The closing arguments have now concluded in the case of a Nova Scotia man accused of killing his fiancée.

The Crown and defence wrapped up their cases today at the Nova Scotia Supreme Court in Bridgewater.

Yesterday the court heard that 47-year-old Laura Lee Robertson died during a night of drunken sex with her fiancé, 33-year-old James Leopold.

Robertson disappeared in April, 2011. Her body was discovered about two weeks later in a wooded area in Greenfield, N.S., close to where the couple had been living.

Leopold was arrested and charged with second-degree murder shortly after her body was found. He has pleaded not guilty to the charge.

The 12-person jury watched a nine-hour video of Leopold being interviewed by police. In the video, taken 12 days after Robertson was killed, Leopold tells police Robertson intentionally bit his genitals during oral sex.

He told police he reacted and struck her in the neck but said it was an accident and he never meant to kill her.

"I didn't even know it was gonna happen and then it's too late, you can't take it back," said Leopold in the video. "I'm not a killer. I'm not some sick bastard who goes around killing people. This was an accident."

Today the Crown argued that Robertson's murder was a prolonged, intentional act.

"The Crown's theory is that he was acting out of anger when he killed her," said Crown prosecutor Leigh-Ann Bryson. "He indicated that there was a bite that took place, and the Crown submitted to the jury that he acted in anger, the culmination of all of these arguments. However, he made the choice to kill her, to end her life."

The defence did not call any witnesses to the stand but did not explain why.

Defence lawyer Chris Manning presented graphic photographs to the jury, which he said portrayed Leopold's injury. He told jurors that Leopold was provoked and that he did not commit murder, but instead reacted to a painful injury.

"I don't think you could hear a more frank, honest account than the one that was given to you by Mr. Leopold," he said in court, referring to the police interrogation video.

The jury is expected to begin deliberations tomorrow.
