How did McCartney exploit his victims?published at 15:04 British Summer Time

McCartney mainly used the social media platform Snapchat to exploit victims
Pretending to be a girl and operating mainly on Snapchat, McCartney found and befriended girls who were said to be struggling with sexuality all over the world.
He used flattery to get a compromising photograph and then used it to blackmail and threaten the children into committing appalling acts or he would publish the images online.
McCartney told one girl that he would get people to come to her house to rape her if she didn’t comply.
According to Catherine Kierans, acting head of the Public Prosecution Service’s serious crime unit, McCartney’s offending was relentless.
“You had little girls, an average age of 10-12 years old being threatened in the most depraved way," she told BBC News NI.
“It was around the clock, it was difficult to know when he was doing anything else.”
The victims spanned 30 countries; the abuse included involving other people, family pets and objects.
In one incident, it took McCartney just nine minutes to blackmail a child.

Cimarron Thomas was 12 years old when she took her own life after being abused by McCartney
The identity of the little girl who took her own life after being abused by McCartney can now be revealed as 12-year-old Cimarron Thomas.
Cimarron lived in West Virginia, USA, with her mum, dad and siblings.
She played the violin, she loved elephants and chatting with her friends on Snapchat.
They were an ordinary American family but in 2018 a predator was about to bring destruction to their lives.
Cimarron took her own life rather than comply with McCartney’s depraved demands that she include her younger sister in the abuse.
Her father, Ben, a US army veteran, killed himself 18 months later not knowing what had caused his daughter’s death.
In 2021, just before McCartney was due to be arraigned on charges, investigators discovered Cimarron’s identity and what had happened to her.
McCartney was ultimately charged with her manslaughter – a charge he pleaded guilty to earlier this year.
