Canadian Man Jailed After Years-Long Tormenting Of Family Escalated To A Triple Murder
Dustin Duthie was hard to get along with, but nobody expected him to snap the way he did.
A Calgary, Canada man is serving life behind bars after he committed a brutal triple murder in 2018.
“I hate Dustin. I don’t classify Dustin [as] family anymore,” said Adam Pennylegion, Dustin’s stepbrother.
Pennylegion grew up alongside Dustin Duthie in a blended family consisting of his father, his stepmother (Dustin’s mom), as well as full and half-siblings. Pennylegion always thought Dustin was the smart one, but there were early signs that Dustin had a temper and was quick to get angry over small things.
One night as the kids played video games together, Pennylegion snooped through Dustin’s things and found his sketchbook. In typical little brother fashion, Pennylegion teased his older stepbrother about the drawings.
Dustin immediately grew angry, pulled a lighter from his pocket, and threw it hard enough to cut Pennylegion’s eyelid open. The siblings opted to keep the incident quiet and not tell their parents.
After that, Dustin began using his anger to manipulate the family. They all walked on eggshells around him in an attempt to avoid setting him off.
Pennylegion remembered a time when Dustin was frustrated with a cell phone and demanded his mother get him a new one. When she said no, he began yelling and calling her names before throwing his phone across the room. His mother quickly relented and said she’d buy him a new one. She tried to send the young man to therapy, but he would not agree to go.
As the children got older, Pennylegion realized Dustin was capable of far more than just outbursts. He appeared to have a criminal streak as well.
Dustin began rifling through unlocked cars to see what he could take, but one night the behavior escalated when he and a group of friends found a set of golf clubs in a vehicle. One of the friends then used a golf club to break a window at a school. They raided the vending machines, taking all the food back to Dustin’s home.
Dustin regularly got physically violent with his brothers and stepfather, leading him to be thrown out of the family home on more than one occasion. Still, nobody pressed charges against him.
Meanwhile, Dustin had begun training as a boxer and using steroids. The steroids brought his simmering rage even closer to the surface. Dustin grew stronger as he worked out nine times a week. Pennylegion assumed his brother would eventually meet his match in a bar fight, hoping then that he would calm down.
Instead, the violence only escalated.
On July 31, 2018, Pennylegion had plans to join his father for lunch, but his father wasn’t answering his calls to confirm their meeting. Finally, a strange number called, and it was an officer on the other line asking if he could come to Pennylegion’s home to discuss an important matter.
Get all the details on what happened that day as well as how Pennylegion helped put his stepbrother behind bars on Evil Lives Here: “I Found His Confession” on Aug. 7 at 11/10c. Episodes are also available to stream on discovery+.
