Private detectives and investigators use many methods to determine the facts in a variety of matters. To carry out investigations, they may use various types of surveillance or searches. To verify facts, such as an individual’s place of employment or income, they may make phone calls or visit a subject’s workplace. In other cases, especially those involving missing persons and background checks, investigators often interview people to gather as much information as possible about an individual. In all cases, private detectives and investigators assist attorneys , businesses, and the public with legal, financial, and personal problems.

Private detectives and investigators offer many services, including executive, corporate, and celebrity protection; pre-employment verification; and individual background profiles. They investigate computer crimes, such as identity theft, harassing e-mails, and illegal downloading of copyrighted material. They also provide assistance in civil liability and personal injury cases, insurance claims and fraud , child custody and protection cases, missing persons cases, and premarital screening. They are sometimes hired to investigate individuals to prove or disprove infidelity.

Most detectives and investigators are trained to perform physical surveillance. They may observe a site, such as the home of a subject, from an inconspicuous location or a vehicle. They continue the surveillance, which is often carried out using still and video cameras, binoculars, and a cell phone, until the desired evidence is obtained. This watching and waiting often continues for a long time.

Detectives also may perform computer database searches or work with someone who does. Computers allow investigators to quickly obtain massive amounts of information on individuals’ prior arrests, convictions, and civil legal judgments; telephone numbers; motor vehicle registrations; association and club memberships; and other matters.

The duties of private detectives and investigators depend on the needs of their clients. In cases for employers that involve fraudulent workers’ compensation claims, for example, investigators may carry out long-term covert observation of subjects. If an investigator observes a subject performing an activity that contradicts injuries stated in a worker’s compensation claim, the investigator would take video or still photographs to document the activity and report it to the client.

Those who focus on intellectual property theft, for example, investigate and document acts of piracy, help clients stop illegal activity, and provide intelligence for prosecution and civil action. Other investigators specialize in developing financial profiles and asset searches. Their reports reflect information gathered through interviews, investigation and surveillance, and research, including review of public documents.

Legal investigators specialize in cases involving the courts and are normally employed by law firms or lawyers .

Corporate investigators conduct internal and external investigations for corporations. In internal investigations, they may investigate drug use in the workplace, ensure that expense accounts are not abused, or determine whether employees are stealing merchandise or information. External investigations are typically done to uncover criminal schemes originating outside the corporation, such as theft of company assets through fraudulent billing of products by suppliers.

Financial investigators may be hired to develop confidential financial profiles of individuals or companies that are prospective parties to large financial transactions. These investigators often are certified public accountants (CPAs) who work closely with investment bankers and other accountants. They search for assets in order to recover damages awarded by a court in fraud or theft cases.

Detectives who work for retail stores or hotels are responsible for controlling losses and protecting assets.

Store detectives also conduct periodic inspections of stock areas, dressing rooms, and restrooms, and sometimes assist in opening and closing the store. They may prepare loss prevention and security reports for management and testify in court against persons they apprehend. Hotel detectives protect guests of the establishment from theft of their belongings and preserve order in hotel restaurants and bars. They also may keep undesirable individuals, such as known thieves, off the premises.
