Considering that the JW's knock on every door in the USA and Canada at least once every 4-6 months it's hard to believe they have never found him.
Of course if a JW had actually found McLean they would have reported it to the elders, who would have reported it to the branch office, who would have reported it to the Watchtower legal department, who would have reported it to ... well no one, as per the instructions of the Governing Body of Jehovah's Witnesses because there are no mandatory reporting laws for child sex offenders on the US Marshall's Most Wanted List.
