Lawyers wrapped up closing arguments Friday at the Mark Dobson murder trial.

Dobson is facing two counts of first-degree murder for the deaths of his girlfriend Mary Hepburn and Helen Dorrington at a Barrie hotel in 2012.

Throughout the trial, the court heard Dobson had made satanic murder-suicide pact with the women which didn’t go as planned.

The Defence says Dobson suffers from schizophrenia and should be found not criminally responsible but the Crown argues Dobson knew his action were legally and morally wrong.

The judge will render a verdict in December.
