I just wonder why she thought she wouldn't get caught. To me it seems like writing a personal check to your dealer for heroin.
We already know she was a webcam "model" so I still say the motive was money.
Does it matter? to the victims, no, the damage is done, but what can be learned from this that will help protect children in the future?
If money was the motive, than the rehabilitation path should be treating the vice that needed to be financed, and/or vocational training.
Also, I would think a person motivated to commit a crime for money rather than the perverted desire to have sex with a child for gratification would be less likely to re-offend.
