Jоhn Turner (“Turner”) appeals his conviction for violating 21 U.S.C. § 846, participating in a conspiracy to distribute over 100 kilograms of marijuana, and a separate count under 21 U.S.C. § 846, for a separate conspiracy to distribute over five kilograms of cocaine. On appeal, Turner argues that the district court erred by: (1) ruling that there was sufficient evidence to support a finding that Turner conspired to distribute more than five kilograms of cocaine; (2) applying a 2-level increase to Turner’s offense level based on the five kilograms of cocaine allegedly involved in the conspiracy; and (3) applying a sentencing enhancement for Turner’s role as an “organizer, leader, manager, or supervisor” under U.S.S.G. § 3B1.1. We disagree and affirm.
I. BACKGROUND
Over a two-year period, various law enforcement agencies jointly investigated an alleged drug conspiracy located in Arlington, Texas. The conspiracy began in January 1997 and сontinued until November 8, 2000. Two businesses were tied to the ■drug conspiracy as legitimate fronts for the drug distributors. The first business, “That Sounds Good,” was a car stereo shop owned by one of the alleged co-conspirators, Nathan Henderson (“Henderson”). Turner owned the second business, “Platinum Sounds,” a CD store located adjacent to Henderson’s stereo shop in the same strip mall. Henderson, Turner, and a third alleged co-conspirator, Julius Robinson (“Robinson”), organized a schеme to *719 sell and distribute marijuana to Turner’s friend in Missouri, Alex Jones (“Jones”).
Henderson and Turner typically shipped and received packages containing controlled substances from their business location in the strip mall. They received packages containing drug money at the same location, and on some occasions, at Turner’s home address. Leteisha Barnett (“Barnett”), an employee of Platinum Sounds and That Sounds Good, signed for the packages оn behalf of Henderson and Turner when they came to the store. In exchange for lending Barnett money for her apartment, Henderson enlisted Barnett to store marijuana in her apartment. Turner, Henderson, and Robinson would often go to Barnett’s apartment to package and store marijuana, and Henderson eventually had her lease a storage unit for the marijuana. On at least a few occasions, Turner had Barnett deliver packages of marijuana to the UPS facility at the Dallas-Fort Worth Airport.
Alleged co-conspirator, Victor Jiminez (“Jiminez”), was one of the major suppliers of marijuana to Henderson and Robinson, and was the cocaine supplier to Robinson. Jiminez sold Turner and Henderson a total of nearly 2,000 pounds of marijuana. Jimi-nez recalled selling cocaine to Robinson three or four times, for a total quantity of approximately four kilograms. According to Jiminez, Robinson also asked to purchase cocaine from him on three or four other occasions, but he was unable to satisfy Robinson’s request. On one of these occasions, Robinson requested one-half of a kilogram of cocaine, but Jiminez refused because he normally only dealt in kilogram quantities. During these transactions, the alleged co-conspirators used certain code words. For instance, to refer to one kilogram of cocaine, they would use the terms, “thе other” or “a T-shirt”.
In June 2000, a series of phone calls took place between Turner and Robinson and between Robinson and Jiminez. The Government intercepted and recorded the calls. The DEA case agents who listened to all of the intercepted calls found that Turner’s conversation with Robinson about cocaine and Turner’s conversation with Henderson about marijuana demonstrated his familiarity with the other’s drug-dealing terminology and that it appearеd to be more than just an isolated transaction. 1 *720 As a result of these conversations, law enforcement obtained a search warrant for Turner’s residence. When executed, the search netted guns, cell phones, and $8,500 in cash, but no illegal substances.
Turner was indicted with thirty-six other people. The indictment ultimately charged Turner, in count 1, with participating in a conspiracy to distribute over 100 kilograms of marijuana in violation of 21 U.S.C. § 846, 2 and in count 2, with a separate conspiracy to distribute over five kilograms of cocaine in violation of 21 U.S.C. § 846. 3
Turner waived his right to trial by jury. At trial, several co-defendants testified that Turner was involved in selling marijuana. While none of the co-defendants testified that they had personal knowledge of Turner selling cocaine, Henderson revealed that he heard from Robinson (who did not testify at Turner’s trial) that Turner was involved in selling cocaine. Another individual testified that Turner would refer persons in search of cоcaine to Robinson.
The district court convicted Turner on both counts. In Turner’s Presentence Report (“PSR”), the Probation Office made the following findings: (1) Turner was responsible for approximately 2,600 kilograms of marijuana, resulting in a base offense level of 32; 4 and (2) Turner’s management of Leteisha Barnett warranted a two-level increase for his role as an “organizer, leader, manager or supervisor.” 5 Turner’s total offense level of 34 combined with his Category IV criminal history score resulted in a guideline imprisonment range of 210 to 262 months. The court sentenced Turner to: (1) 262 months in prison on counts 1 and 2 (to run concurrently); (2) five years of supervised release on counts 1 and 2; and (3) a special assessment of $200. He timely filed a notice of appeal.
II. ANALYSIS
A Sufficiency of the Evidence to Support the Cocaine Conspiracy Conviction
1. Standard of Review
This Court’s standard of review in “evaluating the sufficiency of the evidence supporting a conviction after a bench trial is whether the finding of guilt is supported by substantial evidence, i.e., evidence sufficient to justify the trial judge, as the trier of fact, in concluding beyond reasonable doubt that the defendant is guilty.”
United States v. Mathes,
2. Discussion
On appeal, Turner asserts that the Government did not provide an adequate factual basis to support his conviction of conspiracy to distribute more than five kilograms of cocaine. According to Turner, the evidence does not demonstrate: (1) an agreement between Turner and Robinson existеd to distribute more than five kilograms of cocaine; (2) that Turner knew of any such agreement pertaining to more than five kilograms of cocaine; or (3) that Turner voluntarily participated in the distribution of more than five kilograms of cocaine. Conversely, the Government contends that given its burden of proof under
Apprendi v. New Jersey,
To prove that a defendant is guilty of conspiring to distribute illegal drugs under 21 U.S.C. § 846, the Government must prove beyond a reasonable doubt: “(1) the existence of an agreement between two or more persons to violate narcotics laws, (2) knowledge of the conspiracy and intent to join it, and (3) voluntary participation in the conspiracy.”
United States v. Peters,
In this case, because the indictment alleges Turner’s involvement in a conspiracy to distribute a quantity greater than five kilograms of cocaine, thereby triggering punishment within the statutory range of 21 U.S.C. § 841(b)(1)(A), a fourth element applies under
Apprendi. United States v.
*722
DeLeon,
Turner maintains that the Government failed to carry its burden of proof with regard to the fourth element by failing to show that more than five kilograms of cocaine were attributable to Turner’s participation in the conspiracy. The Government submits that this case raises an issue of first impression in this circuit: whether in drug conspiracies post-Apprendi, the drug quantity element must be proven as to each alleged co-conspirator or whether it merely must be proven to the conspiracy as a whole. This issue is dispositive because, while there is legally sufficient evidence linking the entire conspiracy to more than five kilograms of cocaine, evidence linking Turner directly to that amount is non-existent.
a. The Government’s Burden of Proof under Apprendi
The First Circuit addressed the precise issue of whether the Government has to prove that the requisite drug quantity is attributable to an individual co-conspirator in
Derman v. United States,
Harmonizing
Apprendi
with the Supreme Court’s earlier decision in
Edwards v. United States,
[I]n a drug conspiracy case, the jury should determine the existence vel non of the conspiracy as well as any facts about the conspiracy that will increase the possible penalty for the crime of conviction beyond the default statutory maximum; and the judge should determine, at sentencing, the particulars regarding the involvement of each participant in the conspiracy. This means that once the jury has determined that the conspiracy involved a type and quantity of drugs sufficient to justify a sentence above the default statutory maximum and has found a particular defendant guilty of participation in the conspiracy, the judge lawfully may determine the drug quantity attributable to that defendant and sentence him accordingly.... The rule, then, is that the government need only allege and prove to the jury the bare facts necessary to increase the statutory sentencing maximum for the conspiracy as a whole.
Derman,
Applying the Derman rule to this case, the Government’s burden was to prove the existence of a conspiracy, Turner’s involvement in it, and the requisite drug quantity (here, more than five kilograms) involved in the conspiracy beyond a *723 reasonable doubt. Once the Government makes this showing, at sentencing, it need only prove the drug quantity attributable to Turner by a prepondеrance of the evidence (provided that his sentence falls within the statutory maximum made applicable by the fact finder’s conspiracy-wide drug quantity determination). 7
b. Sufficiency of the Evidence .
Realizing the exact nature of the Government’s burdens, substantial direct and circumstantial evidence exists to support the district court’s finding of a drug conspiracy under § 846.
See generally, United States v. Greenwood,
First, the Government provided circumstantial evidence of an agreement between two or more persons to violate federal narcotics laws. As “[t]he gravamen of a drug conspiracy offense is the agreement to violate a drug law[,] [a]n express, explicit agreement is not required; a tacit agreement will suffice.” Id. The Government’s proffered evidence showed that Jiminez sold distribution quantities of cocaine to Robinson and on other occasions, Robinson unsuccessfully requested additional quantities of cocaine from Jiminez. This evidence is sufficient to demonstrate at least a tacit agreement to violate federal narcotics laws.
The taped telephone conversations provide sufficient evidence to satisfy the final two elements of a drug conspiracy. The Robinson-Turner and Robinson-Jiminez conversations suggest that Turner made a request for cocainе from Robinson (knowing that Robinson could respond to his request); that Turner knew that Robinson received the cocaine from a third party; and that Turner was familiar with the terms of transactions under the Robinson-Jiminez agreement. Turner, Robinson, and Jiminez communicated over the phone in such a manner that it circumstantially demonstrates knowledge of the agreement.
Turner’s voluntary participation in the agreement is also evident. Given that “[c]oncert of action may indicаte ... voluntary participation” in a drug conspiracy,
United States v. Quiroz-Hernandez,
The only debatable issue regarding the district court’s finding of guilt is whether there is substantial evidence to establish that the drug conspiracy involved more than five kilograms of cocaine. The Gov *724 ernment only provided direct evidence оf the involvement of 4.5 kilograms of cocaine. The conspiracy’s tie with Robinson is critical here. The Government asserts that Jiminez and Robinson’s conversations about transactions that did not materialize create the inference that the conspiracy involved at least five kilograms. We agree. Because Jiminez dealt in one-kilogram quantities only, any additional request by Robinson of Jiminez would have pushed the total drug quantity involved in the conspiracy ovеr five kilograms. Viewing the evidence in the fight most favorable to the Government, which this Court must do, the inference that more than five kilograms were involved is reasonable. Therefore, the evidence was sufficient to show Turner’s involvement in a conspiracy in which more than five kilograms of cocaine were involved.
B. Turner’s Base Offense Level and Sentencing Enhancements
1. Standard of Review
This Court reviews for clear error a district court’s factual determination regarding, for sentencing purposes, the quantity of drugs used to establish a base оffense level,
United States v. Johnston,
2. The 2-Point Increase to Turner’s Base Offense Level
Turner contends that, based on the trial testimony and the information on which the PSR relies, the district court erred in imposing a 2-point increase to his base offense level for his alleged involvement with five kilograms of cocaine. He maintains that, under U.S.S.G. § 1B1.3, the distribution of five kilograms of cocaine, which the PSR counted as 1,000 kilograms of marijuana, was outside the scope of relevant conduct attributable to him. At most, Turner contends, only one-half of a kilogram of cocaine could actually be attributed to him. Turner does not argue, however, that the district court erred in attributing 1,600 kilograms of marijuana to him. The Government concedes that it was error to hold Turner responsible for five kilograms of cocaine. Notwithstanding this error, the Government contends that the sentence should be affirmed because the error had no effect on his base offense level, and therefore was harmless.
When determining the base offense level of a co-conspirator, the Sentencing Guidelines’ “reasonable foreseeability” requirement necessitates a consideration of when the сo-conspirator joined the conspiracy, what drug quantities were within the scope of the conspiratorial agreement, and of those drug quantities, the quantities that were reasonably foreseeable, prospectively only, by the defendant.
United States v. Carreon,
As the Government concedes, because of the scant evidence indicating that Turner was involved with five kilograms of cocaine or reasonably foresaw that the ob- *725 jeet of the conspiracy was to distribute that particular quantity of cocaine, the district court clearly erred in attributing five kilograms of cocaine to Turner.
The critical question, then, is whether the district court’s attribution of the cocaine quantity to Turner warrants a reversal of the court’s application of a base offense level of 32. Significantly, the court also found that 1,600 kilograms of marijuana could be directly attributed to Turner. Such a finding is not clearly erroneous. Consequently, Turner suffered no prejudice as a result of the district court’s erroneous factual finding with regard to the cocaine; because even if the five kilograms of cocaine (equivalent to 1,000 kilograms of marijuana) were subtracted from the overall drug amount, a base offense level of 32, which covers a range from 1,000 to 3,000 kilograms of marijuana, would still apply. See U.S.S.G. § 2Dl.l(c)(4) (2001). Because the district court’s error was harmless, we affirm its application of a base offense level of 32.
3. Sentencing Enhancement for. Turner’s Role in the Conspiracy
Finally, Turner contends that the district court erred by increasing Turner’s base offense level by two points for his role as an “organizer, leader, manager, or supervisor” in the marijuana conspiracy under U.S.S.G. § 3Bl.l(c). Turner argues that he was not a manager or a supervisor because: (1) Barnett’s participation in the conspiracy originated with Henderson’s request-not Turner’s; and (2) Turner did not “profit more” than anyone else from Barnett’s participation in the conspiracy. The Government maintains that the district court did not clearly err in finding that Turner had a managerial or supervisory role in the conspiracy because the evidence showed that: (1) Turner directed the activities of Barnett in sending and accepting packages for him concerning his marijuana distribution; (2) Barnett stored marijuana for Turner; and (3) Turner paid Barnett for these services.
Based on the evidence, the district court did not clearly err in finding that Turner could be characterized as having a managerial or supervisory role in the marijuana conspiracy under § 3Bl.l(c). When the evidence demonstrates that a defendant directed another in his drug trafficking activities, as Turner directed Barnett in numerоus ways, sentence enhancement under § 3Bl.l(c) is appropriate.
United States v. Posada-Rios,
III. CONCLUSION
For the foregoing reasons, we conclude that the district court did not err in finding that there was sufficient evidence to show that Turner was involved in a conspiracy to distribute more than five kilograms of cocaine, and that Turner was a manager or supervisor in the marijuana conspiracy under § 3Bl.l(c). While the district court clеarly erred in attributing five kilograms of cocaine to Turner for purposes of sentencing, the error was harmless. We therefore affirm.
Notes
. To support this assertion, the Government offered the following series of calls:
First Call: 5:03 p.m.
Turner: I said, them niggas [unintelligible] my other shit?
Robinson: Uh, shit. Yeah, I think so, man. Uh, uh, but you gotta have cash in hand though, before I even call 'em.
Turner: [Unintelligible] like a half, and I need to check the uh, numbers on it, man. Robinson: Okay, uh, let me, let me call him and see. Alright?
Turner: Aright.
Second Call: 6:16 p.m.
Robinson: I got ... I got a dude down here man, one of my homies down here man, want a half a t-shirt.
Jiminez: Uh, but my homeboy, he’s out of town right now.
Robinson: Yeah?
Jiminez: Yeah, but uh ... I could probably check with my cousin on that.
Robinson: Yeah, check on that for me. So, it’s for sure this time, it's cash at hand, I just want to know what the ticket is.
Jiminez: Okay.
Robinson: You don’t know what the ticket is? Jiminez: No, I sure don’t, I’ll give him a call right now.
Robinson: Okay.
Third Call: 1:22 p.m.
Robinson: Hello?
Turner: So what he say, man?
Robinson: He's supposed to be giving me a call back, man. He checking on the prices. Fourth Call: 7:31 p.m.
Robinson: What’s up, Vic?
Jiminez: Nothin' much, dawg. They got some but it don’t all come back, it don't drop. Robinson: It don't?
Jiminez: Naw, it's good for the other.
*720 Robinson: Oh, okay. Well, thanks for telling me, man.
Fifth Call: 7:35 p.m.
Turner: Yeah.
Robinson: Hey, has ... he ... he called me back, man.
Turner: Okay.
Robinson: He say ... he said it he ain't coming back, man.
Turner: Oh, okay.
Robinson: It's good for tootin', and that’s it. You know what I’m saying? So ... Turner: Huh?
Robinson: I say ... he said it's just good for tootin'. It ... it ain't good for cooking[J Turner: Yeah.
. The penalty for this offense is found at 21 U.S.C. § 841(b)(1)(B).
. The penalty for this offense is found at 21 U.S.C. § 841(b)(1)(A).
. See U.S.S.G. § 2D1.1(c)(4). The PSR attributed 1,600 kilograms of marijuana and 5 kilograms of cocaine to Turner. The PSR converted the 5 kilograms of cocaine to 1,000 kilograms of marijuana, resulting in a total of 2,600 kilograms of marijuana.
. See U.S.S.G. § 3B1.1(c).
. To support its contention, the Government points to evidence that they recorded Turner seeking one-half оf a kilogram of cocaine from Robinson, who, in turn, sought to buy it from Jiminez. Jiminez, in turn, testified that he sold Robinson at least four kilograms and discussed the sales of many more possible kilograms with him.
. It is also instructive that, even after
Appren-di,
this Court has not required the Government to individually attribute the requisite drug quantity to each co-conspirator, and has affirmed drug conspiracy convictions based on the Government attributing the requisite drug quantity to the drug conspiracy as a whole.
E.g., United States v. Baptiste,
. In its brief, the Government relies on the "slight evidence” rule in arguing thаt Turner was a voluntary participant in the drug conspiracy. This Court overruled the "slight evidence” rule in
United States v. Malatesta,
nevertheless, this test persistently reappears.
