Lippert's kidnapping of Sue Cochran and attempted kidnappings of two other women were known as "The Love Experiment" because after taking Cochran against her will, he put her into a black booth and subjected her to behavioral modification techniques he'd read about in psychology textbooks. He attached an electrical wire to her fingers and showed her photos: If they were of himself, she got rewards. If they were of, say, a snake, she got a shock. His purpose was that she would learn to love him.
