Two lesbian lovers, one who drank blood as part of a vampire culture, were sentenced to life in prison on Friday for what an Australian judge said was the "evil" killing of a girl they bludgeoned to death with a concrete block.
Jessica Stasinowsky, 21, and Valerie Parashumti, 19, pleaded guilty to murdering 16-year-old Stacey Mitchell in Perth in western Australia in 2006 because she was annoying, reported Australian Associated Press form the court in Perth.
Judge Peter Blaxell said the murder was "sexually perverse" and "evil", after the court was told the two lesbian lovers became sexually aroused as they battered the teenage girl and then kissed while standing over her body as she lay dying.
"You have each had more than a year in custody to reflect upon the evilness of your crime, yet you still lack remorse and obviously place no value on the sanctity of human life," Blaxell said in handing down the life sentences.
"There is also the added problem that you each enjoy being sexually aroused by the infliction of violence," he said.
When Stacey moved into a house the lovers were sharing, Stasinowsky immediately hated her because she thought the teenager was flirting with her lover, the court heard.
Parashumti felt the need to prove that Stacey meant nothing to her, so she and Stasinowsky decided to kill her.
On the day of the murder, the trio drank whiskey in the kitchen and Stacey took tablets which made her drowsy.
Parashumti crept up behind Stacey and started hitting her on the head with a concrete slab, while Stasinowsky took off a dog chain belt and began to strangle her.
Stacey took at least 45 minutes to die, but Stasinowsky later told a prison officer she wished it had lasted longer.
"Even more appalling are your admissions to the effect that at the time of the murder you were each sexually excited by the violence of the event," said Judge Blaxell.
The killers made a mobile phone video of the murder scene, laughing and mocking their victim, and then dumped her body upside down in a garbage bin in a back shed.
A psychologist found Parashumti, who drank blood as part of a vampire subculture, had very strong sexual sadistic tendencies and was sexually aroused by physical torture and violence.
