A 57-year-old St. Johns County man was arrested Friday on charges of capital sexual battery and sexual battery on a victim between the ages of 12 and 18.
Robert Kunz was being held in the St. Johns County jail without bond.
He is charged with committing sexual battery on a child younger than 12 and again on that same child while older than 12.
Deputies said the instances happened at several locations in St. Johns County over the course of six years.
Detectives began the investigation last Thursday after the victim, now in her teens, disclosed the sexual abuse to the Department of Children and Families, deputies said.
Detectives are continuing the investigation.
