Jill Cummins, the wife of Tad Cummins, said that her husband admitted to sleeping with Elizabeth Thomas, his teenaged former student, while they were on the run.

In an interview with Inside Edition, Jill said that she asked her husband about his relationship with the teenager. "I said, 'Did you sleep with her?' And he said, 'Yes, I did,'" she narrated in the interview.

"I didn't want any details, but I knew the truth. I just wanted to hear it from him to me," she continued. She also said that her husband contacted her via a phone call from jail. He asked for her forgiveness and told her he still loved her.

"I of course went into a rage of, 'Do you know what you've done to me? Do you know what you've done to your girls and your grandchildren?' He pretty much just over and over said, 'I'm sorry'," she said. She admitted that she has not talked to him since then, although he continues to call from jail.

The publication revealed that Jill filed for divorce from her husband after his disappearance with Thomas. Meanwhile, the teen is currently in a mental health institution following the incident. While she has yet to find her way back home, the family has released a statement through their attorney that she was "healthy" and "safe."

Prior to the rescue, the investigators discovered that Cummins did his research before running away with Thomas. According to The Tennesseean, the former teacher went online to search for "teen marriage," as well as for information on whether his vehicle, a Nissan Rogue, can be tracked by the authorities. The investigation also revealed that Cummins may have conditioned the mind of Thomas to convince her to run away with him.

Meanwhile, Griffin Barry, who was the caretaker of the California cabin where Cummins and Thomas took refuge in, stands to gain $1,000 for the tip he gave the police, according to AL.com. In an interview with Inside Edition, Barry said that he initially did not recognize the two, but when he did, he called the police to report the sighting. His report was instrumental to the authorities finding the disgraced teacher and his former student.

Thomas faces 10 years up to life in prison for his abduction of Thomas, a minor.
