I agree, MU, I don't think we can assume age. He may have been young (look at what Derek Percy was up to, age 21.. and younger) or he may well have been an older man. I hate that this horrible crime went unsolved, too... and there's women out there, with kids, who perhaps have known or even married a man like that. Let alone all the victims he could have accrued. Sickening, for sure.
Just a thought on her being fully clothed... though he dumped her like trash. I think this again (with the way she was dumped, so close to the gutter) indicates he had her in a vehicle - if anyone looked in they'd see a 'sleeping' child, not a naked one. In any case, he took the time to do that, but left her in the gutter and not in the large reserve just metres up the street from where she lay, with lots of places to conceal her there behind buildings and trees, etc. So I reckon he got a fright and panicked. Maybe a cop car went by....
I wish I had less than a million things to do this week. I want to search for that previous attack. And for other possible perps who used a "photographer" ruse.... though here's what bothers me about that:
The "photographer" was trawling for kids, hoping to find a mother naive enough to hand him hers, and this makes me doubt he was a full-on local - there's a huge chance he'd be recognised later if he lived in the area. He'd have to have stalked the family pretty closely though, to catch that one moment days later when Kylie was alone and vulnerable. He might have been that fixated on Kylie - but IMO it's more likely, from his behaviour, that Kylie's killer was living or staying locally and he snatched her from sheer opportunity.
I think it's worth looking for "photographers" anyway. Just cause I think something's likely, doesn't mean it happened that way. I think time might have allowed this killer to reveal more of himself via other crimes, other attempts.. no way did he stop with Kylie. He's out there somewhere, and sadly so are the rest of his victims.
