MONROE - Charges were formally filed Friday against a New Glarus resident accused of molesting an underage girl for three years. Matthew Thomas Ingham, 31, faces a Class B felony count of first-degree sexual assault of a child, a Class C felony count of repeated sexual assault of the same child and a related Class C felony.
