Investigators said Robertson had worked at the plant for about seven months.

An autopsy is scheduled for Thursday.

General Motors canceled Orion's production of Chevrolet Bolt electric vehicles on Thursday. Production will resume Friday. The automaker said in a statement it "will start the shift with a discussion about the recent incident at the plant and the support services available to employees."
