It's a crime that has no borders.

Carly thought she was talking to her dream boy, 20-year-old guitarist Brendan Kane.Carly's mother Sonya had no idea her daughter was in such peril."She thought he was very good looking. He was a guitarist in a band in Melbourne. In Carly's eyes, I guess, the perfect boyfriend," Sonya said.

"He went to considerable lengths to manipulate her and deceive her and basically lured her with the promise of love."After months of grooming Carly, Newman concocted an elaborate plan to see her. He had created a second profile, Brandon's dad 'Shane', and offered to drop off birthday presents to her house in Adelaide.

Carly was driven from her home to a beach in Adelaide. When she rejected Newman's sexual advances she was brutally murdered before being thrown into the ocean. Today, Newman begins 29 years behind bars.Carly Ryan's mother Sonya released a statement saying she was relieved the community now knew the truth."I am relieved that Garry Newman is no longer a danger to the community and other innocent children," she said.

"I am pleased that the truth has been revealed for Carly and the community can now see the enormous level of manipulation and cruelty carried out by this man."Bernadette McMenamin is Chief Executive of child protection support group Child Wise."We get ten calls a day. Stranger danger doesn't exist because kids add these people as 'friends', so you have sex offenders in you home," Bernadette said.
