SEOUL: A diver died on Tuesday while working at the scene of South Korea’s ferry disaster as investigators disclosed that the ship was routinely overloaded with cargo to make more money. Lee Gwang-Wook, 53, suffered breathing difficulties after reaching a depth of 25 meters (82 feet), said coastguard spokesman Ko Myung-Suk. The 53-year-old, who was making his first dive at the scene, lost consciousness and was pronounced dead in hospital. Lee lost contact with surface controllers after five minutes in the water. He was the first victim among scores of divers engaged in the grim and dangerous task of finding and retrieving bodies from the sunken ship, while fighting strong currents and low visibility in silty water.
