The role of the forensic entomologist is mainly to help determine the postmortem interval by examining which insect populations inhabit the body. A trained behavioral scientist can uncover some of these patterns and help predict when, how, and against whom the serial criminal will strike next. An interesting approach to diagnose the cause of infantile sudden death was the immunostaining of the components of human and cow milk in the lung. Brain tissue is sometimes saved for toxicology testing because many of the drugs act on the central nervous system. Although the legislation regarding forensic pathology differs between countries, a common principle is that in the investigation of a possible or suspected criminal death, a forensic pathologist is engaged through a formal request from the police or the prosecutor. For the discrimination of antemortem bleeding from postmortem hemoglobin diffusion, immunostaining of glycophorin-A and its quantitation are useful. Such predictions may enable the police to prevent the next crime in the series. This expert role continues throughout the process, including the court proceedings on request of the court and/or one of the parties. Forensic pathology has a treasure trove of research assets including population-based epidemiologic data, a window on unnatural deaths, and the only remaining significant source of autopsy tissues. Although the determination may be straightforward in a normal case, it can be problematic in a death of suspicious origin. A very important role of a behavioral forensic scientist is in interviewing and interrogating suspects and witnesses to crimes. Certain insects will attack the body right after death, whereas others will wait until some decay has taken place.

Consequently, to be a practicing forensic pathologist, one must also be a medical doctor. Therefore, even though the magnitude of decedents at an MFI can be overwhelming, forensic pathologists must still apply this credo. Kidney tissue should be saved for analysis of heavy metals. The field has evolved into a discipline of investigative techniques coupled with the science of postmortem dissection. The chief medical examiner will, in turn, have a number of associate medical examiners who perform the actual duties of the forensic pathologist. Some examples of other studies using quantitative immunoassays in forensic pathology are: vascular endothelial growth factor (VEGF) contents in brain and some other organs for the diagnosis of postmortem interval/time of death, melatonin concentrations in blood, urine, and pineal gland for the same purpose, and serum triptase concentration for the diagnosis of heroin-related death. It can be defined as “a branch of medicine that applies the principles and knowledge of the medical sciences to problems in the field of law,” (DiMaio & DiMaio, 2001, p. 1). It is advisable to obtain and freeze a portion of liver from the right lobe routinely and other tissues as indicated. In addition to this role of the behavioral forensic scientist, there are several other emerging duties. One is in the area of psychological crime scene reconstruction and psychological profiling. If blood is not available, muscle, brain, lung, and kidney are the most useful tissues for diagnosising death from carbon monoxide exposure and may also be used to determine deaths due to carbon monoxide inhalation before thermal injury.89 Lung tissue (50 g) stored in a nylon but not a plastic bag may aid in evaluation of volatile substance abuse or exposure.6. The forensic pathologist’s work is directed to assisting in predominantly judicial or legal processes by establishing manner, time, and cause of death.
