You are right! According to the book I mentioned before he was never convicted for the shooting.
Here's what the book had to say about him: Notes from "Caldwell Parish in Slices-Biographies"(**Not all of the info appears to be correct. Caroline to my knowledge was a Choctaw Indian, not Spanish.) ..."After the close of the Civil War, Dr. Fluitt remained in New Orleans for a time where he married a nurse, who was of Spanish nationality and skilled in the art of medicine. He was induced to come back to Caldwell Parish, and he and his wife settled in the western section of the parish, in Ward 9. Here they had two children, Lillian and Julia. Lillian became Mrs. Wesley Book, and Julia married C.A. Meredith, a great grandson of Thomas R. Meredith, being descended through Asa Meredith and Thomas Meredith. Mrs. J.M. Medaries and many others here are descendants. Uponthe death of his wife, she was buried in the Old Bethel Cemetery, west of Clarks. There is no marker over her grave, but it is said that her resting place is beside the grave of her husband. ...Dr. Fluitt later married Margie Black, whose husband, A.O. Black , had died at the age of 34 on Oct. 16, 1900. it was he who gave the land for the site of the Black Cemetery, located in Ward 6 in the Sardis community. She was very much younger than Dr. Sam, as he was called; she was the sister of Wiley Welch, who served as Sheriff of Caldwell Parish for 10 years from 1902-1912, and by her previous marriage to Mr. Black had 4 children, three sons, Kirk, Crawford, Aubrey, and a daughter Mrs. James W. Childress, who is now living in the old Fluitt house. Dr. Sam was by no means a "Pistol Packing Sawbones".He owned no gun, but somewhere after the turn of the century prior to 1911, he killed a man by the name of Collins. The time was shortly after the now liquidated Louisiana Central Lumber Company set up operation at Clarks and was extending its railroad tracks west into the vicinity of Cotton Plant, and later Camp 24 was established.Afterthe incident, the doctor moved to the home of a relative in Riverton to spend the remainder of his life. What motivated the killing is now immaterial and beside the point. But the doctor was too well liked by the public and no trial was ever held."
