The body of a woman was found inside a submerged car near a boat ramp at Blue Spring State Park in Volusia County, deputies said Wednesday.
The woman has been identified as Kathy Marie Hilbert, 57, of Daytona Beach.
An out-of-town relative had requested a well-being check on Hilbert on Jan. 5.
Daytona Beach police responded and ultimately put out a countywide alert to be on the lookout for Hilbert when she wasn't located.
Investigators don't suspect foul play in Hilbert's death. The official cause and manner of death will be determined by the medical examiner.
A kayaker, Scot Leins, found the car Wednesday morning in the St. Johns River shortly after he placed his kayak into the water.
"We were out there paddling and we came across this car that was in the water, and I called for help," Leins said.
