Final answer:
To help convict the suspect using lip print evidence, two qualitative pieces of evidence could be the uniqueness of the lip print pattern and the presence of any distinct features or marks on the lip print. One quantitative piece of evidence could be the comparison of the suspect's lip print pattern to a reference database of lip prints.
Step-by-step explanation:
To help convict the suspect using lip print evidence, two qualitative pieces of evidence could be the uniqueness of the lip print pattern and the presence of any distinct features or marks on the lip print. These qualitative pieces of evidence would focus on visual characteristics.
As for one quantitative piece of evidence, it could be the comparison of the suspect's lip print pattern to a reference database of lip prints. This would involve measuring and analyzing specific dimensions and features of the lip print, such as the width of the vermillion border or the length of the lip print.
