This case principally concerns the interrelated mandates of the state and federal constitutions that determine the admissibility of custodial confessions procured after a suspect was found at his home in the early hours of the morning
*153
and then invited to police headquarters. The defendant, Anthony S. Derrico, was indicted and convicted, after trial to a jury, of the crime of felony murder, in violation of General Statutes §§ 53a-54c and 53a-54a (c), in connection with the shooting death of Anne H. Moore during the course of a robbery or attempted robbery on Aрril 8, 1976, at the Howard Johnson’s Motel in Rocky Hill. Before trial, the defendant moved to suppress two confessions made to police during a custodial investigation at police headquarters. Although the trial court,
Shea, J.,
at that time ordered one of the statements suppressed in light of the failure of the police to have given the defendant complete warnings as required by
Miranda
v.
Arizona,
In his appeal, thе defendant challenges (1) the admission into evidence of certain statements admitting culpability; (2) the refusal of the trial court to require that a record be made of the grand jury proceedings or to permit counsel to be present during the grand jury proceedings; and (3) the charge to the jury concerning the requirement of proof beyond a reasonable doubt.
I
Because of its significance, we first address the defendant’s claim that the two confessions obtained by the police at police headquarters were improperly admitted into evidence at trial. The pertinent factual circumstances, as they appear from the transcripts of the trial and from Derrico’s motion to *154 suppress the confessions, supplemented by the trial court’s memorandum of decision on the motion to suppress, are as follows: On June 3, 1976, incident to an arrest on an unrelated charge, Connecticut state police officers searched the defendant’s car and located under the dashboard a .38 caliber handgun to which the defendant, after being advised of his full Miranda rights, admitted ownership. On June 18, 1976, at about 9:20 a.m., the state police received a ballistics report from the federal bureau of investigation linking the gun with the bullet recovered from the motel office where Anne H. Moore had been shot. On June 19, 1976, at about 6:15 a.m., acting solely on the basis of the ballistics report obtained nearly twenty-four hours earlier, Officer Massamura of the Rocky Hill police and Trooper Raposa of the Connecticut state police arrived, without an arrest warrant, at the defendant’s West Hartford home where he lived with his father. They found the defendant and invited him to accomрany them to the Hartford state police headquarters for questioning. He was not then told either that he was being arrested or that he was free to refuse to go to Hartford. The defendant did not object to accompanying the officers to the police station. While in the police car, en route to the Hartford state police barracks, the defendant was advised of two elements of the Miranda warnings: his rights to remain silent and to have counsel present during questioning. During the trip he was further advised that he would be free to leave if, upon arrival in Hartford, he chose not to speak.
Upon arrival at state police headquarters at about 6:45 a.m., the defendant was escorted into an interrogation room equipped with a recording machine. *155 The defendant was again told he was free to leave; was informed that his handgnn had been identified as the murder weapon; and was questioned about the incident at Howard Johnson’s. Incomplete Miranda warnings were given, 1 interrupted by the defendant’s objection to the reading. Thereafter, at around 7:15 a.m., but before the defendant had been fully advised of or had formally waived his Miranda rights, the defеndant admitted his involvement in the crime. This statement was unrecorded.' The interview continued, and, at approximately 8:07 a.m., nearly one and one-half hours after Der-rico’s arrival at the police barracks, the tape recorder was turned on and the defendant was read the complete Miranda warnings. 2 The defendant refused to sign the waiver form provided by the police as to each element of the Miranda warning, and the tape recorder was turned off. The defendant subsequently agreed to give a statement and the recorder was reactivated. The dеfendant, show *156 ing signs of being emotionally distraught, executed a waiver of his Miranda rights and confessed his role in the crime. While the defendant was in the process of making his statement, the tape recorder was turned off several times for unrecorded discussion. After the taping, the defendant, crying, crumpled the waiver form which was later found “all torn up” and which was produced at trial as several pieces of paper taped together.
The question of the admissibility of the two confessions, one obtained before and one after full reading of the Miranda warnings, was twice рresented to the trial court. In a motion to suppress before the trial had begun, the first confession was ruled inadmissible. Nonetheless, at trial, both confessions were admitted into evidence over the timely objection of the defendant with exceptions duly noted. The record does not disclose why the trial court reversed its earlier ruling. Since the state, however, in its brief concedes the inadmissibility of the first confession, we need not consider anything other than the second confession at this time.
The defendant argues the inadmissibility of the second confession on a variety of constitutional grounds. In reliance on the protection against self-incrimination contained in the fifth amendment to the United States constitution and article first, § 8 of the Connecticut constitution, and his right to due
*157
process of law under the fifth and fourteenth amendments to the United States constitution and article first, §§ 8 and 9 of the Connecticut constitution, the defendant maintains that the confession should have been excluded as involuntary. In reliance on the protection against unreasonable search and seizure contained in the fourth amendment to the United States constitution and article first, § 7 of the Connecticut constitution, the denial of which would violate his right to due process of law under the fifth and fourteenth amendments to the United States constitution and article first, §§ 8 and 9 of the Connecticut constitution, the defendant contends that the confession should have been excluded as the tainted fruit of an illegal arrest. It is clear under recent decisions of the United States Supreme Court that a confession that is found to be voluntary for purposes of the fifth amendment has met only a threshold requirement for fourth amendment analysis. With respect to the fourth amendment, the further test is whether there is so close a causal connection between an illegal arrest and a confession that the confession must be suppressed in order to deter similar police misconduct in the future and to protect the integrity of the courts.
Dunaway
v.
New York,
The defendant’s claim that the second confession should have been excluded as viоlative of the fourth *158 amendment to the United States constitution and article first, §§ 7 and 9 of the Connecticut constitution requires the determination of three subsidiary questions: (1) was the defendant arrested? (2) was the defendant’s arrest illegal? and (3) was the confession causally related to the defendant’s illegal arrest? Since we decide the first of these questions in the negative, we agree with the state that the confession was not wrongfully admitted.
The question whether the defendant was under arrest when he acceded to the request of the police officers to accompany them to police headquarters in Hartford is crucial to the defendant’s fourth amendment claims. If the defendant voluntarily went to Hartford with the police, there was then no coercive police conduct to invoke the exclusionary rules of
Payton
v.
New York,
“Precisely when an arrest occurs is a question of fact which depends on an evaluation of all the surrounding circumstances.
Sibron
v.
New York,
The defendant, in his argument that he was in fact arrested at his home in West Hartford, points to four factors that the record incontrovertibly establishes: he was picked up at his home in the early hours of the morning; the officers then had reason to know that he was a strong suspect with regard to a serious crime; the officers did not expressly advise him of his right not to come until he was in the police car on its way to Hartford; the officers attempted to administer
Miranda
warnings in the car, as if he were then in custody. The state’s
*161
argument to the contrary rests on the officers’ testimony that they had no intent to arrest the defendant at his home, would have permitted him to remain at home, and repeatedly advised him of his right to leave before serious questioning was begun at Hartford police headquarters. The trial court was entitled to give credence to the testimony of the police;
State
v.
Mitchell,
Admissibility of the confession with respect to the defendant’s claims under the fourth amendment to the United States constitution and article first, of the constitution of Connecticut does not resolve the defendant’s claims under the fifth and fourteenth amendments to the United States constitution and article first, § 8 of the Connecticut constitution. The confession, although free from the taint of an illegal arrest, must still meet the test of voluntariness established by
Rogers
v.
Richmond,
In this ease the defendant raises four claims concerning admissibility: (1) was the second confession itself given voluntarily? (2) was the second confession tainted by an earlier inadmissible confession? (3) was the confession procured in violation of his right to counsel? and (4) was the confession obtained in violation of his right to remain silent? The defendant would have us resolve all of these claims in the affirmative; we do not agree.
The trial court found that the state had sustained its burden of proving that the defendant’s taped confession was given voluntarily and was not the product of any threat, promise, or coercion; that the defendant fully understood his constitutional rights which were read to him by the officers just before the tape recording; and that he waived these rights knowingly and voluntarily as indicated on the tape and by his signature on the executed waiver form.
The issue of whether a confession is voluntary and admissible is, in the first instance, one of fact for determination by the trial court in the exercise of its legal discretion.
State
v.
Devine,

*163
640, 652,
“ ‘[T]he test of voluntariness is whether an examination of all the circumstances discloses that the conduct of “law enforcemеnt officials was such as to overbear [the defendant’s] will to resist and bring about confessions not freely self-determined . . . .”
Rogers
v.
Richmond,
We cannot say that, on the basis of the evidence before it, the trial court erred in concluding that the defendant had knowingly аnd voluntarily waived his
Miranda
rights and that consequently his taped confession was voluntarily given. The defendant’s emotional state, his hesitancy to initial the official form waiving his
Miranda
rights, and his subsequent mutilation of the waiver form do not, in light of the other credible evidence before the court, compel the conclusion that his waiver was not
*164
knowing, intelligent and voluntary, or that his confession was not “the product of an essentially free and unconstrained choice” and therefore coerced.
Culombe
v.
Connecticut,
supra, 602;
State
v.
Staples,
supra, 408. The entire transaction in the interrogation room occupied some еighty minutes. There was no evidence that the defendant requested an attorney or indicated a desire to terminate the interview. The defendant was provided with coffee. There was no indication that he was under the influence of alcohol or drugs, or that he was mentally or emotionally handicapped. Although there was police testimony that when the defendant indicated his unwillingness to sign the waiver
form
the tape recording was turned off and then reactivated when he executed the waiver and agreed to give a statement, the defendant does not сlaim on appeal that he was physically restrained or abused, that physical or psychological force was used upon him, or that any threats, promises, or offers were made. This case is therefore, on its facts, readily distinguishable from the overbearing circumstances of
Rogers
v.
Richmond,
supra, and
Culombe
v.
Connecticut,
supra. Cf.
State
v.
Staples,
supra, 400;
State
v.
Traub,
The defendant contends that his reluctance to sign the
Miranda
waiver form manifested so clear an exercise of his right to remain silent as to invoke his fifth amendment privilege to cut off further questioning.
Michigan
v.
Mosley,
On the basis of the record before us, we conclude that there was sufficient evidence before the trial court to sustain its conclusion that the defendant was advised of his constitutional rights, executed a valid waiver, and confessed voluntarily. Viewing the totality of the circumstances, we сannot say that the free will of the defendant was overborne. See
United States
v.
Washington,
Nor on our review of the record can we say that the trial court erroneously concluded that the defendant’s taped confession was not tainted incurably by the prior unrecorded statement of involvement. The defendant argues that his confession should have been suppressed because he “let the cat out of the bag” by his earlier inculpatory statement, that his taped confession was the product of the earlier statement. We do not agree.
As we stated in
State
v.
Rosa,
Two factors are of primary importance in assessing the voluntariness of a subsequent statement: (1) the lapse of time between the invalid confession and the later statement and (2) whether the confessor has been confined during that period. State v. Darwin, supra, 425-26. These factors do not, however, provide a categorical answer to the ultimate question of voluntariness, which rеquires examination of the totality of the relevant facts. As the court stated in Tanner v. Vincent, supra, 937, if the defendant did let the cat out of the bag, “this *167 was only one factor bearing on the disputed issue of the voluntariness of the later, fully advised statement.”
The impact of the defendant’s prior indication of involvement was a fact among others to be considered by the trial court in determining whether the defendant’s taped confession was a voluntary utterance; it did not conclude the issue. The first “confession” was only a general acknowledgment of involvement in the crime, whereas the second confession was detailed. The failure of the police immediately to inform the defendant of his complete
Miranda
rights was the result of the defendant’s own objections and resistance. The trial court could reasonably have viewed as less pernicious a prior statement whose inadmissibility was premised on the failure of the police to fulfill completely the prophylactic requirements of
Miranda
v.
Arizona,
than a statement involuntarily extracted by coercion.
Michigan
v.
Tucker,
The defendant additionally urges suppression of the confession under the sixth amendment to the United States constitution and article first, § 8 of the constitution of Connecticut on the ground that he was denied the right to counsel. The defendant claims that he was represented by counsel appointed on an unrelated matter, that this fact was known to the police, and that he did not knowingly, intelligently and voluntarily waive his right to that counsel.
*168
A statement made by a defendant during the course of a custodial interrogation is ordinarily admissible into evidence only if his counsel is present or if he knowingly, intelligently and voluntarily waives his right to counsel.
State
v.
Moscone,
The defendant’s remaining claim with regard to the admissibility of his confession is that he was not informed of his right to stop answering questions at any time. The operative language in
Miranda
v.
Arizona
on which the defendant relies states: “Once warnings have been given the subsequent procedure is clear. If the individual indicates in any manner, at any time prior to or during questioning, that he wishes to remain silent, the interrogation must cease.”
Miranda
v.
Arizona,
In summary, our еxamination of the various arguments raised concerning the admissibility of the second confession as the defendant’s voluntary act persuades us that the trial court’s conclusion permitting its introduction into evidence was not in error.
II
The defendant’s claims as to impropriety in the grand jury proceedings arise out of motions filed, after his arrest, with regard to the then forthcoming grand jury concerning his possible indictment. He
*170
asked that a stenographic record and transcript be made, and that he be permitted to be accompanied by counsel at the grand jury proceedings. Both motions were denied, and these rulings have been assigned as errors upon this appeal. In light of our recent opinion in
State
v.
Piskorski,
in
The defendant’s final claim charges that the trial court,
D. Shea, J.,
erred in instructing the jury with respect to the doctrine of the requirement of proof beyond a reasonable doubt. The defendant focuses upon that part of the charge in which the court defined a reasonable doubt as “one for which you can, in your own mind, conscientiously give a reason.” The defendant contends that this charge, to which timely exception was taken, improperly lessened the state’s burden оf having to prove guilt beyond a reasonable doubt, and erroneously cast upon the defendant the burden of furnishing reasons for acquittal, and hence violated the defendant’s right to due process of law under the fifth and fourteenth amendments to the United States constitution and article first, §§ 8 and 9 of the Connecticut constitution. See
Mullaney
v.
Wilbur,
As we have often stated, the test to be applied to any part of a charge is whether the charge as a whole presents the case to the jury so that no injustice will be done.

v.

There is no error.
In this opinion the other judges concurred.
Notes
It is not clear what elements of the Miranda warnings were read to Derrieo at this point. At trial, Trooper Raposa testified: “After we discussed some of the information, I then attempted to read Mr. Derrieo Ms Miranda warnings. I got, maybe, two or three lines into it, and he told me to stop, that he didn’t want to be arrested. And I told Mm, just because I was reading him his warnings, that didn’t mean that he was going to be arrested. And he started crying at one point, sobbing.
“I attempted to read him the warnings again, and the same thing, I got two or three lines out, and he told me to stop agаin. I think this occurred on three occasions. And, on the third occasion, as I was either three or four lines through the warnings, he then told me he was involved in the murder at Rocky Hill.”
At trial, Trooper Raposa testified that before the defendant “signed or initialed anything” he was read the following warning: “Warning: The constitution requires that I inform you of your rights. Tou have the right to remain silent. If you talk to any police officer, anything you say can and will be used against you in court. You have the right to consult with a lawyer before you are questioned and may have him with you during questioning. If you cannot afford a lawyer, one will be appointed for you, if you wish,
*156
before any questioning. If you wish to answer questions, you have the right to stop answering at any time, if you wish, to talk to a lawyer and may have him with you during any further questioning.” This language satisfies the requirements of
Miranda
v.
Arizona,
Section 110.1 of the American Law Institute, Model Code of PreArraignment Procedure entitled Bequests for Cooperation by Law Enforcement Officers, states in pertinent part:
“(3) warning to persons asked to appear at a police station. If a law enforcement officer acting pursuant to this Section requests any person to come to or remain at a police station, prosecutor’s office or other similar place, he shall take such steps as are reasonable under the circumstances to make clear that there is no legal obligation to comply with such request.” An earlier version of this section, substantively virtually identical, was cited in Dunaway v. New York,442 U.S. 200 , 217,99 S. Ct. 2248 ,60 L. Ed. 2d 824 (1979).
Section 120.5, entitled Circumstances Implying Arrest, states in pertinent part:
“(2) requests to appear at police station. If a law enforcement officer, pursuant to Section 110.1, requests any person to come to or remain at a police station, prosecutor’s office, or other similar place, and does not take such steps as are reasonable under the circumstances to make clear that no legal obligation exists to comply with such request, such person shall be accorded all the rights and protections afforded to arrested persons by this Code.”
On the question of what is meant by a reasonable doubt, the court charged the jury as follows: “A reasonable doubt is not such a doubt as may be raised by one questioning for the sake of raising a doubt. It is not a surmise or a guess or a conjecture. It is not hesitation springing from feelings of sympathy or pity for the accused or members of his family or other persons who might in any way be affected by your verdict. A reasonable doubt is one founded upon the evidence; one which grows out of the evidence or the lack of evidence in the case. It is one for which you can, in your own mind, conscientiously give a reason. A reasonable doubt is a square and honest doubt, grounded on reason; one which appeals to reason. If the facts you may find proven can reasonably be explained in any other way than that the accused is guilty, you must, of course, render your verdict in his favor.”
