The main job of private investigators and some private detectives is to obtain information and locate assets or individuals.
Some private detectives protect stores and hotels from theft, vandalism, and disorder.
Private detectives working as general investigators have duties ranging from locating missing persons to exposing fraudulent workers' compensation claims. Some investigators specialize in one field, such as finance, where they might use accounting skills to investigate the financial standing of a company or locate funds stolen by an embezzler. About half of all private investigators are self-employed or work for detective agencies. They may obtain information, interview witnesses, and assemble evidence for litigation or criminal trials. They get cases from clients or are assigned to cases by the owner or manager of the firm.
