Sinking Time

On a night in early winter when the sea fog would not lift, Jung Man-ho—a diver with twenty-five years' experience conducting nighttime underwater inspections of submerged structures—was hauled up to the deck of a support barge moored at Haeryang Harbor's quay wall and collapsed shortly after. The cause of death was not drowning. He had been brought to the surface in one pull, skipping every planned decompression stop he should have made on the way up, and was pronounced dead roughly thirty minutes after being laid on deck. Earlier that day he had announced he would submit to the authorities the next morning a copy of ledgers he had been cross-checking for months from a labor-placement office. The dive-support barge remained in normal operation after the incident, and several hands had access that night to the deck control panel where the buttons to start and stop machinery were clustered. Interrogate the five people entangled in this death and determine whose hand pulled him up that way.

The Empty Dock

At Haeryang Shipyard's Dry Dock No. 3 lower inspection passage, subcontractor insulation worker Kang Yun-do was found submerged. That night he was on the lower-level work roster assigned by a labor-placement office, and for days he'd been threatening to report that office's ledgers to the authorities. The dock was still in normal operation right up to the incident, and after the lower level was logged as 'unoccupied,' the scheduled flooding sequence began exactly on time—a process that always checked for personnel first, but that one time ran with a man still inside. Interrogate the five people entangled in this death and determine whose hand locked the lower passage door that night.

Venting Complete

Haeyang Port has a cargo handling yard where freight is unloaded and reloaded, and within it a fumigation zone where insects are killed with poison gas. In that zone, Bae Seung-won, assigned as a container-opening inspection witness to open containers and remove cargo during the night shift, was found collapsed inside an import cargo container and died after transport. Cause of death was acute poisoning from inhaling residual fumigation gas remaining inside the container. That morning he had said he would report the books of the labor placement office that had put him on site to the authorities, and that very night he was assigned to witness the opening of that particular container. The door already bore a placard reading "Venting Complete," indicating residual measurement had been finished; he flipped the placard with his hand to confirm it, then walked in of his own accord. The fumigation zone was operating normally at that hour. Interrogate the five people entangled in this death and determine whose hand hung that placard without verification.

Preheat

At a seafood processing plant in Haeyang Harbor's industrial zone—where product is boiled or steamed to cook—Moon Sang-jun was assigned to clean and inspect the inside of a tank on the night shift. When the first preheat cycle of the steaming line started early in the predawn hours, he was exposed to high-temperature steam and died. That night the midnight equipment startup was triggered ahead of schedule, and the indicator showing a person was inside the tank was lit on the control screen at the time. The line remained in normal operation until just after the accident, and there was no malfunction or maintenance defect in the steam system—only one confirmation step that should have been taken before startup was skipped. Interrogate the five people involved in this death and determine whose hand started that preheat.

Night of Guarantee

In the basement document vault of Shinduk Labor, a dockside labor-placement office, the body of Heo Jae-ung—a labor and surety-bond compliance auditor commissioned by the Port Authority to verify that work was done by the book—was found dead. It was a late-night in early winter, sea fog blanketing the wharf, and the cause of death was mechanical asphyxiation by nasal and oral occlusion. Drag marks remained in the dust on the vault floor, and a pile of waterproof sacks had been disturbed, yet the emergency-alert terminal on the vault wall had sent no outgoing signal, and the report came in only five hours later. He had been digging into labor and surety-bond practices at four subcontracted sites—diving, shipbuilding, quarantine, and processing—and was hated everywhere, but everything he pointed out was always correct; he was the only external check that could see into this office. That late night was the final audit interview stipulated by contract. Interrogate the five people who were in the building that night and determine who brought him to his death.
