The appellants, mother and son, were convicted of various drug-related offenses and sentenced to lengthy prison terms. Both Verners were convicted of one count of possession of a controlled substance (cocaine base) with the intent to distribute, in violation of 21 U.S.C. §§ 841(a)(1), (b)(1)(a); 21 U.S.C. § 860(a) (distribution or manufacturing near a school); 18 U.S.C. § 2 (aiding and abetting); and of one count of maintaining a place for the purpose of manufacturing a controlled substance, in violation of 21 U.S.C. § 856(a)(1) (the “crack-house” statute). In addition, Laroan Verners was convicted of use of a firearm during and in relation to a federal drug trafficking crime, in violation of 18 U.S.C. § 924(c)(1). The Verners challenge the sufficiency of the evidence for all of these counts. (Although Mrs. Verners does nоt specifically challenge her conviction for aiding and abetting, she does challenge the underlying facts which support this conviction. In light of this ambiguity, we have addressed the sufficiency of the evidence for this conviction.) Mr. Verners also challenges the calculation of the amount of cocaine base used to determine his sentence under the Sentencing Guidelinеs. Finally, Mrs. Ver-ners contends that the district court abused its discretion in failing to grant her motion for a separate trial.
The government has demonstrated the following facts. On January 5, 1993, a team of law enforcement officers from the City of Tulsa, Oklahoma, executed a search warrant at the home of Guessinia Verners. Laroan Verners had used the house as his residence at onе time, still visited the house regularly, and still gave the address as his residence. He used his former bedroom in the house to store some of his possessions, although it appears that he did not sleep there. In the bedroom associated with Mr. Verners, police found digital scales, razor blades, cut (a substance used to dilute the purity of cocaine), large amounts of cash, two handguns — one loaded, one unloaded — and ammunition. No fingerprints were found on either gun. The police also found towels and baggies containing small amounts of cocaine in this bedroom. In the closet, some clothes, identified as be *294 ing similar or identical in appearance to clothes worn by Mr. Verners, were found; the bedroom also contained boxes of record albums belonging to Laroan Verners. The police also found some receipts and business records belonging to Mr. Verners, including a notebook alleged to be a drug ledger.
The other main items of evidence in this case were found in the kitchen. Inside the microwave were spatters which were tested and revealed to contain cocaine. In the cabinet a pyrex cuр was found containing a large “cookie” of cocaine base, or “crack” cocaine, weighing over 100 ounces. Boxes of baking soda and plastic baggies were also found. Taken as a whole, the evidence strongly indicated that powder cocaine was being converted in the microwave to cocaine base, then weighed and bagged for distribution. However, no evidence of an actual sale was introduced. In fact, the only other evidence of involvement with drugs by either Laroan or Guessinia Verners were statements (overheard by the police) that were made at the time of the search by Mrs. Verners to her daughters. After being informed that cocaine had been found in the microwave and that she should consider сonsulting an attorney, Mrs. Verners was overheard to say, “The phone rang just before they found the stuff in the microwave. They got a phone call. Who knew about that besides us?”, or words to that effect. She also apparently asked her daughters to whom they might have talked who could have tipped off the police.
“In determining the sufficiency of the evidence, we review the rеcord de novo, ... and ask only whether, taking the evidence— both direct and circumstantial, together with the reasonable inferences to be drawn therefrom — in the light most favorable to the government, a reasonable jury could find the defendant guilty beyond a reasonable doubt.”
United States v. Urena,
Viewing the evidence in the light most favorable to the prosеcution, a reasonable jury could find that Laroan Verners possessed cocaine with the intent to distribute it. In order to support a conviction for possession with intent, the government must prove knowing possession of a controlled substance, with intent to distribute. Possession need not be actual, but may be constructive.
United States v. Culpepper,
The government also provided sufficient evidence of Laroan Verners’s intent to distribute. One of the investigating officers testified that the amount of cocaine recovered was in excess of an amount which might be possessed for personal use. (In fact, the amount was estimated to be equivalent to 2,000 dosage units.) Coupled with the presence of scales, razor blades, cut, guns and ammunition, large amounts of cash, and the noteboоk in Laroan Verners’s bedroom, the large amount of cocaine and the baggies found in the kitchen provided ample evidence for a jury to conclude that Mr. Verners was involved in the distribution of drugs.
The case against Guessinia Verners for possession witjh intent to distribute is far weaker and presents a close question. Although there is ample evidence that she had knowledge of the presence of the drugs in the kitchen and sufficient evidence to show constructive possession of these drugs, there is little, if any,- evidence of her intent to distribute. The government did not, for ex *295 ample, offer any evidence that she actively participated in either the manufacture or distribution of the drugs.
The government suggests that her statements evidenced her intent to distribute. By showing knowledge of the “stuff’ in the kitchen, the statements do tend to show acquiescence in the drug activities. However, on their own, the statements do not evince an intent to distribute. The government bolstered this theory with evidence that Mrs. Verners knowingly benefitted from the drug operation. For example, the government introduced testimony that the Verners’ home contained some nice furnishings. The governmеnt also established that she was paying substantial amounts of cash for an addition to the home that was being constructed. Although the government did not prove that the money to pay for these improvements was derived from drug sales, Mrs. Verners was not employed at the time and no alternative source of income was identified.
This evidence is simply insufficient to support a conviction for possession with intent to distribute. 1 At best, this evidence shows that she had the intent to aid and abet her son.
To be guilty of aiding and abetting a crime, the defendant must willfully associate h[er-]self with the criminal venture and seek to make it succeed through some action on [her] part. The government must prove more than mere presence at the scene of the crime even if coupled with knowledge that the crime is being committed. However, participation may be established by circumstantial evidence, and the evidence may be of “relatively slight moment.”
United States v. Esparsen,
On the charge of maintaining a residence for the purpose of manufacturing drugs under the sо-called “crack-house statute,” 21 U.S.C. § 856(a)(1), the evidence is sufficient only to convict Laroan Verners. Section 856(a)(1) makes it unlawful to “knowingly open or maintain any place for the purpose of manufacturing, distributing, or using any controlled substance.” This circuit has rarely addressed this statute. In
United States v. Williams,
The first such term is “maintain.” In
United States v. Williams,
we found that,
*296
where the “place” in question is a residence, the defendant must have a “substantial connection” to the home and must be more than a “casual visitor” in order to satisfy this element.
Acts evidencing such matters as control, duration, acquisition of the site, renting or furnishing the site, repairing the site, supervising, protecting, supplying the food to those at the site, and continuity are, of course, evidence of knowingly maintaining the place considered alone or in combination with еvidence of distributing from that place.
United States v. Clavis,
Larоan Verners also exercised dominion and control over the house, or at least over his bedroom. He had lived there and continued to use the bedroom to store many of his personal belongings and business-related items. He had a key to the house and came and went as he pleased. He was far from a casual visitor. His actions also fit within the meaning of the word “maintаin.”
The more complex question is whether, as the government contends, La-roan and Guessinia Verners maintained this residence “for the purpose of’ manufacturing cocaine base. While we have yet to address this issue, our fellow circuits have examined in this context the contours of the term “for the purpose of.” In
United States v. Chen,
The Seventh Circuit has drawn upon a business analogy to interpret the term “for the purpose of’ within the context of § 856(a)(1). In the recent case of
United States v. Banks,
Under either of these tests, the government has provided sufficient evidence against Laroan Verners and insufficient evidence against Guessinia Verners. Because Mr. Verners was apparently not sleeping at the house, it appears that one of his primary purposes in maintaining his place in the home was as a base of operations to run a drug manufacturing and distributing business. The vast majority of the equipment, records, and money associated with the drug enterprise were found in the room which was under his control, indicating that he was the “manager” of the enterprise.
In contrast, there is no evidence that Gues-sinia Verners occupied more than a minor role in the home-based drug business of her son. That is not to say that she may not, in fact, have actively taken part in the business. We find, however, that the evidence presented supports the conclusion that her primary purpose in maintaining the house was as a home for herself and her two daughters. There is no evidence that she used Laroan Verners’s bedroom or was aware of its contents. There is no evidence that she “managed” or “supervised” her son’s business. No rational jury could conclude beyond a reasonable doubt that she had the requisite mental purpose for conviction under this statute. 4
The government has provided barely sufficient evidence to convict Laroan Verners of the use of a gun in relation to a drug offense. To prove a violation of 18 U.S.C. § 924(c), the government must demonstrate that the defendant “use[d]” or “carrie[d]” a firearm “during and in relation to” a drug trafficking crime.
United States v. Nicholson,
The government concedes that La-roan Verners did not actually use (in the sense of fire or brandish) or physically carry the guns in this case, but argues that the proximity of the guns to the money and drug paraphernalia satisfies the “ready access” test set forth in
United States v. McKinnell,
The district court did not abuse its discretion in fading to grant Mrs. Ver-ners’s motion for a separate trial.
United States v. Hayes,
The district court’s calculations of the amount of cocaine involved for the purposes of determining the appropriate sentencing guideline are not clearly erroneous. The government showed by a preponderance
*298
of the evidence that Laroan Vеrners’s notations were records of drug sales. The court’s calculations based on these notes and the amount of cash found, plus the actual drugs recovered, are also supported by a preponderance of the evidence.
United States v. Cody,
Laroan Verners’s convictions for possession with intent to distribute, maintaining а place for the purpose of manufacturing cocaine, and use of a gun in the course of a drug trafficking crime are AFFIRMED, except that his conviction for aiding and abetting is REVERSED. We AFFIRM the district court’s calculations of the amount of cocaine for sentencing guideline purposes.
Guessinia Verners’s convictions for possession with intent to distribute, committing a drug offense neаr a school, and maintaining a place for the purpose of manufacturing cocaine are REVERSED. Her conviction for aiding and abetting possession with intent to distribute is AFFIRMED.
Accordingly, these cases are REMANDED for resentencing consistent with this opinion.
Notes
. Because we are overturning this conviction, we must necessarily reverse Mrs. Vemers's conviction under 21 U.S.C. § 860(a) as well. This section, which рenalizes the commission of a drug offense within 1,000 feet of a school, is essentially a sentence enhancement provision for the principal drug offense.
. Since we find that Mrs. Verners is not guilty of the underlying crime, it is apparent that Laroan Verners cannot be convicted of aiding and abetting her. One cannot aid and abet an aider and abetter, nor can one aid and abet oneself.
See United States v. Teffera,
.This statute has survived at least three challenges for being unconstitutionаlly vague.
See United States v. Lancaster,
. Congress did intend to punish those who knowingly allow others to use their properly to run drug operations. However, this intent is expressed in 21 U.S.C. § 856(a)(2), not (a)(1). We do not mean to second-guess the prosecutor’s judgment, but merely suggest that Mrs. Verners might have been more easily convicted under 856(a)(2), which prohibits those who "control any building, room, or enclosure” from “mak[ing] available for use, with or without compensation, the building, room, or enclosure for the purpose of unlawfully manufacturing, storing, distributing, or using a controlled substance.” On the difference between 856(a)(1) and (a)(2),
