The discipline of forensic epidemiology (FE) is a hybrid of principles and practices common to both forensic medicine and epidemiology.FE is directed at filling the gap between clinical judgment and epidemiologic data for determinations of causality in civil lawsuits and criminal prosecution and defense.
Both the person accused of the crime and the accuser would give speeches based on their sides of the story. The case would be decided in favor of the individual with the best argument and delivery. This origin is the source of the two modern usages of the word forensic—as a form of legal evidence; and as a category of public presentation. [6]
Arguably, a crime scene reconstructionist is a forensic scientist who specializes in interpreting and assembling evidence in a coherent manner. Chisum and Turvey explain that to perform crime reconstruction one need not "be an expert in all forensic disciplines" but "must become an expert in only one: the interpretation of the evidence in context."
Bloodstain pattern analysis (BPA) is a forensic discipline focused on analyzing bloodstains left at known, or suspected crime scenes through visual pattern recognition and physics-based assessments. This is done with the purpose of drawing inferences about the nature, timing and other details of the crime. [ 1 ]
Shoes have many different prints based on the sole design and the wear that it has received – this can help to identify suspects. [15] Skid mark – mark a tire makes when a vehicle wheel stops rolling and slides or spins on the surface of the road. Skid marks are important for finding the maximum and minimum vehicle speed prior to the impact ...
Many forensic pathologists practice as a histo (hospital) pathologists before moving onto forensic science. Another requirement for forensic pathologists includes having a working knowledge of specific fields of study like toxicology, firearms examination (wound ballistics), trace evidence, forensic serology and DNA technology.

These same workers also tend to be opposed to overhauling the system. As the study pointed out, they remain loyal to “intervention techniques that employ confrontation and coercion — techniques that contradict evidence-based practice.” Those with “a strong 12-step orientation” tended to hold research-supported approaches in low regard.
From country to country, different STR-based DNA-profiling systems are in use. In North America, systems that amplify the CODIS 20 [21] core loci are almost universal, whereas in the United Kingdom the DNA-17 loci system is in use, and Australia uses 18 core markers. [22] The true power of STR analysis is in its statistical power of discrimination.
