OPINION
This is a direct appeal of two related drug-trafficking cases. Pursuant to a jury trial, Defendants-Appellants Jason Hines and Kelly Edwards were convicted of conspiracy to distribute 500 grams or more of methamphetamine. On appeal, Hines and Edwards claim various trial errors. Hines also seeks vacation of his sentence under
Blakely v. Washington,
542 U.S.-,
I.
Jason Hines and Kelly Edwards were central participants in one of the largest drug trafficking organizations in Tennessee. Hines and another co-conspirator, James “Red” Fowler, were the primary contact with Mexican sources of methamphetamine and cocaine in Eastern Tennessee. Hines supplied Fowler with methamphetamine for over two years, until Fowler began developing his own Mexican sources. Hines and Fowler trafficked in large amounts of methamphetamine and cocaine. Testimony establishes that Hines and Fowler purchased as much as 10 to 20 pounds of methamphetamine at a time, and one kilogram of powdered cocaine. Hines and Fowler disbursed these large amounts of drugs quickly, selling at least several *715 pounds of methamphetamine in a month. The amounts of money involved were similarly large: testimony establishes that Fowler would typically pay Hines $30,000 at one time for the purchase of drugs.
After procuring large amounts of drugs from the Mexican sources, Hines and Fowler would then sell smaller lots to other drug dealers. For example, Kelly Horton, a drug dealer in Cleveland, Tennessee, typically would purchase a pound of methamphetamine from Fowler, for $9,500, and then sell individual ounce bags for' $1,400. At another time, Horton purchased four ounces from Hines. Gary Jenkins, a drug dealer in Chattanooga, Tennessee, purchased large amounts of methamphetamine and cocaine from both Fowler and Hines. Jenkins purchased two to four pound lots of methamphetamine and a kilogram of cocaine from Fowler, and similar amounts from Hines. Jenkins would then distribute the methamphetamine to street dealers who worked for him in Chattanooga. Jenkins also purchased a hunting rifle from Hines.
Kelly Edwards was employed by Red Fowler in the drug operation. Edwards worked on cars in a garage owned by Fowler, which was located, on Fowler’s property. Edwards assisted Fowler in hiding, delivering, and selling the methamphetamine. Edwards also purchased methamphetamine directly from the Mexican sources.
Eventually, federal and state agents broke the back of the conspiracy, resulting in about a dozen arrests, beginning with Red Fowler. Hines and Edwards were indicted several months later for conspiracy to distribute more than 500 grams of methamphetamine in violation of 21 U.S.C. § 846 (conspiracy), and § 841(á)(l) and (b)(1)(A) (drug trafficking).' Most of the co-conspirators agreed to plead guilty, including Fowler, but Hines and Edwards elected to exercise their right to a jury trial. At trial, 14 co-conspirators, including Fowler, testified as to Hines’s and Edwards’s involvement in the conspiracy. Several officers also testified as to their involvement. There was little or no physical evidence at trial; the evidence largely involved the testimony of co-conspirators and arresting officers. The jury convicted both Hines and Edwards.
After trial, Hines filed a motion for a new trial and motion for judgment of acquittal, and Edwards filed a motion for a new trial. The district court denied these motions.
At sentencing, the district judge determined that Hines had possessed approximately 32 pounds of methamphetamine during the course of conspiracy. The district judge also determined that Hines was subject to a firearm enhancement. Accordingly, Hines was sentenced to 235 months of incarceration and five years of supervised release. Edwards was sentenced to the statutory minimum — 120 months incarceration and five years supervised release.
Defendants-Appellants appeal their convictions and sentences, arguing various trial and. sentencing errors. After briefing was concluded,
Blakely v. Washington,
542 U.S.-,
II.
Edwards seeks reversal of his conviction on the basis of the following alleged trial errors: (1) that the district , court improperly restricted cross-examination of a Gov *716 ernment witness; (2) that the Government improperly commented on his failure to testify; (3) that the jury instructions for the conspiracy count were erroneous; and (4) that the cumulative effect of these errors resulted in an unfair trial.
A. Cross-Examination under Fed. R.Evid. 609
At trial, defense counsel attempted to cross-examine Fowler regarding his pri- or felony convictions. Edwards argues the district court limited the scope of cross-examination, apparently in response to an objection by the prosecution. The short colloquy is as follows:
Q. [Mitchell Bryant, defense counsel]. Mr. Fowler, you have prior felony convictions, don’t you, sir?
A. [Fowler]. When, I was young, 17 years old.
Q. Not as an adult?
A. No other felony convictions, no.
Q. Okay. Burglary, Whitfield County, 1987?
A. Seventeen.
Q. You were 17 then?
A. Yeah. Sentenced under the Youthful Offender Act.
Q. Okay. Some charge called criminal interference with government that you got 12 months for?
Mr. Piper [AUSA]. Objection, Your Honor, if Mr. Bryant is going to read from the NCIC I would respectfully request that he at least be aware it’s A; it’s either a crime of falsehood or dishonesty or B; it’s proper impeachment with a felony within the previous 10 years. Obviously, Mr. Fowler is not trying to hide anything with respect to this, but I don’t believe Mr. Bryant is allowed to go on a fishing expedition with respect to cross-examination.
Mr. Bryant. Your Honor, I’m looking at the information that was provided to me by the government from pre-trial services. I’m trying to figure out what are felonies and what are not. There are three pages of them here.
Mr. Piper. Judge I object to that, and Mr. Bryant knows better than that.
And I can—
The Court. Why don’t you move on to another subject, Mr. Bryant.
Mr. Bryant. Sir?
The Court. Just move on to another subject.
Mr. Bryant. Yes, sir.
A district court’s limitation of cross-examination is reviewed for an abuse of discretion.
See United States v. Green,
Given these standards, there was no error. As an initial matter, the district court did not specifically limit the cross-examination of Fowler. Rather, based on a suggestion from the Court, defense counsel apparently self-regulated his questioning regarding Fowler’s prior felony conviction. Under such circumstances, it is unclear if the district court exercised its discretion in limiting the testimony.
Even if we accept that the district court limited the cross-examination, there was still no error. Testimony by Fowler establishes that his only prior felony conviction *717 was as a juvenile, the evidence of which is generally inadmissible. This was noted in open court before the jury, and there was no apparent limiting instruction; accordingly, the jury had at least some evidence of Fowler’s felony criminal history. To the extent that evidence of other, unmentioned convictions was excluded, no evidence establishes that such convictions are admissible under Rule 609. Accordingly, this argument cannot support reversal.
B. Comments on Failure to Testify
During the testimony of Detective Patrick Cook, the Government noted that Kelly Horton did not testify in his own defense in a prior unrelated case in which he had been acquitted. Defense counsel did not object to this comment. The relevant section of the testimony is as follows:
Q. And what was the item?
A. It was a package containing about two ounces of what tested out to be methamphetamine.
Q. And Mr. Horton went to trial on this?
A. Yes sir, he did.
Q. And was he convicted or acquitted?
A. No, sir, he was acquitted on it.
Q. On the methamphetamine?
A. Yes, sir.
Q. He didn’t take the stand at the trial?
A. No, sir, he did not.
The prosecution apparently made no other comments regarding any other witness’s failure to testify.
The admission of unchallenged testimony is reviewed for plain error. Fed.R.Crim. P. 52(b);
United States v. Kelly,
Here, the Government’s comment on the failure to testify in an unrelated trial is directed towards Kelly Horton, a co-conspirator witness, and not the accused. No evidence indicates that the Government intended the comment as a statement concerning Edwards’s lack of testimony. Nor does the single, short comment from the Government appear to be connected to the instant case.
In any event, even if the comment could be imputed against Edwards, admission of the evidence must still be plainly erroneous. Under the third element of a plain error analysis, the error must be prejudicial such that it has a substantial effect on the rights of the accused.
Rogers,
*718 C. Jury Instructions as to Conspiracy
Edwards also argues that the jury instructions for conspiracy were so erroneous as to require a new trial. The relevant portion of the district court’s jury charge regarding conspiracy is as follows:
A conspiracy is a kind of criminal partnership. For you to find the defendants guilty of the conspiracy charge, the government must prove both of the following elements beyond a reasonable doubt:
First, that two or more persons conspired, or agreed, to commit the crime of distributing methamphetamine.
Second, that the defendants knowingly and voluntarily joined the conspiracy....
With regard to the first element — a criminal agreement — ’the government must prove that two or more persons conspired, or agreed, to cooperate with each other to commit the crime of distributing methamphetamine....
If you are convinced that there was a criminal agreement, then you must decide whether the government has proved that the defendants knowingly and voluntarily joined that agreement.
This does not require proof that the defendants knew everything about the conspiracy, or everyone else involved, or that they were a member of it from the very beginning. Nor does it require proof that the defendants played a major role in the conspiracy, or that their connection to it was substantial. A slight role or connection may be enough.
But proof that the defendants simply knew about a conspiracy, or were present at times, or associated with members of the group, is not enough, even if they approved of what was happening or did not object to it....
What the government must prove is that the defendants knew the conspiracy’s main purpose, and that they voluntarily joined it intending to help achieve or advance its goals, this is essential.
Since defendants did not object to the jury charge at trial, we review for plain error.
United States v. Morrow,
Here, the instructions on conspiracy were not plainly erroneous. The district court’s instructions essentially tracked the language and organization of the Sixth Circuit Pattern Jury Instruction regarding conspiracy.
See
Sixth CIRCUIT PatteRN Jury Instructions §§ 3.01(A)-3.04. The district court properly omitted the element requiring an overt act in furtherance of the conspiracy, since an overt act is not required for the purposes of 21 U.S.C. § 846.
United States v. Shabani,
We recognize that the elements of a § 846 conspiracy are: “(1) an agreement to violate drug laws, (2) knowledge and intent to join the conspiracy, and (3) participation in the conspiracy.”
United States v. Gibbs,
This holding is buttressed by the overwhelming evidence that Edwards was an essential participant in the conspiracy. Fourteen co-conspirators testified that Edwards was an employee of Fowler, and
*719
participated in the procurement, storage and delivery of large amounts of methamphetamine. Given this evidence, the error did not affect the “substantial rights of the accused,” or the “fairness, integrity or public reputation of judicial proceedings.”
Rogers,
D. Cumulative Effect
Edwards also argues that the cumulative effect of these errors support a new trial, even if individually such errors do not warrant reversal. Edwards notes that the cumulative effect of individual errors may result in a trial setting that is fundamentally unfair.
See Walker v. Engle,
While in some situations cumulative error might be enough to support reversal, this is not such a case. As noted above, the district court’s limitation of Fowler’s cross-examination and the Government’s comments on Horton’s failure to testify cannot be considered evidentiary error. Accordingly, the only arguable error by the district court was the failure to include the participation element in the jury charge for conspiracy. For the aforementioned reasons, this error is insufficient to support reversal.
III.
On appeal, Hines seeks reversal of his conviction and a new sentencing, arguing that: (1) there was insufficient proof to support the conviction; and (2) the district court erred in determining the amount of drugs and the imposition of a firearm enhancement. In supplemental briefing, Hines also argued that his sentence violated the Sixth Amendment under Blakely and Booker.
A. Sufficiency of the Evidence
Hines argues that the district court erred in denying his motion for judgment of acquittal or a new trial, since the evidence was insufficient to support his conviction. Hines notes that no drugs or firearms were found in his possession at -the time of the arrest. Hines further notes that evidence of drug trafficking activity at trial consisted solely of the testimony of eo-eonspirators, all of whom had received favorable treatment from the Government based on their plea agreements, or promises to cooperate.
We review a motion for judgment of acquittal
de novo,
examining “whether after viewing the evidence in the light most favorable to the prosecution,
any
rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.”
Jackson v. Virginia,
Here, the district court’s denial of a motion for acquittal or new trial is not error. Circumstantial and testimonial evidence are sufficient to support a jury finding of conspiracy.
See United States v. Price,
B. Sentencing Enhancements and Booker
Hines also appeals the district court’s findings that he was responsible for approximately 32 pounds of methamphetamine pursuant to U.S.S.G. § 2Dl.l(e), and that he had used a firearm in connection with the drug crime pursuant to U.S.S.G. § 2Dl.l(b).
Prior to
Booker,
we reviewed for clear error a district court’s factual findings regarding the amount of drugs attributable to the defendant or whether he possessed a firearm.
United States v. Bartholomew,
Although the district court’s factual findings are supported by the record, Hines is nonetheless entitled to re-sentencing under
Booker.
In
Booker,
the Supreme Court held that under the Sixth Amendment “[a]ny fact (other than a prior conviction) which is necessary to support a sentence exceeding the maximum authorized by the facts established by a plea of guilty or a jury verdict must be admitted by the defendant or proved to a jury beyond a reasonable doubt.”
Booker,
Significant guidance as to Hines’s sentence may be found under the facts of
Booker.
In
Booker,
the jury found the defendant had possessed 92.5 grams of crack cocaine.
Id.,
The Supreme Court affirmed the Seventh Circuit. In particular, the Supreme Court noted:
In respondent Booker’s case, the District Court applied the Guidelines as written and imposed a sentence higher than the maximum authorized solely by the jury’s verdict. The Court of Appeals held Blakely applicable to the Guidelines, concluded that Booker’s sentence violated the Sixth Amendment, vacated the judgement of the District Court, and remanded for new sentencing. We affirm the judgment of the *721 Court of Appeals and remand the case. On remand, the District Court should impose a sentence in accordance with today’s opinions, and, if the sentence comes before the Court of Appeals for review, the Court of Appeals should apply the review standards set forth in this opinion.
Id.,
There is no meaningful distinction between Hines’s sentence and Booker’s sentence, at least for the purposes of the Sixth Amendment. Based on the indictment and the jury verdict form, the jury found that Hines had possessed more than 500 grams of methamphetamine. However, at sentencing, the trial judge found that Hines had possessed approximately 32 pounds of methamphetamine. Though substantial evidence supports the district court’s finding, that conclusion occurred under the prior sentencing regime. The same analysis also applies to the district court’s firearms enhancement.
The Government argues that re-sentencing under
Booker
is inappropriate since Hines “never argued that the Guidelines or the procedures used to determine Guidelines factors are unconstitutional under
Apprendi [v. New Jersey,
Since, however, Hines raised no
Ap-prendi,
Fifth Amendment, or Sixth Amendment claims in district court, the Government correctly notes that Hines must hurdle the requirements of plain error.
See also id.
(noting that though the defendant preserved the
Blakely
issue with the filing of a supplemental letter brief shortly after the issuance of that opinion, plain error is still the correct review given that no such claims were made in the district court);
United States v. Hughes,
The Government argues that there was no plain error since Hines’s substantial rights were not affected by the district court’s factual findings, and there was therefore no prejudice.
See Rogers,
This argument ignores the impact and applicability of
Booker.
As an initial matter, the fact that the jury heard such evidence is immaterial. The only factual finding by the jury memorialized in the record indicates that Hines possessed 500 grams or more of methamphetamine. “It is not the province of this Court to divine the jury’s interpretation of the evidence. ...”
S.E.C. v. Yun,
In any event, the Government’s view of an effect on the substantial rights of Hines is unduly limited. As noted by the remedial majority,
Booker
returns substantial discretion to the sentencing judge to depart above and below the Guidelines range, so long as such sentences are reasonable.
Id.
at 767 (Breyer, J., for the Court) (“The district courts, while not bound to apply the Guidelines, must consult those Guidelines and take them into account when sentencing”);
id.
at 766 (noting that a Court of Appeals should review
post-Booker
sentences for “reasonableness”). Remand is the only appropriate way, in this case, to allow the parties to argue for the exercise of the district court’s discretion as authorized by
Booker. Id.
at 769 (Breyer, J., for the Court) (remanding Fanfan’s case despite the fact that his sentence did not violate the Sixth Amendment, in order to allow the Government' the opportunity to seek a higher sentence);
Hughes,
IV.
For the foregoing reasons, we AFFIRM the conviction and sentence of Kelly Edwards in all respects; AFFIRM the conviction of Jason Hines in all respects; and VACATE and REMAND the sentence of Jason Hines for proceedings consistent with this opinion and United States v. Booker, supra.
