Opinion for the court filed by Circuit Judge RANDOLPH.
This appeal from a criminal conviction raises an old problem. The government’s evidence falls short of proving guilt beyond a reasonable doubt. Nevertheless, the trial court denies the defendant’s motion for judgment of acquittal. The defense puts on its case and the defendant takes the stand. The jury then returns a verdict of guilty. Perhaps the defendant’s demeanor, itself evidence, caused the jury to infer that the truth was the opposite of what the defendant said. However, as Judge Learned Hand wrote in
Dyer v. MacDougall,
I
Charmaine Y. Zeigler was tried before a jury for possessing with intent to distribute crack cocaine, 21 U.S.C. § 841(a) & (b)(l)(B)(iii); and for using and carrying firearms during and in relation to that offense, 18 U.S.C. § 924(c)(1). Her co-defendant, Devon A. Waite, faced these charges and the additional charge of knowingly receiving, possessing, and transporting firearms in interstate commerce after having been previously convicted of a felony. 18 U.S.C. § 922(g)(1).
The government’s evidence showed that police officers executing a search warrant forcibly entered an apartment at 11 Galveston Place, Southwest. The apartment, formerly two units side by side, occupied the top floor of a small two story building. Facing the front of the building, Waite’s bedroom had been the living room of apartment # 3, on the building’s left side. A rear door in this room led to a hallway. Directly across the hallway was a kitchen, in the far left rear of the apartment. Down the hallway and adjacent to the kitchen was a bedroom. Apartment #4, on the right side, had the same configuration, with a living room in the front; a laundry room (apparently a former kitchen) across the hallway in the right rear of the apartment; and an adjacent bedroom. The two apartments had been converted to one. The hallway in each, which separated the front rooms and the kitchen (or laundry room) and each apartment’s bedroom in the rear, now ran the entire width of the apartment.
After the officers entered, they found three people inside, each of whom they placed in custody. The officers spotted Waite crossing the hallway between his bedroom and the kitchen, on the left side of the apartment. They found Zeigler in Waite’s bedroom. A third individual, Angela Hicks, was in the bedroom of former apartment # 4, on the right side.
The search of Waite’s bedroom turned up a small bag of marijuana on the headboard of the bed; a Ruger .22 caliber semiautomatic pistol on the floor behind a chair; $254 in cash and a money order on the dresser; also on the dresser, an ammunition pouch containing two speed loaders each with six rounds of .38 caliber ammunition. In the trash can in the kitchen across from Waite’s bedroom was a loaded Sports Arms .38 caliber revolver.
Down the hallway, in the living room, the officers found $533 in cash under a seat cushion, a bag of marijuana, and 7 rounds of 9 millimeter ammunition in a teapot.
■ The door to the laundry room, in the right rear corner of the apartment opposite the living room, was locked with a hasp and a padlock. The officers ripped the lock from the door and entered. Inside was a washing machine and a maroon briefcase, locked with combination locks. The briefcase contained 5.5 grams of crack cocaine, a razor blade, a Walther PPK .38 caliber semiautomatic handgun, $740 in U.S. currency, and two money orders.
Apart from the clothes she was wearing and the bag of marijuana, the officers found no personal effects of Zeigler’s in the apartment — no documents, personal papers, bills, extra clothing, or the like.
While the search was underway, the officers moved Zeigler, Waite, and Hicks to a couch in the living room, and asked each of them their name and where they lived. Zeigler identified herself and said she lived at “11 Galveston Place, Southwest.”
After presenting this evidence, the government called Barbara Anderson, the owner of the apartment building. She testified that she rented the top floor of the building to Waite and collected the rent from him, either in cash or money orders. Anderson thought Zeigler “lived” there with Waite. She based this conclusion on her seven or eight visits to the building between the summer of 1990 and October 2, 1990, when the search took place. During these visits she saw Zeigler, although not each time. She also called Waite; Zeig- *847 ler answered the telephone. On one occasion, Zeigler — in response to Anderson’s question about a crib standing just outside Waite’s bedroom — said she was pregnant. (The police did not find a crib in the apartment.) Anderson also believed that Waite had rented part of his apartment to another woman and that a George Pope also lived there for a time.
At the close of the government’s case, 1 Zeigler (and Waite) moved, pursuant to Rule 29, Fed.R.Crim.P., for a judgment of acquittal. The district court summarily denied the motions.
Waite then put on his defense. He produced three witnesses to support his theory that the top floor apartment consisted of two distinct apartments, and that while the cocaine had been found in the right portion of the apartment, Waite exclusively occupied the left. Waite did not testify.
Zeigler took the stand in her defense. She admitted that the marijuana in Waite’s bedroom was hers. She said that Waite was her boyfriend; that she had “been staying [at his apartment] off and on for two or three months”; that she stayed only in the portion formerly used as apartment # 3 and never ventured to the other side; and that Angela Hicks occupied the other side. According to Zeigler, she did her laundry at a laundromat with her mother, did not know there was a washing machine in the apartment, had never seen the door to the laundry room, and did not know who had the combination to the padlock on the laundry room door. She denied seeing any cocaine or guns in the apartment. When asked about the maroon briefcase, Zeigler said that she had never seen Waite with it but “Angie had a briefcase like it.” She disclaimed any knowledge of the combinations to the locks on the briefcase.
Zeigler’s parents also testified. According to her mother, Zeigler stayed at Waite’s apartment only a few nights a week. On her three visits to Waite’s apartment, her daughter and Waite were occupying only the left side of the apartment. Zeigler’s father testified that his daughter lived with him during August and September of 1990, although she did not spend every night at home.
The jury acquitted Zeigler (and Waite) of possession with intent to distribute and of possession of a firearm in relation to that offense. The jury convicted Zeigler (and Waite) of the lesser included offense of possession of a controlled substance. 21 U.S.C. § 844(a). Waite was also convicted of one count of unlawful possession of a firearm.
At the close of evidence, Zeigler had renewed her motion for a judgment of acquittal, as had Waite. After the verdict the district court denied the motions in a memorandum opinion. As to Zeigler, the court stressed her relationship with Waite and her frequent presence in the apartment. The court also found “as the jury obviously did, that much of Zeigler’s testimony was not credible insofar as it was intended to protect Waite.” She testified “that she never saw guns ... in the apartment, although there was other testimony that weapons [and] weapons accessories ... were in plain view in the bedroom in which Zeigler was present at the time of her arrest.” 2

A
The general issue is whether sufficient evidence supports Zeigler’s conviction for possession of the cocaine. Viewing the government’s evidence in the light most favorable to it, we do not detect enough proof to connect Zeigler to the cocaine found in the
*848
laundry room. Nothing indicated that she actually possessed the cocaine. Her guilt depended on the government’s proving beyond a reasonable doubt that she constructively possessed it, that she “knew of, and was in position to exercise dominion and control over” the cocaine.
United States v. Byfield,
Even if there were evidence of Zeigler’s knowledge of the cocaine, the government’s case would still fall short. Zeigler was near the cocaine, down the hallway from it when the police arrived. But “ ‘mere proximity or accessibility to contraband will not support a conclusion that an individual had knowing dominion and control over it.’ ”
United States v. Williams,
B
The trial court therefore erred in denying Zeigler’s motion for a judgment of acquittal made at the close of the government’s case-in-chief. But this error does not in itself warrant reversing her conviction. Our
en banc
decision in
United States v. Foster,
Zeigler’s sufficiency claim therefore must be evaluated in light of all the evidence introduced at trial, including evidence the defense presented.

Dyer v. MacDougall
began as an action for libel and slander. The plaintiffs only witnesses would have been the two defendants. His plan was to call them to the stand, have them deny uttering the slanders, and hope the jury, in light of their demeanor, would believe the opposite of what they testified. Because in such event there could be no effective appellate review of a verdict in the plaintiffs favor, Judge Hand ruled for the
*849
court that the defendants were entitled to summary judgment. To be sure, a witness’s demeanor “is a part of the evidence.”
Juries in criminal cases, like juries in civil actions, may and should take a witness’s demeanor into account. Perhaps the jury here treated Zeigler’s testimony, in light of her demeanor, in the manner described by Judge Hand. If it made “negative” inferences, these would have supplied enough evidence to convince any rational juror of her guilt beyond a reasonable doubt. Inferring the opposite of what she testified — as the government supposes the jury did — would mean that for months Zeigler had been living full-time with Waite in the apartment; that she ventured throughout the apartment; that she saw cocaine and guns in the apartment; that she knew of the laundry room, knew it was locked and knew who had the combination to the lock; and — most important — that she had the combinations to the locks on the briefcase containing the cocaine.
This raises an obvious problem. It is not only impossible to determine whether the jury made all or any of these negative inferences, but also impossible to judge whether it would have been justified in doing so. Jury deliberations are secret. Demeanor evidence is not captured by the transcript; when the witness steps down, it is gone forever. An appellate court cannot evaluate it, and therefore cannot determine how a rational juror might have treated it. The situation would be different if the defendant’s testimony, on its face, were utterly inconsistent, incoherent, contradictory or implausible. Then an appellate court would have some assurance that when the defendant said “black” the jury reasonably could have concluded that the truth was “white.” This may have been the situation as the plurality saw it in Wright v. West, 3 but it is not the situation here. Zeig-ler’s testimony relating to the cocaine in the briefcase was hardly implausible.
Because we cannot evaluate demeanor, a decision along the lines the government proposes would mean that in cases in which defendants testify, the evidence invariably would be sufficient to sustain the conviction. We would in each such case assume the jury correctly evaluated the evidence. In explaining how this could be so in light of the defects in the government’s proof, we would reason backwards to the only explanation available — the defendant’s demeanor. This sort of approach, beginning with the hypothesis that the jury must have gotten things right, contradicts the reason why appellate courts review convictions for sufficiency of evidence — that juries sometimes get things wrong.
Jackson v. Virginia,
We have considered the possibility of a middle ground, of a rule such as this: when the government has presented at least
some
*850
evidence of guilt, an appellate court may add negative inferences from the defendant’s testimony to sustain the conviction. The Second Circuit has rejected the idea: “Although [demeanor] is a legitimate factor for the jury to consider, this could not remedy a deficiency in the Government’s proof if one existed.”
United States v. Sliker,
Only speculation supports Zeigler’s conviction. We cannot determine whether Zeigler, by her demeanor on the stand, supplied the evidence needed to support her conviction. It is true that the traditional method of reviewing the sufficiency of evidence in criminal cases itself involves some speculation. We take the evidence in the light most favorable to the government, yet we cannot be sure the jury took it that way. But at least we draw inferences from the record. We do not begin and end on nothing more than a guess about what the jury might have observed at trial. Appellate review of the sufficiency of evidence protects against wrongful convictions. We refuse to destroy the protection in cases in which defendants testify.

Notes
. The government also presented several expert witnesses who testified about the guns, the chemical analysis of the cocaine, and the modus oper-andi of drug dealers.
. Zeigler also moved for a new trial on the basis of newly discovered evidence contained in an affidavit of Angela Hicks. Defense counsel stated that he had been unable to locate Hicks prior to trial. In her affidavit executed after trial, Hicks swore that she had been living on the right side of the apartment for about a month before the search; that she had been taken there by "Tony Ford”; that Ford was the only person she had ever seen go into the laundry room (where the cocaine was discovered); that she — Hicks— owned a "brown burgundy briefcase" while she was living in the apartment but that she did "not know what happened to it.” The court denied the motion.
