Detective who solved McCann case searches for missing teenager

The investigator who examined the disappearance of Madeleine McCann was spotted in front of the house where missing Jay Slater was last seen. Former detective Mark Williams-Thomas has joined the search for the British teenager who went missing in Tenerife on Monday, June 17.

Mark Williams-Thomas, who investigated the Madeleine McCann case, has joined the search for the teenager from the United Kingdom. According to "The Sun," he was photographed leaving a meeting with the distraught family of missing Jay Slater.

Jay went missing in Tenerife on Monday, June 17. Although a search operation is underway, rescue teams have so far been unable to trace his whereabouts. The detective announced that he would obtain answers and additional information for the 19-year-old's family within three days.

"I don't want to talk in detail at the moment, but I've spent time with the family and my focus now is to build a clear timeline of the last 24 hours before Jay disappeared", said detective Mark Williams-Thomas.

Mark first contacted Jay's mother, Debbie Duncan, last week to offer her his help. The investigator has examined several high-profile missing persons cases, including Madeleine McCann's disappearance.

"I would quickly be able to do establish whether or not there are suspicious circumstances - but I'd need total access to everything and to speak to all the witnesses involved", assures the investigator.

The search involves the authorities, the private detective, and friends of the missing Jay.

Detective Mark Williams-Thomas assures that he will contact the two Britons with whom the 19-year-old left a music festival. It is known that the boy went with them to Masca in the north of the island. Jay stayed in a rented house with them for a few hours before trying to return to his holiday apartment.

Last Monday morning, he made his final frantic call to his friend Lucy Law. Jay told her he was lost in the wilderness, without water, and had only one percent battery on his phone.

Search efforts have utilized tracking dogs, drones, helicopters, and dozens of search and rescue teams. "The Sun" revealed that British police have not interviewed the two men Jay was with before he disappeared. They were only questioned by the local police.
