What Private Detectives and Investigators Do[About this section] [To Top]

Private detectives and investigators search for information about legal, financial, and personal matters. They offer many services, such as verifying people's backgrounds and statements, finding missing persons, and investigating computer crimes.

Duties of Private Detectives and Investigators

Private detectives and investigators typically do the following:

  • Interview people to gather information
  • Search online, public, and court records to uncover clues
  • Conduct surveillance
  • Collect evidence for clients
  • Check for civil judgments and criminal history

Private detectives and investigators offer many services for individuals, attorneys, and businesses. Examples include performing background checks, investigating employees for possible theft from a company, proving or disproving infidelity in a divorce case, and helping to locate a missing person.

Private detectives and investigators use a variety of tools when researching the facts in a case. Much of their work is done with a computer, allowing them to obtain information such as telephone numbers, details about social networks, descriptions of online activities, and records of a person's prior arrests. They make phone calls to verify facts and interview people when conducting a background investigation.

Detectives also conduct surveillance when investigating a case. They may watch locations, such as a person's home or office, often from a hidden position. Using cameras and binoculars, detectives gather information on people of interest.

Detectives and investigators must be mindful of the law when conducting investigations. Because they lack police authority, their work must be done with the same authority as a private citizen. As a result, detectives and investigators must have a good understanding of federal, state, and local laws, such as privacy laws, and other legal issues affecting their work. Otherwise, evidence they collect may not be useable in court and they could face prosecution.

Skip tracers specialize in locating people whose whereabouts are unknown. For example, debt collectors may employ them to locate people who have unpaid bills.

Although investigators often work alone, some work with others while conducting surveillance or carrying out large, complicated assignments.

Private Detective and Investigator Training

Most private detectives and investigators learn through on-the-job training, typically lasting between several months and a year.

Although new investigators must learn how to gather information, additional training depends on the type of firm that hires them. For example, investigators may learn to conduct remote surveillance, reconstruct accident scenes, or investigate insurance fraud. Corporate investigators hired by large companies may receive formal training in business practices, management structure, and various finance-related topics.

Work Experience in a Related Occupation for Private Detectives and Investigators
