Why boxing legend Danny Green is wishing a "slow death" on a jailed murderer.

On Facebook yesterday, Australian boxing champion Danny Green posted an angry rant against Trudi Lenon.

Lenon, a convicted killer and mum-of-three, had boiling water poured on her in a Perth jail by a fellow inmate. She is currently in hospital with burns to 30 per cent of her body.

Green praised the person behind the attack and wished a “slow and obscenely painful” death on Lenon. So what’s the background to Green’s post?

What Danny Green said

News broke yesterday morning that Lenon, an inmate at Bandyup Women’s Prison, had boiling water from a kettle thrown at her by another inmate on New Year’s Day.

Lenon was in jail awaiting sentencing for the murder of autistic teenager Aaron Pajich-Sweetman. Lenon, along with 26-year-old Jemma Lilley, killed Pajich-Sweetman in 2016.

Soon after the news broke, Green posted on Facebook, under the heading “jail justice”. He described the jail attack on Lenon, calling her a “mutt”, and saying she’d murdered an innocent 18-year-old “in absolutely disgusting and horrific circumstances”.

“My hat is off to whoever carried out this act,” he wrote. “I’m tired of our putrid constitution forcing the law into the hands of the community.

“This poor young man. The way his life ended was just incomprehensible.

“I hope you get an infection and die a horrid and slow and obscenely painful death, you foul mutt.

“I’m willing to write what many think.”

Background to the case

Lenon and two of her sons shared a house with Lilley in the Perth suburb of Orelia.

Lilley was fascinated by knives, violence and serial killers. She had written a novel about a serial killer called SOS. Lenon had been into BDSM, and was a submissive called Corvina.

The two women had developed a relationship where they called each other SOS and Corvina. Their Facebook messages to each other talked about killing, darkness and torture. One of Lilley’s messages to Lenon had begun, “I feel as though I cannot rest until the blood of a fresh, screaming, pleading victim is gushing out and pooling on the floor.”

Pajich-Sweetman loved computer games.

He had just moved out of home and was living as a lodger with a woman he’d met at his church.

He knew Lenon and her 13-year-old son. The son described Pajich-Sweetman as “a really excellent friend”.

On June 13, 2016, Lenon dropped her sons at school and called Pajich-Sweetman, inviting him around to download computer software. He willingly met up with Lenon and Lilley, thinking he was going to see his friend.

Instead, once the teen was locked inside their house, the two women attacked him from behind with a garrotte and then stabbed him to death. They buried him in the backyard, and tiled over the area where he was buried. Lenon got her son to help with the tiling, with the young boy having no idea he was covering up the body of his friend.

Lenon and Lilley were found guilty of murder in November, and are due to be sentenced in February.

Why Green spoke up

Green has a history of campaigning against violence. He was behind the push to get the one-punch attack to be known as the “coward’s punch”. In 2012, the “senseless” death of a youth in his home town of Perth spurred him into making a self-funded TV commercial. He has contacted several families who have lost loved ones to one-punch attacks.

“To strike another human who has no idea it’s coming is mindblowing gutless,” he once said. “No one respects it. You are a maggot.”

Reactions to what Green said

Pajich-Sweetman’s stepmother, Veronica Desmond, was quick to respond to Green’s Facebook post yesterday.

“Thank you for your support, Danny,” she wrote. “Life is very difficult now, much more than it was.”

Meanwhile, Pajich-Sweetman’s aunt, Trinity Sweetman, also posted a reply, saying Lenon needed to be “tortured every single day” for what she did to her nephew.

“RIP Azza,” she added.

Many of Green’s followers were in full support of what he said. Some suggested he should run for parliament. However, a few people were critical of his post.

“So you give props to someone committing a violent act?” asked one.

“Regardless of the victim, violence is NEVER okay and never be condoned.”

“You’ve lost some of my respect,” added another.

“Keep up the good fight, Green Machine. Leave the hate for the haters.”
