A journalist discovered a clamshell with white substance inside the propulsion system of the torpedo presented by the Joint Investigation Group as the decisive evidence in the sinking of the Cheonan.
The “Three Press Groups’ Verification Committee of the Results of the Cheonan Investigation,” composed of the Journalists’ Association of Korea, PD Assocation of Korea and National Union of Media Workers, said Wednesday that inside the second propeller in the back of the propulsion system, they found a piece of a bivalve shell, a clamshell. At the edge of the clamshell was white, flower-shaped substance, and the groups say this clamshell is strong evidence of the fact that the torpedo had nothing to do with an attack on the Cheonan. The committee claimed the white substance showed that the clam had been inside the propulsion system before excreting the substance. Prior to this, a blogger by the nickname of “Autumn Night” posted on the political webzine Surprise on Monday a zoomed-in photo and analysis of the clamshell, which was inside one of six 2cm holes in the central part of the screw.
