Knox County General Session Court Supervisor April Mayes, who submitted a resignation letter earlier this week, said her last day on the job will be Dec. 18.

In a brief interview with WBIR 10News on Wednesday, Mayes said she's stepping down to take a new job. She said didn't say where.

However, Mayes said her resignation has nothing to do with the problems in the overall operations of the Knox County Criminal Court Clerk's Office.

Mayes oversees the department mostly faulted by the district attorney's office, the sheriff's office and county judges for a series of errors that have led to wrongful arrests, cases set aside due to errors and resident temporarily losing their right to vote.

In late November, a Seymour teenager who says he was wrongfully arrested earlier in the month because of a mistake made in the Knox County Criminal Court Clerk's Office sent the county's law department a demand letter, seeking $50,000 in damages.

The mistakes, first reported in a WBIR 10News investigation, appear tied to poor training, outdated information and her refusal to cooperate with other county departments. Court workers often enter the wrong data into the records management system, lose crucial paperwork and provide defendants, prosecutors, and authorities with bad information.

The Criminal Clerk's Office is responsible for General Sessions Court, Criminal Court and the Fourth Circuit Court.

Knox County Criminal Court Clerk Joy McCroskey on Wednesday declined to comment.

"I have no answers for you," she told a WBIR reporter.

Mayes, who earned $62,400, was hired in August 1997.
