Less than two months later, on April 7, Dahmer encountered a 19-year-old named Errol Lindsey walking to get a key cut. Lindsey was heterosexual. Dahmer lured Lindsey to his apartment, where he drugged him, drilled a hole in his skull and poured hydrochloric acid into it. According to Dahmer, Lindsey awoke after this experiment (which Dahmer had conceived in the hope of inducing a permanent, unresistant, submissive state), saying: "I have a headache. What time is it?" In response to this, Dahmer again drugged Lindsey, then strangled him. He decapitated Lindsey and retained his skull; he then flayed Lindsey's body, placing the skin in a solution of cold water and salt for several weeks in the hope of permanently retaining it. Reluctantly, he disposed of Lindsey's skin when he noted it had become too frayed and brittle.
