When Amanda and Sabrina Sorella were found dead in the family home in March 2009, it was the start of a long, strange story. Their father was on the run, wanted for involvement in organized crime. Their mother was barely coping alone, had attempted suicide and said she had no memory of the day the girls died.

Denise Thole cannot understand why her brother was left unsupervised just four days after a suicide attempt. A doctor had recommended he be under 24-hour watch but a shift change at shower time left Stone alone for long enough for him to take his life.

Closing arguments wrapped up Tuesday in the Nunavut Court of Justice, where a 21-year-old man is being tried on charges of second-degree murder in the death of a young boy in 2017.
