Hey, it's Nancy. Before we begin today, I just wanted to let you know that you can listen to Crime Beat early and ad-free on Amazon music included with Prime.

Lucy Tremel was living out a life of adventure and romance in the popular resort town of Banff, Alberta. Until her future was stolen,

early in the morning of May 17, 1990. She drove her cab to the iconic Banff Springs Hotel

and picked up two women and one man. Ten minutes later, she was found murdered.

Police believed a passenger tried to rob her.

She struggled and was able to flee the taxi, but her attacker chased her down and stabbed

her 17 times.

In Lucy's final moments, she made sure her killer left evidence behind. Because she fought back,

she injured her attacker who left a trail of blood as he fled the scene. Police had the

killer's DNA. The problem was identifying whose blood it was that marked the stolen cab.

And that turned out to be like finding a needle in a haystack.

Banff is an area popular with tourists.

And there were a lot of tourists from other countries there.

So any one of those tourists could have had an opportunity to commit a crime and then

return to their country of origin.

I'm Nancy Hicks, a senior crime reporter for Global News.

Today, on Crime Beat, I share the groundbreaking techniques

investigators used to track Lucy's killer. This is the conclusion of murder in the

mountains. In the fall of 1991, a young man from Ontario followed his heart west to Banff, Alberta.

My girlfriend was working at the top of the Sulphur Mountain Gondola,

and first or second day out there, after I got settled, I went out there to see her for lunch.

Dwayne Jung rode the gondola up the mountain in awe of the spectacular and breathtaking views of Banff.
