1 person dead after fight at GM’s Orion Assembly plant: How he died

A 49-year-old man is dead following a fight at General Motors’ Orion Assembly plant in Orion Township, the Oakland County Sheriff’s Office confirmed Thursday in a news release.

Sheriff’s Communications Officer Steve Huber identified the victim as Gregory Lanier Robertson of Pontiac. Robertson had worked at the plant for about seven months. A 48-year-old male coworker was in custody at Oakland County Jail.

Later Thursday afternoon, the Oakland County Medical Examiner’s office completed the autopsy report. It lists Robertson’s death as homicide with the cause as “multiple blunt force injuries,” Cas Miarka, an administrator at the medical examiner’s office, told the Free Press. 

General Motors Orion Assembly is seen on October 25, 2019.

The sheriff’s office confirmed both men in the fight worked for a cleaning service hired by GM, but Huber told the Free Press his office is not releasing the name of that cleaning company. GM hires vendors to do cleaning as well as some maintenance and parts distribution for the assembly line.

The plant was shut down Thursday for the investigation, but regular production will resume Friday morning and employees should report at their regular time unless notified otherwise by their leaders, GM spokesman Dan Flores said.

“We will start the shift with a discussion about the recent incident at the plant and the support services available to employees,” Flores said in a statement.

Dead at the scene

Huber said earlier Thursday that “there was an altercation and we have detectives on the scene. It happened at 1:37 in the morning and there was no risk to the public.”

Huber later described what happened in a news release:

Deputies arrived to find Robertson “unconscious and bleeding.” CPR was performed but deputies could not revive him. He was pronounced dead at the scene. 

The suspect was found in a dock area not far from Robertson’s body. “The item used in the slaying was recovered,” Huber said in the release. “The incident and possible motive remain under investigation.”

In a statement released later Thursday, Flores said GM was working with the Oakland County Sheriff’s Office to investigate “an altercation between two employees of a third-party service provider at Orion Assembly early Thursday morning. The incident resulted in the death of one of the individuals. Our thoughts and prayers go out to the victim’s family.”
