Time of Death Estimation
At the University of Tennessee At Knoxville, a two-and-a-half-acre field is dedicated to the study of human remains. The Body Farm has made important contributions to estimating the time factors involved in suspicious deaths. The field has provided valuable information in the field of forensics. Forensic Science allows investigators to unmask the secrets of a crime scene. In criminal cases involving a victim, it is crucial that all evidence be gathered to help solve the crime. One of the most important factors is establishing the time in which the crime occurred. A medical examiner will examine the victim and estimate the time of death based on a variety of changes to the body following death. The medical examiner is the most important individual in an investigation involving a victim. The medical examiner is usually a physician specializing in forensic pathology, the study of structural and functional change in the body because of injury. The medical examiner can determine if the caus
While these are good indications of the time of death they are not the only factors taken into consideration by the medical examiner. Other personal factors may also include talking to a friend or relative of the victim. The application of this new technology allows investigators to have faster access to crucial information and to solve the crime faster. The medical examiner may trace the victim's last meal as a way to establish when the person expired. Rigor mortis can last up to thirty-six hours before the body begins to go limp again. Therefore, without the use of forensic science, it would be almost impossible to produce the best evidence to serve justice and protect the public. The faster the crime is solved ,the less chance for the criminal to strike again. More often than not, it would be impossible to solve a crime without forensic science. If someone was last seen or heard from at a certain time, then obviously that person was not dead. This refers to the cloudiness that occurs in the eyes following death. The medical examiner's job is tedious, time consuming, and he or she must always be on the alert for methods that have not yet been documented. The most common factor to determine the time of death is rigor mortis. Eyes that are closed will develop the same conditions, but the hazy film may take up to an entire day to settle in. The responsibility of the medical examiner to conduct an autopsy, examine medical evidence, study the victim's history, and put together all the information in a report to be turned in to the proper authorities. The medical examiner uses many different means to establish a time of death.
