The 23-year-old son of a jailed West Australian pedophile has himself received a lengthy sentence for sexually abusing girls as young as 18 months and recording the crime.
Ryan Anthony Pendleton was sentenced to a maximum nine years and eight months jail today, with a minimum seven years and eight months before he is eligible for parole.
Pendleton, who was caught with more than 50,000 images and videos depicting serious child pornography and bestiality, pleaded guilty in the WA District Court to numerous charges of child sexual abuse and downloading child pornography.
They included 20 counts of indecent dealing, 22 counts of indecently recording the abuse, four counts of possessing child pornography, two counts of encouraging a child to engage in sexual activity and one count of sexual penetration.
He also pleaded guilty to possessing obscene articles and the unlawful possession of a laptop, whose discovery led to the detection of the child abuse.
The Perth court was told Pendleton's father, Mark Pendleton, a former pre-primary schoolteacher, was serving a 16-year sentence for abusing and indecently recording 11 girls between 1995 and 2000.
Police discovered the evidence of some of the sexual abuse by Ryan Pendleton in the videos and images he had downloaded.
They found more after a search of his house uncovered hard drives and thumb drives containing the material.
Prosecutor Genevieve Cleary called on Judge Catherine O'Brien to look at the higher end of the penalties available for such offences.
"The child pornography offences ... the child abuse squad have said some of these images are the worst they have seen," Ms Cleary said.
The court was told Pendleton was in a position of trust and had unsupervised access to three girls, aged between 18 months and five years, between November 2007 and October 2008.
Ms Cleary said Pendleton had filmed himself abusing the youngest child while she slept in her cot and groomed one by feeding her lollies and then using a lolly to get her to touch his genitals.
Judge O'Brien said Pendleton had grown into adulthood with "no moral compass" and felt rejected by his parents who were unable to cope with his behavioural problems.
He went to live with his mother when his father was jailed.
He had felt unwanted after entering foster care in his teenage years, Judge O'Brien said.
Pendleton had various fetishes including a fondness for wearing women's clothing and nappies and his offending mirrored that of his father's, she said.
Judge O'Brien said Pendleton's offending was "particularly perverse and debauched" and was not isolated.
She said "three defenceless, innocent children" had been subjected to the highest category of perversion and debauchery, as Pendleton viewed the images for his own sexual gratification.
Pendleton was in a high risk category of reoffending, with a four in 10 chance of re-offending in a 10-year period, Judge O'Brien said.
She said he had lacked insight into the effects of his offending on his victims and had exploited them.
Using a lolly to lure his victim into touching his penis was an example of how prepared he was to take advantage of the youth of the child, Judge O'Brien said.
Pendleton was sentenced to six years for sexually penetrating one of the girls, 20 months imprisonment for each count of possessing child pornography and two years on each count of indecently dealing and recording the girls, to be served concurrently.
He was fined $3,000 on each count of possessing obscene articles and given a three month term of imprisonment for unlawful possession of the laptop.
The sentence was backdated to November 28 last year.
