Megan McAllister, fiancée of alleged Craigslist Killer Phillip Markoff, has apparently abandoned plans to stand by her man: The faithful fiancée wasn't wearing her engagement ring when she visited Markoff in prison today. McAllister's lawyer said their August 14 wedding plans are "being dismantled" since Markoff has been charged with murdering a woman he met on Craigslist and robbing two others. McAllister, also a medical student, was with Markoff when he was arrested on April 20 by Massachusetts police. She's expressed her solidarity with her accused fiance, even as the mounting evidence against Markoff began to look bleak. "I think this was a big step for her to realize the seriousness of the charges her fiancé faces," her lawyer said.
