Forensic biology has been used to prove how a crime has been done and by whom it has been committed.
Left behind materials, weapons and traces that establish the identification of the criminal and the victim will be examined thoroughly to ratify a report. Evidences left in the crime scene will be tested using molecular biology or DNA Testing.
Blood stains, cigarette butts, tools or weapons and any other materials left that can be used as evidence will be examined through DNA testing. The victims as well as the suspect will also undergo DNA analysis to cross-match with the evidences found. With this, truth can be revealed and justice will be served.
