Charles Kenyon’s resignation followed an incident reported at a junior varsity game on Oct. 15. Ray Michael Williams, the father of a senior on the team, said his son was volunteering at a concession stand when Kenyon spoke to a recent graduate who had joked about the burgers being grilled.

Williams said Kenyon responded, “This is for whites only.” He also said the coach then told his son to play guard for the band. When the student asked what Kenyon meant, Williams recounted, the coach referred to color guard and pointed to his own skin.

Three parents working at the concession stand heard the remarks, Williams said. One contacted him by email that Sunday. Williams said his son had not raised the incident because he understood the coach to be joking.

Williams said he contacted the superintendent’s office and the school athletic director the next morning, then spoke with the district’s human resources director. The director apologized and opened an investigation, according to Williams.

In an email notifying families of Kenyon’s departure, the school principal said the resignation came as the district investigated reports of “racially derogatory language.” The departure also affected families of students whose classes would have a new teacher, the email said.

Williams said the comments should not be dismissed. “It’s not acceptable,” he said.

The available information does not include the district’s findings or a response from Kenyon.
