A Washington attorney who was president of a maritime lobbying group has been found shot to death near Savannah, Ga., more than two weeks after he disappeared from a national AFL-CIO meeting in Bal Harbour, Fla.

Chatham County, Ga., police said last night that the body of Julian H. Singman, 56, president of the Maritime Institute for Research and Industrial Development, was found by a boatman Monday afternoon in a seaside creek on Wilmington Island, along the Savannah coast.

Singman's brother, Henry, of Silver Spring, said police told him that Singman had been shot several times and that his body had been in the water several days.

Police would not comment on a reported arrest in the slaying.

Julian Singman was last seen Feb. 15 in Bal Harbour when he told associates he was going to meet a man who was interested in buying his 56-foot yacht, according to his brother. The boat, the Calpurnia, served as Singman's residence and is docked at 1000 Water St. SW.

A native Washingtonian, Singman graduated from George Washington University, attended Oxford University and received a law degree in 1953 from Harvard University.

He formerly was assistant chief counsel of the House Small Business antitrust subcommittee and was of counsel to the D.C. firm of Landis, Cohen, Rauh and Zelenko.
