United States v. Marrero-Ortiz

Check Treatment

SELYA, Circuit Judge.

In the wake of his conviction on a charge of conspiracy to possess controlled substances with intent to distribute, see 21 U.S.C. §§ 841(a)(1), 846 (1994), defendant-appellant Luis Marrero-Ortiz (Marrero), one of thirty-one defendants named in a wide-ranging indictment, claims that the district court committed a host of errors. We have reviewed the trial record with care and find Marrero’s multi-pronged attack on his conviction meritless. Withal, one aspect of the trial court’s sentencing determination gives us pause.

With this brief prelude, we proceed to discuss Marrero’s principal assignments of error, segregating those points that relate to his conviction from those that relate to sentencing. 1

Trial Issues

We start by addressing those assignments of error that center on the trial.

1. Sufficiency of the Evidence. On a defendant’s timely motion, a federal trial court is constrained to order a judgment of acquittal with respect to any given charge if the government fails to present sufficient evidence to sustain a conviction. See Fed. R.Crim.P. 29(a). In this instance, the appellant sought—but did not secure—-judgment of acquittal under Rule 29. We review the district court’s determination de novo, applying precisely the same standard that obtained below: “whether, after assaying all the evidence in the light most amiable to the government, and taking all reasonable inferences in its favor, a rational factfinder could find, beyond a reasonable doubt, that the prosecution successfully proved the essential elements of the crime.” United States v. Hernandez, 146 F.3d 30, 32 (1st Cir.1998) (citation and internal quotation marks omitted).

“To prove a drug conspiracy charge under 21 U.S.C. § 846, the government is obliged to show beyond a reasonable doubt that a conspiracy existed and that a particular defendant agreed to participate in it, intending to commit the underlying substantive offense.... ” United States v. Sepulveda, 15 F.3d 1161, 1173 (1st Cir.1993). The prosecution may meet its burden through either direct or circumstantial evidence, or through some combination thereof. See United States v. Houlihan, 92 F.3d 1271, 1292 (1st Cir.1996).

*773 In this case, the appellant claims that the government’s proof fell short in two respects because the evidence failed to show either that he agreed to participate in the conspiracy or that he possessed an intent to commit the underlying offense. This claim rests mainly on the assertion that the prosecution offered no direct proof that the appellant personally engaged in drug transactions. The claim is groundless: proof of direct participation in the sale of drugs is not required to convict in a drug conspiracy casé. See, e.g., United States v. David, 940 F.2d 722, 735 (1st Cir.1991).

In all events, a percipient witness, Marcos Hidalgo Melendez (Hidalgo), himself a coconspirator, testified that he received money from the appellant after delivering narcotics to him. Furthermore, Hidalgo and another admitted coconspirator testified in substance that Marrero served as a supervisor at the drug ring’s distribution center in Corozal. This evidence, in conjunction with testimony concerning (i) the appellant’s frequent presence at the ring’s distribution center in Arecibo, (ii) the appellant’s wounding during a skirmish between rival drug gangs (see infra Point 3), (iii) the inclusion of the appellant’s name and telephone number in a drug ledger and related records seized from the ringleader’s home, and (iv) the appellant’s repeated posting of bail for members of the conspiracy, was sufficient to ground the jury’s verdict. See United States v. Ortiz, 966 F.2d 707, 712 (1st Cir.1992) (permitting factfinders to “draw reasonable inferences from the evidence based on shared perceptions and understandings of the habits, practices, and inclinations of human beings,” and warning that, in assessing sufficiency challenges, factfinders are required neither “to divorce themselves from their common sense nor to abandon the dictates of mature experience”).

2. Variance. A variance occurs when the facts adduced at trial differ meaningfully from those adumbrated in the indictment. The appellant contends that the instant indictment contained a fatal variance because it charged him with supervising a drug point in Arecibo, while the evidence introduced at trial linked him primarily to drag transactions in Corozal. We reject this contention.

In a criminal case, not every difference between the indictment and the proof justifies relief; only those instances in which a disparity is material and affects a defendant’s substantial rights warrant reversal. See United States v. Tormos-Vega, 959 F.2d 1103, 1115 (1st Cir.1992) (explaining that a variance justifies reversal only if it materially impairs the defendant’s right to “have sufficient knowledge of the charge against him in order to prepare an effective defense and avoid surprise at trial”); accord United States v. Fisher, 3 F.3d 456, 463 (1st Cir.1993). We think that the charging document suffices in this case.

The indictment describes the manner and means of the conspiracy as the retail distribution of narcotics at numerous locations (“puntos”) controlled by the so-called Santiago organization, specifically, Arecibo and “elsewhere.” It then limns 42 overt acts, including some acts committed at Arecibo and some at Corozal. In paragraph 22 the indictment charges the appellant, acting in furtherance of the conspiracy, with possession of a firearm in Corozal. These allegations provided an adequate preview of the proof to come.

The government need not recite all its evidence in the indictment, nor is its trial proof limited to the overt acts specified therein. See United States v. Bradstreet, 135 F.3d 46, 53 (1st Cir.1998); United States v. Innamorati 996 F.2d 456, 477 (1st Cir.1993); United States v. Bello-Perez, 977 F.2d 664, 669 (1st Cir.1992). In this instance, the indictment, despite its emphasis in paragraph 10 on the appellant’s control over the sale of drugs in Arecibo, put him squarely on notice that the prosecution viewed his dealings in Corozal as an integral part of the conspiratorial mix. Because the appellant cannot credibly claim surprise, the asserted variance does not warrant setting aside the verdict.

3. The Shooting Incident. The appellant protests a district court ruling permitting the prosecution to introduce evidence about his involvement in a shooting incident *774 in Corozal. The nature of the evidence is described in the margin. 2 We conclude that the court acted within its discretion in admitting the evidence.

Relevant evidence is evidence that has a “tendency to make the existence of any fact ... more probable or less probable than it would be without the evidence.” Fed. R.Evid. 401. Evidence, though relevant, nonetheless may be excluded if its probative value is overbalanced by other considerations, such as by the danger of unfair prejudice. See United States v. McKeeve, 131 F.3d 1, 13 (1st Cir.1997) (citing Fed.R.Evid. 403). Virtually all evidence is meant to be prejudicial, and it is only unfair prejudice against which Rule 403 protects. See United States v. Pitrone, 115 F.3d 1, 8 (1st Cir.1997); Houlihan, 92 F.3d at 1297. Because such determinations are peculiarly within the ken of trial courts, we review them only for abuse of discretion. See Pitrone, 115 F.3d at 7; Houlihan, 92 F.3d at 1297.

Concluding that evidence of the shooting incident made it more probable that Marrero was a member of the conspiracy, and that the evidence’s probative worth outweighed any unfairly prejudicial effect, the district court admitted the evidence. We decline to second-guess this ruling. See Freeman v. Package Mach. Co., 865 F.2d 1331, 1340 (1st Cir.1988) (“Only rarely—and in extraordinarily compelling circumstances—will we, from the vista of a cold appellate record, reverse a district court’s on-the-spot judgment concerning the relative weighing of probative value and unfair effect.”).

4. Rule 12(d)(2). Citing Fed. R.Crim.P. 12(d)(2), the appellant assigns error to the district court’s admission of certain evidence during trial. 3 The background is as follows. Because of the numerosity of defendants, the district court ordered two separate trials on the indictment. The court placed the appellant in the second group. The government designated all its evidence prior to the first trial, but did not renew the designation prior to the second trial.

Without citing any pertinent authority, the appellant claims that the government had an obligation to redesignate the evidence before using it at the second trial. The applicable test is for abuse of discretion, see United States v. de la Cruz-Paulino, 61 F.3d 986, 993 n. 3 (1st Cir.1995), and we are not persuaded that the district court perpetrated an abuse when it ruled that the initial designation satisfied Rule 12(d)(2)’s notice requirements. Under the circumstances, redesig-nation would have served no useful purpose.

We add that, even if the government’s failure to redesignate the evidence technically violated the rule, the violation did not prejudice the defense. The appellant’s main emphasis in this aspect of his appeal relates to certain incriminating statements allegedly made by him after the shooting incident described in Point 3, supra. Rule 12(d)’s function is procedural; compliance with its terms enables a defendant to move for suppression in a timely manner. Here, the district court permitted the appellant, out of time, to file a suppression motion addressed to the incriminating statements. See de la Cruz-Paulino, 61 F.3d at 994 n. 5 (endorsing this practice). The court then denied the motion, holding that the government had a right to use the statements. Given that eminently correct ruling, the appellant’s claim of prejudice rings hollow.

Taking an alternate tack, the appellant also suggests that the government’s failure to designate evidence relating to both his possession of firearms and his relationship with other participants in a drug transaction *775 violated Rule 12(d)(2). But the appellant is firing blanks; he makes no developed argument for the suppression of such evidence. Absent some articulation of a convincing rationale for quashal, the lack of an opportunity to file a pretrial suppression motion cannot be viewed as prejudicial. See id. at 994.

5. Cross-Examination. The appellant complains that the district court transgressed his fundamental right to cross-examine adverse witnesses when it barred him from eliciting testimony, through cross-examination of a prosecution witness, that local charges related to his arrest for weapons possession had been dismissed. Managing the scope of cross-examination is a matter that falls within the district court’s sound discretion. See United States v. Boylan, 898 F.2d 230, 254 (1st Cir.1990). We are confident that the court did not abuse its discretion when it prohibited the appellant from cross-examining the witness regarding the prior proceeding.

This court recently joined several other circuits in holding that a district court has discretion to exclude from evidence acquittals or other favorable outcomes of prior state court proceedings involving the same subject matter. See United States v. Smith, 145 F.3d 458, 462 (1st Cir.1998); accord United States v. Thomas, 114 F.3d 228, 249-50 (D.C.Cir.), cert. denied, — U.S. -, 118 S.Ct. 635, 139 L.Ed.2d 614 (1997); United States v. Jones, 808 F.2d 561, 566 (7th Cir.1986); United States v. Irvin, 787 F.2d 1506, 1516-17 (11th Cir.1986); United States v. Sutton, 732 F.2d 1483, 1493 (10th Cir.1984); United States v. Viserto, 596 F.2d 531, 537 (2d Cir.1979). The rationale is plain: such evidence ordinarily does not prove innocence. After all, cases are dismissed for a variety of reasons, many of which are unrelated to culpability. Because evidence of a dismissal may have served to confuse the jury rather than to assist it, 4 the district court had the authority to exclude such evidence here. See Fed.R.Evid. 403.

Undaunted, the appellant makes a related argument. He says that, even if the district court ordinarily can exclude such evidence, it should not have done so here because it permitted a government witness to testify that Marrero had been arrested locally. The law is against the appellant’s position: other courts have held routinely that a district judge does not abuse his discretion by allowing some evidence related to a local proceeding, yet barring evidence of the outcome of that proceeding. See, e.g., Jones, 808 F.2d at 566-67; Sutton, 732 F.2d at 1493. We need not go so far, however, for in this instance, the appellant opened the door by inquiring during cross-examination if the witness personally arrested Marrero. He cannot now be heard to complain that the government followed his lead and elicited the challenged testimony on redirect. 5

6. Jeneks Act. The Jeneks Act, 18 U.S.C. § 3500, in concert with Fed. R.Crim. P 26.2, controls the production of certain witness statements in the government’s possession. In this case, the appellant sought to inspect rough notes taken by an Internal Revenue Service agent, Felicia Ramos, during an interview of Hidalgo (who testified at the trial as a government witness). The appellant maintains that the notes comprised a “statement” under 18 U.S.C. § 3500(e)(1), that the government therefore was obliged to produce them, and that their availability would have enabled him to impeach Hidalgo’s credibility. We do not agree.

The Jeneks Act ordains that “[a]fter a witness called by the United States has testified on direct examination, the court ■shall, on motion of the defendant, order the United States to produce any statement ... of the witness in the possession of the United States which relates to the subject matter as *776 to which the witness has testified.” 18 U.S.C. § 3500(b). The question here is whether the notes constitute a “statement.” The statute itself provides some enlightenment, defining a “statement” as one “made by said witness and signed or otherwise adopted or approved by h[er]” 18 U.S.C. § 3500(e)(1). A written summary of a witness interview is not a statement unless the evidence shows that the witness adopted the notes, a phenomenon that would occur, for example, if “the interviewer read the statement back to the witness and ... the witness approved the statement.” United States v. Gonzalez-Sanchez, 825 F.2d 572, 586 (1st Cir.1987).

In this instance, the record is barren of any evidence that Hidalgo adopted the notes in question or that they otherwise satisfied the Jeneks Act’s definition of a statement. Hence, the government had no obligation to produce them and the denial of discovery was proper.

7. Anonymous Jury. Under 28 U.S.C. § 1863(b)(7), a district court may empanel an anonymous jury in any case in which “the interests of justice so require.” We recently held that this standard is satisfied when “there are strong grounds for concluding that [anonymity] is necessary to enable the jury to perform its factfinding function, or to ensure juror protection.” United States v. DeLuca, 137 F.3d 24, 31 (1st Cir.), cert. denied, — U.S. -, 119 S.Ct. 174, — L.Ed.2d-(1998) (No. 98-141). The trial court must take care, however, to implement reasonable safeguards “to minimize any risk of infringement upon the fundamental rights of the accused.” Id. Under these criteria, Judge Fusté did not exceed the scope of his discretion when he empaneled an anonymous jury in this case.

The indictment charged the appellant and his coeonspirators with membership in a sprawling drug ring that often resorted to violence in its pursuit of profits. The government’s evidence indicated, for example, that a co-defendant, Miranda, ordered the murders of six people during 1993 and 1994 in retaliation for the slaying of Santiago’s bodyguard. The appellant himself suffered a bullet wound while in the organization’s service. See supra Point 3. During the arraignment that followed the return of this indictment, a brawl erupted. Last—but surely not least—the government proffered evidence indicating that the Santiago drug ring was plotting to murder federal agents and local police officers to improve the odds at trial. Under these ominous circumstances, the court reasonably could have believed that the jurors were in harm’s way. In turn, this reasonable belief adequately supported the empanelment of an anonymous jury.

By like token, Judge Fusté took satisfactory precautions to protect the defendants’ rights. He did not mention any threat to juror safety, but, rather, informed the jurors that they would remain anonymous during the trial because of publicity concerns. He then instructed the jury on the presumption of innocence, and periodically repeated that instruction as the trial progressed. No more was exigible. See id. at 32.

8. Peremptory Challenges. In a related vein, the appellant argues that the empanelment of an anonymous jury created a need for additional peremptory challenges, beyond those ordinarily allowed. See Fed. R.Crim.P. 24(b) (delineating allotment and distribution of peremptories). Although the applicable rule allows a judge to grant additional challenges, the judge has wide discretion in administering this authority. See United States v. Cox, 752 F.2d 741, 747-48 (1st Cir.1985). The empaneling of an anonymous jury neither curtails the scope of this discretion nor obligates a district court to afford more peremptories to the defense. We therefore reject the appellant’s assignment of error. 6

*777 Sentencing Issues

We turn next to the appellant’s myriad challenges to the 360-month sentence that the district court imposed.

9. Continuance of Disposition Hearing. Fed.R.Crim.P. 32(a) requires, inter alia, that the trial court impose sentence without undue delay. Such a disposition occurs following the preparation of the presentence investigation report (PSI Report) and the lodging of objections théreto. See Fed.R.Crim.P. 32(b)(6)(C) (“Not later than 7 days before the sentencing hearing, the probation officer must submit the presentence report to the court, together with an addendum setting forth any unresolved objections ... [a]t the same time, the probation officer must furnish the revisions of the presentenee report and the addendum to the defendant.”). In this instance, the probation officer did not distribute the addendum to the PSI Report in a timely manner. The appellant—who unsuccessfully sought a continuance—makes three arguments in regard to this lapse: (1) that the probation officer’s failure to comply strictly with Rule 32 denied him the opportunity adequately to prepare a rebuttal to the PSI Report; (2) that the probation officer’s belated response to the appellant’s objections created unfair surprise; and (3) that, as a result of this surprise, defense, counsel was unable either to explain the PSI Report to his client or to discuss the proceedings with him.

Appellate review of a trial court’s ruling on a sentencing continuance is deferential. See United States v. Ottens, 74 F.3d 357, 359-60 (1st Cir.1996) (adopting abuse of discretion standard). The focus is on what constitutes a reasonable period of time for preparation, not on defense counsel’s “subjective satisfaction with his level of preparedness.” Id. at 359. In sifting the entire panoply of relevant considerations, the district court may consider factors such as prior continuances, time available for preparation, and how efficiently defense counsel used the available time. See id.

In the case at bar, the lower court postponed the disposition hearing for two months to give defense counsel more time to review the PSI Report. During this two-month interlude, defense counsel filed several objections (which prompted the addendum). Defense counsel at no time sought to introduce any new evidence, despite ample time to prepare rebuttal arguments. Finally, although defense counsel did not receive a copy of the addendum until the day before the new sentencing date, that document did no more than respond to points that' defense counsel himself had raised. He obviously had enough time to review it because he argued eloquently concerning the conclusions that it contained. Hence, the appellant’s first argument founders.

1 Nor can the appellant convincingly claim undue surprise. Defense counsel already had been granted a generous continuance. He knew the information contained within the PSI Report, and he had two months in which to prepare his rebuttal. The addendum did not contain any new information; it merely referenced trial testimony to refate the appellant’s objections and, concomitantly, to support the probation officer’s recommendation of a base offense level (BOL) of 38, a two-level upward adjustment for possession of a firearm, and a two-level enhancement for a supervisory role. The fact that the appellant received the addendum the day before sentencing, although vio-lative of Rule 32(b)(6)(C), is not sufficient, in and of itself, to establish undue surprise. See United States v. Williams, 499 F.2d 52, 54-55 (1st Cir.1974) (holding an analogous violation harmless on the ground that the PSI Report did not contain any information that the defendant could not have anticipated, despite the fact that the defendant received it five minutes before the disposition hearing).

Finally, the appellant’s claim that he did not have the opportunity to discuss the sentencing materials with his defense counsel is unsupported. The sentencing transcript reflects that the judge asked the appellant whether he had reviewed the PSI Report *778 with his attorney and the appellant replied “yes.” When asked if he had any further objections to it, the appellant replied “no.” Courts long have held that a defendant cannot make solemn representations at sentencing and freely disclaim them at a later date, when it is to his advantage to do so. See United States v. Mata-Grullon, 887 F.2d 23, 24 (1st Cir.1989).

10. Written Findings. Fed. R.Crim.P. 32(c)(1) requires that the trial court make a finding in respect to each matter controverted at sentencing (or, alternatively, make a finding that the controverted matter has no bearing). The rule also directs the sentencing court to append a written record of its findings to the judgment. See id. The appellant complains that the sentencing court neglected to follow this regimen.

When the sentencing court makes specific findings ore tenus, the court may append the sentencing transcript to the PSI Report and thus effect compliance with Rule 32(e)(1). See United States v. Bruckman, 874 F.2d 57, 65 (1st Cir.1989). Preparing an additional written record of findings is merely “ministerial,” and will not be required. Id.; accord United States v. Mena-Robles, 4 F.3d 1026, 1037 n. 14 (1st Cir.1993). The same is true when the court makes implicit findings by reference to detailed suggestions in the PSI Report. See United States v. Ovalle-Marquez, 36 F.3d 212, 227 (1st Cir.1994).

Against this backdrop, the record rebuts the appellant’s contention that the district court did too little. It shows that, at the disposition hearing, the judge made a specific finding as to each controverted matter: drag quantity, possession of a firearm, and role in the offense. If the transcript that embodies those findings has not already been appended to the PSI Report, we direct that this amalgamation be made. No more is necessary.

11. Possession of a Firearm. In this case, the district court increased the BOL by two levels because the appellant possessed a firearm in connection with his drag-trafficking activities. See USSG § 2D1.1(b)(1). The appellant urges us to nullify this enhancement. He bases his argument on an analogy to Bailey v. United States, 516 U.S. 137, 116 S.Ct. 501, 133 L.Ed.2d 472 (1995). For purposes of a prosecution under 18 U.S.C. § 924(c)(1), Bailey requires proof that the defendant’s “use” of a firearm had an active relation to the underlying drag offense (e.g., that the defendant displayed, fired, or brandished the weapon). See id. 116 S.Ct. at 503. We agree with the sentencing judge that Bailey is not controlling here.

The sentencing guidelines govern this sentence enhancement. The applicable guideline provides that “[i]f a dangerous weapon (including a firearm) was possessed,” the court should increase the defendant’s BOL by two levels. USSG § 2Dl.l(b)(l). The appellant argues that this guideline provision should be construed in pari materia with section 924(c)(1)—but he does not explain why this parallelism must exist. The language of the two provisions is dissimilar. 7 So, too, is their effect: a conviction under 18 U.S.C. § 924(c)(1) results in an incremental five-year consecutive sentence, while a sentence enhancement under USSG § 2D1.1(b)(1) results merely in a two-level adjustment to the defendant’s BOL. Most importantly, the interpretation of the guideline provision is colored by the Sentencing Commission’s instruction that “[t]he adjustment should be applied if the weapon was present, unless it is clearly improbable that the weapon was connected with the offense.” USSG § 2Dl.l(b)(2), comment, (n.3). This is a far cry from the way in which the Bailey Court instructs judges to approach section 924(c)(1).

We need not tarry. Bailey is inapposite here. And, moreover, the evidence amply supports a finding, by a preponderance, that the appellant possessed a firearm for poten- *779 tíal use in connection with his drug-trafficking activities. See, e.g., United States v. Berrios, 132 F.3d 834, 839 (1st Cir.1998); United States v. Gonzalez-Vazquez, 34 F.3d 19, 24 (1st Cir.1994); United States v. Ruiz, 905 F.2d 499, 507 (1st Cir.1990). Accordingly, the district court did not err in enhancing the appellant’s sentence under USSG § 201.1(b)(1).

12. Supervisory Role. The district court also boosted the appellant’s BOL for his role as a supervisor in the narcotics enterprise. The appellant claims that the finding lacks support. We disagree.

In order to qualify for a two-level enhancement as a supervisor in a criminal enterprise, a defendant must exercise control over at least one other culpable individual. See United States v. Akitoye, 923 F.2d 221, 227 (1st Cir.1991) (discussing USSG § 3B 1.1(c)). The appellant’s argument here boils down to a plaint that the district court made no specific findings in support of its determination that he deserved the enhancement. Although such findings are always helpful, they are unnecessary when the record clearly reflects the basis of the court’s determination. See United States v. Quinones, 26 F.3d 213, 219 (1st Cir.1994) (indicating a willingness to overlook the absence of findings “if the reasons for the judge’s choice are obvious or if an explanation can fairly be implied from the record as a whole”). This is such a case.

At trial, the government presented two witnesses who indicated that the appellant was in charge of the conspiracy’s drug point in Corozal. The government also presented testimony as to how the drug points were managed and the number of individuals involved. This evidence is self-explanatory and provides adequate support for the district court’s determination that the appellant ran a drug point and supervised others in so doing. See United States v. Cruz, 120 F.3d 1, 4 (1st Cir.1997) (en banc). 8

13. Drug Quantity. In a narcotics case, drug quantity is an important integer in calculating the BOL (and, hence, the sentence itself). See Sepulveda, 15 F.3d at 1197. To determine the drug quantity attributable to a particular defendant, a court looks to the quantity of drugs associated with the count(s) of conviction, plus all “relevant conduct,” i.e., those acts that were part of the same “‘common scheme or plan as the offense of conviction’, whether or not charged in the indictment.” United States v. Sklar, 920 F.2d 107, 110 (1st Cir.1990) (quoting USSG § lB1.3(a)(2)). In the case of a conspiracy, however, a defendant cannot be saddled with quantities of drags that he could not reasonably have foreseen. See United States v. Garcia, 954 F.2d 12, 15 (1st Cir.1992).

Different types of drugs affect the offense-level calculation in different ways. For instance, a defendant whose relevant conduct involved 30 kilograms or more of heroin would merit a BOL of 38, as would a defendant whose relevant conduct involved 150 kilograms of cocaine, or one whose relevant conduct involved 1.5 kilograms of cocaine base (crack cocaine). See USSG § 2Dl.l(e)(l) (Drug Quantity Table). The Santiago organization trafficked indiscriminately in heroin, powdered cocaine, and crack, and the sentencing guidelines contain an elaborate conversion formula that can be used in such cases. See USSG § 2D1.1, comment.- (n.10).

At the disposition hearing, the judge set the appellant’s BOL at 38, but without much in the way of elaboration. The appellant challenges this assessment. On the evidence, the judge easily could have found, by the requisite preponderanee-of-the-evidence standard, see Sklar, 920 F.2d at 110, that the appellant was a member of the Santiago organization, whose relevant conduct encompassed drag transactions occurring at the Arecibo and Corozal drop points. But the court did not reference any evidence to support an assessment of the volume of drags sold at either location, and the PSI Report contains no such quantification. While we may agree with the government that the Santiago organization did a substantial amount of narcotics business, and that the *780 totals necessary for a BOL of 38 (e.g., 1.5 kilograms of crack) seem attainable given the appellant’s role in the conspiracy, we cannot uphold a drug quantity calculation on the basis of hunch or intuition. See Sepulveda, 15 F.3d at 1199; Sklar, 920 F.2d at 113.

In this case, drug quantity dictated the appellant’s sentence in large part. In the absence of particularized findings to support the assigned BOL, we have no principled choice but to vacate the sentence and remand for further findings and resentencing. See Sepulveda, 15 F.3d at 1199; United States v. O’Campo, 973 F.2d 1015, 1026 (1st Cir.1992).

Conclusion

We need go no further. Although the appellant has raised a gallimaufry of arguments anent his conviction, all of them— including some that do not warrant discussion — are unavailing. For aught that appears, the appellant was fairly tried and justly convicted. A question lingers, however, as to the appropriateness of the appellant’s sentence. That question apparently turns on the issue of drug quantity, since the appellant’s other sentence-related arguments all are groundless. To enable this final question to be answered, we vacate the appellant’s sentence and remand for resentencing.

The appellant’s conviction is affirmed, his sentence is vacated, and the case is remanded for resentencing.

Notes

. The jury also found for the government on a count that sought criminal forfeiture. See 21 U.S.C. § 853 (1994). Because the appellant does not mount an independent challenge to this disposition, we abjure any further mention of it.

. At trial, José Nevarez, a police officer, described an incident in which the appellant was shot. Among other things, Nevarez testified that, immediately after the shooting, Marrero made a telephone call from his cellular telephone. He then refused to assist the police in gathering information about the perpetrators. This testimony corroborated other evidence that the Santiago organization was engaged in a "drug war" with a rival gang.

. The rule provides in pertinent part:

[T]he defendant may, in order to afford an opportunity to move to suppress evidence request notice of the government's intention to use (in its evidence in chief at trial) any evidence which the defendant may be entitled to discover under Rule 16....

. Indeed, the district court noted specially that a variety of factors, such as the unavailability of witnesses and sloppy prosecutorial work at the local level, may well have contributed to the dismissal.

. We emphasize that the district court, although permitting questions as to the appellant’s arrest and the circumstances thereof to show his participation in the drug-trafficking conspiracy and to corroborate the testimony of cooperating witnesses, precluded the government from introducing any evidence that local authorities charged or prosecuted Marrero.

. Withal, the court's decision to empanel four alternate jurors entitled the appellant to two additional peremptory challenges that he never received. See Fed.R.Crim.P. 24(c). But the appellant never objected to the number of challenges he was afforded anent the empanelment of the alternates and thus failed to preserve the right to raise this error on appeal. See United States v. Broadus, 7 F.3d 460, 463 (6th Cir.1993) (holding that a defendant's failure to object to the denial of his right peremptorily to challenge alternates constitutes a waiver of any right to appeal the issue); Carbo v. United States, 314 F.2d 718, 748 (9th Cir.1963) (holding that Rule 24(c) violations *777 not brought to the district court’s attention are forfeited). Moreover, since none of the alternates actually were called upon to serve as jurors, the error was patently harmless.

. Section 924(c)(1) provides in pertinent part that "[w]hoever, during and in relation to any crime of violence or drug trafficking crime ... uses or carries a firearm, shall, in addition to the punishment provided for such crime of violence or drug trafficking crime, be sentenced to imprisonment for five years

. We note, parenthetically, that the district judge recognized that he could have increased the BOL by three or four levels, rather than two, because of the organization’s extensiveness. We need not speculate why the court eschewed this course, as the government has not brought a cross-appeal.
