AN ACCUSED woman in the murder trial of Rockingham teenager Aaron Pajich acted on an obsession she had with killing someone, the Supreme Court heard today.
Jemma Victoria Lilley (26) appeared along with Trudi Clare Lenon (43) on the first day of their trial for the murder of Mr Pajich on June 13, 2016.
The court heard Lilley acted out an obsession she had with killing someone, often role playing a character from a book she had written about called in 2009 called the ‘Playzone’.
The book was about fictitious serial killers and killings.
The women both entered pleas of not guilty, although Lenon stated she was guilty of being an accessory after the fact.
In his opening address, Crown Prosecutor John McTaggart said the State’s case was that Mr Pajich was brutally and violently murdered at the hands of the two accused.
“Either jointly or one aided the other and just a few days later Lilley joked and gloated about it with a work colleague at the Woolworths Palmyra store where she was a night shift manager,” he said.
“Mr Pajich died from sharp force injuries of stab wounds to the neck and chest.”
His body was wrapped in a drop sheet and entombed under a concrete slab with orange/red tiles on it which appeared out of place in the accused’s backyard.
Other things had been changed in the home including a couch being removed and a large piece of carpet cut out the living room and then covered with a rug.
Mr McTaggart said the attempts to conceal and clean-up after the murder were amateurish.
He said Lenon had met Mr Pajich through the Kwinana TAFE they were both attending.
As a result Mr Pajich became good friends with her 14-year-old son due to their shared interest in computers.
He said Aaron was considered to be high on the Autism spectrum, something that made him vulnerable to outside influences and caused him to associate with much younger people.
At 9.30am on the day he was murdered, Aaron got a call from Trudi. He was not expecting the phone call. He arranged for the person he lived with to give him a lift to Rockingham Shopping Centre.
That friend was the last person who saw him alive other than the accused women.
CCTV footage from the shopping centre and Lilley’s home showed him meeting up with the pair and about 20 minutes later arranging to go to Lilley’s Orelia home, which she had bought several months earlier.
He never came out again.
The State’s case is that he was killed the same day he went back to Lilley’s house.
Police believe he went there under the guise of computer-related work as his thumb drive was found in Lilley’s computer.
They also stated Lilley had told her work colleague that “it was harder than she thought it would be”.
Lilley’s defence lawyer told the jury that his client did not deny the murder – just her part in it.
He stated Lenon had been the one who carried it out and Lilley had been doing gardening in her backyard, not even knowing Mr Pajich was buried there.
Lenon’s lawyer claimed her client had helped Lilley after the fact, as she was frightened for her children and had run out of the room when Lilley allegedly killed Mr Pajich.
She said her client was involved with BDSM groups as a submissive and role played sexual fantasies and other fantasies.
The trial is set for five weeks.
