 The entire dismemberment process took Dahmer approximately two hours to complete, and he disposed of all of Tuomi's remains—excluding the severed head—in the trash.For a total of two weeks following Tuomi's murder, Dahmer retained the victim's head wrapped in a blanket.After two weeks, Dahmer boiled the head in a mixture of Soilex (an alkali-based industrial detergent) and bleach in an effort to retain the skull, which he then used as stimulus for masturbation.
