A local man has been arrested for fraudulently using a credit card in a case that was recently featured in a crimestopper announcement. Damien Brock Mackey, age 24 of Boone, was charged Monday with two counts of unauthorized use of a financial transaction card.  Mackey contacted police after seeing the December 1st crimestopper story reported by local media. Mackey admitted to making the suspect transactions after finding a lost wallet containing the card. Mackey was taken before a Watauga County Magistrate where he was held under a $500 secured bond and given a February 2nd, 2012 court date.
