A trio of Georgia cops tased and handcuffed a manâthen realized they had the wrong guy. Patrick Mumford, 24, was sitting in a driveway the afternoon of Feb. 1 when officers with the Savannah-Chatham Metropolitan Police Department approached him. Less than a minute later, they shot him twice with a stun gun. The police had a warrant for another man, Michael Clay, but immediately assumed they had their guy. Indeed, the lawmen believed Mumford was Clay, and that he was lying about his identity, a review of body camera footage shows.
