In a developing story, the Royal Canadian Mounted Police (RCMP) are actively searching for Diane Cooper, an 82-year-old woman who was reported missing after failing to return home to Calgary on April 7, 2026. Cooper was last seen on April 6, fueling up at a gas station in Stettler, Alberta, before her vehicle was captured on video surveillance in the Hoosier area at approximately 10:51 p.m.
Cooper was traveling with her family’s Dalmatian, Halo, and is believed to be driving a grey Toyota C-HR XLE with Alberta license plate LVA 978. Her granddaughter, Zoe Cooper, reported that Diane has mild dementia but is mostly herself, raising concerns about her well-being given her unusual disappearance.
According to the RCMP, Cooper’s last known location was just outside Veteran, Alberta, where she was seen traveling east on Highway 12 around 9:30 p.m. on April 6. The search efforts have expanded across Alberta and Saskatchewan, with detachments from both provinces involved in the investigation. Police have received tips from various regions, including Alberta, Saskatchewan, and British Columbia, but none have been confirmed as credible leads.
Cooper is described as five feet three inches tall, weighing about 100 pounds, with a slim build, white hair, blue eyes, and wearing eyeglasses. Her family is deeply concerned for her safety, as her disappearance is out of character. Zoe Cooper expressed the family’s distress, stating, “We miss her so much. We just want her back.” This sentiment resonates with many who understand the emotional toll of a loved one going missing.
Cpl. Teri-Ann Bakker of the RCMP noted, “The most credible information we have right now suggests that Diane Cooper was actually in Saskatchewan.” However, it remains unclear where she was heading when she crossed into the province, and the reason for her travel to Saskatchewan has not been confirmed. Details remain unconfirmed.
Authorities are urging anyone in rural Alberta or Saskatchewan to keep an eye out for Cooper, as her family continues to hope for her safe return. The search for Diane Cooper highlights the importance of community involvement in missing person cases, as public awareness can often lead to crucial information.
As the investigation continues, the RCMP and Cooper’s family remain hopeful that someone may have seen her or her vehicle. They encourage anyone with information to reach out to the Consort RCMP at 403-577-3001. The urgency of the situation underscores the need for vigilance and support from the community in the search for Diane Cooper.
