Audio of phone conversations reportedly between former Centennial High School principal Dr. Frank Brown and a woman he had a relationship with were obtained by Nashville's News 2 from the Williamson County School District on Wednesday.
The conversations appear to have taken place using Brown's office phone during school hours.
The recordings and some emails the pair traded were included in an investigation that led to Brown's resignation as principal on Tuesday.
It is alleged that Brown began an inappropriate sexual relationship with the woman when she was a student at McGavock High School and he was a teacher about a decade ago.
In a conversation recorded October 5, the pair appeared to be planning a rendezvous following Centennial High School's homecoming football game against Cane Ridge High School.
"I'm going to be pretty tied up at a football game, but if you come, then I might be able to meet you up here," Brown reportedly said. "Where in the school?" the woman asks.
"I don't know?" he replied, "my office?"
In another exchange, the woman talks about alleged sexual encounters she had with Brown when he was working at McGavock High School.
"It always makes me bring back to those moments we used to have in your office and your classroom," she said.
The woman's husband turned over the recordings, as well as emails the pair exchanged to Williamson County School officials.
Attorney Bryan Pieper represents Dr. Brown. He emailed Nashville's News 2 and said all the allegations against Dr. Brown are lies.
"The allegations against Dr. Brown are absolutely false and outrageous," he wrote. "Dr. Brown has never had an inappropriate relationship with any student in any school where he has worked."
Pieper said Dr. Brown acknowledges having a brief relationship with the woman several years ago.
He said that was after the woman graduated from high school and was in her early 20s.
"He is distraught that Williamson County School System did not even bother to conduct the slightest investigation or due process, opting instead to simply accept the story from a source that is far from credible," he wrote. "The story is manufactured. The audio recordings are fake. The emails are fake. "
He continued, "We are in the process of preparing a more complete telling of the story, which will be provided to the school system in an effort to avoid legal action, and Dr. Brown requests that everyone withhold judgment until that story has been told." Williamson County Sheriff's Department said it will not pursue criminal charges against Dr. Brown in connection with the allegations.
Dr. Brown began working in the Williamson County School District in 2007 as the assistant principal of Independence High School and later as principal at Heritage Middle School.
Brown became the principal at Centennial High School in 2010.
Officials said former Centennial assistant principal Sandra Joyner will fill the position.
Parents were notified of Brown's resignation via phone calls Tuesday night.
Prior to his career in Williamson County, Brown was a teacher at La Vergne High School from 1994 to 1996.
Rutherford County Schools' spokesperson James Evans told Nashville's News 2 the district has no record of any complaints against him.
