How to Become a Private Investigator in Missouri

Missouri is nicknamed the ‘Show Me’ state, and there’s no profession that embodies this name quite like being a private investigator. When you work as a private investigator, you will be responsible for searching out hard to find information, and people, for your clients. For example, you may perform background checks or fraud research for a business, or track down a long-lost family member for an individual.

Missouri, like most states, has very strict requirements for working as a private investigator. If you are set on an investigative career, your first and most important step should be to learn about and fulfill these requirements.
