Two men were killed Wednesday night, crushed by an unmanned forklift while working inside a truck at a Dallas plastics company.
Dallas Fire-Rescue spokesman Jason Evans said the forklift rolled into the men as they were working with a load at the back of the truck.
The men were identified by the Dallas County medical examiner's office as 59-year-old Jimmie O'Farrell and 51-year-old Robert Berg.
Evans said he had no information on what may have caused the forklift to roll into the men, but that investigators with the Occupational Safety and Health Administration would be looking into the incident.
The medical examiner has not ruled an official cause of death for either of the men.
