Abstract: Between 10:15 p.m. and 10:30 p.m. on February 20, 2005, Employee #1, a municipal civil engineering associate, was standing in approximately three feet of rainwater, attempting to unhook a hose from a pump truck. The truck was originally located about 30 ft from the north edge of a large sink hole, which had eroded over a period of three days to approximately 30-ft deep by 100-ft wide by 100-ft long. Erosion of the street over a period of several hours had rendered the edge of the hole closer to the truck. Employee #1 fell down, was swept into the rainwater, and then downstream into the sinkhole. Nearby coworkers attempted to find Employee #1, without success. Emergency responders recovered Employee #1's body from the bottom of the sinkhole. He had sustained head trauma and blunt-force injuries, and was pronounced dead at the scene.
