While attending Arizona State University, Mary Kay met and married fellow student Steve Letourneau. They had four children. The first, Steven Jr., was conceived while she was enrolled at Arizona State University. She says she was not in love with Steve Letourneau and married him after being urged to by her parents. Mary Kay Letourneau and her husband left the university and moved to Anchorage, Alaska. After a year in Alaska, her husband was transferred to Seattle, Washington and she gave birth to their second child, Mary Claire. Mary Kay attended night classes at Seattle University and graduated in 1989. Later, she began teaching second grade at Shorewood Elementary School in the Seattle suburb of Burien, Washington.
The Letourneaus' marriage reportedly suffered from financial problems and extramarital affairs by both husband and wife. Her attorney, former neighbor and friend David Gehrke said that she was "emotionally and physically abused by her husband" during the marriage and twice "went to the hospital for treatment, and police were called," although no charges were ever filed. She gave birth to two more children, son Nicholas and daughter Jacqueline. In May 1999, while incarcerated for child rape, Mary Kay divorced Steve Letourneau and surrendered custody of their four children to him.
