Karla Homolka, serial killers in canada? thanks in advance

especially contact information?

I have heard of them, weren't they called the Ken and Barbie killers?

You're absolutely right. Paul and Karla were known as the "Ken and Barbie" Killers in Canada. Their crime spree began in the late 80's with a series of rapes, and went into the mid-1990's with three murders.

Their hand at murder began with Karla's younger sister, Tammy, who was killed while being subjected to rape by Paul. He had become angry that Karla was not the virgin she professed to be, and demanded that he be given a virgin....Karla's sister Tammy.

Karla had worked for a veterinarian, and obtained some halothane, which is used to sedate animals before surgery. The plan was to put Tammy to sleep, so Paul could rape her. Unfortunately, she vomited, and choked to death.

Paul's crime spree actually began shortly after he met Karla in about 1987. After about 12 rapes, Karla began participating in his rapes. Karla video-taped them frequently.
