Twenty-one-month-old Ben Needham disappeared near his grandparents' farmhouse on the Greek island of Kos. His family had been renovating the property, and the child vanished during a brief period when relatives believed another adult was watching him.
Greek and British investigators pursued reported sightings and abduction theories for decades. Later inquiries examined whether Ben might have died in an accident involving construction machinery near the property, but searches did not recover conclusive physical evidence.
Ben has never been found, and no account of his disappearance has been proven. The case remains unsolved.
