Jay's mum should have been able to tell if that looked like his hand in the snapchat. I think it would be out by now if she didn't think it was his hand.It’s a shame there is no CCTV or other incontrovertible proof he was there. Based on those people’s claims and the Snapchat of the steps, including a person who might or might not be Jay, I wouldn’t like to assert 100% that he was there. My opinion only, obviously.
The searchers are focusing a lot of time, energy and money on the search in the mountains. The locations they choose are based on info the police give them. That strongly suggests to me that the police do feel there's enough evidence to place him in Masca. I think they've talked to Jay's friends, talked to the BNB guys and Ofelia to make sure that the identity of the lad they took back fits with Jay. If the messages from Jay with Lucy or Brad were through Facebook, the police would ask to view them and look at the timestamps. So I really think Jay was at the BNB in Masca and was at the location north of Masca at 8.50am.
