A British Columbia man is facing more than a decade in prison for his role in a drug-trafficking operation after police seized more than 12 kilograms of illicit drugs, including carfentanil, in the Fraser Valley. Tyler Shawn Missen, a 36-year-old resident of Langley, was charged last month with multiple offences, including six counts of possession for the purpose of trafficking and possession of a restricted or prohibited firearm. Missen pleaded guilty on Aug. 26 and was sentenced to 11 and a half years in prison, the RCMP said in a news release Monday. With credit for time served while in custody, he has approximately 10 years and 10 months remaining on his sentence. Missen was arrested following a lengthy police investigation, dubbed Project Interruption, which began in April 2025 after patrol officers in Abbotsford arrested him for driving while prohibited. During the traffic stop, police say they found illicit drugs and a pistol in his possession. The discovery led investigators to obtain search warrants at several properties, including a home in the 31100 block of Deertrail Drive in Abbotsford, according to local police. The searches uncovered more than 12 kilograms of illicit drugs, including carfentanil, cocaine and methamphetamine, according to a July 9 statement from the Abbotsford Police Department. Investigators also seized vehicles, more than $60,000 in cash, body armour, a handgun and several loaded magazines. “The quantity of drugs seized, particularly carfentanil—a highly potent synthetic opioid—had the potential to cause significant harm within the community,” the AbbyPD statement said. The RCMP said Monday it will seek a forfeiture order through the courts for property seized during the investigation. “This sentence reflects the serious consequences associated with trafficking dangerous drugs and illegally possessing firearms,” Cpl. Stephan Mendela of the Chilliwack RCMP said in a statement. “This investigation removed significant quantities of harmful drugs from our communities and demonstrates the impact of strong partnerships between law enforcement agencies.”
