The Crown is seeking a dangerous offender designation for a Winnipeg man convicted of confining, raping and torturing his two daughters for seven years.
Court was told the man filmed many of the assaults.
The 48-year-old pleaded guilty Thursday to 11 charges including sexual assault causing bodily harm, making child pornography and forcible confinement.
He cannot be named to protect the identity of his daughters.
The girls were between the ages of nine and 16 during the years the assaults took place.
Evidence submitted to court indicate that a police officer who interviewed the man after his arrest was unable to hide his contempt.
"We're not going to leave any of this out (in court) because we're going to paint the picture of the monster that you are," the officer told the man.
"Who does this to their own kids? A coward. That's who does it, a coward. Do you not feel anything for these kids? It just breaks my heart."
Police raided the man's apartment in Sept. 2011 and seized computer equipment containing 2,609 photos showing the man raping the girls.
An additional 125,000 images of child pornography were also seized of unknown children – including babies – being sexually abused.
If the man is now found to be a dangerous offender, it means he would be given an indefinite prison sentence with no guarantee of ever being released.
The police investigation began when one of the girls walked into a police station last fall after disclosing the abuse to her boyfriend.
"Nobody should ever have to feel this way," the woman, now 21, said in her police interview. Her sister, now 19, gave a statement days later.
The girls typically spent much of their summers with the accused, who had separated from their mother.
The court was told he used a points system which assigned certain values to various sexual acts they would perform, outfits they would wear or toys they would use. He would then reward them once they hit certain goals.
"He always used bribes," one of the daughters told police. "Eventually we'd get enough points to go on a trip."
The two girls often begged their father to stop, even writing him letters when they were in their early teens.
"Dear Daddy, I love you more than you'll ever know. That's why I think we should stop what we do," one letter presented to the court read. "We can still cuddle and stuff, just not the hardcore stuff. I'm sorry if you're mad."
