Death or injury caused by electrocution.

R K Wright

    Clinics in Laboratory Medicine
    |June 1, 1983
    PubMed
    Summary

    Investigating electrocution deaths requires suspicion, as physical evidence is often minimal. Autopsy findings vary significantly based on voltage and current type, complicating diagnosis.

    Area of Science:

    • Forensic Pathology
    • Electrical Engineering
    • Toxicology

    Background:

    • Electrocution investigations often face challenges due to the lack of definitive physical evidence on victims.
    • Understanding the electrical parameters (voltage, current type) is crucial for accurate forensic analysis.
    • Autopsy findings in electrocution cases can be subtle and non-specific, necessitating a thorough approach.

    Purpose of the Study:

    • To highlight the importance of a high index of suspicion in electrocution investigations.
    • To detail the diagnostic approach for electrocution, differentiating between low and high voltage incidents.
    • To describe the typical autopsy findings associated with different types of electrical injury.

    Main Methods:

    • Case review emphasizing the need for scene photography and documentation.
    • Electrical examination of implicated equipment in low voltage cases.
    • Detailed autopsy examination focusing on burns and asphyxia indicators.

    Main Results:

    • High voltage electrocution typically presents with burns and asphyxia findings.
    • Low voltage alternating current electrocution may lack external burns and specific cardiac signs.
    • Low voltage direct current electrocution infrequently results in fatalities.

    Conclusions:

    • Electrocution investigation demands meticulous scene assessment and suspicion due to often absent victim findings.
    • Autopsy findings are variable and depend heavily on the electrical source characteristics.
    • A comprehensive approach integrating scene investigation, equipment analysis, and autopsy is essential for accurate electrocution death determination.
