The first step to solving a crime is getting all of the information at its source.  This means going down to the crime scene and collecting all the evidence. There are plenty of things that can be learned from a crime scene if you know how and where to look.

Following the proper procedure in analyzing a crime scene is important to the case. An organized method yields the most information possible, something essential in any case.

Seal Off

Sealing off the crime scene is the first order of business. This is to prevent the area from being disturbed. It is essential that everything is left exactly the way it was found so that investigators are only dealing with evidence relevant to the case. Investigators also need to keep witnesses nearby to learn what they can from them. Keep the witnesses separate to maintain an objective account of events. The suspect may still be on the premises, which is important to keep in mind.

Seal the area off with barrier tape, vehicles, and anything else that will protect the evidence. If it is raining, protect thing such as bodies or footprints using umbrellas and tarps (Citation 2).

Interview

It isn't uncommon to find the suspect lingering near the crime scene. It is also important to receive first-hand accounts of the events that took place from witnesses. The best way to get this information is through interviewing them. Questions asked must be relevant to the case.

Documentation

 Documentation is to record the condition of the crime scene and where everything has been found. It's needed to be able to reconstruct the scene later on. The more accurate, the better.

  • Video - A video walkthrough contributes a 3-D view of the overall scene.
  • Photography - Photographs should be for more detailed things such as footprints or blood spatter on the walls.
  • Sketch - A sketch of the scene is for things photographs can't convey well. Photographs are converting three-dimensional objects into two-dimensionals, and a sketch can make up for that.
  • Notes - Take written notes of things noticed at the crime scene that can't be expressed in video or photography (Citation 1).

Collect Samples

There are plenty of things found at crime scenes that can be taken in to the lab for further analysis. Footprints, blood samples, strands of hair, fibers, tire tracks, strange substances, and so on can all contribute to the case. Collect all the information from the scene possible. You never know what will lead you to the suspect. Wear latex gloves when obtaining any evidence, and seal them in evidence bags. Make sure to pay attention to detail and do not overlook anything. Pay close attention to the places the suspect entered and exited the scene. After collection, evidence is taken to the lab to be analysed using certain tools.
