William Cornelius Sullivan (May 12, 1912 - November 9, 1977) was the Federal Bureau of Investigation's Assistant Director for Domestic Intelligence (Division 5) from 1961 to 1971, serving under Director J. Edgar Hoover as the primary operational architect of COINTELPRO and the FBI's surveillance programs targeting civil rights organizations and political dissidents. Sullivan drafted or oversaw the drafting of the anonymous letter sent to Martin Luther King Jr. in November 1964 suggesting he commit suicide before receiving the Nobel Peace Prize. He was fired by Hoover in 1971 after a falling-out over White House relations, subsequently cooperated with congressional investigators examining FBI abuses, and was shot in what was ruled a hunting accident near Sugar Hill, New Hampshire, on November 9, 1977 - one day before he was scheduled to testify to congressional investigators.¹

Early Career and Rise

Sullivan joined the FBI in 1941 and rose through the ranks under Hoover's patronage. He developed expertise in domestic intelligence matters, particularly the monitoring of left-wing and civil rights organizations for alleged communist influence. By the late 1950s he headed the Domestic Intelligence Division, which made him responsible for COINTELPRO operations after the program was formalized in 1956.

Sullivan was known within the FBI as intellectually aggressive and willing to push the boundaries of domestic surveillance authorities. He developed a close working relationship with Hoover while also building relationships with Central Intelligence Agency counterintelligence figures, including through his collaboration with the CIA's domestic surveillance programs targeting civil rights organizations under Project MERRIMAC and Operation CHAOS.¹

COINTELPRO and King

As head of Domestic Intelligence, Sullivan was the senior FBI official responsible for COINTELPRO operations targeting the Southern Christian Leadership Conference and King personally. Following the announcement that King would receive the Nobel Peace Prize in October 1964, Sullivan supervised the preparation of an anonymous package containing a tape recording from a King hotel room accompanied by a letter characterizing King as a fraud and implicitly encouraging him to commit suicide before the Nobel ceremony. The package was addressed to King and mailed from a post office near the Miami airport on or about November 21, 1964, and was received at the Southern Christian Leadership Conference office in Atlanta, Georgia, which stored it and later sent it to King's home with other tapes.²

The Church Committee recorded that Sullivan testified on November 1, 1975 that Alan Belmont told him Hoover wanted a King tape mailed to Coretta Scott King, that he sent an agent to Tampa to mail a package, and that he did not recall ever having seen the letter given to the committee by the FBI, which he said it was "possible" he had something to do with and which he suggested might have been "planted" in his files.² In his 1979 memoir Sullivan wrote that his division prepared the letter.³ The letter was the most extreme documented example of the FBI's COINTELPRO effort to neutralize King as a civil rights leader, and it appeared in the Church Committee's final report as evidence of one of the most egregious abuses of the program.

Sullivan also supervised the wiretapping of King's phones and hotel rooms, the infiltration of SCLC chapters with informants, and the dissemination of derogatory information about King to news organizations and government officials including the White House and Department of Justice.⁴

Break with Hoover

Sullivan's relationship with Hoover deteriorated significantly in 1970-1971. Sullivan had become associated with Richard Nixon administration desires to use the FBI for White House political intelligence - an orientation that conflicted with Hoover's insistence on personal control of the bureau and its relationships with the administration.

In August 1971, Sullivan wrote Hoover a letter criticizing his leadership. Hoover responded by having the locks on Sullivan's office changed while he was away, preventing his return. Sullivan was effectively fired and formally left the FBI in October 1971.

After leaving the FBI, Sullivan began cooperating with congressional and journalistic investigations into FBI abuses. He wrote a memoir, published posthumously as The Bureau: My Thirty Years in Hoover's FBI (Norton, 1979) - one of the first insider accounts to document Hoover's abuses and COINTELPRO from a senior participant's perspective.¹

Death

On November 9, 1977, Sullivan was shot near his home in Sugar Hill, New Hampshire. The shooting was ruled a hunting accident: a companion identified Sullivan as a deer in low light and fired, killing him. Sullivan was 65 years old.

Sullivan's death occurred during a period of active congressional investigation of intelligence abuses. Accounts of his death describe him as cooperating with the House Select Committee on Assassinations (HSCA), which was then investigating the Kennedy assassination and the question of whether the FBI had withheld relevant information from the Warren Commission, and as scheduled to testify before it when he was shot.⁵ The HSCA stated in a note to its King report that it was unable to take testimony from Sullivan, who was killed in a hunting accident in 1977.⁶ The note adds that Sullivan had testified before the Senate select committee that the project of the anonymous package sent to King, whose final paragraph implied that suicide would be a suitable course of action for him and of which an apparently authentic copy was found in Sullivan's files, had Hoover's prior knowledge and was authorized by the Director, and that Sullivan said he personally opposed the idea; the committee noted that at the time of that testimony Sullivan had broken with the Director, and that his testimony must be viewed accordingly.⁶ The committee stated that if the package was delivered to Assistant to the Director Belmont before mailing, it considered it highly likely that Hoover had before-the-fact knowledge of the action.⁶

Almost immediately after Sullivan's death the HSCA issued a subpoena for any assassination-related documents among roughly 100 boxes of his papers at his home in Sugar Hill; the family's counsel resisted, and a subpoena was served on counsel on March 9, 1978. The committee's interest followed from a 1975 interview of Sullivan by the staff of the House Government Information and Individual Rights Subcommittee, a 139-page transcript of which was in the HSCA collection.⁷

The HSCA examined the March 20, 1968, FBI headquarters memorandum from G. C. Moore, chief of the Racial Intelligence Section, to Sullivan, assistant director in charge of the Domestic Intelligence Division, which recommended releasing a news item stating that King had gone to a white-owned Holiday Inn rather than the Lorraine Motel in Memphis. The memorandum was initialed by Hoover, Sullivan and Moore and bore the notation "handled 4/3/68," whose meaning the committee was unable to determine. The committee was satisfied from Ralph Abernathy's testimony that the memorandum did not cause King to stay at the Lorraine, and stated that the FBI's intent in drafting it "remained an open issue."⁸ It found no evidence that COINTELPRO initiatives of the Memphis field office were tied to the assassination.⁹

The timing of Sullivan's death - the day before planned congressional testimony, during the most active phase of congressional intelligence investigations - has been noted by researchers as part of a broader pattern; New Hampshire Magazine described him as one of several witnesses who died shortly before the hearings began.⁵ The hunting accident ruling was not challenged through any formal legal proceeding.¹
