Maybe FM had used the camera on the phone for photographing the children ... before purchasing the Bali camera.
JMO – FF speaks about the phone as if he is aware of the FM’s possible use of an internet card!:-
“To deepen the mystery, the detectives told the foster father that the phone 'didn't show any usage, any call charge records or anything. It didn't have any activations on it but it was a phone that you had and it's had a disconnection'.
'I wonder whether than might have been (the foster mother's) what do you call it, you know the internet cards ... no idea.'
Detective: 'So ... that phone there ... is the only phone'.
Foster father: "Yep, yep ... that's bizarre. It's Telstra too ... no idea.'
