Mr. Duff has experience in several areas of personal injury and wrongful death litigation, including the high-profile wrongful death Zeke Upshaw litigation against the NBA and Detroit Pistons.

Mr. Duff is also one of the attorneys representing the family of Nahje Flowers in a wrongful death case against the NCAA and University of New Mexico for the tragic and untimely death of a young student-athlete. Recently, Mr. Duff successfully argued against the NCAA‘s attempt to challenge the court’s personal jurisdiction in New Mexico federal court.

Mr. Duff is currently working on the Astroworld Festival litigation against Travis Scott and Live Nation for the wrongful deaths, severe injuries and PTSD of attendees for the deadly musical festival on November 5, 2021.

In 2019, Mr. Duff was part of the HMG trial team in a product liability case against Yamaha Golf-Car Company, involving a golf cart that tipped over on a child causing a severe traumatic brain injury. After four weeks of trial, the jury verdict returned a verdict of $33 million in damages.

In September of 2019, Mr. Duff tried a case with former HMG Partners John Martinez and Marion Reilly in Dallas County for an injured man who was hit by a drunk driver operating a company vehicle. The jury returned a verdict of $1,250,000.00 including $1 million in punitive damages.

In December of 2019, Mr. Duff tried a case with HMG attorney Alex Hilliard involving wrongful death in a premises liability case against I&R Trucking. Our client was the widow of Juan Perez, a trucker and handyman, who died after falling through a roof after his employer asked him to replace a rooftop skylight. Despite the employer’s knowledge of the dangerous hazard, which had existed on the roof for years prior to the incident, the employer willfully failed to provide Mr. Perez with any fall protection training, instruction, or equipment.

The jury in San Patricio County, Texas, a notoriously conservative county, unanimously agreed that I&R Trucking was grossly negligent for its callous disregard of the safety and welfare of its employee. After only three days of trial, the jury returned a record breaking $18 million verdict, including $10 million in punitive damages. The verdict remains the single largest wrongful death verdict in a premises liability case in the history of San Patricio County, Texas.
