But according to the Chicago Tribune, DeSalvo told the police about the victims, their belongings, their apartments, and their furniture — details that no one else could have known.
Before he confessed, he also asked the prison psychiatrist a strange question about how society might react to a person who was thought to have destroyed 11 bridges when he had actually destroyed 13.
The psychiatrist explained what he believed his question meant.
"In the human anatomy, the neck is a bridge, the connection between a center of great activity, the brain, and the outlying body," he said. "What DeSalvo was saying was that he had destroyed 13 people — the women — by destroying their necks.''
According to The Daily Beast, although many people point to the details DeSalvo got wrong, investigators were shocked by how much of it he had remembered since he was presumed to have raped hundreds of women in their homes.
