not sure if people are familiar with Karla Homolka but she was found guilty and served 12yrs i think for participating in the murders of her younger sister and two teenage girls..the torture/murder/sex slayings were video taped and made their way to the internet and even though the public was outraged by her release and i believe she received death threats..Karla now has a baby of her own and lives a relatively nice life in Montreal.
she changed her name so not sure of current info on her
