Late summer 2012: 94-year-old Hazel Lloyd was found dead inside her Medicine Hat, Alberta, apartment after a fire. Investigators determined the blaze had been deliberately set, but that the fire was not the cause of death. An autopsy found she died of blunt force trauma, and the Medicine Hat Police Service opened a major crimes investigation.

No one has been arrested or charged. Ten months after the death a $10,000 reward was offered for information leading to an arrest and conviction, and nearly two years later police released composite sketches of three men described as people who might have information, not identified suspects. The case remains unsolved and open.

If anyone knew Hazel, was in that neighbourhood in late summer 2012, or has information about the three men or the fire, please share what is known with investigators.
