How have the courts interpreted voluntary statements by a defendant in a sexual assault case?

In sum, defendant's statements were voluntary as there was (1) no discussion by the police of anything other than defendant cooperating and telling the truth, (2) no undue pressure amounting to coercion, (3) no express or implied promise of any specific benefits he might receive or any harm that might occur if he did not confess, and (4) no dishonesty and trickery that amounted to a false promise. (People v. Holloway, supra, 33 Cal.4th at p. 115.)
