Man, Memphis is hot these days! go tow WMC-TV link for a railroad bridge that caught fire story.
Also heard that this woman confessed to selling DL's through one of the men arrested "5 or 6 times" before. Which probably means 20 or 30 times. So there are literally hundreds of potential terrorists with valid Tennessee DL's running around.
IMO she was killed to prevent her from giving out any of these names.
