1. How computer databases and information networks are useful in criminal investigations.Over the past years, criminal investigations have been experiencing diverse challenges mainly related to the effective techniques and analysis. The use of computers database has developed rapidly especially in storing sophisticated software such as fingerprints. Information is considered an important component in enhancing the effectiveness of any criminal investigation. Indeed, there are hundreds of databases with information aimed at preventing and investigating crime. In this context, the databases contain records that can be accessed by the law enforcement agencies because the computer databases can be linked together to form large network systems (Brungs & Jamieson, 2010). Undoubtedly, the system can make a comparison of fingerprints to thousands of database prints within a short time and facilitates wireless access to the database by law enforcement communities.Information provided by third-party databases depicting information about an individual is also available to many law enforcement agencies. The major task of the law enforcement is to identify individual with preciseness. Moreover, the verification of the physical characteristics of the individual helps in accomplishing the investigation process. The fingerprints and photos techniques are used in getting more information about an individual with much ease. In this case, the scanned and digitized fingerprints are stored safely for further investigation. Consequently, the investigation greatly relies on the fingerprint technique in identifying the suspect involved in a crime. With the rise of DNA identification in the investigation, the DNA databases have propelled further investigation process. Such approach became a boost to criminal cases, therefore, facilitating a computer network with DNA database of different individuals. Arguably, the databases contain volumes of data that significantly culminates to the law enforcement agencies. Modern database management technology is considered to be the cornerstone amid the efficient and timely retrieval of data. The system contains links to several databases that are used in investigating crimes. 2. Describe and discuss crime analysis usefulness as a tool in criminal investigations.Law enforcement agencies are in pursuit of the effective strategies of identifying serial offenders. In this context, mapping and geospatial analysis are inculcated in assisting this process. The information gives specific information to the residents or police officers. Certainly, crime mapping is used by law enforcement agents in visualizing and analyzing crime patterns. For instance, the detectives use maps in identifying a crime pattern and hypothesize where the suspect might be living (Rossmo, 2014). Therefore, this approach helps in recognizing the most probable place of a suspect based on the analysis of crime locations. The mapping approach usually uses some sort of a color chart which makes crime investigations successful. Therefore, a hot-spot map of crime tends to give different information; such spots depicts the frequency of the crimes committed within a certain location. Different investigation approaches are used once the map analysis is substantively prepared. Eventually, the analysts use the information to aid in the criminal investigation. Presumably, the approach is considered useful in areas where crimes occur during a narrow period. Arguably, mapping and geospatial analysis have rendered law enforcement agencies helpful to society at large. Such approach does not directly solve cases but plays a vital role in managing large volumes of information. Therefore, it is appropriate for analytical techniques and maps. The investigation spectrum has gained much ground and success in handling crime cases amid the continuous incorporation of these analytical techniques.
