Moment Georgia bar customer 'launches unprovoked sucker punch attack on another man, killing him'

A bar customer in Georgia has been charged with murder after what authorities have described as an unprovoked sucker punch attack against another man.

Police say David Digiacomo, 40, punched 34-year-old Clint Ali early Friday morning at Jack's Bar And Grill in Braselton, killing him.

Surveillance footage obtained by Fox 5 shows a man identified as Digiacomo walking up to Ali and punching him on the side of his head. Ali was at a jukebox when he got punched, according to Braselton police.

'It's murder, I mean the guy just go up to him, a defenseless guy doesn't even know what's about to hit him,' Assistant Police Chief Lou Solis said.
