The discovery comes amid a search for Kori Gauthier, 18, an LSU student from Opelousas who has been missing since Wednesday. Her car was found on the Interstate 10 Mississippi River bridge in Baton Rouge last Wednesday.

LSU police were in contact with St. John the Baptist authorities, but LSU spokesman Ernie Ballard III said nothing had been confirmed.

Gauthier's car was found in a salvage yard Wednesday after it had been wrecked on the bridge early last Wednesday. Officials said Gauthier wasn't in the car when it was struck, but her wallet and cell phone were inside.

News of the body found Tuesday in Reserve came less than a month after another deceased woman was found in the river in nearby St. James Parish. Police identified the body in that case as Raemel Richardson, 31, whose boyfriend allegedly shot her to death somewhere in the Baton Rouge area, then dumped her in the river.
