A WOMAN obsessed with serial killers and her bondage-loving housemate were today jailed for life for murdering 18-year-old Kwinana teen Aaron Pajich-Sweetman.

Jemma Victoria Lilley (26) and her housemate Trudi Clare Lenon (44) lured Mr Pajich to their house and stabbed him to death in a “thrill kill”.

Lilley, a would-be serial killer, and Lenon, a mother-of-three, will not be eligible for parole for 28 years.

Mr Pajich had trusted Lenon because he was friends with her young son.

Aaron Pajich-Sweetman.

WA Supreme Court Justice Stephen Hall said the women’s crime was morally repugnant and would create feelings of “horror and revulsion” in right-thinking people.

The pair buried Mr Pajich in a shallow grave, covering it with concrete and tiles, on June 13, 2016.

Justice Hall told Lilley and Lenon their motive for murder was the “pitiless pursuit of your own desires”.

He rejected much of what both women’s lawyers put forward as mitigating factors after Lenon’s lawyer argued her client would suffer extra punishment in prison after she was taken Fiona Stanley Hospital on January 2 after being attacked and badly burnt at Bandyup Women’s Prison.

He also rejected mitigating factors for Lilley such as youth, that she had received threats in prison or that she had been led by Lenon.

“None of those factors are relevant in your case. You had migrated to Australia on your own and lived independently for many years,” he said.

“There’s nothing to indicate that you were gullible or easily led. To the contrary. You were very much the driving force in this offence, and you plainly understood the consequences of your actions.”

“In my view your youth is not a factor to which any great weight can be given.”

Justice Hall made particular note of one psychiatric report for Lilley and rejected she was of ‘moderate risk’ of re-offending.

“Although you did not reach the overall threshold for psychopathy due to the lack of an antisocial lifestyle, you did achieve the maximum score on another factor… a psychopathic, narcissistic personality,” he said.

The crime shocked the people of Kwinana with its brutality and his death resulted in an outpouring of grief from the community.

A vigil was held for Aaron Pajich-Sweetman on June 23, 2016.

The women blamed each other for the murder, but in November last year a jury took less than three hours to find them both guilty after a four-and-a-half week trial in the Supreme Court of WA.

Lenon knew Mr Pajich was a friend of her 13-year-old son and she also went to the same college as him, but Lilley only met him on the day of his death.

The jury was offered counselling following the trial, with Justice Hall describing the evidence as ‘disturbing and confronting’.

Lilley’s lawyers revealed their client intends to appeal her conviction.
