Abstract: At 8:30 p.m. on November 6, 2014, an employee was operating a stock chaser on the third floor of a convention center rear hallway, while simultaneously towing a dolly to transport silverware and dishware. As the employee approached a set of double doors with a threshold, one of the dolls wheels became caught on the edge of the threshold. The employee attempted to catch the dolly; however, the dolly fell into the stock chaser. The employee's foot then fully engaged the accelerator, resulting in the stock chaser crashing through an elevator door and falling down the elevator shaft. The employee fell 20 feet, suffering a fractured wrist, fractured ribs, and contusions to his face and arms, which he was hospitalized. Despite receiving medical attention, the employee died 13 days later as a result of his injuries.
