IMHO, the money's a red herring. It can ALWAYS be traced. Always. Anybody with the cajones and skill to do what these folks have done would surely know that. I see it as yet another case of the perps playing to the profilers (or perhaps other LE misinformation/code that we don't know about).
Heard on MSNBC that a sniper magazine at the liquor store which was robbed (Alabama) had a fingerprint.
They also said that the police connected the two by a tip. I thought it has been reported that the connection was made through the credit card (stolen at the robbery, and sniper asked money to be put into that cc account).
Caprice spotted on I70.
