Etymology of 'Murder Kroger'

Why, specifically, is it called that?

Several of my Facebook friends are members of a "Murder Kroger" fan group; the marketing-unfriendly unofficial nickname for the Kroger on Ponce DeLeon Avenue next to City Hall East.

I've heard people refer that Kroger as "Murder Kroger" since I moved to Atlanta in 1997, but cannot recall any notable violent crimes at the store.

Does anyone here know the origin of the name? Is it called "Murder Kroger" because of a specific crime? Is the name a grim comic riff on Buckhead's so-called Disco Kroger?

Anyone?
