MURRAY COUNTY, OK -- The search continues Tuesday evening for a man authorities believed drowned in a Murray County lake Saturday.
Park rangers at the Chickasaw National Recreation Area in Sulphur say a 51-year-old man jumped off a pontoon boat into the Lake of the Arbuckles to swim around 1:30 PM Saturday afternoon and never resurfaced.
Rangers say they've been searching for the man ever since, but have not been able to locate him.
They believe he drowned in approximately 70 feet of water.
They'll say they'll keep combing the lake until they find him.
