The man at the centre of an alleged rape case involving a woman with Down's syndrome did not take the stand on Wednesday, meaning he will not be testifying in his defence.

Serge Levac is HIV-positive, and is accused of raping a 47-year-old woman who functions at the level of a child. She lives alone but relies on the help of a social worker.

He faces charges of aggravated sexual assault, death threats, and weapons possession.

After the crown wrapped up its arguements, Levac's lawyer decided not to call any witnesses at the last minute.

The move allows the lawyer to plead last.

The trial

During the trial the woman described the alleged incident in detail. Police and witnesses say that Levac lived in the woman's building. They say last October he convinced her to let him into her apartment and then raped her.

The defence says the woman's testimony is not reliable because she is intellectually handicapped. He reminded the court that legally, the proof must be strong enough to convict Levac beyond a shadow of a doubt.

There was no DNA evidence in the case because the woman told her social worker a few days after the incident. Samples were taken at that point.

Other incidents

When the social worker alerted police, they arrested Levac and issued his photo to the public.

Police say other victims have come forward and that Levac will likely face new charges.
