November 23, 1973, was the day Benson Selberg last saw his wife, Jennifer, leave the house. At that point in time, he thought that she had gone back to her parents' house.
However, when Jennifer's parents had not seen her after five days, and she could not be contacted, the police were called.
In 1979, the police categorized Jennifer's case as a major missing persons case. To this day, Jennifer's missing case report was still on the main page of the National Missing Persons Coordination Center's website.
As their children's pictures were placed together with Jennifer's, the parents, who had been closely monitoring the National Missing Persons Coordination Center's website daily for the past few days, knew who Jennifer was and hence, knew who Benson was after hearing his words.
