"In summarising the investigation result, the dead body found in Suncheon can be confirmed as Yoo Byung-eun. Even though we tried to investigate various causes of his death, the NFS could not find out the exact cause of Yoo's death under the given circumstances."

"This is a summarisation of the investigation result from the autopsy room. No unusual toxic substances were found in the liver-lung muscle, but a bit of alcoholic substance was found. However, it was below the general concentration level that can be found in ordinary decaying tissue."

"We, forensic scientists, say it is absolutely possible that the body can be reduced to skeleton, more precisely decomposed, in such a short period of time. Therefore it can be said that this matter should not be a controversy even among yourselves."
South Korea's state-run forensic lab said on Friday it had failed to find why a fugitive billionaire, blamed for April's Sewol ferry disaster, had died.
Police said earlier this week that a badly decomposed body found in rural South Korea last month had been identified as that of Yoo Byung-eun.
Authorities had been looking for the 73-year-old, believing he owned the sunken ferry, and that his alleged corruption may have contributed to the disaster.
The state-run National Forensic Service said on Friday that Yoo's body was too badly decayed to determine whether he died of disease.
April's disaster, the worst in South Korea in decades, left more than 300 people dead or missing, mostly high school students.
