Gu Song is no stranger to Mozi Bridge. In fact, this is not the first time he has been here to survey the site. When he first came to the criminal police team as an intern, he once came to this place with their former captain to deal with a criminal case. It's just that this case was a simple fight and death by negligence, but this time it was a challenging serial murder.

According to the informant, he was a homeless homeless man who had been living under the bridge of Mozi Bridge for some time. Because the place was basically deserted, few people came to disturb him, and no law enforcement officers chased him away, so he used it as a shelter to protect him from the wind and rain.

During the day, he often went to the nearby market to beg, and when it was dark he went back to sleep under the bridge. At about six o'clock this evening, he suddenly felt a headache in the process of begging, so he called it a day early and came back to rest, only to find that an uninvited guest was lying on his ground.

At first, he was a little annoyed, thinking that someone had taken over his nest, but when he got closer to find out what the person was talking about, he found that the person lying on the ground was not a homeless man like him at all, but a corpse with blurred flesh and a terrible appearance.

Forensic Chen conducted a preliminary examination of the deceased and confirmed that his identity was the suspect Dong Wei, who had been looking for by the police for more than a month, that is, Liu Fan, who was born in Sanqiao Village and was suspected of killing Liu Fulai and his wife.

Similar to the "9/16" and "9/29 cases", the victim was also killed by the murderer who pierced the heart with a single-edged knife. In addition to the fatal wound on the left chest, the victim was also stabbed by the murderer frantically forty-seven times all over his body, each of which used a lot of force, as if to vent his extreme dissatisfaction. In addition, the victim's lips were pierced by four steel nails with a length of 50 mm and a diameter of 2.8 mm, and the characteristics of the crime were the same as those of the two previous cases.

The only difference is that the victim had been severely tortured by the killer before his death. If the murderer in this case is the same person as the murderer of Ma Zhichen and Li Baofang - the arrogant and provocative "clownfish killer" of the police, then his purpose is undoubtedly to make the victim confess the crimes he has committed before he dies. To confirm this speculation, it is only necessary to find that iconic trait of the crime.

Sure enough, Forensic Chen found a clownfish about 6 centimeters long in the victim's throat, and whether there were other articles hidden in the clownfish's body needed to be further dissected and confirmed.

It is worth noting that next to the victim's body is a dark blue travel bag, which is extremely similar to the travel bag that appeared in the surveillance video of a hotel in Jinshui County some time ago, and should be owned by the victim. The travel bag contains a few changes of clothes and toiletries, and in addition to a very common black plastic bag. It's just that what was in that plastic bag was not only unusual, but it made people feel creepy.

"It's ......" Xia Shi checked the contents of the travel bag, looked at the contents of the plastic bag in disbelief, and didn't say anything for a while. Although he had thought of this possibility before, when he confirmed it with his own eyes, it was still a little difficult to accept for a while.

"This should be ......" Seeing the scene in front of him, Gu Song smacked his tongue in surprise, paused and said, "This is Sun Mingxiang's skull, right?" This kid really keeps it with him all the time, it's really perverted......"

"Maybe Mr. Huo's inference is correct." Xia Shi came to his senses, remembered Huo Yan's interpretation of the characteristics of the "nail killer", and said with emotion, "Maybe Liu Fan committed those heinous crimes for the sake of this head that has been by his side for many years......"

"So, is this the secret he guards even if he kills? But I still don't understand how all this happened. Gu Song shook his head regretfully, thinking that he would never know the full truth of the "9.16 case" and the "9.29 case".

However, things turned out to be unexpected.

When Dr. Chen was dissecting the clownfish, he accidentally found an SD card wrapped in plastic wrap, and the video content inside answered almost all of their questions.

The video was shot in a dimly lit, featureless empty room. Liu Fan was facing the camera, his body tied to an "interrogation chair". He stared in horror in front of him, as if a vicious beast lurked there, ready to pounce on him and tear him to pieces.

It is not difficult to see from the video that Liu Fan has been tortured by the murderer before, and there are countless scars all over his body. He had a slight reluctance on his face, but he had to confess his crime under the control of fear.

The first is the case that took place in the village of Sanqiao in 2004. As the police speculated, Liu Fan was indeed the murderer of Liu Fulai, but his mother Sun Mingxiang was not killed by him.

On the night of the crime, Liu Fulai had a fierce quarrel with Sun Mingxiang because of alcoholism, and then committed domestic violence against Sun Mingxiang. Liu Fan couldn't bear his father's violence for a long time, and he encountered some troubles at school that day, so he was in a very bad mood, and the accumulated anger was about to erupt. At that time, he was bent on killing Liu Fulai for liberation, and from then on, he and his mother could leave the country and get rid of this hellish life completely.

Taking advantage of Liu Fulai's unpreparedness, Liu Fan stabbed him from behind. The knife did not hit the vital point, Liu Fulai screamed in pain, turned around and glared at Liu Fan viciously. Although Liu Fulai is a cripple, his body is much stronger than that of fifteen-year-old Liu Fan. He didn't give Liu Fan a chance to stab him a second time, and subdued him in two strokes, and in an instant, he changed from the person who was almost killed to the one who wanted to kill.

For a few seconds, Liu Fan's heart was cold, he thought that he would die from this domestic violence, and thought that the so-called relief turned out to be that he left this world first. He didn't expect that his mother, who had always been cowardly, would be desperate to scuffle with Liu Fulai in order to protect him.

"Little sail, run!" These were the last words his mother said to him.

He was afraid, scared, and his whole body trembled uncontrollably. He wanted to escape, but he couldn't. An inexplicable courage drives him to pick up the fruit knife that has fallen on the ground, and he must help his mother out of the predicament, otherwise the consequences will be unimaginable.

However, fate is sometimes so cruel and unforgiving. He didn't have time to save his mother, but watched his mother being pushed down by Liu Fulai, her head hitting the sharp corner of the bed impartially, and she died on the spot.

Looking at his mother's eyes full of despair and unwillingness, Liu Fan's emotions suddenly went out of control. He roared and rushed towards Liu Fulai, and the knife stabbed into Liu Fulai's body again and again. He didn't know how long his madness had lasted, and when he came back to his senses, Liu Fulai was already in a pool of blood, and the room was filled with a strong smell of blood.

It's over, it's all over. Liu Fan sat on the ground dejectedly, looking at the ugly and twisted corpse in front of him, his stomach churned for a while and then he vomited heartbreakingly.

After vomiting, he suddenly felt a lot more relaxed. The fear disappeared without a trace, and was replaced by an irrepressible excitement. He laughed mechanically a few times, then laughed heartily, and finally burst into a burst of hysterical laughter.

A fifteen-year-old boy is facing the corpse of his parents who are still alive, what a strange picture, but Liu Fan doesn't think he is crazy. In his opinion, Liu Fulai's death was deserved, and his mother ......

He looked at his mother's corpse sadly, thinking that this might not necessarily be a bad outcome. At least her mother no longer has to endure Liu Fulai's domestic violence every day and live in fear, which may be a relief for her.
