Police Detective Job Description
Police detectives investigate crimes and collect the evidence needed to put criminals behind bars. The field is an excellent choice for anyone with a background in law enforcement and an eye for detail. Detectives may work alone or with others, and due to the nature of the field, many work irregular hours in dangerous environments. Police detectives may report to a higher-ranking officer on a regular basis.
Police Detective Duties and Responsibilities
Police detectives investigate crimes for police departments across the country, but they may also engage in other activities. These activities may vary from department to department, but in general, most police detectives are responsible for performing the following tasks:
Collecting evidence is a very important part of a police detective’s job. Criminal evidence must be obtained in a certain manner to ensure its integrity or it may not be admissible in court. Police detectives collect and store the evidence in a manner that preserves its integrity.
Police detectives interview potential witnesses as well as perpetrators to gain information about crimes. The content of their interviews may be used in court, as long as the interview was conducted in a legal manner. They may travel to other locations or perform interviews at police stations and jails.
Police detectives often watch criminals engage in crimes in hopes of collecting video or audio evidence. These surveillance operations are often complex, and they may even involve former criminals or those close to the perpetrators. As with other types of evidence, the evidence obtained during surveillance operations is often admissible in court.
Search Public and Private Records
To find out more about a potential perpetrator, a police detective may search public or private records. They may even perform background checks to learn more about certain individuals. The information they obtain from public criminal, professional, and medical records is used during the course of the investigation.
Turn Over Evidence to Attorneys
Police detectives work closely with prosecutors and district attorneys to prove a person is guilty of a crime. They must turn any evidence they collect over to all attorneys involved in the case, including the defendant’s defense attorney.
Police Detective Skills and Qualifications
The skills and qualifications needed to become a police detective vary from place to place; however, a college degree is usually not required to enter the field. Police departments often seek detectives who possess the following skills and abilities:
- Investigation skills – a successful police detective should be well-versed in common investigational techniques. They should be capable of collecting the evidence needed to prove a person committed a crime
- Legal knowledge – police detectives do not need to obtain a JD, but they must have basic knowledge of the legal system. If they do not collect evidence legally, they can be fired or prosecuted themselves, and the evidence they collect will not be used in court
- Law enforcement background – most police detectives start out as police officers. This is not technically required, but most departments desire candidates with a background in law enforcement
- Problem-solving skills – to be successful as a police detective, one must have exceptional problem-solving skills. Detectives should be capable of understanding the significance of evidence and using it to catch suspects
- Attention to detail – police detectives must be capable of picking up on subtle human behaviors and reading between the lines
Police Detective Education and Training
As mentioned previously, a college degree may or may not be required to enter the field by some police departments. Those that do require a degree often prefer individuals with a two- or four-year degree in a discipline such as criminal justice, but this is rare. Most private investigators have a background in either law enforcement or the military, and once they are hired, they receive a significant amount of on-the-job training that sometimes lasts up to a year. Many retired police officers choose to become private investigators later.
