MONTREAL - It's been nearly a month since a Quebec man who killed his two children was found not criminally responsible -- and the public outcry over the verdict is still palpable.

That anger will be on display this weekend, as people demonstrate at 14 cities across Quebec on Saturday.

They are protesting a jury's decision in the murder case of Guy Turcotte, a former cardiologist who admitted to fatally stabbing his children. He stabbed them 46 times, while they were lying in their beds.

But Turcotte says he never actually planned to kill his kids and can't recall committing the act. He says he was so distraught over the fact that his wife had left him for another man, that he wanted to die.

The prosecution now says it's appealing the verdict.

The Crown argues that the judge erred in his instructions to the jury and it has asked the Quebec Court of Appeal to hear the case.
