Details: Thirteen-year-old Jessyca Mullenberg was a high school student in Stevens Point, Wisconsin and the daughter of Monica Bourget and Dale Mullenberg. After they divorced, she attained primary custody while he received weekend visitation. Unbeknownst to Jessyca, she became the obsession of thirty-seven-year-old Steven Oliver, who worked as an aide at her school. He was so infatuated with her that he followed her when she and her family moved to different cities in Wisconsin. He eventually bought a place across the street from Dale when he settled down in Eau Claire.
On September 16, 1995, Jessyca was visiting Dale when Oliver told her that a publisher was interested in a story that she wrote. However, this was a deception he used in order to abduct her. They have not been seen since.
Suspects: Oliver was believed to be responsible for Jessyca's disappearance. He reportedly became obsessed with her after working as an aide at her school. He often lavished her with expensive gifts and always drove her and his son to visit their respective parents. Monica tried to get a restraining order against him but was told she could not do so since he had not done anything criminal against her.
Extra Notes: This case first aired as a part of a Special Bulletin on the December 1, 1995 episode, along with Ronald Bax. It was also profiled on America's Most Wanted and I Survived.
Results: Solved. A motel manager recognized Oliver after seeing him on America's Most Wanted. On December 28, 1995, he was arrested and Jessyca was located alive and reunited with her family. They were living in the motel as father and daughter. During their time together, he held her captive in the rooms and repeatedly abused her both physically and sexually. He was later sentenced to forty years in prison for his crimes.
Jessyca continues to tell her story of her abduction as a counselor and tries to help people with similar experiences. She is now married, has two children, and goes by Jessyca Christianson.
