Commonwealth v. Foster F., No. 13-P-1427, 2014 WL 6909045 (Mass. App. Ct. Dec. 10, 2014)

Key Insight: Because the relevancy and admissibility of the Facebook messages depended on their being authored by the juvenile, the judge was required to determine whether the evidence was sufficient for a reasonable jury to find by a preponderance of the evidence that the juvenile authored them; while the evidence was sufficient to support the judge’s conclusion that the Facebook messages were authored by the juvenile, as the juvenile?s actions served as a basis for concluding that the records were authentic, the better practice would have been to instruct the jurors that, in order to consider the Facebook messages as evidence of the statements contained therein, they first needed to find by a fair preponderance of the evidence that the juvenile was the author

Nature of Case: Juvenile court matter in which juvenile was adjudicated delinquent
