Who is the murderer of the Korean drama Monster?

So many bodies appeared in the deer farm, and then Li kept saying that there were many women talking around him and her mother was helping him hide, so her mother said that she was an intelligence agent and wouldn't get her hands dirty to do those things. And at that time, it was obvious that the director looked at the poster in the wrong way.

The deer farm belongs to his family, and there are many bodies buried in it. He has been painting deer, and he also said that he often heard women's voices, and his family was anxious to sell the deer farm. When he saw Sister Dong's mummy, he said it was here. Ji Zheng's mother and other senior partners killed and buried the body. That high-rise should be the father of the Korean police, developing this place in order to reduce the land price.
