Which individual would be most helpful for determining bullet trajectories at a homicide scene?

The firearms examiner is the individual most equipped to determine bullet trajectories at a homicide scene due to their specialized training and expertise in firearms-related forensic evidence. This role typically involves analyzing bullet characteristics, understanding ballistics, and applying knowledge about how projectiles travel through different environments.

When investigating a crime scene, understanding the trajectory of bullets is crucial for reconstructing the events that occurred. A firearms examiner can employ tools and techniques, such as utilizing trajectory rods or laser systems, to create a three-dimensional understanding of where bullets have traveled, which helps in assessing the positions of victims, shooters, and potential escape routes. Their foundational knowledge about how bullets behave in various conditions is essential for accurate analysis and assists law enforcement in piecing together critical aspects of the case.

In contrast, while the other professionals have valuable contributions—such as the medical examiner focusing on determining cause and manner of death, the forensic tech collecting and preserving evidence, and the crime scene investigator managing the crime scene and collecting evidence—the firearms examiner’s specific expertise in projectile dynamics positions them as the key figure in assessing bullet trajectories.
