The trial of a Canadian soldier accused of trying to kill her children by setting fire to her CFB Edmonton home continued Monday, where former CFB Fire Chief, Joseph Mayer, and investigator, Jean Grenier, testified. Crown prosecutor Dallas Sopko said the fire was the final act in a bitter custody battle. The woman — who cannot be identified under a publication ban to protect the identities of the children — faces two counts of arson and three counts of attempted murder related to the 2015 fire.
