Forensic pathologists are specially-trained physicians who work with law enforcement to determine the cause of a suspicious death in a case. They perform an autopsy to examine the body; they test blood and tissue samples, check for indications of injuries caused by firearms or other weapons, and seek other trace evidence that may provide information to the case. Before they make determinations on the cause of death, forensic pathologists also study the victim’s medical history and evaluate other evidence collected at the crime scene and witness statements. Once they compile and analyze the evidence, they prepare a report and may need to testify the reasons behind their findings in court.
