A Melbourne man's methamphetamine addiction was no excuse for deciding he would try to rape a six-year-old boy at what he thought was a Los Angeles sex party organised by paedophiles, prosecutors have told a US judge.
Michael Quinn used internet to 'purchase' six-year-old boy to sodomise, prosecutor says
Prosecutor says 'no evidence' Quinn's drug use contributed to crime
Quinn pleaded guilty to travelling to US with intent to engage in criminal sexual activity
Michael Quinn, 33, an IVF geneticist arrested in an undercover sting in May while on a US rugby trip, will be sentenced in a downtown LA court on October 31.
Prosecutors recommended Quinn be sentenced to 12 years' jail and lifetime supervision when released.
"Despite the friendly, congenial mask defendant showed to the world, defendant lived a secret life online," assistant US attorney Joey Blanch wrote in a sentencing memorandum filed this week.
The court filing exposed publicly Quinn's addiction to meth, the extent of his sexual lust for children, a blog he wrote about sexually abusing children and plans he was making to meet "like-minded pervs" in New York.
"The government agrees with defendant that he is a drug user; however, there is simply no evidence that drug abuse contributed to his sexual interest in children or that it excuses or even explains his determined efforts to rape a six-year-old," Ms Blanch wrote.
'Aussie perv' social media post spotted by police
Quinn, who worked at a Melbourne IVF clinic and was in the US to play with the Melbourne Chargers rugby union team in the Bingham Cup in Nashville, was staying at a Hollywood Hills home he was renting with teammates on the first leg of the trip.
Quinn snuck away to the LA beachside hotel without his friends knowing and was arrested when he handed $US260 to an undercover agent posing as a pimp.
US authorities posing as paedophiles began communicating with Quinn in early May after he posted on a social networking site: "Aussie perv, heading to the US late May/June interested to meet others while I'm there. LA, Nashville, NYC".
Authorities said they found child pornography on his phone and also seized a meth pipe.
Quinn entered a guilty plea to a charge of travelling to the US with the intent to engage in criminal sexual activity.
The US Probation Office recommended a 10-year sentence.
An Orillia, Ont., man who pleaded guilty to molesting children as young as two years old has been labelled a dangerous offender and sentenced to prison indefinitely.
Shayne Lund, 25, pleaded guilty to 34 of the 100 charges he initially faced when arrested in 2013.
In approving the dangerous offender application, Justice Joseph Kenkel said Wednesday morning that the Crown proved beyond a reasonable doubt that Lund is a high risk to reoffend.
Shortly after noon, Kenkel sentenced Lund to indefinite incarceration. The sentence will be reviewed by the Parole Board of Canada in four years, as outlined in the Criminal Code.
"There will never be a time when it will be safe to release Mr. Lund into the community," Kenkel said in handing down his sentence in a Barrie courtroom.
Earlier Wednesday, Kenkel labelled Lund a dangerous offender. As that finding was read out, Lund's supporters — including his father Mark, a former Ontario Provincial Police officer — started sobbing. Mark Lund has also been charged with obstruction of justice in the case.
Shayne Lund, wearing black-framed glasses and a red-collared dress shirt, appeared to be shaking as the judge's decision was read to the court.
Kenkel said Lund shows a "complete inability to control sexual impulses," and his "conduct resulted in pain and serious harm to others."
Lund's "repetitive behaviour" from his teens to his early twenties was aggressive, Kenkel said, and showed a "complete disregard for others."
Lund displayed a "history of manipulation and deceit" that cast doubt on his prospects for rehabilitation, Kenkel said.
'He's very nervous'
Lund declined to speak in court Wednesday. His lawyer, Eginhart Ehlers, told court that Lund wanted to offer his sincere apologies to the community.
"He's declining to speak because he can't get his thoughts straight. He's very nervous, and virtually unable to focus," said Ehlers.
"He's had a tough time while incarcerated."
Ehlers argued Lund should be sentenced to eight to 10 years.
Lund has no previous criminal convictions and has spent nearly half of his time in pre-trial custody, in segregation.
"His 37-month period of time going through this process has opened his eyes to the damage he caused," Ehlers said. "The irreparable damage to his own family, his own life, more importantly to his victims, to young children, the devastation to their lives."
Ehlers told court Lund has had no contact with his family while behind bars, which has had a "severe impact" on him.
Crown prosecutor Indy Kandola called Lund a "rare-breed offender" and is pushing for an indeterminate sentence.
"He lives and breathes to violate children and animals," Kandola said Wednesday, adding Lund is an "incurable pedophile."
Girlfriends plead guilty
Lund pleaded guilty to six counts of sexual assault, as well as charges of bestiality, possessing child pornography and conspiring to administer a noxious substance to a person under 16.
The crimes involved up to 14 children, and occurred in Orillia, Penetanguishene and Waterloo, the Crown told the court.
Two of Lund's former girlfriends, Avery Taylor and Kathryn Thompson, pleaded guilty to almost a dozen charges each.
Both were sentenced to jail time and designated long-term offenders.
