How To Become a Detective or Criminal Investigator

Detectives and criminal investigators conduct investigations related to suspected violations of local laws to prevent or solve crimes. Detectives and investigators perform various other types of surveillance or searches. To verify facts, such as an individuals income or place of employment, they may make phone calls or visit a subjects workplace. In other cases, especially those involving missing persons and background checks, investigators or law enforcement interview people to gather as much information as possible about an individual. Sometimes investigators go undercover, pretending to be someone else to get information or to observe a subject inconspicuously.
