Deliberations in the Adele Sorella murder trial resumed on Sunday.

Members of the jury have four possible verdicts to consider.

  • First-degree murder
  • Second-degree murder
  • Manslaughter
  • Acquittal

Sorella is accused of killing her two daughters in the spring of 2009.

The grandmother of Amanda, 9, and Sabrina, 8, found the sisters’ bodies lying side by side in the family’s home in Laval.

The bodies showed no signs of violence and the cause of their deaths remains unknown.

The Crown suggested the girls could have been killed inside a hyperbaric chamber, which the family had on-hand to treat the youngest daughter's juvenile arthritis.

The defence argued that no traces of clothing fibres were found inside the chamber.

Sorella is being defended by lawyer Pierre Poupart, who also represented Guy Turcotte.

The former St-Jerome cardiologist was found not criminally responsible in the killing of his son and daughter.
