A 61-year-old man is expected to be charged with murder in connection with the shooting death of a Chicago man nearly 40 years younger over a traffic dispute.

WGN-TV reported on Friday that the victim, 23-year-old Montrell Moss, encountered the unidentified man in nearby Hammond, Indiana, on Thursday. The man allegedly cut Moss off on the road twice, prompting Moss to respond by throwing a glass of water at the man's vehicle.

The victim's family members told WGN that the man then pulled out a 9-millimeter handgun and shot Moss. WBBM-TV reported that Moss' car then careened off the road and hit a pump at a gas station. He was later pronounced dead at a local hospital. Moss' girlfriend and their three children, who were in the car with him at the time, were not injured.

A witness later allegedly spotted the other driver and identified him to police, who reportedly found the gun and a shell casing in his vehicle before arresting him.
