Dahmer probably was a sensor, going by his childhood family videos. He was really engaged in his physical surroundings, wanting to touch and feel everything, according to his father. Actually his crimes might have been a reaction to his growing intuition, he said himself around age 15 he started to have compulsive fantasies about kidnapping a hitchhiker, having his way with them. The fantasies would be burgeoning Ni and their content would reflect what Dahmer was familiar with, the concrete world. He also strangled many men and beat one to death without intending it, which points to his physical strength. He didn't seem outwardly violent, but I think this is a sign of what Jung describes as identification with the persona (superego), the id (shadow) becomes correspondingly unconscious and vicious, acted out in private.
