Importance of CDR and Tower Dump analysis​

Call Detail Records (CDRs) and a building system dump analysis are components of modern law enforcement investigations and as such, assist in understanding the communication patterns as well as the movements across the area of the subjects under investigation.

Call Detail Records (CDRs)

The majority of telecommunications companies generate CDRS. CDRS in this case stands for the call detail records service It is worth note that CDRS contains information describing other phone calls made during the conversation, namely:

• Identification of the Caller and Receiver: Refers to ID of the customers who engage in a call.
• Date and Time: Refers to the information about when the call was made or when it started.
• Time of the Call: It indicates the period during which a call took place.
• Information on the Cell Towers Linkage: This relates to the information on the cell towers that were used to place the call as this may help in identifying where the device was located during the call.

From the analysis of CDRs, relationships can be built between different people, their movements and their actions. For example, the CDRs of numerous suspects can be assessed so as to determine whether the suspects have made calls to each other prior and after the commission of a crime. Using CDRs, evidences can be placed in line with cameras, texts and other sources to assist in the establishment of the time and address of the crime scenes. Such timeline identifies the main crime scene as well as all other locations where the crime took place.

Tower Dump analysis

CDR analysis is supplemented by tower dump analysis by including data from selected cell towers for a specified time frame. These include the following:

• Device Identifiers: This entails the information of all mobile devices that connected to a particular tower within a specific time range set.
• Location Data: Assists law enforcement in identifying which devices did the persons who were close to the scene of offense possess at relevant times.

The process of acquiring a tower dump formally starts with a police officer requesting or applying for a warrant together with legal instructions or a subpoena to telecoms service providers for the particular information. After obtaining such information, analysts can comb through this data in order to look for possible suspects or witnesses who frequented the area during crucial times.

Combined Use of CDR and Tower Dump analysis​ in Investigations

The combination of CDRs and the databases built through tower dump analysis provides investigators with the most lethal weapon. Such a combination makes it possible to:

• Enhanced Geolocation: Cross-checking the time of events recorded in CDRs with that of events recorded in the tower dumps systems, investigators can establish the location of people at certain specific times.
• Network Analysis: Through analysis of communication patterns of different individuals and how they are connected it is possible to establish criminal associations or conspiracies.
• Timeline Construction: Through the use of call records together with records of activity on towers, timelines of different events can be constructed in a manner which can provide or destroy alibis for people suspected of having committed crimes.

It has often been noted that the carrying out of these types of analyses is made easier through the use of complex software programs that allow for the automatic treatment and visual representation of data, which makes it easy for law enforcement officers to come up with very useful information from large volumes of data. This is a highly important feature especially in multi-faceted investigations on drugs, terrorism or serious crimes where valuable information is needed urgently.
