Police say manager Robert Kuentz and a salesman got into a confrontation Friday morning at the pre-owned car sales office of Mac Haik, and the 30-year-old was shot in the neck.
Kuentz, of Spring, was taken to the trauma center at Memorial Hermann Hospital, where he died on Monday.
The salesman, identified as Keith Edward Grimmett, 49, fled the scene in a car.
Employees who witnessed the whole thing left the dealership in a state of shock after being interviewed by police.
Several hours later, police left the dealership in a hurry. We're told Grimmett made a call to turn himself in and followed through.
According to court documents, Grimmett was upset about a meeting that had taken place to the day before the shooting. He reportedly confronted Kuentz to inform him that he wasn't happy about the way he was treated at that meeting.
Grimmett was arrested Friday on one count of aggravated assault, but Houston police say Tuesday an upgraded charge of murder is pending against him.
