In the Forensic Department of the Ningzhou Public Security Bureau, Ren Qiushi had just finished the autopsy.

I walked into the dissection room, and he handed me the autopsy report.

It reads: The deceased suffered a fracture of the mandible, and the skull was fractured due to an embedded fracture caused by the protrusion of the lower jaw, resulting in a fracture of the base of the skull...... The deceased had obvious cerebral percussion contusion, cerebral percussion contusion...... Cervical spine fracture, carpal fracture, elbow joint fracture due to force conduction resulting in ulna-radius and humerus fractures......

Because of the cushioning of the body's soft tissues, there was no severe bleeding in the internal organs, but the inversion of the ribs punctured the lungs, resulting in a closed pneumothorax......

No alcohol, drugs, or hallucinogens were detected in the deceased's body, and the trauma was consistent with a suicide fall.

"I have broken bones all over my body!" I looked at the autopsy report, which was full of broken bones.

Ren Qiushi walked up to me, pointed to the autopsy report, and explained to me in detail: "The deceased has signs of fractures all over his body, from head to toe, the lower the lower the fracture is, so the deceased's falling posture is that the upper limbs land first, then the neck and head hit the ground, and then the chest and lower limbs fall to the ground." ”

After he finished speaking, he brought me to the computer desk, and after a brief operation, a modeling animation appeared on the computer screen.

"Judging from the autopsy results, it is consistent with the signs of a six-story fall. This is a one-to-one 3D modeling restoration of the crime scene carried out by the Technical Investigation Division, according to the height and the location of the fall point to carry out a high fall simulation test, after hundreds of simulations, it can be determined that the deceased fell from the building, there was no lateral acceleration caused by lateral force, that is to say, he fell from the building by himself, no one pushed him. After Ren Qiushi finished speaking, he played me a high-fall simulation test animation.

"Jumped off a building after a phone call? It's impossible to think about it. "I looked at the autopsy report in my hand, my brow furrowed, and I couldn't figure it out.

What did he hear on the phone that he had to jump off the building?

Even if the content of the phone call scared him, then he would be frightened and instinctively avoid seeking protection, how could he jump off the building?

Although there is a theoretical possibility of a misstep and a fall, I absolutely do not believe that it was an accident. The other party called him as Liu Yuzhou, who had died, and they both mentioned "retribution".

What exactly is this retribution?

In the evening, in the office of the serious crime team, everyone held a case analysis meeting as usual, but in these two cases, we have very few clues.

"I carefully compared the fingerprints, footprints, DNA and other biological samples of the two deceased in the two cases with the cases in the past two decades, and found no matching cases." Lin Zifan rubbed his eyes, he had been sitting in front of the computer for seven hours and comparing carefully, very tired.

"Are you sure there's nothing missing?" I asked him.

Lin Zifan waved his hand listlessly: "All cases are synchronized on the network, as long as the information of the two deceased is entered, it can be compared, from the homicide case to the fight, no information about the two was found, they have no criminal record." ”

"No criminal record? So what retribution are they afraid of? Li Meng was very puzzled.

"Killing pays for life, since this retribution took the lives of the two of them, it just shows that the 'bad deeds' they did before were extremely bad." I muttered.

"Is it possible to pick up a murder case without going through the police? Rather, it was reconciled privately? In an era when the concept of law is weak, this kind of thing is very likely to happen. Xue Hang said in a deep voice.

"That being said, I always felt that things were not that simple. Liu Yuzhou and Li Xiaojie's life experiences are extremely similar, and even overlap somewhat, and the bad things they did must be related to their opening of a studio. I said lightly.

Li Meng continued to think along my train of thought, and suddenly said: "Maybe it is unfair business competition, the shopping mall is like a battlefield, although there is no blood, but it is also very cruel. Maybe they annexed their peers by some means, so that the other party's family was ruined and his wife was separated, and then his descendants gathered strength to take revenge twenty years later! ”

"Although your analysis is very reasonable, after all, it is all speculation, there is no evidence, and the police are not writing novels and making movies, how can it be so mysterious, what hatred can be endured for 20 years, and 20 years has already been wrong." I smiled and said lightly.

Li Meng looked at us and explained seriously: "What does it matter, art comes from life and is higher than life, and this kind of thing is not impossible to happen in reality. Besides, as the old saying goes, it is not too late for a gentleman to take revenge, and some hatred, let alone twenty years, even if two hundred years have passed, there will be descendants to take revenge. ”

"Are you talking about the hatred of killing your father and the hatred of taking your wife? Isn't this the plot of a martial arts novel! Jiang Tingbai smiled and quipped.

"I still think this matter has something to do with the fact that they worked together to develop software 20 years ago, because Liu Yuzhou and Li Xiaojie are both team members, and if they can find other members, they will definitely find something." After I expressed what I thought, I said solemnly: "Since it is a case analysis, it is speculation based on the current clues, and our next case investigation direction should focus on the software development team of the year." ”

"How do you investigate what happened twenty years ago?" Jiang Tingbai shrugged his shoulders, very worried.

"Since Liu Yuzhou and Li Xiaojie started the investigation, I don't believe that for 20 years they will not say a word about the events of that year, even if they don't talk about it to their families, they will definitely keep in touch with their team members. Isn't that the case between the two of them, after the team disbanded, they each opened their own private studios, and although they were two jobs, they still worked together. "I spoke my mind.

Li dreamed for a while, and suddenly asked me, "But how can we determine how many members of their team there are?" What if it was just the two of them? ”

After she finished speaking, she added: "Two people can also be called a team." ”

I smiled and explained, "Their team is doing software development, so software development should be divided into at least three categories: data, programs, and art. So, there must be more than just the two of them in this team, there must be more people. And I believe that the reason for the dissolution of their team must also be related to this 'retribution'. ”

Lin Zifan understood what I meant, stretched his waist widely, and sighed loudly: "Hey! It's another big project! ”

"What's the big deal?" Li Meng asked.

Lin Zifan was about to speak, and Xue Hang beside him said quietly: "What Team Qin means is to investigate the social relations of Liu Yuzhou and Li Xiaojie, and it is a carpet investigation, as long as the two know each other, even if they only say a word, they must investigate." ”

I took a deep breath: "This is a helpless move, because such a large-scale investigation will definitely startle the snake, and the murderer is likely to be within the scope of our investigation, so we must lock up the murderer before he finds out!" ”

After speaking, I looked at the night outside the window and said, "We must be in front of the murderer......"
