MAHWAH — A 54-year-old Hawthorne resident has been charged with raping a girl for three years — starting when she was 8 years old.

Kenneth J. Mowerson III was arrested Thursday in Allendale following an investigation by the Bergen County Prosecutor’s Office Special Victims Unit and this township’s police. The allegations were first reported Tuesday to police in Hawthorne.

Authorities said Mowerson raped the girl several times from May 2013 to June 2015, when she was 11.

Mowerson was charged with first-degree aggravated sexual assault, second-degree sexual assault, second-degree endangering the welfare of a child and third-degree witness tampering.
