A Canadian reservist charged in a fatal training accident in Afghanistan will have to wait another day to see if the military jury weighing his fate has reached a verdict.

The Calgary court martial jury wrapped deliberations for the day on Monday afternoon, and will resume on Tuesday.

Maj. Darryl Watts, 44, faces charges that include manslaughter, unlawfully causing bodily harm, breach of duty and negligent performance of duty.

Cmdr. Peter Lamont, the military judge overseeing the court-martial in Calgary, delivered a two-hour charge to the five-member jury panel late Saturday afternoon before sending them out to begin deliberating.

The jury is being sequestered until a verdict is reached, but gets to decide on its own timeline of when to break for the night and resume in the morning.

Tuesday will mark the fourth day of deliberations.

Cpl. Josh Baker, 24, died and four other soldiers were injured when a Claymore anti-personnel mine, packed with 700 steel balls, peppered their platoon on a training range near Kandahar City in February 2010.

The Crown argues that Watts, who was the platoon commander, turned a blind eye to safety standards and abdicated his duty as a leader during the exercise.

The defence countered that Watts had no training on the Claymore, so he handed over responsibility for safety to his second-in-command, who was an expert on the weapon.
