WILLIAMSTON — Authorities say a middle school’s parent-teacher organization president has been charged with criminal sexual conduct with a minor over her relationship with a 14-year-old boy.

Investigators said 33-year-old Jamye Sanders had sex with the boy over about six months this year, with some of the encounters taking place at Palmetto Middle School.

Police say the boy was friends with Sanders’ teenage daughter.

Investigators say Sanders also was a substitute teacher.

Sanders’ lawyer says she is cooperating with police.
