How is the erroneous admission of a statement obtained in violation of the Fifth Amendment/Miranda?

We turn, then, to the question of prejudice. The erroneous admission of a defendant's statements obtained in violation of the Fifth Amendment/Miranda is assessed under the beyond-a-reasonable-doubt standard of Chapman v. California (1967) 386 U.S. 18, 24 (Chapman). (Elizalde, supra, 61 Cal.4th at p. 542; People v. Davis (2009) 46 Cal.4th 539, 598.) "That test requires the People here 'to prove beyond a reasonable doubt that the error complained of did not contribute to the verdict obtained.' [Citation.]" (Elizalde, supra, at p. 542.)
