Hi, park enthusiasts. I'm your host, Dylia Diambra. And despite the fact that the case I'm going to tell you about today is nearly 40 years old, it still needs to be solved. There is an unknown predator who has gotten away with a heinous crime and who needs to be brought to justice. Or if they're no longer alive, at least give one Canadian family the answer to a question they've spent so many decades asking, who killed Margaret McWilliam?

The crime took place in the summer of 1987 in Toronto's Warden Woods Park, an urban green space that's situated on the eastern side of the city.

According to the city's website, the landscape includes a body of water known as Massey Creek

and a winding trail that cuts through the park providing visitors with a nature oasis in

what is otherwise a massive metropolitan area.

If any of you listening are city dwellers or from Toronto, then you probably can picture

what I'm describing.

Warden Woods, like a lot of city green spaces, is a patch of thick forest right in the

middle of intersecting neighborhoods and commercial roads.

If you're in a car, you can get there very easily.

If you're walking, biking, or even taking public transportation,

you're also going to be able to find your way in and out without any problems.

I mean, there's even a subway station about five minutes away from the park's northern entrance.

In August 1987, a young woman using the space to exercise found out in the worst way possible that someone

inside with violent intentions was watching her.

And planning a crime so horrific, it remains one of the most notorious cold cases in Toronto

Police Services history.

But my hope is that with the proper exposure and advances in forensic science, it won't stay that way forever.

This is Park Predators.
