No, seriously. Katherine Knight, a former slaughterhouse employee killed her (possibly sleeping)boyfriend with a butcher knife, skinned him, hanging his flesh on a meat hook, and cooked parts of his body, having set the table for his children (Like a reverse Titus Andronicus) in 2001. There were also "snuff" movies in the house.
Now she's trying to plead with Australian courts to overturn her life sentence because she's a woman, among other, rather flimsy reasons. She's known in prison for her "demure behaviour".
Knight has a history of violence in previous relationships and marriages, among other things killing one ex's puppy and smashing another's false teeth.
Sounds like a really pleasant lady. http://www.dailytelegraph.news.com.au/story/0,20281,19585040-5001022,00.html
