I could not find anything on the murder itself, but I did find mention of Jodie Hamilton. One reference was that Jim Cantrell served as deputy and helped capture Jodie Hamilton for the murder of the Parson family. Another reference is that in 1906, Jody Hamilton killed the Parson family in the Boiling Springs area. He had been arrested by Sheriff Wood and put in the Houston jail. Wood heard rumors that some people were going to break Hamilton out of jail and give him his just due without a trial. Sheriff Wood sneaked Hamilton from the jail. Albert Parmenter was waiting with his best horses to drive them swiftly to Cabool to put Hamilton on a train for safekeeping in the Springfield jail. Before they reached Cabool, Albert Parmenter said he could hear the crowds shouting behind, trying to catch them before they reached the train. In time, Jody Hamilton was hanged on the Houston courthouse lawn for his dirty deeds.
