A body found in the Potomac River near the Kennedy Center over the weekend has been identified as that of the driver of a car that was swept into Broad Branch in Rock Creek Park during a violent thunderstorm the night of June 28, District police reported.

They said the man, Xavier Litchecon, 34, of 2524 17th St. NW, a driver for the ambassador of Senegal, drowned after apparently scrambling from the car as the stream was turned quickly into a raging torrent by heavy rains.

On the night of the storm, Litchecon had dropped off the ambassador about 9 o'clock at the embassy's residence at 4500 Linnean Ave. NW. Police said he apparently was driving along Broad Branch Road during the height of the storm, which dumped as much as 3 1/2 inches of rain in little more than an hour.

U.S. Park Police said that the empty, partially submerged Ford Pinto was spotted and reported to them at 9:29 p.m. When it was found against an abutment on the upstream side of the bridge that carries Glover Road over Broad Branch at Broad Branch Road, the car's gearshift was in park and the key was in the ignition, police said. Just south of Broad Branch flows into Rock Creek.

When Litchecon failed to report for work the next morning, he was reported missing, police said. Park Police said they searched the areas immediately downstream of the bridge, but found no traces of the man.

A passerby found the body about 7 a.m. Saturday approximately 150 yards south of where Rock Creek empties into the Potomac.

Police said that Litchecon, a native of the West African nation of Benin, was married and had four children.
