How to identify a person using forensic science

Hello everyone,

My name is Joanna and I am a blogger from Poland invited to write a guest post for you. My own blog is https://csimiami.wordpress.com where I describe different topics related to CSI:Miami police procedural drama. The aim of my blog is to show people that the TV show that they like includes plenty of useful information alongside of entertainment and action they can notice at first.

Today I would like to discuss one of the biggest part of working as a crime scene investigator, which is identification of the people using forensic science methods. Below I want to introduce some of forensic science techniques most commonly used to identify the people who died or whose names are unknown for example because of the missing documents. I guess, you have seen them all in police procedural films, such as CSI:Miami but it is never too late to learn something new

How to identify a person using forensic science

Ear print analysis

Ear print analysis is used as a means of forensic identification intended as an identification tool similar to fingerprinting. An earprint is a two-dimensional reproduction of the parts of the outer ear that have touched a specific surface (most commonly the helix, antihelix, tragus and antitragus). The first ear print identification of a criminal was made in Switzerland in 1965 and ear print analysis has also been successfully used to solve crimes in the UK and the Netherlands. In addition to identification, the height of an ear imprint at a crime scene may also provide investigators with information regarding the stature of the perpetrator. The European Commission is currently trying to create a database that will set the worldwide standard for ear print analysis. Ear print analysis is considered to be more economical than DNA profiling, and is considered to be very reliable. Check about the Phasing Power in physics.

Forensic anthropology

Forensic anthropology is the application of the anatomical science of anthropology and its various subfields, including forensic archaeology and forensic taphonomy, in a legal setting. A forensic anthropologist can assist in the identification of decomposed or unrecognizable corpses. Forensic anthropologists are also instrumental to the investigation and documentation of mass graves. Together with forensic pathologists, dentists, and homicide detectives, they commonly testify as experts. Using physical markers present skeleton, a scientist can potentially determine age, sex, stature, and ancestry of the body. In addition to identifying physical characteristics of the corpse, they can use skeletal abnormalities to determine cause of death, past trauma, diseases or medical procedures.

Forensic dactyloscopy

Fingerprint identification the comparison of two instances of friction ridge skin impressions from fingers, toes, palm of the hand or sole of the foot. It is used to determine if they could have come from the same person. The flexibility of friction ridge skin means that no two prints are alike in every detail. Fingerprint identification involves an expert or a computer system, determining whether two prints are likely to have come from the same body part.

Quantum Entaglement is the best thing everyone should know.

Forensic DNA analysis

DNA profiling is used to identify individuals by characteristics of their DNA profile – small set of DNA variations likely to differ unrelated individuals. DNA profiling should not be confused with full genome sequencing. It is mostly used not only to determine identity, but also to confirm paternity or the the culprit’s presence at the crime scene.

Forensic odontology (aka forensic dentistry)

Forensic odontology is the application of dental knowledge to laws enforced by police agencies in justice system. Forensic dentists assist investigators to identify recovered human remains in addition to the identification of whole or fragmented bodies. They may also be asked to determine age, race, occupation, previous dental history and status of unidentified people.

Forensic pathology

Forensic pathology focuses on medical examination of the body to determine the cause of death. Autopsy id done by the medical examiner or coroner during the criminal or civil law cases investigation and is often used to identify the victim.

Forensic podiatry

Forensic Podiatry is a forensic science sub-discipline in which knowledge of forensic medicine is used together with knowledge about the human foot to examine foot-related evidence in criminal investigation context.

Wrap up

            There are numerous options, which the police can use to identify the people. The ones above are those mentioned most often and probably the most effective forensic science methods of identification.
