At the first autopsy of the family of Yuna Jo (10), who was found dead in the sea, the exact cause of death could not be determined.
Police plan to test their bodies for plankton to determine if they died before or after drowning.
According to the Gwangju Nambu Police Station today (30th), the autopsy doctor of the National Forensic Research Institute who performed an autopsy on three bodies identified as the Chaoyang family gave a verbal finding that the cause of death was unknown.
He added that he could not be conclusive, but that drowning was also not ruled out.
It is said that the cause of death could not be determined because the body had been submerged in water for a long time.
No signs of her trauma or disease were found.
In order to determine the exact cause of death, the police plan to conduct a plankton test and drug and poison tests in the body.
Testing for plankton in the body can tell if the deceased died before or after drowning.
The results of the comprehensive examination are expected to take about a month.
In addition, the family's vehicle, which was salvaged from the sea yesterday, is also planning to check whether there is a fall accident or a mechanical defect through the National Forensic Service.
On the 30th of last month, the family of Cho and Yang left a pension in Sinji-myeon, Wando-gun by car at around 11 pm on the 30th of last month, and 6 minutes later, heading to the breakwater near Songgok Port, 3 km away, was captured on a closed circuit (CC) TV screen.
