Forensic science involves use of forensic techniques (forensic laboratory or forensic psychology) to investigate what might have caused mysterious death in case of unknown death or disappearance of a person. The forensic science research proposes who would be involved, where and how the act of crime might have been committed.
Technologically DNA material is used to produce authenticity evidence about the lost person (John 2008). This initiates the go ahead in the investigation. Forensic laboratory employs use of foreign bodies or insects that are found on the site of a crime in case of a murder. The organisms are analyzed to come up with any concrete evidence of where the act might have occurred, whether the body was dumped somewhere else after the act. In forensic psychology, the suspect (s) or cross friends of the lost students are investigated to give the prior information on the condition of the student before disappearance.
