A complex electrocution case: the role of SEM-EDS analysis in identifying the entry and exit point of the electric...

Electrocution, although uncommon in forensic practice, remains a significant cause of accidental death. We report a fatal case involving a 35-year-old singer who collapsed during a live performance. The autopsy revealed burn-like lesions on the hand holding the microphone, along with non-specific cutaneous lesions at multiple body sites. Scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS) analysis identified numerous metallic particles on a toe and fewer particles on the hand. The detection of bismuth on the toe was unexpected and suggested an atypical electrocution mechanism involving a defective electrical cable containing a non-standard solder. This hypothesis was subsequently supported by expert evaluation of the electrical system. This case highlights the crucial role of SEM-EDS in the investigation of complex electrocution deaths. It emphasizes the need for careful examination of all cutaneous lesions, including those with atypical appearances, to detect potential evidence of electrical injury. In addition, the findings illustrate that metallization may occur at both the entry and exit points of the electric current, warranting cautious interpretation of lesion distribution.
