A 13-year-old boy is facing eight years in juvenile hall because of an errant gum wrapper.

Jeffrey Figueroa says he was waiting in line for a gym locker on his first day at Walnut Creek Intermediate School in September when an accident unfolded. He says he rolled a gum wrapper around his finger, put it in his mouth and spit it out. The wrapper hit a fellow student in the eye and the injured boy had to have surgery.

Jeffrey says he has apologized to the other boy.

The Contra Costa County District Attorney´s office has convicted him on felony charges of battery and mayhem. The charges carry up to eight years in a California Youth Authority facility.

Jeffrey is under house arrest as he awaits sentencing – which is scheduled for June 6th.
