Jo Ann Harris, the chief author of a recently publicized special counsel report scrutinizing the conduct of federal prosecutors and investigators who confronted former White House intern Monica Lewinsky in 1998 about her affair with President Bill Clinton, died Oct. 30 at a hospice in the Bronx. She was 81.

The cause was lung cancer, said her brother, Richard Murray.

Harris’ report, submitted to the Office of Independent Counsel in December 2000, was not widely circulated until The Washington Post recently obtained a copy through the Freedom of Information Act. The report was described in a front-page article published six days before her death.

She was hired by the Justice Department in 1974 and won the conviction in 1982 of the Rev. Sun Myung Moon, the leader of the Unification Church, on conspiracy and other charges stemming from his failure to report $162,000 in income to the Internal Revenue Service.

In 1993 she became the first woman to lead the Justice Department’s criminal division.
