The unique marks that can be left on a bullet or bullet casing when fired are Rifling patterns, Breech marks, Firing pin impressions, and Extractor/ ejector marks.
Explicación
## Step 1The question is asking about the unique marks that can be left on a bullet or bullet casing when fired. These marks are unique to each firearm and can be used to identify the specific weapon used in a crime.## Step 2Rifling patterns are the unique spiral grooves cut into the barrel of a firearm. When a bullet is fired, it passes through these grooves, leaving a unique pattern on the bullet. This pattern can be used to identify the specific firearm used.## Step 3Breech marks are unique marks left on the bullet or casing due to the interaction with the breech face of the firearm. The breech face is the part of the firearm where the bullet is loaded. When the bullet is fired, it is forced against the breech face, leaving a unique mark.## Step 4Firing pin impressions are unique marks left on the bullet or casing due to the interaction with the firing pin of the firearm. The firing pin is the part of the firearm that strikes the primer of the bullet, causing it to ignite. When the bullet is fired, the firing pin leaves a unique mark on the casing.## Step 5Extractor/ ejector marks are unique marks left on the bullet or casing due to the interaction with the extractor or ejector of the firearm. The extractor and ejector are parts of the firearm that remove the spent casing from the firearm after the bullet has been fired. When the casing is ejected, it is marked by the extractor or ejector.## Step 6Generio marks and erasure marks are not typically associated with firearms. They are more likely to be found on documents or other items, not on bullets or casings.
