BTK????
Oh yeah, you don't remember? The serial-killer who eluded capture for over 30 years, continued living in the same community all those years(Kansas). B=Bind, T=Torture, K=Kill, BTK. When exposed, he was working as Ordinance Control for the city/county, a law enforcement related profession.
Then he was very involved with his church and had worked his way to the top echelon in the church heirarchy. Woah! I may have to take back my remark about "knowing what's going on" in smaller churches. His church was a modest church in size.
