SEATTLE — Mary Kay Letourneau, the infamous teacher who married her former sixth-grade student has died from stage four cancer at the age of 58.

Letourneau married and had two children with Vili Fualaau who was a precocious 12-year-old in her class at Shorewood Elementary in Burien, a south Seattle suburb.

Letourneau pleaded guilty in August 1997 to two counts of second-degree rape with a student who was 13 at the time. (She was 34, married and had four children) She later married the student, Vili Fualaau in 2005—after serving her seven-year prison sentence. He was 22.

She knew her actions were wrong morally and professionally but took the risks in part because of her diagnosed “hypomania,″ a type of bipolar depression, her attorney told local media.

Fualaau and Letourneau had previously characterized their relationship as one of love, and even wrote a book together — “Un Seul Crime, L’Amour,” or “Only One Crime, Love.” Their story was also the subject of a USA Network movie, “All American Girl.”

King County court records show Fualaau asked the court for a legal separation from Letourneau on May 9, 2017. They divorced last year.
