Fayette County investigators are trying to figure out what caused a crash that sent 3 people to the hospital.
It happened just before noon on Muir Station Road, just north of Briar Hill Road.
One vehicle, carrying three people, was involved in the accident along the narrow road with lots of curves.
Investigators say it appears the driver lost control of the SUV and flipped.
Two people were taken to the hospital with minor injures, the third, with what appear to be life threatening injuries.
Accident reconstruction is now on the scene gathering more details.
