A forensic examination is a procedure performed by health professionals on the entire body in search of injuries and samples that might be used to aid a police investigation or a subsequent prosecution (Kobilinsky, 2011) . The examination can only be performed by a professional with the required qualifications and the right facilities. The historical data of the victim is analyzed and documented before a forensic examination is performed on them. Forensic scientists should approach a paint investigation with the comparison strategy in mind (Kobilinsky, 2011) . The comparison attempts should indicate whether the samples are different because the known and questioned paints should share a common origin. Paint has various ways of occurring as trace evidence depending on the mechanism of contact and the nature of the area of contact. Paints transferred from painted surfaces may come into contact as a smear or in chips. Depending on the forensic case under investigation, the paint may be identified in various objects. In a motor accident, for example, paint chips are formed and exchanged between the two surfaces of impact.
Paint examiners perform two types of analyses; the first one is the comparison of the known paint sample to an unknown paint sample. In this process, evidence container is opened and described then the examiner conducts a preliminary microscopic examination of the paint in the evidence. The paint is screened for any current details it has with the known paint (Muehlethaler Gueissaz & Massonnet, 2013) . A trace of little similarity is further analyzed in the trace unit. The other process is identifying the model of the paint; this analysis relies on similarities with the original equipment manufacturer paint structure. It focuses on both the upper coat and the undercoat. After the first findings, further investigation is done using other sources linked to the matter being investigated. Factors such as the paint's solubility, foreign objects on the color, the intensity of the impact, the time of impact and the victim’s orientation can be discovered during the forensic paint examination.
