Study Notes
Physical Evidence and Group Association
- Physical evidence that can be linked only to a group includes fibers, paint chips, and glass fragments.
- These types of evidence do not possess unique characteristics that can pinpoint a specific source.
Hair as Class Evidence
- Hair is classified as class evidence because it lacks nuclear DNA in its standard form, making it impossible to trace back to a single individual.
- When examined, hair can indicate characteristics such as color, length, and racial origin, which are common to a group.
Category of Evidence with Nuclear DNA
- Biological evidence refers to anything that contains nuclear DNA.
- This category includes items like blood, saliva, and tissue samples, which can provide definitive identification of an individual.
