The Crime Scene Investigation





Crime scene investigation

The crime scene is a physical location where a crime has happened and is very much necessary for an inquiry to be carried out and evaluated.  The investigation at the crime scene is very much necessary to identify what had happened at the crime and perhaps to identify the responsible persons who had committed the crime to enable execution of justice. Moreover, there are various means or ways of doing the investigation which includes; it can be done by carefully documenting the conditions at the scene to enable the presentation of the evidence at the criminal court for judgment. The documentation involves protecting the two parties since all of them are still suspects, gathering relevant information by carefully interviewing the subjects or the suspects (Sennewald, 2013).

 Additionally, the investigator will ensure that he or she has collected and recognized all the necessary or relevant physical evidence (Sennewald, 2013). This is important because not all evidence will be accepted at the criminal court by the persecutor and thus to avoid mistakes the investigator must collect the necessary information and perhaps the physical proof that can be seen and verified to be genuine and necessary for hearing. Most of the cases have bounced, and the criminal left due to lack of physical evidence collected at the crime scene and thus the misappropriate justice. Meanwhile, the investigator should use the machines like cameras, videos, and other recordings for the collection of evidence that is tangible and can be evaluated and therefore, the investigator should always ask for help since one person cannot perform all the tasks alone.

Categories of Evidence

The evidence available at the crime scene is not always the same and varies with weight, and hence there are some which are of interest to the investigator or the police (Sennewald, 2013). Most of the crimes reported in the new paper are usually of situations like a person has killed and thrown the body into the rivers and many glasses of water perhaps with the mind of destroying the evidence. Some of the suspects after performing such acts will disappear into thin air beyond reach and recognition. However, the forensic teams have managed to gather some particular evidence to trace what happened and get the suspects. The first evidence always heard of is the DNA samples collected to identify the person who was killed. The evidence will assist get to the family of the individual and begin the investigation for questioning and to find out what happened.

Moreover, some analysis is done on the found body ‘’ in the case of killings’’ to identify what killed the person and finally who did the act. Most of the analyses are done in the laboratory to gather the evidence and find out about the suspects. For example, the killing of a lady that took place in Chicago and the body dumped. The DNA samples were found, and this directed the investigators to the home of the person where further evidence would be obtained to determine the murderer. Fortunately, the whole house was clean, but the forensic personnel like Dr. Henry managed to use some chemicals which they sprayed on the floor and they were able to get some information like the person was murdered in the house and then dragged and dumped in the garbage (Sennewald, 2013).
