Mary Katherine "Mary Kay" Fualaau , was an American sex offender and teacher who pleaded guilty in 1997 to two counts of felony second-degree rape of a child. The child, Vili Fualaau, was 12 years old when she initiated their sexual relationship. He was her sixth-grade student at an elementary school in Burien, Washington. While awaiting sentencing, she gave birth to Fualaau's daughter. With the state seeking a 7.5 year prison sentence, she reached a plea agreement calling for six months in jail with three months suspended and no contact with Fualaau for life, among other terms. The case received national attention.
