This study found that burning does not obscure cleaver marks on bone, even after fragmentation. These chop marks remain identifiable, aiding in forensic analysis of burned remains.

Area of Science:

  • Forensic Science
  • Bioarchaeology
  • Anthropology

Background:

  • Trauma analysis in skeletal remains is crucial for forensic investigations.
  • Understanding the effects of postmortem environmental factors, such as fire, on skeletal trauma is essential for accurate interpretation.

Purpose of the Study:

  • To evaluate the impact of burning on cleaver-inflicted trauma in bone.
  • To assess the diagnostic value of cleaver marks after exposure to fire.

Main Methods:

  • Thirty pig forelimbs and 30 beef ribs were subjected to cleaver and knife trauma.
  • Bones were then burned in an outdoor fire with deliberate agitation to simulate cremation and fragmentation.

Main Results:

  • Hacking trauma was observed to weaken bone structure.

  • Fire exposure increased the likelihood of fragmentation at trauma sites.
  • Cleaver (chop) marks remained identifiable on burned bone, with characteristics largely preserved.

    • Conclusions:

    • Burning does not eliminate the diagnostic potential of cleaver marks on bone.
    • Cleaver marks are resilient to cremation, aiding in the identification of hacking trauma in burned skeletal remains.
