As a Wichita, Kansas police laboratory investigator, he was called out to the crime scene of the Earl and Ruth Bowlin murders in Sedgwick County on April 13, 1963.
[5] Though he had never previously tried a case,[1] he was first elected as Attorney General of Kansas in 1970 under a platform of "aggressive and visible enforcement of the state's drug and liquor laws".
[6] As attorney general, Miller participated in arrests and drug raids himself; a 1971 article detailed a Wichita drug raid in which Miller hid in the trunk of a car of an undercover agent in order to make arrests.
[11] Miller sent letters requesting Braniff International, TWA, and Continental halt sale in respect for state law, and told reporters that he had gotten a telegram from one airline promising to suspend beverages while over Kansas.
Miller then served as Sedgwick County Prosecuting Attorney from 1976 to 1980 and opened up a law practice in his hometown of Wichita.
