What Does a Homicide Detective Do?
Some law enforcement agencies have a group of detectives dedicated to major crimes, such as homicide. In smaller departments, detectives work on all kinds of cases. These detectives, who handle a variety of non-specialized crimes, are often referred to as “line detectives.'' Usually these detectives are assigned cases as they come in by a supervisor through “the wheel,” or by rotation. It’s not uncommon to hear “Who’s up next on the wheel?” as these cases come in.
The line detectives are proficient in interviewing victims, witnesses, and suspects, as well as photographing and processing evidence at crime scenes. They also may prepare documents for court cases and testify in court.
Larger agencies have specialized units dedicated to specific kinds of crimes, such as sex crimes, financial crimes, narcotics, or homicide.
Homicide Detective Requirements
In almost all cases, homicide detectives work their way up through the ranks of their law enforcement agencies, and almost all law enforcement agencies require a college degree. See more detail below.
Steps to Becoming a Homicide Detective
Step 1: Obtain a college degree.
Majoring in Criminal Justice — and choosing a program at a college or university that offers both classroom and experiential learning — will help set you up for success in the field.
Step 2: Attend a police academy.
This is a necessary step to becoming a police officer.
Step 3: Pass relevant tests.
Candidates must pass a physical agility test, a written examination, and in most cases, successfully pass an oral interview with the law enforcement agency that is hiring them.
Step 4: Gain experience as a police officer.
After graduating from the police academy and securing a position in law enforcement, a police officer will serve on the streets, working with suspects and victims. This is crucial on-the-job training where an officer’s academic learning is molded by experience. Learning how to interview people and deal with difficult situations is an integral part of becoming a good law enforcement officer.
Usually, a police officer has extensive experience working on the streets before they become a detective. Different law enforcement agencies have different procedures for becoming a detective. In many agencies, it is done through a testing process and is considered a promotion. Other agencies require an interview process.
Skills Needed to Become a Homicide Detective
Homicide detectives are frequently chosen because they have demonstrated their ability to solve difficult cases in other detective units that they have served in. Continual training is needed to keep up-to-date with new techniques and legal requirements. It is necessary for detectives assigned to special units to have additional and periodic training specific to the type of crimes they are investigating and the techniques and tools used to investigate those crimes. Tools and techniques are continually evolving and changing, so a good detective must stay current with those tools and techniques. DNA, computer and mobile phone data retrieval, and cellular phone tracking are all areas that are changing and evolving.
In general, successful homicide detectives have strong problem-solving and communication skills, the ability to work under pressure and in high-stress situations, and a passion for helping the community. This line of work is not for the faint of heart; candidates will need to be able to stomach whatever you might encounter at a crime scene.
