On this episode of Global News podcast Crime Beat, crime reporter Nancy Hixt tells the story of a man who came face-to-face with pure evil.

Mark Mariani, 47, suffered from Crohn’s disease for more than half of his life.

On Oct. 1, 2010, Mark was given new hope, thanks to medical advancements. Doctors told him he might not need his colostomy bag anymore.

The next night, he headed to his favourite western bar to do some two-steppin’ and meet up with friends.

It was the following morning when Mark’s family received a call from police.

Mark was found dead in a Calgary strip mall parking lot — his keys, wallet and cell phone were found in a nearby alley.

Follow along as homicide detectives investigate the murder of Mark Mariani, and unravel the shocking reason why he was killed.
