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.
