Donald Gardner pled guilty to charges of possessing crack cocaine with the intent to distribute and of being a felon in possession of a firearm. The district court sentenced him to 210 months in prison followed by five years of supervised release. On appeal, Gardner argues that his guilty plea should be set aside because it was not made knowingly and voluntarily and because he was denied the effective assistance of counsel. He also contends that the district court erred in imposing a drug-quantity enhancement based upon nearly $16,000 found in Gardner’s pickup truck at the time of his arrest. Finally, Gardner argues that his sentence should be vacated in light of
United States v. Booker,
—U.S. -,
I. BACKGROUND
Gardner was arrested in October of 2002 after the police received a tip from a confidential informant that Gardner had been spotted with a large amount of cash and a quantity of crack cocaine in an area of Grand Rapids, Michigan known for heavy drug activity. In conjunction with Gardner’s arrest, the police seized from his pickup truck 45 grams of crack cocaine, $15,796 in cash (wrapped in bundles of $1,000 each), 2 cellular phones, a pager, and several slips of paper containing names and telephone numbers. A subsequent search of his apartment and garage uncovered an additional 27 grams of crack cocaine, a .44-caliber revolver, and 50 live rounds of ammunition.
The indictment charged Gardner with “knowingly, intentionally, and unlawfully possessing] with intent to distribute 50 grams or more of a mixture or substance containing cocaine base (crack cocaine),” in violation of 21 U.S.C. § 841(a)(1) and § 841 (b)(l)(A)(iii), and with being a felon in possession of a firearm, in violation of 18 U.S.C. § 922(g)(1) and § 924(a)(2). He pled guilty to both counts.
At Gardner’s sentencing hearing, the district court imposed an enhancement for possession of a dangerous weapon and a drug-quantity enhancement based upon the nearly $16,000 in cash found in Gardner’s pickup truck, which the court determined was the proceeds from selling 598.74 grams of crack cocaine. Gardner objected to the latter enhancement, claiming that the money was unrelated to his cocaine dealing. He instead maintained that the bulk of the cash was from the sale of furniture and audio equipment at his cousin’s nightclub, and the rest was from the sale of marijuana. The district court rejected Gardner’s explanation and sentenced him to 210 months of imprisonment, followed by five years of supervised release. Gardner timely appealed.
II. ANALYSIS
A. Standard of review
Because Gardner has waited until this appeal to first raise an issue regarding the district court’s alleged failure to comply with the requirements of Rule 11 of the Federal Rules of Criminal Procedure, the “plain error” standard of review is applicable.
See United States v. Vonn,
Gardner also claims that he was denied the effective assistance of counsel. We review such a claim de novo.
United States v. Wagner,
Finally, Gardner contends that he is entitled to be resentenced in light of
Booker,
— U.S. -,
*544 B. The district court did not err in accepting Gardner’s guilty plea
Gardner argues that his guilty plea was not made knowingly and voluntarily. He contends that his plea should be set aside because it was entered without a written plea agreement and with no “meaningful interaction” between Gardner and the district court.
To be valid, a guilty plea must be entered knowingly, voluntarily, and intelligently.
Brady v. United States,
requires that a district court verify that the defendant’s plea is voluntary and that the defendant understands his or her applicable constitutional rights, the nature of the crime charged, the consequences of the guilty plea, and the factual basis for concluding that the defendant committed the crime charged.
United States v. Webb,
Gardner contends that his plea colloquy did not satisfy the “core concerns” of Rule 11 as articulated in
United States v. DeBusk,
The fact that most of the questions posed by the district court to Gardner required only a yes-or-no answer does not, as Gardner asserts, render their exchange meaningless. As this court has previously noted,
[t]here is no requirement that in order to rely on a defendant’s answer in a guilty-plea colloquy to conclude that the defendant pleaded guilty knowingly and voluntarily, those answers must be lengthy and all-encompassing; a straightforward and simple “Yes, your Honor” is sufficient to bind a defendant to its consequences.
United States v. Walker,
We conclude that Gardner’s plea colloquy met the requirements established by Rule 11. Consequently, his plea was knowing, voluntary, and intelligent and should not be set aside.
See McCarthy,
*545
C. Gardner’s claim of ineffective assistance of counsel is not ripe for review
Gardner also argues that his right to the effective assistance of counsel was violated by his attorney’s failure to ensure that Gardner understood the nature and consequences of his guilty plea. Specifically, he claims that his attorney erred in failing to inform him that the government planned to assert that the nearly $16,000 found in Gardner’s pickup truck should be considered as the proceeds of crack cocaine sales for the purpose of calculating Gardner’s sentence.
A guilty plea can be involuntary as a result of the ineffective assistance of counsel.
See Hill v. Lockhart,
Here, the alleged ineffectiveness of Gardner’s counsel is not apparent. The record contains no evidence regarding what advice, if any, his counsel provided with regard to the potential drug-quantity enhancement. We therefore decline to address Gardner’s claims of ineffective assistance of counsel until the facts surrounding his attorney’s alleged misconduct can be more appropriately developed by the district court.
See Long,
D. The district court did not err in determining the amount of crack cocaine sold by Gardner for sentencing purposes
Gardner next contends that the district court erred in calculating his sentence by improperly considering the $15,796 found in his pickup truck at the time of his arrest as the proceeds of crack cocaine sales. He claims that the court’s conclusion was based upon “speculation or conjecture.” In reality, according to Gardner, $10,796 of this money was the result of the sale of furniture and audio equipment from his cousin’s nightclub and the remaining $5,000 came from the sale of marijuana.
*546
Where the quantity of drugs at issue cannot be easily determined, the district court may estimate the amount, but the “court must err on the side of caution.”
United States v. Walton,
In other cases, however, this court has “approve[d] the conversion of seized funds into an equivalent amount of drugs,” provided that the converted amount is supported by a preponderance of the evidence.
United States v. Samour,
Here, as in the above cases, there was sufficient evidence for the district court to approximate the quantity of crack cocaine sold by Gardner. Specifically, Gardner was observed late at night in a high-drug-traffic area sitting in a pickup truck not registered to him. The cash found in the vehicle was located in close proximity to the crack cocaine and was wrapped in bundles of $1,000 each, which is consistent with the manner in which drug dealers maintain their proceeds. A subsequent search of Gardner’s apartment found jars and cooking utensils covered with cocaine residue, as well as packaging materials and more crack cocaine. The district court reviewed the evidence and concluded that
if you just look at the ... presentence report, all the facts and circumstances in that report lead up to a rational conclusion by a preponderance of the evidence — circumstantial though it may be — that [Gardner] got that money by selling crack cocaine. There is no evidence — no evidence at all that he sold marijuana. The marijuana that was found in his apartment was use amount.
*547 And as far as the sale of the furniture and sound equipment at the nightclub goes, without evidence of that, as to the money coming from that sale, [Gardner’s] mere statement of it, it’s hard to believe.... [T]here are a lot of statements floating around out there, but where is the proof?
Given the weight of the evidence suggesting that the money found in Gardner’s pickup truck came from the sale of crack cocaine and the lack of any evidence to support Gardner’s claim that it was actually from the sale of other items, the district court’s calculation of the drug quantity was not clearly erroneous.
E. Gardner’s sentence should be remanded in light of Booker
Even though the district court did not err in considering the money found in Gardner’s pickup truck as proceeds from the sale of 598.74 grams of crack cocaine, we nevertheless vacate Gardner’s sentence and remand the case for resentencing in light of
Booker. See United States v. McDaniel,
III. CONCLUSION
For all of the reasons set forth above, we AFFIRM the judgment of the district court with respect to Gardner’s guilty plea and the court’s calculation of the drug quantity, but VACATE Gardner’s sentence and REMAND the case for resen-tencing in light of Booker.
