Forensic scientists play a crucial role in the criminal justice system by collecting, analyzing, and interpreting evidence to help solve crimes and determine the truth.

Dactylography is the scientific study of fingerprints, including their identification, comparison, and classification. It is used to identify individuals and link them to crime scenes.

Rigor mortis is the stiffening of the body after death, which typically begins within a few hours and lasts for several days. It can provide valuable information about the time of death.

Bloodstain pattern analysis is a specialized field of forensic science that involves the study of bloodstain patterns at crime scenes to determine the sequence of events and the actions of individuals involved.

Dental records, such as X-rays and charts, can be used to identify a person's age by examining the development and condition of their teeth.

Ballistics is the study of firearms and ammunition, including the analysis of gunshot residue, which can provide information about the type of firearm used and the distance from which it was fired.

Odontology is the study of teeth and their structures, including the analysis of bite marks. It is used to identify individuals and link them to crime scenes through the comparison of bite marks on victims or objects.

Autopsy reports provide detailed information about the cause of death, including the nature and extent of injuries, as well as any underlying medical conditions that may have contributed to the death.

Trace evidence analysis involves the examination and comparison of small pieces of evidence, such as fibers, hairs, and other microscopic particles, to link individuals or objects to a crime scene.

Graphology is the study of handwriting, including the analysis of handwriting samples to determine the writer's identity or characteristics.

Soil analysis involves the examination and comparison of soil samples to determine their composition and characteristics, which can be used to link individuals or objects to a crime scene.

Toxicology reports provide information about the presence and concentration of drugs or alcohol in a person's system, which can be used to determine intoxication or impairment.

Tool mark analysis involves the examination and comparison of tool marks, such as those left on a crime scene or on evidence, to determine the type of tool used and potentially link it to a specific individual.

Tire track analysis involves the examination and comparison of tire tracks, such as those left at a crime scene or on evidence, to determine the type of vehicle that made them and potentially link it to a specific vehicle.

Digital forensics involves the examination and analysis of digital evidence, such as computer files, electronic devices, and network traffic, to extract and interpret information relevant to a criminal investigation.
