As fine evidence, animal hair can be used to identify contact between suspects and victims or to increase the value of evidence of other evidence by using features that easily transferred as material exchange takes place through contact between suspects and victims.

This study was conducted to find a quick and non-destructive analysis method of animal hair, which is the evidence of the incident, and aims to establish a DB for estimation of the source if animal hair is found at the scene. To this end, five gel samples of the cast method were compared and analyzed centering on the central part of the animal hair because it could show differences according to the growth of animal hair, and the results of classifying the cuticle into 10 types (WR, WIN, WIC, MP, MD, MB, SS, SA, ST) are as follows.

The analysis results are as follows:
1. Among the cast methods for animal hair cuticle analysis, C-CA, C-NC, C-PVA, C-PRG, and C-PRL methods were compared for gel samples, mold manufacturing time, and damage to samples using C-NC methods did not occur, and the mold production time was short.

2. The results of the analysis by the selected C-NC method are as follows. There was a difference in the type of cuticle that appeared according to the animal family, species, and variety, and it was confirmed that the WIC (37%) and WIN (28%) types of dog samples, and the WR (59%) types of cat samples were dominant. In addition, it was confirmed that there may be a cuticle type that predominates according to the variety, and that even though it is the same variety, there may be differences in the cuticle type that appears according to the individual. It was confirmed that several types of cuticle may appear in a single strand of hair, which is presumed to have been deformed the shape of the cuticle in the process of hair growth.

3. In wild animals and animal fibers, characteristics of the cuticle type appeared according to family, species, and individuals, and when comparing the cat family with the cat sample, it was confirmed that the type (WE, WIC) appeared in the cat sample and the dominant type (WR) of the cat family did not appear in the cat family. In addition, the MB type was identified as a type that appears only in the water deer and the SS type only in the Weaselidae, which is a cuticle type that appears only in a specific family or species and is distinct from other samples. The possibility of estimating the raw material was confirmed even in clothing made of fiber. However, since the animal fiber used in this study hardly went through the clothing manufacturing process, it was not possible to confirm whether the morphology of the cuticle was deformed or damaged by chemicals or dyeing drugs, so a related study is needed.

4. This study confirmed that when identifying or evaluating animal hair evidence at the scene of the incident, it was possible to first classification suspected hair samples by using the C-NC method, confirming the dominant types of dogs (WIC, WIN) and cats (WR), and types appearing only in specific family (weaselidae, SS) or species (water deer, MB). When conducting the identification or evaluation of animal hair evidence, various types of hair may appear depending on the growth of a strand of hair, so it must be made and analyzed centering on the center of the hair, and it can be used as data on cuticle through DB construction of animal hair according to breed.
