We granted a writ of certiorari to review the Court of Appeals’ opinion in State v. Fletcher, 363 S.C. 221, 609 S.E.2d 572 (2005). We reverse.
FACTS
Petitioner, Henry Fletcher, was indicted for homicide by child abuse relating to the death of nine-month-old Jaquan Perry. Jaquan was the son of Fletcher’s live-in girlfriend, Ikeisha Perry. On the afternoon of September 21, 2000, Perry and Fletcher transported Jaquan to Palmetto Richland Memorial Hospital at approximately 1:15 p.m. According to Perry and Fletcher, the child had been fine that morning, so they took him on errands and to his brother’s dental appointment. As they were leaving the dentist office, Fletcher noticed the soft spot on Jaquan’s head was not moving so Perry checked and could not find a heart beat. Neither Fletcher nor Perry had noticed anything wrong with him prior to this time. However, both Fletcher and Perry told police Jaquan had fallen off a mattress onto a hardwood floor that morning. Although he seemed sleepy, they thought he was otherwise okay.
Dr. Robert Hubbird, the Pediatric ICU physician who first saw Jaquan at the hospital, testified that when he first saw him, Jaquan was in full cardiopulmonary arrest, his heart was not beating, and he was not breathing. Jaquan was resuscitated several times but was ultimately pronounced dead at 4:20 p.m. Dr. Hubbird testified Jaquan’s abdomen was severely distended and protuberant, and that both his liver and bowel were injured. The bowel was injured so severely that it was leaking out into the abdomen and perineal cavity. According to Dr. Hubbird, both the liver and bowel were dying; the fact that he could not hear any bowel sounds meant they had been like that for days. Dr. Hubbird testified that Jaquan’s injuries were not consistent with the reports given by Perry and Fletcher, and that the injuries would have taken an extreme amount of force directly to the abdomen. Dr Hubbird opined that the injuries would not have happened from falling a few feet from a bed onto a hardwood floor. Dr. Hubbird also testified that Jaquan had multiple rib fractures *21and there were numerous bruises on his body, ranging in date from 1-10 days old. The cause of Jaquan’s death was child abuse from massive intra-abdominal injuries, massive injuries to kill the bowel, and widespread infection which killed the liver. .
Dr. Timothy P. Close, a radiologist, also testified to the injuries to Jaquan’s liver, bowels, kidneys, spleen, and that there were fractured ribs. Close testified there were numerous rib fractures, and that they were not all suffered at the same time, which was evident from the bruising, swelling, and different shading of the bones as they attempted to heal themselves. Close felt the newest fractures were anywhere from several hours to 2-3 days old, whereas some of the older ones were more likely 10-14 days old. Dr. Close likened the injuries suffered by Jaquan to injuries suffered in an auto accident where a person has been ejected at 60-70 miles per hour.
At trial, over the objection of defense counsel, the state called Carlos Jenkins, a friend and co-worker of Fletcher, as a witness to two events he had seen in the month prior to Jaquan’s death. The attorneys for both Perry and Fletcher objected, contending there was not clear and convincing evidence as to who committed those acts, nor were those acts causally related to Jaquan’s death. The trial court ruled that the “the course and conduct within a reasonable time before [Jaquan] died” was admissible. The Court also ruled it was a res gestae type situation. Accordingly, Jenkins was permitted to testify.
Jenkins testified he had known Fletcher for 4-5 years and had known Perry for only a couple of months. Over counsels’ renewed objections, Jenkins testified that approximately two weeks prior to Jaquan’s death, he had gone to Fletcher’s house (where Perry and her two children were also living) and heard the baby crying. Fletcher told him the baby was upstairs, so he walked upstairs and found Jaquan sitting in a walker in the attic, “pouring down sweat like he had just dipped him in a bathtub.” Jenkins testified he took Jaquan outside on the porch and cooled him off. Both Fletcher and Perry were home at the time.
*22Jenkins also testified that sometime in the two or three weeks prior to the attic incident, he came to the house and found Jaquan handcuffed by his feet to the bed on which Fletcher and Perry slept, so he unlocked the cuffs. Both Perry and Fletcher were home at the time. When Jenkins asked them if they were crazy, they just giggled.
Perry did not testify at trial. She did, however, give several statements to police, which were admitted in redacted form at trial. In her statements, Perry also indicated Jaquan had fallen from the bed the morning of September 21st. She comforted him, and then sat him on the sofa beside Fletcher. She and Fletcher brought Jaquan with them to run errands and, as they left the dentist’s office, she realized his heart was not beating and drove to the emergency room while Fletcher attempted CPR. Perry denied ever beating Jaquan, but admitted Jaquan had been handcuffed to the bottom of the bed in her room.
Fletcher gave several statements to police and testified at trial. In his statements to police, he indicated similarly to Perry that Jaquan had rolled oft’ a mattress in the morning, but was unharmed so they took him along on errands. He noticed Jaquan’s soft spot on his head wasn’t moving when they left the dentist’s office and discovered he didn’t appear to be breathing. They drove to the hospital while Fletcher attempted CPR, striking him in the chest a few times.
Fletcher denied ever beating Jaquan, but testified that Perry had done so a few times. He testified he had not seen Perry handcuff Jaquan to the bed, but saw him that way after he got out of the shower. He also testified that the “attic” where Perry would sometimes bring the children and hang clothes to dry was not actually an attic, but an unfinished room off of a bedroom on the second level of the house. According to Fletcher, there was an air duct right outside the “attic,” one step outside from the stairs. He testified he had never put Jaquan in the attic.
Fletcher testified that he was not at the house on Sycamore Avenue from the Sunday until the Wednesday evening before Jaquan’s death, arriving at 11:00 p.m. that Wednesday. (Jaquan died on Thursday). According to Fletcher, on the day of Jaquan’s death, after he fell out of bed, Jaquan kept trying to *23go to sleep, so he was tapping/hitting Jaquan on the bottom of his feet to keep him awake.
The jury convicted Fletcher of homicide by child abuse. On appeal, the Court of Appeals affirmed, holding, inter alia, the prior bad acts testified to by Jenkins were properly admitted pursuant to Rule 404(b), SCRE, and State v. Lyle, 125 S.C. 406, 118 S.E. 803 (1923). It held the prior bad acts had been proved by clear and convincing evidence, and that the acts were admissible to demonstrate a) a common scheme or plan of child abuse or neglect, b) intent or the absence of mistake or accident, c) as part of the res gestae of crime of homicide by child abuse and d) that, in any event, any error in admission of Jenkins’ testimony was harmless beyond a reasonable doubt given the overwhelming evidence of guilt in this case.
ISSUES
Did the Court of Appeals err in holding Jenkins’ testimony concerning the events he witnessed in the weeks prior to Jaquan’s death were admissible under Rule 404(b), SCRE and that admission of this evidence was, in any event, harmless error?
DISCUSSION
Under Rule 404(b), SCRE, evidence of other crimes, wrongs, or acts is generally not admissible to prove the defendant’s guilt for the crime charged. Such evidence is, however, admissible to show motive, identity, the existence of a common scheme or plan, the absence of mistake or accident, or intent. State v. Pagan, 369 S.C. 201, 631 S.E.2d 262 (2006); State v. Lyle, 125 S.C. 406, 118 S.E. 803 (1923). To be admissible, the bad act must logically relate to the crime with which the defendant has been charged. If the defendant was not convicted of the prior crime, evidence of the prior bad act must be clear and convincing. Id.; State v. Beck, 342 S.C. 129, 135-36, 536 S.E.2d 679, 682-83 (2000). Even if prior bad act evidence is clear and convincing and falls within an exception, it must be excluded if its probative value is substantially outweighed by the danger of unfair prejudice to the defendant. Rules 403 and 404(b), SCRE (although relevant, evidence may be excluded if its probative value is substantially outweighed *24by thé danger of unfair prejudice); State v. Gillian, 373 S.C. 601, 646 S.E.2d 872 (2007); State v. Braxton, 343 S.C. 629, 541 S.E.2d 833 (2001). The determination of the prejudicial effect of the evidence must be based on the entire record and the result will generally turn on the facts of each case. State v. Bell, 302 S.C. 18, 393 S.E.2d 364, cert. denied, 498 U.S. 881, 111 S.Ct. 227, 112 L.Ed.2d 182 (1990).
The Court of Appeals stated, without discussion, “The evidence demonstrates by clear and convincing proof the occurrence of the prior bad acts.” This was error.1 The present record does not contain clear and convincing evidence that Fletcher was the person who put Jaquan in the attic, nor does it indicate he was the person who handcuffed her to the bed.
Clear and convincing evidence is that degree of proof which will produce in the mind of the trier of facts a firm belief as to the allegations sought to be established. Such proof is intermediate, more than a mere preponderance but less than is required for proof beyond a reasonable doubt; it does not mean clear and unequivocal. Peeler v. Spartan Radiocasting, Inc., 324 S.C. 261, 478 S.E.2d 282, 283 n. 4 (1996).
Here, there is simply not clear and convincing evidence in the record that Fletcher committed the prior bad acts testified to by Jenkins. Although Jenkins testified he saw Jaquan handcuffed to the bed and in the walker in the attic, there was no evidence whatsoever introduced at trial that Fletcher was either the person who placed Jaquan in the attic, or that he handcuffed him to the bed. On the contrary, Fletcher testified that upon discovering Perry had handcuffed Jaquan to the bed, he cussed her out about it after Jenkins left. Additionally, there was no testimony Fletcher was the person who put *25Jaquan in the attic room, and he testified Perry sometimes put him there while she dried her clothes as she used it as a laundry room.
We have previously found a lack of clear and convincing evidence the defendant committed the prior bad act in question where, for example, there was no evidence the appellant had committed the prior injuries of a split lip and a swollen eye because the state offered no proof the appellant inflicted the injuries. State v. Pierce, 326 S.C. 176, 485 S.E.2d 913 (1997) (evidence of prior child abuse inadmissible where there was no evidence defendant inflicted previous injury). See also State v. Cutro, 332 S.C. 100, 504 S.E.2d 324 (evidence of prior infant deaths inadmissible where there was lack of evidence defendant was the perpetrator).
On the present evidence, there is simply no evidence, let alone clear and convincing evidence that Fletcher was the perpetrator of the prior bad acts2 against Jaquan. Accordingly, the trial court erred in admitting Jenkins’ testimony.3
Finally, the Court of Appeals held that even if admission of Jenkins’ testimony was improper, any error was harmless in light of the overwhelming evidence of guilt in this case. This holding was error.
Error is harmless beyond a reasonable doubt where it did not contribute to the verdict obtained. Arnold v. State, 309 S.C. 157, 172, 420 S.E.2d 834, 842 (1992). An insubstantial error not affecting the result of the trial is harmless where “guilt has been conclusively proven by competent evidence such that no other rational conclusion can be reached.” State v. Bailey, 298 S.C. 1, 5, 377 S.E.2d 581, 584 (1989).
There was little evidence at trial as to who inflicted Jaquan’s injuries. Although Fletcher gave a statement to police *26in which he admitted to wrestling with Jaquan, and hitting him with his elbows, and ultimately to punching him, he explained this at trial both by claiming he was being sarcastic after hours of questioning, and was utilizing the police officer’s definition of “hitting” in describing his wrestling with Jaquan. Accordingly, given that the identity of the perpetrator was the essential issue at trial, and given the dearth of evidence in the record, we simply cannot say that error in the admission of Jenkins’ testimony was harmless beyond a reasonable doubt.
This case fundamentally demonstrates why certain prior bad act testimony is inadmissible, i.e., it is used by the jury to infer that the defendant did in fact commit the crime for which he is on trial. We find the only function of Jenkins’ testimony in this case was to demonstrate Fletcher’s bad character. Accordingly, admission of this testimony was both erroneous and prejudicial.4 The Court of Appeals’ opinion is reversed.
REVERSED.
MOORE, PLEICONES, JJ., and Acting Justice J. MICHELLE CHILDS, concur. TOAL, C.J., dissenting in a separate opinion.. We are not persuaded by the state's contention that this issue is not preserved for review. During a lengthy pre-trial hearing on the matter, both counsel for Perry and Fletcher argued against admission of Jenkins’ testimony. Later, immediately prior to Jenkins’ testimony, counsel for Perry objected, raising numerous grounds, including ’’the evidence relating to the rib injuries should not come in because there was not clear and convincing evidence as to who inflicted these rib injuries. ... The same with the handcuffs and with the attic incident ..." We find the issue is sufficiently preserved for our review.
. We need not decide whether these acts, if proven by clear and convincing evidence, would otherwise be admissible under Rule 404(b), SCRE.
. Further, contrary to the trial court’s ruling, the prior acts simply do not come within the res gestae under the facts of this case Accord State v. Bolden, 303 S.C. 41, 398 S.E.2d 494 (1990). (prior acts must be so intimately connected to the crimes charged that their introduction is appropriate to complete the story of the crime charged).
. The dissent would hold the evidence is admissible to establish a pattern of child abuse and neglect, such that it is relevant to the charge of homicide by child abuse. The majority of this Court, however, has specifically rejected an identical contention under similar facts. State v. Pierce, 326 S.C. 176, 485 S.E.2d 913 (1997).
