Andres Romero appeals his drug conspiracy related convictions, arguing that the evidence was insufficient to support venue in the District of Minnesota because his aetivi *823 ties were confined to the state of Florida. We affirm.
I.
Andres Romero, a Florida resident, was arrested in Florida for supplying cocaine to several smaller cocaine traffickers in Minnesota. The evidence at trial showed the following. In May or June 1990, Neil Connelly, a Minnesota resident and cocaine trafficker, drove to Florida to obtain cocaine for his Minnesota customers from a long-time acquaintance, Greg Clark. Clark called Romero to see if Romero could supply the cocaine Connelly wanted; Clark said that he told Romero he had “friends that were in the business from Minnesota, or from the north, and that they were interested in buying cocaine.” (Trial Tr. at 262.) From then on, Romero regularly supplied Clark with all the cocaine needed to satisfy Connelly and his Minnesota customers. Connelly made monthly trips to Florida to purchase the cocaine, which he would transport back to Minnesota for further distribution. Romero began fronting the cocaine (that is, providing it on credit) to Clark, who would then repay Romero after receiving payment from Con-nelly.
After Connelly died in 1995, Doug DeMal-ignon, another Minnesota resident and prior acquaintance of Clark, took over Connelly’s Minnesota drug trade operation. The operation continued, but at this point, Clark began personally transporting the cocaine (approximately four to ten kilograms a trip) to Minnesota every six to eight weeks. For each kilogram, Romero charged Clark between $22,000 and $26,000, and Clark added one to two thousand dollars to the price when he in turn sold it to DeMalignon. Romero continued fronting these large amount's of cocaine to Clark in Florida, and Clark fronted the cocaine to DeMalignon in Minnesota, thereby deferring DeMalignon’s payment until Clark’s next trip to the north. Sometimes DeMalignon would send the money to Clark one or two weeks later by UPS delivery. DeMalignon’s customers included Mike Jones, Bob Cory, James McCann, and Charles Turner, most of whom would purchase one or two kilograms of cocaine at a time from DeMalignon. Clark delivered a total amount of approximately 60 kilograms of cocaine to DeMalignon.
The investigation leading to Romero’s arrest began on July 25, 1996, when local law enforcement officers in Minnesota arrested Peter Vitale, who, along with David Mathi-son, was one of James McCann’s customers. Vitale agreed to cooperate and arranged a controlled buy of two kilograms of cocaine from McCann at a price of $57,000. After McCann accepted the money, officers arrested McCann, and he agreed to cooperate. McCann implicated DeMalignon as his source, and officers then arrested DeMalig-non as well. DeMalignon agreed to cooperate, identifying his customers and identifying Clark as his source of cocaine. Officers directed DeMalignon to arrange a deal with Clark, requesting from him as much cocaine as possible. After DeMalignon contacted Clark, Clark arranged a meeting with Romero to obtain the cocaine. He obtained 11 kilograms of cocaine from Romero in Florida and drove to Minnesota with it hidden inside his ear. Officers arrested Clark in Minnesota when he attempted to deliver the 11 kilograms of cocaine to DeMalignon. Like the others, Clark also agreed to cooperate with the law enforcement officers. He named Romero as his source.
At the direction of law enforcement officers, Clark arranged a meeting with Romero in Miami, Florida, to obtain cocaine and to pay Romero approximately $249,000, which he owed for cocaine that Romero had previously fronted him. Clark told Romero he could not meet until the following afternoon, because he was “waiting for money to come from up north.” (Trial Tr. at 300.) Romero agreed to the meeting, saying he had “new product” available. (Id.) The meeting the next day was taperecorded and videotaped. Without mentioning the word cocaine, Clark and Romero discussed the price and quality of the product. Clark inquired about when he could get more and how much Romero had available. Romero told Clark he could provide three kilograms that day and that it was better quality than “the previous.” (Id. at 303.) Clark brought a suitcase to the meeting purporting to contain the $249,000 *824 he owed Romero, though in reality it contained only magazines. Law enforcement officers arrested Romero when he took the suitcase from Clark’s car and seized three kilograms of cocaine from Romero’s condominium in Miami.
The government charged Romero, Clark, DeMalignon, McCann, Jones, Turner, Cory, Vitale, and Mathison with conspiracy to distribute and to possess with intent to distribute in excess of five kilograms of a mixture or substance containing a detectable amount of cocaine, in violation of 21 U.S.C. §§ 846 and 841(b)(l)(A)(ii) (1994). Additionally, the government charged Romero with aiding and abetting Greg Clark in possessing approximately 11 kilograms of cocaine with intent to distribute, in violation of 21 U.S.C. §§ 841(a)(1) and 841(b)(l)(A)(ii), and 18 U.S.C. § 2. Romero stood trial before a jury in the District of Minnesota with one. other defendant. Clark and DeMalignon entered into plea agreements and testified against Romero. Romero was convicted on both counts against him. The district court 2 sentenced him to a term of 188 months of imprisonment, and Romero appeals.
II.
A.
Romero’s first contention is that venue in Minnesota was not proper for the conspiracy charge, because the proof offered at trial did not demonstrate that he was involved in a drug conspiracy in Minnesota.
“ ‘Proper venue is required by Article III, § 2 of the United States Constitution and by the [S]ixth [A]mendment, as well as Rule 18 of the Federal Rules of Criminal Procedure.’”
United States v. Granados,
Romero argues that the government did not prove the conspiracy it charged, but two separate conspiracies — one in Minnesota involving Clark, DeMalignon, and all the Minnesota customers and a separate one in Florida involving a buyer-seller arrangement between Clark and Romero. Romero concedes that he was part of an agreement to distribute drugs to Clark in Florida. (Appellant’s Br. at 21 (arguing, “Romero’s ‘agreement’ was to distribute drugs to Clark in Florida”).) Nevertheless, he maintains he was not part of the Minnesota conspiracy because he did not know the Minnesota people, he had no direct involvement or connection with anyone in Minnesota, and he had no knowledge of Clark’s distribution activities in Minnesota. Thus, he contends, there is no evidence to support venue in Minnesota. We disagree.
“To prove that a defendant was a member of a conspiracy to manufacture or to distribute illegal drugs, the government must demonstrate (1) that there was a conspiracy, i.e., an agreement to manufacture or to distribute, (2) that the defendant knew of the conspiracy, and (3) that the defendant intentionally joined the conspiracy.”
United States v. Hester,
In this case, the district court instructed the jury to determine whether there was a single conspiracy involving participants in both Minnesota and Florida or two separate conspiracies (one in Florida and one in Minnesota). The district court correctly instructed that if the government did not prove that the defendant was a member of the conspiracy charged in the indictment, the jury must find him not guilty on the conspiracy charge. (Instr. 10, Clerk’s R. at 82.) The jury found one single conspiracy and convicted Romero. “In determining whether a single or multiple conspiracy exists, we view the evidence in the light most favorable to the jury’s verdict.”
United States v. Cabbell,
Viewing the evidence in the light most favorable to the verdict, we conclude that the evidence was sufficient for the jury to find that the government proved a single conspiracy and that the record therefore demonstrates venue was proper in Minnesota. We note initially that the government presented ample evidence proving the existence of a conspiracy involving Clark and the Minnesota customers and proving that m'any acts in furtherance of this conspiracy took place in both Minnesota and Florida. “Once a conspiracy has been proven, even ‘slight evidence’ of a defendant’s participation is sufficient to support a conviction.”
Dolan,
Romero sold large quantities of cocaine to Clark to satisfy the Minnesota customers and also fronted large amounts to Clark, apparently confident that Clark would return with the money after his next distribution trip to Minnesota. In this manner, Romero had a financial interest in the conspiracy, which was dependent upon Clark receiving payment from customers in Minnesota who were further down the chain of distribution. Romero argues that Clark was obligated to pay him regardless of whether the Minnesota customers paid, and that therefore he had no financial interest that was dependent upon the Minnesota conspiracy. This argument, however, attempts to bring a sense of contractual legitimacy into Romero’s illegitimate relationship with Clark, which simply cannot exist with regard to contraband.
Romero attempts to show that he was not part of the conspiracy by noting that he knew no one in Minnesota and no one in Minnesota knew that he was Clark’s source. It is immaterial that Romero did not know all of the participants in the conspiracy or that the customers in Minnesota did not know him. The evidence demonstrates that the participants were all working together in furtherance of the object of the conspiracy— cocaine distribution from Florida to Minnesota — in spite of the fact that they did not all know of each other. “Neither the law, nor logic, requires that all of the conspirators know each other or the full extent of the conspiracy’s reach.”
United States v. Slaughter,
We reject Romero’s contention that he was not part of the Minnesota conspiracy because his relationship with Clark was that of a mere buyer and seller in Florida. Romero correctly asserts that we have held that “a mere sales agreement between a buyer and seller with respect to contraband does not constitute a conspiracy.”
United States v. Jensen,
Romero also asserts that the district court erred by not submitting to the jury an instruction on venue for the conspiracy count. The non-submission of such an instruction does not require reversal in this case. While “[v]enue is ordinarily a question of fact for the jury,” “when the evidence clearly shows that the events underlying a charged offense occurred in a particular jurisdiction, the failure to give the jury a venue instruction may be harmless error.”
Bascope-Zurita,
We note that our analysis on the venue issue is not altered by the Supreme Court’s recent decision in
United States v. Cabrales,
— U.S. —,
B.
Romero’s second argument is that the government did not prove venue in Minnesota was proper on the count charging him with aiding and abetting Clark’s possession of cocaine in Minnesota. The district court included a venue instruction on this count. Although Clark was arrested in Minnesota while in possession of 11 kilograms of cocaine,. Romero contends that he had no part in aiding or abetting Clark’s possession of the cocaine in Minnesota because he actually transferred the cocaine to Clark in Florida.
“[A]n aider and abetter may be tried in the district in which the principal committed the substantive crime.”
United States v. Buckhanon,
III.
For the reasons stated above, we affirm the judgment of the district court.
