Police Detective Job Description
Police detectives, unlike police officers, don't wear a uniform, drive patrol cars, or patrol; instead, they spend much of their time compiling information and evidence for the cases they are assigned. They wear plain clothes, usually a suit and tie, and drive unmarked cars. Because police detective is a higher ranking and higher paid position than police officer, it requires more experience and knowledge.
Time spent as a patrol officer is usually mandatory before becoming eligible to pursue the position of detective. While a great deal of knowledge is learned on the job, further training and education in investigative techniques are required to make detective. This training and education are specified by the department that employs the aspiring detective. Much of a detective's time is spent on investigation and paperwork, but they are expected to maintain a certain level of physical fitness.
What does a Police Detective do on a typical day?
- Police detectives interview suspects, witnesses, and victims as they try to piece together the story of how the crime that they are investigating occurred.
- Detectives work closely with their jurisdiction's Crime Scene Investigation Unit (CSI), which gathers the forensic evidence police detectives need to work their cases. They will continue to work diligently on a case until it is solved or until they can go no further with the evidence and other information they have gathered.
- They may be called to testify in court using the evidence and information that has been thoroughly and meticulously collected and analyzed by the detective, the forensics unit, and its crime lab.
- Police detectives are like victim advocates, doing everything they can to get justice for them while keeping them appraised of the progress of their case.

- Financial & White Collar Crimes Detective
- Drug Enforcement Detective ( DEA )
General detectives do just as the name implies, general investigation, whereas the others specialize in certain types of crime. Homicide detectives focus on cases involving suspicious deaths. Once they rule a death is not by accident or suicide, but in fact a murder, they then proceed to delve further into the case and work until they either solve it or can go no further. They work closely with their CSI unit, which collects, analyzes, and reports the physical evidence, freeing up the detective's time to focus on suspects and witnesses.
Financial crimes detectives focus on the growing problem of white collar crime. While no one is physically harmed in the commission of a financial crime, victims are damaged or devastated financially. Financial and white collar crimes include fraud such as check or mortgage fraud, money laundering, embezzlement, identity theft, and bribery. Drug enforcement detectives handle illegal drug related cases involving drug trafficking, sales, and possession. They work primarily with their local department but team up with members of state and federal drug enforcement when necessary. The Drug Enforcement Agency (DEA) is a federal agency that enforces the laws and regulations of the United States concerning controlled substances. The DEA employs Agents, which is what usually comes to mind when thinking of the DEA, as well as Diversion Investigators, Chemists, Fingerprint Specialists, and Intelligence Research Specialists. Having detectives that focus on specific crimes helps cut down on having them spread thin, while allowing them to hone their skills in their specialty; thus, they are more effective in their jobs and have the ability to solve and prevent crime.
