Witnesses described Slater as being 'on a mission' after taking a cocktail of drugs on the night he vanished

Celebrity detective Mark Williams-Thomas claims to have uncovered explosive new evidence suggesting Jay Slater armed himself with two knives and stole a bag of ketamine before his disappearance in Tenerife last June.

The investigator's months-long probe has revealed witness statements from key figures who couldn't be traced for the recent inquest, including the last person to see the 19-year-old alive.


According to the investigation, detailed in a forthcoming two-part podcast, witnesses described Slater as being "on a mission" after taking a cocktail of drugs on the night he vanished following a music festival.

Williams-Thomas managed to track down Ayub Qassim, the convicted drug dealer who accompanied Slater back to an Airbnb, just weeks after the coroner expressed frustration that police couldn't locate him.

In the podcast, Qassim revealed: "One of your mates, yesterday walked way because he's f**ked off with the ket [ketamine] and he went missing."

Lucy Law, who also didn't attend the inquest, told Williams-Thomas that Slater said he was "on a mission", couldn't "go back to the rental" and had "taken two kitchen knives down his pants in case anything kicks off."

Both witnesses' statements provide crucial context missing from the official investigation.

Williams-Thomas believes the ketamine theft explains why Slater armed himself and couldn't return to his accommodation.

"If Jay did take Qassim's ketamine this would explain why he put two knives in his waist band for his own protection and why very significantly he said to Lucy he couldn't go back there," the investigator says in the podcast.

The detective added: "This evidence gives rise to a reasonable belief that Jay was scared or worried and that's why he had the knives in his waistband."

Williams-Thomas said his intelligence indicates the rental location was "specifically chosen so as not to bring attention to any illegal activity."

Slater, an apprentice bricklayer from Oswaldtwistle, was found dead a month after his disappearance with severe head injuries at the bottom of a remote ravine.

Williams-Thomas concluded: "Jay was heavily under the influence of drink and drugs, and in his own words 'on a mission' met up with a convicted drugs dealer who from the evidence I have seen remains heavily involved in the supply scene."

He added: "Having done a thorough investigation and spoken to witnesses the conclusion is that Jay's death is a tragic accident with no third party involvement."

The investigator has shared his findings with Jay's mother Debbie, whom he describes as "heartbroken".
