On the fourth day of the trial of a Millet mother charged with taking the lives of her two young boys, the Medical Examiner took the stand.

Dr. Bernard Bannach talked about the autopsies he performed on the bodies of the two young boys, 2-year-old Connor and 10-month-old Jayden, and confirmed both boys died as a result of drowning.

Throughout the trial so far, Crown Prosecutor Gordon Hatch has been attempting to prove a conviction for second-degree murder for the accused, Allyson McConnell, is warranted.

"Essentially what I want to establish is that Ms. McConnell was able to make certain plans," Hatch said outside Wetaskiwin Provincial Court. "If she was able to plan her suicide, then she was also able to plan the deaths of her children,

"Planning, not in the sense of first-degree murder obviously, but to show that she has the ability to formulate certain ideas in her mind."

The trial stems from the gruesome discovery of the two young children, who were found dead by their father, Curtis McConnell on February 1, 2010.

The boys had been drowned in the bathtub of their family home in Millet - the accused has since admitted she drowned her sons – but has pleaded not guilty to the two second-degree murder charges laid against her.

The trial is expected to continue Monday, McConnell's defence lawyer is expected to call witnesses.

It's believed Allyson McConnell could take the stand.
