St. Tammany Parish Sheriff’s Office deputies found the body of a man floating in Lake Pontchartrain east of the Interstate 10 twin spans about 8 a.m. Tuesday as they were entering the third day of a search for a man seen jumping from the westbound bridge Sunday.

Motorists said they saw a man get out of his vehicle, a black Cadillac, and jump over the side of the bridge about 8:30 a.m. Sunday.

Deputies had been searching the eastern portion of the lake with helicopters and boats equipped with underwater imaging devices. A U.S. Coast Guard helicopter aided in the search on Sunday.

St. Tammany Parish Coroner Dr. Charles Preston identified the man Tuesday afternoon as Tam Van Nguyen, 38, of Biloxi, Mississippi.

He said Nguyen’s family positively identified the body. An autopsy will be performed Wednesday.
