Google Earth Community is a collection of Google Earth users who post Google Earth images of interesting places on the planet. They also post historical maps and images and links to particular locations as they're seen today.
And what do you know, some murder fanciers have tagged historical sites of interest under the category of History Illustrated, so you can do some true crime travel or even investigation from your desktop. There are thousands of images tagged, but let's narrow it to some of our favorite subjects --
The John Sowden House, Los Angles - Where Steve Hodel says his father murdered Elizabeth Short.
A Jack the Ripper site (one of many)
Bodom murder scene - Finland's most infamous case of all time.
Evelyn Dick, Canada's Torso Case - a beautiful woman, a bizarre murder
and so on.
and my favorite... what grows in the Garden at the Edgar Allan Poe Museum?
