On a Thursday morning in March 2002, John Darwin paddled his red kayak out into the North Sea never to be seen again. Well, that is until Saturday afternoon when he strolled into London's West End police station and told the desk sergeant, "I think I am a missing person."

The father of two gave only his name, date of birth and address and told the police he had no idea where he had been since disappearing five years ago.

Officials were desperately trying to contact his wife, Anne, who reportedly moved to Panama City recently after selling their home.

It has yet to be established whether a life insurance policy payment was paid out after Darwin disappeared.
