In the early morning hours of May 27, 1991, 14-year-old Konerak Sinthasomphone (the younger brother of the boy Dahmer had molested) was discovered on the street, wandering nude. Reports of the boy's injuries varied. Dahmer told police that they had an argument while drinking, and that Sinthasomphone was his 19-year-old lover. Against the teenager's protests, police turned him over to Dahmer. They later reported smelling a strange scent, which was later found to be bodies in the back of his room. Later that night, Dahmer killed and dismembered Sinthasomphone, keeping his skull as a souvenir.
