This appeal requires us to review the imposition of a mandatory minimum sentence where the district court has found sentencing entrapment.
Ramon Montes Castaneda timely appeals his conviction and sentence for conspiracy to distribute cocaine and possession of cocaine with intent to distribute. We have jurisdiction, 28 U.S.C. § 1291, and we vacate the sentence and remand for resentencing. We affirm Castaneda’s conviction.
I
Working with Agent Robert Kursar of the Drug Enforcement Agency (“DEA”), confidential informants Richard Orestad and Darrell Beck initiated purchases of cocaine through Theresa Sullivan, who lived with Or-estad and Beck. Until her arrest, Sullivan did not know that Kursar was a DEA agent.
According to Sullivan’s trial testimony, Castaneda supplied her with cocaine on numerous occasions. Sullivan and Orestad testified that, after one failed transaction, Castaneda agreed to provide them with one kilogram of cocaine. Orestad testified that he went to Castaneda’s residence, where he met Castaneda, Graciela Becerra and Jose Abel Ramirez. Castaneda opened Becerra’s purse and showed Orestad one kilogram of cocaine inside.
According to Orestad, he told Castaneda to meet him at his house to complete the transaction and then informed Agent Kursar. After Castaneda, Ramirez and Becerra arrived at Orestad and Sullivan’s residence, Orestad left to meet Kursar, who was posing as a buyer for a wealthy Canadian. Kursar then telephoned Sullivan and told her that the deal was off. Sullivan tried to persuade Kur-sar to complete the transaction, stating that Orestad had given Castaneda title to Ores-tad’s truck as collateral. Kursar refused.
Shortly thereafter, police watching Sullivan’s residence saw Castaneda, Sullivan, Ramirez and Becerra depart in Castaneda’s vehicle. Marked police cars attempted to stop *594 Castaneda. During a two-mile chase, the purse containing the cocaine was thrown from Castaneda’s vehicle. When the vehicle was stopped, police arrested Castaneda and found a fictitious title to Orestad’s truck. A passerby found the purse and brought it to the police.
At trial, the defense claimed that Orestad had framed Castaneda and his friends by luring them to his residence with the promise of a favorable deal on his truck. The jury found Castaneda guilty of conspiracy to distribute and possession with intent to distribute cocaine.
At the sentencing hearing, the court found that sentencing entrapment had occurred, and the government did not oppose a downward departure from the applicable sentencing guideline range based upon sentencing entrapment. 1 The district court attributed one kilogram of cocaine to Castaneda and imposed the five year statutory minimum sentence pursuant to 21 U.S.C. § 841(b)(l)(B)(ii). The court said that it lacked discretion to sentence Castaneda to a term below the statutory minimum. Castaneda timely appealed.
After filing his appeal, Castaneda learned that Orestad had been indicted for his role in a cocaine conspiracy occurring after and perhaps during his trial testimony. Arguing that the government’s case rested on Ores-tad’s credibility, Castaneda moved for a new trial and for a stay of the appeal. We denied the stay, and the district court later denied the motion for a new trial.
II
We review
de novo
a district court’s construction of a statute requiring the imposition of minimum sentences.
United States v. Vilchez,
Minimum penalties for violations of 21 U.S.C. § 841(a) not involving the specific enhancements of 21 U.S.C. § 859, 860 or 861 are set out in 21 U.S.C. § 841(b)(1). Under section 841(b)(l)(B)(ii), a violation involving more than 500 grams of cocaine carries a mandatory five year minimum sentence. For violations involving less than 500 grams of cocaine, no statutory minimum applies. 21 U.S.C. § 841(b)(1)(C).
District courts do not have the authority to impose a sentence below a statutory minimum absent a motion by the government pursuant to 18 U.S.C. § 3553(e) based upon a defendant’s substantial assistance.
United States v. Valente,
The quantity of drugs involved in a violation establishes the applicable statutory minimum. District courts determine the quantity of drugs involved in a violation at sentencing.
United States v. Harrison-Philpot,
At sentencing, counsel for Castaneda urged the district court to reduce the amount of cocaine attributable to Castaneda by subtracting the amount tainted by sentencing entrapment. “Sentencing entrapment or sentence factor manipulation occurs when a defendant, although predisposed to commit a minor or lesser offense, is entrapped in committing a greater offense subject to greater punishment.”
United States v. Staufer,
In
United States v. Naranjo,
The government’s briefs failed to address
Naranjo.
Although the government might have argued that in
Naranjo
we did not actually endorse the district court’s reduction of the attributable drug amount, this argument would fail, because Naranjo had received the statutory minimum term.
Naranjo,
The district court here did not think that it had the discretion to reduce the amount of cocaine attributable to Castaneda by the amount tainted by sentencing entrapment. Otherwise, the court might have found, for example, that Castaneda lacked the predisposition to sell 500 grams or more of cocaine. Had the district court made such a finding, it could have excluded more than 500 grams from its finding of cocaine attributable to Castaneda. A finding that less than 500 grams of cocaine were attributable to Castaneda would result in no obligation to impose a statutory minimum sentence.
We vacate the sentence and remand for resentencing. We express no opinion on the merits of Castaneda’s claim of sentencing entrapment or the precise quantity of cocaine that Castaneda was predisposed to distribute.
Castaneda also argues that the district court’s denial of his motion for a new trial foreclosed his opportunity to further develop his sentencing entrapment theory. On remand, the district court can determine whether to address Castaneda’s new evidence.
Ill
Castaneda challenges the district court’s exclusion of his cultural expert’s testimony. A district court’s decision to admit expert opinion testimony is reviewed for abuse of discretion.
United States v. Von Willie,
Federal Rule of Evidence 702 allows the admission of expert testimony where it will assist the jury in understanding the evidence or determining a fact in issue. Jurors will only be assisted by: (1) a qualified expert (2) testifying about a proper subject (3) in conformity with a generally accepted explanatory theory (4) with more probative value than prejudicial effect.
United States v. Rahm,
Castaneda sought to introduce the testimony of Ray Candía, a person familiar with problems faced by migrant farmworkers. Castaneda hoped to use Candia’s testimony to explain his flight from police, which weak *596 ened the defense theory that Orestad had lured Castaneda to his residence with the promise of a good deal on a truck. The district court allowed Candía to testify that Castaneda was an illegal alien who feared government authority and deportation.
We have previously held that a district court’s refusal to admit evidence from a cultural expert does not constitute an abuse of discretion.
United States v. Rubio-Villareal,
The district court did not abuse its discretion in excluding the expert testimony.
IV
Castaneda argues that the district court erred by rejecting his proposed instruction stating that the jury should draw no “adverse inference” from his failure to testify. We review
de novo
whether the jury instructions given adequately covered the defense theory when the district court has rejected a proposed instruction.
United States v. Gomez-Osorio,
Although a defendant has a constitutional right to a jury instruction that “minimize[s] the danger that the jury will give evidentiary weight to a defendant’s failure to testify,”
Carter v. Kentucky,
The district court gave instruction 3.02 from the Manual of Model Criminal Jury Instructions for the Ninth Circuit (1992 Edition). Instruction 3.02 states that it is the government’s burden to prove a defendant’s guilt beyond a reasonable doubt and that “[t]he defendant is presumed to be innocent and does not have to testify or present any evidence -to prove innocence.”
We recognize that the instruction did not contain the specific words “no inference,” which are preferable but not required under
Carter.
However, the instruction sufficiently covered the substance of Castaneda’s proposed instruction: the defendant’s failure to testify does not lessen the government’s burden to prove its case. Furthermore, in light of the compelling evidence against Castaneda, the district court rendered the error harmless by telling the jury during voir dire that “an accused cannot be compelled to testify, and if he exercises that right, you cannot allow that to affect your determination of the issues.... ”
See United States v. Hasting,
The district court did not commit reversible error by rejecting Castaneda’s proposed instruction.
V
We vacate Castaneda’s sentence and remand for resentencing. We affirm the conviction.
AFFIRMED in part, VACATED in part and REMANDED.
Notes
. The government’s failure to object at the hearing to the district court’s finding of sentencing entrapment forecloses its argument on appeal that Castaneda failed to prove sentencing entrapment.
. The district court may:
deduct the amount of cocaine attributable to the government's sentencing entrapment conduct, and calculate the sentence based on only the remaining amount of cocaine.... [This approach] would bring Naranjo within the five-year statutory minimum sentence ... rather than the ten-year statutory minimum....
