winn and scheuermann rolled out through the flooded streets.near the superdome, they spotted three water trucks. they said a man near one of the trucks had a gun. both officers took aim. these pictures show dwayne scheuermann at the scene. ( gunshots ) they hit the man in the torso-- but he survived. his name was keenon mccann. and when the cops apprehended him there was no gun to be found. the police theorized he might have thrown it away-- off the overpass. keenon mccann was lucky that day. he survived getting shot. he's since died, but his brother and sister-in-law were with him on the bridge. they say he didn't have a gun. that he was stranded there with his family. what do you think happened? >> what i think happened, that i think they just came out there and got the wrong people, or the wrong person. mistakenly shot keenon for nothing. that's what happened. if he had a gun, why did they bring him in baton rouge to the hospital? brought him there, un-handcuffed, he stayed there for a minute, and then they cut him loose, and let him go free
