I've just watched the Today show clip that was put up ( Thank you BTW) .......after hearing the interview with a mum in the street, it sounds like the street is full of kids playing in front yards. Just a random thought, but...if there is usually lots of kids around, maybe not with a lot of supervision ( not a dig at any mums at all, just observation) it's not too hard to imagine that creeps may be lurking and waiting for a good moment to pounce. Maybe ,just maybe, it was a split second snatch by a random creep, who'd been staking the area for ages. The fact that it was a weekday morning doesn't fit so well with my theory....but the mum interviewed made it sound like the street was filled with playing kids usually.......also the comment about evidence being looked at was very interesting I thought.
I don't know how that poor poor family is coping. I can't believe that theres still no answers.
