What is the test for a motion to suppress or suppress testimony in a criminal case?

violation of Miranda v. Arizona (1966) 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694. Defendant testified at a hearing on the motion, but the trial court ordered defendant's testimony stricken in its entirety after he refused to answer one of the prosecutor's questions during cross-examination. The court ultimately granted the motion to suppress in part, ruling that some of the custodial statements were improperly obtained. Of those statements that the court found admissible, only one was presented to the jury in the prosecution's case-in-chief.
