In Wilson v. State, 473 S.W.2d 532, 534 (Tex. Crim. App. 1971), the defendant made an unwritten statement in which he admitted leaving a stolen car at a specific location. The officers to whom the statement was made went to the specified location, but did not find the car. The officers learned that another police officer had already found the car and impounded it. Nevertheless, the statement was deemed admissible because "it led to the recovery of the stolen car." Id. at 535. Implicit in the decision is that the prior knowledge of the impounding officer was not imputed to the officers to whom the statement was made.
