Among the types of evidence collected from the crime scene, the trace is one of the necessary evidences that need to take into consideration during crime scene investigation. A well known accepted principle in criminalistics “Every contact leaves a trace” known as Locard’s exchange principle and is the basis for all forensic science as we know it today. The researchers employed the Qualitative-descriptive design of research using the phenomenological research with the methods of extracting trace evidences. Five(5) factors were identified and analyzed in the study; (1)Collection and preservation of blood, (2)Collection and preservation of saliva or semen, (3)Collection and preservation of urine, (4)Collection and Preservation of Body Fluids, (5)Collection and Preservation of Fingerprints. After the evaluation and analysis conducted, it concluded that the method for analyzing Trace Evidence in Criminal Investigations still used the conventional method of extracting trace evidence and still admitted as valuable evidence in prosecuting the person of interest(POI). It was strongly recommended to provide new technology in Forensic Science to be priority in all Crime Laboratories so as to minimize delays in the process of trace evidences.
