When peace once more brooded over the land, he returned to Missouri, and commenced a commission business in St. Louis, with J. W. Shawhan for a partner, under the style of Shawhan & Co. This was in 1866. It does not appear that the firm was very successful. Parmer is said to have lost several thousand dollars in this venture. Later, the business was closed out. Payne Jones, and some others, among them Jim White, a friend of Parmer, were implicated in a bank robbery at Richmond, Mo. Mayor Shaw was killed at that time. Suspicion attached to Parmer as being one of the robbers, and he was arrested, but, on examination, discharged. Then he led a sort of roving life for some years, sometimes in Missouri, then in Texas, sometimes in Colorado, then in the Indian Territory. Finally he came to regard Texas as his home. In 1870 he returned to Jackson county, where his boyhood had been passed. For a long time his relations with the James family had been friendly, and when he came to woo Miss Susan James, the sister of Frank and Jesse, she did not deny his suit, and they were married, and removed to Arkansas the same year. He remained in that state during the autumn and winter, and in the spring of 1871 he removed with his family to Texas. For a time, his wife taught a school at Sherman. Subsequently, Parmer established a ranche near Henriette, Clay county, Texas, about 120 miles west of Sherman. Clay county lies on the Red river, directly south of the Kiowa Indian reservation. Here he had all the freedom he desired, and for some years he tended his herds and was prosperous. He frequently made trips to Kansas City, St. Louis and Chicago with droves of cattle. When the train robbery at Glendale took place, the authorities sought for clues to the robbers in every direction. Mr. Grimes, the express messenger who was knocked down by one of the robbers who wore no mask, was able to give a vivid and minute description of the features of his assailant, and that description suited the personnel of Parmer. Deputy Marshal Whig Keshlear was dispatched to Texas by Marshal Liggett to effect Parmer's arrest. He proceeded to Sherman, where he met and conferred with Mr. Everhart, sheriff of Grayson county. That officer readily consented to assist in the arrest of Parmer, and proceeded at once to his ranche, near Henriette. The officers effected the arrest without difficulty on the 2d day of November, 1879, under a requisition from Governor Phelps, of Missouri.
