In Duff v. State, 546 S.W.2d 283, 287 (Tex. Crim. App. 1977), a police officer stopped the appellant's car for speeding. Id. at 284. The appellant's passenger told the police officer that he was a hitchhiker who had been picked up only five minutes prior to the stop by the officer, whereas appellant said that the passenger had traveled with him from Corpus Christi to Austin. Id. The court described these differing stories, when coupled with other circumstantial evidence, as a "circumstance implying guilt." Id. at 288.
