Abstract: At 6:00 a.m. on July 31, 2014, a 29-year-old male plumber was working for a firm that provided janitorial services. He had been acting as the lead for a crew of five workers. The workers were subcontractors who had worked a late shift the day before, July 30, 2014. The shift had ended at approximately 9:00 p.m. Based on interviews, the employee was conducting a final walk around the building prior to leaving that evening. On July 31, 2014, at approximately 6:00 a.m., the employee was found by a coworker in a remote area. The employee was unresponsive and pinned under a set of six acrylic panels. Each panel measured 1.8 meters by 2.4 meters by 13 millimeters (6 feet by 8 feet by 0.5 inches) and weighed approximately 60.8 kilograms (134 pounds) each. The employee had been killed due to suffocation and there were no witnesses to the incident.
