Political Whodunit Puts Spotlight on Williamson County

WASHINGTON (AP/WMOT) — A political whodunit has the national media focused on Williamson County.

The Secret Service was in Franklin Thursday investigating claims that someone burglarized a PricewaterhouseCoopers accounting office there and stole two decades' worth of presidential candidate Mitt Romney's tax returns.

Authorities are studying computer thumb drives that were delivered with an unusual demand: a $1 million payment in hard-to-trace "Bitcoin" internet currency.

The plot in this mystery could be a hoax, but it surfaces at a critical moment during the 2012 presidential campaign.
