Moment bar customer David Digiacomo punched victim in unprovoked attack, killing him

Braselton police say a bar customer has been charged with murder after what they described as an unprovoked sucker punch attack against another man.

According to the police report, David Digiacomo, 40, punched 34-year-old Clint Ali early Friday moing at Jack's Bar And Grill in Braselton, killing him. 

In a video recorded at a bar in Hoschton, northwest of Athens 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. 

Ali falls to the ground, and nearby patrons get up to assist him.

"Digiacomo walks back to the bar, gets his beer and starts drinking again as the ladies come to Mr. Ali's aid," said assistant Police Chief Lou Solis. "On video, you see Mr. Digiacomo come and stand over Mr. Ali with beer in hand, as if nothing happened. He then tries to justify why he hit Mr. Ali. You see at one point Mr. Digiacomo point towards his friend that says was threatened and back to Mr. Ali as to say this is why he punched him."

'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,' Solis said.

Digiacomo, according to Solis, told other people inside the bar that Ali had previously made threats against one of his friends.

But, Solis said, no report was ever filed about such threats - and it wouldn't make any difference in the case.

Ali didn't have any enemies, the bar manager said. 

Investigators at the Georgia Bureau of Investigation crime lab found that the punch and the fall that ensued had killed Ali. 

A nurse who was inside the bar at the time and paramedics who responded to the scene gave Ali CPR. He died at the hospital.

Digiacomo was charged with felony murder, aggravated assault and obstruction of justice.
