Each crime that is committed, while the crime itself may be individual in nature, can be investigated by breaking it down and using the same step by step process. An example of this process in action could be the string of daytime robberies which have been occurring in one area of City X. They can be investigated by using these steps as the basis for the creation of a strategic operational plan which can be followed by the investigating officers to ensure a complete and comprehensive analysis and determine if there is a pattern or if these robberies are even connected. The plan would look something like the following:

The first step in the investigation should be to identify and review each case and determine whether all pertinent information about each robbery was gathered (i.e. time of incident, description of perpetrator(s); such as height, weight, hair color, clothing, speech patterns. Any information that may be useful to the investigation should have been considered and recorded). The second step would be to conduct second interviews of each of the store owners and possible witnesses to each crime, if there are any new facts about the cases or to determine if there is any false reporting. Doing this can help us to determine the M.O. (Modus Operandi) of the perpetrator(s) (TheIACP.org, 2014).

Step three in the investigation is the assigning of the specialized investigative tasks to certain individuals. Such specialized tasks may include, but are not limited to, fingerprint identification, video recording analysis to clean up surveillance tapes in an effort to better identify possible suspects, and officers conversant in an ethnic language to better interact with any non-English speaking peoples 汽車跟蹤器 who may be the victims or witnesses of the crimes. By making note of who the task was assigned to, when it was assigned and when it was completed, it will help to keep the investigation organized and easy to manage. There will not be people “tripping over each other”, so to speak.

Next, we will need to look at each piece of evidence that has been gathered at each individual scene and group them together by type of evidence (photo, video, interview, witness statement, physical evidence, etc.), date of incident, and proximity to other robberies, time of day, etc. The pieces of evidence that are similar to other crimes are placed into a group and those that are different would be placed into a separate group to be looked at later in the investigation. This fifth step in the investigation will aid in the determination of which robberies could be linked to the same perpetrator or perpetrators. Once all of the information has been identified, the facts from each robbery will need to be grouped together to create a “picture” of the event. This picture will attempt to lay out the sequence of events or timeline.

To further aid in creating the “picture”, the sixth step would entail securing any and all video surveillance tapes of the crime scene if they are available. From them, we could possibly obtain information that could possibly aid us by capturing images of the thieves in the process of the commission of the crime. If possible, it would also assist if tapes from surrounding businesses could be obtained as they may show the perpetrator(s) prior to or after the commission of the crime. In order for us to garner the tapes, requests must be made of each business which may have visual records. If a business refuses however, we would first need to get search warrants in order to obtain video records for the dates and times of the robberies.

With the tapes in hand, including any that required search warrants to obtain, we would then provide them to a team of specialized investigators would need to go over each tape and make note of any suspicious activity before and after the crime, as well as taking note of anything that may identify the thieves during the commission of the crime. An example of this could be something as simple as a tattoo made visible by a sleeve pulling back when a thief is reaching for the cash. When comparing information from different crimes, this can also aid in the determination of which individuals to take a closer look at. Are there certain people who appear in each of the areas at the time of the crimes? These would be the people to make a special note of and add to the list of suspects to question. Step Seven would be the interviewing of these suspects (HR.BLR.com, 2007).
