Yesterday they stood to face Justice Terry Macklin in the dead hush of Court of Queen's Bench and paid the price. The brothers-in-law pleaded guilty to four counts of manslaughter in the deaths of the four Mounties Roszko ambushed, shot and killed inside his Quonset hut outside Mayerthorpe on March 3, 2005. They had been charged with first-degree murder but agreed to plead down to the lesser charges. Manslaughter generally carries a lighter penalty than the mandatory life sentence for first-degree murder. Hennessey, 29, dressed in a grey suit and striped white dress shirt, hair cut to a razor-thin black stubble, quietly replied "Yes," to the four counts of manslaughter relating to the deaths of constables Anthony Gordon, Brock Myrol, Peter Schiemann and Leo Johnston. Cheeseman, 25, then stood in a white dress shirt and black slacks, hands behind his back, dark hair parted in the middle and highlighted by blond streaks, and replied "Yes" to the four counts. The men, who had been free on bail, were then ordered held in custody. "For the people who worked with the fallen four, they will also see today that justice was served," said RCMP spokesman Cpl. Wayne Oakes outside court. The courtroom was packed with more than 100 people, some standing in jammed doorways. Family members of the victims looked on, dabbed teary eyes or quietly cried as Crown prosecutor David Labrenz recounted the events surrounding the ambush in an agreed statement of facts.
