After the jury was unable to reach a verdict in Ms first trial, Marlin Simpson was convicted on retrial of possession with intent to distribute crack cocaine and of using or carrying a firearm during and in relation to a drug trafficking offense. Simpson appeals, claiming: (1) because there was no manifest necessity for the first mistrial, his retrial was barred by the Double Jeopardy Clause; and (2) the evidence was Msufficient to support Ms conviction on either count. Simpson also challenges the use of a prior battery cоnviction in Ms sentencing calculation on the ground that the government failed to provide sufficient evidence of the validity of that conviction.
I.
Officers of the WicMta Police Department, acting on information from a confidential informant, obtained a search warrant for a residence located at 2350 North Erie in WicMta. The residence was listed in the city directory as belonging to Marlrn Simpson and Ms grandmother, Hazel Simpson.
Prior to executing the warrant, officers surveyed the residence and оbserved various people arrive, stay inside for one to five minutes, and then leave. Officers then observed Simpson exit the residence and climb into the passenger side of a Chevy Nova. The stream of visitors at the residence ceased when Simpson left. As Simpson left the residence, he was carrying a handgun, wMch he appeared to place under the passenger side front seat. When officers stopped Simpson a short distance away, he was riding in a second Chevy Nova being towed by the first Chevy Nova that he had been observed entering. A loaded Glock 9mm handgun was under the front seat of the veMele in wMch Simpson was riding, and he had a pager on Ms person. No drugs were found in the car or on Simpson’s person.
When the warrant was executed at 2350 North Erie, a detective searched the room *1376 that Simpson’s grandmother identified as Simpson’s bedroom. The detective found: crack cocaine, including eight one-ounce bags of crack in a Redskins jacket in the closet; scales, bаking soda, which is often used to cook cocaine into crack, and other drug paraphernalia; $480 in cash; and ammunition. The detective also discovered photographs of Simpson and Simpson’s girlfriend, and mail addressed to Simpson at that address. After searching the house, police searched five people they found inside. Simpson’s uncle, Ronald Simpson, was found with approximately 26 grams of crack cocaine on his person.
Simpson was charged in a superseding indictment with conspiring with Ronald Simpson to distribute crack cocaine in violation of 21 U.S.C. § 846, possessing with intent to distribute crack cocaine in violation of 21 U.S.C. § 841(a)(1), and using or carrying a firearm during and in relation to a drug trafficking offense in violation of 18 U.S.C. § 924(c)(1). The conspiracy charge subsequently was dismissed. Simpson’s first trial ended in a mistrial after the judge determined that the jury could not reach a verdict. At Simpson’s second trial, the defense offered evidence that for six months preceding the execution of the search warrant Simpsоn had not been living at the North Erie address but had been living elsewhere with a cousin. Simpson claimed he had used the North Erie address only as a mailing address. The jury convicted Simpson of both counts, and Simpson appeals.
II.
Simpson first claims that his retrial subjected him to double jeopardy. When a mistrial is declared without the defendant’s consent, the Double Jeopardy Clause of the Fifth Amendment bars the retrial of the defendant unless there was “manifest necessity” for the mistrial.
Arizona v. Washington,
The events leading up to Simpson’s mistrial were as follows: Simpson’s trial began on the morning of September 13, 1994, and the case was submitted to the jury at 11:30 a.m. on September 14. Between 4:45 and 5:00 p.m. on September 14, the jury sent two questions to the trial judge, who responded in open court. The following portions of his response are relevant:
I will take your second question first: “Can we have a verdict on one count and not on the second?” Yes, you can have a verdict, as the instructions told you....
The seсond question where you said, “We are hung up. What do we do from this point?”...
I think I’ll excuse you for the evening and ask you to come back and continue your deliberations!,] ... and then if you cannot arrive at a verdict on all of the counts or on one of the counts — I take it your question was on one count and not on two counts. I don’t know what, but you can come in with a verdict on the one count of the indictment. I commend you to look at Instruction 26 [the elements of the 924(c) charge] in connection with your coming in with a verdict. Remember that in order to sustain his [sic] burden of proof for a charge of using or carrying a firearm during and in relation to a drug trafficking crime as charged in Count 2 in the indictment, the government must prove the following two essential elements beyond a reasonable doubt: First, that ... the defendant committed or aided and abetted in the commission of a drug trafficking crime charged in Count 1 of the indictment. So, in order to — in coming in with a verdict, you could not come in with a verdict on Count 2 alone. Your verdict would have to be on Cоunt 1, and then if you think that the use of the weapon was in connection with that, then you can find a verdict on Count 2.
(emphasis added). Before excusing the jury, the judge asked counsel if they had any objections to his remarks, and both counsel replied that they did not.
The jury resumed deliberations at 9:00 a.m. the next morning. At 10:35, in response to further communication from the foreman indicating that the jury still was having difficulty reaching a verdict, the judge sum *1377 moned the juiy into the courtroom. After some discussion, the judge asked the foreman: “[Do] you think there is any reasonable belief that by further consideration of the evidence by the jury you can reach a verdict, or are you hopelessly deadlocked?” The foreman responded, “Hopelessly deadlocked, Your Honor.” The court declared a mistrial. There was no objection by the defendant at any time during the exchange, including after the jury was discharged and the judge' set the case for retrial.
“It has been established for 160 years ... that a failure of the jury to agree on a verdict was an instance of ‘manifest necessity
1
which permitted a trial judge to terminate the first trial and retry the defendant.”
Richardson v. United States,
We accord the “highest degree of respect” to a trial judge’s finding of manifest necessity based on a hung jury.
Crotwell,
Simpson further argues that even if the jury was deadlocked, the impasse was caused by the trial judge’s error, and mistrial therefore was improper. Simpson alleges that the judge’s statement to the jury thаt it could not convict on the firearm count unless it convicted on the drug count was inconsistent with our language in
United States v. Hill,
We question Simpson’s premise that the jury deadlock was caused by trial judge error.
1
Even if we were to accept that premise, however, we would find no merit to Simpson’s argument. “[T]he double jeopardy clause does not require ‘manifest necessity’ for the events that triggered the mistrial; manifest necessity for the mistrial itself will ordinarily permit a second trial.”
United States v. Buljubasic,
III.
Simpson next challenges the sufficiency of the evidence underlying both his convictions. “In reviewing the sufficiency of evidence to sustain a jury’s guilty verdict, we examine the evidence in the light most favorable to the government in order to determine whether the evidence ... together with all reasonable inferences to be drawn therefrom, is substantial enough to establish guilt beyond a reasonable doubt.”
United States v. Johnson,
A.
We turn first to the firearm count. Simpson was charged with “using and carrying” a firearm in violation of 18 U.S.C. § 924(c). 2 At trial, evidence was presented that Simpson carried a handgun from the residence where the crack cocaine was found, and placed something under the passenger side of a vehicle. When Simpson was arrested in the second vehicle, a 9 mm handgun was under the front seat of that car, and the jury could have found that this gun was in Simpson’s presence during the earlier drug transactions in his home. In addition, some of the ammunition found in the bedroom containing the crack cocaine was 9 mm ammunition. The jury was instructed as follows:
The phrase “uses or carries a firearm,” for purposes of this case, means having a firearm available to assist or aid in the commission of the crime alleged in Count 1 of the indictment.
In determining whether the defendant used or carried a firearm, you may consider all of the factоrs received in evidence ... including the nature of the underlying crime of drug trafficking alleged, the proximity of the defendant to the firearm in question, the usefulness of the firearm to the crime alleged, and the circumstances surrounding the presence of the firearm.
A defendant “uses” a firearm when it (1) is readily accessible, (2) is an integral part of the criminal undertaking, and (3) increases the likelihood of success for that undertaking. The government is not required to show that a defendant actually displayed or fired the weapon to prove “use.” However, you must be convinced beyond a reasonable doubt that the firearm played a role in or facilitated the commission of the drug offense charged. (R.O.A., Vol. I, doc. 61, instruct. # 27)
The parties do not dispute that this instruction was correct at the time of Simpson’s trial. While this appeal was pending, however, the Supreme Court narrowed the broad definition of “use” that this circuit had previously applied and held that “[t]o sustain a conviction under the ‘use’ prong of
*1379
§ 924(c)(1), the Govеrnment must show that the defendant actively employed the firearm during and in relation to the predicate crime.” Bailey v. United States, - U.S. -, -,
We are guided in part by
Bailey
itself. There, the defendants, who were charged with both “using” and “carrying” a firearm, challenged the sufficiency of the evidence supporting their convictions.
Id.
at -,
Our inquiry is thus twofold: whether the jury was instructed under the proper legal standard and, if not, whether there is some evidence that would have supported a conviction under a proper instruction. We turn first to the proper standard. As Simpson was charged with both using and carrying a firearm, we must consider the jury instruction under both prongs. If the instruction as to one prong was legally erroneous, but the jury was correctly instructed on the other prong, we may affirm Simpson’s conviction if we can “determine with absolute сertainty that the jury based its verdict on the ground on which it was correctly instructed.”
United States v. Miller,
To support a finding that a defendant used a firearm for purposes of § 924(c), the government must prove that the defendant “actively employed” the gun.
Bailey, - U.S. at -,
We turn next to whether there was evidence that could have supported Simpson’s conviction under a proper jury instruction. We conclude there is no evidence that
*1380
Simpson actively employed the firearm. Although the jury could have concluded that Simpson had the gun in his pоssession while conducting drug transactions, the government offered no evidence that Simpson brandished, displayed, bartered, struck with, fired, disclosed, mentioned, or in any other way actively employed the firearm.
See Bailey, - U.S. at -,
B.
To support a conviction for possession with intent to distribute crack cocaine, the government must prove that Simpson knowingly possessed the substance with intent to distribute. Possession need not be actual, but may be constructive.
U.S. v. Culpepper,
Simpson claims the evidence was insufficient to support the conclusion that he had constructive possession of the drugs found in the bedroom at 2350 N. Erie. We disagree. Among the evidence linking Simpson to the bedroom were photographs of Simpson, and documents addressed to Simpson at 2350 North Erie, found in the room. The detective who searched the room testified that a baseball cap in the room matched a cap worn by Simpson in one of the pictures. Additionally, Simpson’s grandmother told the police that the room in which the crack cocaine was found was Simpson’s bedroom. Simpson himself, upon his arrest, gave his address to police as 2350 North Erie, and signed his bond papers with that address. A rational jury reasonably could infer that Simpson currently occupied that bedroom. Even if the jury concluded that Simpsоn was not currently living at the residence, it reasonably could conclude that Simpson continued to exercise dominion and control over the bedroom, and therefore was in constructive possession of the cocaine found therein.
See, e.g., Verners,
IV.
Finally, Simpson challenges the district court’s use of a prior conviction to enhance his sentence. The district court’s factual findings at sentencing are reviewed for clear error, while its interpretation of the Sentencing Guidelines is a question of law reviewed de novo.
United States v. Bridges,
The probation officer who prepared Simpson’s presentence report listed a conviction for battery dated April 25, 1994 in the Municipal Court оf Wichita, Kansas. The *1381 probation officer assessed one point to Simpson’s criminal history for this conviction, see U.S.S.G. § 4Al.l(c), thus raising Simpson’s criminal history category from I to II, and the applicable guideline range from 151-188 months to 168-210 months. Simpson objected that the battery conviction was the result of a guilty plea that his attorney had entered on his behalf without his permission. He asserted that he had never been sentenced and the case was not final because he intended to appeal the Municipal Court conviction. This appeal, he asserted, would result in a “trial de novo,” and therefore there was as yet no conviction.
The probation officer responded by obtaining a certified docket sheet from the Municipal Court in Wichita. The docket sheet indicates that the defendant pled nolo contendere to battery and was found guilty by the court on April 25, 1994. The district court concluded that neither Simpson’s stated intention to appeal the conviction nor the fact that Simpson had not yet been sentenced precluded the conviction from being counted. See U.S.S.G. §§ 4A1.2(a)(4) (“Where a defendant has been convicted of an offense, but not yet sentenced, such conviction shall be counted ...”); 4A1.2(Z) (“Prior sentences under appeal are counted except as expressly provided below.”). The court further concluded it could not entertain a collateral attack on the validity of the conviction, and overruled Simpson’s objections without conducting an evidentiary heаring.
On appeal, Simpson asserts that he is not challenging the constitutionality of the conviction or whether the conviction was countable under the Guidelines, but rather whether the district court “had sufficient evidence to conclude that the conviction was genuine.” Br. of Appellant at 28. The government must establish the fact of a prior conviction by a preponderance of the evidence.
United States v. Ortiz,
We believe that a сertified docket sheet is adequate, absent some contradictory evidence by the defendant, to establish the existence of a prior conviction for this sentencing purpose.
See, e.g., United States v. Dickens,
Simpson also argues that the conviction is not “genuine” because his counsel entered a plea without his consent. We have held that “with the exception of a collateral attack based on the complete denial of counsel, a district court sentencing a defendant under the career оffender provisions of the Guidelines cannot consider a collateral attack on a prior conviction.”
United States v. Garcia,
y.
Simpson’s conviction for violating 18 U.S.C. § 924(e)(1) is REVERSED and REMANDED for further proceedings. All other aspects of the district court’s judgment are AFFIRMED.
Notes
. Although Simpson is correct that a § 924(c) conviction may be sustained even in the absence of a conviction on the underlying drug count, it is clear that
"proof
of the underlying crime is an essential element of a substantive § 924(c) violation."
Hill,
. Simpson was indicted for “using and carrying” a firearm. However, 18 U.S.C. § 924(c)(1) defines the crime in the disjunctive, as did the instruction to the jury. "[A] crime denounced in the statute disjunctively may be alleged in an indictment in the conjunctive, and thereafter proven in the disjunctive.”
United States v. Parrish,
. Simpson filed a supplemental authority invoking Bailey, which was decided after his reply brief was filed, as support for his sufficiency claim.
