*233 Opinion
Appellant was indicted on September 3, 1974, for the murder of his wife, Maiy Jo, on or about October 18, 1972. He was arraigned and pleaded not guilty. Jury trial commenced November 10, 1974, and on December 12, 1974, the juiy found appellant guilty of murder in the first degree. He was denied probation and sentenced to the term prescribed by law.
Because we have concluded that appellant’s conviction must be reversed due to the prosecution’s failure to prove that appellant knowingly and intelligently waived his Miranda rights before he was interviewed by Dr. Lunde, we need only briefly summarize the facts.
Appellant and Mary Jo were married in 1968. In March 1970, they moved to McKinleyville, California, so that appellant could attend Humboldt State College. In October 1970, their daughter, Rachel, was bom. Thereafter, marital troubles began, and appellant and Maiy Jo constantly argued about Rachel. Appellant said he would give Maiy Jo a divorce if he received custody of Rachel.
In July 1972, Mary Jo, with Rachel, left appellant. They lived several weeks with her parents in Alameda. In October 1972, they moved to Merced to live with Maiy Jo’s brother, Lariy, and his wife, Carmella. On October 18, 1972, sometime after 1:30 p.m., Mary Jo disappeared. She has not been seen or heard from since. Substantial circumstantial evidence was introduced tending to show that appellant killed Maiy Jo and that his motive was to obtain custody of Rachel.
On October 22, 1972, three days after Maiy Jo’s disappearance, appellant was interviewed by Detective Sergeant Garibay and Officer Heitman of the Merced Police Department. Appellant waived his Miranda rights and agreed to talk with the officers. Appellant denied he had seen Mary Jo on the 18th. He appeared to be concerned about her disappearance and offered to cooperate with the-officers. When Sergeant Garibay asked appellant his whereabouts on the afternoon of October 18, appellant stated he could not recall or account for two hours—from 1:30 to about 3:30 p.m. Appellant also consented to a search of his van. The search revealed a blood spot about the size of a pencil eraser, a smear of blood on the rear door, several strands of hair, leather gloves and two knives. The blood smear had matted hair on it. During the search of the van, appellant appeared to be veiy nervous and asked, *234 “Could I have killed Mary Jo?” Officer Garibay said, “Yes, you could have killed Mary Jo.”
On November 8, 1972, Officers Garibay and Heitman interviewed appellant at his boarding house in Oakland. They testified that after receiving his consent to search his room they found some letters addressed to a girlfriend named “Penney.” Appellant, however, denied he had consented to a search of his premises.
Appellant was interviewed by Dr. Lunde, a psychiatrist at Stanford Medical School. The interviews took place at Dr. Lunde’s offices at Palo Alto on December 5, 7, 18 and 21, 1972. Appellant was taken to each interview by the Merced police officers, and each interview lasted for approximately one and one-half hours. While the record is silent as to the circumstances giving rise to the interviews, 1 Dr. Lunde testified that the original purpose of interviewing appellant was “to clear up an approximately two hour period of amnesia which Mr. Bennett said he had for the afternoon of October 18, 1972.”
At trial, Dr. Lunde was called as a prosecution witness to express an opinion that appellant had a dual motive for killing Maiy Jo—his concern for the raising of Rachel and his desire to obtain her custody. In the course of explaining the reasons for his opinion, Dr. Lunde testified to several incriminating statements by appellant during the interviews. For example, after repeated questioning by Dr. Lunde, appellant acknowledged that perhaps he had not suffered amnesia and suggested a conspiracy against him by Mary Jo’s family. He said that he hated Maiy Jo; that she shouldn’t live; that she was a bad housekeeper, a slut and an immoral woman. He further told Dr. Lunde that such “a terrible person ought not to live” and “ought not to be allowed to raise his child.” He expressed his feeling that Mary Jo and Rachel would be better off if Mary Jo were dead. Appellant also related to Dr. Lunde certain statements made to him by Maiy Jo, such as, “If you kill me you won’t get custody.” Appellant also told Dr. Lunde about two dreams he had *235 had approximately two weeks before Mary Jo’s disappearance. In the first dream he saw Mary Jo dead in a coffin. In the second dream he saw Rachel in a coffin, but he was able to lift her out of the coffin and declare that she was not dead. Dr. Lunde testified that most dreams represent “wish fulfillment.” He expressed the opinion that appellant’s dreams represented his wish that Mary Jo were dead and that he had to rescue Rachel from the evil influence of her mother.
Appellant timely objected to Dr. Lunde’s testimony on several grounds, one of which was “that Dr. Lunde was at the time [of the interviews] employed by the prosecution . .., and that his interview with the defendant was not prefaced by the necessary admonitions under Miranda.” In response, the prosecutor stated that appellant had been advised of his Miranda rights. Later, in further argument out of the presence of the jury, the prosecutor told the court: “This is a case where the court did not appoint the doctor, but where the defendant was advised of his constitutional rights by the doctor [and] after being fully advised agreed to talk with the doctor on four separate occasions.” Without any further inquiry or hearing, the trial judge overruled appellant’s objections.
During Dr. Lunde’s testimony before the jury, the prosecution asked the following question:
“Q. And did you advise Mr. Bennett of his Constitutional rights before proceeding on yoúr first interview? A. Yes, I did. We went over in some detail at the beginning of the first interview.”
Later, in Dr. Lunde’s testimony, the following took place: “Q. You saw him on four occasions, . . . ? A. Yes. Q. And in the first of these occasions you told him you were working for the district attorney’s office? A. Yes. Q. You said you were going to report—what you learned from him might be or could very well be reported to the authorities, did you not? A. Yes, I certainly did.”
Discussion
At the outset we observe that the trial court failed to properly adjudicate the admissibility of Dr. Lunde’s testimony concerning appellant’s incriminating statements. The timely
Miranda
objection imposed on the trial court a procedural duty to determine the existence or nonexistence of the preliminary fact, i.e., appellant’s waiver of his
*236
Miranda
rights, out of the presence of the juiy. (Evid. Code, §§ 310, 402, 405;
People
v.
Rowe
(1972)
Instead of adjudicating the Miranda question as required by Evidence Code section 405, the trial court apparently accepted the prosecutor’s bald assertion that appellant had been advised of his constitutional rights by Dr. Lunde and overruled the objection.
Regardless of the trial court’s procedural error, however, appellant has suffered no prejudice if the prosecution proved through the testimony of Dr. Lunde or other witnesses that appellant’s statements at the interviews were in fact preceded by an adequate waiver of his Miranda rights. Thus, as a reviewing court, we must independently examine the record to determine if the Miranda requirements were satisfied.
Miranda
v.
Arizona, supra,
Particularly applicable to the present case is the following: “Accordingly we hold that an individual held for interrogation must be clearly informed that he has the right to consult with a lawyer and to have the lawyer with him during interrogation under the system for protecting the privilege we delineate today. As with the warnings of the right to remain silent and that anything stated can be used in evidence against him, this warning is an absolute prerequisite to interrogation.
No amount of circumstantial evidence that the person may have been aware of this right will suffice to stand in its stead.
Only through such a warning is there ascertainable assurance that the accused was aware of this right.” (384 U.S. at pp. 471-472 [
This synopsis of Miranda demonstrates beyond question that the prosecution failed to meet its burden of proving Dr. Lunde properly advised appellant of his constitutional rights and that appellant knowingly and intelligently waived his rights. As far as the record shows, Dr. Lunde failed to advise appellant of his right to remain silent and his right to an attorney during the interviews; furthermore, no express waiver of any Miranda right is shown.
The question arises whether appellant’s waiver of his
Miranda
rights on October 22, 1972, some six weeks before his interviews with Dr. Lunde, can be carried over to insulate his statements to Dr. Lunde from
*238
constitutional attack. It is clear that subsequent statements by a defendant without
Miranda
warnings are nonetheless admissible upon a judicial finding that a prior adequate warning was given “within a reasonably contemporaneous period of time.”
(People
v.
Johnson
(1973)
Whether the prior
Miranda
warning is adequate depends upon the particular facts and circumstances of the case including the background, experience and conduct of the accused. (See
People
v.
Duren
(1973)
Respondent argues somewhat vaguely that, because appellant was a college graduate, and because he had been advised of his
Miranda
rights on October 22 and professed to cooperate with the police by waiving his rights and talking with them on October 22 and, later, on November 8th, Dr. Lunde’s “reminder” of his constitutional rights on December 5 is sufficient evidence from which an inference can be drawn
*239
that appellant fully understood his rights and knowingly, intelligently and voluntarily waived them at the time he talked with Dr. Lunde. The argument is without merit for several reasons: First, it is based on inferences from circumstantial evidence that tend to show only that appellant
may
have been aware of his rights when he talked with Dr. Lunde. As previously noted, such evidence cannot support a finding of waiver.
(Miranda
v.
Arizona, supra,
Third, there is a vast difference between a defendant talking to police officers in the cold and normally hostile atmosphere of a police station and talking to a psychiatrist in the comfortable environment of his office. Regardless of Dr. Lunde’s initial advice to appellant that whatever he said could be turned over to the authorities, it is apparent that during the six hours of interviews Dr. Lunde established a relationship of confidence with appellant; yet it is not clear that appellant fully understood and appreciated the nature of that relationship. Apart from any amnesia concerning the events of October 18, for appellant to have done what he was charged with doing, he obviously was suffering from severe mental and emotional problems; such a condition mandates clear and independent proof of compliance with the Miranda requirements before the interviews with Dr. Lunde.
In summary, the prosecution failed to meet its heavy burden of demonstrating appellant’s knowing and intelligent waiver of his
Miranda
*240
rights before his interviews with Dr. Lunde. Moreover, the error in admitting the incriminating statements must be deemed prejudicial. “. . . before a federal constitutional error can be held harmless, the court must be able to declare a belief that it was harmless beyond a reasonable doubt.”

v.
California
(1967)
The judgment is reversed.

Notes
Respondent argues that appellant agreed to be interviewed by Dr. Lunde in an attempt to throw suspicion away from himself. The only evidence which possibly supports such an inference is appellant’s cooperation on October 22 in answering police questions about Mary Jo’s disappearance and consenting to a search of his van, and the officers’ testimony that appellant consented to a search of his house in Oakland on November 8. The record is silent insofar as any testimony by appellant or the officers as to who requested the interviews with Dr. Lunde, the reason for the interviews, and whether appellant was coerced into agreeing to the interviews under threat of prosecution for Mary Jo’s murder if he did not consent thereto.
Evidence Code section 405 required the trial court to indicate which party had the burden of proof on the preliminary fact. This was of critical importance because of the rule that a
Miranda
waiver cannot be inferred from circumstantial evidence such as the fact that a defendant makes a statement to the police. (See
Miranda
v.
Arizona
(1966)
Respondent concedes that Dr. Lunde was acting in the capacity of a police agent and that the interviews were conducted in an atmosphere of a custodial interrogation. (See
