This appeal follows a jury conviction of defendant-appellant Cesar Acosta-Gallardo on one count of conspiracy to traffic in methamphetamine, in violation of Title 21, United States Code, Sections 846, 841(a)(1), and 841(b)(1)(A) (collectively, Count One), and on one count of using a telephone to facilitate a felony drug offense, in violation of Title 21, United States Code Section 843(b) (Count Eleven). Acosta-Gallardo appeals his conviction, alleging a variance, a Brady violation, improper venue, and that insufficient evidence was presented to sustain his Count One conviction for alleged trafficking in methamphetamine. Exercising jurisdiction of this appeal pursuant to Title 28, United States Code, Section 1291, we affirm.
I. Facts
Drug Distribution Activity
Much of the evidence against AcostaGallardo was introduced through the testimony of co-defendant Alvaro AlvaradoSanabria (“Alvarado”). Alvarado was arrested on October 13, 2009, and as part of his plea agreement that followed, he agreed to provide information on people with whom he dealt in drugs.
At the time of his arrest, Alvarado had been involved in distributing methamphetamine for roughly three years. Alvarado testified that he was first exposed to dealing in methamphetamine through a man named Alfredo Garcia, who imported drugs from Mexico. Alvarado and Garcia first became acquainted in late 2006 or early 2007 when Garcia came to Alvarado’s *1113 place of employment, looking for work. Alvarado helped Garcia find employment and also let him a room. As they beсame better acquainted, Alvarado agreed to lend Garcia money at a favorable interest rate. After loaning Garcia money three or four times, Alvarado found out that Garcia was using the money to purchase methamphetamine for distribution. R., Vol. 3 at 144-45. Alvarado testified that in the beginning, he was just loaning money to Garcia as an investment. Id. at 145^6.
Garcia returned to Mexico several times a year and Alvarado took over the methamphetamine distribution operation. Alvarado testified that he and Garcia were like “partners.” He became acquainted with Garcia’s driver, who transported the methamphetamine to Utah. Alvarado also met Garcia’s customers. Alvarado testified that he and Garcia had three sources for obtaining methаmphetamine: (1) a source called “Police,” (2) Juvenal Garcia (a co-defendant), and (3) the defendant, Acosta-Gallardo.
In the beginning, Alvarado had only one buyer, Brahnson Arnell. Arnell lived in Lyman, Wyoming. Alvarado testified that his only reason for communicating with Arnell was to sell him methamphetamine. Alvarado sold methamphetamine to Arnell for approximately three years. Arnell introduced Alvarado to some of his customers in Wyoming so that Alvarado could deal directly with them. These customers included Alvarado’s co-defendants, Robert Landry, Charles Thunehorst, Charles Jerabek, Jason Freeman, and Matthew Owens. Alvarado estimated that between 2007 and 2009, he sold two to four pounds of methamphetamine to Landry, five to eight pounds to Thunehorst, and roughly three to four pounds to Owеns. In turn, some of these customers sold methamphetamine to their own customers. For example, Landry sold methamphetamine he received from Alvarado to Freeman, George Burkett, Tommy Burkett, Kevin Watson, and others.
Alvarado testified he would deliver methamphetamine to his Wyoming customers at one of several pre-arranged meeting places off of Interstate 80 between Salt Lake City, Utah, and Rock Springs, Wyoming. R., Vol. 5 Ex. 103; R., Vol. 3 at 336-40. Each location was assigned a code number, and the delivery location would be communicated by referencing the location’s code number.
Alvarado and Defendant Cesar AcostaGallardo
During one of his stays in Utah, Garcia told Alvarado about Acosta-Gallardo, who was from his home town in Mexico and needed a place to live. Alvarado owned several cоndos and apartments at the time and let one of them to Acosta-Gallardo. Garcia informed Alvarado that Acosta-Gallardo “was someone really important in the drugs,” “that [Acosta-Gallardo] was able to get like big quantities [of drugs],” and that “[Acosta-Gallardo] was able to be a resource.” R., Vol. 3 at 152. Prior to this, Alvarado’s main source of methamphetamine had been Juvenal Garcia. Alvarado testified, however, that Juvenal Garcia was unable to get the methamphetamine that Alvarado needed. Id. at 153-54. As a result, in the summer of 2007, Alvarado and Alfredo Garcia began acquiring their methamphetamine from Acosta-Gallardo.
Alvarado and Garcia would obtain pounds of methamphetamine from AcostaGallardo and resell it to their customers in smаller amounts. Alvarado testified that he purchased methamphetamine from Acosta-Gallardo once every one to two months. Id. at 163. Most of the time, Defendant Acosta-Gallardo would advance Alvarado the methamphetamine on credit and Alvarado would pay him for it later. Id. at 164.
*1114 Alvarado testified that after he ordered methamphetamine from Acosta-Gallardo, Acosta-Gallardo would contact him a few days later and would then either deliver the methamphetamine himself or send his driver. Alvarado would sometimes help retrieve the methamphetamine from the delivery vehicle, where it was usually concealed in the engine compartment between the windshield and the engine. Alvarado testified that in 2007 and 2008, when he lived in Park City, Utah, his apartment cоmplex had an underground garage where he and Acosta-Gallardo could retrieve the drugs from the vehicle without being seen from the outside.
Alvarado stored the methamphetamine he received from Acosta-Gallardo in a brown suitcase that was kept in a closet in his (Alvarado’s) residence. Id. at 176-78. Alvarado stored different purchases of methamphetamine in separate containers. Id. at 178-80. At trial, Alvarado was shown a photograph of the contents of the suitcase seized from his apartment. R., Vol. 5, Ex. 115. In the photograph, Alvarado identified three different packages of methamphetamine that he had received from Acosta-Gallardo. R., Vol. 3 at 181-82. Alvarado testified that Acosta-Gallardo had seen the suitcase many times, and that Acosta-Gallardo was aware that Alvarado kept methamphetamine in that suitcase. Id. at 184-85.
Phone Exchanges Between Alvarado and Acosta-Gallarduo
Alvarado testified that he kept two cell phones. One phone was for personal use. The other phone was his “business phone,” R. Vol. 3 at 188, which he changed every four to six weeks to avoid tracking by law enforcement. Id. at 185. Acosta-Gallardo’s contact information was kept in Alvarado’s business phone. Alvarado testified that between 2007 and 2009, he changed phones approximately fifteen to twenty times. He purchased his business phones from Wal-Mart. The phones were never registered in Alvarado’s name. In order to be assigned a phone number, Alvarado would provide a zip code from Idaho, Colorado, or Wyoming so that his assigned phone number would correspond to that zip code. Alvarado never provided the zip code of the city where he actually lived.
At trial, the government introduced the transcript of a text message that Alvarado received from Acosta-Gallardo on September 11, 2009. R., Vol. 3 at 192-93; R., Vol. 5 Ex. 123. The message, translated into English from Spanish, stated, “Dude, there is a [Female] friend that is 18 years old if you want to meet her.” R., Vol. 5, Ex. 123. Alvarado testified that “amiga,” or “female [friend],” meant that Acosta-Gallardo had one pound of methamphetamine. R., Vol. 3 at 192. The reference to “18” meant “18,000.” Id. Thus, Alvarado testified that Acosta-Gallardo’s message communicated the idea that he had “a pound of meth for $18,000, and he want[ed] to know if I wanna, I wanna [sic] buy that from him.” Id.
Transcripts of several phone conversatiоns that took place on September 12, 2009 were next introduced at trial. R., Vol. 5 at Exs. 124, 125, 126. The transcripts reflected both the conversations, all of which took place in Spanish, and their English translations. R., Vol. 3 at 189. The first phone conversation is dated September 12, 2009, and time-stamped “17:34:47 MDT-17:36:02 MDT.” R., Vol. 5 Ex. 124. Alvarado testified that in this conversation, he and Acosta-Gallardo were coordinating the delivery of drugs mentioned in the September 11, 2009 text message. Alvarado testified that in this phone conversation, he was communicating to Acosta-Gallardo that he (Alvarado) was not yet at home. R., Vol. 3 at 194-95.
The second phone conversation is also dated September 12, 2009, and is time *1115 stamped “19:39:22 NDT-19:39:58 MDT.” R., Vol. 5 Ex. 125. During this phone conversation, Avarado contacted AcostaGallardo to tell him that he had just arrived home. R., Vol. 3 at 196. AcostaGallardo’s response, as explained by Avarado, indicated that Acosta-Gallardo was on his way to meet Avarado. Id.
The third phone call was similarly dated September 12, 2009, and time-stamped “20:07:58 MDT-20:08:36 MDT.” R., Vol. 5 Ex. 126. Avarado explained that this phone conversation took place a few minutes before Acosta-Gallardo arrived at Avarado’s home. R., Vol. 3 at 197-98. Avarado explained that Acosta-Gallardo asked where to park, and Avarado directed Acosta-Gallardo to the parking lot behind his apartment. Id. at 198.
Avarado testified that, after these three phone conversations, Acosta-Gallardo delivered eight ounces of methamphetamine to him. Id. The drugs were advanced to him on credit. Id. Avarado stored the drugs in one of the containers in his suitcаse and eventually sold it to his customers, most of whom were in Wyoming. Id. at 198-99.
The transcript of an additional phone conversation between Acosta-Gallardo and Avarado, dated September 16, 2009, and time-stamped “11:22:26 MDT-11:29:20 MDT,” was introduced into evidence by the government. R., Vol. 5 at Ex. 127. Avarado initiated this phone call to Acosta-Gallardo and told him, “it is pretty, I’ve been told that it truly rocks.” R., Vol. 3 at 199-200; R., Vol. 5 Ex. 127 at page 2, line 8. Avarado testified that his comment meant that the quality of the drugs he obtained from Acosta-Gallardo on September 12, 2009 was “quite good.” R., Vol. 3 at 199-200. Acosta-Gallardo responded (in Spanish), “I told you, you were going to like it.” Id. at 200-201; R., Vol. 5 Ex. 127 at page 2, line 11. Avarado then communicated to Acosta-Gallardo, in code, that it would take him a few days to collect the money owеd for the September 12, 2009 drug delivery. R., Vol. 3 at 202; R., Vol. 5 Ex. 127 at page 2, line 18. Avarado testified that Aeosta-Gallardo’s response indicated that he was agreeable to that arrangement. Id. (discussing R., Vol. 5 at page 2, line 19).
Avarado testified that a week after the September 12, 2009 drug transaction, he paid Acosta-Gallardo $4,500, half of the amount due for the eight ounces of methamphetamine delivered. Id. at 224-25. Then, on October 12, 2009, a day before Avarado was arrested, Avarado paid Acosta-Gallardo the remaining $4,500 due for the September 12, 2009 delivery. Id.
The Investigation
Federal agents made two controlled purchases from Avarado. On September 24, 2009, an undercover agent purchased four ounces of methamphetamine for $6,000 using marked bills. Of the $6,000 paid, $1,200 in marked funds was later recovered from Aeosta-Gallаrdo’s vehicle. R., Vol. 3 at 96-99. On October 13, 2009, an undercover agent made the second controlled purchase of eight ounces of methamphetamine for $11,000. Id. at 95-96. Immediately following this purchase, Avarado was arrested.
A DEA agent testified that an estimated forty pounds of methamphetamine was at issue over the course of the investigation. Id. at 534. Using the lowest purity level found in the drugs seized from Avarado, which was a 7.2% purity of methamphetamine, forty pounds of methamphetamine would be equivalent to over 50 grams of “actual” methamphetamine. Id. at 534-35. The DEA agent estimated that over ten pounds of methamphetamine were attributable to Acosta-Gallardo. Id.
*1116 II. Analysis
Acosta-Gallardo appeals his conviction on four grounds. First, he argues that there was a varianсe between his indictment and the facts proven at trial. Second, he argues that the government committed a violation of his rights as recognized in
Brady v. Maryland,
1. Whether a variance in the evidence established facts different from those alleged in Count Eleven
Count Eleven charged Acosta-Gallardo with the following:
On or about September 12, 2009, at approximately 5:34 p.m., 7:39 p.m., and 8:07 p.m. in the District of Wyoming, the Defendants, Alvaro Alvarado-Sanabria and Cesar Acosta-Gallardo, did knowingly, intentionally, and unlawfully use a communication facility, to wit: a telephone, in causing or facilitating the commission of acts constituting a felony under the federal controlled substance act, to wit: conspiracy to possess with the intent to distribute, and to distribute, methamphetamine, in violation of 21 U.S.C. § 846, as more fully alleged in Count One of this Indictment. In [sic] violation of 21 U.S.C. § 843(b).
R., Vol. 1 at 28. Acosta-Gallardo argues that the evidence used in the government’s case to demonstrate that Acosta-Gallardo used a communication facility in furtherance of a conspiracy actually involved phone calls of October 12, 2009, not September 12, 2009, as charged in the indictment. Acosta-Gallardo argues that this amounted to a variance, and that no reasonable jury could have found Acosta-Gallardo guilty of Count Eleven.
“A variance arises when the evidence adduced at trial establishes facts different from those alleged in an indictment.”
United States v. Ailsworth,
Because we are convinced that no variance occurred, we need not reach the issue of Acosta-Gallardo’s substantial rights. As recounted above, the government introduced the transcripts of three phone conversations between Alvarado and Acosta-Gallardo that took place on September 12, 2009. At trial, Alvarado explained the context of those phone calls and how they facilitated Acosta-Gallardo’s delivering eight ounces of methamphetamine to him on September 12, 2009. Alvarado further testified that he sold that methamphetamine to his customers, at least some of whom were in Wyoming.
*1117 Thus, the evidence introduced at trial did not establish facts different from those alleged in the indictment. Accordingly, there was no variance.
2.
Whether the Government Failed to Present Knowledge of Potentially Exculpatory Evidence Prior to Trial in Violation of Brady v. Maryland,
Acosta-Gallardo next argues that the government committed a
Brady
violation because it delayed disclosing Alvarado’s proffer that Acosta-Gallardo handled the glass methamphetamine storage jars kept in the brown suitcase seized from Alvarado’s apartment.
1
Aplt’s Br. at 13-14; Oral Argument 2:18 to 3:43. To succeed on his
Brady
claim, Acosta-Gallardo must demonstrate that the prosecution suppressed evidence, that the evidence was favorable to him, and that the evidence was material.
United States v. Smith,
The glass jars аt issue were seized from Alvarado’s apartment on October 13, 2009. R., Vol. 3 at 505-06. The government represented that it learned, at most one week prior to trial, that Alvarado would testify that Acosta-Gallardo handled the glass jars and communicated that to Acosta-Gallardo at most four to five days later. Oral Argument 12:26-13:25. A DEA agent testified at trial that the glass jars were not fingerprinted because the agent found out just before trial that AcostaGallardo may have handled them. R., Vol. 3 at 610-11. Acosta-Gallardo indicates that he learned of Alvarado’s proffer the day before trial, and had he known about it sooner, he would have requested a continuance and had the jars fingerprinted because the results of the fingerprint analysis “would have been exculpatory to both innocence or guilt.” Aplt’s Br. 13.
Acosta-Gallardo’s arguments, however, fall short of establishing a Brady violation. Assuming arguendo that the government did delay disclosing Alvarado’s testimony to Acosta-Gallardo, and that Acosta-Gallardo would have had the jars fingerprinted, no one knows whether the results would have been favorable to Acosta-Gallardo. This fails to satisfy the second prong of Brady.
Additionally, Acosta-Gallardo does not establish a reasonable probability that the outcome of the proceedings would have been different if the jars had been fingerprinted. If Acosta-Gallardo’s fingerprints had been on the jars, Alvarado’s testimony would have been corroborated. On the other hand, if Acosta-Gallardo’s fingerprints were not on the jars, that could have meant anything “from the failure of the fingerрrints to be preserved, Mr. Alvarado-Sanabria’s innocent misrecollection about whether [Acosta-Gallardo] handled the item, to the fingerprints never being preserved in any readable format in the first place.” R., Vol. 1 at 355 (Order Denying Motion for Acquittal July 23, 2010 at 6). As the district court phrased it, “absence of evidence is not evidence of ab *1118 sence.” Id. Thus, Acosta-Gallardo has failed to establish any Brady violation.
3. Whether Venue was Proper for Counts One and Eleven
Acosta-Gallardo next argues that venue for Counts One and Eleven was improper in the District of Wyoming. Moreover, Acosta-Gallardo argues that the district court’s failure to instruct the jury on venue constituted structural error and is per se reversible. Aplt’s Br. at 14.
Whether A Reasonable Jury Could Have Found Venue by a Preponderance of the Evidence
The Constitution contains two provisions on venue in criminal cases.
United States v. Medina-Ramos,
“Although venue is a right of constitutional dimension, and has been characterized as ‘an element of every crime,’ ... [it] need not be proved beyond a reasonable doubt.”
United States v. Miller,
Count One
Count One charges Acosta-Gallardo and his co-defendants with “knowingly, intentionally, and unlawfully combining], conspirfing], confederating] and agree[ ]ing], to possess with intent to distribute, and to distribute, 50 grams or more of methamphetamine (actual), a Schedule II controlled substance.” R., Vol. 1 at 24. Venue for a conspiracy is proper in any jurisdiction where an overt act in furtherаnce of a conspiracy was committed by any of the conspirators, even if the defendant has “neither been to the jurisdiction nor committed any acts there.”
Miller,
In this case, the government introduced ample evidence that numerous overt acts in furtherance of the methamphetamine distribution conspiracy took place in the District of Wyoming. Alvarado met his customers at stops along Interstate 80 to deliver drugs in both Utah and *1119 Wyoming. The testimony of several co-defendants corroborated this. For example, co-defendant Jason Freeman, who resided in Wyoming, testified that he would meet Alvarado in “Pilot in Evanston,” and “TA in ... Fort Bridger.” R., Vol. 3, Tr. 2 at 756, 763. When Freeman was shown a map marking various stops along 1-80 between Utah and Wyoming, R., Vol. 5 Ex. 103, Freeman testified that he recognized thе places outlined on the map. R., Vol. 3, Tr. at 764. One stop was marked “Evans-ton, WY.” Id.; R., Vol. 5 Ex. 103. Similarly, a point marked “TA Truckstop” was located in Wyoming. A reasonable jury could have inferred that Freeman met Alvarado in Evanston, Wyoming and at the TA Truckstop in Wyoming, where Alvarado distributed drugs in furtherance of the methamphetamine distribution conspiracy.
Additionally, Arnell, Alvarado’s first customer, lived in Lyman, Wyoming. R., Vol. 3 at 149. Alvarado sold drugs to Matthew Owens, also a resident of Lyman, Wyoming. Id. at 342-43. Alvarado met Owens for the first time at Arnell’s property in Wyoming and sold drugs to him at that meeting. Id. at 342-43, 345-46; R., Vol. 5 Ex. 103. Similarly, Alvarado met Landry for the first time at Arnell’s property in Wyoming and sold drugs to him at that meeting. R., Vol. 3 at 345-46; R., Vol. 5 Ex. 103. Alvarado testified that he continued to do business with Owens and Landry for the next three years. R., Vol. 3 at 346.
Thus, even assuming that Acosta-Gallardo never set fоot in the District of Wyoming, viewing the evidence in the light most favorable to the jury verdict, ample evidence was introduced showing that acts in furtherance of the conspiracy were committed there, making venue for Count One proper.
Count Eleven
Venue for Count Eleven presents a trickier question. Count Eleven, quoted
supra,
charges Acosta-Gallardo with using a telephone to facilitate the methamphetamine distribution conspiracy alleged in Count One, in violation of Title 21, United States Code, Section 843(b). Acosta-Gallardo argues that venue was not proper in the District of Wyoming because the phone calls that took place on September 12, 2009 and which form the basis of Count 11, occurred entirely within the state of Utah and never touched the District of Wyoming. The governmеnt does not dispute this fact. However, the government argues that venue is nonetheless proper in the District of Wyoming because the conspiracy facilitated by Aeosta-Gallardo’s phone call occurred in the District of Wyoming. The government argues that the Supreme Court’s decision in
United States v. Rodriguez-Moreno,
This issue presents a question of first impression for our circuit. Section 843(b) provides that “[i]t shall be unlawful for any person knowingly or intentionally to use any communication facility in committing or in causing or facilitating the commission of any act or acts constituting a [drug] felony ...” Because Section 843(b) does not contain an explicit venue provision, we must determine the place at which the crime was “committed” based on “the nature of the crime alleged and the location оf the act or acts constituting it.”
United States v. Cryar,
*1120
Our precedent has not previously held that a Section 843(b) offense is “committed” in any jurisdiction where the underlying drug felony was committed. Our circuit has previously described venue for an 843(b) offense as being appropriate “in both the district where the call was made and in the district where it was received.”
United States v. Goodwin,
No. 09-3316,
In
Rodriguez-Moreno,
the question before the Court was, where was venue proper for the offense of using or carrying a firearm “during and in relation to a crime of violence,” in violation of 18 U.S.C. § 924(c)(1).
To determine where the firearms offense was “committed,” the Court began with the proposition that “the
‘locus delicti
[of the charged offense] must be determined from the nature of the crime alleged and the location of the act or acts constituting it.’ ”
Id.
at 279,
The Court was also careful to distinguish its precedent in
Cabrales,
where it faced a similar question. In
Cabrales,
the defendant was charged with violating 18 U.S.C. §§ 1956 & 1957, which criminalize money laundering.
Our circuit has applied the reasoning of
Rodriguez-Moreno
to firearms offenses under Section 924,
e.g., United States v. Brown,
Notably, our circuit declined to extend the reasoning of
Rodriguez-Moreno,
to a prosecution under 18 U.S.C. § 1001(a)(2) for making a false statement “in any matter within the jurisdiction of the executive, legislative, or judicial branch” of the federal government.
United States v. Smith,
With these principles in mind, we review the language of Section 843(b) to determine the essential conduct elements of the offense. For a Section 843(b) offense, the government must prove that the defendant (i) “knowingly or intentionally” (ii) used “any communication facility” (iii) in “committing or in causing or facilitating the commission of any act or acts constituting [a drug felony].” 21 U.S.C. § 843(b). Thus, there are two conduct elements that the government must prove: first that the defendant used a communication facility, and second, that in doing so, the defendant committed, facilitated, or caused to be committed a drug felony.
That the commission of or facilitation of an underlying drug felony is a predicate offense to a Section 843(b) violation finds support in the Supreme Court’s decision in
Abuelhawa v. United States,
Our case law similarly requires a defendant to be complicit in an underlying drug felony for a Section 843(b) conviction to
*1122
stand. For example, in
United States v. Baggett,
our cоurt held that simple possession of heroin, punishable only as a misdemeanor, could not support a Section 843(b) conviction.
In the instant case, the underlying drug felony is a conspiracy. We have previously held that inchoate crimes such as attempt and conspiracy qualify as drug felonies that may underlie a Section 843(b) offense.
United States v. Reed,
Therefore, applying the reasoning of Rodriguez-Moreno, venue for prosecution of a Section 843(b) violation committed in furtherance of a conspiracy would be proper in any district where either the communication facility was used, or the underlying conspiracy was committed. In the instant case, because venue was proper in the District of Wyoming for the underlying drug felony (conspiracy to distribute methamphetamine), venue was proper there for the instant Section 843(b) offense.
Lack of Jury Venue Instructions
Acosta-Gallardo next argues that the district court’s failure to instruct the jury on venue constituted structural error that is per se reversible.
3
We note, however, that when a defendant has not requested a jury instruction on venue or has not objected to the lack of a speсific venue instruction at trial, we review only for plain error.
Kelly,
Under plain error review, a defendant must show “ ‘(1) an error, (2) that is plain, which means clear or obvious under current law, and (3) that affects substantial rights.’”
Id.
at 1238-39 (quoting
United States v. Goode,
*1123 4. Whether the evidence was sufficient to establish interdependence among Acostcir-Gallardo, Alvarado, and Alvarado’s Customers in Wyoming
Acosta-Gallardo next challenges the sufficiency of the evidence related to the conspiracy charge presented at trial to sustain his conviction for Count One. We review suffíciency-of-the-evidenee challenges de novo, “consider[ing] both direct and circumstantial evidence, and all reasonable inferences therefrom, in the light most favorable to the government.”
United States v. Wardell,
To prove a conspiracy, the government must show that “(1) two or more persons agreed to violate the law; (2) the defendant knew the essential objectives of the conspiracy; (3) the defendant knowingly and voluntarily participated in the conspiracy; and (4) the alleged coconspirators were interdependent.”
United States v. Yehling,
Acosta-Gallardo challenges only the interdependence fourth prong, arguing that he never spoke to or met co-defendant Robert Landry prior to trial. He also argues that his alleged co-conspirators— Kevin Watson, Charles Thunehorst, Brahnson Arnell, George Burkett, and Jason Freeman — were all cooperating witnesses for the government and that they testified that they purchased methamphetamine from either Landry or Alvarado, rather than from him. R., Vol. 3 at 451-58 [Watson testifying that he was purchasing drugs from Landry who was purchasing from a source unknown to him in Park City], R., Vol. 3 at 475-77 [Thunehorst testifying that he was buying drugs from Arnell, then from Alvarado starting in 2007]; R., Vol. 3 Tr. at 674 [Arnell testifying that his source was Alvarado], at 744-47 [Burkett testifying that he purchased methamphetamine from Landry], at 758 [Freeman testifying that he got methamphetamine from Alvarado]. Additionally, Acosta-Gallardo points out that Watson, Thunehorst, Arnell, and Burkett testified that they never knew or heard of AcostaGallardo. Aplt’s Br. 19 (citing R., Vol. 3 at 469 [Watson]; R., Vol. 3 Tr. at 658 [Thunehorst], 701 [Arnell], 776 [Freeman]).
These arguments, however, are unpersuasive because it is well-established that a сonspirator need not know of the existence or identity of the other members of the conspiracy or the full extent of the conspiracy.
See Evans,
Moreover, interdependence may be shown if a defendant’s activities “facilitated the endeavors of other alleged co-conspirators or facilitated the venture as a whole.”
United States v. Heckard,
Acosta-Gallardo’s argument that he and co-defendant Landry were not interdеpendent because they were involved in two separate conspiracies similarly fails. Acosta-Gallardo argues that Alvarado was involved in one conspiracy involving the purchase of drugs from three suppliers (of whom he was one), and in another conspiracy involving the distribution of drugs into the District of Wyoming. Whether sufficient evidence was presented to establish a single conspiracy is a question of fact for the jury to decide.
Dickey,
The government presented ample evidence of interdependence among AcostaGallardo, Alvarado, and their co-defendants. Acosta-Gallardo’s ability to profit from his sales of drugs to Alvarado depended on Alvarado’s ability to successfully sell the drugs to his customers, many of whom were in Wyoming. Drawing reasonable inferences in favor of the jury’s verdict, ample evidence existed to support the jury’s finding that Acosta-Gallardo and *1125 Landry were involved in a single conspiracy. Thus, Acosta-Gallardo’s sufficiency-of-the-evidence challenge fails.
Accordingly, we AFFIRM Acosta-Gallardo’s conviction.
Notes
. In his brief, Acosta-Gallardо suggested that the government also committed a Brady violation by failing to conduct a fingerprint analysis of the glass jars. Aplt’s Br. at 13-14. Counsel for Acosta-Gallardo clarified at oral argument that this argument was not at issue. Oral Argument 2:18 to 3:43. Accordingly, we do not address it.
