A woman has been arrested in the US on suspicion of posing as a registered nurse.
A police investigation was launched after hospital bosses terminated Autumn Bardisa's contract due to concerns about her qualifications.
Investigators found the 29-year-old had provided medical services to 4,486 patients between June 2024 and January 2025.
"This is one of the most disturbing cases of medical fraud we've ever investigated," Flagler County Sheriff Rick Staly said.
Bardisa was employed by AdventHealth Palm Coast Parkway in Palm Coast from July 2023 to January 2025.
