Gregory Sykes appeals from judgments of conviction entered by the district court 1 after a four-day jury trial. He was convicted of conspiring to distribute 169 grams of phencyclidine (“PCP”), a schedule II controlled substance, in violation of 21 U.S.C. § 846, and of using a firearm in the commission of the drug trafficking crime, in violation of 18 U.S.C. § 924(c). On appeаl, Sykes raises a total of seven issues. He argues that: (1) the district court erred in allowing the government case agent to sit at the prosecution table and to testify as an expert; (2) the court erred by disallowing the disclosure of a confidential informant’s identity; (3) the court erred in allowing evidence of another crime to be heard; (4) the court erred in submitting the 21 U.S.C. § 846 charge to the jury; (5) the court erred in submitting the 18 U.S.C. § 924(c) charge to the jury; (6) there was improper contact between the government’s case agent and members of the jury; and (7) the court erred in sentencing. We affirm.
I.
Acting pursuant to a tip from a confidential informant, Minnesota Bureau of Criminal Apprehension Special Agent Eugene Leatherman investigated an alleged PCP trafficking scheme involving Sykes and one Douglas Smieja in November 1990. Agent Leatherman obtained a search warrant for Sykes’ residence on November 19, 1990, and executed the warrant that evening. In the basement of Sykes’ residencе, police found 169 grams of liquid PCP, an electronic scale, a pager, and three firearms. In an upstairs bedroom, police also found $870 in cash.
At trial, two witnesses testified for the government under subpoenas and grants of immunity. These witnesses indicated that they had obtained PCP from Sykes in exchange for either money or othеr material items many times in the preceding six *1245 months. They testified that the transactions took place in Sykes’ basement. One witness had actually obtained PCP from Sykes on November 19, 1990, the day of the search.
Witnesses also introduced evidence at trial connecting Sykes with a large amount of PCP after November 19, 1990. These witnesses testified that Montclair, California police officers, acting pursuant to a search warrant, had found 173 grams of PCP in a hotel room registered to Sykes on July 5, 1991.
II.
A. Government Case Agent as Witness
Sykes argues that the district court committed reversible error by allowing Special Agent Robert Bushman, who was appointed as the government’s case agent, to sit at the prosecution table throughout the trial and then to testify as an expert.
Federal Rule of Evidence 615 provides that witnesses may be excluded from hearing the testimony of other witnesses. Rule 615, however, contains exceptions. Federal Rule of Evidence 615(2) states that the rule does not authorize the exсlusion of “an officer or employee of a party which is not a natural person designated as its representative by its attorney.” The Senate Judiciary Committee’s notes to this rule specifically provide that this exception should be interpreted to allow government case agents to remain at thе counsel table throughout the trial. Fed.R.Evid. 615 judiciary committee’s notes.
[1] The decision whether to allow the government’s agent to testify even though the agent sits at the counsel table throughout the trial is left to the trial court’s discretion.
United States v. Williams,
In order to show an abuse of discretion by the trial court, Sykes must show prejudice.
United States v. Woody,
B. Disclosure of Informant’s Identity
The decision whether to release an informant’s identity is governed by an abuse of discretion standard.
United States v. Harrington,
In order to obtain disclosure, the defendant has the burden of showing that disclosure would be material and helpful to his case.
Johnson,
C. Evidence of Other Crimes
Sykes asserts that the court erred in allowing a Montclair, California police officer and a chemist analyst to testify regarding an unrеlated alleged drug crime involving Sykes on July 5, 1991. These two witnesses testified that 173 grams of PCP had been found in Sykes’ hotel room.
The government introduced this testimony pursuant to Federal Rule of Evidence 404(b). This rule provides that evidence of other crimes may be admitted only for limited purposes, such as showing motive, intent, opportunity, or knоwledge. Fed.R.Evid. 404(b). This court has established a four-part test for determining admissibility of Rule 404(b) evidence. Such evidence is admissible if it is “(1) relevant to a material issue; (2) of crimes similar in kind and reasonably close in time to the crime charged; (3) sufficient to support a jury finding that the defendant committed the other crimes; and (4) more probаtive than prejudicial.”
United States v. Yerks,
The admission of Rule 404(b) evidence regarding the California offense was appropriate in this case. The possession of almost exactly the same amount of PCP in California was relevant in showing that Sykes possessed the required knowledge and intent for the present offense. Thе California crime was virtually identical to the present crime and occurred only eight months later.
2
Moreover, the two California witnesses provided sufficient evidence to support a finding that Sykes committed a crime on July 5, 1991. Finally, the evidence was more probative than prejudicial. In this case, the district court gave abundant instructions that the Rule 404(b) evidence was offered only for a limited purpose. These limiting instructions served to minimize the likelihood that prejudice would occur.
United States v. Gustafson,
D. 21 U.S.C. § 846 Conspiracy Charge
Sykes argues that the conspiracy conviction is insupportable because there was no evidence that Sykes ever possessed the PCP and Sykes contends that all the evidence in the case implicates his co-defendant Smieja alone. We disagree.
In reviewing a jury verdict, this court must affirm if there is substantial evidence to support the verdict.
Glasser v. United States,
Sykes was not charged with a possession offense, but with a сonspiracy count. 21 U.S.C. § 846 states that “[a]ny person who attempts or conspires to commit any offense defined in this title shall be subjected to the same penalties as those prescribed for the offense, the commission of which was the object of the attempt or conspiracy.” Distribution of PCP is an offense referenced by § 846.
See
21 U.S.C. § 841(a). To be guilty of a conspiracy, a defendant need only knowingly contribute his efforts in furtherance of the conspiracy.
United States v. Fanello,
E. 18 U.S.C. § 924(c) Gun Charge
Sykes argues that there was insufficient evidence to support his conviction on the charge of using a firearm in connection with a drug trafficking crime.
Testimony at triаl indicated that drug transactions had taken place in the basement of Sykes’ home. It is undisputed that Gregory Sykes was living in this house along with his parents, who owned the home. The defense also offered testimony that Sykes’ co-defendant, Douglas Smieja, was living in the house as well. The prosecution witnesses testified that the drug transactions had taken place at a table in a living area located in the basement. Both prosecution and defense witnesses also testified that the basement contained a separate bedroom. The bedroom contained a gun cabinet with sliding glass doors in which investigators found an unloaded .32 caliber Colt revolver resting on a shelf. The gun cabinet also had a drawer below the compartment enclosed by the glass doors. The Colt revolver found in the upper part of the gun cabinet is the basis for the 18 U.S.C. § 924(c) charge.
The government offered photograph exhibits, accompanied by testimony, which showed that the sliding glаss doors of the gun cabinet were both pushed to one side, leaving the revolver readily accessible at the time of the search on the evening of November 19, 1990. The government also submitted photos and testimony showing that there were small amber bottles in the bedroom containing liquid PCP within three feet of the revolver.
Thе defense, however, offered testimony implying that the glass doors of the gun cabinet were locked on November 19, 1990. The defendant’s mother testified that the lock which was originally on the sliding glass doors was missing after the search on November 19. She testified that she found a metal cross-bar which was part of the glass door locking mechanism at the bottom of the gun cabinet after the search, but she could not find the rest of the lock. After November 19, 1990, upon defense counsel’s instructions, Mrs. Sykes purchased a new lock mechanism for the glass gun cabinet doors, installed it, and then took photographs of the locked cabinet. These photоs, taken after the date of the search, were submitted as defense exhibits. Based on this evidence, the defense contends that the gun cabinet was locked on the night of the 19th as well. 3

18 U.S.C. § 924(c)(1) states in relevant part: “Whoever, during and in relation to any crime of violence or drug trafficking crime ... for which he may be prosеcuted in a court of the United States, uses or carries a firearm, shall, in addition to the punishment provided for such crime of violence or drug trafficking crime, be sentenced to imprisonment for five years.... ” The phrase “uses or carries” has been interpreted in many cases from this circuit. This court has recognized “the utility of firearms in advancing criminal adventures in narcotics.”
United States v. LaGuardia,
It is inconsequential that the gun was located in a different room from where the drug transactions occurred. This court has stated, “[t]he fact that a gun is located in a room that is not the center оf drug transactions does not preclude the possibility that a drug dealer intended to use it to support his operations.... The key is always whether the placement of the gun or guns suggests they would be quickly available for use in an emergency.”
United States v. Lyman,
The jury needs only to find a “sufficient nexus” between a gun and drug trafficking in order to sustain a § 924(c) conviction.
United States v. Watson,
F. Improper Jury Contact
Sykes claims that government case agent Bushman improperly was allowed to take exhibits into the jury room and to walk down a stairwell with the jury foreman. Sykes, however, has offered nothing in the record to substantiate these statements. This court cannot give credence to bald assertions which have no support in the record on appeal.
G. Sentencing
Sykes also claims that the court erred in sentencing. He argues that the court did not follow the suggested guidelines and recommendations of the United States Probation Office. He also claims that the Probation Office submitted a separate “confidential” letter to the district court. Sykes’ counsel contends that he did not have access to this alleged letter and was not aware of its existence until after the close of sentencing.
After a careful review of the record, we find that Sykes’ claims are wholly without merit. The district court applied the statutory minimum of 120 months for the PCP *1249 trafficking offense, and an additional 60 months which is the statutory minimum for the gun оffense. This sentence was entirely appropriate. Furthermore, there is no support in the record for Sykes’ contention that the Probation Office sent a letter to the district court. Accordingly, the district court did not err in sentencing Sykes.
III.
For the foregoing reasons, the convictions and Sykes’ sentence are affirmed.
Notes
. The Honorable David S. Doty, United States District Judge for the District of Minnesota.
. Evidence of subsequent acts is allowable under Rule 404(b).
See United States v. Luttrell,
. In response to a direct question at oral argument, Sykes’ counsel asserted that the entire gun cabinet was locked on November 19, 1990. Upon request of this court, counsel later suppliеd a list of 16 citations to the trial transcript which he offers, in part, to support his conten *1248 tion that the glass doors were locked. This court has carefully reviewed each of these references. These citations to the transcript do not in any way support the conclusion that the doors to the gun cabinet were locked on November 19, 1990.
