OPINION OF THE COURT
Hаrry Lee Riddick, Jr. appeals his conviction following a jury trial. Riddick raises multiple claims including that there was a variance between the single conspiracy charged and the evidence produced at trial, there was insufficient evidence to support his continuing criminal enterprise (“CCE”) conviction, the Government both improperly disclosed and presented misleading grand jury testimony, the court erred in denying Rid-dick’s suppression motion, and the Government conducted an unauthorized wiretap. The court affirms the conviction.
The Government cross-appeals Riddick’s sentence to a term of 33 years on the CCE count. The Government contends that the district court erred in assigning Riddick an offense level of 42 based on the United States Sentencing Commission, Guidelines Manual, § 2D1.5 (Nov.1995) (hereinafter “USSG”), the guideline applicable to his CCE conviction, even though USSG § 2D1.2, the guideline applicable to his conviction for distribution of cocaine near a school, required a higher offense level of 43 and a mandatory life sentence. The court vacates the sentence and remands for resentencing. 1
Factual Background
This case began with an indictment against twenty three defendants who engaged in a drug distribution conspiracy in Pennsylvania from 1989 to 1994. The Government filed a superseding indictment in July 1994 against the original defendant and co-defendants, including Riddick. The indictment charged Riddick with one count of engaging in a continuing criminal enterprise (21 U.S.C. § 848(a)), one count of conspiring to distribute more than five kilograms of cocaine (21 U.S.C. § 846), thirteen counts of distributing *508 cocaine in or near a school (21 U.S.C. § 860(a)), and one count of distribution of cocaine (21 U.S.C. § 841(a)(1)).
On February 6,1996, a jury convicted Rid-dick on all counts. 2 Following a sentencing hearing, the court found Riddick’s CCE involved in excess of 150 kilograms of cocaine. The court based this finding on the Government’s calculation that Riddick was responsible for in excess of 350 kilograms, the probation officer’s calculation which was in excess of 250 kilograms, and the court’s own detailed assessment of the trial evidence, including evidence of the length of time of the conspiracy, the suppliers, the sellers, and the amount of cocaine distributed each week.
The Government argued that Riddick should be sentenced under the Sentencing Guideline section resulting in the highest offense level within the group of counts. The Government reasoned that here, the conviction for distribution of cocaine near a school, rather than the conviction for operating a CCE, provided the higher offense level and life imprisonment. Moreover, the Government argued that the court was not precluded from sentencing Riddick on the distribution near a school counts because that offense is not a lesser included offense of the CCE count. The district court rejected this argument and held that “if you charge ... continuing criminal enterprise, ... that offense is so odious and so severe that if the Government secures a conviction on that offense, then the sentence should be imposed on that offense, even if it [is] not technically a lesser included offense.”
Thus, thе court imposed a sentence of 33 years on the CCE count. The district court did not dismiss the remaining counts and did not sentence Riddick on them. This appeal followed.
Jurisdiction
The district court exercised jurisdiction pursuant to 18 U.S.C. § 3231 (1994) because the case involved offenses against the laws of the United States. This court has jurisdiction of appeals from all final decisions of the district court pursuant to 28 U.S.C. § 1291 (1994). In addition, this court has jurisdiction over an apрeal by the Government for review of a final sentence pursuant to 18 U.S.C. § 3742(b) (1994).
Discussion
I.
A. Variance
Riddick claims that there was a prejudicial .variance between the indictment and the trial evidence because he and co-defendant Shannon Riley were charged as members of a single conspiracy, but the trial evidence showed that they were members of separate conspiracies. It is undisputed that the indictment charged that Riddick, and аll of his co-defendants including Shannon Riley, were part of a single conspiracy to distribute more than five kilograms of cocaine using Phill’s Bar and Grill, Allentown, as a headquarters and safe haven for drug dealing. Thus, the only remaining question is whether the jury properly found the existence of a single conspiracy. The existence of a single conspiracy is a finding of fact that must be sustained if, when viewed in the light most favorable to the government, thеre is substantial evidence to support that finding.
United States v. Smith,
The court finds that the Government presented substantial evidence supporting the jury’s finding of a single conspiracy. The trial evidence showed that Riddick and Riley closely cooperated and consulted each other to protect Riddick’s ongoing cocaine operation. They supplied each other with information about law enforcement investigations. Riley used the “safe haven” that Riddick created at Phill’s Bar and Grill to sell cocaine, which she was permitted to do only because she was associated with Riddick. Thus, there was no variance between the indictment and the evidence, both of which show a highly interdependent group of sellers who shared a unity of purpose and who were led by Riddick.
*509 B. CCE Conviction
Riddick claims that there was insufficient evidence to support his conviction for operating a continuing criminal enterprise because the Government’s evidence showed that Riddick supervised only two “runners,” not five or more persons as required by 21 U.S.C. § 848(c).
3
The court reviews the sufficiency of the evidence in the light most favorable to the government and must credit all available inferences in favor of the government.
United States v. Dickens,
The court finds that the Government presented sufficient evidence to support Rid-dick’s conviction for оperating a CCE. The trial testimony shows that Riddick controlled more than five couriers and sellers. Riddick hired sellers, set daily guaranteed wages for sellers, set cocaine prices, provided pagers, and numerical identifier codes to his sellers, posted bail for arrested sellers, and obtained confidential police information to protect sellers. Riddick stationed certain sellers at Phill’s Bar & Grill, where they had the right to sеll cocaine. Other sellers sold door to door: Therefore, the testimony showed that Riddick had supervised numerous sellers in a unified drug ring.
C. Grand Jury Testimony
Riddick appeals the district court’s denial of his motion for a new trial by raising two arguments regarding grand jury testimony. Riddick claims that the contents of a newspaper article published six weeks before Riddick was indicted showed that confidential grand jury testimony by government witness Nigel McFarlane was leaked to the press in violation of Fed.R.Crim.P. 6(e). The district court’s denial is reviewed for abuse of discretion.
United States v. Gilsenan,
Second, Riddick claims that the Government presented misleading testimony to the grand jury or withheld exculpatory testimony from the grand jury. All of the “examples” cited by Riddick were refuted by the actual transcripts of the grand jury proceedings. Thus, this argument is also without merit.
D.Motion to Suppress Evidence
Riddick also claims that the district court erred in denying his motion to suppress evidence from the 1994 search of his home at 1106 1/2 Tilghman Street, on the grounds that: (1) the warrant contained stale facts, (2) the warrant failed to list with particularity the items to be seized, and (3) the agents seized items from 1108 Tilghman Street, a location not listed in the warrant. Riddick did not raise the first two claims in his suppression motion and therefore the district court’s denial is rеviewed for plain error. See Fed.R.Crim.P. 52(b).
Riddick’s first two claims are without merit. The warrant lists the items to be seized with sufficient specificity. Moreover, the information in the warrant was not stale; it showed an entrenched ongoing five-year drug operation in which Riddick frequently used his home to conduct cocaine transactions, and in which the most recent drug sale by one of his employees occurred only six days before the warrant was executed.
As fоr Riddick’s third claim, the court reviews the district court’s denial of the motion to suppress for “clear error as to the underlying facts, but exereise[s] plenary review as to its legality in light of the court’s properly found facts.”
United States v. Inigo,
E. Illegal Monitoring of Conversations
Riddick claims that the district court erred in denying his motion to suppress all electronic surveillance on two grounds. We review the district court’s factual findings for clеar error and exercise plenary review of the legal issues involved.
Inigo,
As none of Riddick’s contentions have merit, we affirm the conviction.
II.
A. Sentencing for Distribution of Cocaine Near a School
The Government argues that the district court erred by refusing to sentence Riddick pursuant to USSG § 2D1.2, the Sentencing Guideline applicable for drug offenses occurring near a school.
7
Section 2D1.2 should have been applied, the Government argues, because the Sentencing Guidelines requirе the use of the highest offense level within a group of counts. The standard of review of the district court’s interpretation and application of the Sentencing Guidelines is plenary.
United States v. Hallman,
Section 3D1.2(d) of the Sentencing Guidelines states that multiple counts “involving substantially the same harm shall be grouped together into a single Group. Counts involve substantially the same harm ... when the offense level is determined largely on the basis of ... the quantity of a substance involved.” USSG § 3D1.2(d). Offenses covered by the USSG § 2D1.2 (distribution near *511 a school) and USSG § 2D1.5 (continuing criminal enterprise offenses) are to be grouped together. USSG § 3D1.2(d). Moreover, in cases of grouping under § 3D1.2(d), “the offense guideline that results in the highest offense level is used.” USSG § 3D1.2 comment, (n.6).
Applied here, the counts for distribution of cocaine near a school (21 U.S.C. § 860(a)) and for operating a CCE (21 U.S.C. § 848) are properly groupеd together. See USSG § 3D 1.2(d). The counts for distribution of cocaine near a school result in a higher offense level than the CCE count. While Rid-dick’s offense level for CCE count is 42 pursuant to § 2D1.5, 8 Riddick’s offense level for distribution of cocaine near a school is 43. Specifically, the provision applicable for violations of § 860(a), USSG § 2D1.2, directs the court to add one offense level to “the offense level from § 2D1.1 applicable to the tоtal quantity of controlled substances involved in the offense.” USSG § 2D1.2(a)(2). Riddick’s offense level from § 2D 1.1 is 38 because the total quantity involved in the offense was more than 150 kilograms of cocaine. Thus, the base offense level would be 39, plus a 4-level increase under USSG § 3Bl.l(a) for Riddick’s role as leader or organizer of criminal activity involving five or more people. 9 The total offense level is 43, mandating a sentence of life imprisonment. Thus, under USSG § 3D1.2(d), the district court should have applied § 2D1.2 and sentenced Riddick to life imprisonment.
The district court, however, sentenced Riddick on the CCE count based on its perception that operating a continuing criminal enterprise constituted a more serious offense than the offense of distributing cocaine near a school or playground and thus the distribution count merged with the CCE count for sentencing purposes. The district court’s perception of the seriousness of the crime does not provide a basis on which the court may disregard the explicit instructions of the Sentencing Guidelines. The Guidelines do not direct the court to make a subjective determination of which count is the most severe or onerous in determining the sentence. See USSG § 3D1.2(d). Rather, the Guidelines suggest that the severity of the offense is fully accounted for in the court’s calculation of the offense level. Thus, the district court erred.
Moreover, even assuming
arguendo
that it is improper to impose a higher penalty for a “lesser included offense” than for' the more serious offense, substantive predicate offenses involved in a CCE conviction, such as Riddick’s violation of 21 U.S.C. § 860(a) for distributing cocaine in the vicinity of a school, are not lesser included offenses of the CCE count. The issue of whether one count is the lesser included offense of another arises when the court is confronted with two distinct statutory provisions applicable to the same criminal act. In such a situation, the court will look at “whether each provision requires proof of an additional fact which the other does not.”
Blockburger v. United States,
Further, the language of
Garrett
is not contradicted by
Rutledge v. United States,
*512
As various Courts of Appeals decisions recognize, the Supreme Court has made clear that while a defendant may not be sentenced, even concurrently, to both a conspiracy conviction and a CCE conviction because оne is the lesser included offense of the other, the same rule does not apply when the predicate offense is a separate substantive offense. Substantive predicate offenses do not merge with the CCE count.
See United States v. Grayson,
Thus, the district court was not precluded from sentencing Riddick on the counts for distribution of cocaine near a school.- Accordingly, we conclude that the district court erred by failing to sentence Riddick to life imprisonment pursuant to USSG § 2D1.2 for his conviction under 21 U.S.C. § 860(a) and for his role as an organizer pursuant to USSG § 3Bl.l(a).
Riddick’s challenge to the district court’s factual findings does not affect the court’s conclusion. Riddick argues that even if the court concludes that he is to be sentenced under USSG § 2D1.2, he should not receive a life sentence. Riddick bases this claim on his belief that the court made the erroneous factual finding that 150 kilograms of cocaine were attributable to him. With an accurate assessment of the quantity of cocaine a lower base offense level would apply and would preclude a sentence of life in prison.
As proof of the inaccuracies, Riddick states that the' court added quantities for which there was no record evidence presented or dates setting forth when the transactions occurred. Even allowing for the 75 kilograms assessed to him in 1993, Riddick argues that the Government can prove that he distributed no more than 108.75 kilograms of cocaine and even this amount was based on improperly drawn inferences from testimony of a man who was in prison for at least part of the time he was allegedly making sales to Riddick. Finally, Riddick contends that any conclusion that he was responsible for the total quantity of drugs involved in the CCE was in error because the district court did not make a finding that it was reasonable to impute knowledge of all the conspiracy’s criminal conduct to him. As indicated previously, however, the district court made clear factual findings based on equally clear reasoning. Riddick has presented nothing to suggest that the court’s detailed factual finding that he was responsible for 150 kilograms of cocaine, an estimate significantly lower than either that of the Government or of the probation officer, is clearly erroneous.
*513 III.
In sum, we affirm the conviction, vacate the sentence, and remand for resentencing in accordance with this opinion.
Notes
. Because a mandatory life sentence is required on the school count, thе court does not reach the issue of whether the district court erred in refusing to sentence Riddick to the statutorily mandated term of life in prison for his CCE conviction as required by 21 U.S.C. § 848(b).
. Any facts relevant to Riddick's appeal of his conviction are discussed in Section I.
. Riddick also claims that the district court improperly admitted evidence of Nigel McFarlane’s dealings with Dominican and Colombian drug dealers as "other acts” evidence relating to Rid-dick’s own conduct. Riddick fails to cite any part of the trial record or to specify what part of McFarlane’s testimony was allegedly objectionable. Thus, this claim is without merit.
. Riddick had modified the third floor of 1106 1/2 Tilgham Street, expanding it into space for *510 merly belonging to 1108 Tilgham Street. Rid-dick’s alterations, however, permanently made the extra space part of 1106 1/2 Tilgham by eliminating access to the bedroom from 1108 Tilgham. Thеrefore, the agents properly searched the space under the authority of the warrant.
. A pen register is a "device which records or decodes electronic or other impulses which identify the numbers dialed or otherwise transmitted on the telephone line to which such device is attached.” 18 U.S.C. § 3127 (1994);
see also In re Grand Jury Proceedings,
. There were recordings made prior to December 1993, but they were made with the consent of one of the parties to the conversation and Rid-dick has not addressed these specifically.
.Riddick argues that the Government has waived its right to appeal the court's failure to apply USSG § 2D 1.2. Riddick relies on the Government's statement at the sentencing hearing, that regardless of whether the court sentenced Riddick under the CCE statute or the conspiracy statute the end result would be a life sentence, as evidence that the Government did not raisе this guideline provision as an alternative sentencing option before the district court.
This argument is without merit. At the conclusion of the sentencing hearing the district court stated "[t]he Government urges that the counts involving distribution near a school are not lesser included offenses to the continuing criminal enterprise count, and therefore, I would have the option ... to sentence to the higher amount,” suggesting quite clearly that the Governmеnt raised the issue below.
. Sentencing Guideline § 2D1.5 applies to the CCE count. Here, the base offense level is 4 plus the offense level from § 2D 1.1, for a total of 42, mandating a sentence of 360 months to life.
. Riddick did not contest the four level increase pursuant to USSG § 3131.1(a) on appeal. Rid-dick, however, appealed the sufficiency of the CCE conviction involving the same facts. In part IB, supra, we concluded that there was sufficient evidence on this point to sustain the jury’s verdict.
