Dahmer committed his first murder in 1978, three weeks after his graduation. At the time he was living alone in the family home in Bath. On June 18,Dahmer picked up a hitchhiker named Steven Mark Hicks, who was almost 19.Dahmer lured the youth to his house on the pretext of the two young men drinking alcohol together. Hicks, who had been hitchhiking to a rock concert at Chippewa Lake Park, Ohio, agreed to accompany Dahmer to his house upon the promise of "a few beers" with Dahmer as he had the house to himself. According to Dahmer, the sight of the bare-chested Hicks standing at the roadside stirred his sexual feelings, although when Hicks began talking about girls, he knew any sexual passes he made would be rebuffed.[51] After several hours of talking, drinking and listening to music, Hicks "wanted to leave and [I] didn't want him to." In response, Dahmer bludgeoned Hicks with a 10 lb. dumbbell. He later stated he struck Hicks twice from behind with the dumbbell as Hicks sat upon a chair. When Hicks fell unconscious, Dahmer strangled him to death with the bar of the dumbbell, then stripped the clothes from Hicks' body before exploring his chest with his hands, then masturbating as he stood above the corpse. The following day, ,Dahmer dissected Hicks' body in his basement; he later buried the remains in a shallow grave in his backyard before, several weeks later, unearthing the remains and paring the flesh from the bones. He dissolved the flesh in acid before flushing the solution down the toilet; he crushed the bones with a sledgehammer and scattered them in the woodland behind the family home.
