SULPHUR, Okla. -- Police say 29-year-old Nathan Gonzales of Pauls Valley was found about 20 feet from the shore at the end of 110 in the Chickasaw National Recreation Area.
He was swimming with a group of friends around 6:30 Sunday night when they noticed he was missing.
Park officials are not sure what caused him to go under, but they say the lake is up about 4 feet.
Last year, a man drowned in the same swimming area.
Officials are still investigating this incident.
