No two cases are the same. We adapt our approach to your objectives.
Our team brings an elite level of training and insight to complex investigations.
Port St. Lucie's explosive growth from under 200,000 residents in 2020 to nearly 260,000 today has created a booming insurance defense market. New residential construction, a large healthcare employment sector, and an influx of new residents from other states drive consistent workers' compensation fraud, personal injury defense, and domestic investigation caseloads. Our investigators work regularly with Port St. Lucie's 19th Circuit family law attorneys and insurance defense counsel.
Fort Pierce as the county seat handles all 19th Circuit court filings for St. Lucie County, making it the hub for litigation support work. The city's working waterfront and commercial fishing industry also generates marine insurance cases and vessel fraud investigations that differ from the residential profile of Port St. Lucie. Fort Pierce's older, more established community also produces estate dispute and financial elder abuse cases requiring discreet investigation.
Western St. Lucie County's agricultural operations — citrus groves, nurseries, and farm labour operations — generate a specific category of workers' compensation fraud and agricultural business due diligence cases. These investigations require field investigators with experience in agricultural property environments and an understanding of the labour law landscape that governs farm operations in the 19th Circuit.
One of the fastest-growing counties in the United States, St. Lucie County’s explosive residential expansion — the 5th largest population increase in the nation in 2023 — 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.
