Teenager’s killers among WA’s worst
Jemma Lilley and Trudi Lenon were categorised as among WA’s worst killers last week as they were jailed for life for the sadistic and heartless thrill killing of autistic teenager Aaron PajichSweetman.
Their 28-year minimum jail terms are thought to be the highest imposed on female killers in WA — though both maintain their innocence, and Lilley will appeal against her conviction.
In a tense, tearful courtroom, the parents of the 18-year-old victim struggled to maintain their emotions as Supreme Court Justice Stephen Hall described the 2016 murder as “morally repugnant” and a “pitiless pursuit” of a thrill kill.
And in a chilling postscript, Justice Hall ordered the psychological and psychiatric reports compiled on Lilley be sent to prison authorities because of fears about a “possible scenario” of reoffending “and the steps that need to be taken to prevent the risk of that scenario becoming a reality”.
Lilley, 26, and Lenon, 44, were last year found guilty of the murder of Mr Pajich-Sweetman, who was lured to the Orelia home the pair shared and killed for fun.
The jury was told he was garrotted and stabbed with one of the many knives kept at the home, which was a shrine to Lilley’s obsession with serial killers. Mr Pajich-Sweetman’s body was hidden for days, wrapped and buried in a grave in the backyard, before it was crudely covered with concrete and tiles.
The killing was the culmination of Lilley’s years of sadistic desire to feel the thrill of a kill, which she had openly told friends about, and explored in a book she had written about a serial killer that she called SOS.
She also referred to herself by the same name, a homage to the US serial killer Son of Sam.
Justice Hall said that while he believed it was more likely Lilley had inflicted the fatal wounds, Lenon was equally culpable because she had lured the teenager to the house.
She had known Mr PajichSweetman through college, and he had been a friend of her son.
When Mr Pajich-Sweetman’s father Keith Sweetman was asked how his family were coping, he had just one word: “suffering”.
