Something struck me, though. The timeline...I need some clarity on it and perhaps you awesome sleuths can help.
TH was (allegedly) spotted by Chas along this route, he says between 09h15 and 09h45 on June 4th. But we know that she posted the Science Fair pics on FB at approx 09h00 (is that right??)
So, easy to leave the school at, say, 08h45 and then drive home, put the pics up, and be at Logie Trail by (round it off) 09h30. BUT - where was Kyron all that time? Where was Kyron in between 08h45 and 09h15?
After the revelations about TH, I can't assume to put anything past her. I just wonder what the heck she did with Kyron in between these times. I think I'll go and see if I can find a screenshot of her FB account somewhere to ascertain what time she posted the pics on FB.
