Crime scene investigation is a challenging and a convoluted process. Every crime scene is different and requires tremendous amounts of skill and brain to figure the intricate situation out. Mostly based upon innate skills, there are a massive amount of individual tactics and procedures that all come together to develop the process towards a successful crime scene investigation. Every crimes scene investigator has a provisional checklist in his mind. Even though every crime scene has its distinguishing features, there are a few general steps that can help in setting off the investigation and help develop the process customized to fit the scene. Here are a few top tips that can help in conducting a successful investigation.
Set and secure the perimeter
When you locate the focal point of the crime scene mark the area and seal the perimeter. Every minute that is wasted will enable errors. This allows you to preserve the crime scene so that you can be as near to accuracy as possible. Stopping time within this perimeter allows the investigation team to assess each and every detail of the crime scene. Moreover, if the scenery is grotesque or dangerous because it contains weapons then sealing the area will save more people from harm. Cordon off the scene and establish a single point for entry and exit. Make sure that the coming and going of all individuals is documented to avoid any mishaps.
Dealing with suspects
If you encounter or capture any suspects, they become a part of your crime scene investigation. First and foremost do not forget that you are still collecting evidence and any dealing with the suspect without a criminal lawyers adelaide can lead the investigation to complications. Law does not let go of human rights in any aspect. Any interrogations should be held in the presence of a criminal lawyer.
A crime scene investigator should absorb the scene as much as possible. When you secure the perimeter you are conducting a general survey. By now you have acquainted yourself with the event and the scene. Right after this you must start a detailed survey collecting hints and clues, pictures and props, and then note them down to work on the theories. Communicate and exchange notes within the team to walk yourself through the possible answers to what might have happened. This synchronization enables you to know the crime scene inside out.
Accuracy requires dedication. Before leaving the crime scene conduct a final survey to make sure that no stone remains unturned. Walking through the scene once again can help you brainstorm. As evidence keeps accumulating, theories can keep developing. Towards the end taking the final survey helps to put all theories and the scene into perspective. Preserve and record all evidence in an inventory log to keep a tab on it. All details of the crime scene should be covered in documentation and during the final survey everything should be tallied and cross checked.
