Summary

Fatal suicidal hyperinsulinemia, though rare, can be detected through postmortem insulin testing. This case highlights the importance of forensic analysis in unexplained deaths, especially when circumstances are unclear.

Area of Science:

  • Forensic Toxicology
  • Endocrinology

Background:

  • Self-induced hyperinsulinemia is infrequently reported, suggesting many cases may go undetected.
  • Insulin's role in metabolic regulation and its potential for misuse in fatal scenarios warrant forensic investigation.

Observation:

  • A case of fatal suicidal hyperinsulinemia in a non-diabetic individual is presented.
  • Retrospective biochemical analysis of a postmortem blood sample, stored for three weeks, revealed a positive insulin yield via radioimmunoassay (RIA).

Findings:

  • The positive insulin yield confirmed hyperinsulinemia as the cause of death.
  • This case underscores the necessity of a low threshold for suspicion in forensic investigations.

Implications:

  • Forensic analysis, including body fluid testing and tissue examination, is crucial when autopsy details are incomplete.
