Countries Where We Have Conducted Investigations
One of the fastest-growing cities in the United States, Port St. Lucie recorded the 5th largest population increase of any county in the nation in 2023. This explosive residential expansion has created a rapidly evolving investigative landscape driven by insurance defense, domestic cases, and the corporate fraud that follows rapid economic development.
Our investigative team maintains a deep operational presence across these primary St. Lucie institutions. We leverage these facilities to conduct on-site records research, file legal documentation, and coordinate jurisdictional field operations.
In the state of Florida, there is no legal distinction between the two terms; both refer to professionals licensed under Chapter 493 to conduct investigative services. While “private detective” is a more traditional term often used in popular culture, “private investigator” is the official designation used by the Florida Department of Agriculture and Consumer Services (FDACS). At McKinnon Investigative Group Inc., we fulfill all state requirements to carry this professional title.
