level-3 sex offenders. I think it is kind of doubtful that he was given enough freedom to be able to commit murders, even if he was allowed to do something like pick up trash in a group setting.
I think I would be much more comfortable with stating that he could not have possibly committed any crimes during period x through period y if a guard from the prison he was in stated that at no time in those 8 years was he allowed outside the prison. I have never heard that. So, I guess I would like to know what prison is was at and was he in the same prison the whole time and was he ever at all allowed outside for any reason.
