Sinking of MV Sewol

On the morning of 16 April 2014, the ferry MV Sewol sank while en route from Incheon towards Jeju City in South Korea. The 6,825-ton vessel sent a distress signal from about 2.7 kilometres (1.7 mi; 1.5 nmi) north of Byeongpungdo at 08:58 KST (23:58 UTC, 15 April 2014). Out of 476 passengers and crew, 304 died in the disaster, including around 250 students from Danwon High School in Ansan. Around 82% of the Sewol's casualties were children and out of the 172 survivors, more than half were rescued by fishing boats and other commercial vessels that arrived at the scene approximately 40 minutes before the Korea Coast Guard (KCG).

The sinking of Sewol resulted in widespread social and political reaction within South Korea. Many people criticized the actions of the ferry's captain and most of the crew. Also criticized were the ferry's operator, Chonghaejin Marine, and the regulators who oversaw its operations, along with the administration of President Park Geun-hye for her response to the disaster and attempts to downplay government culpability, and the Korean Coast Guard for its poor handling of the disaster, and the perceived passivity of the rescue-boat crew on scene. Outrage has also been expressed against the initial false reporting of the disaster by the government and South Korean media, who claimed everyone aboard had been rescued, and against the government for prioritizing public image over the lives of its citizens in refusing help from other countries, and publicly downplaying the severity of the disaster.

On 15 May 2014, the captain and three crew members were charged with murder, while the other eleven members of the crew were indicted for abandoning the ship. As part of a government campaign to manage public sentiment over the official response to the sinking, an arrest warrant was issued for Yoo Byung-eun (described as the owner of Chonghaejin Marine), but he could not be found despite a nationwide manhunt. On 22 July 2014, the police announced that a body found in a field in Suncheon, roughly 290 kilometres (180 mi) south of Seoul, was identified as Yoo.
