Ordered that the order of disposition is affirmed, without costs or disbursements.
Viewing the evidence in the light most favorable to the presentment agency ( see Matter of David H., 69 NY2d 792, 793; Matter of Jonathan D., 33 AD3d 996, 997; Matter of Dan H., 26 AD3d 438), we find that it was legally sufficient to establish, beyond a reasonable doubt, that the appellant committed acts which, if committed by an adult, would have constituted the crime of attempted assault in the third degree ( see Penal Law §§ 110.00, 120.00; Matter of Alex R., 36 AD3d 922; Matter of Felix D., 30 AD3d 598; Matter of Nikita P., 3 AD3d 499), and the crime of menacing in the third degree ( see Penal Law § 120.15; Matter of Ibrahim D., 18 AD3d 659; Matter of Dwayne H., 173 AD2d 466). Moreover, in fulfilling our responsibility to conduct an independent review of the weight of the evidence ( see Matter of Hasan C., 59 AD3d 617; Matter of Victor I., 57 AD3d 779; Matter of Tanasia Elanie E., 49 AD3d 642; cf. CPL 470.15; People v Danielson, 9 NY3d 342), we nevertheless accord great deference to the opportunity of the fact finder to view the witnesses, hear the testimony, and observe demeanor ( see Matter of Daniel R., 51 AD3d 933, 933-934; Matter of Victor I., 57 AD3d 779; Matter of Robert A., 57 AD3d 770; cf. People v Mateo, 2 NY3d 383, 410, cert denied 542 US 946). Upon our review of the record, we are satisfied that the Family Court's fact-finding determination was not against the weight of the evidence ( see Family Ct Act § 342.2; Matter of Ashanti B., 62 AD3d 790; Matter of Charmaine B., 60 AD3d 672 ; Matter of Hasan C., 59 AD3d 617; Matter of Victor I., 57 AD3d 779). The evidence credited by the Family Court disproved the appellant's defense of justification beyond a reasonable doubt ( see Penal Law § 35.15; Matter of Louis C., 38 AD3d 541; Matter of Rosario S., 18 AD3d 563; Matter of Javier F., 16 AD3d 290).
The appellant's remaining contentions are without merit.
