He [Jeffrey Dahmer] rarely talked to his defending counsel [Gerald Boyle], but sat compliantly between Wendy Patrickus and Ellen Ryan [Boyle’s associates] day after day, answering monosyllabically when either addressed him. These two young ladies in fact knew him very well by now. They had seen him on a regular basis for over six months and had shared the gradual revelation of his iniquity. They had talked to him longer and more often than anyone else. […]
It took a long time for she and Miss Patrickus to gain Dahmer’s confidence, or rather his relaxed acceptance of them. At the beginning, he had behaved as someone totally unfamiliar with human contact. He did not know how to find it or deal with it, especially with two young women. He was docile, polite and accommodating, but in no way socially forthcoming. They felt that he was capable of friendship, and had never been offered it before. So they preserved, quite apart from the demands of the job, in getting him to relax without bullying. After six months they conceded that he was “a nice guy” […].
He would pay gracious, slightly embarrassed compliments, such as (to Miss Patrickus) “You look nice today”, or (to Miss Ryan) “That’s a snappy necklace you’re wearing.” He was like a novice in learning the social graces. Ellen and Wendy said it was “lovely to see him open out and relate.” For his part, Jeff Dahmer told them "You know, you are the closest friends I have had in my entire life."
