Hired by individuals or law enforcement organizations, a private investigator is responsible for conducting background checks, processing and delivering legal documents such as subpoenas, locating missing persons or using an electronic medium to track down incriminating evidence. A private investigator’s job involves having a keen eye for detail and specifications so that any missing detail can be easily spotted. The service they provide usually involves a hefty amount of money because it is not easy to perform the job that they have. They often put themselves out in front of the most daunting situations, where their own lives are in danger. Private investigators may charge a high fee for their services.
