Nearly four years after their father and uncle were killed in shooting, an Alberta family is now struggling with a rare disease diagnosis.

Roger Bilodeau, 58, and his son Anthony Bilodeau, 33, have each pleaded not guilty to two counts of second-degree murder. 

The widow of Jacob Sansom is still at a loss on what could have happened to lead to her husband and his uncle Maurice Cardinal being shot to death on a rural road in northern Alberta two months ago.
