Mary Kay Letourneau was a married mother-of-four when she began a sexual relationship with Vili Fualaau, a sixth grade student. She was 34. He was only 12.
In 1997, their illicit affair led to her being sentenced to seven and a half years in jail for second-degree rape of a child, a crime for which Letourneau believes she was wrongfully imprisoned for.
During this time, she was required to have no contact with her former-student but managed to thwart the system using a number of bizarre methods.
According to the Mary Kay Letourneau episode of Barbara Walters Presents American Scandals, the teacher-turned-sex-offender even resorted to smuggling messages in bottles of breast milk.
The couple, of course, share two daughters Audrey, who was born while her mum was out on bail in 1997, and Georgia, who was born in 1998 while Mary was in prison.
"Mary stayed in touch with Vili in a lot of different ways," author Gregg Olsen, who has covered the case, told Walters. "One way was to send out messages in the milk bottles that she was — [producing] milk in prison for her babies, so she put little notes in the caps and they went out."
"She sent audiotapes out," he added. "She had prisoners make phone calls for her, because she could not contact him [Fualaau] directly."
WATCH: Mary Kay Letourneau and Vili Fualaau separate, but it's not what you think. Post continues...
In 2005, Letourneau and Fualaau were married in front of 250 guests. However, Fualaau filed for legal separation in 2017 after 12 years of marriage.
Fualaau explained he filed for divorce due to a new business venture -- he's hoping to become a distributor for Cigaweed marijuana cigarettes, which requires a license.
"It's not necessarily what you think," he told Radar Online. "Everything is fine between us."
"All the rumours that you hear between us. It's fine," he said. "Of course [we are still in love]. A piece of paper doesn't break someone's feelings!"
"If I decide to be a part of it I have to be licensed and I have to be vetted and so does a spouse. She has a past. She has a history."
Letourneau is now 56, and Fualaau, 34.
