ALEXANDRIA, Va. (AP) — A former volunteer at a Manassas middle school has been convicted of producing child pornography.

A jury at federal court in Alexandria on Thursday convicted 24-year-old David Alexander Battle II of multiple counts that carry a mandatory minimum sentence of 15 years. He will be sentenced in June.

Battle was a volunteer in the music program at Metz Middle School in Manassas.

Prosecutors say Battle would go online and pose as a young girl to entice boys to send him sexually explicit images of themselves. Evidence at trial showed Battle personally knew two of the boys with whom he chatted online.
