The ex-wife of Guy Turcotte said she is frustrated and afraid while waiting for the bail ruling on child killer Guy Turcotte. 

The Crown is making a final attempt to keep Turcotte behind bars while he waits for a second trial for the murder of his children.

He faces two new counts of first-degree murder after a jury found the former cardiologist not criminally responsible in 2011 for murdering his children Olivier, 5, and Anne-Sophie, 3, in a home north of Montreal in early 2009.

Turcotte was granted bail in September pending a new trial set to begin in September 2015, after the prosecution asked Quebec's highest court to revisit the decision.

The Crown argues that releasing Turcotte on bail undermines the public's faith in the justice system.

When granting Turcotte bail, Justice Andre Vincent ruled that Turcotte was not a threat to himself or anyone else.

Turcotte’s ex-wife, however, came to the Court of Appeal Monday, and told reporters outside that her goal is to keep her ex-husband off the streets and behind bars, saying it’s not normal for a child killer to be allowed out.

“I have nightmares that he'll attack me," she said, adding she’s been frustrated and afraid since Turcotte was allowed out.

“If he goes out, I know I’m alone to defend myself.  Not the police, not the tribunal, not Pinel (Institute), nobody. I know I'm out like in the jungle,” she said.

Vincent argued that Turcotte is entitled to the presumption of innocence as he awaits the new criminal proceedings.

Quebec's three Court of Appeal judges did not say when they are expected to rule on the bail issue.

Turcotte spent 18 months in a psychiatric institution before being released in 2012 after the 2011 ruling.

Last year Quebec's Court of Appeal ruled the judge in the case had made an error in instructing the jury, and so ordered Turcotte to undergo a new trial.

Psychiatrists who treated Turcotte said that he went into major depression when he learned of the retrial.

He was said to have shown psychotic symptoms including paranoia, he thought a guard was after him and he’d hide in his room.

However, when granting Turcotte bail, Justice Vincent said Turcotte's mental health issues are being well-regulated.

While on bail Turcotte is helping take care of his aunt and uncle.
