A TEENAGE schoolgirl slaughtered two kittens in preparation for the cold-blooded and premeditated murder of her friend, a Perth court has been told.
In what has been described as a callous and vicious attack on 15-year-old Eliza Jane Davis, her two "friends" strangled her with a piece of speaker wire while holding a chemical-soaked cloth over her mouth...
...there appeared to be no motive for the frenzied attack on the teenager.
One of the girls had told police: "We knew it was wrong, but it didn't feel wrong at all, it just felt right."......Eliza was... grabbed from behind and a piece of speaker wire was wrapped around her neck twice and pulled tightly.
"The only thing I was thinking about was trying to pull it as tight as I could," the girl told police.
Once Eliza was dead, her body was pushed down a stairway and covered with sand in a 40cm grave underneath the house.
One of the girls reported her missing and even helped Eliza's mother in efforts to find her.
"As our friend, we did not really want her to suffer," one of the girls told police.
What am I missing about the effects of ice? I have a machine that makes the stuff and even grinds it up if I push a button. Maybe I better get rid of it.
We need to get control of ice and speaker wire!
[Prosecutor Simon Stone] said one of the girls and Eliza had taken ice the night before the murder but it was not an amount that would affect the girls' sense of right and wrong.
"At best there may have been a slight intoxication by the residual effects of the ice that was taken the night before.
