An 80-year-old woman who died after being found unconscious in a restroom at an eastern Georgia McDonald's was killed by a lethal dose of carbon dioxide, authorities said Wednesday.
An investigation determined that a "bleed line" on the tank used to carbonate beverages in the McDonald's drink dispenser was "improperly disconnected within the wall cavity," Pooler, Georgia, Police Chief Mark Revenew said.
This caused carbon dioxide to build up in the restroom, which was in close proximity to the tank, "in a potentially lethal concentration," he said.
