Candles were lit on Thursday evening for the vigil of Rebecca Autumn Mathieson (Wilson), who died late last month after being seriously injured in an assault. Rebecca’s younger sister, Katie, said that her older sister was “funny in terms of the cards she was dealt” in life. “Becky was just like a light in the world, I think she was funny in a way that is unmatchable,” said Katie. “Funny in a way that me and my other sister were talking about, there’s just no one that’s like Becky or thinks the way that she does.” Katie described her older sister as a “ride or die person,” who was a devoted Christian that loved reading the bible, talking to people, and going for long walks. “We have so many kids in our family, so it would be us and a bunch of strollers with Tim Horton’s coffees and just processing life together through walking. That’s something I feel like I’m going to miss a lot.” Rebecca also had quite the sense of humour, according to Katie. “[She was] just always making jokes because the world is so dark, and I think Becky has had a really tough life in terms of just not being really set up to succeed in a lot of ways,” she said. “She grew up homeschooled for a period, then went straight into high school pretty much in Regina. Just as an Indigenous woman, she’s just a lot of times, not really believed or not given the benefit of the doubt.” The ongoing investigation On Sept. 3rd, the Regina Police Service (RPS) announced that Mathieson, 37, had died from the injuries she sustained during an assault earlier in the month. On Aug. 14, police received a call about an injured person found in the west alley on the 1400 block of Wascana Street at around 4 a.m. The aggravated assault investigation was ruled as a homicide investigation after Mathieson died on Aug. 30. “She didn’t just die, she didn’t just pass away from some sickness, or some freak accident - she was murdered. So, there’s no resolution to that,” said Katie. “We’re still every day, moving through that feeling, that uncertainty, and also trusting that so that Becky will help guide us in some way to the answers.” Katie says she would like there to be “more transparency” and “more active involvement” from RPS. “I know it’s very complicated with the Regina police right now because it is an active investigation, so there are certain things that I have my opinions about and wish I knew more about,” she said. “But at the end of the day, I want justice for Becky, and I want justice for women like Becky.” In a statement to CTV News, RPS said its major crimes unit is “working hard to determine the circumstances that led to the death of the victim.” This was the fifth homicide incident of 2026. RPS asks anyone with information that could assist investigators to contact police or Regina Crime Stoppers. A GoFundMe has been created to fund an independent investigation of Mathieson’s death, with leftover funds going towards supporting the families of missing and murder Indigenous people.
