The fundamental positive characteristics of a criminal investigator are those that will help the investigator to do their job to the best of their ability. According to Hess and Orthmann (2010), “A good investigator is knowledgeable, creative, patient and persistent. Regardless of title, pay or rank, investigative officers are more effective when they possess specific intellectual, psychological and physical characteristics” (p. 12). Some characteristics, in addition to the above,that an investigator should have is being open minded to all the possibilities, logical and have empathy. Two examples of investigators from television that are shown to exhibit these traits are Richard Castle from Castle and Gil Grissom from CSI. Both these characters from popular crime television shows investigators are knowledgeable about a wide variety of topics, both show creativity in their own particular way, such as designing lab experiments and spinning possible stories for finding a motive, and they continue working towards finding the solution even when the show writers throw blocks in their path.
Negative characteristics of a criminal investigatorwould be the opposite of the characteristics that are positive, taking the positive characteristics too far or only having a few of the characteristics. For instance, a detective that is too persistent that never gives themselves a chance to get away from work and be with family or their friends may get too burnt out over time to be an effective investigator. An example of this could be Aaron Hotchner during the middle seasons of Criminal Minds where his relationship with his wife suffers from his devotion to his job. Also, a detective could get to the point where they are no longer open-minded and start to have a lot of preconceived notions like Olivia Benson on SVU.

Training investigators to have specific expertise may be easy for large cities to handle because they have a large amount of officers to call upon for crimes. According to Palmiotto and Unnithan (2010):
For example, in police departments, clear distinctions are made with regard to those who are defined as patrol officers and those who are deemed to be investigators. The latter are often subdivided into units that deal with crimes against persons and those who investigate property crime. (p. 80-81)
The problem is that smaller cities may not be capable of doing the same. The main con of training two of the investigators specifically in homicide investigation would be that it would take that manpower away from other crimes. Eventually, the rash of homicides may be eliminated, and having two out of five officers specialized in this type of investigation would be too many. The pro of training two of the investigators in this specifically would be that it seems that this is a problem crime in the area, and having two investigators may increase how quickly these violent crimes are solved. The two officers may be able to assist each other with their investigations when a second set of eyes are needed more efficiently than those that are not specifically training for homicide investigations. Overall, if the rash of homicides is a large enough number in comparison to other crimes in the area it seems that the pro will outweigh the con in training two officers specifically for homicide.
