Han Bin nodded, and agreed with Liao Pingsi's suggestion, this proposal was decent, not new, and Han Bin didn't have much hope.

"What do you think of the Z mark on the neck of the deceased?"

Wang Xiao said, "I have seen a foreign movie called Zorro, which tells the story of the middle of the 16th century, when the warlords and bureaucrats were entrenched, and the people were struggling to make a living, and the masked righteous hero Zorro worked hard to eradicate the bullies with an elusive attitude.

This Zorro has a trait, he likes to leave the Z mark on the bad guys, which is very similar to the situation on the victim.

In addition, the foreign name of the movie Zorro is Zorro, which means fox in the Spanish language. And the nature of the fox represents cunning.

I guess the killer left this mark on the victim, whether he was paying homage or imitating Zorro. ”

Han Bin stood up and wrote a Z on the whiteboard, "I also watched the movie Zorro when I was a child, and it is a word in my country to describe it as doing the right thing for heaven." The murderer felt that Zhang Haonan was a bad person, so he tried and punished him in his own way.

This is in line with the way the victim died, as the victim was controlled by the killer before he was killed, and it was easy for the murderer to kill him, either by stabbing him in the throat with a sharp blade or by strangling him with a rope.

But instead of choosing these simple killings, the killer chose a more complex and ritualistic way, smoking the victim to death with a cigarette. Although cigarettes are not good for health, they are not toxic in themselves, and most people in China smoke, and one cigarette or even a few cigarettes are not enough to affect people's safety.

In order to be able to kill the victim, the murderer made him smoke dozens or even hundreds of cigarettes, which greatly increased the difficulty of committing the crime and the risk of exposure. From this point of view, the murderer's sense of ritual is very heavy, and there is indeed a way to do the right thing for heaven.

But then again, although the victim smokes in the elevator, although it is immoral, it is not the most vicious, and the murderer's punishment is somewhat excessive, and if the conviction is based on this standard, many people will become the target of the murderer. ”

Han Bin took a sip of tea, moistened his throat, and continued, "There is another possibility, the murderer did not really want to do the right thing for heaven, but to cover up the real purpose of the killing, Zorro was just a cover he was looking for, just to interfere with the direction of the police investigation." ”

After Han Bin finished speaking, Wang Xiao echoed, "The Han team's analysis is very comprehensive, and I also think that we should start from the victim's surrounding relationship, there is no hatred in the world for no reason, let alone killing for no reason, there must be some reason that led to this homicide."

Judging by the available evidence, it is likely that smoke was the direct cause of the homicide. Of course, it may also be like the analysis of the Korean team, this is just a cover. ”

Han Bin looked at Zu Dawei in the back row, "Zu Dawei, you used to work in the Criminal Investigation Brigade of the Chengnan Branch, and in the summer of 2018, there was a homicide case in the Chengnan District, and there was a Z-shaped sign on the right side of the deceased's neck, do you have any impression?"

Zu Dawei replied, "Yes, I also participated in the investigation of this case back then, but unfortunately because of the lack of key clues and evidence, the case has remained unsolved, so I am more impressed." That case was filed on August 21 and was named Case 821. ”

Zu Dawei did not participate in the on-site investigation of the Rongyuan community before, Han Bin gave him a dossier, which has some relevant information, Zu Dawei has already seen it, "The Z pattern on the right side of the neck of the deceased Zhang Haonan is very similar to the deceased in the 821 case that year, and it can even be said that it is exactly the same, but the way of being killed is a little different."

Zu Dawei sighed, "Actually, I don't want to think about this case, the murderer's methods of crime are very cruel, and the victim died a very tragic death, not only me...... Many veteran criminal police officers were shocked when they saw the scene.

The victim died in his home, his tongue cut off, his mouth gagged, and finally suffocated due to blood loss. The victim was in great pain before he died, and his flesh was worn out in order to break free from the rope. ”

Wang Xiao said, "According to your description, the victim should have moved a lot before he died, didn't the neighbors hear the movement?"

"The victim's family is from an urban village, and they dug a cellar in their yard, and the body was found in the cellar, and the victim was a woman, tied to a chair, and by the time the family found her body, it was already two days later, and the body was already smelly. ”

Han Bin asked, "What is the reason for the victim's murder?"

Zu Dawei was silent for a moment, "At that time, there were two theories, this victim was a little older, and the people from the same village got together, and they liked to say that some parents were short. A girl in the same village, who was still in high school at the time, was pregnant, and raised her body at home after the abortion.

This is not a glorious thing, the girl's family has been hiding it, but they don't know where the victim got the news, so it spread in the village.

When the girl heard this, she felt shameless, and she didn't dare to go out of the house. The parents and relatives at home also couldn't raise their heads, and this matter was a lot of movement in the village.

Later, the girl jumped from the three-story building of the family without carrying it, and the person was not in danger of life, but her leg was lame. Many people in the village said that she had killed the girl.

Not long after, the victim was killed by cutting out his tongue. The right side of the neck is cut out with a Z pattern. ”

Zu Dawei paused for a moment and organized his language, "Another theory is that the deceased was killed for other reasons, and the reason why the murderer killed the deceased in this way was to cover up the real reason. ”

Han Bin asked, "This case has not been solved for a long time, why has it not been handed over to the city bureau?"

Zu Dawei hesitated, "The situation of the case was a bit complicated back then, we caught a target with major suspicions, and we always wanted to find enough evidence to convict him, and the hope of solving the case was relatively great at that time, and the leaders of the sub-bureau felt that they had the ability to solve the 821 case."

The result of the investigation backfired, the evidence was found, but it was not the evidence of the conviction, but the innocence of the suspect. At that time, the investigation also reached a dead end, and at this time, a long time had passed since the time of the crime, and many clues to the case had been broken. ”

Han Bin listened very carefully, and after Zu Dawei finished speaking, he glanced at everyone, "What do you think of the 821 case and the case of Rongyuan Community?"

Liao Pingsi said, "The two cases seem to be committed in different ways, but in essence, they are both punishing the victim, and the victim of the 821 case likes to chew the root of his tongue, so his tongue is cut." The victim of the case in the Rongyuan community liked to smoke in public, so he was smoked to death. To borrow a phrase from Master Jin Yong, it is all 'to treat others in their own way'. ”

Zhao Ming on the side said, "The connection between these two cases reminds me of a movie called 'Seven Deadly Sins', I don't know if you have seen it?"
