Despite Sul Ross's claim that Peta Nocona was killed at Pease River, his son insisted he was not present, and died several years later. This claim is supported by Texas historian John Henry Brown. Brown had already disputed the identity of the person killed at Mule Creek, before Quanah Parker came onto the reservation, stating he was told the name of the man killed at Pease River was Mo-he-ew, not Peta Nocona. Quanah Parker then wrote an affidavit disputing his father's death: "while I was too young to remember the chief, it is likely that Brown was correct" (but the killed warrior's name results to have been Nobah, a former captive adopted in the tribe).
