18 BACKGROUND

19 At trial, the government argued that Mack killed Francis in order to avoid 

20 being arrested. Although Mack was indicted on September 15, 2010, along with 

21 32 others, law enforcement could not locate him and turned to Breann Wynter, 

22 another defendant named in the indictment, for assistance. Wynter hoped that by 

23 helping the government locate Mack, she might avoid a ten-year mandatory 

24 minimum sentence. Wynter was dating Francis, Mack’s close friend. Wynter and 

4 Mack was acquitted of two counts of witness tampering by first-degree murder of Francis, 

in violation of 18 U.S.C. §§ 2, 1512(a)(1)(A), and 1512(a)(1)(C). 

5 Mack’s remaining arguments on appeal are addressed in a summary order filed 

simultaneously with this opinion.
4 No. 16-3734-cr

1 Francis, assuming that Mack understood that his arrest was inevitable, hoped that 

2 Mack would be amenable to the following proposal: in exchange for $1,000 or 

3 $1,500, Mack would tell Francis and Wynter where he would be at a specific time, 

4 so that Wynter could tell law enforcement where Mack could be found. Francis 

5 proposed this arrangement to Mack twice, but Mack neither accepted nor rejected 

6 it. Mack never gave Francis or Wynter the requested information. 

7 On December 21, 2010, at around 8:20 p.m., Keronn Miller, one of Mack’s 

8 associates, was riding in a car with Francis. Miller told Francis to pull over so 

9 Miller could urinate. Moments later, a masked gunman fired multiple shots from 

10 a Ruger 9mm firearm into the car. When Miller returned to the car, he found 

11 Francis shot but alive and on the phone with a 911 dispatcher. He then drove 

12 Francis to the hospital. Francis died from his injuries on January 15, 2011. Mack 

13 and Miller were indicted for conspiring to commit witness tampering by 

14 murdering Francis. In advance of Miller’s scheduled trial on that indictment, the 

15 government disclosed its witness list, which included Jernigan, another of Mack’s 

16 close friends. 

17 On a superseding indictment, the government offered evidence that while 

18 incarcerated at the Wyatt Detention Center in Rhode Island, Mack conspired to 

19 kill Jernigan to prevent him from testifying. The government relied heavily on 

20 testimony from Tyquan Lucien, who also was incarcerated at Wyatt and 

21 participated in the Jernigan conspiracy. Lucien told Mack that if Jernigan were

22 arrested, Jernigan might cooperate and testify against Mack. Mack responded, “[I] 

got to do something about it. Like he got to go.” 23 6 Lucien himself decided to do 

24 something about it. Because he was not able to get out of jail on bond to kill 

25 Jernigan, Lucien turned to his cellmate, who volunteered that “his boy” could kill 

Jernigan.7 26 Unbeknownst to Lucien, his cellmate was an FBI informant. The

5 No. 16-3734-cr

1 cellmate arranged for Lucien to meet “his boy,” who in fact was an undercover 

2 agent. When Lucien met with the agent in the Wyatt visiting area, he gave the 

3 agent Jernigan’s home address, which he had received from Mack. Some time 

4 later, Lucien told Mack, “I sent my peoples” (referring to the undercover agent),

“they came Friday,” so that Mack “could know everything’s a go.”8 5 During this 

6 conversation, Mack confirmed to Lucien that the address that Lucien had given to 

the agent was the right one.9 7 

8 On April 27, 2016, the jury convicted Mack on two charges of conspiracy to 

9 commit witness tampering by first-degree murder and on two firearms charges. 

10 On November 1, 2016, the district court sentenced Mack to life imprisonment for 

11 each conspiracy and the statutory maximum penalty of ten years’ imprisonment 

12 for each firearms conviction, all sentences to run concurrently. This appeal 

13 followed.

14 DISCUSSION

15 On appeal, Mack attacks his conviction and sentence, arguing primarily that 

16 the district court: (i) failed to instruct the jury on an essential element of his 

17 firearms offenses; (ii) erred in admitting hearsay declarations under Federal Rule 

18 of Evidence 804(b)(3); (iii) erred in admitting a summary chart under Federal Rule 

19 of Evidence 1006; and (iv) was not required to impose life sentences for Mack’s 

20 conspiracy convictions. None of these arguments has merit.

1 I. The Jury Instructions

2 At trial, the district court instructed the jury that to satisfy the mens rea

element for Mack’s firearms charges under 18 U.S.C. §§ 922(g)(1) and 924(a)(2),10 3

4 the government had to prove only “that the defendant knowingly possessed the 

firearm.”11 5 The district court did not instruct the jury that the government had to 

6 show that Mack knew he was a member of a class of persons forbidden to possess 

7 firearms by virtue of his earlier felony conviction. Relying on Rehaif v. United 

States,12 8 a case decided by the Supreme Court just last term, Mack challenges the 

9 adequacy of the jury instructions for his firearms conviction. Because Mack raises 

10 his challenge for the first time on appeal, we review for plain error, considering 

11 whether “(1) there is an error; (2) the error is clear or obvious, rather than subject 

12 to reasonable dispute; (3) the error affected the appellant’s substantial rights; and 

13 (4) the error seriously affects the fairness, integrity or public reputation of judicial 

proceedings.”13 14 

15 In Rehaif, the Supreme Court addressed whether a noncitizen had to know 

16 his immigration status to be convicted under 18 U.S.C. § 922(g)(5), which prohibits 

17 “an alien . . . illegally or unlawfully in the United States” from possessing a firearm. 

18 It held that to obtain any conviction under § 922(g), the government must prove 

19 that the defendant “knew he belonged to the relevant category of persons barred 

from possessing a firearm.”14 20 The Court determined that the district court’s jury 

21 instructions to the contrary were erroneous and remanded to allow the lower 

10 18 U.S.C. §§ 922(g) and 924(a)(2) bar various categories of persons, including felons, 

fugitives from justice, and individuals dishonorably discharged from the Armed Forces, from 

possessing firearms.

1 courts to decide whether the error was harmless. As in Rehaif, and as the 

2 government concedes, the district court’s jury instructions in Mack’s case were 

3 clearly erroneous in their omission of the government’s obligation to prove Mack’s

4 knowledge of his status as a former felon. 

5 Examining the question through the plain-error lens, Mack and the 

6 government agree that the first two prongs of plain-error review are satisfied.

7 They disagree, however, on the effect of those erroneous jury instructions. 

8 Accordingly, we focus on the third and fourth prongs of plain-error review.

9 In assessing the effect of the erroneous jury instructions on Mack’s 

10 substantial rights, we consider “the weight of [the] trial evidence bearing on the 

11 omitted element” and whether the omitted element was “essentially 

uncontroverted.”15 12 We ask whether we can conclude, beyond a reasonable doubt, 

that a properly-instructed jury would have returned the same verdict.16 13 In 

14 answering this question, we appropriately limit ourselves to the evidence actually 

presented to the jury.17 15 

16 To find Mack guilty of a violation of § 922(g)(1), a properly-instructed jury

17 would have to find, beyond a reasonable doubt, that Mack knew he was a person 

15 United States v. Gomez, 580 F.3d 94, 100–01 (2d Cir. 2009) (quoting United States v. Guevara, 

298 F.3d 124, 126–27 (2d Cir. 2002)). 

16 Id. at 101 (“To sustain the conviction, we must find that the jury would have returned the 

same verdict beyond a reasonable doubt.”) (citing United States v. Jackson, 196 F.3d 383, 386 (2d 

Cir. 1999)). Our conclusion would not differ depending on who bears the burden of persuasion 

in this appeal. Accordingly, we decline to resolve the parties’ disagreement over whether 

“modified plain error” or our standard plain-error review applies.

17 See Neder v. United States, 527 U.S. 1, 19 (1999) (in assessing “whether the jury verdict would 

have been the same absent the error . . . a court, in typical appellate-court fashion, asks whether 

the record contains evidence that could rationally lead to a contrary finding with respect to the 

omitted element”); see also United States v. Sepulveda, No. 18-cr-363 (RJS), 2019 WL 5704398, at *12 

(S.D.N.Y. Nov. 5, 2019) (declining to “‘engage in pure speculation . . . of what a reasonable jury 

would have done’ if facts adduced at sentencing had also been introduced at trial”).

1 convicted of a felony, or “a crime punishable by imprisonment for a term 

2 exceeding one year.” It is customary for a defendant in a case like Mack’s to 

3 stipulate to the existence of his prior felony in order to prevent its details

4 (including the duration of the sentence) from being placed before the jury. At trial, 

Mack entered into such a stipulation, 5 18 which did not mention the duration of his 

6 sentence or his knowledge of whether he had a felony conviction, and the 

7 government proffered no further evidence on his prior conviction or knowledge. 

8 The government now asks us to rely on Mack’s stipulation, as well as his

9 failure to contest scienter, to conclude that the jury, if properly instructed, would 

10 have still found Mack guilty. We acknowledge that, given the rights to appointed 

counsel, effective assistance of counsel,19 and due process,20 11 it is highly improbable 

12 that a person could be convicted of a felony without being aware that his possible 

13 sentence would exceed one year’s imprisonment. We also recognize that Mack 

14 and his counsel never suggested to the jury that Mack was unaware that his prior 

15 conviction carried a potential sentence of over one year’s imprisonment. This 

16 differs Mack’s case from United States v. Balde, where we found that the defendant 

17 might not have known his § 922(g)(5) qualifying status as “an alien . . . illegally or 

18 unlawfully in the United States” based on the legal “complexities” of the 

19 defendant’s immigration situation and how “hotly contested” scienter was at the 

district court.21 20 Still, we believe that the substantial-rights analysis in Mack’s case 

18 Mack’s stipulation reads, “[P]rior to December 21, 2010, Dominique Mack was convicted of 

a crime punishable by imprisonment for a term exceeding one year in Connecticut Superior 

Court, Judicial District of Hartford.” Appellant’s Amended Supplemental Br. at 2. 

19 See United States v. Gordon, 156 F.3d 376, 380 (2d Cir. 1998) (per curiam) (counsel’s failure to 

inform his defendant of “the full extent of his sentencing exposure upon conviction” before the 

defendant went to trial constituted ineffective assistance of counsel).

20 Caputo v. Henderson, 541 F.2d 979, 983 (2d Cir. 1976) (describing that the constitutional 

voluntariness of a guilty plea turns, in part, on whether the trial court informs the defendant of 

the maximum sentence possible).

21 943 F.3d 73, 97 (2d Cir. 2019).
9 No. 16-3734-cr

1 is a difficult one, given the paucity of factual development at trial pertaining to a 

2 question that was not discerned before Rehaif was decided. Accordingly, we 

3 decline to decide whether a properly-instructed jury would have found that Mack 

4 was aware of his membership in § 922(g)(1)’s class. Instead, we choose to resolve 

5 this case on the fourth prong of plain-error review, which examines whether not 

6 reversing would “seriously affect[] the fairness, integrity or public reputation of 

judicial proceedings”22 7 and which does not necessarily confine us to the trial 

8 record.

9 Under the circumstances, we do not think that rejecting Mack’s argument 

10 will seriously affect the fairness, integrity, or public reputation of judicial 

11 proceedings. To the contrary, we think that accepting it would have that effect. 

12 Because Mack stipulated to his § 922(g)(1) qualifying status, at trial he likely would 

13 have sought to exclude, and would have been successful in excluding, the details 

14 pertaining to his prior offense as unnecessary and prejudicial embellishment on 

his stipulation.23 15 We will not penalize the government for its failure to introduce 

16 evidence that it had but that, prior to Rehaif, it would have been precluded from 

17 introducing. Therefore, in the limited context of our fourth-prong analysis, we

18 will consider reliable evidence in the record on appeal that was not a part of the 

19 trial record: Mack’s presentence investigation report (PSR), a report offered to 

22 Nouri, 711 F.3d at 138 (internal quotation marks and alterations omitted) (quoting Marcus, 

560 U.S. at 262). 

23 See Fed. R. Evid. 403 (“The court may exclude relevant evidence if its probative value is 

substantially outweighed by the danger of . . . unfair prejudice”); see also Old Chief v. United States, 

519 U.S. 172, 192 (1997). Most defendants charged with violations of § 922(g)(1) avail themselves 

of Old Chief in order to keep the nature and details of their prior felony convictions from the jury. 

Thus, in many pre-Rehaif § 922(g)(1) cases, the trial record will contain limited evidence regarding 

the defendant’s knowledge of his felon status. Rehaif now tells us that the defendant’s knowledge 

of his felony status is an element of a § 922(g)(1) offense that the government must prove. Because 

defendants typically avail themselves of Old Chief when they have multiple or damning felony 

records, it should come as no surprise that a reviewing court, conducting plain-error review, will 

find that the fairness, integrity, or public reputation of judicial proceedings has not been affected, 

when considering evidence of the defendant’s felony status beyond just the trial record.
10 No. 16-3734-cr

1 Mack for correction and subsequently adopted and relied upon by the district 

2 court during sentencing. The PSR shows that Mack’s prior conviction, for the 

3 unlawful theft and alteration of a firearm, resulted in a total effective sentence of 

4 ten years’ imprisonment, with execution suspended after three years, which 

5 removes any doubt that Mack was aware of his membership in § 922(g)(1)’s class. 

6 Similarly, we have no doubt that, had the Rehaif issue been foreseen by the district

7 court, Mack would have stipulated to knowledge of his felon status to prevent the 

8 jury from hearing evidence of his actual sentence. Under all of the circumstances, 

9 it is plain to us that Mack has not satisfied the fourth plain-error prong. 

10 Therefore, the district court’s erroneous jury instructions did not rise to the 

level of reversible plain error.24 11

12 II. Admissibility of Farmer’s Testimony under Rule 804(b)(3)

13 Because Miller did not testify at trial, the government proffered testimony 

14 from Brandyn Farmer as to statements Miller made to Farmer about Francis’s

15 murder. Mack objected to this testimony, which covered Miller’s statements that 

16 Miller had lured Francis to the spot where he was shot, that Miller had been 

17 present when the shooting occurred, and that Mack was the shooter. After 

18 carefully hearing from both sides, the district court permitted the testimony for 

19 the truth of Miller’s statements under Rule 804(b)(3)’s hearsay exception for 

20 statements against penal interest. 

24 We note that numerous other circuits that have considered the Rehaif issue have likewise 

found no reversible error in these or similar circumstances. However, the other circuits have so 

decided based on the third prong of plain-error review. See, e.g., United States v. Conley, No. 19-

5168, 2020 WL 571324 (6th Cir. Feb. 5, 2020); United States v. Mancillas, 789 F. App’x 549, 550 (7th Cir. 

2020); United States v. Reed, 941 F.3d 1018, 1021–22 (11th Cir. 2019); United States v. Hollingshed, 940 

F.3d 410, 415–16 (8th Cir. 2019); United States v. Benamor, 937 F.3d 1182, 1188–89 (9th Cir. 2019).
11 No. 16-3734-cr

1 We review the district court’s Rule 804(b)(3) determination for abuse of 

discretion,25 2 and even if we find the district court’s determination to be in error, 

we will not reverse if the error is harmless.26 3 But before we can find the district 

4 court’s ruling harmless, we must be “able to conclude that the evidence would 

5 have been unimportant in relation to everything else the jury considered on the 

issue in question, as revealed in the record.”27 6 

7 Rule 804(b)(3) allows for a hearsay statement to be admitted “if the declarant 

8 is unavailable as a witness,” the statement is “so contrary to the declarant’s 

9 proprietary or pecuniary interest or had so great a tendency to invalidate the 

10 declarant’s claim against someone else or to expose the declarant to civil or 

11 criminal liability” that “a reasonable person in the declarant’s position would have 

12 made [the statement] only if the person believed it to be true,” and the statement

13 “is supported by corroborating circumstances that clearly indicate its 

trustworthiness.”28 14 On appeal, Mack argues that the district court erred in 

15 allowing Farmer’s testimony because (i) Miller was not an “unavailable” witness; 

16 (ii) even if Miller were “unavailable,” the government procured his unavailability; 

17 and (iii) the statements in question were not against Miller’s interest and were not 

18 credible. Although we share Mack’s concerns regarding a provision in Miller’s

19 plea agreement which Mack argues had the effect of procuring Miller’s

20 unavailability, we conclude that, even assuming there was error, any such error 

21 would not have been clear and would in any event have been harmless.

22 A. Miller was an “unavailable” witness.

1 Rule 804(b)(3) first requires that “the declarant whose statement is sought 

to be introduced be unavailable as a witness.” 2 29 When a witness properly invokes 

3 his Fifth Amendment right against self-incrimination, he is unavailable for the

purposes of Rule 804(a).30 4 

5 At issue in this case is the manner in which Miller’s Fifth Amendment right 

6 was invoked. On December 2, 2014, in a plea proceeding before the same district 

7 court, Miller’s counsel represented that Miller “would take the Fifth if he was 

called to testify.” 8 31 Again, on June 9, 2015, in a hearing related to Miller’s 

9 sentencing, Miller’s counsel stated to the district court that he had advised Miller 

10 to take the Fifth and that Miller had “indicated to [counsel] that he would heed 

that advice.”32 11 Ten months later, on April 14, 2016, the district court concluded

12 that “Mr. Miller would have exposure were he to answer questions about any 

13 involvement he might have, and his lawyers have represented to me in a public 

14 proceeding . . . that he would, in fact, invoke the Fifth Amendment if [he] were 

15 called. Based on my understanding of the facts, he would have a basis for doing 

so. And, therefore, I believe he does qualify as unavailable under Rule 804.”33 16 

17 A ruling regarding privilege “can be made . . . with or without the witness 

being haled into court.”34 18 In United States v. Williams, we addressed a situation in 

19 which the district court relied on representations of counsel regarding their clients’ 

20 intention to rely on their Fifth Amendment privileges rather than the clients’ direct

representations. 1 35 Counsel’s representations were provided to the district court

2 roughly one month before the district court determined that counsel’s clients were 

unavailable within the meaning of Rule 804(a).36 3 The only difference between 

4 Williams and Mack’s case is the amount of time between counsel’s representation 

5 that the declarant would assert his Fifth Amendment privileges and the district 

6 court’s determination of unavailability. The distinction between one month in 

7 Williams and ten months in Mack’s case is not material. While it is possible that 

8 Miller could have changed his mind about testifying, there is no suggestion in the 

9 record that he did. The district court did not abuse its discretion in determining 

10 that Miller was unavailable for the purposes of Rule 804(a). 

11 B. The district court did not clearly err in failing to conclude that the 

12 government procured Miller’s unavailability.

13 Mack next argues that, even if Miller were unavailable, Miller’s statements 

14 were nonetheless inadmissible under Rule 804(a) because the government 

impermissibly procured Miller’s unavailability through his plea agreement.37 15 

16 Mack raises this argument for the first time on appeal, and so we can correct any 

17 error only if Mack demonstrates “(1) error that (2) is clear or obvious under current 

18 law; (3) affects his substantial rights, which generally means affects the outcome

1 of the district court proceedings; and (4) seriously affects the fairness, integrity, or 

public reputation of judicial proceedings.”38 2

3 Miller’s plea agreement included an unusual provision specifying that the 

4 agreed-upon sentencing range would not be binding if Miller were to testify 

5 “about the subject matter which forms the basis of the superseding indictment in 

6 this case, and provide testimony inconsistent with or in addition to the facts proffered 

and agreed to by the defendant as part of the plea colloquy.”39 7 The plea agreement 

8 specified facts regarding the Francis shooting, including that Miller enticed Francis 

9 to a location where he knew he would be shot, “knowing and intending that 

10 another person or persons who the defendant assisted wanted to prevent a person 

11 from communicating with federal law enforcement and/or to prevent the 

attendance of a person at an official federal proceeding.”40 12 

13 Importantly, Miller’s plea agreement did not say anything about Mack

14 being the shooter or otherwise identify the shooter. Although the statements to 

15 Farmer that Miller saw Mack shoot Francis or knew that Mack was the shooter 

16 were not inconsistent with the facts specified in the plea agreement, they included

17 additional facts. Accordingly, Miller could not have presented this testimony 

18 without breaching his plea agreement and jeopardizing the agreed-upon 

19 sentencing range, thereby motivating him to invoke his Fifth Amendment rights 

20 and rendering him unavailable to testify.

21 We are deeply troubled by the government’s use of such a provision, which

22 went beyond the typical requirement that Miller’s potential future testimony be 

23 truthful and instead significantly constricted such testimony by requiring that it 

24 be identical to the facts elicited in his proffer. Nevertheless, because the objection

1 was not raised below and our review is limited to plain error, we need not reach 

2 the question of whether the government procured Miller’s availability in this case.

3 Here, Miller could have faced exposure justifying the invocation of the Fifth 

4 Amendment even absent the government’s use of the contested provision; in these 

5 circumstances, the district court did not commit a clear or obvious error by failing 

6 to exclude the evidence on the basis that the government procured Miller’s 

7 unavailability. Moreover, as discussed below, any error with respect to the district 

8 court’s Rule 804 analysis would have been harmless.

9 C. Miller’s statements about which Farmer was permitted to testify were 

10 against Miller’s interest and were credible.

11 We are likewise unpersuaded by Mack’s argument that the district court 

12 incorrectly found Miller’s statements to be statements against his interest and 

13 “supported by corroborating circumstances that clearly indicate [their]

trustworthiness.”41 14 The district judge did not abuse his discretion in reaching 

15 either of these conclusions.

16 I. Miller’s statements were against his penal interest.

17 Mack first argues that Miller’s statements to Farmer were not against his 

18 penal interest because it was in Miller’s interest to falsely implicate Mack. 

19 However, “[w]hether a challenged statement is sufficiently self-inculpatory can 

20 only be answered by viewing it in context. Thus, this determination must be made 

on a case-by-case basis.”42 21 A statement is against penal interest if “a reasonable 

22 person in the declarant’s shoes would perceive the statement as detrimental to his 

or her own penal interest.”43 23 “This exception rests on the notion that ‘reasonable

Cir. 2004).
16 No. 16-3734-cr

1 people, even reasonable people who are not especially honest, tend not to make 

self-inculpatory statements unless they believe them to be true.’”44 2 

3 The district court considered each admitted statement individually and 

4 provided specific reasons for why each one incriminated Miller. Principally, the 

5 district court explained that Miller’s statement that he saw Mack pull the trigger, 

6 if “elicited after or together with Miller’s statement that he drove Francis to 

7 Sigourney Street so that Mack could shoot Francis . . . does inculpate Miller 

8 because it tends to show that the conspiracy described in the first statement was 

9 actually carried out and that the conspiracy actually caused the death of Ian 

Francis.”45 10 Because statements are self-inculpatory when they describe acts the 

declarant and defendant “committed jointly,” 11 46 we agree with the district court.

12 We therefore conclude that the district court did not abuse its discretion in finding 

13 the statements to be against Miller’s penal interest. 

14 II. Miller’s statements were supported by corroborating circumstances.

15 Mack next argues that Miller’s statements were not “supported by 

16 corroborating circumstances that clearly indicate [their] trustworthiness,” as 

17 required by Rule 804(b)(3). “We take this [requirement] to mean that the inference 

18 of trustworthiness from the proffered ‘corroborating circumstances’ must be 

strong, not merely allowable.”47 19 

20 Here, Miller’s statements were corroborated by the testimony of Anthony 

21 Brinson, Francis’s nephew, as well as by Miller’s plea agreement and colloquy. 

22 Brinson stated that Francis told him, after he was shot, that “Miller told Francis to

1 pull over on Sigourney Street so that Miller could urinate” and that “Miller got out 

2 of the car, walked by a masked man – and made eye contact with him – before the 

masked man began shooting into Francis’s vehicle.” 3 48 Miller’s statements to

4 Farmer were also consistent with Miller’s representations in his plea agreement 

5 and colloquy. 

6 Mack attacks Farmer’s credibility on the basis of his past criminal 

7 convictions and as a “jailhouse informant” who only remembered key aspects of 

8 his testimony when being prepared for trial. But Farmer’s credibility was for the 

9 jury to assess. Such credibility attacks have no bearing on whether Miller’s

statements to Farmer were trustworthy, the appropriate Rule 804(b)(3) inquiry.49 10 

11 For these reasons, the district court did not abuse its discretion in determining that 

12 Miller’s statements were supported by corroborating circumstances that clearly 

13 indicate their trustworthiness.

14 D. Any error by the district court in applying Rule 804 would have been

15 harmless.

16 Even if the district court had erred in its Rule 804 analysis, we find that such 

17 an error would have been harmless. To find the admission of Miller’s statements 

18 harmless, we must be “able to conclude that the evidence would have been 

19 unimportant in relation to everything else the jury considered on the issue in 

question, as revealed in the record.”50 20

804(b)(3) purposes because “[a]ssessing the credibility of an in-court witness is the role of the 

jury”).

1 Like Farmer’s recounting of Miller’s statements, compelling testimony from 

2 Lucien supported the conclusion that Mack participated in the conspiracy to 

3 murder Francis. Lucien testified about time spent with Mack, Jernigan, and 

4 another man the day before the Francis shooting. Specifically, he said that Mack 

was angry with Francis because Francis and Wynter were “trying to turn him in”51 5

and that Mack said Francis “got to go.”52 6 Lucien testified further that, in an effort 

7 to gain Mack’s respect, Lucien offered to “kill Ian Francis for [Mack],” even though 

Lucien did not know who Francis was.53 8 Mack “laughed and he said [Jones] going 

9 to do it”; Mack said that Lucien should not be involved because he would be “too

hyper” and “might fuck up.”54 10 Lucien also testified that Mack instructed Jernigan 

11 to get a duffel bag from the closet and that Mack pulled a 9mm Ruger gun out of 

12 the duffel bag. 

13 It matters not that Mack told the group that Jones would be the shooter,

14 whereas Miller said the shooter was Mack. Either way, Mack conspired to murder 

15 Francis. Mack’s conviction for conspiracy to murder Francis was well-supported 

16 by Lucien’s testimony and independent of Miller’s statements. Thus, even 

17 assuming that the district court erroneously admitted Farmer’s testimony 

18 regarding Miller’s statements, the error was harmless.

19 III. Admissibility of Government Exhibit 65

20 Mack challenges the admissibility of government exhibit 65 (“GE 65”), a 

21 summary chart of phone bills pertaining to phone calls and text messages from 

22 December 21, 2010. The chart, entitled “Mack, Miller, Francis, Jones, and Jernigan 

23 Timeline, 21 December 2010,” depicted the fact of certain communications

1 between the five men on the night that Francis was shot. It identified each man by 

2 his name and picture and indicated whether each communication was a call or 

3 text, the time of the communication, and who initiated it. The summarized phone 

4 bills did not identify Mack, Miller, Francis, Jones, or Jernigan by name or image, 

5 but additional evidence in the record linked these men to the phone numbers 

6 appearing on the bills.

7 GE 65 was admitted as substantive evidence pursuant to Rule 1006, which 

8 allows a party to “use a summary, chart, or calculation to prove the content of 

9 voluminous writings, recordings, or photographs that cannot be conveniently 

examined in court.”55 10 We review the district court’s decision to admit the 

government’s summary chart for abuse of discretion.56 11 

12 On appeal, Mack argues that GE 65 was not admissible under Rule 1006

13 because it summarized at most eight pages of recordings, did not specify the 

14 length of each call or the phone numbers of the originating and receiving calls, was 

15 “highly selective” in terms of which calls it included, and included evidence 

16 obtained from FBI experts and not the phone bills. But even eight pages of phone 

17 bills can contain hundreds of calls and text messages, and this information would 

18 have been difficult for the jury to synthesize and evaluate without the aid of a 

19 summary. A summary need not include all the information that appears on a

20 phone bill, such as the duration of each call, if particular kinds of information are

21 not relevant and are either uniformly included or uniformly excluded. Although 

22 the summary included some information that was not on the phone bills, such as 

23 the name of the man associated with each phone number, this additional 

24 information was already admitted into evidence through other sources, and 

25 defense counsel was free to cross-examine the FBI agent who made the summary 

26 chart.

1 Mack also objects to the pictures of Mack, Miller, Francis, Jones, and 

2 Jernigan that were included in GE 65, arguing that they looked like “mug shots” 

3 and “made their subjects look like thugs.” Appellant’s Br. at 67. Although at least 

4 one of the pictures was a booking photograph, Mack did not alert the district court 

5 to any potential prejudice these pictures might cause. The district court focused 

6 only on whether the pictures had been produced to the defense. Based on this

7 record, we discern no basis to hold that the possible prejudice from the pictures 

8 outweighed GE 65’s probative value in clarifying the timeline of calls and texts 

9 revealed in the phone bills. Therefore, in no respect did the district court abuse its 

10 discretion by admitting GE 65. In any event, had there been error in admitting the 

11 chart, it was harmless. GE 65 was admitted to prove the Francis murder 

12 conspiracy. As discussed, witness testimony sufficiently supported Mack’s 

13 conviction of conspiracy to murder Francis.

14 IV. Sentencing Issues

15 Mack was convicted of two counts of conspiracy to commit witness 

16 tampering by first-degree murder, in violation of 18 U.S.C. § 1512(k). Section

17 1512(k) provides that those convicted of conspiracy to commit witness tampering

18 “shall be subject to the same penalties as those prescribed for the offense the 

19 commission of which was the object of the conspiracy.” The district court imposed 

20 a life sentence for each conspiracy conviction after concluding that the statutorily

21 prescribed penalty for either conspiracy to commit or committing witness 

22 tampering by first-degree murder is death or life imprisonment. 

23 First, Mack challenges the district court’s statutory analysis, arguing that a 

24 life sentence is not available against defendants who conspire to commit but 

25 ultimately are not responsible for first-degree murder. We disagree. Section

26 1512(k) instructs that a conspirator is subject to the same penalty as that prescribed 

27 for the substantive offense that was the “object” of the conspiracy. The object of a 

28 conspiracy to commit witness tampering by first-degree murder is, 

29 unsurprisingly, the commission of witness tampering by first-degree murder. 
21 No. 16-3734-cr

1 Committing witness tampering by killing or attempting to kill an individual is 

2 prohibited by 18 U.S.C. § 1512(a)(1) and punishable in accordance with 18 U.S.C. 

3 § 1512(a)(3). Section 1512(a)(3) specifies that the penalty for a “killing” is “the 

4 punishment provided in sections 1111 and 1112.” In turn, 18 U.S.C. § 1111 

5 specifies that the penalty for first-degree murder is “death” or “imprisonment for 

6 life.” Because § 1512(k) adopts the penalty for “the offense the commission of 

which was the object of the conspiracy,”57 7 and because the penalty for committing 

8 witness tampering by first-degree murder is death or life imprisonment, the 

9 district court did not err in determining that it was required to sentence Mack to

10 the statutory minimum of life imprisonment. 

11 Second, Mack argues that the district court erroneously increased Mack’s 

12 sentence “by making its own factual finding that Mack was responsible for a 

13 killing.” Appellant’s Br. at 78. But the district court did not do that. Rather, it was 

14 the jury that determined that Mack had conspired, with respect to both Francis 

15 and Jernigan, with the object of committing witness tampering by first-degree 

murder.58 16 Therefore, this challenge is without merit.

17 Third and finally, Mack argues that his life sentence violates the Eighth 

18 Amendment’s prohibition against cruel and unusual punishment. Highlighting 

19 cases that overturned life sentences imposed on juvenile offenders, Mack submits

20 that “the constitutional imperative of individualized sentencing should be 

21 extended to those who face sentences of life in prison with no possibility of release 

22 for the crime of entering into conspiracies that have resulted in no physical harm.” 

23 Appellant’s Br. at 79–80. The cases that Mack cites, however, turned on the fact 

24 that the defendant was a juvenile. In Graham v. Florida, for example, the Supreme 

25 Court held that the Eighth Amendment prohibits certain life sentences for juvenile 

57 18 U.S.C. § 1512(k) (emphasis added).

58 “The jury was also instructed that to convict on both Count One and Count Four they had 

to find that the type of murder that was the object of the conspiracy was first degree murder. No 

one objected to these instructions.” App’x at 270.
22 No. 16-3734-cr

1 offenders because “life without parole sentences for juveniles convicted of 

2 nonhomicide crimes [are] as rare as other sentencing practices found to be cruel 

3 and unusual” and “developments in psychology and brain science continue to 

4 show fundamental differences between juvenile and adult minds,” lessening 

juveniles’ culpability and deservingness of “the most severe punishments.”59 5 

6 Mack, an adult when he committed his crimes, does not marshal any comparable

7 data or moral reasoning in his Eighth Amendment argument. Although life 

8 imprisonment is inarguably a stiff penalty, this alone does not offend the Eighth 

9 Amendment. We agree with the district court that the appropriateness of Mack’s 

10 mandatory penalty of death or life imprisonment is a policy question for Congress

11 and not a constitutional question for the courts.

13 For these reasons, and for those set forth in the accompanying summary order, the 

14 judgment of conviction and sentence are AFFIRMED.
