Analysis of unique atypical screwdriver injuries

Area of Science:

• Forensic Pathology
• Trauma Analysis

Background:

• Sharp and pointed instrument fatalities are uncommon in the US.
• Screwdriver tip shape influences wound patterns, aiding in weapon identification.

Observation:

• A case of an adult male fatality with multiple injuries was investigated.
• Autopsy revealed penetrating wound patterns consistent with a six-point star (Torx) screwdriver.

Findings:

• The Torx screwdriver, with its blunt head, produced hybrid injuries combining penetrating and blunt force characteristics.
• This represents the first reported fatality involving a Torx screwdriver as a weapon.

Implications:

• Forensic pathologists must recognize atypical penetrating wounds to identify rare weapons.
• Detailed injury documentation and comparison are crucial for identifying the weapon when it is not recovered.
