How to Investigate a murder case:
In crime investigation, there is a branch of it which deals with murder investigation, and if detectives and police want to be succesful at it, they have to follow certain steps. Stricktly speaking, they have to go to the crime scene to check what has just happened and make notice of every single detail. For instance, they must be aware not to miss any declaration at the moment, that is to say, to interrogte every witness or suspect that appear at the moment or afterwards. What’s more, they should be aware of everyone’s declarations, for any of them could suddenly turn into a suspect. With this, investigators should be successful in the investigation.
To begin with the investigation, the first step is to gather all the evidence that is possible. For instance, they can get blood samples (if there is blood), that can be taken from the floor, clothes, walls and even the most unthinkable places. Apart from this, looking for hair from the murderer and fingerprints is very important. Besides, the victim’s body autopsy can reveal a lot of things about his death, for example, the way he was killed and whether he tried to defend himself from the attack or showed resistance. Furthermore, they also have to analyse the evidences after gathering them. In the case of fingerprints being found and revealing the person’s identity or maybe hair is found and through a DNA test they can guess who this person is. Another thing is that, if there was a homicide weapon, like a revolver or a knife, it is very important to find it, not only because it contains more evidence, but also because it can be of greater help for the trial, although sometimes the only weapon could have been a plastic bag, a rope o just the murderer’s hands. When all evidence is gathered there is nothing left but to move on to the other step.
Afterwards, the possible suspect should be immediately arrested and interrogated. However, if then investigators corroborate that they had some kind of relationship, as for example, a love or family relationship between themselves or not. For that matter, if there was a reletionship, what they must do is to find try the reason why this person killed the other, for this reason could be, like in some cases due to child molesting, family violence or jelosy, in the case of a couple or parents being killed. After doing this, they should interrogate the witnesses again, through this, they can built up the history of the murdered person and tell them how the relationship between them really was.
When there is enough proof against one suspect, trial is what should be done next. In murder trials, what lawyers usually do is to expose all the evidence, giving correct explanations about the place they were found in and describing again the crime scene, maybe by making a reconstruction of it. And then it comes when forensic doctors tell all about the victim’s autopsy, how it was found and most importantly, the cause of the death. Aside from that, to interrogate the murderer and the possible witnesses to the case is a key point in the trial process, because by these testimonies, lawyers and judges will be able to analyse the facts more easily to come to a conclusion . With that, the judge or maybe the jury, must come to a conclusion and decide whether the accused is guilty or innocent, and if he is guilty, they must sentence him fairly.
In effect, crime investigation consists of following steps and being very careful about all the things that are found in the scene. In short, the most important things are: body position according to the death, all the evidence that is found, such as fingerprints and blood samples. It is also all about interrogating the witnesses and any possible suspect at the moment.There is also the trial itself, which is a great and painful process for the family of the victim. To sum up, investigators should get to have certainty about what happened and if they are successful, get to have the murderer behind the bars for a very long time.
