Version 1: According to the literal and plot, the murderer should be: camel's mother. According to the plot, Tuozi 12 years ago was only about 35 years old, and none of his wives were abnormal and ate people, especially children and their placentas. Doctors in our country, especially the elderly female doctors who are engaged in delivering babies, will eat these things. Their mothers must be very smart and will dismember their bodies for doctors.

The process should be roughly as follows:

Tuozi's mother and father are gynecologists (also private clinics) and crematorium workers (his father should be extremely dissatisfied with the society at that time). The camel has been exposed to the process of eating people and burning corpses since he was a child. He is psychologically abnormal and ugly, and he can't marry a wife. Parents who love their son want to find a woman to be their son's wife.

Diao happened to be a pen pal at that time, that is, Huang Baicheng, and later the husband of Xia Yuping. Because of an unexpected pregnancy, she went to a small clinic to have an abortion. As a result, she was taken away by Tuozi's mother, imprisoned for about eight days, and threatened Diao as her daughter-in-law with reputation (it was not easy to go to college at that time, and Diao was more interested in these things in the countryside), but she refused. In the process of imprisonment, Tuozi's father became angry and violently attacked Diao. Seeing this scene, Tuozi's mother angrily accused her father, who may have repaired Tuozi's mother, so Tuozi's mother thought that not being with such a woman would affect her later life and threatened to kill Diao Aiqing on the spot. In the evening, Tako's father, who was drinking because of a quarrel, complained in the room again. After seeing Diao, I had a whim and asked him to write down his words. Diao was afraid after listening to his mother during the day, so he took the opportunity to write a note as an opportunity. This note was later hidden in a book by his father for a long time. That's why the police asked the camel why he said, you will regret it!

As for Xia Yuping's chopsticks, she inadvertently saw the correspondence between Diao and Huang Baicheng. Combined with the inference of online users and Huang's treachery, she mistakenly thought that Diao was killed by Huang. She thought that killing Huang was revenge for Diao and herself.

So this explanation is more reasonable, because the original text mentioned that only one murderer committed the crime.

Version 2: The killers are camels and soldiers. "Ten Deaths Two" wrote: Bao decapitated, thought for a while, suddenly looked up and read word by word: camels and troops killed ... There is also a far-away garbage dump near Tangshan, a blue whale, and local people know that there are garrisons in these two places. ...

The author implied that he was a soldier.
