How do monsters and murderers in Korean dramas analyze?

The 20-year serial murder case was finally solved. The seemingly weakest person is actually Jiang Zhenmo, a "monster" full of resentment against the world, and a pervert who buried his daughter alive without mercy.

Jiang Zhenmo's wife left him, which made him have evil thoughts about beautiful women. After killing them, he tied their feet to prevent them from running away. If this is taken as a reverse inference, is it possible that the unknown woman is her biological mother, Jiang Zhenmo's ex-wife, who immigrated illegally after running away from home, was caught by the police, was used by Han to get to know Lee Dong keun and others, and was later discovered and killed by Jiang Zhenmo?

Appreciate:

"When you stare at the abyss, the abyss is staring at you." In the Korean drama Monster, no one is a normal person, but they are all ordinary people with their own emotions. Each of them has more or less unknown secrets.

After the Jiang Minjing case, Wanyang City once again set off waves. Li Dongzhi, once suspected, is also at the forefront, undoubtedly becoming the most powerful candidate for the murderer. After this incident, different classes and camps in Wanyang, which seems to be calm, began to expose their own careful thoughts.

The upper class, mainly Park Jung-jae's mother and Han Zhuyuan's father, began to make peace for their own selfish desires and turned Li Dongzhi into a whipping boy.
