DRUMMONDVILLE, Que. - A Quebec woman charged with killing her three children has been declared fit to stand trial.

Sonia Blanchette appeared in court today after undergoing a lengthy psychiatric evaluation.

Details of the psychiatric assessment were not revealed in court.

The 33-year-old Blanchette was arrested after two-year-old Anais, four-year-old Loic and five-year-old Lorelie were found dead in her Drummondville residence in early December.

She faces three counts of first-degree murder and is due to return to court on March 28.

Drummondville is midway between Montreal and Quebec City.
