I think you are right Humdinger, it was that day according to this article.
However, having said that, so many things slot into place when considering that Gary may have suffered drug-induced psychosis. His mum and Anika hanging onto hope that he may still be out there somewhere, the odd behaviours, his dad being peeved and 'never going back there', as if they knew he may have a problem sometimes when taking certain types of drugs (legal and illegal). The family never using that word 'accident'. The urgency of that huge search .. if they could only find him soon enough, he could be okay .. and still his mum and Anika did not give up hope.
When Derryn Hunch said that psychosis can and does creep up on a person, often when they are 'coming down', it finally started making a little sense to me.
Still - need to wait and see what the November inquest brings.
