Relatives and friends say Stacy Peterson's disappearance was the culmination of a stormy seven-year relationship that started off sweetly but turned sinister as her husband -- 30 years her senior -- grew increasingly controlling and suspicious. He reportedly forbade her from seeing family and friends, and accused her of infidelity.
By the time Stacy disappeared, she had grown fearful of her husband and had decided it was time to end the marriage, relatives and friends said.
"She would always look over her shoulder," a family friend, Bruce Zidarich, told ABC News three years ago. "She said, 'I'm gonna tell him I want a divorce.' ... It came up more and more often."
People who knew Stacy Peterson called the latest twist in the case emotional, and said today they are just looking for closure.
"Her family and friends really need that," said family friend Jaime Holt.
