Leslie Cox (3752)

6/2/2007: A special deputy fired his gun while trying to break up a lakeside crowd, fatally shot Cox in the head, and maintained that he'd been justified. Many witnesses disputed his story and there were suggestions of a personal grudge. The shooter was charged with manslaughter, one of the rare cases with an officer indicted for a line-of-duty killing. After much legal maneuvering the shooter was acquitted in 2010. http://www.wkyt.com/home/headlines/10210856.html
