The appellant was indicted and convicted of Sodomy in the First Degree committed on a boy under 12 years of age. He was sentenced to twenty years in the penitentiary, and he appeals as a matter of right, claiming three errors:
1) The evidence was insufficient;
2) Error in admitting an exhibit, consisting of miscellaneous pictures, reading materials and personal memorabilia, seized from an apartment the appellant shared with a female companion, which lacked relevancy other than to bolster the prosecution’s unsubstantiated claim that he fit the profile of a “pedophile”; and
3) Error in the prosecutor’s repeated reference to the appellant as a “pedophile” when there was no evidence to support this charge.
We conclude there was evidence sufficient to support a conviction, but we reverse on points two and three stated above, for reasons that follow.
In April of 1989, Officer Gerald Curtis of the Maysville Police Department received a call from a social worker about a report of child molestation by the appellant. The alleged victim was a ten-year old boy. Curtis viewed the social worker’s tape recorded interview with the boy in which he stated, inter alia, that the appellant showed him pictures of naked boys and girls from a “Playboy” magazine, and Curtis then obtained a search warrant for “magazines containing photographs of an obscene and sexual nature.”
The police went to the apartment occupied by the appellant and his girlfriend and there seized various items from different locations within it which included in and under a bedroom bookcase and from within various boxes unidentified as to source or ownership. At trial a portion of this material was identified by the investigating officer, and then introduced as a group as “Exhibit 1.”
Exhibit 1 included: some old posters of former teenage idols, an article on adolescent sexual behavior on a page torn from “Hustler” magazine and another page from the same magazine with pictures on it of a naked man and two women with their sex organs exposed, a pamphlet entitled “First Hand” graphically illustrating and describing hard-core homosexual activity, miscellaneous pictures of boys cut out from various newspapers and other publications such as *649a mail order catalogue, and some nondescript notes from an individual named “Don.” It appears the pages and photographs torn or cut out of the magazines was done, at least in part, by the police during the process of gathering this material.
At trial the boy testified that appellant performed acts of oral sex on him, and, on occasion, appellant masturbated at the same time. He also explained that appellant was a neighbor who had befriended him, and he would often go to the appellant’s house to watch TV. Appellant had taken him to the library, horseback riding, and to play tennis. Sometimes appellant’s girlfriend went with them. The boy testified the appellant showed him pictures of “naked” girls and boys in “a ‘Playboy’ book,” but the boy was not asked to identify any of the material in “Exhibit 1” as having been shown to him. Commonwealth’s “Exhibit 1” was introduced solely through the testimony of Officer Curtis. When offered, the prosecutor advised the judge:
“He [the boy] just described what type of pictures he was shown, Judge. I don’t think the boy can identify any particular pictures.”
The investigating officer could not identify which among the materials seized belonged to the appellant, and which to his girlfriend. When the court commented as to one of the pictures, “This is just a picture of a ball club, isn’t it?”, the prosecutor responded, “He [the appellant] certainly could explain [it] to the jury if he testifies.”
Both the appellant and his girlfriend did testify. The appellant denied that any sexual acts occurred between him and the boy. He testified he let the boy watch TV because the boy’s TV at home was broken. He had taken him to the library, to play tennis, horseback riding, and even, on one occasion, on a visit to the home of the appellant’s grandmother in Ohio. He stated that the boy was angry because he did not buy new Reebok tennis shoes for him for Christmas, which he promised to buy if the boy’s grades at school improved. Since they did not improve, the appellant did not buy the shoes.
Appellant’s neighbor testified he saw the boy and another youth named Jonathan attempting to break into appellant’s apartment with a knife at the back door the day after Christmas. The boy’s mother testified that she brought her son to appellant’s house so he could apologize for the attempted break-in. The boy’s mother also testified she was having problems with the boy’s lying and had talked to the social worker about having him see a counselor for it.
The appellant identified some of the posters as belonging to his sister from years back when she was a teenager, and when the girlfriend testified she said some of the material seized was hers. During his testimony the appellant denied cutting out any of the obscene articles and pictures seized by the police, and said they were probably 10-15 years old. The obscene articles themselves were undated, except the pages from “Hustler” magazine were a “December” issue. Appellant identified “Don” as a fellow from the neighborhood who left these notes in an attempt to be friendly. Appellant said he stopped being friendly with Don when he suspected Don might be “gay.”
Originally appellant leased the apartment where the search was conducted, but at the time of the search the apartment had been leased in the girlfriend’s name, and the appellant was in the process of moving out. Appellant’s girlfriend identified some of the posters and other materials seized as belonging to her. Officer Curtis admitted he could not say whose magazines they seized and he did not know who cut out the articles.
The Commonwealth undertook to prove the appellant was a pedophile as central to its case. In his opening statement the prosecutor said “I think we’ll persuade beyond any doubt that this defendant is a pedophile.” This word has never been precisely defined for purposes of this case, nor *650has there been any clear explanation of what it is supposed to prove in this case.1
Officer Curtis, when undertaking to describe what was found as a result of the search of the apartment, said, inter alia, “and also there’s an article that, from a magazine that the author attempts to defend pedophallia [sic?].” Later on, at the end of his direct examination, the prosecutor asked Officer Curtis:
“Q. 26. You’ve used the word, pedophile. Tell the jury what pedophile means.
A. Pediphee (sic?) is the adult engaging in sexual activity with children.
Q. 27. Have you had any training regarding pedophiles?
A. Yes, sir.”
The prosecutor then asked Officer Curtis: “Basically, would you describe to the jury the behavior of a pedophile?” Whereupon defense counsel objected and the prosecutor did not pursue the matter further.
On cross-examination the officer was asked by defense counsel:
“Q. You only seized anything you thought might depict something as I believe the search warrant said, of a pornographic nature.
A. Anything that would — yes, sir, that would relate to, ah, possible characteristics of a pedophile.
Q. I see. And do you think that posters showing teen age stars or whatever is toward the aim of determining or finding something that would depict a pedophilia (sic)?
A. Not in and of itself, it could eventually fall into the characteristics of a pedophile compared with other material.”
In closing argument the prosecutor said: “[The police] came as close as proving what’s in this defendant’s mind as you can prove. No, we can’t ever get into his mind and say ‘here’s a picture of his mind. Here’s what he’s thinking. Here’s the perversion, the filth, the degradation and sickness of mind.’ We can’t show you all that, but we can show you what he had. Ladies and gentlemen, that’s a picture of a pedophile, pure and simple. Typical pedophile.”
In closing argument the prosecutor also said:
“I don’t think there’s any problem with the fact that David Dyer went out of his way to do things ... to take him riding, to promise to buy him things, then asked him over to the house to let him watch television, because this is typical, that’s what you do when you’re a pedophile. You treat them nice.”
At this point appellant’s counsel objected “to this constant use of a term here.” The court “sustained” the objection and admonished the jury: “Don’t consider his reference to the defendant being pedophile.” Of course, by this point it was far too late for such an admonition to have made any difference. Strangely enough, the prosecutor then continued the same line of argument by commenting at length on the contents of “Exhibit 1,” and the defendant’s objection to this was “overruled.”
The jury had a difficult time with this case. One and a half hours after they began deliberating they told the judge: “We just feel that we have not had enough evidence.” They then asked to view the videotape of the child’s interview with the social worker and were told the tape was not part of the evidence. When asked why the social worker had not been called to testify the judge responded “I am just the judge.” The jury went back to deliberate and approximately two and a half hours later they informed the court that they couldn’t agree. The Allen charge was then given. One hour later the jury reached a “guilty” verdict.
The first question is whether there was evidence to convince the jury beyond a reasonable doubt sufficient to comply with the standard in Commonwealth v. Sawhill, *651Ky., 660 S.W.2d 3 (1983), and the federal due process standard established in Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979), especially in light of what occurred after the jury began deliberating. At the threshold the Commonwealth argues the issue is not preserved because the defendant’s motion for a directed verdict at the close of the Commonwealth’s case was not renewed at the close of all the evidence, citing our Court’s Opinion in Commonwealth v. Blair, Ky., 592 S.W.2d 132, 133 (1980), in which this Court stated:
“The procedural rule, as clarified in Kimbrough [Kimbrough v. Commonwealth, Ky., 550 S.W.2d 525 (1977)], is that in order for the issue of the sufficiency of the evidence to be preserved for appellate review, the party wishing to use the insufficiency as a basis for his appeal must have moved for a directed verdict at the close of all the evidence, not just at the close of the Commonwealth’s case in chief.”
The Kimbrough rule is sound where the defense presents evidence after the Commonwealth’s case which may have been sufficient to cure any evidentiary insufficiency, but Kimbrough is at best a state procedural rule which must give way to the constitutional mandate that a conviction based on insufficient evidence cannot stand. Indeed, Blair, Borders, and Carpenter, whose convictions were affirmed by our Court in Blair, supra, were later held entitled to relief by way of habeas corpus in Carpenter v. Leibson, 683 F.2d 169 (6th Cir.1982), the U.S. Court of Appeals stating (Id., 172-73):
“Since it was not even contended that the evidence offered by the defendants after the denial of their motions for a directed verdict supported the Commonwealth’s case, the state had no legitimate interest in requiring a renewal of the motion for a directed verdict.

There is really no need to determine whether the Supreme Court of Kentucky properly applied a new rule or not in Kimbrough, as the Supreme Court [of Kentucky] nevertheless should have ruled on the sufficiency of the evidence under the facts and circumstances existing in the present case.”
Unlike a decision of the United States Supreme Court, our Court is not bound in subsequent cases by a United States Court of Appeals’ decision. Cf. Conklin v. Commonwealth, Ky., 799 S.W.2d 582 (1990). But the reasoning in Carpenter v. Leibson on this point is persuasive. In criminal cases the application of the procedural rule in Kimbrough and Blair must be limited to situations where the evidence adduced subsequent to the defendant’s motion for a directed verdict is sufficient to cure any evidentiary shortfall which exists at the time it is made.
The problem for the appellant in this case is the evidence fails to raise a question of sufficiency; it raises only a question of credibility. Even if the evidence of the alleged victim is viewed as uncorroborated, standing alone it is still sufficient to prove all the elements of the crime charged, and to create a jury issue. It has long been the rule in Kentucky in rape cases that “the unsupported testimony of the prosecutrix, if not contradictory or incredible, or inherently improbable, may be sufficient to sustain a conviction,” Robinson v. Commonwealth, Ky., 459 S.W.2d 147, 150 (1970), and there is no rationale for a different rule in a sodomy case. Here, although uncorroborated, the testimony of the alleged victim is neither self-contradictory, incredible, nor inherently improbable, and standing alone it is sufficient to withstand a challenge under Commonwealth v. Sawhill, supra, and Jackson v. Virginia, supra, even though the bulk of the evidence mitigated against it.
Unfortunately, although the boy’s testimony was sufficient to make a case, the Commonwealth, unwilling to rest its case on the boy’s testimony, sought to bolster that testimony with the contents of the appellant’s bookcase. But the boy never established relevancy by identifying any of the evidence seized from the apartment shared by the appellant and his girlfriend *652as having been shown to him. At the time the material in Commonwealth’s “Exhibit 1” was offered, it was with the excuse that “it supports the child’s testimony that he was shown this type of literature.” The Exhibit falls far short of this claim. The material in “Exhibit 1” is far beyond the boy’s description of what he saw in the appellant’s apartment. It is obvious the real purpose, the sole purpose, of this evidence was, in general, to prove the appellant was a sexual pervert, and, in particular, to prove that his perversion was pedophilia, and to do so on the basis of reading material found in his possession some of which would offend a substantial number of jurors, prejudicing them against the appellant without regard to whether it proved anything against him. The various pornographic pictures and articles and the nondescript photographs and memorabilia were devoid of meaning except that provided by the investigating police officer’s testimony and the prosecutor’s argument labeling the material seized proof that the appellant was a pedophile.
We declare, unqualifiedly, that citizens and residents of Kentucky are not subject to criminal conviction based upon the contents of their bookcase unless and until there is evidence linking it to the crime charged. If the boy’s testimony was intended to be the connecting link, evidence would be limited to that which the boy could identify as having been shown to him. If this material is supposed to provide a picture of the appellant as a pedophile, such profile evidence is inadmissible in criminal cases to prove either guilt or innocence. Hampton v. Commonwealth, Ky., 666 S.W.2d 737, 742 (1984), presented a far stronger case for admitting profile evidence than this one, and, nevertheless, we held the trial court had properly excluded as irrelevant
“... evidence from a witness designated a ‘clinical social worker,’ who then testified by avowal that in his opinion the appellant ‘would not have’ become involved with the twelve yeár old victim because ‘based on (appellant’s) psychological development, by history,’ this victim was too young to attract the appellant.”
In Hampton, we held:
1) A social worker is not “qualified as an expert to express an opinion” on the mental condition at the time of the act of a person criminally accused.
2) “The testimony as proffered went to the ultimate question of the guilt or innocence of the appellant, ...”
3) “Mitigating” evidence (and, conversely, aggravating evidence) does not qualify as admissible except perhaps as “background information” in the penalty phase of a death penalty case.
We have long recognized a distinction between testimony about the mental condition of an accused and “his actual mental attitude at a particular time and place” when he allegedly committed a crime, Koester v. Commonwealth, Ky., 449 S.W.2d 213, 215 (1970), stating:
“It is the difference between an objective opinion and a subjective conclusion, [citation omitted.] Or put another way, it is the difference between the mental abnormality and the specific ‘product’ produced thereby.”
In Pendleton v. Commonwealth, Ky., 685 S.W.2d 549, 553 (1985), we held “[t]he trial court correctly refused Pendleton’s attempt to introduce the testimony of psychologist Kroger.... to the effect that Pendleton’s psychological profile was not consistent with that of a sex offender.” We stated:
“An opinion as to whether the accused had the ability or propensity to commit such an act [sodomy of a six year old] is improper because it is an opinion on the ultimate fact, that is, innocence or guilt." Id.
If the testimony of a trained psychologist to the effect that the accused does or does not have a “profile ... consistent with that of a sex offender” is inadmissible, a fortiori, the testimony of an investigating police officer that an accused has the profile of a pedophile, based on the contents of his library and miscellaneous memorabilia found in his residence, *653falls short of the threshold of admissible evidence. Officer Curtis’ opinion suffers from all of the defects covered in Koester, Hampton and Pendleton, plus failing to meet elementary principles involved in determining relevancy. See Lawson, Kentucky Evidence Law Handbook, § 2.00 (2d ed. 1984). The trial court’s decision to admit the Commonwealth’s “Exhibit 1” as evidence in this case was prejudicial error.
Further, because the contents of Commonwealth’s “Exhibit 1” were central to the Commonwealth’s opening and closing argument to the effect that the Commonwealth would prove, and did prove, that the appellant was a pedophile, and to the testimony of the investigating police officer in support of this premise, these comments and this testimony were improper. The Commonwealth argues lack of preservation to this line of argument and testimony. The appellant responds that since his counsel objected vehemently and profusely to Commonwealth’s “Exhibit 1,” these objections should suffice to protect against further testimony and comment generated by the admission of this Exhibit. The record shows the appellant objected on some occasions, but not on others, at the continuing effort to label him a pedophile, and to using this characterization to bolster and support the case against him.
In the context of this case using the terms against the accused was error, and we need not decide when and where there was sufficient objection because we have already held the case must be reversed because the use of Commonwealth’s “Exhibit 1” was prejudicial error. However, because there may be a new trial, we must address their use.
The terms “pedophile” and “pedophilia” were used here improperly for three reasons:
1) The proof the police officer was qualified to provide expert testimony on the subject was woefully inadequate.
2) No foundation was laid to establish the officer’s testimony was “a subject matter appropriate for expert testimony (Lawson, Kentucky Evidence Law Handbook, § 610(B)).” It fails the “Frye ” test, Frye v. United States, 293 F. 1013 (D.C.Cir.1923), which requires proof that the subject matter of expert testimony has attained the general acceptance of the scientific community.
Recently, our Court has been confronted with a series of cases involving a similar problem, wherein the Commonwealth attempted to bolster the testimony of the alleged victim with profile evidence regarding the so-called “child sexual abuse accommodation syndrome”: Bussey v. Commonwealth, Ky., 697 S.W.2d 139 (1985); Lantrip v. Commonwealth, Ky., 713 S.W.2d 816 (1986); Hester v. Commonwealth, Ky., 734 S.W.2d 457 (1987); and Mitchell v. Commonwealth, Ky., 777 S.W.2d 930 (1989). We reversed all of these cases because the evidence was insufficient to admit the evidence under the “Frye’’ test:
“There was no evidence that the so-called ‘sexual abuse accommodation syndrome’ has attained a scientific acceptance or credibility among clinical psychologists or psychiatrists. Even should it become accepted, ... there would remain the question of whether other children who had not been similarly [sexually] abused might also develop the same symptoms or traits.” Lantrip, supra, 713 S.W.2d at 817.
Profile evidence and argument to establish the accused as a pedophile, as a person with a propensity to sexually molest children, is but the opposite side of a coin stamped on the other side “child sexual abuse accommodation syndrome.” This “pedophilia” profile appears to be nothing more than the attempt at an end run around the principles that controlled our decisions in Bussey, Lantrip, Hester, and Mitchell. It will require much more by way of scientific accreditation and proof of probity than we have in the record before us for this testimony to attain admissibility.
3) The only conceivable purpose the terms “pedophile” and “pedophilia” served here was to characterize the mental state of the appellant as a person with an abnormal propensity to engage in “sexual activity with children.” This was the framework *654in which Officer Curtis defined the term, and the major thrust of the prosecutor’s opening statement and closing argument as well as the officer’s testimony. In Commonwealth v. Craig, Ky., 783 S.W.2d 387, 389 (1990), we held that evidence “Ramona Craig was suffering from [the battered wife] syndrome at the time of the shooting of George Craig” was not evidence of a “mental condition,” and we overruled Commonwealth v. Rose, Ky., 725 S.W.2d 588 (1987) to the extent the Rose case held otherwise. The Majority in Craig never explained why or how it reached this result. Three justices dissented from this portion of the Craig opinion, Vance, J., stating:
“Call it what you will, this is a condition of the mind.... used to support a plea of self-defense.
[[Image here]]
... I certainly do not believe that [‘the social worker’] should have been permitted to make the diagnosis that the appel-lee was suffering from such a state of mind.” 783 S.W.2d at 391.
Concepts such as a “battered woman syndrome” in the Craig and Rose cases, or a “pedophile” in the present case, have no conceivable bearing on a criminal case except as they bear on the accused’s mental condition at the time of the alleged offense. The proposition that they should be used as evidence to convict or acquit without further testimony from an expert qualified in the field positively establishing that the condition is a recognized scientific entity, and then tying the accused to this mental state, is indefensible. Commonwealth v. Craig was in error, and is overruled to the extent it has overruled Commonwealth v. Rose on this point. In the present case, in the event of a retrial no evidence should be admitted, and no argument permitted, characterizing the appellant as a “pedophile,” or suggesting that he suffers from “pedophilia,” unless there is proof from an expert on the subject qualified to express an opinion about the appellant’s mental condition.
The conviction and judgment in this case are reversed, and the case is remanded for further proceedings consistent with this opinion.
COMBS, LEIBSON and SPAIN, JJ., concur.. What "pedophile" and "pedophilia" describe, if anything, in the standard nomenclature of psychiatry is nowhere provided in this case. For what it is worth, Webster’s Ninth New Collegiate Dictionary (1983 ed.) defines "pedophilia” as "sexual perversion in which children are the preferred sex object,” and "pedophile” as "one affected with pedophilia.”
