The guilty plea was part of a deal to drop a manslaughter charge.
“The manslaughter charge was dropped with full knowledge and approval of the victim’s family,” said 24th District Assistant Attorney Ray Hardy.
Starr was sentenced to 10 years in prison probated for the lesser charge.
Starr, in September 2012, was overcome with road rage after he had a problem with a tractor-trailer rig. He cut in front of the rig and stopped in front of the rig about two miles north of Refugio on U.S. Highway 77.
The tractor-trailer driven by Firas Walid Hmeidan applied brakes and Leon Dale Buff, who was following behind the rig, slammed into the trailer. The collision killed Buff.
Starr fled the scene but was later located.
Starr and Hmeidan were not injured in the fatality.
“One unique thing about the probation is the conditions,” Hardy said.
Hardy said Starr was required to spend 30 minutes with a sign that says he caused the death of a man because of road rage at the site of the fatality every anniversary of the death during his probation.
