McKinnon Investigative Group provides licensed private investigation services across Key Largo and all of Monroe County.
Memberships & Affiliations
Key Largo sits at the northern gateway to the Florida Keys, making it the most accessible island in the chain and the first point of entry for investigative cases that originate in Miami-Dade but involve subjects or assets in Monroe County. That geographic position creates a distinct cross-jurisdictional case profile that requires familiarity with both the 11th and 16th Judicial Circuits.
The Ocean Reef Club, one of the most exclusive private residential communities in the United States with over 1,700 residences and its own airport, generates a consistent volume of high-net-worth domestic investigations, asset discovery cases, and background screening requests that are unlike anything found elsewhere in Monroe County. Access restrictions and the community’s private security infrastructure require a particular approach to investigative work in and around Ocean Reef.
Key Largo’s dive tourism and charter fishing industries produce their own investigative case types — workers compensation claims from marine industry employees, vessel fraud, charter business disputes, and personal injury cases involving diving accidents. These case types feed a specific segment of the 16th Judicial Circuit’s civil docket that McKinnon Investigative Group has handled for decades.
The area’s significant seasonal population, many of whom maintain primary residences in the Northeast, adds a layer of asset discovery and domestic investigation complexity driven by part-time residency and multiple-jurisdiction financial structures.
Key Largo’s combination of a seasonal high-net-worth population, a working marine industry, and the Ocean Reef Club community creates demand across several investigative case types. McKinnon Investigative Group handles the full range of personal, legal and corporate investigations across the Upper Keys.

Domestic investigations in Key Largo are shaped by the island’s seasonal population. Many residents maintain primary homes in the Northeast and spend part of the year at properties along US-1 or within private communities including Ocean Reef Club. Infidelity, custody, and asset discovery cases here frequently involve multi-jurisdiction financial structures and part-time residency patterns that require an investigator familiar with both Monroe County and the originating jurisdiction.
Marine industry investigations cover workers compensation claims from dive charter and commercial fishing employees, vessel fraud, charter business disputes, and personal injury cases involving diving accidents at John Pennekamp Coral Reef State Park and the surrounding reef system. These cases feed a specific segment of the 16th Judicial Circuit’s civil docket.
Seasonal resident cases often involve background screening for household staff, due diligence on local business investments, and asset discovery for high-net-worth individuals whose financial interests extend well beyond Monroe County.

Yes. Hiring a licensed private investigator in Key Largo is entirely legal under Florida Statute 493. One important distinction for Keys residents and businesses: Monroe County operates under the 16th Judicial Circuit, which is geographically isolated from the mainland court system. Evidence gathered in Key Largo must meet the same Florida evidentiary standards as anywhere else in the state, but the practical logistics of court filings, depositions, and testimony in Key West require an investigator familiar with 16th Circuit procedures. McKinnon Investigative Group has worked within the 16th Judicial Circuit for over 30 years.
Yes. All evidence gathered by McKinnon Investigative Group is collected in full compliance with Florida law and prepared specifically for admissibility in the 16th Judicial Circuit Court, which covers all of Monroe County. For cases involving Ocean Reef Club we take additional care to ensure all evidence is gathered from publicly accessible areas and in full compliance with both Florida law and the community’s access policies. Evidence gathered incorrectly in a private community setting can be challenged in court regardless of what it shows.
Private investigator costs in Key Largo vary by logistics. Rates differ between surveillance in the underwater wonders of John Pennekamp Coral Reef State Park or the exclusive estates of Ocean Reef Club versus background checks. We provide transparent estimates for residents.
Yes. McKinnon Investigative Group works regularly with attorneys handling cases in the 16th Judicial Circuit, including family law matters, civil litigation, and personal injury cases involving marine industry employees and tourists.

We have experience operating across the 11th and 16th Judicial Circuits on cases that originate in one county and involve subjects or evidence in the other.
