25-year-old Kyron Corpuz of Lihue was sentence to 10 years in prison on Thursday for sexually assaulting a child on more than one occasion between 2012 and 2016.
Corpuz was arrested on March 14 after the juvenile victim reported the assaults to school counselors.
Corpuz pleaded no contest on April 7 to two sexual assault charges - one count each in the second and third degrees.
"Our thoughts are with the victims and survivors of this defendant's crimes and we hope they are able to move forward in the lives knowing that this defendant will be in prison for a long time. Child sex assault remains a problem in our community and we will not rest in our efforts to achieve justice in these cases," prosecuting attorney Justin Kollar said.
