The Columbus School for Girls fired its German teacher Dec. 23 after he admitted to committing sexual abuse against a student almost 50 years ago when he taught in the Westerville school district.

Police told CSG officials two former Westerville students, now in their mid-60s, had accused Ronald Nocks, 80, of Westerville of inappropriate sexual contact when he was their high school teacher in the late 1960s.

Nocks was the head of Westerville High School's theater department from 1963 through 1984. Westerville High School became Westerville South in the 1975-76 school year with the opening of Westerville North High School.

Westerville city spokeswoman Christa Dickey said Westerville police opened an investigation but no charges have been filed, so they have no further information or comment on the case. Because of the statute of limitations, it is unclear whether any criminal charges could be brought against Nocks.

Westerville City School District administrators met with the two accusers Dec. 18, after they requested a meeting, said Greg Viebranz, the district's executive director of communication and technology. The district called police immediately after hearing the men's stories, and they went through Nocks' personnel file to be sure there were no other red flags from his time at Westerville schools.

The district asks anyone with further information about Nocks to contact Westerville police.

Jennifer Ciccarelli, CSG's head of school, sent a letter Dec. 24 to parents and staff, informing them that Nocks had been put on administrative leave Dec. 21 during the investigation, and his employment was terminated Dec. 23 after he admitted to police that the allegations were true in the case of one of the two accusers.

She said Nocks passed a background check when he was hired in 2007 at CSG and again in 2013.

"Let me stress that, at this time, we have absolutely no indication that Mr. Nocks ever engaged in any inappropriate behavior with CSG students or staff," Ciccarelli's letter said. "Such behavior, regardless of when it occurred, makes Mr. Nocks unfit to teach at CSG."
