Complicated suicide versus autoeroticism?: a case involving multiple drugs and a porta-potty.

In this report, a unique and bizarre case of complicated suicide is presented. The decedent was found dead in the basin of a porta-potty, wearing women's pantyhose, jewelry, and makeup. The initial investigation was suspect for homicide. Although an autoerotic accidental death cannot be excluded, the patient's medical history and autopsy results provided evidence for suicide, including several substances positive in his serum. Tramadol was quantified to be 140 mg/L, approximately 470 times the therapeutic range. Moreover, formaldehyde was also present, presumably absorbed from the contents of the chemical toilet. An exhaustive search could not reveal similar circumstances of suicide in a porta-potty or with the levels of tramadol found in the decedent.
