It’s every parent’s worst nightmare.
Now Ryan has spoken about the night she came across that harrowing scene.
“I walked past Carly’s bedroom and he was lying on her bed on top of the covers and I immediately went … ‘Oh God, why is he in there?’,” she told Sunday Night.
“I just woke them up and said to him, ‘You need to get out of my house. You need to get your things, you need to get out’.”
The man in Carly’s bed was 50-year-old Garry Francis Newman. Carly met Newman online while he was pretending to be an 18-year-old musician from Melbourne named ‘Brandon Kane’. She was just 14 years old at the time.
Over several months Carly chatted intensely with Newman as he slowly groomed her from his Melbourne home.
He then flew from Melbourne to Adelaide to visit Carly and her mum under the guise of being Brandon Kane's father 'Shane'.
Newman told the young girl and her mother he was dropping off some birthday presents for her. When he told them he didn't have a hotel room booked, Sonya invited him to stay the night.
Later that night she found Newman in Carly's bed. She immediately kicked him out of the house.
But several weeks later, unbeknownst to Sonya, Newman travelled back to Melbourne and lured 15-year-old Carly to a remote beach.
Carly thought she was finally going to meet 18-year-old Brandon, but when she arrived at the beach she was greeted by Newman.
In an act of revenge, Newman bashed the Adelaide schoolgirl until she was unconscious, pushed her face into the sand to suffocate her, and then threw her into the water to drown.
