Jason Bruce Cardinal Pleads Guilty To First-Degree Murder, For Killing His Two Young Sons During Custody Battle


EDMONTON - An Edmonton man has admitted to killing his two young sons nearly two years ago.

Jason Bruce Cardinal, 33, pleaded guilty Friday to two counts of first-degree murder.

Police found the two boys, aged three and six, dead in a townhouse in northeast Edmonton on Dec. 20, 2010.

A statement read in court said that the children were strangled to death. Cardinal was planning a murder-suicide weeks before the boys were found dead, CTV reports.

The boys were in the middle of a custody dispute and tests showed that Cardinal had sedated them with morphine before strangling them, according to the Edmonton Journal .

The children's mother told the court that Cardinal was “the weakest coward I have ever known."

A conviction of first-degree murder carries a sentence of life in prison with no chance of parole for 25 years.

A sentencing date has yet to be set.
