The Florida Highway Patrol says four people died in a wrong-way crash on I-95 in Martin County.
Investigators say Carolyn Ramos of Port Saint Lucie was driving southbound in the northbound lanes of the highway early Sunday when she slammed her Jeep into a Chevy pick-up truck in Palm City.
WPTV reports the vehicles became stuck together and caught fire.
A witness pulled Ramos from the wreckage. She was taken to Lawnwood Medical Center in critical condition.
The FHP is investigating whether she traveled the wrong way from St. Lucie to Martin County. They are also investigating whether she was drinking while driving.
The victims in the pickup truck have not been identified.
