After an extensive six-year investigation, the Alberta RCMP Historical Homicide Unit has made an arrest in connection with the 2019 disappearance and homicide of Twyla Evans, a vulnerable woman whose body has not been recovered to date.
The victim, who was 39-years-old at the time of her disappearance, was reported missing in September of 2019. She was a resident of the City of Wetaskiwin, which is where investigators have confirmed she was last seen alive.
Despite exhaustive search efforts, her remains have not been located. Investigators, however, continued to pursue all available leads, and recent developments led to the arrest of Stan Cross, a 49-year-old male, who is now charged with 1st Degree Murder in Twyla’s death.
“This was a particularly heartbreaking case due to the significant vulnerabilities the victim faced in her daily life,” said Insp. John Spaans, Officer in Charge of the Wetaskiwin RCMP Detachment. “From the onset of the investigation our Wetaskiwin RCMP officers worked closely with the Serious Crimes Branch and are grateful to see the investigation has progressed to the point where charges have been laid.”
Stan Cross was arrested without incident on June 20, 2025, and was remanded into custody. The matter is now before the courts and no further details will be released to protect the integrity of the judicial process. His first appearance is scheduled for Tuesday, June 24, 2025, at the Court of Kings Bench in Wetaskiwin.
Insp. Breanne Brown with the Alberta RCMP Serious Crimes Branch, acknowledged the challenges involved in the long-running case and expressed gratitude for the public’s support throughout the investigation.
“Our Alberta RCMP Historical Homicide Unit is a team of dedicated and meticulous investigators who are working for those who can no longer speak for themselves. Our team has been able to bring Stan Cross to justice for his actions against Twyla Evans and provide some answers to her family and friends. The Alberta RCMP does not stop investigating in these circumstances and our team continues to work to bring Twyla home. I can assure you that our investigators pour their hearts into these investigations and are committed to providing answers to victim’s families regardless of how much time has passed.”
The Alberta RCMP continues to work closely with Crown prosecutors as the case proceeds through the justice system.
