Clementine's father Raymond, as well as her siblings Zepherin and Pauline, were held on suspicion of participating in the murders, but all were released due to lack of evidence. Through Zepherin's confession, three people were arrested as alleged members of the Church of Sacrifice, a man named Ute Thomas of
Port Barre in
Eunice, and a man named Mac Thomas along with a woman named "Duce", both of Lafayette, in New Iberia. Police arrested another Christ's Sanctified Holy Church preacher named Thompson, and accused of having "converted many negroes to the 'sacrifice sect'". Three days after the Opelousas murders, police arrested the Washington family, consisting of husband and wife George and America, and their adult daughter Estelle, as they were the owners of the axe used in the killings. Estelle Washington and Opelousas had been "rival[s] for the affections" of a local man and were recently in court after Washington was accused of assaulting Opelousas. George Washington provided an alibi. On November 25, 1909, Houston Goodwill was arrested by police as the perpetrator of the Opelousas murders. In February, 1911, the Jackson brothers were separately arrested for the murder of the Byers family. Directly after the Andrus family murders, 27-year-old Gaston Godfrey, an African-American inmate at
Pineville Asylum who had escaped a day earlier, was initially arrested, but later released. Another suspect, also black, could not be located. Relation to the Guidry family whom Clementine Barnabet lived with is unknown, though unlikely, as "Guidry" is an extremely common surname in Louisiana. Eliza Richards was arrested on January 27, 1912, on suspicion of having knowledge of the perpetrators behind the Broussard family murders. On January 28, 1912, during the statewide crackdown on those associated with the Church of Sacrifice, two men, identified only as Snyder and "Snap", were arrested in
Glenmora. Both were reportedly members of the Church of Sacrifice. In early 1912, Jim Fields was arrested on suspicion of committing some of the ax murders attributed to Barnabet in Texas. The murders continued during his time in jail. Fields was indicted on May 17, with his trial lasting between May 20 and May 27. It was noted that Fields received a poor court-appointed defense, Gus Miller and Chris Grobe, as this was only Miller's second case and Grobe was excused for being "deathly ill". Charles K. Quin became Grobe's last second replacement and is credited with getting Fields found not guilty by emphasising that all evidence against his client was circumstantial. On June 10, 1912, a man was arrested for selling tablets he dubbed "Paradise Pills" in Lafayette and held on suspicions that he knew of the ax murders. The suspect gave his as J.S. Anderson, but was identified as S.W. Goodman, a Baptist minister who escaped custody in the
Huntsville Unit in San Antonio, Texas. On November 6, 1912, Zepherin Barnabet was again arrested and charged with "lying in wait and stabbing with intent to murder" for injuring Walter Caffery on November 2, 1912. Two others, Zepherin's brother Noah Barnabet and Severin Giroaurd, were also wanted for the attempted murder.
Related deaths Due to increased fears about the supposed "Ax-Man" in Texas, there was heightened vigilance among both state authorities and black citizens, the latter seeing a sharp increase gun ownership, as a precaution against home invasions. As a result, there were deaths and attempted lynchings related to suspected "Ax-Man" activity across the state between 1911 and 1912. In
Smithville, teenage boy Max Warren, who had a history of
sleepwalking, was shot by his neighbor West Duval, who had been standing guard outside the house that night. In
Gonzales, a woman was forced out of town due to rumors of a "strange Negro woman missionary" claimed to be affiliated with the Church of Sacrifice. In Acadian regions of Louisiana, there was an increased demand for protective "charms" and amid a high of self-proclaimed "hoodoo doctors", Lake Charles Police Department mounted officer Ira E. Barker shot and killed A.E. Johnson, a "lightning-rod salesman" from
Opelousas, after the intoxicated Johnson became belligerent during questioning. == Modern assessment ==
