An 80-year-old woman has died after being sickened by fumes at a McDonald's restaurant in south Georgia.

Pooler Police Chief Mark Revenew says Anne Felton of Ponte Vedra, Fla., died early Thursday. She and her husband were customers at the restaurant. An autopsy will be conducted to determine her cause of death.

Felton was one of 10 taken to the hospital Wednesday after firefighters found two customers unconscious in the bathroom and others struggling to breathe.

Authorities suspect cleaning chemicals in the restroom are to blame, but the cause is still under investigation.

McDonald's said in a statement Wednesday that the restaurant reopened after authorities deemed it safe. The company did not immediately comment on Felton's death.
