Research Proposal On Types Of Evidence
A well developed and collected latent fingerprint
This is an individual evidence because it can be uniquely identifiable to a specific person. There are no two people with the same fingerprints and they do not change over time
Random striations on a discharged bullet
This is an individual evidence because it can be specifically identifiable to a source. Striations have unique patterns that are produced when it passes the barrel of a firearm. Investigators will look into these unique patterns to determine the source.
3. A single-layer paint chip
This is a class evidence. All paint chips have common characteristics; thus, cannot be traced to a unique source.4. A footwear impression with irregular and random wear patterns
This is an individual evidence because the irregular and random wear patterns can be traced to a unique source. Footwear impressions can tell the sequence or manner of walking of the wearer.5. A bloodstain with no DNR-containing cells
This evidence is a class evidence because there are no DNR-containing cells; thus, it cannot be uniquely identifiable with a source.6. An artificial fiber
This evidence is a class evidence because the characteristics of the artificial fiber is common to a group. There are several artificial fibers with the same characteristics. No matter how thoroughly the fiber is examined, no individual identification can be made.7. Irregular edges of a broken knife fitted together
This is an individual evidence because the irregular edges match like a puzzle which makes it unique to the broken knife.
