Timothy John Evans (Evans) appeals his conviction and sentence for conspiring to manufacture methamphetamine, in violation of 21 U.S.C. § 846. On appeal, Evans contends that (1) the government engaged in outrageous conduct which violated due process; (2) the evidence presented at trial was insufficient to support defendant’s conviction for conspiracy; (3) the absence of a government informant as a witness denied Evans a fair trial; and (4) his sentence was improper. Finding no basis for reversal, we affirm Evans’s conviction and sentence.
*270 I.
On July 6, 1988, Evans entered Scientific Chemicals, a public chemical supply store owned and operated by U.S. Drug Enforcement Administration (DEA) informant Ron Fernandez (Fernandez). While making a routine check of the store’s records, DEA agent Norris Rogers (Rogers) noticed Evans examining various equipment and precursor chemicals that could be used in the manufacture of methamphetamine. Rogers initiated a conversation with Evans. According to Rogers, Evans claimed to be a distributor and to have experimented with a small drug laboratory in his home. The two discussed the manufacture of methamphetamine and Rogers told Evans that he “could help him” manufacture methamphetamine for a price.
Following a meeting on July 7, Evans phoned Rogers on July 14 and again at the end of July to discuss the drug venture. 1 Rogers had no further contact with Evans until August 30, when Evans called Scientific Chemicals and left a message that he wanted to meet Rogers at the store. That evening, Evans and his co-defendant, Mike Lewis, met with Rogers and Fernandez. Evans gave Fernandez $1000 as a down payment for the equipment and supplies necessary to set up a “meth laboratory,” and he gave Rogers $500 to rent a laboratory site.
On September 8, Evans and Lewis again met with Rogers at Scientific Chemicals. DEA agent Gene Lewis was also present at this meeting. Agents Rogers and Lewis assisted Evans in selecting chemicals and equipment. The four men then proceeded to a motel to set up a laboratory, where the defendants ultimately were arrested. 2
A grand jury returned an indictment charging Evans and Mike Lewis with conspiracy to manufacture methamphetamine, and for possession of a firearm during a drug trafficking crime. Prior to trial, Evans filed several motions including a motion to dismiss the indictment or, in the alternative, for a continuance, based on Evans’s inability to subpoena Fernandez, the DEA informant. This motion was denied after the government argued that Fernandez’s testimony was unnecessary because other persons were available who could testify regarding the events that Fernandez witnessed. After a three-day jury trial, both defendants were found guilty on all counts. Evans was sentenced to 123 months imprisonment and three years supervised release. Evans filed a timely notice of appeal.
II.
A.
Evans first argues that the government engaged in “outrageous conduct” that deprived him of due process of law. Evans argues that the DEA agents approached him and offered to help him manufacture drugs, phoned him to pursue the arrangement, supplied the expertise, sold Evans the equipment, and supplied the laboratory site.
The Supreme Court recognized the defense of outrageous conduct in
United States v. Russell,
stating that “we may some day be presented with a situation in which the conduct of law enforcement agents is so outrageous that due process principles would absolutely bar the government from invoking judicial process to obtain a conviction.”
To successfully invoke the outrageous government conduct defense, the defendant must show that the challenged government conduct violated “that ‘fundamental fairness, shocking to the universal sense of justice,’ mandated by the Due Process Clause of the Fifth Amendment.”
Russell,
In
Tobias,
the DEA placed an advertisement in a magazine offering over-the-counter sales of chemicals and laboratory equipment. The defendant responded to the ad, requesting “more information.” After To-bias placed an order for chemicals, he telephoned to cancel his order because he discovered that he could not manufacture cocaine without more knowledge and equipment. The DEA agent suggested that the manufacture of Phencyclidene (PCP) would be easier. The agent sent Tobias information on the production of PCP and on thirteen occasions answered questions from Tobias and his wife regarding the PCP manufacturing process. When the DEA executed a search warrant on Tobias’s house, they found liquid PCP.
In the present case, there is more than enough evidence to establish that Evans was a “predisposed active participant” based on his past drug activities, his investigation into the processes by which drugs are made, and his active participation in the scheme for which he was convicted. There is evidence in the record that Evans purchased the glassware and chemicals required for the manufacture and made diligent notes on the agent’s manufacturing process instructions for future reference. Thus, we cannot say that he played a “passive role.” 3
B.
Evans next argues that the government failed to establish that a conspiracy existed between Evans and Mike Lewis. Evans contends that there was insufficient evidence that Evans and Lewis knowingly and voluntarily agreed to participate in a conspiracy to manufacture methamphetamine. Rather, Evans contends that Lewis was merely present at the meetings between Evans and the agents for security and was not a “true conspirator.”
In reviewing a challenge to the sufficiency of evidence to support a conviction, this court must affirm a conviction if- any rational fact-finder could have found each of the essential elements of the crime beyond a reasonable doubt.
United States v. Alvarado,
Although “mere presence” at the scene of a crime will not support an inference of participation in a conspiracy, it is a “significant factor to be considered within the context of the circumstances under which it occurs.”
United States v. Medina,
C.
Evans next contends that he was denied a fair trial because the testimony of an allegedly material witness, Fernandez, was unavailable. Evans contends that Fernandez’s absence was significantly prejudicial to Evans because Fernandez was a material witness regarding Evans’s outrageous government conduct defense, his testimony would have been relevant to an entrapment defense, and Fernandez could further demonstrate the lack of a conspiracy.
In reviewing the government’s obligation to disclose the identity and whereabouts of government informers, a court must “balanc[e] the public interest in protecting the flow of information against the individual’s right to prepare his defenses.”
Roviaro v. United States,
This is not a case in which the informant’s identity is unknown, but rather a case in which the informer has changed his name, and his address has become unavailable immediately prior to trial. Nonetheless, the above analysis provides guidance for the adjudication of this challenge.
See Fischel,
D.
Last, Evans challenges his sentence because he contends that it is based on erroneous, immaterial information. Evans argues that the only type of drug that could have been produced with the chemi *273 cals available at Scientific Chemicals was Levo-methamphetamine, “a stereoisomer version of methamphetamine.” The United States Sentencing Guidelines (U.S.S.G.) provide a lower sentencing level for Levo-methamphetamine than that used by the district court in computing Evans’s sentence based on methamphetamine. Evans’s appellate counsel, assisted by an expert organic chemist, makes a detailed argument on this basis. This challenge, however, was not raised by Evans at trial or during the sentencing proceedings. No witness testified to the defendant’s theory at either juncture so as to create a record upon which we could base our review. Based on the lack of evidence in the record to establish any error, there are no grounds upon which to reverse the district court on this issue.
Evans also challenges his sentence because he contends that it is based on the amount of drug that the government agents predetermined by its supply of chemicals and the capacity of the glassware provided by the government. Again, this challenge was not raised at trial. Evans argues that this court has previously found plain error in the determination of a defendant’s sentence when the government has supplied the chemicals used in a drug conspiracy.
Tobias,
The district court’s sentence was in line with U.S.S.G. § 2D1.4 which “permits the court to examine the overall scheme and to infer circumstantially either the total drug quantity involved in the offense or the capability of its production.” The discretion retained by the district court under § 2D1.4 allows the court to review the government’s prosecution and to prevent any outrageous manipulation of the drug amount. This is consistent with our recent analysis in a similar situation — when the government engages in a money laundering sting operation.
See United States v. Richardson,
III.
Based on the foregoing, we affirm Evans’s conviction and sentence.
AFFIRMED.
Notes
. There was conflicting testimony regarding whether Evans or Rogers initiated phone calls which discussed the operation and the extent to which Rogers pushed the project.
. DEA agents videotaped the proceedings in the hotel room from an adjacent room. Agents Rogers and Lewis gave Evans step by step instructions on how to produce the drug; they instructed Evans on how to set up the equipment, and on the ingredients and ratios required for producing "meth.” The DEA Agents testified, however, that although they told Evans that they were producing methamphetamine, they actually mixed the chemicals to make a non-controlled substance.
. We note that the U.S. Supreme Court has recently granted certiorari in a case in which the defendant asserted the
Russell
outrageous government conduct defense.
