Wong Sun v. United States

In Wong Sun v. United States, 371 U.S. 471, 487-88, 83 S. Ct. 407, 417, 9 L. Ed. 2d 441 (1963) the Court considered whether illegally obtained declarations required the exclusion of narcotics subsequently seized on the basis of those declarations. Much like the facts here the prosecutor "'wouldn't have found those drugs except that the third party declarant helped us to.'" Id. at 487. The Court held the narcotics were discovered by the exploitation of the original illegality and hence they could not be used against the defendant. Id. at 488.
