Stonewall RCMP were called to the prison at about 7:30 p.m. Monday and said charges against the 21-year-old are anticipated but haven’t yet been laid. Police are still investigating with help from Correctional Services Canada.

Korski was serving a life sentence for the drug-related slaying of 20-year-old Wilson Martinez, who was shot dead on Sept. 16, 2004, in the Heritage School playground at Heritage Boulevard and Carriage Road in Winnipeg.
