EDWARDSVILLE -- A former high school band director faces up to 15 years in prison now that he's admitted having inappropriate sexual contact with one of his students.
Thirty-six-year-old Matthew Lang of Godfrey pleaded guilty Tuesday in Madison County to one count of criminal sexual assault. That involved consensual sex with a 16-year-old band member at Alton High School.
As part of a plea deal, prosecutors plan to drop three other counts.
A prosecutor revealed in court that the student's parents suspected inappropriate contact between their daughter and Lang after discovering suggestive e-mails. The girl later admitted the affair and wore a wiretap investigators used to implicate Lang.
Lang was charged in August and resigned two months later.
