A private investigator is a person who conducts investigations, usually for a fee, on behalf of individuals or organizations. They often work to solve crimes, gather evidence, and uncover information that is difficult to obtain through traditional means. Private investigators may be hired by attorneys, businesses, or private citizens to investigate various matters such as fraud, missing persons, or infidelity cases. Their role involves collecting and analyzing data, conducting interviews, and observing activities in order to provide their clients with the information they need.
