Suicide Via Insulin Overdose in Nondiabetics

Abstract

Four cases of self-injected insulin overdose in nondiabetic individuals are presented. Included are two cases of presumed insulin overdose (no autopsy), one case with elevated vitreous insulin (autopsy), and one case with elevated postmortem blood insulin and low blood C peptide (autopsy). These cases demonstrate the need for a thorough scene investigation, complete autopsy, and proper collection and storage of specimens to certify a death caused by insulin intoxication as well as to determine the manner of death. Appropriate collection and preservation of postmortem blood samples are discussed.
