The Walking Dead: Is Lizzie The Real Killer?

One of the most persistent rumors to circulate over the last few months about AMC’s The Walking Dead is that Carol Peletier is serving an “exile” for crimes she didn’t commit.That is, that Lizzie–the elder of the two girls in Carol’s charge–is actually the one who killed Karen and David back at the beginning of the season, and that Carol had taken the rap for her because she’s a kid.If you head over to any Walking Dead fan forum or to Reddit, it doesn’t take long to find a number of such theories, revolving around not only her attachment to a walker early in the season but also comments made by her sister from time to time about the fact that she isn’t stable.
