Episode 241: On March 3, 2005, a contingent of RCMP constables attended the property of James Michael Roszko, 46, in Rochfort Bridge, near Mayerthorpe, Alberta. The members were there to serve a search warrant for stolen property and a marijuana-growing operation on the farm, discovered the day before. Roszko, knowing the police would be arriving soon, armed himself with the help of a couple of friends, Shawn Hennessey and Dennis Cheeseman, and then he lay in wait for the RCMP. When four of the officers, Anthony Gordon, Lionide “Leo” Johnston, Brock Myrol and Peter Schiemann, walked into a quonset hut on the farm. Roszko, hidden inside the building, opened fire on the four members, killing them and then himself before the other RCMP members on-site could come to their aid. 
This episode covers the life of the murderer and leads us up to the slaying of the four RCMP members. Next week in part 2, you’ll hear about the crime and its aftermath.
