Raffaella Maria Stroik was reported missing on Nov. 13 after a ranger found the car.
Around 150 people, including an air and water rescue team, joined a search for Stroik, Brown confirmed to the Dispatch.
A private plane pilot found what he thought was a body in the water. Her body was then found at 9:40 a.m local time on Nov. 14, the highway patrol said.
More details about her death will be released later in the day, officials said.
She became a dancer with the St. Louis Ballet in September 2017. “I grew up watching the 1993 version of New York City Ballet’s The Nutcracker,” she said in a video. “And so coming to St. Louis to dance with this person I had watched growing up was so exciting.”
Stroik, who is originally from the Indiana city of South Bend, was also a ballet teacher at a nearby academy.
Before her body was found, Brown said the area is remote.
“The biggest challenge is going to be it is a very secluded area,” Brown told Fox2. “Lots of timber, lots of wooded areas, mixed in with some grasslands as well. Not a lot of homes in the area to where we could have potential witnesses.”
