Jay Slater, a 19-year-old British apprentice bricklayer, vanished on June 17 in Tenerife after attending a music festival.

Despite extensive searches by Spanish authorities, Slater remains missing.

His family believes third parties may be involved, rejecting the notion that he simply disappeared.

Recent developments include the discovery of sunglasses near his last known location and claims that Slater had stolen a Rolex watch.

A private detective revealed Slater declined a phone charger and a ride on the morning of his disappearance.

As official searches conclude, the family continues their desperate hunt for answers.
