The essay it's about crime and criminology . In the essay you can find useful information of how crime it i...
Criminology can be described as a science that uses research tools to obtain evidence that
will be analysed in a laboratory.
The tests are used for criminal acts and are bases on scientific principles to identify the
cause of the crime.
The main key to finding out the type of agent or instrument used in the facts, this
established that after an assassination there is always a trace of the means used that caused
the death, since if force had been use through a procedure such as (straggling, weapons,
rape, etc) as well as chemical components as (poisonings, intoxications) they can also be
physical (burns, electricals) or biological such as bacteria or viruses.
Faced with a crime, the murderer always leaves a trail of material evidence of his
participation at the scene.
The most common trace is usually DNA remains or fingerprints.
At the crime scene there is always an exchange of materials such as synthetic, biological,
and genetic, between the victim and the murderer, for example:
In a case of rape there is an exchange of fluids, scratches, blood, tissue remains that
facilitate reconstruction of the facts and identification of the murder.
Once all the tests and evidence have been compiled in accordance with the previous four
principles, the reconstruction will begin the facts step by step and in the order and way
each of the events occurred.
When a crime happens, forensic investigators along police officers find and investigate the
crime scene.
Why and when a crime scene is investigated:
When a crime happens, be as robbery, violent crime, rape, shooting , stabbing etc , the
police force is the first sector that attend to the scene , then the forensics are called to
investigate and find the required evidences , they collect and send the evidences founded to
a scientific laboratory to find the accusing .
During the investigations carried out at the time found, the forensics /detectives together
with the police collect information and develop their conclusions of how and why the
victim was found dead and why they killed her, that’s why it is very import as to why and
when investigating a crime scene, detectives must be very captative, careful, reasonable
