Police say Jermaine Green was speeding and tailgating other drivers.
The suspect is described as a white male in his 50s with a long, gray goatee.
After flashing his headlights at another driver to get them to change lanes, the Camaro driver then pulled alongside that car and pointed a semi-automatic pistol at the driver.
It happened Sunday at the intersection of Sashabaw and Clarkston road in Clarkston.
Martin Zale was told that his fatal encounter with Derek Flemming was a “shooting waiting to happen” and that Zale went about “almost looking for conflict.”
A 69-year-old man who insists he shot another driver in self-defense is back in court to be sentenced for second-degree murder.
Martin Zale claimed he shot Derek Flemming in self-defense last September during a confrontation at a stop-light.
A jury returned a guilty verdict for a 69-year-old man charged with murder in the fatal shooting of a motorist during a road rage incident in Howell.
Martin Zale took the stand in his own defense earlier in the day. The case in Livingston County Circuit Court went to the jury Tuesday afternoon.
Prosecutors say Flemming, 43, was shot in the head in Sept. 2 after getting out of his vehicle to ask Zale about his aggressive driving.
