If he has been laicized, how can they control where he lives?

They can't "control" where he lives, but if he wanted to regain the favor of the Church, he would do what he was asked. Why would a pedophile want to regain favor with the Church? Since the man had chosen to become a priest, it's possible he actually saw the Church as something more than a cover for his sexual adventures.
