A cleaner fished out a strange bag from the fountain pool, and according to his experience for more than ten years, a heavy bag like this usually hides a surprising treasure.

Unexpectedly, as soon as he untied the bag, he smelled a strong stench, and the man endured the smell and stretched out his head to look at it, and the next second he was so frightened that he collapsed directly on the ground. It turned out that the bag was actually a broken female corpse.

After receiving the report, the police quickly cordoned off the scene, and after a careful search of the neighborhood, the officers fished out a total of three large black bags in the water. More than 20 body parts, large and small, were found in these bags, but what made the police even more angry was that the forensic doctor found a fetus that had formed in the abdomen of the deceased.

This is the fifth case of a pregnant woman's body mutilation in a month, but unlike the previous four, the body parts found at the scene this time were not only deliberately frozen, but also the location of the body has also changed significantly.

An in-depth autopsy by the medical examiner found that the body parts were covered with blow wounds, and even some of the internal organs showed signs of internal bleeding.

Strangely, the flap at the break of the lower limb body appears messy, while the cut of the upper limb appears neat. Given that no trace of anesthesia was detected in the body, the forensic doctor guessed that the murderer should have dismembered the deceased alive from the bottom up.

The fetus in the abdominal cavity is almost eight months old, and the child in the mother's body during this period can already hear the voice of the outside world, so the police suspect that the murderer is a person with an extremely twisted heart.

Out of the forensic office, the police had already investigated the identity of the deceased, the woman's name was Zhang Yi, 28 years old, an accountant of a trading company. Her husband has been away on business for many years and is now on his way back.

Just as the police were waiting for the deceased's husband to come back to investigate social relations, Xiao He suddenly received a call from the detention center.

The other party said that if he didn't want the next victim to appear, he would ask Xiao He to immediately go to the detention center with the case file to find him. In order to solve the case as soon as possible, Xiao He came to see this mysterious person suspiciously.

After reading the information of the five victims, Jiang Yaodong directly told him that from the change in the location of the body dumping and the modus operandi, the murderer of Zhang Yi was not the same person as the serial murderers in the previous four cases.

Because the forensic doctor found anesthetics in the bodies of the victims in the first four cases, which shows that the murderer only dismembered the body for the convenience of throwing the body, but the murderer in the fifth case was completely different.

In view of the blows and fractures on the deceased's body, the purpose of the crime was simply to enjoy the satisfaction of the killing.

Jiang Yaodong also specially instructed Xiao He that the murderer chose the place where the body was dumped in the central square, which just shows that he was trying to win attention and imitate the crime.

The first time such a murderer imitates a crime, the target and the place of dismemberment are generally in his own psychological safety zone, and the deceased will definitely be tracked and observed in advance, so he contacts the police to find suspicious people from the deceased's life trajectory.

After hearing this, Xiao He thought that he could not conclude that the murderer was not the same person based on these changes alone, and he did not continue to waste time on Jiang Yaodong, and left the detention center directly.

After returning to the police station, the officers screened the surveillance near the deceased's community, and sure enough, they found a man with a peaked cap who had followed the deceased more than once.

And the last place where Zhang Yi appeared was next to the garbage heap at the back door of the community, she seemed to be talking on the phone at that time, although she felt the movement behind her, but she didn't seem to notice the man who followed her.

Immediately after Zhang Yi walked out of the surveillance screen, he never appeared in other surveillance again.

Therefore, the police speculated that the man in the hat who followed her may be the murderer of the serial murder case. However, because the man's appearance could not be seen clearly, the police could not lock the person's identity for the time being.

The police officer in charge of technical analysis made an unexpected discovery in the deceased's mobile phone, he scanned the software in Zhang Yi's mobile phone one by one, and accidentally detected a mysterious software disguised as retouching.

After entering this software, I found that this is actually a very large-scale chat T room, and the condition for entering this chat T room is that you must upload a video of yourself.

The administrator will assign the user's level according to the video scale, and the higher the level, the more videos can be watched. And Zhang Yi chatted frequently with an account called Evil Man in this chat T room.

The content of their chat is also very direct, and there is a dialogue in which Zhang Yi hopes that the evil man can arrest her on the road.

In this way, the man who followed her is likely to be this evil man. In order to lure out the person, the police used virtual information to register an account on the site.

and visited the villain's homepage many times, which attracted his attention, and sure enough, within two hours, this person began to take the initiative to talk to the police.

In order to lure him into the bait, the police pretended to be pregnant and turned on the video with the other party, but the evil man looked cautious, and except for a pair of eyes, everything else was tightly covered.

It can be seen from the look in his eyes that he seems to be very satisfied with the police officer, and he quickly can't wait to send the meeting address.

Seeing that the fish had been baited, the police officers disguised themselves and went to a wholesale market in the old city according to the address, and other police officers also wore civilian clothes and lurked as vendors in the surrounding area.

But the other party seemed to be prepared in advance, he asked the police to go to the designated location first, replaced his mobile phone with an old-fashioned mobile phone that could not be tracked, and then constantly changed the route to let the police turn into a deserted building. Unexpectedly, as soon as he came in, he was stunned by the man in black behind him.
