What is the test for admitting a piece of rebar in a motor vehicle accident?

The rebar, however, was properly admitted, as it was not a product of the statements elicited after defendant's requests were made. Defendant had already given the rebar's rough location in the prior dream sequence, and his subsequent affirmation of the location was essentially repetitive. Furthermore, defendant's later on-the-scene assistance was apparently unnecessary to the rebar's recovery. An officer found it 50 yards away from the location defendant had described, while defendant was looking with other officers elsewhere. Under those circumstances, the rebar was not the fruit of the unlawfully obtained statements. (Wong Sun v. United States (1963) 371 U.S. 471, 83 S.Ct. 407, 9 L.Ed.2d 441.)
