BARRIE, Ont. -- - Jurors deliberating the fate of a Barrie, Ont. woman who drowned her two young daughters has asked the judge to clarify a point in his legal instructions to them.

The jury in the trial of Elaine Campione, 35, asked for clarification about the judge's instructions pertaining to evidence about Campione's state of mind.

The judge is considering his response on the fourth day of deliberations in the case.

The defence concedes Campione killed her daughters Serena, 3, and Sophia, 19 months.

Her lawyers urged the jury to find her not criminally responsible by reason of mental disorder.

The Crown argued Campione killed the girls so her abusive ex-husband couldn't get custody.

This is the second question jurors have asked.

On Friday, jury members asked the judge to explain the phrase "morally wrong."

Justice Alfred Stong told the jury that to find her not criminally responsible they must believe mental illness rendered Campione incapable of knowing her actions were morally wrong.

The seven-week trial heard that Campione spent time in psychiatric wards, attempted suicide, had delusions that people were trying to kill her and steal the girls.
