In Brown v. Illinois (1975), 422 U.S. 590, 599, 95 S.Ct. 2254, 45 L.Ed.2d 416, the United States Supreme Court set forth three factors for courts to consider in determining whether the causal chain has been sufficiently attenuated: "[the] temporal proximity of the arrest and the confession, the presence of intervening circumstances, and, particularly, the purpose and flagrancy of the official misconduct." Id. at 603-604. The question of whether a confession has been tainted by an illegal arrest must be decided on the facts of each case; no single factor is dispositive. Id. The burden of showing admissibility rests with the prosecution. Brown, supra. In Brown v. Illinois, 422 U.S. 590, 45 L. Ed. 2d 416, 95 S.
