. OPINION OF THE COURT
NIX, Justice.This appeal again raises the troublesome issue as to when an accused under the age of 18 years may effec*495tively waive his constitutional rights prior to custodial interrogation.1 For the reasons set forth hereinafter we are constrained to reverse the judgments of sentence and award the grant of a new trial.
On November 7, 1974, appellant, Barry Smith, a 17-year-old youth, fired six shots in the direction of another youth who was a member of a rival gang. The bullets missed the intended victim and struck Crystal Loney and Batina Brooks, two innocent bystanders, who were in the vicinity at the time of the shooting. Crystal, who was age 14 at the time of the shooting, died from a gunshot wound to the head several hours later. Although Batina was shot in the arm and head she fortunately recovered. Appellant was subsequently arrested, tried and convicted of murder of the first degree, possession of an instrument of crime, and carrying a firearm on public streets. Following a denial of post-trial motions, Smith was sentenced to life imprisonment under the murder indictment and received a sentence of one to two years for each of the weapon charges, both to run concurrently with the life sentence. This direct appeal followed.2
Appellant argues that the inculpatory statement elicited during custodial interrogation following his arrest should have been suppressed because the record does not reflect an effective waiver of his Miranda3 *rights. After an analysis of this Court’s recent cases relating to ju*496venile waivers prior to custodial interrogation, the trial judge concluded:
“Under the guidelines of state and federal appellate cases, the likelihood that a young defendant did not understand the import and consequences of his confession does not warrant the exclusion of the statement where all the proprieties have been observed. This Court has grave misgivings that Barry Smith or any other juvenile of similar age, I.Q. and background, could knowingly, intelligently and competently waive his constitutional rights. However, all of the formal due process requirements were observed. Under the law in Pennsylvania at the time of this writing, there is no authority to exclude the statement.” (Emphasis added).
Before turning to the merits of this appeal, we deem it necessary to comment upon the above-quoted observation of the trial court since, in our judgment, it touches upon the heart of the controlling considerations involving waiver of substantial constitutional rights. In our view, due process requires that a waiver by a youthful offender is effectuated only when it has been shown that the minor comprehended the full significance of the panoply of rights that protects him during custodial interrogation. We have insisted that the Commonwealth bear the burden of proving a knowing waiver. Commonwealth v. Hailey, 470 Pa. 487, 368 A.2d 1261 (filed January 28, 1977); Commonwealth v. Webster, 466 Pa. 314, 353 A.2d 372 (1976); Commonwealth v. Smith, 465 Pa. 310, 350 A.2d 410 (1975); Commonwealth v. McCutchen, 463 Pa. 90, 343 A.2d 669 (1975); Commonwealth v. Starkes, 461 Pa. 178, 335 A.2d 698 (1975); Commonwealth v. Roane, 459 Pa. 389, 329 A.2d 286 (1974). In Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L. Ed.2d 694 (1966), the United States Supreme Court in *497setting forth the required procedures for police interrogation of suspects warned:
The requirement of warnings and waiver of rights is a fundamental with respect to the Fifth Amendment privilege and not simply a preliminary ritual to existing methods of interrogation.
Id. at 476, 86 S.Ct. at 1629.4
We cannot accept the implication of the trial judge’s statement, that the inquiry as to the effectiveness of the waiver of a minor is satisfied because the formal prerequisites have been met, as long as there is reason to question whether the minor, in fact, has comprehended his situation.
We have devoted special attention to the observation of the learned trial judge because her concern capsulizes that which motivated a majority of this Court to seek a technique which would avoid the warning of a juvenile becoming a mere ritual wherein the effect of actual comprehension is ignored. Because of the unique disadvantage in the custodial interrogation process of the youthful accused due to his immaturity,5 it was recognized that merely a consideration of the fact of youth in the totality of the circumstances formulation, Commonwealth v. *498Fogan, 449 Pa. 552, 296 A.2d 755 (1972); Commonwealth v. Taylor, 449 Pa. 345, 296 A.2d 823 (1972); Commonwealth v. Moses, 446 Pa. 350, 287 A.2d 131 (1971); Commonwealth v. Darden, 441 Pa. 41, 271 A.2d 257 (1970); Commonwealth v. Taper, 434 Pa. 71, 253 A.2d 90 (1969), was inadequate to insure that a juvenile’s waiver was indeed a knowing one.
In a series of our decisions beginning with Commonwealth v. Roane, supra,6 we announced that the administering of Miranda warnings to a juvenile, without providing an opportunity to that juvenile to consult with a mature, informed individual concerned primarily with the interest of the juvenile, was inadequate to offset the disadvantage occasioned by his youth. The new rule appreciates that the inexperience of the minor affects not only his or her ability to understand the full implication and consequences of the predicament but also renders the judgment inadequate to assess the spectrum of considerations encompassed in the waiver decision.7 It was therefore reasoned that the impediment of immaturity can only be overcome where the record establishes that the youth had access to the advice of an attorney, parent, or other interested adult and that the consulted adult was informed as to the constitutional rights available to the *499minor and aware of the consequences that might follow the election to be made. See, Commonwealth v. Starkes, supra.
Reviewing the facts of the instant appeal, it is apparent that this juvenile did not receive the requisite protections envisioned in our recent case law. The testimony of the suppression hearing established that within hours of the incident appellant became a suspect in the shooting. The police arrived at appellant’s home at 4:15 A.M. on November 8, 1974, and were admitted to the premises by appellant’s father, Jack Miller. The police and Miller then proceeded to an upstairs bedroom where appellant was awakened and told to dress. At this time Smith was taken into custody and read the first side of the police interrogation card which contained the Miranda warnings, but there was no inquiry whether the suspect or his father understood that which had been read to him. Smith was taken downstairs and the police informed Mr. Miller that he could accompany his son to the Police Administration Building, but the father declined to do so.8
Appellant arrived at police headquarters and was placed in an interrogation room until 5:30 A.M. when he was again warned. This time the card was read in its entirety and the minor gave monosyllabic responses to the questions which were posed. Smith then proceeded to participate in the interrogation during which he made inculpatory statements which were later reduced to writing. The interviews were concluded by 7:50 A.M.
The Commonwealth contends that because the parent heard the warnings but declined to accompany his son to the police station for questioning, the requirement of *500providing the accused with the “opportunity for adult consultation” had been met. We disagree.
In Roane, we first articulated the concept that an attempted waiver of the Fifth and Sixth Amendment rights during custodial interrogation will not be considered as being effective absent a showing that the minor “had access to the advice of a parent, attorney or other adult who was primarily interested in his welfare.” Id., 459 Pa. at 394, 329 A.2d at 288. It was never the intention to exclude the requirement of interest simply because the consulting adult was a parent of the minor.9 To the contrary, it was assumed that the relationship would assure the requisite concern for the welfare of the minor. However, that assumption does not justify the creation of an irrebuttable presumption of interest by a parent. Where, as here, the disinterest of the parent is graphically demonstrated, it is clear that Mr. Miller was not the interested adult envisioned in the rule. If the adult is one who is not concerned with the interest of the minor, the protection sought to be afforded is illusory and the procedure fails to accomplish its purpose of offsetting the disadvantage occasioned by the immaturity.
Not only does Mr. Miller fail to qualify as an adult interested in the welfare of Barry, he also cannot be said, on this record, to have been an informed adult. In Starkes, we stated that the record must establish that the consulting adult was aware of the rights possessed by a person in the situation of the accused. If the available adult was as unaware as the suspect himself, then obviously the procedure would be meaningless.
*501Where an informed adult is present the inequality of the position of the accused and police is to some extent neutralized and due process satisfied. However, where the adult is ignorant of the constitutional rights that surround a suspect in a criminal case and exerts his or her influence upon the minor in reaching the decision, it is clear that due process is offended. An uninformed adult present during custodial interrogation presents an even greater liability. The minor in such a situation is given the illusion of protection, but is in fact forced to rely upon one who is incapable of providing the advice and counsel needed in such a situation.
Unless we require police officers to also advise parents, who are in the position to counsel minor suspects during custodial interrogation, we will not only fail to assure the full benefits sought to be attained by this type of counseling but we will also increase the likelihood that the suspect will be misinformed as to his rights.
Id. 461 Pa. at 188, 335 A.2d at 703 (footnote omitted).
Although the warnings were read to appellant in the presence of Mr. Miller, there was no attempt by the police officers to ascertain whether Mr. Miller had even directed his attention to what was being said, much less whether he understood the significance of the warnings. Where an adult defendant is being advised of his rights, our cases require that the police officials must make a reasonable effort to ascertain that the accused understands the warnings that have been read to him. Commonwealth v. Bullard, 465 Pa. 341, 350 A.2d 797 (1976); Commonwealth v. Ritter, 462 Pa. 202, 340 A.2d 433 (1975); Commonwealth v. Scoggins, 451 Pa. 472, 304 A.2d 102 (1973); Commonwealth v. Stafford, 451 Pa. 95, 301 A.2d 600 (1973); Commonwealth v. Ponton, 450 Pa. 40, 299 A.2d 634 (1972). There is no reasonable basis to conclude that this same requirement is not also necessary *502to insure that the consulting adult is in fact aware of the rights possessed by the minor.
Traditionally, we have held that the burden rests upon the Commonwealth to establish an effective waiver. Commonwealth v. Boone, 467 Pa. 168, 354 A.2d 898 (1975); Commonwealth v. Romberger, 464 Pa. 488, 347 A.2d 460 (1975); Commonwealth v. Goodwin, 460 Pa. 516, 333 A.2d 892 (1975); Commonwealth v. Ewell, 456 Pa. 589, 319 A.2d 153 (1974); Commonwealth v. Ravenell, 448 Pa. 162, 292 A.2d 365 (1972); Commonwealth v. Taper, supra. As a corollary to this principle we have held that the prosecution must not only demonstrate that the warnings were given but also that the accused manifested an understanding of these rights. Commonwealth v. Bullard, supra; Commonwealth v. Ritter, supra; Commonwealth v. Scoggins, supra; Commonwealth v. Stafford, supra; Commonwealth v. Ponton, supra. Applying this fundamental principle to the instant situation it necessarily follows that the Commonwealth must establish on the record that the adult did in fact comprehend the rights possessed by the minor. Since there is no evidence in this case to establish such a finding, this fact, of itself, justifies the conclusion that the asserted waiver is ineffective.
Lastly, this alleged waiver is also ineffective because the minor was not in fact provided an opportunity for consultation. The Commonwealth’s position erroneously focuses upon the opportunity afforded the adult. They assumed that the parent’s disinterest can be translated into a waiver by a minor. This assumption completely misconstrues both the Fifth and Sixth Amendment privileges and the objectives sought to be achieved by our case law. These rights are personal to the accused and therefore may only be waived by him, not the adult. Providing an opportunity for consultation with an adult seeks to insure that the juvenile is provided a means by which he can make an informed choice with respect to *503his rights.10 Here, the opportunity to confer was denied because of Mr. Miller’s unilateral decision not to participate.
The factual situation posited in this appeal is clearly distinguishable from that presented in Commonwealth v. McFadden, 470 Pa. 604, 369 A.2d 1156 (filed January 1977). McFadden was arrested at or about 4:30 A.M. at his residence. After being informed of his Miranda rights in the presence of his mother,11 he was then handcuffed to a chair and left with his mother in the living room of their residence for a period in excess of ten minutes while the officers searched the home. During this period of time the mother and son were allowed to freely converse out of the hearing of the officers. Under those facts, the majority of this Court held that the opportunity to consult with an interested adult had been provided.12
The facts of the instant case are more similar to our recent opinion in Commonwealth v. Gaskins, 471 Pa. 238, 369 A.2d 1285 (filed February 28, 1977), wherein we held that an opportunity was not provided for consultation. In Gaskins, there was some testimony to indicate that appellant’s mother was told, prior to his departure for the Police Administration Building, that she could accompany him. The police testified that she declined this offer because of the need to care for the younger chil*504dren at home. The police officers also testified that she was given a phone number where her son could be reached at the Police Administration Building. However, the mother made no attempt to contact her son either prior to or during the interrogation. The Court held that even accepting this testimony, the circumstances nevertheless did not meet the requirement that a minor be provided an opportunity to consult.
The McFadden case is distinguishable from the facts of Gaskins and the instant appeal in that Mrs. McFadden and her son were in fact given a period of time to discuss the situation between them. In Gaskins and in this case no such opportunity was afforded. In Gaskins the mother declined to accompany her son because of her responsibility to the other children at home. Here appellant was effectively prevented from a meaningful consultation because of his “father’s” indifference. It is therefore clear that the similarity to the Gaskins factual situation and the dissimilarity to McFadden mandate the conclusion that the Gaskins rationale be employed here.
Under our formulation, failure by the Commonwealth to establish either the adult was one interested in the welfare of the juvenile accused, that the adult was aware of the rights of the accused, or that the minor had an opportunity to consult, would justify the conclusion that the purported waiver was ineffective. In this instance, the Commonwealth did not establish any of the three pre-requisites necessary to prove waiver. We are therefore constrained to conclude that the statement should have been suppressed.
The judgments of sentence are reversed and a new trial awarded.
Former Chief Justice JONES took no part in the consideration or decision of this case. MANDEBINO, J., joined the opinion of the Court and filed a concurring opinion. *505POMEROY, J., filed a dissenting opinion in which EAGEN, C. J., joined.. Appellant has also raised constitutional objections as to the imposition of a life sentence for a minor upon a conviction of murder of the first degree. In view of our disposition we need not consider or attempt to resolve this issue.
. Jurisdiction of the murder conviction is pursuant to the Appellate Court Jurisdiction Act, Act of July 31, 1970, P.L. 673, No. 223, art. II, § 202(1), 17 P.S. § 211.202(1) (Supp. 1976-77). The weapons convictions were appealed to the Superior Court and certified to this Court for consolidation and consideration.
. Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966).
. The thrust in Miranda was directed to the adult suspect. Obviously our need for scrutiny to be certain that the subject fully comprehends his rights is increased where the court is considering the waiver of an immature suspect.
. “[The juvenile defendant] cannot be compared with an adult in full possession of his senses and knowledgeable of the consequences of his admissions. He would have no way of knowing what the consequences of his confession were without advice as to his rights — from someone concerned with securing him those rights — and without the aid of more mature judgment as to the steps he should take in the predicament in which he found himself. A lawyer or an adult relative or friend could have given the petitioner the protection which his own immaturity could not. Adult advice would have put him on a less unequal footing with his interrogators.

A discussion of these and other authorities on this subject can be found in Comment, Pennsylvania Supreme Court Review, 1975 (Juvenile Miranda Waiver), 49 Temp.L.Q. 558, 704 (1976).
. At the suppression hearing, Miller testified that he neither attempted to determine his son’s whereabouts nor to obtain counsel following the arrest. Instead, he went to work and returned home about 4:35 P.M. in accordance with his usual routine.
. It is not clear from the record the exact nature of the relationship between Mr. Miller and Barry Smith. Although he is referred to as the father, it is not clear whether he is the natural father, adoptive father or stepfather. In Mr. Miller’s testimony, he merely stated that he was the father and that his wife, Mrs. Miller, was the stepmother. No explanation is given why Barry has a different surname.
. Under these facts, we need not reach the question of whether, if given the opportunity to consult with an interested, concerned and informed adult, a minor would be permitted to decline the offer and thereafter make an effective waiver. See, Commonwealth v. Webster, 466 Pa. 314, 326 n.5, 353 A.2d 372, 378 n.5 (1976).
. In this case it appears that not only were the warnings read but the police made a reasonable effort to ascertain that they were understood. Additionally, the police advised mother and son of the nature of the charges and the name and the residence of the victim.
. In McFadden, no challenge was raised as to the interest of the parent. Additionally, Mrs. McFadden did follow her son to the Police Administration Building and also attempted to secure counsel for him.
