The trial judge instructed the jury as follows: “In order to establish a defense of insanity the accused must establish that a disease or other defect of his mind had so impaired his reason that at the time of the criminal act with which he is charged either he did not know that such act was wrong or he did not have the ability to refrain from doing that act.”
This charge was erroneous under R. C. 2901.05(A). State v. Robinson (1976), 47 Ohio St. 2d 103, 351 N. E. 2d 88; State v. Meyer, decided with State v. Humphries (1977), 51 Ohio St. 2d 95, 364 N. E. 2d 1354.1 Under the statute, a defendant who pleads not guilty by reason of insanity has the burden of going forward with evidence of a nature and quality sufficient to raise the defense before the jury. Under the statute, the correct rule is that once the defendant has presented evidence of a nature and quality sufficient to raise the defense before the jury, the jury must consider all of the evidence in the case from whatever source, including all of the evidence as to the affirmative defense; and if they entertain any reasonable doubt of the defendant’s guilt, they must acquit. If they entertain no reasonable doubt of the defendant’s guilt, they must convict.2
*243The instruction in the present case suggested that the jury could not acquit the defendant unless he actually “established” the defense in the jury’s mind by some unspecified quantum of proof. Thus the instruction imposed on the defendant a greater burden of proof than the law allows, and it was, therefore, prejudicial error. State v. Hauser (1920), 101 Ohio St. 404, 407, 131 N. E. 66, 67; Kelch v. State (1896), 55 Ohio St. 146, 45 N. E. 6. See, also, the civil cases of Schwartz v. Badila (1938), 133 Ohio St. 441, 14 N. E. 2d 609; Indus. Comm. v. Ripke (1935), 129 Ohio St. 649, 196 N. E. 640; Cleveland Ry. Co. v. Goldman (1930), 122 Ohio St. 73, 170 N. E. 641; Montanari v. Haworth (1923), 108 Ohio St. 8, 140 N. E. 319.
The jury propounded seven questions in their attempt to understand the court’s charge as to the burden of proof on the affirmative defense. The court’s answers to those questions compounded the error in the charge. In answer to one question, the court stated that the defendant had no burden of proof regarding insanity. In answer to another question the court said that the state had no such burden. These two answers are incomplete and, thus, misleading. It is generally true that the burden of initial production on a given issue can be assigned to one party or the other. But once an issue is properly before the trier of fact, the crucial question is no longer which party has the burden of proof, but rather the standard by which the trier of fact is permitted to draw inferences from the evidence as a whole. As Wigmore says, “After * * * the jury has retired to reach and frame its decision, a question arises as to the quality, or degree, of its persuasion. Here, it is to be noticed, we are no longer concerned with the incidence of the duty or burden of proof as between the parties to the cause, but merely with the tribunal’s own duty and conduct as to its standard of persuasion.” (Emphasis sic.) 9 Wigmore on Evidence (3 Ed.), 316, Section 2497. In the *244present ease, the court’s answers to the jury’s questions came close to explaining this, but they omitted the vital information which the jury needed in order to decide on the affirmative defense. They omitted any explanation of the standard by which the jury must decide that issue. The court did not explain that when the trier of fact has considered all of the evidence, including all of the evidence as to the affirmative defense, the trier of fact must acquit the defendant if the trier of fact entertains a reasonable doubt as to the defendant’s guilt, or if the trier of the fact entertains no reasonable doubt as to the defendant’s guilt, the trier of fact must convict the defendant. For these reasons the judgment must be reversed.
The appellant also argues that the verdict was against the manifest weight of the evidence because the defense evidence on the issue of insanity was “substantial,” “credible,” and “essentially unimpeached and unrebutted.” Actually, however, the state offered a rebuttal witness who questioned the diagnosis advanced by the psychiatrist who testified for the defense. The evidence as a whole was such that reasonable jurors, properly instructed, could have disagreed as to the appellant’s sanity. Thus, the issue of insanity was a question for the jury, and this court can not now hold that the defendant was entitled to acquittal as a matter of law on the evidence presented on the question of insanity at the time of commission of the crime.
The other important point in this case is whether the self-incriminating statements which the appellant made under interrogation by the police were properly admitted in evidence.
The first question in this regard is whether the appellant’s statements should have been excluded under Miranda v. Arizona (1966), 384 U. S. 436. Miranda applies to ‘‘questioning initiated by law enforcement officers after a person has been taken into custody or otherwise deprived of his freedom of action in any significant way.” Miranda, supra, at 444. As the statement of facts shows, there can be no real disagreement that the appellant’s freedom *245of action was restricted significantly at all times after his first encounter with Detective Lower in his apartment. Lower asked the appellant to wear certain clothes, told him not to take his car keys with him, and later refused to let his friend speak to him on the telephone, even though he was in the room when one of the calls came through. The appellant was transported twice in police vehicles, and from about 10:45 a. m. until just after he confessed, late in the evening, he saw no one except police personnel. The state insists that the appellant was free to leave the custody of the police at any time, but this fact was never communicated to the appellant.
The record is equally clear, though, that the police formally complied with the Miranda requirements. The appellant twice heard the warnings and twice waived, in writing, his right to remain silent and his right to have an attorney present. Moreover, the appellant at least once, and perhaps twice, declined Detective Lower’s offer to let him speak to someone besides Lower, such as an attorney.
Nevertheless, a waiver of the right to counsel is ineffective unless made knowingly and intelligently. See Argersinger v. Hamlin (1972), 407 U. S. 25; State v. Wellman (1974), 37 Ohio St. 2d 162, 309 N. E. 2d 915. The appellant argues that his waivers were no longer knowing and intelligent after the police concealed the fact that two attorneys had been to the station and had asked to see the appellant. This was one of the grounds on which the trial court held the appellant’s statements inadmissible. The Court of Appeals, however, properly reversed on this point. The appellant never asked to see any attorney, let alone the particular ones who came to see him, and when directly asked whether he wanted to talk to a lawyer, he answered “no.” When he was asked which relatives should be notified of the decedents’ deaths, the appellant gave only the names of relatives and did not ask that a lawyer be notified. Furthermore, the only connection between the appellant and the two lawyers who asked to see him was *246that one of them had done legal work for the deceased father. In their conversation with Chief Abbott, neither attorney asserted that he represented the appellant.
The present case differs from Commonwealth v. McKenna (1969), 355 Mass. 313, 244 N. E. 2d 560, reaching the opposite result where the two lawyers who demanded to see the suspects during interrogation were the same attorneys whom the suspects had earlier asked to have notified; and Commonwealth v. Mahnke (Mass. 1975), 335 N. E. 2d 660, where the lawyer who asked to see his client during interrogation was said to be “defendant’s attorney.”
However, another issue remains to be considered.
Long before Miranda, it was well established that a confession, to be admissible, must be voluntary. As was said in Rufer v. State (1874), 25 Ohio St. 464, 470, “Whilst voluntary confessions are always admissible against a prisoner on trial, it is well settled that confessions of guilt made through the influence of hopes or fears, induced by promises or threats of temporal benefit or disadvantage, are wholly inadmissible.” This rule is now a matter of federal constitutional law. Rogers v. Richmond (1961), 365 U. S. 534. Miranda, of course, laid down minimum requirements which the police must observe in conducting custodial interrogations. But, as this court has held, the question of whether the accused’s statements were in fact voluntary is separate from the quesion of compliance with Miranda. State v. Kassow (1971), 28 Ohio St. 2d 141, 277 N. E. 2d 435; see, also, State v. Hooper (1971), 25 Ohio St. 2d 59, 63, 267 N. E. 2d 285. Moreover, formal compliance with the requirements of Miranda does not preclude proof that the statements themselves were involuntary. See Kassow, supra, at page 145.
In this cause, the trial court’s original decision to exclude the statements in question rested on three independent grounds, one of which was that the appellant’s statements were involuntary. The factual question facing the trial court on the motion to suppress was “whether the *247defendant’s will was overborne at the time he confessed,” Lynumn v. Illinois (1963), 372 U. S. 528, 534, or in other terms, whether his confession was “made freely, voluntarily, and without compulsion or inducement of any sort” (Wilson v. United States [1896], 162 U. S. 613, 623). See Haynes v. Washington (1963), 373 U. S. 503.
The appellant made no self-incriminating statements until he was taken to the State Highway Patrol headquarters, where the two examiners told him repeatedly not to take the test if he had anything to hide. They also assured the appellant repeatedly that they were only interested in his welfare, and told him further that if he would “talk” to them, they would get him “help.” To a 19-year-old suspect with no prior experience with the police, except for a minor trespassing charge, this might well have seemed like an offer of leniency. Under the rule that “ * a confession * * * must not be * * * obtained by any direct or implied promise, however slight,’ ” Bram v. United States (1897), 168 U. S. 532, 542, the trial judge, in the opinion of the writer, could properly hold that appellant’s subsequent statements were inadmissible.
Finally, at the crucial moment when the interrogators confronted the appellant with the polygraph results, they refused three times to let him speak to his close friend, Kay Callendine, unless he would first explain his answers to the polygraph examination. In the opinion of the writer, the trial court could reasonably find that the ensuing statements were involuntary, as in Haynes v. Washington, supra. There, the United States Supreme Court held the suspect’s confession involuntary partly because it was given after the police had denied his requests to speak with his wife. Although Haynes included additional facts that doubtless made it somewhat easier to decide than the present cause, the investigatory technique used here is the same as that used in Haynes. It was an offer for an exchange — access to a person close to the suspect, in return for further statements.
It is well settled that the question of whether to ad*248mit or suppress confessions claimed to he involuntary depends on “all of the attendant circumstances.” Haynes, supra, at page 513.
As this court said in State v. Cowans (1967), 10 Ohio St. 2d 96, 101, 227 N. E. 2d 201, “Whether a confession is voluntary or not is not subject to mathematical calculation. Rather a court must look at all the attendant circumstances to determine the psychological impact of the coercive influences on the suspect’s ability to make a free and rational choice.”
It is the opinion of the writer that the attendant circumstances in relation to appellant’s statements show that the statements were involuntary and thus inadmissible. However, a majority of the court is of the opinion that appellant’s statements were not involuntary and hence were admissible. Therefore, the judgment of the Court of Appeals with respect to its holding that appellant’s statements were admissible is affirmed.
The judgment of the Court of Appeals is reversed in part and affirmed in part and the cause is remanded to the trial court for a new trial.
Judgment accordingly.
