Defendant, Alberto Hernando Narvaez (Narvaez), appeals the district court’s: (1) refusal to allow Narvaez to present all of his witnesses at the sentencing hearing; (2) im *164 position of a four-level increase in the base offense level for role in the offense; and (3) imposition of a two-level enhancement for obstruction of justice. For the reasons discussed below, we affirm.
I. BACKGROUND
Narvaez was introduced to a confidential informant and told the informant that he (Narvaez) had a supplier who had 1,000 kilos of cocaine. Later, Narvaez directed the informant to perform a series of cocaine delivery-related activities. Under the direction of Narvaez, the informant made a delivery under surveillance, and agents followed the de-liveree’s Ford to an apartment. Codefend-ant Luis Obregon, a Colombian, arrived with an “unknown black male”; the latter retrieved the cocaine from the Ford and placed it in Obregon’s vehicle. Obregon was later arrested, and a search of his vehicle produced cocaine.
Narvaez then directed the informant to deliver the remaining cocaine to codefend-ants Ramirez and Colon. An undercover agent delivered the cocaine to Ramirez, Colon, and codefendant Martin Mejia Molina. The three codefendants were arrested when the cocaine was put into their vehicle. Ramirez told authorities that Narvaez, as before, had directed him to pick up the cocaine from the informant.
Narvaez later contacted the informant and directed her to obtain a copy of the police report concerning the aforementioned arrest. Narvaez was arrested when he appeared to pick up the arrest report. The probation officer concluded and the district judge agreed that, based upon the information provided by the informant, Narvaez was the leader or organizer of this criminal activity. This led the district court to assess a four-level enhancement to Narvaez’s base offense level.
At the detention hearing F.B.I. agent Lemoine testified that two independent and reliable sources provided information that Narvaez had issued a contract for the death of the confidential informant. This testimony was corroborated by the informant who personally learned of this fact from an acquaintance. As both the government and the informant were made aware of the existence of this threat to the informant’s life, the informant and her family were relocated by the government. Based upon this threat and corroborating testimony, the district court assessed a two-level enhancement to his sentence for obstruction of justice.
Before sentencing, Narvaez filed several Ex Parte Applications for Writ of Habeas Corpus Ad Testificandum, requesting that Colon, Molina, Ramirez, and Obregon be allowed to testify at the sentencing hearing. With regard to all defendants except Obre-gon, who was being sentenced at the same time as Narvaez, the district court denied the motions, ruling, inter alia, that “[fjactual assertions by the probation officer which are contravened by Narvaez are based on the investigative reports, matters brought out at the detention hearing, and the facts admitted as true at the time the defendants pleaded guilty.” The district court noted that Colon was found to be incompetent to stand trial and was being deported, and that Molina and Ramirez had already been sentenced and were in transit to their respective places of incarceration.
At sentencing, the district court permitted Narvaez to introduce testimony of agent Lemoine who could not recall whether anyone, including Obregon, stated that Narvaez was a manager or supervisor, but noted that Molina had told another officer that it was Narvaez who had instructed Ramirez and Molina to pick up the cocaine. Obregon was then allowed to testify, stating that, before his arrest, he had never seen nor spoken to Narvaez and that Narvaez had not supervised him or given him any instructions.
Narvaez pled guilty to one count of conspiracy to possess cocaine with intent to distribute in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(B) and 846. It was determined that Narvaez had a base offense level of 34 combined with a four-level enhancement for his role in the offense, a two-level enhancement for obstruction of justice and a three-level reduction for acceptance of responsibility. Accordingly, the district court calculated the offense level at 37, and sentenced Narvaez to 210 months in a guideline range of 210 to 262 *165 months followed by a 60 month term of supervised release. Narvaez filed a timely notice of appeal.
II.STANDARD OF REVIEW
The appropriate standards of review are as follows: (1) abuse of discretion by the district court for not allowing Narvaez to call the eodefendant witnesses; (2) clearly erroneous for the district court’s finding that Narvaez was an organizer in the offense; and (3) clearly erroneous for the district court’s finding that Narvaez obstructed justice.
III.WHETHER THE DISTRICT COURT ABUSED ITS DISCRETION WHEN IT REFUSED TO ALLOW NARVAEZ TO PRESENT ALL OF HIS WITNESSES AT THE SENTENCING HEARING
Narvaez argues that the district court violated Federal Rule of Criminal Procedure 32(c) and § 6A1.3 2 of the Sentencing Guidelines by not allowing the testimony of several codefendants at the sentencing hearing. As this decision falls squarely within the discretion of the district court, Narvaez must prove the district court abused its discretion in order to overturn the ruling. See Fed. R.Crim.P. 32(c)
This Circuit has held that a presentence report generally bears sufficient indicia of reliability to be considered as evidence by the trial judge in maMng the factual determinations required by the sentencing guidelines.
United States v. Alfaro,
From the record provided, this court finds the district court had ample knowledge and understanding to disallow the requested testimony. Thus, this court holds the district court did not abuse its discretion in disallowing the testimony requested by Narvaez. We affirm.
IV.WHETHER THE DISTRICT COURT’S FINDING THAT NAR-VAEZ WAS AN ORGANIZER IN THE OFFENSE WAS CLEARLY ERRONEOUS
If the defendant was an organizer or leader of a criminal activity that involved
*166
five or more participants or was otherwise extensive, a four-level enhancement is appropriate. U.S.S.G. § 3Bl.l(a). The district court’s decision to increase defendant’s offense level by four (pursuant to Guidelines § 3B1.1) for defendant’s aggravating role in the transaction is a finding of fact that this court will review only for clear error.
United States v. Rodriguez,
... [t]he exercise of decision making authority, the nature of participation in the commission of the offense, the recruitment of accomplices, the claimed right to a larger share of the fruits of the crime, the degree of participation in planning or organizing the offense, the nature and scope of the illegal activity, and the degree of control and authority exercised over others.
U.S.S.G. § 3B1.1 comment, (n. 4). There must be an acceptable evidential basis for the court’s factfindings at the sentencing hearing.
United States v. Rodriguez,
The district court found Narvaez to be involved with the requisite number of five individuals to merit the four-level enhancement as an organizer. Narvaez contends this to be erroneous based on the district court’s inclusion in the numerical assessment of the informant and Mr. Colon. However, the district court may consider unidentified participants when there is proof that they were involved in the precise transaction underlying the conviction.
United States v. Barbontin,
The district judge determined Narvaez, Ramirez, Obregon, an “unknown black male”, and Molina individually and cumulatively participated in the transaction before the court. This court finds that there is ample evidence to support the district judge in his numerical assessment of the participants. This court finds further that based upon the totality of the evidence taken from the detention hearing, the presentence report and the sentencing hearing, the district judge did not intend to characterize, Narvaez as a manager for the purposes of sentencing. Rather, the district judge utilized this title as nomenclature to better describe the overall activities of Narvaez. This court finds that the district judge did indeed intend to characterize Narvaez as an organizer and the imposed sentence reflected this intent. We affirm.
V. WHETHER THE DISTRICT COURT’S FINDING THAT NAR-VAEZ OBSTRUCTED THE ADMINISTRATION OF JUSTICE WAS CLEARLY ERRONEOUS
The United States Sentencing Guidelines mandate a two-level enhancement from a base level where the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice during the investigation, prosecution, or sentencing of the instant offense. U.S.S.G. § 3C1.1. Such conduct may include threatening, intimidating, or otherwise unlawfully influencing a witness, directly or in
*167
directly, or attempting to do so. U.S.S.G. § 3C1.1, comment, (n. 3(a)). Under this section, the defendant is accountable for his own conduct and for conduct that he aided, or abetted, counseled, commanded, induced, procured, or willfully caused. U.S.S.G. § 3C1.1, comment, (n. 7). The district court relied upon the evidence presented at the detention hearing in determining that Nar-vaez had violated this provision by placing a contract on the life of the informant. It is appellant’s responsibility to order parts of the record which he contends contain error and his failure to do so prevents us from reviewing this assignment of error.
Brookins v. United States,
However, in order to fully adjudicate the issue, this court entertained Narvaez’s contention that the witness be aware of the threat or have some likelihood of learning of the threat.
United States v. Brooks,
The district court’s findings of fact concerning an obstruction increase are reviewed under a clearly erroneous standard.
United States v. Franco-Torres,
VI. CONCLUSION
We AFFIRM the sentencing decision of the district court.
