Trace evidence on spent bullets aids trajectory reconstruction. Combining this forensic evidence with geometric methods enhances event reconstruction in criminal investigations.

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.
