Macroscopic characteristics of hacking trauma.

Area of Science:

• Forensic Science
• Bioarchaeology
• Anthropology

Background:

• Hacking trauma is common in forensic cases.
• Limited experimental research exists on differentiating weapon types based on bone trauma.
• Understanding weapon-specific bone injuries is crucial for forensic analysis.

Purpose of the Study:

• To experimentally investigate and characterize bone trauma inflicted by machetes, cleavers, and axes.
• To identify macroscopic features that distinguish wounds caused by these specific hacking tools.
• To provide a basis for recognizing weapon types in forensic contexts.

Main Methods:

• Multiple trials using machete, cleaver, and axe on pig (Sus scrofa) bones.
• Macroscopic examination of resulting bone wounds.
• Analysis of wound characteristics to differentiate between weapon types.

Main Results:

• Distinctive macroscopic characteristics were observed for wounds caused by each weapon type (machete, cleaver, axe).
• Specific features on the bone surface allow for differentiation of the hacking tool used.
• Experimental data provides a reference for forensic casework.

Conclusions:

• Machetes, cleavers, and axes produce recognizable and differentiable patterns of hacking trauma on bone.
• This research contributes valuable experimental data for forensic identification of hacking weapon types.
• The findings enhance the ability to interpret bone injuries in forensic investigations.
