Victim killed by man dating his ex-girlfriend after he texted her, prosecution alleges
CBC
Two hours after Kalix Langenau texted his ex-girlfriend and arranged to meet up, her boyfriend stood two or three feet from the teen and used a shotgun to end his life, according to the theory presented by the prosecution on Day 1 of Hunter Van Mackelberg's trial.
Van Mackelberg was 19 years old when he was arrested and charged with second-degree murder in the death of Kalix Langenau, also 19.
On Monday, Langenau was described by witnesses — members of his family and friends — as someone who "loved the idea of love."
He hated drugs and being around anyone who was high. He had just enrolled at SAIT and dropped out because he was scared of the man now on trial for his murder.
The case involves two women, Madeline Kot and Sadie Boyle.
In 2017-18, Van Mackelberg was dating Boyle and Langenau dated Kot.
But that summer, the two pairs had split, and by the fall of 2018, Van Mackelberg was dating Kot while Langenau and Boyle were a couple.
The two men knew each other only through their girlfriends, according to witnesses.
Prosecutor Ron Simenik told Court of Queen's Bench Justice Glen Poelman that evidence will show Van Mackelberg's animus toward Langenau built through 2019 and into 2020.
Langenau's aunt testified that the windows of her nephew's car were shot out in the spring of 2019. Kelly Watkiss said Langenau "believed Hunter and Madeline did it."
Around that same time, Langenau told his aunt he'd heard "Hunter was going to shoot him."
"I'm in trouble," Langenau told his aunt. "Madeline and Hunter are out to get me."
That November, Watkiss helped her nephew get a job in B.C. after he said he "needed to get out of town."
Langenau came back to Calgary twice; once for Christmas 2019 and again in February 2020.
