The chief of the National Forensic Service, which handled the DNA analysis of a body discovered on June 12, on Thursday said he is "100-percent confident" the corpse is that of ferry owner Yoo Byung-eon.
Seo Joong-seok told a parliamentary hearing that there is "no possibility" that the body is someone else's.
Seo said DNA analysis turned up a perfect match with those of Yoo's older brother in both paternal and maternal lines. He added that teeth samples and other physical traits were identical to Yoo's.
"There is almost no chance of error," he added.
Answering rumors that the body found in a field 2.5 km away from the cottage where Yoo was hiding in southwestern Korea may belong to his half-brother, Seo said the brother's DNA would have different maternal traits.
When asked how Yoo's body could have decomposed so badly over a two-week span, Seo said, "Although the body was decomposed, its muscles were intact and the limbs were still in place. The decomposition exposed his bones, because his organs and soft tissue were gone, but the process had not progressed down to the skeleton," as some press reports claimed.
Seo said he also obtained Yoo's dental records, which exactly matched those of the body. DNA samples were also discovered on the alcohol bottles found next to Yoo, but more analysis is needed.
