1. While enroute to crime scene, firt officer should be alert to possible suspects fleeing the scene. 2. Upon arrival, verify crime has been committed. If crime is in progress, remove any threats or contain threats until back-up arrives. 3. Assist victims (medical) and protect witnesses and bystanders. 4. Arrest perpetrator if at scene. 5. Identify witnesses. 6. Brief investigators.
If the victim(s) are still on the scene, check to make sure if there are any injuries or meidcal assistance is needed. THEN - get enough information to flash a lookout over the radio for the offender(s).
The first and most important step in any crime scene investigation is to secure the scene. It sounds easier than it really is. The scene includes possible witnesses, victims and suspects. Securing the scene includes keeping unauthorized personnel from cruising through the scene. The most common contamination results from police, ems, victims and witnesses. The best thing that can happen to a crime scene once it has been secured is, nothing.
Once the scene has been secured an interview of victims, witnesses and suspects will provide an overview of what to expect once inside the crime scene. The first responding officer will provide a lot of information on what was found upon arrival, what has been touched, moved or removed.
The next step is to "walk through" the scene to get an idea of the nature of the crime, how it was committed, point of entry and point of exit. The purpose of the walk through is to determine what needs to be more closely examined and what evidence may be present.
Once the safest route for traveling through the scene has been determined, it is time to photograph the scene. Photographs begin with the general to the specific. A picure of the parking area may be the starting point, with shots of exeterior walk ways leading to the scene following. All enry point to the scene need be photographed concentrating on the suspected point of entry. The exterior shots should present a travelogue of how acess to this scene was had. Once the exterior shots have been completed the interior shots begin. Once again we start with the general before we concern ourselves with the specific. Rooom entryways, layouts points of access, contents and furnishing provide a panorama of the enterior and will tell part of the story to the jury of what took place and in what order it happened. T
Once the general pictures have been taken, picutures of evidentiary items are next. All photos should be taken ninty degrees to the surface of the object being photographed. All evidence should be photographed in place as found first and later with evidentiary markers and if necessary something to assist in determining the size of the object such as a ruler, pen, coin etc. A photographic log is kept identifying each picture and the sequence in which it was taken.
Once all photos have been taken it is time to measure and sketch. Every evidentiary item must be geographically located (measured) and sketched in a field drawing. The drawing can be further refined later.
The final steps involve the handling and packaging of all evidence. Each piece comes into evidence at a specific time. That time begins the chain of custody of that piece of evidence. Police are responsivle for accounting for each piece of evidence that comes into their possession, for every minute it is in their possession.
The evidence will find its way to the laboratory or the evidence room where further entries are made to maintain the chain of custody.

The scene of a crime in the first instance is usually investigated by a constable who has responded to a call to attend the scene. His job is to take down details of the crime and statements from witnesses. It is also his job to preserve the crime scene until the Scenes of Crime Officer (SOCO) arrives to take over the investigation.
