Pеrcio Reynoso appeals from a judgment of conviction and sentence imposed under 21 U.S.C. §§ 841(a)(1) & 846. The evidence introduced at trial established that Reynoso and Benjamin Valera conspired to distribute cocaine at Valera’s store in Providence, Rhode Island, and were arrested there on March 29, 2001, immediately following a drug sale to a confidential informant for the Drug Enforcement Administration (DEA). In due course Reynoso was indicted for conspiring to distribute, and distributing, a controlled substancе. See 21 U.S.C. §§ 841(a)(1), 846. Following trial, the jury returned guilty verdicts against Reynoso on each count, and the district court imposed a 109-month term of imprisonment. Reynoso now appeals. We affirm.
A. The Speedy Trial Act
Reynoso first contends that he was brought to trial more than seventy days after his indictment, in violation of the Speedy Trial Act (STA), 18 U.S.C. §§ 3161(c)(1), 3161(h), 3162(a)(2). Conclusions of law under the STA are rеviewed
de novo;
findings of fact for clear error only.
United States v. Scott,
Although Reynoso asserts that seventy-one days were non-excludable under the STA, the instant, appeal must fail if any one of the seventy-one days is determined excludable under the STA. We now turn to that analysis.
On August 1, 2001, the STA clock was tolled upon the empanelment of the trial jury.
See United States v. Rodriguez,
B. The Motion to Suppress
Reynoso next contends that his signed confession should have been suppressed because the DEA agents (i) failed to accord him
Miranda
warnings, either in Spanish or in English, (ii) threatened him with deportation, (in) declined his request to consult counsel, and (iv) recruited Val-era to cajole him into confessing. Findings of fact made in relation to a motion to suppress are reviewed only for clear error.
United States v. Rosario-Diaz,
The district court was presented with conflicting testimony regarding each of these occurrences. Moreover, as the primary arbiter of witness credibility, the district court acted well within its prerogative in discrediting the version of the relevant events positеd by Reynoso.
See United States v. Laine,
C. The Expert Testimony
At the time of the arrest, the DEA agents seized 110 grams of cocaine from Reynoso’s automobile, which was parked near Valera’s store. During trial, Reynoso maintained that so “small” an amount оf cocaine plainly was intended exclusively for personal use, rather than distribution. Reynoso now challenges the admission into evidence of the expert tеstimony of DEA Agent Kathleen Kelleher — that the quantity of cocaine seized from Reynoso’s car was too large to have been exclusively for his personal use — given that Agent Kelle-her concededly had no personal experience with cocaine users, as distinguished from cocaine distributors. We discern no abuse of discretion.
United States v. Diaz,
Due to her DEA experience, Agent Kelleher was competent to testify to the relative raw-weight distinctions in the drug quantities typically possessed by users аs distinguished from dealers.
See, e.g., United States v. Valle,
D.The Sufficiency of the Evidence
Next, Reynoso contends that the government adduced no creditable evidence that he supplied the kilogram of cocaine found in Valera’s store. We review
de novo
all the evidence, as well as all credibility determinations, in the light most favorable to the verdict to determine
*50
whether a rational jury could have found the defendant guilty beyond a reasonable doubt.
United States v. Morillo,
Altogether aside from Reynoso’s confession, Valerа explicitly testified that Reynoso supplied the kilogram of cocaine seized at the store. Plainly, the mere fact that Valera cooperated with thе government, in return for a more lenient sentence, did not render his testimony unreliable,
per se.
Moreover, the jury was fully apprised of the plea agreement Valera еntered into with the government.
See United States v. Hernandez,
Similarly, Reynoso сontends that there was insufficient evidence that he intended to distribute the 110 grams of cocaine seized from his car. The jury heard the expert testimony given by Agent Kelleher, supra, as well as evidence that Reynoso supplied Valera with other cocaine plainly intended for distribution. In contrast, Reynoso presented the implausible dеfense that he needed to have as much as 110 grams on hand because his supplier was away on a six-week vacation.
E. The Obstruction of Justice Enhancement
Reynoso maintains that the district court еrred in imposing a two-level “obstruction of justice” enhancement under U.S.S.G. § 3C1.1, given that the government failed to establish that he perjured himself in testifying that he received no
Miranda
wаrnings and that he had intended the 110 grams of cocaine exclusively for his own use, whereas that testimony could have resulted simply from poor memory or the shock and confusion incident to his arrest. Questions of. law concerning interpretations of the Sentencing Guidelines are reviewed
de novo,
and the factual conclusions of the sentencing court, which must be supported by a preponderance of the evidence, are reviewed for clear error.
United States v. Damon,
Although false testimony caused by mistakе, confusion or poor memory is not perjurious,
see United States v. D’Andrea,
F. The Denial of the Motion to Depart Downward
Lastly, Reynoso maintains that the district court erred in denying a downward departure notwithstanding the fact that, as a deportable aliеn, he would not have the benefit of various ameliorative programs, such as a halfway house and a work release program, which would be available to comparable non-alien prisoners; hence, his conditions of imprisonment would be rendered more severe. Absent any evidence that the district court erronеously believed that it lacked the discretionary power to depart downward in these
*51
alleged factual circumstances,
see United States v. Farouil,
Affirmed.
Notes
. Even assuming that the August delay was nonexcludable, Rеynoso has advanced no argument on appeal as to why at least one day of the eighteen-day delay in empaneling the second jury, which occurrеd after the unprecedented terrorist attacks of September 11, 2001, would not have been fairly excludable under the STA's "ends of justice” exclusion.
See
18 U.S.C. § 3161(h)(8)(A);
United States v. Barnes,
. Absent any evidence of governmental misconduct, we likewise reject the claim that the trial delay violated Reynoso’s due process rights.
See, e.g., United States v. Stokes,
