In an investigation, what is typically the first item of ballistic evidence an investigator should look for?

• A. Unfired cartridges
• B. Ejected cartridges
• C. Victim testimony
• D. Location of the firearm

Answer: (B)

In a ballistic investigation, the first item of evidence that is typically prioritized is ejected cartridges. When a firearm is discharged, it ejects spent cartridges, which can provide critical information about the weapon used and the circumstances surrounding the shooting. Ejected cartridges often contain identifying marks from the firearm, such as firing pin impressions and extractor marks. These details are unique to specific guns and can help link a gun to the scene of the crime or confirm the use of a particular firearm. Furthermore, examining the location of the ejected cartridges can offer insights into the shooter's position and the trajectory of the bullets, which can be important in reconstructing the events of the incident. In contrast, unfired cartridges, victim testimony, and the location of the firearm may not provide the same immediate and tangible evidence regarding the specific circumstances of the shooting incident or the weapon used. Collectively, these factors highlight the significance of ejected cartridges as a crucial starting point in ballistic investigations.
