I'm not sure if anyones addressed this or not. When the Governor was spouting off a list of the dead to Andrea, he names 7 people. The 3 killed in episode 6 (Gargulio, Crowly, Tim), Eisenburg, Bob Adams, Haley (arrow girl), and Richard (guy killed by Walkers in the town). We know Warren was killed by Maggie with a bone to the throat and Rick killed a guy that he thought was Shane. So I assume Warren's last name is Eisenburg and the Shane dopple-ganger would be Bob Adams. I'm guessing that everyone else who was shot during episode 8 were just wounded and didn't die. Thought that might be a decent deduction to updating the wiki.
