CSI Investigation

• Has the murder taken place in this room

• Has the body been replaced

• Has any object been moved (especially by first responders or family members)

• Were there presence of additional shots (if it’s a shooting that has taken place), other than on the victim’s body, around the place

• Are there traces of blood in other areas of the place

• Is blood drops/spatter present elsewhere apart from the victim’s body

• Are there signs of a struggle

• Are there any kind of footprints visible anywhere especially in the blood stained areas

The above questions are just some prominent ones a CSI may encounter with. As one

The photos must have the overall, medium range and close-up shots of any potential physical evidence. When considering the close-up shots, the scales can be included as to refer later. Composing the Crime Scene Sketch

Preparation of the crime scene sketch is the next job of a CSI. Most CSIs will prepare the rough sketch at the spot and completes a full detailed sketch back at their workplace. While preparing the rough sketch, the CSI must take utter care to see that the rough sketch must not contain anything more or less than the final report. The assistant in the crime scene investigation has the role to assist the CSI with the measurements and finally the report may be revised by the same for any corrections if he thinks is required in the document.

Each nook and corner of the location must be revisited by the CSI in order to get even the smallest piece of evidence, if any. Many crime scenes use an evidence vacuum in the scene for collecting any micro particle as evidence such as hair and fibers which may become a useful link to the culprit. This is the step that must be performed prior to any close inspection of the

The pertinent evidence must be kept uncontaminated until it can be recorded and collected. A prosecution to be successful, the evidences must be in a condition that can be relied upon as an evidence. A crime scene must be protected by the police officers by sealing the entire location from public entry. This protection ends when the scene is released from the police custody.

The police and associated officers are trained properly based on the protection of evidences and crime scenes. Because of this, any police officer can be put into the position of first responding officer to a crime scene. This first officer should approach the scene in a slow pace and methodically. But sometimes this may act impractical. The officer may be busy in any other works of the case such as rescuing the victim. But the officer should make mental or written notes about the condition of the scene. The officer must keep notes on the times involved in attending to the crime scene like time dispatched for crime scene, time left etc. The disturbance caused to any objects, items or place must be taken care of with great effort.
