The Sun-Sentinel reports that Byrne, 41, had cut off a driver while driving on Interstate 495 in Davie, Florida on June 7.

Police say that Byrne pulled over at the next stop light intending to apologize for cutting off the blue BMW sedan. Instead, Andre Sinclair, who was a passenger in the car being driven by his girlfriend, exited the vehicle, approached Byrne who was still in his truck, and shot him in the chest.

Byrne returned fire on Sinclair, shooting him twice. Byrne died on the scene and Sinclair died two days later in the hospital.

Both Byrne and Sinclar had concealed carry gun permits.

During a press briefing on Wednesday, Davie County Police Sgt. Mark Leone called the entire incident ultimately “pointless and silly.”

Sgt. Leone said that at the time of the shooting, Byrne was on the phone with a friend, who later told police he heard Keith say “My bad” while on the phone “in making an attempt to apologize.”

“At that time over the phone he heard the gunshots and Mr. Byrne said, ‘I think I’ve been shot,’ started slurring his speech, and then the phone call was disconnected.”

Sgt. Leone said: “Mr. Byrne was acting in self-defense when he ultimately fired back at Mr. Sinclair,” and added that if Sinclair had survived, “we would have identified him as the primary aggressor, and he would have ultimately been charged with murder.”
