In one of the most striking cases to ever be presented before the Perth Supreme court, the young Mr Aaron Pajich murder trial, both accused women, Ms Jemma Victoria Lilley, 26 years old, and her former housemate Ms Trudi Clare Lennon, 43 years old, continue to put the blame on each other.
Mr Pajich, who had autism, was found in a shallow grave beneath a freshly laid concrete slab just a week after he was reported missing. The former lesbian lovers both say the other did it. According to police, they led the young man to their Orelia home and murdered him the same day.
The trial enters it’s second week. Earlier, the jury had heard from state prosecutor Mr James MacTaggart that Ms Lilley had a keen interest in serial killers and had once informed a friend she wanted ‘to kill someone before she turned 25’.
Furthermore, Ms Lilley admitted she was writing a book about a serial killer character and for this had done a lot of research into the subject.
She admitted to wanting to write a trilogy on the issue and therefore all items found at her home, including a handwritten alphabetical list of torture methods, were part of her research.
"When I write for my books I look for techniques," she said, "there's a lot of torture in the books and it all gets a bit samey, so you have to think of new ideas."
Ms Lilley also explained that the various tattoos on her body were of serial killers used in her writing
Meanwhile police showed home security footage from Ms Lilley's home in court from the day Mr Aaron Pajich was allegedly murdered, which indeed showed the 18-year-old entering the house with the two co-accused women.
When the prosecutor asked Ms Lilley about the set of eight knives found in her bedroom, which included a bone saw and a machete, she responded using these for cooking.
Ms Lilley will be cross-examined in the coming days.
