Edmund M. Sciullo Sr., 67, a retired trial attorney for the Federal Communications Commission and a Navy veteran of World War II, died Wednesday at the Veterans Administration Hospital of hemochromatosis, a metabolic disorder that affects the kidneys and other organs.

After serving in the Navy from 1943 to 1946, Mr. Sciullo was a lawyer in private practice here for several years.

From 1959 to 1965, he was an attorney with the old Federal Power Commission. For a short time thereafter, he was staff counsel to the House Interstate and Foreign Commerce Commitee's special subcommittee on investigations. He then joined the FCC, from which he retired last year.

Mr. Sciullo was born in Waterbury, Conn. He graduated from the College of the Holy Cross in Worcester, Mass., and from Harvard Law School.

He lived in Kensington for 29 years and was a member of the D.C. and Federal bar associations.

Survivors include his wife, Mary E., of Kensington; two daughters, Mary Ann O'Farrel of Waldorf, Md., and Veronica Sciullo of Cheshire, Conn.; a son, Edmund M. Jr., of Annandale; a sister, Florence Capone, of Simsbury, Conn., and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the hematology research divisions of the Vetrans Administration Hospital and Georgetown University Hospital.
