(WAFF) - We've learned more about how 15-year-old Elizabeth Thomas and Tad Cummins communicated before they disappeared.
Maury County District Attorney Brent Cooper says the two were writing emails, not sending them, but instead saving them as drafts.
Cooper explains, one would write a message as a draft. Then, the other would log in and read the e-mail, they would delete it, and then write another e-mail saved as a draft.
The two used Cummins' school email.
Cooper wouldn't detail what was said in the emails, only that they were inappropriate.
"To me, it definitely shows that Mr. Cummins knew that these communications were inappropriate, otherwise, why go to these lengths to keep them hidden?" said Cooper. "They took extraordinary measures to try to conceal all those communications."
On Sunday a new video was released that reveals the voice of Thomas for the first time since she was kidnapped. The roughly one-minute video was posted by Wayne County Now.
"Please share this video in hopes that someone recognizes her voice," said a statement included with the video, which was provided by Elizabeth's family. "Appearances can be altered but voices are indistinguishable."
In the video, Elizabeth can be seen patiently instructing an older brother on how to sew a Confederate flag.
We will continue to follow this story, and bring you the latest.
