Armando Grimaldo and Julio Escobedo-Romero appeal' their convictions for conduct related to a drug distribution conspiracy headed by Jose Grimaldo-Zamorron, Grimaldo’s brother. Grimaldo was convicted of conspiracy to distribute methamphetamine and two counts of distribution of methamphetamine and sentenced to 120 months in prison. Escobedo-Romero was convicted of conspiracy to distribute methamphetamine and possession of cocaine with intent to distribute and sentenced to 70 months in prison. Escobedo-Romero argues that there was insufficient evidence to convict him on both counts. Both he and Grimaldo argue that there was no probable cause to search Grimaldo’s apartment. They also contend that the district court

erred in admitting certain evidence and in its findings of drug quantity attrib
*970
utable to them. Finally, Escobedo-Rome-ro and Grimaldo argue that in light of the Supreme Court’s decision in
Jones v. United States,
I.
In March 1998, a confidential informant met with Grimaldo-Zamorron and his girlfriend, Dina Rivas, in apartment 714 at the Tallcorn Towers in Marshalltown, Iowa to arrange a methamphetamine purchase. Pursuant to the arrangement, Jon Neus-chwanger, an undercover agent who was a member of the Mid-Iowa Drug Task Force, purchased a quarter pound of amphetamine 2 from Rivas in a car next to the Tallcorn. Rivas regularly assisted Grimal-do-Zamorron in his illegal activities by delivering methamphetamine and setting up deals. She and Grimaldo-Zamorron lived with Escobedo-Romero in apartment 714 during the month of March, and Gri-maldo-Zamorron stored methamphetamine there and sold it from the apartment. Grimaldo was out of the country at the time.
In June 1998, Segar Brown was arrested for possession of methamphetamine. Following his arrest, he agreed to cooperate in the investigation of Grimaldo-Zamor-roris drug activities. Rivas and Grimaldo-Zamorron had moved into the Flamingo Motel, and Grimaldo had returned from Mexico and was staying with Escobedo-Romero in apartment 714 at the Tallcorn. On June 8, Brown went to the Flamingo and paid Grimaldo-Zamorron $300 for a previous purchase. Later that day, after finding no one at the Tallcorn, Brown returned to the Flamingo and Grimaldo-Zamorron told him to “go back to the Tallcorn and talk to Julio and Armando.” Brown then acquired a half-ounce of methamphetamine from Grimaldo in apartment 714. Escobedo-Romero was present during the transaction.
Three days later, Brown went back to apartment 714, paid $400 to Grimaldo-Zamorron for the half-ounce, and asked for another ounce. Grimaldo and Escobedo-Romero were present. The next day, June 12, Brown and Darius Carr were sent to apartment 714 to get the ounce of methamphetamine. 3 According to Brown, no one was there; Carr testified that Grimal-do was present. They then went to the Flamingo, where Grimaldo-Zamorron wrote a note in Spanish and told them to give it to Grimaldo. They returned to the Tallcorn, gave the note to Grimaldo, and received an ounce of methamphetamine.
On June 15, Brown and Neuschwanger negotiated with Grimaldo-Zamorron outside a restaurant for the purchase of a quarter-pound of methamphetamine. Gri-maldo-Zamorron went to the Tallcorn, then to the Flamingo. Brown and Neus-chwanger met him at the Flamingo and obtained the quarter-pound, giving Grimal-do-Zamorron a partial payment of $900. Two days later, Neuschwanger paid Gri-maldo-Zamorron the $2100 that was still owed, and Grimaldo-Zamorron gave him an additional two ounces. On June 19, when Neuschwanger went to the Flamingo to pay for the two ounces, Grimaldo-Za-morron accepted the payment and fronted him a half-pound of methamphetamine.
The investigation culminated on June 25. Neuschwanger met Grimaldo-Zamor-ron at the Flamingo. They agreed that Neuschwanger could return in an hour to pick up a pound of methamphetamine. Both men left the hotel, and Grimaldo-Za-morron went to the Tallcorn. After Neuschwanger and Grimaldo-Zamorron returned separately to the Flamingo, Neuschwanger rode in Grimaldo-Zamor-ron’s car to the Tallcorn. While Neus- *971 chwanger waited in the car, Grimaldo-Zamorron went in and came out with a package in the front of his pants. Grimal-do-Zamorron gave the package, which contained a' pound of methamphetamine, to Neuschwanger in the parking lot at the Tallcorn. Neuschwanger suggested they drive to a cemetery so that he could count the money he was to pay Grimaldo-Za-morron. When they arrived at the cemetery, Neuschwanger signaled other officers to arrest Grimaldo-Zamorron.
The task force obtained search warrants for the room at the Flamingo and for apartment 714 at the Tallcorn. The search revealed no controlled substances at the Flamingo. At the Tallcorn, Escobe-do-Romero was found in apartment 714 along with Barb Thompson and her daughter. The officers found 86.5 grams of cocaine in a jacket in the closet and $564 in cash. The owner and manager of the Tall-corn informed an agent that she had seen Grimaldo-Zamorron going into apartment 728 earlier that day. The agent checked the registration and found that apartment 728 was rented to Grimaldo. The police then obtained an additional warrant to search Grimaldo’s apartment, where they found him along with 52.2 grams of methamphetamine, 25.2 grams of cocaine, and $1190 in cash.
Grimaldo and Escobedo-Romero were tried together. The jury acquitted them of the June 8 sale, but convicted both for conspiracy to distribute methamphetamine. Grimaldo was also convicted of two counts of distribution of methamphetamine, one on June 12 and one on June 25. Escobedo-Romero was acquitted of the June 12 sale, but convicted of possession of cocaine with intent to distribute. 4 The district court found that the conspiracy was responsible for sixty pounds of methamphetamine. It attributed three pounds of that to Grimaldo and sentenced him to the mandatory minimum of 120 months. The court attributed two pounds of the methamphetamine and the cocaine found in the jacket to Escobedo-Romero and sentenced him to seventy months. Gri-maldo and Escobedo-Romero appeal.
II.
Perhaps the most important legal issue raised in this appeal is whether the Supreme Court’s decision in
Jones v. United
States,
A.
Grimaldo and Escobedo-Romero argue that, in light of Jones, the district court erred by determining drug quantity as a sentencing factor. In Johnson, the Court reiterated that new rules for the conduct of criminal prosecutions apply retroactively to all cases pending on direct review. 5 *972 See id. We look first, therefore, at whether the intervening Jones decision established a new rule for the conduct of criminal prosecutions. The Jones Court interpreted the federal carjacking statute, which then read:
Whoever, possessing a firearm ..., takes a motor vehicle ... from the person or presence of another by force and violence or by intimidation, or attempts to do so, shall—
(1) be fined under this title or imprisoned not more than 15 years, or both,
(2) if serious bodily injury (as defined in section 1365 of this title) results, be fined under this title or imprisoned not more than 25 years, or both, and
(3) if death results, be fined under this title or imprisoned for any number of years up to life, or both.
18 U.S.C. § 2119 (Supp. V 1993). The district court found by a preponderance of the evidence that one of the victims of the carjacking in which Jones was involved suffered serious bodily injury and sentenced Jones to twenty-five years in prison.
See Jones,
The Court determined that the statute was unclear and construed it to contain three separate offenses rather than one offense with three sentencing options.
See id.
at 234, 251-52,
Any argument that Jones requires us to interpret drug quantity as an element of a 21 U.S.C. § 841 offense is foreclosed by the language of the, statute and by circuit, precedent. The structure and plain language of the statute leave no doubt that drug quantity is a sentencing factor. Section 841(a), titled “Unlawful acts,” states
Except as authorized by this subchap-ter, it shall be unlawful for any person knowingly or intentionally—
(1) to manufacture, distribute, or dispense, or possess with intent to manufacture, distribute, or dispense, a controlled substance; or
(2) to create, distribute, or dispense, or possess with intent to distribute or dispense, a counterfeit substance.
21 U.S.C. § 841(a) (1994). Section 841(b), titled “Penalties,” provides that a person who violates subsection (a) “shall be sentenced as follows” and contains a variety of sentencing ranges that are based in large part on drug quantity findings. 21 U.S.C. § 841(b) (1994 & Supp. IY 1998). Also, on several occasions, we have held that drug quantity is a sentencing factor rather than an element of the crime defined in section 841(a).
See, e.g., United States v. Holt,
B.
In
Jones,
the Court explained the principle underlying its position that if the carjacking statute were construed to contain
*973
sentencing enhancements it might be unconstitutional: “[A]ny fact (other than pri- or conviction) that increases the maximum penalty for a crime must be charged in an indictment, submitted to a jury, and proven beyond a reasonable doubt.”
Section 841(b) contains a variety of sentencing ranges that depend on the type and quantity of drug involved in the offense as well as on other factors, including prior convictions. Most importantly for our purposes, however, the maximum sentences increase dramatically as the quantity increases. For example, the maximum sentence for a crime involving methamphetamine can be twenty years, forty years, or life, depending solely on the quantity involved in the offense. Thus, if any fact other than recidivism that increases the maximum sentence for a crime must be charged in the indictment and proven to a jury beyond a reasonable doubt, treating drug quantity as a sentencing factor with none of these procedural protections would violate this rule.
To determine whether treating drug quantity as a sentencing factor is constitutional error in light of
Jones,
we briefly review earlier Supreme Court decisions that deal with the due process requirements for conviction and sentencing. In
Specht v. Patterson,
Soon after, the Court made clear that due process requires that “every fact necessary to constitute the crime” charged be proven beyond a reasonable doubt.
In re Winship,
The Court then struck down a state law that required a defendant charged with murder (punishable by life in prison) to prove that he acted in the heat of passion on sudden provocation in order to reduce his crime to manslaughter (punishable by a maximum of twenty years in prison).
See Mullaney v. Wilbur,
In
McMillan v. Pennsylvania,
Finally, the Court interpreted 8 U.S.C. § 1326 to define one crime: a deported alien returning to the United States without special permission.
See Almendarez-Torres v. United States,
Exactly one year after Almendarez-Tor-res was decided, the Supreme Court decided Jones, in which it held that factors that increase the maximum sentence for the crime of carjacking are elements of the offense. These cases illustrate that the Court has long been grappling with the due process requirements for conviction and sentencing. The Supreme Court’s failure to conclusively resolve the constitutional issues raised by these cases and discussed in Jones leads us to doubt that the Court announced a new rule for criminal prosecutions that must be applied retroactively.
Even if the Court later embraces the principle it announced in footnote 6 of
Jones
as established law, any error made by the district court must be plain at the time of appellate consideration.
See Johnson,
We are not certain that the Constitution requires that any fact, other than prior conviction, that increases the maximum penalty for a crime must be charged in the indictment and proven to a jury beyond a reasonable doubt. Until this constitutional principle is established, rather than sug *975 gested, we decline to find plain error under these circumstances.
III.
Escobedo-Romero challenges his convictions for possession of cocaine with intent to distribute and conspiracy to distribute methamphetamine, arguing that there was insufficient evidence to convict him. We review the sufficiency of the evidence to sustain a conviction de novo.
See United States v. Brooks,
The elements of the crime of possession of cocaine with intent to distribute are knowing possession of cocaine and the intent to distribute it.
See United States v. Rodgers,
To prove Escobedo-Romero guilty of conspiracy to distribute methamphetamine, the government must have shown that a conspiracy existed, that Escobedo-Romero knew of the conspiracy, and that he knowingly became a part of the conspiracy.
See United States v. Rork,
The government argues that four pieces of evidence support Escobedo-Romero’s conviction for conspiracy: (1) Brown testified that Grimaldo-Zamorron told him to go to the Tallcorn and talk to Julio and Armando on June 8, (2) Escobedo-Romero was present when Brown purchased methamphetamine from Grimaldo-Zamorron on more than one occasion and when he paid $400 to Grimaldo-Zamorron on June 11, (3) Brown said he bought drugs from members of the conspiracy, including Es-cobedo-Romero, and (4) Thompson testified that she purchased cocaine and methamphetamine from Escobedo-Romero. The record does not support points (3) and (4). Neither Brown nor Thompson testified that they made purchases from Esco-bedo-Romero. Thompson did testify that he gave her drugs, but that she never paid for them.
If the government’s case must rest on points (1) and (2), it is indeed weak.
*976
Brown’s testimony regarding the June 8 transaction shows that Escobedo-Romero probably answered the door when Brown arrived at apartment 714 and that he spoke to Brown. Brown testified that their conversation was social and had nothing to do with drugs. Grimaldo was the one who gave Brown the methamphetamine. The fact that Escobedo-Romero was present when Brown engaged in drug-transactions with others does not prove his guilt. “Mere presence at the location of the crime alone, even when coupled with knowledge of that crime, is not sufficient to establish guilt on a conspiracy charge.”
United States v. Hernandez,
Other evidence, not pointed to by the government, supports Escobedo-Romero’s conviction for conspiracy. Rivas testified that Grimaldo-Zamorron stored as much as two pounds of methamphetamine at Es-cobedo-Romero’s apartment when they lived with him in March. The drugs were stored in the living room closet where Grimaldo-Zamorron kept his things and wrapped so that they were not readily identifiable. Rivas stated, however, that Grimaldo-Zamorron sold methamphetamine from the apartment while they lived there and that Escobedo-Romero was present during some of these transactions. After Grimaldo-Zamorron and Rivas moved out of the Tallcorn and after Gri-maldo returned from Mexico in May, Gri-maldo-Zamorron told Rivas that he was storing methamphetamine at his brother’s place at the Tallcorn. Grimaldo lived with Escobedo-Romero until June 18. In addition, Grimaldo-Zamorron told Brown to go see Escobedo-Romero and Grimaldo on June 8. Escobedo-Romero was present when Grimaldo gave Brown methamphetamine that day, and Brown testified that Grimaldo got it out of the living room closet in apartment 714.
A jury could reasonably infer that Esco-bedo-Romero knowingly allowed Grimal-do-Zamorron to store methamphetamine in the closet of apartment 714, particularly because he was aware that both Grimaldo-Zamorron and Grimaldo distributed methamphetamine from the apartment. Because the evidence sustains the conclusion that Escobedo-Romero knowingly allowed his apartment to be used for the storage and distribution of methamphetamine, substantial evidence supports his conviction for conspiracy.
See Salinas v. United States,
IV.
Both Grimaldo and EscobedoRomero argue that the district court erred by failing to suppress the evidence found in Grimaldo’s apartment. EscobedoRomero lacks standing to challenge the search because he could have had no reasonable expectation of privacy in Grimaldo’s apartment.
See United States v. Washington,
Only after the officers completed the search of apartment 714 did they discover that Grimaldo had a separate apartment in the Tallcorn Towers. The owner of the building informed one of the agents that she saw Grimaldo-Zamorron entering apartment 728 that morning. The agent checked the registration and found that *977 Grimaldo rented 728. Grimaldo’s lease began on June 18, only one week before the bust and the subsequent searches.
The affidavit supporting the search warrant spelled out in some detail the particulars of the methamphetamine conspiracy. It included the - fact that a confidential informant had previously acquired methamphetamine from Grimaldo in apartment 714 at Grimaldo-Zamorron’s direction on two occasions. The affidavit also stated that Grimaldo-Zamorron made two trips to the Tallcorn on June 25, and that the police became aware that Grimaldo was renting apartment 728 that same day. Looking at the evidence as a whole, we hold that there was probable cause to issue a search warrant for Grimaldo’s apartment at the Tallcorn.
V.
Grimaldo and Escobedo-Romero argue that the district court erred by admitting certain evidence, including documents, hearsay statements, audiotapes, and Rosales’s testimony. “We will not reverse a district court’s evidentiary 'rulings unless they constitute a clear and prejudicial abuse of discretion.”
United States v. Withom,
We have considered the list of alleged evidentiary errors and reviewed the transcript for each. The district court admitted Rosales’s 'testimony, which related to matters entirely outside the time frame of the charged conspiracy, under Fed.R.Evid. 404(b). The court instructed the jury that the testimony could only be used to determine whether the defendants had the knowledge and intent necessary with respect to the crimes for which they were on trial. The court emphasized that any past similar acts were not evidence that either Grimaldo or Escobedo-Romero committed such an act in this case. Rosales did make some hearsay statements, but the court instructed the jury to consider only what he actually observed, not what he heard from other people. After reviewing Rosales’s testimony along with the court’s instructions, we find no abuse of discretion.
The district court did improperly admit hearsay testimony from a member of the task force because it believed that he was testifying about what he heard on a surveillance tape of the June 12 transaction. Once the court became aware that the officer was relying on the statements of Brown and Carr, rather than, on the audiotape, it reversed its ruling and told the jury not to consider the testimony regarding the transaction as proof of the transaction. Later testimony from Brown and Carr regarding the same transaction was substantially similar to the officer’s testimony. We conclude that even if there was error, it was harmless beyond a reasonable doubt.
The defendants’ remaining evidentiary challenges 6 are similarly without merit and require no farther discussion. The district court did not abuse its discretion.
VI.
Finally, Escobedo-Romero and Grimaldo argue that the district court erred in its calculation of drug quantities attributable to them. We review determinations of drug quantity attributable to a defendant for clear error.
See United States v. Sales,
For the foregoing reasons, we affirm the judgment of the district court.
Notes
. The Honorable Ronald E. Longstaff, United States District Judge for the Southern District of Iowa.
. Rivas alleged that the substance was methamphetamine, but laboratory tests showed that it was amphetamine.
. Carr, whose father was a member of the Mid-Iowa Drug Task Force, agreed to help the task force by going with Brown to pick up the methamphetamine.
. The judgment in Escobedo-Romero's case erroneously lists this offense as "Distribution of Cocaine.” Both the indictment and the verdict correctly refer to possession of cocaine with intent to distribute. Either crime is prohibited by the same statutory provision, 21 U.S.C. § 841(a)(1).
. After Johnson was convicted of perjury under 18 U.S.C. § 1623 and before her appeal,
United States v. Gaudin,
. The defendants argue that it was error to admit the audiotapes designated as Exhibits 1A, 2A, 3A, 4A, 5A, 8B, and 10B. They also argue that it was error to admit the documents designated as Exhibits 11J, 11T, 11U, 11Q, and 11S. Finally, they argue that it was error to admit Rivas’s testimony regarding statements made to her by Grimaldo-Zamor-ron and an officer's testimony regarding a June- 15 conversation between Brown and Grimaldo-Zamorron.
