HAMILTON, Ohio -- A Hamilton High School teacher and volleyball coach pleaded guilty Tuesday to gross sexual imposition involving a student, according to the Journal-News .
Hilary Dattilo, 30, could face up to 18 months in prison for the crime, which police said involved a female student and took place off school property in fall 2017.
Parents reported the "possible inappropriate relationship" to a school staff member, at which point police began their investigation.
Dattilo was charged in January with sexual battery and contributing to the delinquency of a minor, at which point she surrendered herself to the police.
