Surely we all have a notion of what this post refers to ... but every day you learn something new today I tell you a little more about this enigmatic and complex science that covers recreate from scratch any violent event or the last moments of a person's life and the possible cause that put an end to it.
Those who read my first post know that for several years I worked in a criminal investigation institution assigned to the area of forensic pathology so today I speak to you in the literature but also from my personal experience.
the forensic sciences are oriented and closely linked to criminal investigation ... any violent act that causes physical or psychological damage, whether partial or total, is understood (injury or death) to an individual. In fact, the criminal investigation is what drives forensic science in the search for the truth in order to exercise the application of sanctions and disciplinary measures to the perpetrator of the punishable act reprehensible by society.
All this research and reconstruction of facts covers a series of procedures and complex steps in which experts in different areas within the same branch are present and record the findings found to clarify some ambiguities or unsupported hypothesis ...
I present the main disciplines that encompass forensic science.
Not all of them are necessary to solve all the cases, in fact many of them apply only to specific cases.
Some examples.
Forensic Anthropology: this is a science that focuses its studies on bone material (cadavers or skeletons in skeletonization and reduction phase) is important when finding bodies that no longer have soft tissue because the anthropologist Through the study of bones can determine certain characteristics such as (sex, age, death data and in some cases to the context and race of the individual) being of vital importance when it comes to matching the characteristics of the bone found with lists of missing persons.
Toxicology: this discipline studies all types of substances and fluids foreign to the human body that can cause any alteration or damage to it. When an investigation of death by investigation is opened and the corpse does not present external lesions samples of gastric content, intracardiac blood and encephalon are sent to determine any substance that may have caused the death of the individual administered by (injection, inhalation or oral). This science is also applied to the accused or suspect. Blood and urine samples are usually taken to determine if he acted under the influence of a psychotropic or narcotic substance, which will have a great impact when making a judgment since it can increase or decrease the sentence. .
Psychiatric Psychology this science is generally applied to people who commit punishable acts to measure their intellectual capacity and their discernment, for example there are very neat and elaborate crimes that require a lot of organization and premeditation and when the person is interviewed can conclude that, although he could be the material author of the fact, could not have devised the whole plan so the intellectual author resides in another person and the research takes a different course. another example is where a person who committed a crime is evaluated to determine his mental stability and so by the result that throws the expertise, a judge can decide whether to send the accused to a mental rehabilitation institution or an ordinary penitentiary, low medium or maximum security to serve his sentence.
Biological Genetics and Forensic Odontology are used in very specific cases, usually in the matter of missing persons or when bodies are left in a state unrecognizable to the naked eye ... also when massive catastrophes occur. for example, a bus burns down and inside it there are 6 charred bodies. a dental record is made of each cadaver and relatives are questioned to determine if the characteristics of these records coincide with their family member. For its part, genetics can extract bone marrow content. This is obtained by scraping the inside of the larger bones such as the humerus or the femur ... ultimately it goes straight to the column ... through this test you get a DNA record that can be compared to a line relative collateral of the deceased (understand a brother) and obtain a result of 99% accuracy in compatibility. Genetics also covers fingerprint printing (necrodactyly), which is used to verify the identity of a corpse in a police record or before the entity that issues the identity card of each country.
Ballistics: exclusive for cases where firearms are involved. This discipline is very broad and studies the types of projectiles as well as the distance at which they were fired and the trajectory that the projectile follows in order to simplify and reduce the search field of the homicidal weapon and reconstruct a scene where the exact site can be identified from where they fired. When a good ballistic job and interrogation is done, the weapon and the suspect can usually be found within 48 hours.
Do you realize that it is not so simple? ... every day new techniques arise and the mind of some criminals is so twisted that you always have to go one step further to be able to get it right and it depends above all on a meticulous work of each one of the sciences involved in order to obtain a firm and unambiguous recostruccion of facts.
Remember that in a court all are innocent until proved otherwise by that where they do not make detailed and quality expertise with extensive descriptions judges dismiss cases and there is another free criminal in society because they can not convict someone that "maybe if "or" maybe not "is guilty

again the killer to the street.
This is just the introduction of a very broad topic and interesting friends I hope you liked and it serves to enrich your knowledge about something that is experienced daily and that we never perceive with the technical approach and all the things that it implies. but they already have a vision from the perspective of the researchers, if I see that they have liked to write soon a second more in depth post or on each one of the subdisciplines separately.

do not risk that I use my knowledge with you hahaha !!!
JUST KIDDING!!!
Happy day and blessings for all readers
