The Crown took Claude Larouche to task Tuesday, attacking his version of events that led to the death of Natasha Cournoyer two years ago.

Larouche is accused of kidnapping and murdering Cournoyer in October, 2009, then hiding her body in a field in Pointe-Aux-Trembles.

While testifying in his own defence on Monday, Larouche admitted to killing her, but claims he was so high on cocaine at the time that he had no idea what he was doing, that her death was accidental, and that he did not realize she was dead until the next morning when he discovered her body in his van.

Crown prosecutor Eliane Perreault cross-examined Larouche on Tuesday morning, and did her best to poke holes in his story.

Larouche said that he was doing drugs in his van in the parking lot when he was approached by Cournoyer, and that she agreed to go back to his motel room and have sex.

Perreault asked Larouche if Cournoyer was screaming or crying during the incident.

"These are big words," Larouche answered. "I can't really say. If I say no, I'm a liar. And if I say yes, I'm also a liar."

When asked if Cournoyer screamed when he grabbed her near the car, Larouche responded he wasn't sure who was doing the pushing. He also said he couldn't remember whether or not he tied Cournoyer up.

"It's possible," he said. "But I don't remember."

A fidgety Larouche often stuttered as he answered, and even showed aggressiveness when he couldn't come-up with answers.

Still, Perreault pushed forward as Larouche's answers to her questions continued producing more contradictions.

She revealed Larouche's answers given during six hours of police interrogation after his arrest on Nov. 5, 2009.

Police asked Larouche how he could explain his DNA being on Cournoyer's body, and if he was hunting women that night.

"Keep working on your puzzle," Larouche allegedly responded. "If I want to kill someone, I'll go hunting. If I want sex, I also know where to go."

Larouche was also challenged by Perreault on his selective memory.

"I clear a path in front of me based on the evidence you show me," he responded.

Larouche's defence will present its final witness to the stand Wednesday, a toxicologist expected to provide testimony that will bolster the defence's argument that Larouche was too high on cocaine to have had any intention of killing Cournoyer.
