Cold case that puzzled Toronto-area police for nearly half a century cracked. Here's how they did it

For nearly 45 years, the identity of the human remains found along a rural road north of Toronto remained a mystery. It was on July 16, 1980, when a Markham, Ont. resident made the discovery near a wooded area on Eleventh Concession, between 14th and Steeles avenues. Unbeknownst to them, the remains belonged to William Joseph Pennell, a convict who had escaped a Kingston prison a month earlier.
