                      _________________________

                               (May 3, 2006)

Before CARNES, WILSON and PRYOR, Circuit Judges.

PRYOR, Circuit Judge:
      This appeal by Cesar Garcia and Hector Nunez presents two main issues.

The first issue is whether, under the Sixth Amendment as interpreted in Crawford

v. Washington, 541 U.S. 36, 124 S. Ct. 1354 (2004), the district court erred by

permitting an expert witness to explain that he had relied upon the out-of-court

statement of a drug trafficker who testified at trial to the same statement. The

second issue is whether, under Federal Rule of Evidence 703, the district court

abused its discretion by permitting the expert witness, an experienced law

enforcement officer, to explain that, in determining the meaning of coded

language, he had relied upon the out-of-court statement of the drug trafficker. We

conclude that the Sixth Amendment does not prohibit the admission of an out-of-

court statement when the declarant testifies at trial to the same statement, and the

district court did not abuse its discretion in admitting the testimony of the expert

witness whose expertise included debriefing drug traffickers about their use of

coded language. We also conclude that sufficient evidence supported Garcia’s and

Nunez’s convictions for knowingly participating in a drug trafficking conspiracy,

sufficient evidence supported Garcia’s conviction for possession of a firearm in

furtherance of a drug trafficking crime, and the district court was not required to

hold a second hearing to determine whether Garcia’s lawyer should have been

disqualified due to a conflict of interest. We affirm.



                                           2
                                I. BACKGROUND

      Our decision in a related appeal, United States v. Molina, ___ F.3d ___, No.

04-13114 (11th Cir. Mar. 24, 2006), addressed several facts that also are relevant

to this appeal. On September 19, 2002, in the course of investigating a major drug

trafficking organization, agents of the Drug Enforcement Agency executed a

search warrant for the residence at 1131 Vermillion Lane near Atlanta in Georgia.

The agents found Garcia and his common-law wife, Eliany Molina, in an upstairs

bedroom. That bedroom, with the adjoining bathroom, contained substantial

evidence of a drug trafficking conspiracy. The evidence in the bedroom included a

bag containing 14.3 grams of cocaine on the floor, a digital scale on top of a

dresser, and a handgun in the open drawer of a nightstand next to the bed. The

evidence in the adjoining bathroom included a laundry hamper with a bag

containing 25.1 grams of cocaine and another digital scale, covered by clothes.

The agents also found evidence in the bedroom closets: one closet contained a

large blue garbage bag of bundled U.S. currency; the other closet contained a shoe

box of bundled U.S. currency. The garbage bag contained the bulk of the nearly

$300,000 that the agents seized from Garcia’s residence.

      The agents arrested Garcia, Molina, and Carlos Garza. Molina is the sister-

in-law of Garza. She also is the sister-in-law of Sebastian Cuevas, the purported



                                          3
ringleader of the drug trafficking organization.

      The next day, September 20, DEA agents arrested Hector Nunez at a

residence in Atlanta. The agents seized Nunez’s cell phone. Nunez stated he was

from Houston and admitted that Cuevas was his cousin. Nunez explained that he

traveled from Houston to Atlanta buying and selling cars, and Nunez denied that he

was involved in drug trafficking.

      A month before Nunez was arrested, the government had used a wiretap to

record three conversations between Cuevas and a speaker at the cell phone that the

agents would later seize from Nunez when they arrested him. Transcripts of two of

these three conversations contain coded references to drug trafficking. In the

conversation recorded on August 18, the speaker at Nunez’s phone asks Cuevas,

“What have you heard about [STUTTERS] ‘Ruthie’?” Cuevas responds, “Uh, that

she was there at . . . she is still down there in McAllen.” The unidentified male

responds, “Look uhm, I spoke to the lady . . . about the number I gave you

yesterday. . . . And she was telling me that if you want, uh, she can send it over . . .

tomorrow at dawn.” The unidentified male later says, “the truck driver is going to

call her back in a little while, to see if she has anything.” A few lines later, Cuevas

tells the unidentified male, “Your shirts will be ready for tomorrow afternoon.” In

the conversation recorded three days later, on August 21, the speaker at Nunez’s



                                            4
phone says, “I’m running around, trying to find the guy of the [STUTTERS] shirts.

. . . Uhm, I’m looking for him so that I don’t have the . . . the shirts here with me,

you understand?”

      The government also recorded, on August 20 and 22, 2002, two other calls

to or from Cuevas in which the second number was not identified. In the

conversation recorded on August 20, Cuevas asks the unidentified female who

answers the phone, “Yes, hello. Excuse me, is that guy, Hector, there?” The

unidentified female says, “Uh . . . he’s asleep because he just arrived from

Houston.” Cuevas says, “Oh! Yes, yes, yes.” The unidentified female then

notifies the male referred to as Hector, who takes the phone and says, “Hello?”

Cuevas says, “What’s up, cuz . . . ? Did I wake you up?” Hector replies, “Cuz . . .

how are you?” Cuevas asks, “At what time did you arrive?” Hector replies, “Just

a little while ago. . . . I brought Ruthie from over there.” Cuevas asks, “You

already brought it []? . . . Well . . . it was about time, right?” Hector says, “Yeah

man [unintelligible] he didn’t . . . He didn’t want to come over here, up here.”

After several lines of conversation, Hector says, “Yes, uhm, I went to . . . pick him

up there in uhm . . . in San Antonio.” A few lines later Cuevas asks, “And did he

come with, and did he come with the lady that you were talking about?” Hector

replies, “No, the . . . he came with the same . . . the same ones from, from . . .



                                            5
others, man. Some others that . . . .” Cuevas asks, “Other people?” Hector says,

“Yes, they were able to get them.” Cuevas asks, “But did they, did they bring it

over alright, finally?” Hector says, “Yes. Uh, it did get there alright. . . . It took

them an hour and a half to put it inside. . . . It’s just that I had to go pick them up

really far away, and I just got in now. I was up all night.” Cuevas says, “Yes, I

can imagine.”

       The conversation recorded on August 22 is between Cuevas and an

unidentified man. Neither speaker uses the word “Hector” and Nunez’s phone was

not linked to this call. In this conversation, the unidentified man tells Cuevas, “I’m

still . . . holding some for you,” and later says, “I’d like to go bring those shirts

over here for you once and for all, so I can have them here, but I say, ‘Well what,

what are they going to be doing just hanging here?’” The unidentified man also

describes how “a cousin called me . . . He needed one [] shirt, but that . . . he wants

two [] days . . . . he said that he’s . . . [unintelligible] jump today, you know what I

mean?” The unidentified man later says, “I don’t want to . . . grab the shirts and

then, they end up wearing them and then they say no. . . . I’d be letting you down

even more, and that’s what I don’t want.”

       On December 16, 2003, a grand jury returned an amended indictment that

charged 14 defendants with a variety of drug-related crimes. The indictment



                                            6
charged Garcia and Nunez with conspiracy to possess with the intent to distribute,

and to distribute, at least 5 kilograms of cocaine and at least 500 grams of

methamphetamine. See 21 U.S.C. §§ 846, 841(b)(1)(A)(ii), (viii). The indictment

also charged Garcia with possession of cocaine with the intent to distribute, see id.

§ 841(a)(1), and possession of a firearm in furtherance of a drug trafficking crime,

see 18 U.S.C. § 924(c)(1)(A)(i).

      An attorney, Derek Wright, sought to represent Garcia, Molina, and Garza.

The government filed a pretrial motion to disqualify Wright because his

representation of multiple defendants created the potential for a conflict of interest.

Garcia and Molina filed a brief opposing the disqualification of Wright.

      In their brief, Garcia and Molina stated that “Wright met with each

Defendant and explained the subject matter of conflict of interests, both actual and

potential, with all three Defendants.” According to Garcia and Molina, “All three

Defendants indicated that there was no conflict of interest or position that was

antagonistic to the other in either a trial issue or plea negotiation issue.” Garcia

and Molina reported that “all three Defendants executed waiver of conflict of

interest and an election to have Derek M. Wright represent all three.” Garcia and

Molina also stated that Wright would withdraw from representation of Garza.

Garcia and Molina stated that “Garcia strongly desires that Derek M. Wright



                                           7
represent him and his wife.”

      Garcia and Molina filed with the court signed waivers of conflicts of

interest. Garcia and Molina each stated in individual waivers that they did not

believe that there were “any conflicts of interest which would cast doubt upon or

interfere in any way with Derek M. Wright fully representing my legal interests.”

Garcia and Molina also each stated, “In the event that a conflict of interest, an

appearance of a conflict of interest, or the possibility of a conflict of interest should

arise, I hereby waive any objection to Derek M. Wright representing me in the

above referenced matter.”

      On December 10, 2003, a magistrate judge held a hearing on the matter of

Wright’s dual representation. The magistrate judge asked Garcia, “[W]ho do you

want to be your attorney?” Garcia replied, “Derek Wright.” The magistrate judge

asked Molina if she wanted to be represented by Mr. Wright. Molina answered,

“Yes.” The magistrate judge then stated, “There is, at the very least, a potential

conflict of interest . . . and I’m gonna try to explain some of that in a way that the

defendants can understand.” The magistrate judge invited the defendants to notify

her “if at any time you want to speak with me privately, that is without anyone else

present.” The magistrate judge confirmed that Garcia was fluent in English,

Molina understood the court proceedings through an interpreter, and neither Garcia



                                            8
nor Molina had used drugs or alcohol or taken medicine or pills in the past 24

hours.

         The magistrate judge explained how a conflict of interest could arise in plea

bargaining, the exercise of peremptory challenges to jurors, direct examination at

trial, and sentencing. The magistrate judge told Garcia and Molina “that money or

your ability to hire an attorney should not enter into your decision as to whether

you both want to proceed with the same attorney. You are entitled to a very

qualified attorney even if you cannot afford an attorney.” The magistrate judge

asked Garcia and Molina individually whether they wanted to speak to an

independent counsel, at no cost, “about the wisdom of going forward with the same

attorney.” Each defendant answered “no.” The magistrate judge asked Garcia and

Molina individually whether, “knowing everything that I’ve said, do you want to

continue with Mr. Wright as your attorney?” Each defendant answered “yes.” In

an order the next day, the magistrate judge denied the government’s motion to

disqualify Wright from representing both Garcia and Molina.

         The government made its cases against Garcia and Nunez in one trial. The

case against Garcia consisted primarily of the testimony of the agents who had

searched his residence, the evidence seized in that search, and expert testimony

about drug trafficking organizations. As the testifying officers explained and



                                            9
several exhibits illustrated, the evidence seized in the search of Garcia’s bedroom

and adjoining bathroom included two bags of cocaine, a digital scale, a digital

scale with cocaine residue, a firearm in the open drawer of a nightstand, a shoe box

of bundled U.S. currency, and a large blue garbage bag with the bulk of the nearly

$300,000 found in the house. In addition to the physical evidence and fact

witnesses, the government also proffered DEA Special Agent Keith Cromer as an

expert witness in the organization and structure of Mexican drug trafficking

organizations, including the use of coded language and the manufacture,

distribution, and packaging of narcotics.

      The government tendered Cromer as an expert witness on the basis of

several factors. Cromer had been a DEA agent since 1999. Cromer had attended a

16-week training course at the DEA academy that included executive techniques,

legal aspects of drug offenses, interviewing and interrogations, drug identification,

the operation and structure of drug trafficking organizations, and how those

organizations transport and distribute drugs. Cromer had been involved in at least

50 drug investigations. Eighty-five to ninety percent of those investigations had

involved Mexican drug organizations and, in 12 of those cases, Cromer had been

the “case agent.” Cromer also had participated in numerous wiretap investigations.

Cromer explained that, on the basis of his training and experience, he was familiar



                                            10
with the organization and structure of Mexican drug trafficking organizations. He

also explained that he was familiar with the coded language that some drug

trafficking organizations use and how drug trafficking organizations manufacture,

package, and distribute methamphetamine and cocaine. The district court

permitted Cromer to testify as an expert witness.

      Cromer testified about how drug trafficking organizations are divided into

functional components that include, among others, transportation, distribution,

collection of drug proceeds, and money laundering. Cromer testified that drug

trafficking organizations often use separate “stash houses” to store drugs and drug

proceeds. Cromer explained that drug traffickers typically stash drug proceeds in

houses occupied by residents the drug traffickers trust, like longtime friends or

family members. Cromer testified that drug traffickers use scales to weigh and

package drugs for distribution. Cromer also testified that drug traffickers often

possess weapons “for protection from other drug traffickers and from law

enforcement. They . . . may have them at the residence where they are going to

store the drugs or they store the money.”

      Cromer also testified about how drug traffickers use coded language to refer

to drugs. Cromer testified that “the majority of time different drug traffickers use

the same coded language that you would hear in one investigation to another



                                            11
investigation.” Cromer explained the meaning of several code words. Cromer

testified that the term “shirts” is used as a substitute for the word “cocaine,” and

sometimes for “methamphetamine” too. Cromer testified that the word “lady”

refers to “cocaine” and he believed the word “Ruthie” means drugs. Cromer also

explained that “McAllen” is a city in Texas “from where the drugs are smuggled

from Mexico into the United States” and the word “trailer” refers to “a tractor

trailer[,] which is one of the common forms of how to transport drugs from

McAllen, Texas, to Atlanta.” The jury heard each of the recorded conversations in

which the government alleged that Nunez used coded language to discuss drug

trafficking with Cuevas.

      Cromer explained that cooperating informants often help investigators

establish the meaning of coded language. Cromer explained that, to determine the

meaning of coded language, investigators rely upon interviews with arrested

suspects and information gathered by surveillance and corroborated by seizures.

On redirect examination, Cromer testified that, in this case, a cooperating

defendant named Antonio Mojica, who had worked for Sebastian Cuevas and

talked with him by phone, had told Cromer that the word “t-shirts” meant

“cocaine.” When Garcia’s attorney objected to Cromer testifying about what

Mojica had told him, the government stated that, because the defendants had



                                           12
challenged the basis of Cromer’s expert opinion, Cromer could explain the sources

he had used to form his opinion. The district court noted its discretion under

Federal Rule of Evidence 703 and admitted the testimony.

      Mojica also testified at trial. Mojica admitted he had used code words to

describe drugs. Mojica testified that he and Cuevas had used the word “shirts” in

talking about drugs, and “an ounce of cocaine is one shirt.”

      After the government presented its case, Garcia and Nunez each moved for a

judgment of acquittal. The district court reserved its ruling on the motions.

      Nunez did not present evidence, but Garcia decided to testify. Garcia

testified that the drugs in his bedroom came from a man called Marcos, the same

man who had asked Garcia to store the garbage bag of money that the agents found

in Garcia’s closet. Garcia testified that he was addicted to cocaine, and he planned

to use the cocaine found in his bedroom with his friends. Garcia testified that the

drugs belonged to him, not Molina, and Molina did not know about the drugs or

the money in the garbage bag. Garcia admitted suspicions that Marcos was a drug

dealer and the garbage bag contained drug proceeds. Garcia admitted he was

concerned someone might try to steal the money Marcos gave him, but denied he

would have used the firearm to protect it. Garcia also recounted how initially he

had told the arresting agents he had no firearm, but then directed them to the



                                          13
firearm in the open drawer of the nightstand. Garcia admitted that he had lied “a

little bit” when the DEA agents questioned him upon arrest.

      On January 28, 2004, a jury found Garcia and Nunez guilty of the charged

offenses. Garcia and Nunez each moved for judgments of acquittal. The district

court denied their motions, and Garcia and Nunez appealed.

                           II. STANDARD OF REVIEW

      We apply three standards of review to Garcia’s and Nunez’s challenges.

First, when a district court is asked to decide whether the presumption in favor of a

defendant’s counsel of choice is overcome by actual conflict or serious potential

for conflict, the Supreme Court has instructed that the district court has “broad

latitude . . . in making this decision” and “[t]he evaluation of the facts and

circumstances of each case . . . must be left primarily to the informed judgment of

the trial court.” Wheat v. United States, 486 U.S. 153, 163, 164, 108 S. Ct. 1692,

1699, 1700 (1988). Second, we review evidentiary rulings, including whether to

admit expert testimony, for abuse of discretion. See Quiet Tech. DC-8, Inc. v.

Hurel-Dubois UK Ltd., 326 F.3d 1333, 1339-40 (11th Cir. 2003); United States v.

Range, 94 F.3d 614, 620 (11th Cir. 1996). Third, we review de novo whether

evidence is sufficient to sustain a conviction. See, e.g., United States v. Williams,

144 F.3d 1397, 1401-02 (11th Cir. 1998). “In considering a motion for the entry of



                                           14
a judgment of acquittal, a district court ‘must view the evidence in the light most

favorable to the government, and determine whether a reasonable jury could have

found the defendant guilty beyond a reasonable doubt.’” United States v. Miranda,

425 F.3d 953, 959 (11th Cir. 2005) (quoting United States v. Sellers, 871 F.2d

1019, 1021 (11th Cir. 1989)). “It is not necessary for the evidence to exclude

every reasonable hypothesis of innocence or be wholly inconsistent with every

conclusion except that of guilt . . . .” United States v. Bell, 678 F.2d 547, 549 (5th

Cir. Unit B 1982) (en banc); see Sellers, 871 F.2d at 1021. “The jury is free to

choose between or among the reasonable conclusions to be drawn from the

evidence presented at trial, and the court must accept all reasonable inferences and

credibility determinations made by the jury.” Sellers, 871 F.2d at 1021 (internal

quotations and citations omitted).

                                 III. DISCUSSION

      Our discussion is divided into four parts. We first discuss the admission of

Special Agent Cromer’s expert testimony, which also raises the two main issues in

this appeal: whether the district court erred under the Sixth Amendment or abused

its discretion when it admitted Cromer’s testimony about the out-of-court

statement of a drug trafficker. We then address whether the district court abused

its discretion by not holding a second hearing on whether to disqualify Garcia’s



                                          15
counsel due to a conflict of interest. We next address whether sufficient evidence

supported the convictions for conspiracy. We end with a discussion of whether

sufficient evidence supported Garcia’s conviction for possession of a firearm in

furtherance of a drug trafficking crime.

       A. The District Court Properly Admitted Cromer’s Expert Testimony.

      Garcia and Nunez raise three issues with Special Agent Cromer’s expert

testimony. First, Garcia argues that the district court abused its discretion under

Federal Rules of Evidence 702 and 403 by permitting Special Agent Cromer to

testify as an expert witness. Second, Garcia and Nunez argue that the district court

erred under the Sixth Amendment by permitting Cromer to testify about the

hearsay statement of a cooperating conspirator. Third, Nunez argues that the

district court abused its discretion under Federal Rule of Evidence 703 when it

permitted Cromer to testify about the hearsay statement of a cooperating

conspirator. Each argument fails.

    1. The District Court Did Not Abuse Its Discretion by Permitting Cromer to
                           Testify as an Expert Witness.

      Federal Rule of Evidence 702 permits expert testimony if “specialized

knowledge” will help the jury “to understand the evidence or to determine a fact in

issue.” Fed. R. Evid. 702. “[A] witness [may be] qualified as an expert by

knowledge, skill, experience, training, or education.” Id. “The operations of


                                           16
narcotics dealers are a proper subject for expert testimony under Rule 702,” United

States v. Ginsberg, 758 F.2d 823, 830 (2d Cir. 1985), and we have recognized the

“well-established” “rule” that “an experienced narcotics agent” may testify as an

expert to help a jury understand “the significance of certain conduct or methods of

operation unique to the drug distribution business.” United States v. Butler, 102

F.3d 1191, 1199 (11th Cir. 1997) (internal quotations omitted). We also have

“affirmed the admission under Rule 702 of the expert testimony of a police officer

interpreting ‘drug codes and jargon.’” United States v. Novaton, 271 F.3d 968,

1008 (11th Cir. 2001) (quoting United States v. Brown, 872 F.2d 385, 392 (11th

Cir. 1989)).

      The district court did not abuse its discretion by permitting Special Agent

Cromer to testify as an expert witness. Cromer had been a DEA agent for several

years and had received training regarding the operation and structure of drug

trafficking organizations and how those organizations transport and distribute

drugs. Cromer had been involved in at least 50 drug investigations and the

majority of those involved Mexican drug trafficking organizations. Cromer also

had participated in numerous wiretap investigations and was familiar with the

coded language that some drug trafficking organizations use. Cromer clearly was

an “experienced narcotics agent,” and his testimony could have helped the jury



                                         17
understand the evidence. See id.; Fed. R. Evid. 702.

      Relevant evidence “may be excluded if its probative value is substantially

outweighed by the danger of unfair prejudice.” Fed R. Evid. 403. Special Agent

Cromer’s testimony was highly probative. Cromer’s testimony about drug

traffickers’ use of code words, for example, was probative because “drug dealers

often camouflage their discussions . . . [and] expert testimony explaining the

meanings of code words may ‘assist the trier of fact to understand the evidence or

to determine a fact in issue.’” United States v. Dukagjini, 326 F.3d 45, 52 (2d Cir.

2003) (quoting Fed. R. Evid. 702). Cromer’s testimony about how drug trafficking

organizations compartmentalize certain operations and roles was highly probative

because, as the government argues, “this is precisely the type of testimony . . . [that

could] help the jury understand how the conduct and evidence relating to the

individual participants might further the goals and purposes of the drug trafficking

organization.” The district court did not abuse its discretion in concluding that any

unfair prejudice Cromer’s testimony could have caused did not outweigh its high

probative value.

   2. The District Court Did Not Err Under the Sixth Amendment by Admitting
 Cromer’s Testimony About the Out-of-Court Statement of a Drug Trafficker Who
                     Testified at Trial to the Same Statement.

      Garcia and Nunez contend that, because Cromer explained that his opinion



                                          18
about the meaning of “shirts” was based on a statement made by Mojica, a

cooperating conspirator, part of Cromer’s testimony was hearsay admitted in

violation of the Sixth Amendment, as interpreted in Crawford. 541 U.S. 36, 124 S.

Ct. 1354. This argument fails because the Sixth Amendment, as interpreted in

Crawford, bars the admission of the out-of-court statements of declarants who do

not testify at trial: “the Framers would not have allowed admission of testimonial

statements of a witness who did not appear at trial.” Id. at 53-54, 124 S. Ct. at

1365 (emphasis added). Unlike the declarant in Crawford, id. at 40, 124 S. Ct. at

1357, Mojica testified at trial and he testified to the same statement Cromer had

described. Garcia and Nunez had ample opportunity to confront and cross-

examine Mojica, and Cromer’s testimony about Mojica’s statement was offered to

explain the basis of Cromer’s opinion as an expert.

 3. The District Court Did Not Abuse Its Discretion Under Rule 703 by Admitting
                  Cromer’s Testimony About Mojica’s Statement.

      Nunez objects that Cromer’s testimony was inadmissible hearsay, but a

district court enjoys the discretion to permit an expert witness to “disclose[] to the

jury” “[f]acts or data that are otherwise inadmissible” if “the court determines that

their probative value in assisting the jury to evaluate the expert’s opinion

substantially outweighs their prejudicial effect.” Fed. R. Evid. 703. It is

understandable that the district court might have wanted the jury to understand that


                                           19
Cromer had relied on the statements of Mojica: any problems with the credibility

of Mojica, whom the jury saw and heard testify, might have affected the decision

of the jury to credit or reject Cromer’s testimony.

      Nunez correctly reminds us that Rule 703 applies only when an expert

witness testifies about matters within the scope of his expertise. See Dukagjini,

326 F.3d at 58. We certainly agree that hearsay evidence admitted under Rule 703

“must be the type of evidence reasonably relied upon by experts in the particular

field in forming opinions or inferences on the subject,” United States v. Scrima,

819 F.2d 996, 1002 (11th Cir. 1987), but there is no abuse of discretion in

concluding that the debriefing of suspected drug traffickers is “the type of

evidence” that is “reasonably relied upon” by seasoned drug enforcement officers

“in forming opinions or inferences” about the use of coded language by drug

traffickers. This Court has recognized that a law enforcement officer testifying as

an expert witness may rely on information he received from other people if “such

sources of information were regularly relied upon” “by experts in his field.”

United States v. Brown, 299 F.3d 1252, 1257, 1258 (11th Cir. 2002), vacated, 538

U.S. 1010, 123 S. Ct. 1928 (2003), remanded to and reinstated by 342 F.3d 1245

(11th Cir. 2003), cert. denied, 543 U.S. 823, 125 S. Ct. 37 (2004). We have stated,

for example, that “Rule 703 encompasses hearsay statements in a context . . .



                                          20
where the government expert specifically testified that his opinion was based on

his experience and expertise, in conjunction with the information he received from

a DEA intelligence agent and Bermudan authorities, and that such sources of

information were regularly relied upon in valuating narcotics.” Id. at 1257. We

also have explained that “expert testimony by an ATF agent based partly on his

own analysis, but verified by consultation with an ATF technical specialist, was

properly admitted under Rule 703 where the agent testified that the consultation

was of the kind regularly relied upon by experts in his field.” Id. at 1257-58

(characterizing the holding in United States v. Floyd, 281 F.3d 1346, 1349-50

(11th Cir. 2002)).

      Nunez’s reliance on Dukagjini is misplaced. That court concluded that the

expert testimony “at times departed from the bounds of Rules 702 and 703 and

from reliable methodology” and the witness had “repeatedly deviated from his

expertise on drug jargon.” Id. at 58-59. Unlike Cromer, the expert in Dukagjini

“was relying on his conversations with non-testifying witnesses and co-defendants

in order to prove ‘the truth of the matter asserted’” rather than “translating drug

jargon, applying expert methodology, or relying on his general experience in law

enforcement.” Id. at 59. The court recognized that “an expert [is permitted] to rely

on hearsay evidence for the purposes of rendering an opinion based on his



                                          21
expertise,” id., but excluded the testimony in that case because “the expert was

repeating hearsay evidence without applying any expertise whatsoever,” id.

      In contrast with Dukagjini, the district court did not abuse its discretion in

concluding that Cromer had applied his expertise in relying on, among other

sources, his interview with Mojica to determine the meaning of coded language.

An experienced agent like Cromer, by virtue “of his professional knowledge and

ability, [was] competent to judge for himself the reliability of” statements made by

an admitted drug trafficker in post-arrest debriefings in forming an expert opinion

about the drug traffickers’ use of coded language. United States v. Williams, 447

F.2d 1285, 1290 (5th Cir. 1971). The district court did not abuse its discretion in

admitting that testimony.

   B. The District Court Did Not Abuse Its Discretion by Not Holding a Second
              Hearing on Whether to Disqualify Garcia’s Attorney.

      Garcia argues that the district court abused its discretion by not conducting a

second hearing on whether to disqualify Garcia’s attorney due to a conflict of

interest. Garcia does not argue that he received ineffective assistance of counsel.

Garcia argues that the district court should have intervened at trial when he

testified adversely to himself and favorably to Molina, although the district court

already had held a full hearing and Garcia had waived any actual, apparent, or

possible conflict. Garcia’s argument fails.


                                          22
      An attorney “may” be disqualified when an actual or even a potential

conflict of interest exists, United States v. Ross, 33 F.3d 1507, 1523 (11th Cir.

1994), but the defendant “may waive this conflict of interest and elect to have the

attorney continue representation, so long as that waiver is knowing, intelligent, and

voluntary,” id. at 1524; see McConico v. Alabama, 919 F.2d 1543, 1548 (11th Cir.

1990). “In order for a waiver of the right to conflict-free counsel to be knowing

and intelligent, the State must show that the defendant (1) was aware that a conflict

of interest existed; (2) realized the consequences to his defense that continuing

with counsel under the onus of a conflict could have; and (3) was aware of his right

to obtain other counsel.” Zuck v. Alabama, 588 F.2d 436, 440 (5th Cir. 1979).

Although the district court is not required to accept a defendant’s waiver, Wheat,

486 U.S. at 164, 108 S. Ct. at 1700, “a criminal defendant has a presumptive right

to counsel of choice and courts should hesitate to disqualify defense counsel,”

Ross, 33 F.3d at 1522-23 (citing Wheat, 486 U.S. at 164, 108 S. Ct. at 1700).

      Garcia knowingly, intelligently, and voluntarily waived objection to his

attorney’s conflict of interest. The magistrate judge held an extensive pretrial

hearing and confirmed that Garcia spoke English and was not under the influence

of drugs, alcohol, or medication. The magistrate judge explained how a conflict of

interest could arise in plea bargaining, exercising peremptory challenges to jurors,



                                          23
direct examination, and sentencing. The magistrate judge told Garcia the

government would pay for a lawyer to represent him. The magistrate judge told

Garcia the government even would pay for a lawyer to discuss with Garcia the

wisdom of proceeding without independent counsel. Garcia knew there was at

least a possible conflict, he knew how this conflict could harm his interests, and he

knew he had the right to an attorney at no cost to himself. Because Garcia

effectively waived any conflict following a thorough pretrial hearing, the district

court was not required to inquire at trial about Wright’s conflict of interest.

        C. Sufficient Evidence Supported Both Convictions for Conspiracy.

      Garcia and Nunez argue that the district court erroneously concluded that

sufficient evidence supported their convictions for conspiracy. “To convict a

defendant for conspiracy . . . , the evidence must show (1) that a conspiracy

existed, (2) that the defendant knew of it, and (3) that the defendant, with

knowledge, voluntarily joined it.” United States v. Perez-Tosta, 36 F.3d 1552,

1557 (11th Cir. 1994). “The very nature of conspiracy frequently requires that the

existence of an agreement be proved by inferences from the conduct of the alleged

participants or from circumstantial evidence of a scheme.” United States v. Ayala,

643 F.2d 244, 248 (5th Cir. Unit A 1981); see United States v. Spradlen, 662 F.2d

724, 727 (11th Cir. 1981). “A conspiracy conviction will be upheld . . . when the



                                           24
circumstances surrounding a person’s presence at the scene of conspiratorial

activity are so obvious that knowledge of its character can fairly be attributed to

him.” United States v. Figueroa, 720 F.2d 1239, 1246 (11th Cir. 1983). We apply

these standards to each verdict of guilt and conclude the evidence was sufficient.

       1. Sufficient Evidence Supported Garcia’s Conviction for Conspiracy.

      Garcia argues that his “mere presence” at the scene of a crime is insufficient

to convict him for conspiracy, but Garcia was not “merely” present in a house full

of drugs, drug money, drug traffickers, and at least one firearm. Most of the

physical evidence against Garcia was found in either his bedroom or bathroom,

Garcia admitted the drugs were his, and one of the digital scales had cocaine

residue. Garcia testified the drugs were merely for his personal use, but the jury

reasonably could have concluded that the drugs were for distribution because “a

defendant [who] chooses to testify . . . runs the risk that if disbelieved ‘the jury

might conclude the opposite of his testimony is true.’” United States v. Brown, 53

F.3d 312, 314 (11th Cir. 1995) (quoting Atkins v. Singletary, 965 F.2d 952, 961

n.7 (11th Cir. 1992)). Garcia lived with two conspirators and was related through

his common-law marriage to Cuevas, the ringleader of the conspiracy. It would

have been reasonable to conclude that Garcia’s drug activity was related to the

charged conspiracy.



                                           25
      The DEA agents also found nearly $300,000 in Garcia’s house, most of it in

his bedroom closet. “A person who owns or exercises dominion and control over a

. . . residence in which contraband is concealed may be deemed to be in

constructive possession of the contraband,” United States v. Vera, 701 F.2d 1349,

1357 (11th Cir. 1983), and “a defendant involved only in the money laundering

facet of the drug business could be considered a part of the conspiracy to distribute

those drugs,” United States v. High, 117 F.3d 464, 469 (11th Cir. 1997). The large

sum of money in Garcia’s room provided yet another basis for conviction.

Sufficient evidence supported Garcia’s conviction for conspiracy.

       2. Sufficient Evidence Supported Nunez’s Conviction for Conspiracy.

      Nunez argues the government failed to prove that he was the person

recorded on the phone calls, the phone calls involved illegal activity, the phone

calls referred to cocaine, or the phone calls were part of the conspiracy alleged in

the indictment. Each argument fails.

      First, a jury reasonably could have concluded that Nunez was the speaker in

the five phone calls. Self-identification and telephone subscriber information are

recognized means to establish the identity of persons speaking in recorded

conversations. See United States v. Green, 40 F.3d 1167, 1173 (11th Cir. 1994).

Three of the calls were to or from Nunez’s cell phone. In the fourth call, Cuevas



                                          26
asked for “Hector” and an unidentified female said that Hector had just returned

from Houston. Nunez’s first name is Hector and he is from Houston. In that same

call, Hector and Cuevas call each other “cuz.” Nunez and Cuevas are cousins.

      The fifth call was subject to comparison by the jury with the first four calls

because the government played all the calls at trial. The jury had the opportunity

to compare the voice, matter of discussion, manner of speech, and use of language

in the fifth call with these qualities and characteristics in the first four calls. We

view the evidence in the light most favorable to the government, see Miranda, 425

F.3d at 959, and a jury reasonably could have concluded that Nunez was the

speaker on these five phone calls.

      Second, a jury reasonably could have concluded that the recorded

conversations involved illegal activity. Nunez and Cuevas discuss “shirts,” a

“lady,” a “truck driver,” “McAllen,” and “Ruthie.” Special Agent Cromer testified

that “shirts” means “cocaine” and sometimes “methamphetamine,” “lady” means

“cocaine,” and he believed “Ruthie” referred to drugs. Cromer explained that

“McAllen” is a city in Texas that is an entry point for drugs smuggled into the

United States from Mexico and the word “trailer” refers to “a tractor trailer[,]

which is one of the common forms of how to transport drugs from McAllen, Texas,

to Atlanta.” A cooperating co-conspirator also testified that, in his conversations



                                            27
with Cuevas, “one shirt” meant “an ounce of cocaine.” The combination of

testimony about the meaning of coded language and conversations that “make little

facial sense at all but gain a great deal of meaning when viewed as coded

references to dealings in [drugs],” United States v. Atkins, 618 F.2d 366, 370 n.4

(5th Cir. 1980), was sufficient evidence to support a finding that Cuevas and

Nunez’s conversations were about drugs.

      Third, it was reasonable for the jury to conclude that the conversations were

about cocaine or methamphetamine. Mojica testified that “an ounce of cocaine is

one shirt.” Cromer testified that “shirts” meant “cocaine,” and sometimes

“methamphetamine.” Cromer also testified that “lady” meant “cocaine.” The

phone calls support the inference that Nunez was transporting something and it was

reasonable to conclude that that something was cocaine.

      Fourth, it was reasonable for a jury to conclude that the phone calls were

related to the charged conspiracy. Nunez contends that a “buyer-seller

relationship” is not sufficient to prove a conspiracy. We recognize that “two

parties . . . charged with agreeing to distribute drugs” might not be guilty of

conspiracy when the “evidence [demonstrates] that the parties understood their

transactions to do no more than support the buyer’s personal drug habit,” United

States v. Dekle, 165 F.3d 826, 830 (11th Cir. 1999), but there was ample evidence



                                          28
that Nunez was involved in much more than supplying whatever personal drug

habit Cuevas might have had. Nunez participated in the transportation of drugs in

cooperation with the ringleader of the charged conspiracy and used at least some of

the same coded language to discuss that conspiracy as had at least one other

conspirator. The jury reasonably could have concluded that Nunez was involved in

the conspiracy charged in the indictment.

D. Sufficient Evidence Supported Garcia’s Conviction for Possession of a Firearm
                   in Furtherance of a Drug Trafficking Crime.

      Garcia argues that the district court erroneously concluded that sufficient

evidence supported his conviction for possession of a firearm in furtherance of a

drug trafficking crime. A person violates federal law when “during and in relation

to any crime of violence or drug trafficking crime . . . [he] uses or carries a firearm,

or . . . , in furtherance of any such crime, possesses a firearm.” 18 U.S.C. §

924(c)(1)(A). To be “in furtherance” of a drug trafficking crime, there must be

“some nexus between the firearm and the drug selling operation.” United States v.

Timmons, 283 F.3d 1246, 1253 (11th Cir. 2002) (internal quotations omitted).

This argument fails.

       Because Garcia testified that the firearm belonged to him, the only question

is whether he possessed it “in furtherance” of a drug trafficking crime. Garcia

testified that he did not possess the firearm to protect the money, but “when a


                                           29
defendant chooses to testify, he runs the risk that if disbelieved ‘the jury might

conclude the opposite of his testimony is true.’” Brown, 53 F.3d at 314 (quoting

Atkins, 965 F.2d at 961 n.7). Because “a statement by a defendant, if disbelieved

by the jury, may be considered as substantive evidence of the defendant’s guilt,”

id., the jury was free not only to conclude that Garcia possessed the firearm to

protect the money, but also to rely upon that conclusion to convict Garcia. A

conclusion of guilt based on Garcia’s testimony would have been supported by

evidence that Garcia’s firearm was in the open drawer of the nightstand in the

bedroom, the bedroom and adjoining bathroom contained drugs, a bedroom closet

contained a large amount of money that Garcia openly admitted he suspected to be

drug proceeds, and Garcia was concerned someone might try to take the money.

Sufficient evidence supported Garcia’s conviction under section 924.

                                IV. CONCLUSION

      We affirm the convictions of Garcia and Nunez.

      AFFIRMED.
