Carl W. Hurst Jr., 85, who retired from the FBI in 1979 as director of the special inquiry and civil rights section, died Sept. 16 at his home in Arlington County.

He had heart disease and lymphoma, said his daughter, Catherine DeBenedetto.

Mr. Hurst joined the FBI in 1949. Early in his career, he investigated Puerto Rican nationalists linked to the 1950 attempt to assassinate President Harry S. Truman and the 1954 shooting in the House of Representatives in which five congressmen were wounded. He was later section chief of the FBI’s “Ten Most Wanted” fugitive program.

Carl Wilson Hurst Jr. was born in Bessemer, Ala., and served with the Navy in the Pacific during World War II. He was a 1949 graduate of George Washington University and attended GWU’s law school.

In retirement, he worked for several law firms in the Washington area on personal injury cases involving the use of firearms.

His wife of 61 years, Jane Luers Hurst, died in 1961.

Survivors include two children, Catherine DeBenedetto of Manassas and Wilson Hurst of Warrensburg, Mo.; and two grandsons.
