Eddiе David Cox appeals his convictions on twelve separate counts of drug trafficking and related offenses. He disputes: (1) the validity of a search of his vehicle; (2) the sufficiency of the evidence suрporting his convictions; (3) the nondisclosure of a witness cooperation agreement; and (4) *1284 the district court’s imposition of a $22,000 fine at sentencing. We reverse Cox’s conviction for conspiracy tо distribute cocaine and vacate the fine imposed thereon, but affirm his convictions and sentence in all other respects.
I. BACKGROUND
In July 1989, an anonymous citizen reported to the police department in Kansas City, Missouri, that an armed individual had brandished a weapon at the citizen and his daughter. 1 The citizen described the suspect’s vehicle as a maroon Lincoln Continental, license plate number LLN 135, which had stоpped at the corner of 36th and Walnut.
The police dispatcher contacted two patrol officers and told them to investigate a complaint about an armed individual driving a vehicle of thе above description at the above location. When the officers arrived at the intersection, they found Cox standing next to a red Ford LTD bearing the above license number. His vehicle had a flat tire. Thе driver’s side front door hung partly ajar.
The first officer on the scene frisked Cox, but found no weapons. The second officer to arrive went directly to the vehicle, opened the front door and searched under the driver’s seat. He found a gun, handcuffs and police scanner. This prompted further inquiry, during which Cox claimed to be an undercover DEA agent. He produced government identification that appeared authentic.
As Cox showed signs of intoxication, the officers ticketed him for drunk driving. They then released him, and returned his weapon, believing Cox to be a federal officer.
In August 1989, Cox and an unidentified black male entеred the home of Manuel Perez, holding themselves out as FBI agents. Cox demanded a kilogram of cocaine. When no kilogram was forthcoming, Cox searched the premises while the accomplice guarded the door. As a result of the search, Cox “confiscated” some $6,900 in cash, three ounces of cocaine and a revolver. Cox directed the operation and appeared to be in charge.
Cox returned to Perez’s residence three more times. On each occasion, Cox presented himself as a federal agent. On one occasion, Cox, accompanied by an unknown white male, took binoculars, a camera and a firearm. On another occasion, Cox left without incident. On the last occasion, Cox, accompanied by a black male, physically seаrched Perez but took nothing.
In September 1990, Cox approached a private security guard outside a bar. Cox identified himself as a DEA agent and inquired about the guard’s knowledge of local drug activity. He then left.
In a twelve-count indictment, the Government charged Cox with conspiracy to distribute cocaine (one count), possession with intent to distribute cocaine (one count), receiving a firearm as a сonvicted felon (two counts), interference with interstate commerce by threats of violence (Hobbs Act violations) (two counts), and impersonation of a federal officer (six counts). The jury returned convictions on all counts. The court imposed sentences (all concurrent) of life imprisonment on the conspiracy and firearms counts; thirty years on the possession with intent to distribute count; twenty years each on the Hobbs Act counts; and three years each on the impersonation counts.
This appeal followed.
II. DISCUSSION
A. Search of Vehicle
Cox first argues that the evidence discovered during the July 1989 drunk driving incident should have been suppressed because the police lacked justification for searching his vehicle. We disagree.
An anonymous tip corroborated by independent police work can carry suffi
*1285
cient indicia of reliability to provide reаsonable suspicion to make an investigatory stop.
Alabama v. White,
- U.S. -,
Once engaged in a lawful investigatory stop, the officers were entitled to conduct a protective sеarch of the surrounding area for weapons, given a reasonable belief that Cox posed a danger.
See Michigan v. Long,
B. Sufficiency of the Evidence
Much of Cox’s appeal focuses on the sufficiency of the evidence supporting the jury verdict. Well-established legal principles govern our review of challenges to a jury’s verdict. We will uphold a conviction if, taking the evidence most favorable to the Government, a reasonable jury could have found guilt beyond a reasonable doubt.
E.g., United States v. Wainright,
1. Drug Counts
With respеct to his drug convictions, Cox contends that the Government failed to establish the substance taken from the Perez residence as cocaine. He also contends that the Government failed to estаblish his intent to distribute the alleged cocaine, or that a conspiracy existed for that purpose.
As to substance identification, Cox relies heavily on the fact that no one from Perez’s apartment personally used or tested the taken substance. We nonetheless believe that the jury could infer that Cox acquired cocaine. Most significantly, Cox demanded cocaine from a known dealer, received the substance in question, and later came back demanding more cocaine.
We also think that the jury could infer Cox’s intent to distribute the taken substance. On several occasions, Cox went to the residence of a known drug dealer in search of drugs and drug paraphernalia. On at least one occasion, Cox demanded a large quantity of cocaine, inconsistent with personal use. Cox also made sizeable cash deposits in his bank account after this incident. Thus, the evidence, viewed most favorably to the Government, would permit a reasonable jury to return a guilty verdict on this count.
We cаnnot reach the same conclusion with respect to Cox’s conspiracy conviction, however. A conspiracy conviction requires a showing that the alleged individuals joined together to further an agreed-to criminal purpose: here, distribution-of cocaine.
See United States v. North,
We aptly heed the Supreme Court’s caution that “ ‘charges of conspiracy are not to be made out by piling inference upon inference.’ ”
Ingram v. United States,
2. Felon In Receipt Counts
Cox next asserts that the Government’s evidence fails to establish the intеrstate nexus for his firearm convictions beyond a reasonable doubt. Essentially, Cox posits that the Government must put the firearms in question into evidence. We disagree.
To prove an interstate nexus, the government must show that the firearm moved in or affected interstate commerce. 18 U.S.C.A. § 922(g) (West Supp.1991). The government need not produce the firearm in question to satisfy this element; proof that the firearm was manufaсtured outside the state of possession will suffice.
United States v. Gregg,
In the instant case, both eyewitness and expert testimony substantiated the interstate commerce element. The testimony of Government witnesses established thаt the weapons in question carried the rampant horse insignia of Colt Industries. The testimony further established that Colt does not manufacture weapons in Missouri. This evidence satisfies the interstate nexus requirement of section 922(g).
3. Hobbs Act Counts
Cox contends, among other things, that his robberies of the Perez residence lacked the requisite interstate nexus for a violation of the Hobbs Act, 18 U.S.C. § 1951 (1988). Based on the evidence at trial, we conclude that the Government sufficiently proved the interstate character of Perez’s drug trade.
Cf. United States v. French,
C. Disclosure
Cox also contends that the Government failed to disclose an alleged immunity agreement with Perez in violation of
Brady v. Maryland,
III. CONCLUSION
We reverse Cox’s conviction for conspiracy to distribute cocaine and vacate the fine imposed thereon, but affirm his convictions and sentence in all other respects.
Notes
. The record remains silent as to whether the citizen provided his name while making the initial complaint. Because the defense disputes this point, we assume for the purposes of analysis that no such identification occurred even though the citizen ultimately appeared at the scene of arrest and testified at trial.
