SOUTH FLORIDA   /   INVESTIGATIVE SUPPORT FOR ATTORNEYS

Personal injury investigations in South Florida

Who saw the impact? Which camera faced the entrance? What did the property look like before the repair? Investigative Services Unlimited Group (ISUG) helps personal injury attorneys answer questions like these in Miami-Dade, Broward and Palm Beach counties.We locate witnesses, document scenes and organize records so counsel can see what the available evidence supports and what still needs checking.

Motor vehicle crashes: finding the missing view

After a collision involving a private car, delivery van, rental or fleet vehicle, two drivers may remember the same turn differently. We can visit the intersection, photograph each approach, ask nearby businesses about cameras and speak with willing witnesses. If a company vehicle was involved, we can identify who holds dispatch records or video so counsel can direct a preservation request.

Falls and other premises injuries

At a store entrance or parking lot, a later visit may show a new mat, a repaired curb or different lighting. We date our photographs, record where each was taken and distinguish what we observed from what witnesses remember about the day of the injury.

What counsel receives

  • Witness summaries: who was reached, where each person was positioned and what they recall firsthand.
  • A photo and video log: the source, date and location of available material, plus cameras checked and footage still outstanding.
  • A case chronology: a sequence of events tied to its sources, with conflicting accounts and unanswered questions clearly marked.
