A woman's body was found in a van partially submerged in the reservoir at Jacobson Park on Thursday morning.
Authorities identified her as Cheryl Carter, 48, of Lexington. The vehicle, a 1994 Chevrolet Astro van with Tennessee plates, was recovered, and an autopsy has been scheduled for Friday.
Fayette County Coroner Gary Ginn said the death is being investigated as an accident, but other possibilities as to how Carter died are not being ruled out.
Carter's ex-husband, Mark Carter of Bowling Green, said she had suffered from lupus and other ailments, which had left her unable to work since the early 1990s.
He said that anything he would have to say about his former wife's death would be speculation, but that he was concerned about something their son told him after they heard about the death.
"He made the point that she doesn't drive anywhere anymore. I don't know, it just kind of sounded kind of funny to me," Mark Carter said.
The investigation into Cheryl Carter's death began around 9:25 a.m. when police received a call of a submerged vehicle near the park's paddle boat rental area, said Lexington police Lt. Ron Compton.
Compton said two fishermen saw the top of the vehicle sticking out of the water, which was about 4 or 5 feet deep.
Ginn said it appeared that the van had been driven from a concrete boat ramp into the water.
"The vehicle was locked. The key was in the on position. The gearshift was in the drive position," he said.
"I don't think she'd been there very long — probably hours," he added.
The coroner said there were no obvious injuries to the body. He said old medication was found inside the vehicle and that toxicology tests would be performed on the body.
Mark Carter said his ex-wife worked for GTE in Lexington at one time. She also worked as a dental assistant for a while, he said.
In the early 1980s, the Carters had a daughter, Amber Dawn, who was stillborn, Mark Carter said, adding that his ex-wife had said that when she died she wanted her ashes spread over the baby's grave in Fairview Cemetery in Bowling Green. The Carters' son, Jeremy, who is 32, lives in Bowling Green.
The couple divorced 13 years ago after about 20 years of marriage. Mark Carter said his former wife was living with another man in Lexington at the time of her death.
She was born and reared in Evansville, Ind. She and her family moved to Lexington from Bowling Green in 1983.
Mark Carter said his ex-wife occasionally visited Bowling Green to attend her grandchildren's school functions and about a month ago was looking for an apartment there.
She had two grandchildren and two step-grandchildren, he said.
