Sentencing submissions for Alberta man accused of killing his partner’s sister in Rocky Mountain House

Court heard that a central Alberta man who admitted he killed his common-law wife’s sister during a domestic dispute shot the victim as she was trying to protect her sibling.

Marshall Stone, 47, pleaded guilty in June to second-degree murder and unlawfully discharging a firearm in the death of 28-year-old Ashley Smith-Ames.

Stone was in a relationship with her sister, Alexis Ames, and the three were living together in a townhouse in Rocky Mountain House, Alta., in July 2019 with three children between the ages of four and 10.

An agreed statement of facts presented in a Red Deer courtroom said Stone had been drinking before he got home from work, and started arguing with his partner while the children were watching TV in the next room.

The statement said Stone retrieved a rifle from downstairs and started pointing and shooting at Ames, who was not hit.

It said the sisters started screaming at Stone as he reloaded the rifle and again pointed it at Ames, but Smith-Ames stepped between them and was shot.

The children ran out the back door of the home, screaming for help, while Ames picked up a chair and hit Stone with it, the statement said. She was cut on the head during a brief struggle with Stone before she ran out the front door.

Court heard Smith-Ames had been shot through the eye, and was still alive and on the floor, when Stone shot her again in the back of the head.

An autopsy determined she may have survived after the first gunshot, but the second was fatal.

Stone turned himself in to the RCMP later that night. He told officers he had little memory of the shooting, the agreed statement of facts said.
