Have you seen the letters written by L. A. Pindall which are on file at the Missouri Historical Society in St. Louis?

There's one dated Feb. 3rd, 1869, discussing Pindall's agreement with Capt. [Silas?] that General Parsons was murdered by the same officer who presided over the court marshal of Emperor Maximilian. Pindall goes on to say that this was Escobedo's [Adjutant?] General. Later in the letter, he says that the account of Parsons' death by Capt. [Silas?] and Col. D.A. Williams of Shelby's brigade, substantially agree. This leads him to conclude that an officer of the Liberal Army, Col. [Phalon?] Sanchos, murdered General Parsons for money. Pindall believed the murder took place 9 miles east of the San Juan River on the Camargo and Monterrey Road and he speculated that Parsons' remains were left unburied.

In another letter, dated August 31, 1871, he tells Mrs. Mildred Standish that Morrison is sending a package of General Parsons' papers from New Orleans along with some of Pindall's papers. Pindall says that he is going to send his own papers to Dr. Bell in Hannibal and that Dr. Bell would like to have the General's papers sent to him as well, although, the more valuable part of his papers couldn't be found.
