A 26-year-old woman in Australia who is accused of murdering an 18-year-old autistic man reportedly planned the murder because murdering someone was on her “bucket list.”

Supermarket night manager Jemma Lilley is accused of murdering Aaron Pajich last June, with the help of her “obsequious and sycophantic mate” Trudi Lenon, 43, a prosecutor alleged.

The Australian court heard how Lilley and Lenon, a mother of three, had established a relationship in which Lilley was dominant while Lenon was submissive. According to perthnow.com:

Ms. Lilley was referred to as SOS – which was also a serial killer character in a book she had written in her teens, and also the name of an American serial killer who had murdered eight victims in the mid 70s’. Ms. Lenon was known as “Corvina,” a name she had adopted through her participation in bondage and sado-masochistic sex.

Lilley allegedly wrote to Lenon, “I feel that I can’t rest until the blood of a fresh, screaming, bleeding victim is gushing out and pooling on the floor.”

According to prosecutors, once the women had moved in together along with Lenon’s three children, they targeted Pajich, whom Lenon knew through his friendship with her teenage son Cameron. Prosecutor James McTaggart said Pajich “still inhabited a child’s world” and was obsessed with computer games.

The state alleged that Lenon lured Pajich to his death; McTaggart said, “Trudi Lenon delivered Aaron Pajich right into Jemma Lilley’s hands and together they murdered him. These two ladies took Aaron Pajich’s life in a way that was as brutal and violent as could possibly be imagined.” He alleged that Pajich was lured to the house to see Lenon’s 14-year-old son, to give him some new computer games; then Lilley attempted to strangle him with a garrotte before Lenon held him down while Lilley stabbed him to death.

McTaggart referenced an alleged remark Lilley had made to a friend years before that her “life’s objective” was to kill someone before she was 25. He added, “That cruel, inhumane and totally dysfunctional objective had been on her bucket list.”

Lilley’s workmate, Matthew Stray, told the state that Lilley had been “so full of herself, so exuberant that she had done this,” adding that days after the murder, she told him, “I did it, I killed him.”

Lilley told the court Lenon had brought Pajicj to their house to “train” him in BDSM.
