Trajectory reconstructions. I: Trace evidence in flight

Area of Science:

• Forensic Science
• Ballistics Analysis
• Trace Evidence Examination

Background:

• Establishing projectile trajectories is crucial in forensic investigations.
• Spent bullets often retain trace evidence from their environment.
• Traditional trajectory analysis relies on geometric principles.

Observation:

• This review examines the utility of trace evidence found on spent bullets.
• The study integrates trace evidence analysis with geometrical trajectory reconstruction.
• Five case studies demonstrate the application of these methods.

Findings:

• Trace evidence analysis on bullets provides valuable data for trajectory reconstruction.
• Combining trace evidence with geometric data improves the accuracy of event reconstruction.
• The reviewed cases highlight the practical application of this integrated approach.

Implications:

• This methodology enhances the investigative capabilities in forensic ballistics.
• It offers a more comprehensive understanding of shooting incidents.
• The findings support the use of advanced trace evidence analysis in legal proceedings.
