super brain event book

If Li Yuanyuan grabbed something that could prove the murderer's identity at the last moment of her life, and the murderer couldn't take it away from her hand in a simple way, then amputating her fingers with a chainsaw is the most effective way .However, this seemingly reasonable speculation was refuted by the senior.

"I don't think Li Yuanyuan was holding anything in her hand."

As expected, the senior received Hezi's puzzled look.Looking down for a while, he decided to explain this question to Hezi from the basic definition.Since Hezi was able to conjecture that the murderer could not open Li Yuanyuan's clenched hand through ordinary methods, it proved that Hezi at least knew some information about the rigor.In order not to disturb the cute junior, the senior cleared his throat and put on an appearance that he was going to give a speech.

"After death, the muscle tension disappears, the muscles become soft, and the mandibular joints and limbs can move freely, which is called muscle relaxation. Afterwards, each muscle group gradually stiffens and fixes the joints, which is called rigor rigor, which can make the corpse appear rigid. Hezi, the situation you are assuming is the situation where rigor mortis has already formed. Due to the formation of rigor, the murderer could not open Li Yuanyuan's tightly clenched hand with his own strength, so he had to use a chainsaw to cut his fingers."

Deeply interested in the senior's popular science, Hezi nodded repeatedly, admiration flowing from his bright eyebrows.Originally, I only knew that the senior likes to collect all kinds of weird data, but I didn't expect him to know the knowledge of forensic science.With the excitement of wanting to show off his senior to the world, Kazuko signaled him to continue talking.

"Okay, let me talk about the onset and remission time of rigor rigor. Rigidity generally begins one to three hours after death, first appearing in some small muscle groups; it develops to the whole body in four to six hours, and reaches its peak in twelve to fifteen hours , joint stiffness all over the body; it begins to relieve within 24 to 48 hours, and is completely relieved in three to seven days. Of course, rigor will be affected by many factors, such as temperature and weather, which will cause some time differences."

"So?" Hezi, who was fascinated by listening, has long since ignored his reluctance to be refuted by his senior, and only wants to hear his senior's opinion.Her understanding of rigor is nothing more than a few words mentioned in suspense dramas and mystery novels on the Internet, and it can even be said to be confused.

"So, rigor does not appear immediately after death. Even for small joints like the fingers, it takes a certain amount of time to form rigor. If your guess is true, the murderer did it after killing Li Yuanyuan for a while. The dismemberment of the corpse is equivalent to the fact that the murderer realized that there was evidence in Li Yuanyuan's hand after she died for a while. Thinking about it this way, the time gap that must exist is very strange. Could it be that the murderer decided to divide after a long time after committing the crime? Why did the murderer behave in such an unreasonable way? Don’t forget, it was in Lin Ruocai’s villa. The longer the murderer hesitates and delays the crime, the more dangerous he is.”

Opening her mouth slightly, Hezi suddenly realized, but her sudden realization was not because she approved of the senior's words, but because she found a strong support to perfect her speculation.

"I know why the murderer wants to dismember the body!"

Xiaobai, who was touching the senior with his elbow, signaling the senior to give him the potato chips, hesitated. He took the potato chips from the senior without tearing open the pocket, and turned to hold the bag and look at Kazuko.The senior knew that he didn't understand what Kazuko was thinking, so he pulled the potato chips out of his arms, opened them and handed them back to him.

"Hezi, tell me." The senior opened the mouth for Xiaobai.

"Okay." Confident in his speculation, Hezi explained: "When the murderer attacked Li Yuanyuan, she resisted, and during the confusion, Li Yuanyuan pulled something off the murderer, but the murderer couldn't find it at the time. After killing Li Yuanyuan, the murderer did not intend to dismember the body, but hid the body in the laundry room. After a while, the murderer realized that something was missing from his body, and after recalling it, he realized that it was in Li Yuanyuan's hands In order to destroy the evidence, the murderer decided to take the things back. However, due to the long interval, Li Yuanyuan's body became stiff, and the murderer tried a lot but failed to break her hand. In desperation, the murderer used a chainsaw Li Yuanyuan's fingers were cut off. If other parts of the body were intact, just the fingers were cut off. It is easy for people to guess the reason, and the murderer also knew this. In order to confuse the public, the murderer dismembered the whole body, in order to To cover up the real purpose of cutting off the fingers."

As soon as this conclusion came out, the senior almost applauded.Hezi not only explained the murderer's strange behavior of cutting off his fingers, but also solved the problem of dismembering the corpse together, which can be said to kill two birds with one stone.Just when the senior was going to follow this train of thought to further explore who the murderer was, Xiaobai spoke in a deep voice.

"wrong."

"Huh? What's wrong? I think Kazuko's explanation is very reasonable." The senior grabbed a handful of potato chips from Xiaobai's pocket and chewed them.

"Kazuko's hypothesis cannot explain the phenomenon that the chainsaw is not in the laundry room and the finger is on the first floor."

"It's just that I haven't figured it out yet. It doesn't mean that Hezi's guess is wrong."

"No." Lowering his eyes, the slender eyelashes cast a small shadow under his eyes, blocking the darkness before dawn in his pupils.The prank scenes in the study room of the villa were played back in Xiao Bai's mind, from the blood-soaked walls to the scattered corpses on the ground, and finally fixed on the amputated fingers.The fragments of the incident circled and assembled as if swept by a storm, and finally, everyone returned.The puzzle is complete.

"Xiaobai?" Stretching out his hand and shaking it in front of his eyes, the senior muttered in his heart, why did this child suddenly wander off again.

Looking up at the senior and Hezi, Xiaobai slightly curled the corners of his mouth, the seriousness in his eyes was unusual. "The truth is that all the details can be strung together. If there are any fragments that cannot be pieced together, it will not be the truth. Therefore, I think that Hezi's speculation is incorrect."

Supporting his chin with one hand, the other hand stretched into Xiaobai's arms to grab potato chips. The senior's eyes sparkled, "Xiaobai, you seem to know the truth, don't you?"

"Yes." Xiaobai affirmed.

"Then what are you trying to do, tell me quickly!"

Pausing for a while, Xiaobai sat up straight and stuffed the potato chips into the senior's hand by the way.He met Shang Hezi's eyes, as if he wanted to give her encouragement, but also seemed to remind her of something.

Startled by Xiaobai's eyes, a bad premonition rushed to his brain, Hezi's expression was a little stiff, and he said slowly: "Xiaobai, what is the truth?"

"We always thought that Lin Ruocai had no time to commit crimes, but we were wrong. Lin Ruocai did not have time to dismember the body, but that doesn't mean she didn't have time to kill people."
