Thousands of people were involved in the search for Adrien McNaughton in the days and weeks following his disappearance in 1972.

Lakes were searched. Dogs, the military and even psychics weighed in. With such an intensive search, you'd think that something would be found.

"By our standards the child is dead. My first impression is the child was abducted, but not by a human being. Take that for what it is worth..."
