McCurdy's final robbery took place on October 4, 1911 near Okesa, Oklahoma. McCurdy and two accomplices planned to rob a Katy Train after hearing that it contained $400,000 in cash that was intended as royalty payment to the Osage Nation. However, McCurdy and the men mistakenly stopped a passenger train instead. The men were able to steal only $46 from the mail clerk, two demijohns of whiskey, an automatic revolver, a coat and the train conductor's watch. A newspaper account of the robbery later called it "one of the smallest in the history of train robbery." McCurdy was disappointed by the haul and returned to Revard's ranch on October 6 where he began drinking the demijohns of whiskey he stole. By this time, he was also ill with tuberculosis (which he developed after working in mines), a mild case of pneumonia and trichinosis. He stayed up drinking with some of the ranch hands before going to sleep in the hay loft the following morning. Unbeknownst to McCurdy, he had been implicated in the robbery and a $2,000 reward for his capture was issued.
