DECISION ORDER
ORDERED that the appeal from so much of the order of disposition as placed the appellant in the custody of the New York State Office of Children and Family Services for a period of 18 months is dismissed as academic, without costs or disbursements, as the period of placement has expired ( see Matter of Wanji W., 305 A.D.2d 690); and it is further,
ORDERED that the order of disposition is affirmed insofar as reviewed, without costs or disbursements.
The appellant's contention that the evidence was not legally sufficient to support the Family Court's finding that she committed acts which, if committed by an adult, would have constituted the crimes of assault in the second degree, menacing in the second degree, and criminal possession of a weapon in the fourth degree, is unpreserved for appellate review ( see Matter of Bomani L., 300 A.D.2d 586, 587). In any event, viewing the evidence in the light most favorable to the presentment agency ( see Matter of Frank C., 283 A.D.2d 643, 643-644), we find that it was legally sufficient to support the determination made in the fact-finding order. Moreover, resolution of issues of credibility, as well as the weight to be accorded the evidence presented, are primarily questions to be determined by the trier of fact, which saw and heard the witnesses. Its determination should be accorded great weight on appeal and should not be disturbed unless clearly unsupported by the record ( see Matter of James B., 262 A.D.2d 480, 481). Upon the exercise of our factual review power, we are satisfied that the determination was not against the weight of the evidence ( cf. CPL 470.15).
