 Monette had mentioned the name of the motel where his wife and her lover were living, which would have made finding them a simple matter.The hitchhiker also presumably determined Monette's address from his car registration, since Monette later found his medallion lying on his desk with a note (presumably from the hitchhiker) thanking him for the ride.Monette (truthfully) denies having intentionally set the hitchhiker up to kill his wife but admits he is relieved about her death
