Speaking before the family accepted his help, Mr Williams-Thomas had said he believes he can get answers for Jay's family within just three days. And he also vowed to "track down" the two British men that Jay is said to have stayed with at a holiday rental the night before he vanished. He had said: "Having feet on the ground and looking at the scenario and circumstances, I know I will get to the bottom of this in three days.
Speaking on Sunday, Mr Williams-Thomas had added: "It's a week on now - I need to get on the ground and get them answers. It's about finding Jay. I come with credibility, will work with them and Spanish police, and get them the answers they need. We need to establish what the involvement is with these two guys [he stayed with], why he went back to the Airbnb and then why just leave? The chances of him wandering off are possible, but is there more to this?".
Experienced investigator Mark Williams-Thomas, who has been involved in a number of high-profile missing persons cases, was spotted yesterday close to the holiday rental where Jay Slater went missing in Tenerife
