John (Fallout 3)

This Wastelander is believed to be John, because of the note and key he is carrying.

He appears only as a random encounter. You will find him being attacked by 3 Vicious Dogs, he is supposed to die in this encounter so you can find what he is carrying.

Backstory
"John" seems to have stolen the books from his brother.

Common Locations

 * In front of the Super Duper Mart
 * In front of the Robot Repair Center
 * Anchorage War Memorial.
 * Alexandria Arms.
 * Outside Vault 106.
 * Outside Rockopolis

Bug
The "John" may be encountered and get killed multiple times, usually in the same spot.

For me, I found John's key and note on a random wastelander who was female and just named 'wastelander'. I found her outside the Foxtrot Echo entrance, south of Oasis.
