WASHINGTON (AP) — The Supreme Court has turned away a free-speech appeal from a former school lunch server in Minnesota who was charged with sexting a 15-year-old student.

The justices did not comment Tuesday in allowing the criminal case against Krista Muccio to proceed.

Muccio was charged with sending words and photos of a sexual nature to the student. The teen's father found them on his son's Instagram account.

A Minnesota appeals court had struck down a state law aimed at adults who use social media to lure children into sexual encounters. The state's Supreme Court overruled the lower court.
