Following a bench trial for the charges of battery and violating the Georgia Street Gang Terrorism and Prevention Act,1 A. G., A. M., S. W., and D. R. (the “juveniles”) appeal their adjudication of delinquency, contending that the evidence was insufficient to support the verdict against them and that the trial court erroneously based its findings on evidence not properly in the record before it. These cases have been consolidated on appeal. For the reasons set forth, we reverse.
In reviewing an adjudication of delinquency, this Court construes the evidence and all reasonable inferences therefrom “in favor of the juvenile court’s adjudication to determine if a reasonable finder of fact could have found, beyond a reasonable doubt, that the juvenile committed the acts charged.”2 In reviewing such cases, we neither weigh the evidence nor determine witness credibility.3
So construed, the record shows that following a pep rally in the Tattnall County High School gymnasium, T. W., a student, was surrounded by four other students, A. M., S. W., D. R., and A. G., who took turns striking him around his head. Sergeant Jones, an officer on duty at the school, searched all four students within an hour and a half after the incident. A notebook was found on A. M. that had “G-ville 912” written on the outside cover. A. M. testified that the writing was not gang-related and was short for his town, Glenville, and its zip code. However, Jones, who was certified by the trial court as an expert on gangs, testified that “G-ville 912” was written in a style associated with gangs. A bandana with a currency print was found on A. G., and purple bandanas were found on S. W. and D. R. Jones concluded that the bandanas were gang-related because of the *166particular way they were folded and instructed the court that the different patterns could identify member rankings within a gang. However, Jones also noted that he had not seen purple bandanas identifying with gang membership at the school before, and that bandanas signifying gang membership at the school “are normally red, white, or black.” Additionally, Jones testified that he did not know the current name of any gang within the school or its members because they change names so often.
None of the juveniles challenge their adjudication of the predicate offense — battery. Rather, they contend that the state failed to show that they were associated with an organization that fits the definition of “criminal street gang.” All four juveniles were charged with violating OCGA § 16-15-4 (a), which makes it unlawful for persons associated with a “criminal street gang” to engage in “criminal gang activity” by committing certain enumerated predicate offenses, including battery.4 5A “[cjriminal street gang” is defined as a “group of three or more persons associated in fact, whether formal or informal, which engages in criminal gang activity.”6
The statute clearly contemplates that the existence of such an organization, and that its members are “associated in fact,” “may be established by evidence of a common name or common identifying signs, symbols, tattoos, graffiti, or attire, or other distinguishing characteristics.”6 However, such evidence, without more, is insufficient to prove that the juveniles are members of a criminal street gang.7
The only evidence presented by the state that the four juveniles in this case are members of a criminal street gang was the testimony from Jones that the three bandanas found on A. G., S. W., and D. R. were indicia of gang membership and that the writing on A. M.’s notebook was written in a style associated with gangs. Giving credence to Jones’ testimony, as we must,8 this evidence is insufficient to prove beyond a reasonable doubt that the four juveniles were members of a criminal street gang. Every case by this Court affirming convictions under OCGA § 16-15-3 (2) has included more than merely a single common identifying sign to prove a defendant’s membership *167in a criminal street gang. In In the Interest of C. P.,9 a juvenile defendant was found to be part of a criminal street gang based upon officer testimony that C. P. was wearing colors associated with the Bloodz gang and that the pieces of paper he was carrying depicted symbols and codes associated with the Bloodz and the 55 Mafia. In addition, C. P. admitted to being a gang member and that the scars on his hands were a result of removing a gang tattoo. In In the Interest of X. W.,10 the juvenile defendant was found to be a member of a criminal street gang based upon evidence that he had several copies of the Bloodz’ “Book of Knowledge” in his possession, that he instigated a fight with a rival gang to help an uninitiated classmate join the gang, and that he had gang graffiti written on his desk. In In the Interest of D. M,11 evidence of membership in a criminal street gang included wearing a black bandana, a color associated with a particular gang, during a drive-by shooting and the juvenile’s admission to a detective that he was a member of that gang. In In the Interest of A. D.,12 the investigating detective “easily established” that both juveniles were members of related gangs because they admitted that they were members, both had tattoos associated with their gangs, and the detective had previously “documented” the juveniles as being gang members. In Lopez v. Stated,13 sufficient evidence to support a conviction included witness testimony, including that from a former gang member, and numerous photographs showing that defendant was a member of a gang.
Here, there was no evidence beyond the bandanas and a notebook to link the juveniles to membership in a criminal street gang. Jones did not describe the “G-ville” gang or testify about any of their activities, let alone their involvement in any criminal activities. To be a member of a “criminal street gang,” the group or organization must be “engage[d] in criminal gang activity as defined in paragraph (1)” of OCGA § 16-15-3. To sustain a conviction, the state must prove that the criminal gang activity or plans for its continuation was ongoing at the time of the commission of the indicted offenses; “in other words, the commission of an enumerated offense by the defendant is not *168itself sufficient to prove the existence of a ‘criminal street gang.’ ”14 Our Supreme Court has held that to hold otherwise, “the nonsensical result would be that a member of any legitimate group could violate the Act merely by committing an enumerated offense.”15 Accordingly, the battery committed in this case cannot serve as sufficient proof of the necessary gang activity.
Decided July 11, 2012 Reconsideration denied July 27, 2012. Melissa E. Lawrence, Cheryl C. Quick, Karen L. Mead, William O. Cox, for appellants. Tom Durden, District Attorney, Johnathan C. Gaskin, Assistant District Attorney, for appellee.Because the state failed to establish that a “criminal street gang” was involved in the battery, we need not address appellants’ remaining enumerations: that the state failed to establish a nexus between the battery and an intent to further street gang activity, that the trial court relied upon impermissible hearsay evidence, and that the trial court considered evidence that was never introduced in the record in the final orders. The judgments on the counts charging criminal street gang activity are reversed in all four cases.
Judgments reversed.
