Area of Science:

  • Forensic Pathology
  • Legal Medicine
  • Suicidology

Background:

  • Sharp force injuries are a significant cause of suicide.
  • Understanding epidemiological and social factors is crucial for suicide prevention strategies.

Purpose of the Study:

  • To analyze wound patterns in sharp force suicides.
  • To investigate related epidemiological and social factors.

Main Results:

  • The study identified 16 cases (10 male, 6 female) aged 19-79.
  • Kitchen knives were the most common weapon (n=8); fatal incised wounds (n=13) and neck injuries (n=6) predominated.
  • Eight cases showed tentative wounds, and six had hesitation marks, suggesting prior suicidal ideation or attempts.

Conclusions:
