During Jeffrey's recovery period, Dahmer noted, "He seemed smaller, somehow more vulnerable, perhaps even sadder than at any time before" (1992, p. 59). Jeff had shown symptoms of alienation after his brother's birth, as his teachers and father had noticed a difference in his personality. Dahmer observed that: “The little boy who once seemed so happy and confident was gone. He had been replaced by someone else, a different person, now deeply shy, distant, almost uncommunicative” (1994, p. 62). Jeff's first-grade teacher even had the impression that Jeff felt deep unhappiness towards him, felt neglected by his parents, and noticed how he often kept to himself on the playground. Before moving to Barberton, Ohio, Jeffrey at the age of seven, also saw his mother fall into acute depression, which forced her to be admitted to a psychiatric ward to help her cope with her serious illness.
