In re K.B.Annotate this Case
After a police officer scanned Instagram and saw photos of appellant (then on probation) and others in possession of firearms, officers performed a probation search and found loaded firearms. The San Francisco County District Attorney filed a petition charging appellant, age 17, with two counts of possessing firearms. The juvenile court sustained the petition. The court of appeal remanded for the limited purpose of supplying the maximum term of confinement and custody credits, mandatory information in the dispositional order that was omitted, but otherwise affirmed. The court rejected arguments that the evidence did not support the juvenile court’s finding and that the court erred in admitting incriminating photographs over his objection on the ground they were not properly authenticated and erred in allowing a police officer to give expert testimony about the make and model of the recovered firearms without first qualifying him as an expert.
