MONTREAL - A woman whose two children were killed by her estranged husband says she supports prosecutors' decision to seek leave to appeal the verdict at his trial.

Earlier this month, a jury found former cardiologist Guy Turcotte not criminally responsible in the stabbing deaths of his five-year-old son and three-year-old daughter.

The verdict shocked Quebecers. At the time a shaken Isabelle Gaston, the children's mother, announced she would not sit through another trial if the case went to appeal.

But Gaston issued a statement today saying she has changed her mind.

She says she wouldn't be able to live with herself if she didn't do everything she could to denounce what she believes were legal errors.

The Crown announced last Friday that it is seeking leave to appeal the verdict because it believes the judge erred in law in his instructions to the jury
