Investigating the surveillance video of the community, we did not find any useful clues, let alone the trace of the murderer.

I'm used to this kind of ending, after all, the cases that can be solved through surveillance video will not be handed over to our serious crime team.

Soon, I received a list of people who attended the class reunion from my colleagues in the criminal police team, which was a junior high school reunion, and there were 28 people who came to the reunion, including eight women, all students, and no teachers.

Du Qin is one of them.

Lin Zifan, Jiang Tingbai, and Xue Hang were taking the criminal police of the criminal police team to investigate the twenty-eight people who participated in the class reunion at this time, and I believe that there will be clues soon.

After Li Meng and I investigated the surveillance video to no avail, we just returned to the Ningzhou Municipal Public Security Bureau and handed over the surveillance video to the technical department, asking them to continue investigating the surveillance video to see if they could find some new clues.

At this moment, Xue Hang suddenly called me.

The murder happened again......

This time, the scene of the crime was in the building area in the west of Ningzhou City, and Li Meng and I rushed to the scene of the crime immediately after receiving the news.

If this was an ordinary criminal case, he would never have notified me in the first place, and since he notified me, it means that this case has some unexpected connection with the murder of Du Tan that we are investigating.

When we arrived at the scene of the crime, Xue Hang was leading the members of the criminal police team to carefully investigate the scene. A long cordon has been set up at the scene, surrounded by a crowd of onlookers, and the police responsible for maintaining order at the scene are preventing onlookers from taking pictures with their mobile phones.

"What's the situation?" Li Meng and I squeezed into the crowd and saw Xue Hang, who was meditating on the spot.

After Xue Hang saw us, he held the cordon high with his hand and let us in, and before he could speak, he couldn't help but shiver.

The thing that can make him shiver must be extraordinary.

"A man, standing downstairs, was hit in the head by a rooftop wall that fell from a height and was killed on the spot. The skulls were all smashed open, they were all smashed and contracted, and the brains flowed out......" Xue Hang said without further talking.

He said the word "all" three times in a row, which shows that the situation at the scene shocked him.

Speaking of this kind of death, just listening to it made us feel very bloody and terrifying, not to mention that Xue Hang saw it with his own eyes.

"In autumn, the wind is strong, and the rooftop wall is in disrepair and suddenly falls off, and this matter can be handed over to the criminal police team for investigation, how can you notify us?" I paused and asked him suddenly.

Xue Hang swallowed a mouthful of saliva and said to me, "Because the deceased is also a member of Du Tan's classmates association." ”

"What?!" I frowned and let out a cry of surprise.

"In other words, this deceased and Du Tan were junior high school classmates, and they both attended the class reunion together the day before yesterday?!" Li Meng was also a little surprised, and then asked carefully.

Xue Hang nodded, turned around and led us towards the place of the deceased.

He said to us as he walked: "The deceased's name is Xu Kuan, male, 26 years old, selling mobile phones in a mobile phone store. We checked his belongings and found his ID card and a brand-new, unopened phone in his backpack, so we speculated that he was here to deliver it to the buyer. The specific identity of the buyer, colleagues of the Technical Investigation Division have already begun to investigate, and the forensic doctor is currently investigating the scene. ”

"Old Ren, it's you again." I walked to the forensic doctor and found out that this forensic doctor was my old buddy Ren Qiushi.

I thought he would be busy working on Du Tan's time, but I didn't expect the forensic department to let him come to this autopsy.

Ren Qiushi was squatting on the ground for an autopsy, and after hearing my voice, he turned his head and glanced at me with disdain, and said helplessly: "There are three forensic doctors in our city bureau, but I feel as if I am the only one." As long as I encounter a case in the serious crime team, it is like a division of labor, and it is automatically assigned to me, who else can I be? ”

"Where's your beautiful partner?" I crouched down beside him and asked him curtly.

"You said Zeng Lan, she is in the forensic department to compare and confirm the murder weapon through Du Tan's red and swollen throat cover." Ren Qiushi said lightly.

The autopsy has come to an end and the body has been placed in a body bag to be taken back to the Forensic Medical Department for further autopsy.

"Has the cause of death been clarified?" I asked Ren Qiushi seriously.

Ren Qiushi neatly put all the tools for the autopsy back into the forensic autopsy toolbox and said to me, "Have you seen that big stone?" ”

As he spoke, he suddenly pointed with his hand, and not far from the deceased's body, there was a solid cement brick more than 20 centimeters square, with large pieces of cement wall skin hanging on it, and there were several broken brick slags on the ground.

The large cement bricks were stained with blood, and it seemed that the culprit was responsible for the accident.

"Such a large solid cement brick, at least more than 20 kilograms, smashed heavily on people's heads from the height of the sixth floor......" Ren Qiushi stopped abruptly after saying half of his words.

For it is needless to say that you will surely die.

Once again, I set my eyes on the solid cement brick, and I couldn't help but feel my scalp tingle and feel a pang of fear.

"The deceased's head was smashed, the spine was severely dislocated, and the central nervous system was broken, either of which alone could be an absolutely fatal injury, resulting in death." Ren Qiushi stood up, took a deep breath, slowly closed his eyes, and calmed down.

This kind of death is really miserable......

"Was it an accidental death?" I asked him suddenly.

Ren Qiushi slowly opened his eyes and said to me seriously: "Judging from the current situation, this is the case. This solid cement brick is the enclosure of the roof of the building. Autumn is windy, coupled with disrepair, cement bricks fall off...... This man is too unlucky. ”

After he finished speaking, he paused, and added: "Judging from the situation at the scene and the corpse, it is indeed an accidental death, but I have to go back for further autopsy work to see if there is any suspicion about the cause of death, isn't the cause of Du Tan's death also a seemingly accidental?" In the end, the suspicion was found. ”

Ren Qiushi was right, although the cause of Xu Kuan's death was a wall falling from a height, after the criminal police team confirmed the identity of the deceased, they found that Xu Kuan and Du Qin were junior high school classmates, and they both participated in the classmate opportunity at the front desk.

The death of the two people in quick succession makes me feel a little suspicious, if it is really an accident, it is too coincidental......

Originally, the criminal police team also characterized Du Tan's death as an accidental death, and this time Xu Kuan's death was an obvious accident, but was it really an accident......
