Spent shell casing found at a crime scene might be able to provide

Question

Quizplus · Accepted Answer

Spent shell casings found at a crime scene can provide valuable information to investigators. They can potentially indicate:
a. Where the assailant was standing: The location of shell casings can give an idea of the shooter's position, as casings are typically ejected from a firearm in a predictable pattern and direction. However, it should be noted that casings can be moved or affected by external factors such as the environment or secondary impacts.
b. Where the assailant was facing: The direction in which the casings are ejected can sometimes suggest the direction the shooter was facing, although this is less reliable than other indicators due to the many variables that can affect the trajectory of a casing after ejection.
c. Type of weapon used at the crime scene: The size, shape, and markings on a spent shell casing can help identify the caliber of the weapon and potentially the make and model of the firearm used. This is because different firearms leave unique markings on the casings they eject, which can be matched to specific types of weapons.
Given the information above, the correct answer is:
d. Choice 'a', 'b', & 'c' are correct.
Spent shell casings can indeed provide clues about the assailant's position, the direction they were facing, and the type of weapon used during the commission of a crime. However, the interpretation of this evidence should be done carefully and ideally by a forensic expert who can account for the various factors that might influence the final resting place and condition of the casings.
