Vile Darren Gibson, 54, was found guilty after a trial of multiple counts of abusing three young girls between 2002 and 2008.
His adopted sibling, Rebecca Kirton, was also found guilty of abusing one of the girls with Gibson.
The pair were jailed for a combined total of 36 years at Leeds Crown Court today.
Judge Mushtaq Khokhar told Darren Gibson: “You thought of nothing else but your sexual gratification. The fact it would impact badly upon them did not wrestle with your conscience.
“You betrayed those who placed trust in you. You have damaged the lives of three individuals. Their innocence was taken away at a very young age.”
Prosecutor Rukhshanda Hussain said that the first victim, who was just 10, was invited to sit in his DJ booth where he would touch her legs. She was later invited to their home for a “girly night” by Kirton.
While at their home, Rebecca Kirton placed the girl on Darren Gibson’s knee, and put a blanket over the pair. Darren Gibson then sexually touched the girl and encouraged her to do the same.
Darren Gibson persisted in his torture of the girl throughout the next years, culminating in her rape when she was 13. The court was informed that it occurred on multiple occasions, with Kirton also participating.
The girl was excessively fearful to speak and worried she would not be taken seriously. At the age of 16, she ultimately confronted Darren Gibson and declined to endure any further abuse.
The second victim, aged 14, was invited to Darren Gibson’s residence after he encountered the child at a dance where he was performing as a DJ. He intoxicated her prior to committing rape.
She was so distressed that she subsequently attempted to overdose. The DNA of Darren Gibson was subsequently discovered on the girl.
The final victim, another 14-year-old, had been attending a disco when she requested a song from Darren Gibson. He dragged her behind a curtain out of sight and kissed her on the neck. She was so shocked she ran back home crying to tell her parents.
Darren Gibson, 54, of Holdforth Close, New Wortley, was found guilty after a trial in September of 19 offences, including six counts of indecent assault, five counts of rape, five of assault by penetration, two of causing or inciting a child into sexual activity and one of sexual assault.
Darren Gibson has previous convictions for violence and has served custodial sentences.
Rebecca Kirton, 39, of the same address, was found guilty of two counts of assault by penetration, one of rape and one of causing or inciting a child into sexual activity. She has no previous convictions.
Mitigating for Darren Gibson, Robert Wyn-Jones conceded he had little to say due to his denials, but said he had not sexually offended in 16 years or had not been caught. He said he was adopted as a child which “had an impact on him growing up”.
For 39-year-old Rebecca Kirton, Nicholas Hammond said she too was taken into care at a young age and did “not have a good start in life”.
Both defendants appeared in court via video link for sentencing, with Darren Gibson at HMP Doncaster and Rebecca Kirton from HMP New Hall.
Darren Gibson was handed a 24-year jail sentence, with Rebecca Kirton being handed 12 years. Both were placed on the sex offender register for life and given sexual harm prevention orders (SHPO).
Speaking after the sentencing, Detective Inspector Stephen King, of West Yorkshire Police’s Major Investigation Review Team said: “Firstly, I would like to thank the victims in this case for their courage and bravery in coming forward.
“They have had to wait a long time to see justice finally being done and I hope today’s outcome will bring some comfort to them.
“I’m pleased that in handing down these sentences, the court has recognised the gravity of Darren Gibson and Rebecca Kirton’s offending. They are calculated sexual predators who carried out serious harm to young girls over a significant period of time.
“West Yorkshire Police has experience in investigating recent and non-recent sexual offences, we have dedicated teams across the force who are committed to investigating these offences and I would urge anyone who has been a victim of this kind of offending to come forward and report it to us.
“You will be believed, you will be safeguarded and it will be investigated.”
