James Frazier helped create the conventions back in 2013 but began hitting major financial problems last year as the "Walking Dead" tanked in popularity and he began facing cash-flow problems.
According to a post on the Walker Stalker Facebook page, Frazier is now trying to unload the Walker Stalker company to investors while maintaining the Fan Fest portion.
He has frozen sales for the two Walker Stalker conventions scheduled for 2020.
But he plans to keep Fan Fest, which is is marketed as a broader science-fiction convention.
Fandemic, a rival convention company, this week on its Facebook page announced it is planning an Atlanta Walking Dead-themed convention. It didn’t offer details.
