Post-dead canoeist found on Google Pics

How did they trip up the Hartlepool canoeist who paddled out to sea five years ago, leaving his widow with life insurance money, only to surface this week in a London police station claiming amnesia? A snapshot of John Darwin and his wife in their new Panamanian condo, confronted with which his wife confessed “well it explains a lot, doesn’t it?”
 
How the photo came to light is an inspiration to all amateur internet sleuths. An ordinary UK housewife googled John and Anne in Panama. Google Images came p with the picture on the real estate website of their Panamanian broker. Try this at home!
