When Song Xichen and the others arrived at the scene, they found that there were already a lot of people inside and outside here, and people were watching in fear and horror. That's human nature, a complex thing. I'm scared but I can't help but look at it.

At this time, Song Xichen followed the eyes of the crowd and looked out of the balcony on the second floor.

A man was hanging there, all red, as if blood was dripping down. It also seems to have something wrapped around his neck.

In order to prevent the adverse effects from continuing to expand, the technical investigators were slowly lowering the body from the second floor after quickly collecting evidence.

After Song Xichen and the others trotted over, it was really another miserable scene. Especially after Miao Lan saw this scene, she happily went to the trash can and vomited.

Song Xichen saw the same disemboweling corpse as Kang Ziyan, and his mood became heavier. This murderer must be the same person, the modus operandi is so similar, and even the details are exactly the same.

This murderer is not only murderous, but also a naked provocation to the police, he actually dares to hang the body here in broad daylight. Song Xichen's mood became even heavier, this murderer was really bold.

They must bring the killers to justice as soon as possible. Otherwise, he was afraid that there would be new tragedies.

Sure enough, the forensic doctor Lao Jia also said: "Except for the different tools of strangulation, the rest are almost the same." Kang Ziyan was strangled with the stockings on his body, while Ma Yingdong was strangled with his belt. The details will be discussed when the autopsy report comes out. ”

After Lao Jia finished speaking, he left with the assistant and the corpse.

Song Xichen left Sun Yuke to help maintain order at the scene, he went up to the second floor alone, Miao Lan was still vomiting there in the dark, she finally begged Captain Song to bring her to the scene, but she didn't expect to encounter this situation as soon as she came here.

Song Xichen walked up the stairs step by step, and before he reached the second floor, a strong smell of blood rushed straight to the door. Some technical investigators were already busy collecting evidence in the room. He stepped into the room, and it was even more miserable. There were bloodstains everywhere, trails of dragging. It seems that Ma Yingdong had a fierce struggle before he died. But when he entered the room, he felt strange, and although the room was covered in blood, not a single piece of furniture was scattered and fell to the floor.

And the bloodstains all over the house, at this time, look like the murderer deliberately left it for the police to see.

Not only is any furniture neatly arranged, but there is no blood on any of the furniture. It seems that the scene was cleaned again this time.

Sure enough, apart from the bloodstains all over the ground, the police found nothing again.

From the time the body was hung out to the time the police arrived, it was only a matter of ten minutes.

But the murderer seems to have disappeared on the spot, and there is no trace of him in any surveillance video, like a drop of water melted into the sea.

Even the nearby residents did not find any suspicious people, which shows that the murderer may have looked very ordinary, just like ordinary people.

So although you and I seem to be ordinary people, maybe the devil is hiding around you and me. He may just be wearing an ordinary coat, but you don't know it, and you even think of him as a good person that you can't meet in a hundred years.

At this time, Liu Yiqiang came to Song Xichen and said to the side: "Boss, there is a new discovery." ”

It was found in the surveillance video of the parking lot that a person wearing a low cap, wearing a mask, wearing black clothes, wrapped so tightly, and walking so fast, must be a suspect.

Song Xichen hurriedly came to the parking lot with Liu Yiqiang, Liu Yiqiang pointed to the monitor on the side and said, "This monitor captured it." "They followed the suspect's walking route, all the way out of the underground parking lot and onto the street. That's when they found a small shop at the exit of the parking lot.

The owner of the store was a chubby aunt, and when she heard that it was a policeman, she was very enthusiastic and cooperative. Quickly turn on the surveillance video and let the police view it. Soon Liu Yiqiang found the suspect, but to their surprise, the suspect actually dismantled all the weapons on the street, took off his hat and clothes, and threw all these things into the trash. Sure enough, Song Xichen found the clothes that were thrown away in the trash cans shown in the surveillance video.

The video shows that the man finally rode away on a small electric motorcycle, and he was wearing a happy errand clothes, and the clothes also had the phone contact information of the happy errands.

Seeing this, Song Xichen already roughly understood in his heart, and it was estimated that it was a trick played by the murderer, but he still let Liu Yiqiang run a happy errand in person. Sure enough, the little brother in the video said: "He received an order to go to the designated garden to open the box, put on clothes, and then go to Fengru Community, walk aside according to the route on the map, and throw the clothes and other clothes on the side of the road and wait for the trash can after walking." ”

Liu Yiqiang knew that their clues were estimated to be broken again, and sure enough, he saw that all the order requirements were remarked in detail in the remarks of the order, and even the route map was directly printed on the computer.

Liu Yiqiang carefully kept all this evidence and truthfully reported it to Song Xichen.

The evidence that Song Xichen has found so far has confirmed that Han Yijing's deduction of the murderer at the scene of Kang Ziyan's crime. The murderer is indeed a cunning criminal with a relatively high IQ and a thorough work.

After coming out of the scene of the crime, Song Xichen and Miao Lan went all the way to the key high school where he once studied. Unexpectedly, they were quite lucky, but the homeroom teacher of their class has not yet retired, but is now the school's dean.

With Song Xichen's particularly respectful voice: "Teacher! ”

Their homeroom teacher was stunned for a moment, then immediately reacted and said suspiciously: "Song Xichen?!" ”

Song Xichen nodded and said, "Teacher, after so many years, you still remember me." ”

The head teacher smiled and said, "Of course I remember, you are the one who said in front of the teacher that when you marry that girl in the future, you will send me joy candy." How could I forget. I've always remembered it all these years. You won't forget, will you? ”

Song Xichen scratched his ears like a child who made a mistake, and quickly replied: "No, I always remember it." ”

In fact, he has long forgotten these glorious deeds.

The head teacher then asked, "I heard that you are now a police officer?" I didn't see you at the class reunion later. ”

Song Xichen suddenly thought of the task of this trip, and hurriedly said, "Teacher, in fact, I came this time to learn something from you. Do you remember that there was a girl named Kang Ziyan who was in the same class as me at the time? ”

When the head teacher saw him mention this girl, her face changed significantly, and she nodded slowly and said, "I remember." And a year or two ago, when the class was at the meeting, I seemed to remember that she was still here, and she introduced her as a painter now. ”

Song Xichen then asked: "Then do you remember, what is the relationship between her and Ma Yingdong, who is in a class one grade higher than us?" ”

The head teacher pondered for a moment, then said, "I don't know what their relationship is, but I dealt with one thing at the time. At that time, a few of them teamed up at school to bully a student who was one year below you. ”

Song Xichen said: "I didn't hear it at that time. ”

The head teacher said: "After the school dealt with this matter, it strictly banned the spread of this matter. ”

Song Xichen felt that he was about to touch the corner of this serial murder case, and he asked, "Who else bullied that girl at that time?" ”

The head teacher thought for a while and said, "It's been too long, I only remember that a person in our class named Li Xiaoyu also participated, and I don't know the rest." ”

Song Xichen hurriedly asked, "What's that girl's name?" ”

The head teacher paused for a moment and said, "It seems to be called Jin Yaxuan." ”
