On August 9, the Webster Parish Coroner, Dr. Richardson, was notified that some fishermen had found a body on a private pond. Louisiana NAACP officials became aware of the lynching and investigated. The Louisiana NAACP officials had not been exposed to depravity of this nature, as they would soon discover. During the NAACP investigation, a Minden embalmer told them that "Jones had been burned about the face and body with a blowtorch, that he was mutilated and that his wrists were gouged out with a cleaver and that his eyeballs had popped out of his skull." Many northern newspapers picked up the story, and TIME magazine published an article in the August 26, 1946 edition. Two other 1946 lynchings had occurred in Columbia, Tennessee and Monroe, Georgia, prior to the Minden debacle, and despite resistance and consternation from J. Edgar Hoover, and a no bill returned from a local grand jury, the FBI began a thorough investigation at the behest of Thurgood Marshall and U.S. Attorney General Tom Clark. A Federal grand jury indicted six mob members on October 16, 1946, including Webster Parish Sheriff's Deputies O.H. Haynes, Jr. and Charles Edwards, and Minden Police Chief Benjamin Gantt. The defendants were charged with violating 3 sections of Title 18 of the U.S. Code. The charges against Gantt were eventually dismissed by U.S. Attorney Malcolm Lafargue as part of his deal to testify against the others. Early motions were filed challenging the sufficiency and constitutionality of the counts in the indictment, but they were quashed by Judge Gaston Porterie. Harris, Jr. and his father had endured many hours of FBI interviews, as well as having to return to Louisiana from the North and testify in what was a hostile atmosphere. Both father and son were composed and able to remember all of the details of the ordeal that they had experienced. The defense strategy was to paint the father and son as willing dupes of the NAACP, and to affirm the Southern strategy of disdain of Federal intervention in civil rights matters. Defense witnesses and alibis were easily refuted by the U.S. Attorney. Under defense questioning, Harris, Jr. could not place three of the five defendants at the scene of the crimes- even though he had always maintained that he only saw the complainant's husband's father and Deputy Sheriff O.H. Haynes, Jr. during the ordeal. Various Federal witnesses were attacked by the defense as having been told what to say and testify to in court. Three people testified, concerning Jones' alibi, that he had been playing dominoes at their house during the time of the alleged prowler in the yard, but they were attacked by the defense and accused of being told what to say by the FBI. A trustee testified that he had seen Deputy Haynes, Jr. and another deputy beat Jones and Harris, Jr. in the jail a day before they were released. Most damaging of all was the testimony of Benjamin Gantt, Minden Police Chief, whose statement indicated that Deputy Haynes, Jr. had deprived the victims of their rights under color of law multiple times and had also conspired with the mob members. Other witnesses testified, including the coroner, Dr. Richardson. Jones had been accused of having lewd pictures on his person, but they were undoubtedly planted postmortem. Various phone-company employees testified that they had witnessed the commotion outside of the jail on August 8. Two brothers testified that they saw two of the mob members driving their cars- which matched the description given by countless witnesses of the August 8 release from jail- to Minden from Cotton Valley, in the evening hours of August 8. In the end, none of the evidence could defeat Jim Crow and the Southern strategy. All five defendants were acquitted by a jury of twelve white men.
