CALGARY - A six-week trial has been scheduled for next year for a Calgary couple charged with manslaughter in the death of their grandson.

Allan Edgardo Perdomo Lopez and Carolina Del Carmen Perdomo were charged in July and remain free on bail.

The judge-alone trial is scheduled to begin May 1, 2017.

The charge relates to the death of Emilio Perdomo.

The five-year-old boy was taken to the Alberta Children's Hospital on July 10, 2015, suffering from injuries family members attributed to numerous accidents.

He died a week later and an autopsy concluded his death was the result of multiple blunt-force trauma injuries.
