Representative Experience

  • Obtained a defense verdict in a premises liability case in which the plaintiff claimed to have slipped on water in clients’ convenience store, but clients maintained that the area was dry immediately following the accident.  The store’s surveillance video of the incident did not show the exact area where the plaintiff’s fall occurred, but we used the video to show the jury a frame by frame analysis of the plaintiff’s activities in the store prior to the accident. The plaintiff claimed to have sustained a left shoulder tear as a result of the accident and demanded $500,000. A unanimous jury verdict on liability was handed down after an hour and fifteen minutes of deliberation.
  • Brian had an amazing verdict for our client in a case where the plaintiff claimed he tripped and fell over a wheel stop as he attempted to enter the client’s store . Plaintiff sustained a fractured hip and underwent two subsequent surgeries each involving open reduction with internal fixation. A third surgery, a total hip replacement, was recommended by plaintiff’s orthopedic surgeon but had not been performed as of the date of the verdict. Plaintiff had a permanent leg length discrepancy as a result of the injury. The jury returned a verdict finding the plaintiff 90 percent at fault for the happening of the accident and found our client Speedway 10 percent responsible. The plaintiff’s activities inside and outside the store were captured on the store’s video surveillance system. We retained an imaging sciences expert to conduct a frame by frame analysis of the video which was shown to the jury by our trial technician. We also retained a civil engineer who testified that the wheel stop in question met all of the relevant safety requirements. The jury returned this remarkable verdict in less than one hour. Plaintiff had demanded $1,200,000 to settle prior to trial.
  • Obtained a defense verdict for our client after trial. The plaintiff claimed that she suffered second-degree burns on her right dominant hand resulting in permanent scarring as a result of spilling hot tea she had purchased. The plaintiff’s activities inside the store were captured on the store’s video surveillance system. We retained an expert to conduct a frame by frame analysis of the video which was shown to the jury by our trial technician. In addition, we retained a mechanical engineer with specific expertise in the areas of fluids and heat transfer. The last settlement demand was $300,000, no offers were made.
