OPINION OF THE COURT
PAPADAKOS, Justice.
Presented for consideration as the main issue in this appeal is whether our jurisprudence encompasses a good faith exception to the requirement of probable cause to support an application for the installation of pen registers. Because we hold that no such exception exists as yet in this Commonwealth, as based on these facts, we reverse the Superior Court and reinstate the decision of the suppression court disallowing all of the telephone evidence. We also determine as part of this analysis that the installation of pen registers must be supported by probable cause.
The criminal charges against the Appellants grew out of an investigation by the District Attorney of Philadelphia into organized illegal gambling operations. Based on confidential information, the authorities determined that the home of Appellant, Richard Mastro, was being used to conduct these operations over his phone. A court order issued at the request of the police authorized the Bell Telephone Company to install a pen register device on Mastro’s line.1 A separate confidential tip led to a second [409]*409order to place a pen register on the telephone line of Appellant, Nicholas DeStefano. Information obtained through the Mastro pen register led police to suspect Jerry DiJoseph, and his line also was subjected to a pen register based on probable cause.2 Subsequently, court-authorized wiretaps then were installed on all three lines in order to record criminal conversations. Each wiretap application was supported by a separate affidavit stating probable cause. These investigations culminated in the issuance of search and seizure warrants for twenty-three locations, including each Appellant’s residence. Police seized physical evidence of corrupt organizations and illegal gambling. In December, 1983, Appellants were charged with gambling offenses (lotteries, gambling, pool selling and bookmaking), conspiracy, and violations of the Corrupt Organization Act. Pursuant to pre-trial motions, the suppression court ruled that the Commonwealth lacked probable cause for the installation of the pen registers and, therefore, all evidence produced thereby, including wiretapped material seized by the police, was suppressed.
In a split decision, however, the Superior Court reversed on several grounds. First, it concluded that our law required probable cause for the installation of pen registers. Second, in spite of that requirement, the Commonwealth still was entitled to a good faith exception to the exclusionary rule, thereby allowing the evidence gained from the use of the pen registers under the facts of this case. Third, even without a good faith exception to the use of the pen registers, the separate wiretaps installed on the telephones of Mastro and DeStefano were independently reliable so as to confirm the existence of probable cause as to the evidence gained from those defendants.
[410]*410Adoption of the good faith exception rule by the Superior Court stemmed from a time-lag conflict over governing case law. At the time when all the pen registers were placed in 1983, the view regarding the need for a prior finding of probable cause to use pen registers was embodied in Smith v. Maryland, 442 U.S. 735, 99 S.Ct. 2577, 61 L.Ed.2d 220 (1979), which held that under federal law the use of a pen register was not a search under the Fourth and Fourteenth Amendments and that probable cause was not required.3 Four years later, however, our Superior Court decided Commonwealth v. Beauford, 327 Pa.Superior Ct. 253, 475 A.2d 783 (1984), allocatur denied, 508 Pa. 319, 496 A.2d 1143 (1985), which held that Article 1, section 8 of the Pennsylvania Constitution was offended by the installation of a pen register device without probable cause to support the application — a rejection of the federal standard. The Superior Court also held that Beauford applies retroactively, thereby controlling the instant case.
Drawing upon the suppression record, the Superior Court concluded further that “the orders authorizing installation and use of pen registers were not based upon findings of probable cause.” The suppression judge “made no findings before issuing orders authorizing installation of the pen registers in question. The orders do not suggest that Judge Conroy ever considered whether probable cause existed.” Commonwealth v. Melilli, et al, 361 Pa.Superior Ct. 429, 438-439, 522 A.2d 1107, 1111 (1987).
At the urging of the Commonwealth, nevertheless, the Superior Court approved the convictions by reading into our law the good faith exception doctrine of federal law announced in United States v. Leon, 468 U.S. 897, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984), and Massachusetts v. Sheppard, 468 U.S. 981, 104 S.Ct. 3424, 82 L.Ed.2d 737 (1984). The Superior Court’s application of that doctrine to the case under review here is based on the following rationale:
[411]*411Suppression of the evidence obtained by the installation of the pen registers in the instant case cannot further the purposes of the exclusionary rule. At the time when the pen registers were installed, existing law explicitly told law enforcement officials that the use of pen registers did not constitute a search. Pursuant to the Constitution of the United States, according to Supreme Court interpretation, the use of pen registers did not require a prior showing of probable cause. See: Smith v. Maryland, supra. According to the law then in effect, therefore, law enforcement agencies were not required to obtain a court order or warrant in order to install and make use of a pen register. Nevertheless, in order to comply with telephone company requirements, police in the instant case went further than the law required and requested from a neutral magistrate an order authorizing installation of pen registers. The magistrate, who also acted pursuant to existing law, issued an order authorizing the use of pen registers without a showing of probable cause. It was not until later that the Superior Court, applying principles of state constitutional law, outlawed the use of pen registers without a prior showing of probable cause. It seems clear, therefore, that the use of pen registers by law enforcement authorities was accomplished in good faith, in accordance with statutory authority in the Commonwealth of Pennsylvania, and consistently with procedure explicitly approved by the Supreme Court of the United States. To suppress evidence obtained under these circumstances would not further any of the purposes intended to be served by the exclusionary rule. Indeed, to deprive the Commonwealth of the use of evidence obtained in good faith and in accordance with then existing law as determined by the highest court in the land, would not only fail to serve the purposes of the exclusionary rule but would tend to defeat a substantial public interest in law enforcement. Therefore, we agree with the Commonwealth that an exception to the exclusionary rule must be created which has application narrowly to situations in which law enforcement officials [412]

OPINION OF THE COURT
PAPADAKOS, Justice.
Presented for consideration as the main issue in this appeal is whether our jurisprudence encompasses a good faith exception to the requirement of probable cause to support an application for the installation of pen registers. Because we hold that no such exception exists as yet in this Commonwealth, as based on these facts, we reverse the Superior Court and reinstate the decision of the suppression court disallowing all of the telephone evidence. We also determine as part of this analysis that the installation of pen registers must be supported by probable cause.
The criminal charges against the Appellants grew out of an investigation by the District Attorney of Philadelphia into organized illegal gambling operations. Based on confidential information, the authorities determined that the home of Appellant, Richard Mastro, was being used to conduct these operations over his phone. A court order issued at the request of the police authorized the Bell Telephone Company to install a pen register device on Mastro’s line.1 A separate confidential tip led to a second [409]*409order to place a pen register on the telephone line of Appellant, Nicholas DeStefano. Information obtained through the Mastro pen register led police to suspect Jerry DiJoseph, and his line also was subjected to a pen register based on probable cause.2 Subsequently, court-authorized wiretaps then were installed on all three lines in order to record criminal conversations.

Third, even without a good faith exception to the use of the pen registers, the separate wiretaps installed on the telephones of Mastro and DeStefano were independently reliable so as to confirm the existence of probable cause as to the evidence gained from those defendants.
[410]*410Adoption of the good faith exception rule by the Superior Court stemmed from a time-lag conflict over governing case law. At the time when all the pen registers were placed in 1983, the view regarding the need for a prior finding of probable cause to use pen registers was embodied in Smith v. Maryland, 442 U.S. 735, 99 S.Ct. 2577, 61 L.Ed.2d 220 (1979), which held that under federal law the use of a pen register was not a search under the Fourth and Fourteenth Amendments and that probable cause was not required.3 Four years later, however, our Superior Court decided Commonwealth v. Beauford, 327 Pa.Superior Ct. 253, 475 A.2d 783 (1984), allocatur denied, 508 Pa. 319, 496 A.2d 1143 (1985), which held that Article 1, section 8 of the Pennsylvania Constitution was offended by the installation of a pen register device without probable cause to support the application — a rejection of the federal standard. The Superior Court also held that Beauford applies retroactively, thereby controlling the instant case.
Drawing upon the suppression record, the Superior Court concluded further that “the orders authorizing installation and use of pen registers were not based upon findings of probable cause.” The suppression judge “made no findings before issuing orders authorizing installation of the pen registers in question. The orders do not suggest that Judge Conroy ever considered whether probable cause existed.” Commonwealth v. Melilli, et al, 361 Pa.Superior Ct. 429, 438-439, 522 A.2d 1107, 1111 (1987).
At the urging of the Commonwealth, nevertheless, the Superior Court approved the convictions by reading into our law the good faith exception doctrine of federal law announced in United States v. Leon, 468 U.S. 897, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984), and Massachusetts v. Sheppard, 468 U.S. 981, 104 S.Ct. 3424, 82 L.Ed.2d 737 (1984). The Superior Court’s application of that doctrine to the case under review here is based on the following rationale:
[411]*411Suppression of the evidence obtained by the installation of the pen registers in the instant case cannot further the purposes of the exclusionary rule. At the time when the pen registers were installed, existing law explicitly told law enforcement officials that the use of pen registers did not constitute a search. Pursuant to the Constitution of the United States, according to Supreme Court interpretation, the use of pen registers did not require a prior showing of probable cause. See: Smith v. Maryland, supra. According to the law then in effect, therefore, law enforcement agencies were not required to obtain a court order or warrant in order to install and make use of a pen register. Nevertheless, in order to comply with telephone company requirements, police in the instant case went further than the law required and requested from a neutral magistrate an order authorizing installation of pen registers. The magistrate, who also acted pursuant to existing law, issued an order authorizing the use of pen registers without a showing of probable cause. It was not until later that the Superior Court, applying principles of state constitutional law, outlawed the use of pen registers without a prior showing of probable cause. It seems clear, therefore, that the use of pen registers by law enforcement authorities was accomplished in good faith, in accordance with statutory authority in the Commonwealth of Pennsylvania, and consistently with procedure explicitly approved by the Supreme Court of the United States. To suppress evidence obtained under these circumstances would not further any of the purposes intended to be served by the exclusionary rule. Indeed, to deprive the Commonwealth of the use of evidence obtained in good faith and in accordance with then existing law as determined by the highest court in the land, would not only fail to serve the purposes of the exclusionary rule but would tend to defeat a substantial public interest in law enforcement. Therefore, we agree with the Commonwealth that an exception to the exclusionary rule must be created which has application narrowly to situations in which law enforcement officials [412]*412have acted (1) in good faith; (2) in reasonable reliance upon a procedure expressly sanctioned by existing judicial decisions; (3) pursuant to authorization obtained from a neutral magistrate. Because those prerequisites have been met in the instant case, we reverse the orders suppressing the evidence obtained by the use of the pen registers.
We also reverse the order suppressing the evidence obtained through the telephone intercepts and the physical evidence seized pursuant to the search warrants. The suppression court’s order was based upon its conclusion that absent the pen register evidence, the affidavits in support of the wiretap applications and search warrants were insufficient to establish probable cause. However, in light of our holding that the pen register evidence should not have been suppressed, it was unnecessary to discount that evidence when determining the existence of probable cause.
We first address the issue of whether Beauford was properly decided by the Superior Court. The Beauford court held that a pen register cannot be utilized by law enforcement authorities without an order based on probable cause, and we agree fully with that conclusion. The decision constituted an express rejection of federal law which, as already noted above in reference to Smith v. Maryland, held that the use of a pen register was not a search under the Fourth and Fourteenth Amendments. Beauford instead rested on state constitutional grounds, Article 1, § 8 of the Pennsylvania Constitution, which may be employed to guard individual privacy rights against unreasonable searches and seizures more zealously than the federal government does under the Constitution of the United States by serving as an independent source of supplemental rights. Beauford, 327 Pa.Superior Ct. at 262, 475 A.2d at 788.
Precedent for this analysis in Beauford was supplied by our earlier case of Commonwealth v. DeJohn, 486 Pa. 32, 403 A.2d 1283 (1979), in which we rejected federal law by [413]*413deciding that under our own Constitution police can gain access to banking records “only through a warrant based on probable cause.” Beauford extended “the DeJohn holding to information obtainable through the use of a pen register.” Beauford, 327 Pa.Superior Ct. at 264, 475 A.2d at 789. “Moreover,” the Court argued, “our constitutional interpretation derives independent support from Pennsylvania’s long history of affording special protection to the privacy interest inherent in a telephone call,” citing Commonwealth v. Papszycki, 442 Pa. 234, 275 A.2d 28 (1971), which construed legislative intent as requiring strict observance of privacy rights as to such intrusions into telephone conversations.4 Also see, Commonwealth v. Platou, 455 Pa. 258, 312 A.2d 29 (1973), cert. den., 417 U.S. 976, 94 S.Ct. 3183, 41 L.Ed.2d 1146 (1974). Cf. Commonwealth v. Stehley, 235 Pa.Superior Ct. 150, 338 A.2d 686 (1975) (expectation of privacy in regard to a pen register can be adequately protected by the Fourth Amendment and “we find no significant expectation of privacy to exist with respect to the destination of one’s phone calls”).
While we remain cognizant of the appearance that federal standards allow greater latitude in law enforcement, it is clear to us that Beauford represents the marked trend of our state law to bring intrusions into telephone communications within the confines of an expectation of privacy under the State Constitution and thereby be subject to the requirements demonstrating probable cause.5 In this analysis, of [414]*414course, we recognize that a judicial order authorizing the installation of pen registers is the equivalent of a search warrant in its operative effect where the intrusion involves a violation of a privacy interest protected under Article 1, § 8 of the Pennsylvania Constitution. As such, the affidavit and order must comply with the requirements of probable cause required under Pa.R.Crim.P. Chapter 2000, Search Warrants. On this point, see Beauford, 475 A.2d at 791, n. 7.
In Beauford, the Superior Court intended to equate telephone numbers with other forms of telephone communication which are regarded as private. Telephone activities are largely of one piece, and efforts to create distinctions between numbers and conversational content are constitutionally untenable in our view.
That Beauford was applied retroactively is equally correct. The Superior Court majority analyzed the issue solely on the basis of Commonwealth v. Cabeza, 503 Pa. 228, 469 A.2d 146 (1983), which requires that criminal cases be given retroactive applicability where the opinion does not render it prospective only and where the defendant has preserved the issue through every level of his proceedings. We pause momentarily to point out that Commonwealth v. Gillespie, 512 Pa. 349, 516 A.2d 1180 (1986), restricts retroactivity to cases on direct review where the issue was properly preserved, while there is language in Commonwealth v. Harper, 512 Pa. 155, 516 A.2d 319 (1986) (Mr. Justice Papadakos concurrence), which takes the analysis back to the familiar tripartite standard of Stovall v. Denno, 388 U.S. 293, 87 S.Ct. 1967, 18 L.Ed.2d 1199 (1967). We need not go any further at this point than to indicate that under either standard, retroactive application comports with our law on the facts of this case.
Our next issue for review is the good faith exception doctrine which the Superior Court read in this case. That decision represents the only instance in our state jurispru[415]*415dence so far to have attempted to read our State Constitution according to the Leon or Sheppard rationale. In Commonwealth v. Mason, 507 Pa. 396, 405, n. 2, 490 A.2d 421, 425, n. 2 (1985), Mr. Justice Larsen expressed no “opinion at this time” as to whether Leon could be applied to the state exclusionary rule. Unfortunately, the present Superior Court simply misreads Justice Byron White’s language in those cases, and the doctrine as applied here must be rejected on review.
In Leon, the court concluded in relevant part (468 U.S. at 923, 104 S.Ct. at 3421):
The exception we recognize today will also not apply in cases where the issuing magistrate wholly abandoned his judicial role, in a manner condemned in Lo-Ji Sales, Inc. v. New York, 442 U.S. 319, [99 S.Ct. 2319, 60 L.Ed.2d 920] (1979); in such circumstances, no reasonably well-trained officer should rely on the warrant. Nor would an officer manifest objective good faith in relying on a warrant based on an affidavit so lacking in indicia of probable cause as to render official belief in its existence entirely unreasonable. Brown v. Illinois, 422 U.S. [590] at 610-611 [95 S.Ct. 2254 at 2265-2266, 45 L.Ed.2d 416 (1975)].
This conclusion followed from Justice White’s insistence that “it is clear that in some circumstances the officer will have no reasonable grounds for believing that the warrant was properly based.” Id., 468 U.S. at 922-923, 104 S.Ct. at 3420-3421, footnote omitted.
We do not brush aside lightly the concerns of law enforcement officers in pursuing criminal activity when we reject the application of the good faith exception doctrine to this case. It is patently obvious to us, however, that the “reasonable” standard of Leon was violated and that the evidence cannot stand. As the Superior Court’s own opinion makes clear:
As with all searches not falling within one of the recognized exceptions to the warrant requirement, a finding that probable cause exists must be made by a neutral judicial authority before a pen register can be installed.
[416]*416The magistrate must make a judicial determination, albeit a nontechnical, common sense judgment ... as to whether probable cause exists. It is not enough for a policeman to present an affidavit to the magistrate prior to the search which affidavit the judiciary may consider on the issue of probable cause with complete hindsight after the police have completed their search. The magistrate must actually make a finding of probable cause to validate the warrant before he issues it. Moreover, he must do it by written order.
Commonwealth v. Chandler, 505 Pa. 113, 123-124, 477 A.2d 851, 856 (1984) (emphasis added).
In the instant case, the orders authorizing installation and use of pen registers were not based upon findings of probable cause. At the time when the applications for the use of pen registers were made, both the affiants and Judge Conroy were operating under the belief that a warrant based upon probable cause was not a necessary condition for the use of a pen register. It was for this reason that Judge Conroy made no findings before issuing orders authorizing installation of the pen registers in question. The orders do not suggest that Judge Conroy ever considered whether probable cause existed.
Moreover and in any event, the affidavits accompanying the pen register applications were insufficient to show the existence of probable cause. The affidavits in support of the Mastro and DeStefano pen registers contained vague and conclusory averments in support of the reliability of the tips received from the confidential informants; and police attempts to corroborate the information had been inconclusive. The affidavit in support of the installation of the DiJoseph pen register was based entirely upon information obtained through the Mastro pen register. Absent this information, the affidavit was void of facts showing probable cause.
Melilli, 522 A.2d at 1110-1111.
These conclusions by the Superior Court regarding the reliability of the informants were based on the decisions of Suppression Court Judge Samuel Lehrer:
[417]*417THE COURT: All right. Well, I have pretty much made up my mind on the sufficiency or lack thereof on this affidavit.
# * # * * *
THE COURT: Well, I believe that the application, I believe that C-l taken in its entirety, but was particularly with reference to the 4 corners of the affidavit of C-l, that the probable cause is lacking, and that Judge Conroy in signing this order lacked authority to do so.
* * * * * He
Also, generally, just briefly speaking, I believe that in addition to that fact the issuing authority here, the Municipal Court Judge Perforce had to consider the application as part of the affidavit, and that I can’t find that he acted in a neutral capacity which is required of an issuing authority, since it is obvious that he was also influenced by the application and its misrepresentations as to the state of the law or his own duty under the circumstances.
There are other reasons, but I see no reason to elaborate on them at this time. Now, with reference then to — therefore, the evidence obtained under this order will not be admissible against the Defendant Mastro and all those other persons who have been identified as a result of an application of the devices installed.
(Record, pp. 401a-403a; all of the applications and affidavits pertaining to this case appear herein at 468a-797a.) The DeStefano and DiJoseph pen register warrants (C-6 and C — 11 respectively) were also voided:
THE COURT: There are outstanding motions to suppress two Pen Registers and three wiretaps. I believe that the two Pen Registers still outstanding are C-6 and C-ll.
All right. The Court finds that these two Pen Registers lack probable cause. The motion to suppress those is granted. (Record, 455(a)-456(a).
Judge Lehrer’s exhaustive opinion (Supplemental Record, pp. 823a-896a) included Findings of Fact which, in brief, are relevant to our analysis. As to C-l, the “affiant’s informa[418]*418tion is in the nature of double hearsay;” the Trooper-affiant was not a party to any alleged conversation between the informant and the dialer; no information in the affidavit explains “the significance of these addresses or their relationship to each other;” evidence of prior arrests fail to “establish timeliness, freshness, or other relevancy;” the affiant “does not state how the surveillance was conducted, which days, over what span of time;” the affiant failed to “state any specific manner personally known to him of events or conduct supporting Richard Mastro’s alleged reputation as a Major Gambling figure.” (Id., infra, pp. 840a-842a). As to C-6, “the confidential informant passed his information on to a person who was not the affiant;” no “suspicious activity was observed;” there “is nothing in the affidavit” to show that “NICK” was Nicholas DeStefano; the affidavit is ambiguous as to which information led to arrests, nor are there facts stated to test the “freshness” of the information; there “is no reasonable basis (other than conjecture) in the affidavit for evaluating the confidential informant’s reliability.” (Id., infra, 854a-856a.) As to C-11, Judge Lehrer concluded curtly that “the information in the affidavit is derived from data obtained from pen register and DNR device installed” on Mastro’s line. (Id., p. 861a).
We see no reason to quarrel with Judge Lehrer’s opinion. It is sufficient to note that the orders for the pen registers failed the “totality of circumstances” test required by Illinois v. Gates, 462 U.S. 213, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983), which we adopted as the state test in Commonwealth v. Gray, 509 Pa. 476, 503 A.2d 921 (1985):
The task of the issuing magistrate is simply to make a practical, common-sense decision whether, given all the circumstances set forth in the affidavit before him, including the “veracity” and “basis of knowledge” of persons supplying hearsay information, there is a fair probability that contraband or evidence of a crime will be found in a particular place. And the duty of a reviewing court is simply to ensure that the magistrate had a “substantial [419]*419basis for ... concluding] that probable cause existed.” Jones v. United States, [362 U.S. 257, 271, 80 S.Ct. 725, 736, 4 L.Ed.2d 697 (1960)].
Gates, 462 U.S. at 238-239, 103 S.Ct. at 2332.
In Commonwealth v. Chandler, we addressed this matter further (505 Pa. at 121-123, 477 A.2d 851):
It is not enough, absent exigent circumstances, that a policeman believe the facts he has are a probable cause for a search warrant. The people of this state and nation are constitutionally entitled to an independent judicial determination of probable cause before they must open to the policeman’s knock at the door in the night. See Johnson v. United States, 333 U.S. 10, 68 S.Ct. 367, 92 L.Ed. 436 (1948). Moreover, that determination must be made before and not after the search. The written affidavit of probable cause simply insures an accurate record of the verified (sworn) facts the issuing authority had when he made his determination before the event. See Pa.R.Crim.P. 2003(a), quoted post [505 Pa.] at p. 123, n. 4 [477 A.2d at p. 856, n. 4]. Such a prior reduction to a written affidavit is of course particularly useful since stenographic records are not made in such matters before the District Justice. The written affidavit also eliminates the unseemly necessity of calling the judicial officer himself to the stand in a swearing contest with the policeman to determine what each knew when. The facts in the affidavit, however, are not the District Justice’s judgment. Indeed, they are only testimonial evidence of the facts themselves.
Reasonable judges and legal scholars may well differ over the technicalities of how best to memorialize the facts the issuer of the warrant had when he issued it and how technical courts should be in reviewing his decision to issue. We believe, however, none ever doubted the necessity of the exercise of judicial discretion.
‡ ift ‡ $ $
The issuing judicial authority, in this case a District Justice, has the authority and obligation to draw such [420]*420reasonable inferences as he will from the material supplied to him by police applying for a warrant and to make a finding on the issue of probable cause. Moreover, the magistrate is free to exact such assurances as he deems necessary to insure that the information on which probable cause is based has been obtained in a reliable way from a credible person. Illinois v. Gates, 462 U.S. 213 at 240, 103 S.Ct. 2317 at 2333, 76 L.Ed.2d 527 at 549 (1983).
The magistrate’s function is more than the ministerial one of administering an oath to an officer who has set forth facts the officer believes constitute probable cause. The magistrate must make a judicial determination, albeit a non-technical, common sense judgment, see Gates, as to whether probable cause exists.
Such judicial behavior surely was envisioned by Leon’s strictures as noted above, for here, the issuing authority “wholly abandoned his judicial role.” We leave for another day and another differing set of facts to determine whether a good faith exception will be read into the law of this jurisdiction.
Our final issue for review is the Superior Court’s holding that even in the absence of the good faith exception doctrine, the warrants for the subsequent wiretaps of Mastro and DeStefano were valid because of the reliability of the informants. The correct inquiry must go much further in determining whether the wiretaps were the poisoned fruit of the tainted pen registers or whether there was an independent basis for the wiretaps as claimed by the Commonwealth. Our acceptance of the exclusionary rule in Mapp v. Ohio, 367 U.S. 643, 81 S.Ct. 1684, 6 L.Ed.2d 1081 (1961), is aimed at depriving the police of the benefits derived from using information which was obtained unlawfully. See, Commonwealth v. Brown, 470 Pa. 274, 368 A.2d 626 (1976).
The classic analysis depends on whether the evidence was the product of the initial illegality or was secured by means sufficiently different to remove the primary taint. Wong Sun v. United States, 371 U.S. 471, 83 S.Ct. 407, 9 L.Ed.2d [421]*421441 (1963), as cited early in our cases of Commonwealth v. Holton, 432 Pa. 11, 247 A.2d 228 (1968); Commonwealth v. Moody, 429 Pa. 39, 239 A.2d 409 (1968); and Commonwealth v. Bishop, 425 Pa. 175, 228 A.2d 661, cert. den., 389 U.S. 875, 88 S.Ct. 168, 19 L.Ed.2d 159 (1967). If the prosecution can demonstrate that the allegedly tainted evidence was procured from an independent origin — a means other than the tainted sources — the evidence will be admissible. Silverthorne Lumber Co. v. United States, 251 U.S. 385, 40 S.Ct. 182, 64 L.Ed. 319 (1920), and Segura v. United States, 468 U.S. 796, 104 S.Ct. 3380, 82 L.Ed.2d 599 (1984); for Pennsylvania cases construing Silverthorne, see, for example, Commonwealth v. Brown, supra; Commonwealth v. Garvin, 448 Pa. 258, 293 A.2d 33 (1972); Commonwealth v. Cephas, 447 Pa. 500, 291 A.2d 106 (1972); and Commonwealth v. Bishop, 425 Pa. 175, 228 A.2d 661 (1967). In sum, admissibility will not lie where the road between the original tainted evidence and the poisoned fruit is direct and uninterrupted.
Based on the facts of this case, it is obvious that the wiretap warrants grew out of the information gained by virtue of the use of the pen registers. The police, in effect, would not have been led to the act of wiretapping those specific phones had they not had data from the pen registers in the first place. The wiretaps were linked directly to the pen registers and must be excluded also as fruit of the poisonous tree.6
Ever mindful of the severity of suppressing evidence, we must comply faithfully, nonetheless, with the safeguards provided to our citizens by the federal and state constitu[422]*422tions. We vacate the order of the Superior Court and reinstate the decision of the suppression court below.
NIX, C.J., and FLAHERTY, J., concur in the result.
