The use in a criminal prosecution of involuntary confessions constitutes a denial of due process of law under both the federal and state Constitutions. (Lego v. Twomey, 404 U.S. 477, 483 [30 L.Ed.2d 618, 623-624, 92 S.Ct. 619]; Jackson v. Denno, 378 U.S. 368, 385-386 [12 L.Ed.2d 908, 920-921, 84 S.Ct. 1774, 1 A.L.R.3d 1205]; People v. Sanchez, 70 Cal.2d 562, 571 [75 Cal.Rptr. 642, 451 P.2d 74]; People v. Trout, 54 Cal.2d 576, 583 [6 Cal.Rptr. 759, 354 P.2d 231, 80 A.L.R. 2d 1418].) (3) Involuntary admissions are also inadmissible (People v. Underwood, 61 Cal.2d 113, 120 [37 Cal.Rptr. 313, 389 P.2d 937]; People v. Atchley, 53 Cal.2d 160, 169-170 [346 P.2d 764]), and “the due process clause of the Fourteenth Amendment requires exclusion of coerced admissions if they are sufficiently damaging. (Ashcraft v. Tennessee, 327 U.S. 274 ... ; but cf. Stein v. New York, 346 U.S. 156, 162-163, footnote 5 . . . .)”2 (People v. Atchley, supra, p. 170.)
In People v. Berve, 51 Cal.2d 286, 293 [332 P.2d 97], wherein the defendant was beaten and threatened with violence by civilians and confessed to the police shortly thereafter, this court in holding the confession inadmissible stated in part, “No valid grounds for distinction are to be found in the fact that the coercion in this case was inflicted by civilians, and not the police. Decisions holding that confessions are inadmissible because they were rendered under conditions of threatened mob violence by civilians against an accused clearly imply such conclusion. [Citations.] The prohibition which bars the use of involuntary confessions is not only designed as a regulation of the conduct of police officers, but also to insure that an accused’s right to a fair trial is protected. [Citation.] The absence of volition condemns an enforced confession. Due process requires that it be given voluntarily and without promise of immunity or reward.” (See also Maguire, Evidence of Guilt (1959) p. 109, fn. 2.)
The foregoing reasoning in People v. Berve, supra, 51 Cal.2d 286, 293, likewise appears applicable where the confession is not only coerced by, but also made to, civilians, and cases in a number of jurisdictions have concluded that an involuntary confession, whether made to law enforcement officers or private persons, is inadmissible. (People v. Frank, 52 Misc.2d 266 [275 N.Y.S.2d 570, 571-572]; State v. Ely, 237 Ore. 329 [390 P.2d 348, 349]; Fisher v. State (Tex.Crim.App.) 379 S.W.2d 900, 901 et seq.; see State v. Christopher, 10 Ariz.App. 169 [457 P.2d 356, 358].) Thus whether or not the security guards here were pri
