But in 1967 and 1968, Bowers faced a major obstacle: the non-stop surveillance and scrutiny of federal law enforcement. Agents in the Jackson, Mississippi, field office engaged in what amounted to a virtual war with the Mississippi KKK. Bowers always took extraordinary measures to avoid surveillance. When he gave the aforementioned 1964 speech about the “enemy’s . . . final push for victory” before the MIBURN killings, Bowers did so in a remote building so that Piper airplanes could provide aerial warning of any potential law enforcement observers or raids.17 The audience had been body-searched upon entry. At one point, he proposed firing the entire leadership of the White Knights out of concern that some might be informants. In 1967, with his one-time close aide Delmar Dennis prepared to testify against Bowers and others at trial, Bowers was more cautious than ever. The FBI’s efforts denied him freedom of movement and access to his lieutenants and foot soldiers.
Bowers responded to this in a familiar way: he turned to outsiders to advance his plans to kill King and engage in white supremacist violence. As described in detail in Chapter 1, the White Knights floated a high-money bounty offer to the Dixie Mafia to kill King. In researching Donald Nissen’s claims, something became clear: unbeknownst to Nissen, Leroy McManaman, the hoodlum who offered him the bounty at Leavenworth, very likely participated in the 1964 Sparks-McManaman plot on King. McManaman belonged to the same cadre of Dixie Mafia gangsters as Don Sparks, a group headquartered in Tulsa, Oklahoma. McManaman knew Sparks personally according to Robert “Rubie” Charles Jenkins, a fellow member of the Tulsa gang and Sparks’s closest friend. McMamanan, in turn, partnered with Jenkins in an interstate car-theft ring that landed both men in federal prison in 1964.18 But McManaman, who somehow secured a commutation from the Kansas governor against the wishes of a state prosecutor in 1952,19 also managed to win a rare federal appeals bond in 1964. This allowed McManaman to temporarily leave Leavenworth while he challenged his 1963 conviction in the Tenth Federal Circuit Court of Appeals. The court’s jurisdiction included Kansas, where McManaman and Jenkins were originally convicted, and five other states.20 But McManaman not only imperiled his appeal, he risked adding years to his prison sentence: he spent weeks outside of Kansas, staying with a married real estate broker, Sybil Eure, in Jackson, Mississippi, in the spring of 1964. Thus McManaman, whose criminal activity rarely included Mississippi, found his way to the Magnolia State at the same time that his friend, hitman Donald Sparks, took refuge at a Jackson motel, waiting for the money to kill King. There’s little doubt he was there to assist Sparks in King’s assassination, but the bounty money never arrived, McManaman’s appeal failed, and he had to return, before Freedom Summer began, to Leavenworth to serve out his sentence.
It is critical to note that Eure is the woman whose name McManaman provided to Donald Nissen as a go-between if Nissen wanted to join the 1967 King murder conspiracy. She was the first person the FBI interviewed to follow up on Nissen’s revelations about the plot in the Sherman, Texas, jail. Eure denied any connection to a King bounty; her explanations for how she knew McManaman defied credulity, including the claim that an unidentified friend recommended McManaman to her as an expert on real estate.21 Putting aside the dubious notion that a middle-class woman in Jackson would share a mutual connection to a hardened career criminal—and that her friend would encourage Eure to shelter that criminal for weeks—McManaman’s only background in real estate was running an illegal gambling operation out of an inn he ran in Colorado. McManaman’s prison records reveal a much deeper relationship than Eure admitted: he hoped to marry her when he got out of Leavenworth, and she was his most frequent visitor while he stayed behind bars.22
The FBI neglected another important revelation by Eure. Asked if she knew anything about the other two go-betweens that McManaman spoke of to Donald Nissen, Eure provided some interesting answers. She told the agents she knew a Floyd—her own brother, Floyd Gardner. This Floyd, however, was not the Floyd referenced by McManaman, as will become clear in Chapter 5, but the FBI did little to investigate. Eure also identified two men she knew who were connected to the federal marshals office in Mississippi: Charlie Sutherland, a cousin, and Robert C. Thomas, an associate. Neither of them, she asserted, would have anything to do with the Klan or a plot on King’s life.
Interviews conducted by the authors with people familiar with Sutherland and with Sutherland himself confirm Eure’s assertions about her cousin. But Robert C. Thomas, as federal authorities would learn soon after the King assassination, did associate with the Ku Klux Klan. Before he began work as a clerk with the southern district court in Mississippi, Thomas was appointed as the chief investigator for the Mississippi State Sovereignty Commission, a state government agency that spied on civil rights groups in Mississippi as part of the state’s wider effort to resist federally imposed integration. But as a clerk for the federal courts, Thomas illegally rigged juries on behalf of Sam Bowers. Nissen did tell the authors that McManaman specifically noted that the go-between had recently been appointed as a deputy marshal in Mississippi. This would seem to eliminate Thomas as a candidate (he was only a clerk). But at the time that McManaman stayed with Eure, Thomas had been in the news for having been deputized as a marshal temporarily, to help law enforcement as needed, if civil rights protests got out of hand. And, as a clerk in the court, Thomas was in a unique position to cover for McManaman as he violated his appeal bond and visited Mississippi. He could have, for instance, provided false documentation to show that McManaman was in Jackson to provide information to authorities there. No record indicates that the FBI investigated either Sutherland or Thomas as the potential go-between Nissen cited in his July 2 warning about the King plot.
This is because the FBI accepted Eure’s claims of innocence and ignorance without a qualm. They arranged a cursory follow-up investigation at Leavenworth, and did not even bother to interview McManaman until months after the King assassination, even after John May corroborated parts of Donald Nissen’s story. A respectable Southern woman like Eure, they reasoned, would not involve herself in anything like a KKK murder conspiracy. On one level this observation dovetailed with history: women played an important support role for the KKK but they almost never participated in acts of terrorism or assumed positions of leadership. But the FBI, once again, underestimated Sam Bowers. At the very moment the FBI visited Sybil Eure,23 Sam Bowers was planning yet another way around the FBI’s non-stop surveillance, and it included employing a Jackson woman, Kathy Ainsworth, among a team of terrorists.
The choice to use Ainsworth as a terrorist starting in 1967 was a stroke of evil genius. An attractive young elementary schoolteacher, she did not fit any of the stereotypes usually assigned to Klan members, allowing her to keep her terrorist activities hidden even from a vigilant FBI. But Ainsworth embraced racial and ethnic resentment as stridently as anyone who ever burnt down a black church or attacked a civil rights protestor. Raised by a virulently racist single mother, Margaret Capomacchia, Ainsworth was mentored in white supremacy by Sidney Crockett Barnes, a vile bigot who fled Florida to Mobile, Alabama, after a law enforcement crackdown on racial violence. Barnes did not stop his support for terrorism, becoming part of a failed 1963–1964 plot against Martin Luther King Jr.’s life that will be detailed in the next chapter. Both Barnes and Margaret Capomacchia enjoyed close connections to Klansmen in Mississippi, and Barnes sent his daughter to college there, with Kathy as her roommate.24 Kathy later joined the Americans for the Preservation of the White Race in Mississippi, a front group for the Mississippi White Knights, but privately worked closely with both the White Knights and the United Klans of America. She even kept her militant associations secret from her husband, a man Sidney Barnes, the surrogate father who gave her away at her wedding, did not approve of as her spouse.
