Memberships & Affiliations
Led by Francois McKinnon, a licensed South Florida investigator with over 30 years of field experience, McKinnon Investigative Group has handled cases across Martin County and the Treasure Coast since 1994.
Stuart’s position as Martin County’s county seat means it sits at the centre of the 19th Judicial Circuit’s legal activity for the mid-Treasure Coast. Cases originating anywhere in Martin County, from Sailfish Point to Palm City to Jensen Beach, move through Stuart’s courts, making local investigative familiarity essential for attorneys and private clients alike.
Stuart’s combination of a high-net-worth retiree community, a working marine and construction industry, and a growing business corridor creates demand across several investigative case types.

Domestic cases, marine industry investigations, and litigation support for the 19th Judicial Circuit in Stuart require an investigator who knows Martin County. Call us at (954) 513-7414 or use the form below to discuss your case confidentially.
Stuart’s identity as the Sailfish Capital of the World reflects its deep connection to the St Lucie River, the Indian River Lagoon, and the marine industry that has defined this community for generations. That marine economy produces a specific investigative case profile; workers compensation claims from boat crew and marina employees, vessel ownership disputes, charter business fraud, and personal injury cases involving waterway accidents.
Beyond the marine industry, Stuart’s significant retiree and second-home population, many from the Northeast attracted by Martin County’s consistently high quality of life rankings, generates domestic investigations, asset discovery cases, and background screening requests. Sailfish Point, the ultra-exclusive barrier island community with its own private airport, marina, and golf course, represents one of the most distinctive investigative environments in the McKinnon portfolio: high-net-worth residents, restricted access, and a level of discretion that every case requires.
Martin County’s historically low crime rate and strong property values attract a growing permanent professional population whose investigative needs span corporate fraud, employment background checks, and civil litigation support.
Stuart is the county seat of Martin County and home to the 19th Judicial Circuit Court, which covers Martin, St Lucie, Okeechobee, and Indian River counties. As the legal hub of the mid-Treasure Coast, Stuart’s courts handle a substantial volume of family law, civil litigation, and criminal defense cases that require professional investigative support.
McKinnon Investigative Group works directly with attorneys handling cases in the 19th Judicial Circuit, providing court-ready surveillance reports, time-stamped video evidence, sworn affidavits, and deposition testimony. Our familiarity with Martin County’s legal community and court procedures means attorneys get investigative support that integrates cleanly with their case strategy.
For family law attorneys in particular, Martin County’s active family court docket, driven by the area’s significant second-home and seasonal resident population, produces a consistent demand for domestic investigation, child custody documentation, and asset discovery that we have handled across the Treasure Coast for over 30 years.
