Ahn, who is believed to be a newborn baby, was found at a park in Danwon-gu, Gyeonggi Province on November 11, police said.
The park manager found the body in a pink bag next to the public restroom near the outdoor stage and reported it to the police.
The corpse was found to be in a state where corruption was underway at the time of the discovery and the shape could not be recognized. There was a ladies' underwear in the bag.
The park manager told the police "I saw a bag lying 10 days before the public toilet. I opened the bag and I saw the body and reported it to the police. "
A police official said, "Corruption is severe," he said.
