DUNEDIN — A 21-year-old Dunedin man has been arrested based on allegations that he molested a girl over a period of eight years, beginning when she was 4.

Zachary Watton was charged Tuesday with two counts of lewd and lascivious molestation, the Pinellas County Sheriff's Office said.

Detectives began investigating after a girl, now 14 years old, told her parents that Watton touched her inappropriately from the time she was 4 years old until she was 12, according to the Sheriff's Office.

On Tuesday, detectives said, Watton came to the Sheriff's Office and "admitted to the crime" during an interview.

The investigation continues.
