Through the fingerprints and footprints of Guo Jialu's family that we collected, Jiang Tingbai compared them with the footprints of the eighth person found by the technical team at the scene of the crime.

In the end, Jiang Tingbai found that Guo Jialu's footprints and the footprints left at the crime scene were both 36 yards, and the foot shape was the same as the footprints found at the crime scene.

At the same time, according to the results of the trace examination and comparison of footprints, as well as the inference of the height and weight of the footprints of the eighth person found at the crime scene, it was found that the height and weight of Guo Jialu and the eighth person at the crime scene were also highly consistent.

In the office of the Serious Crime Team, the five of us sat together again to conduct a new round of case analysis and discussion based on the current 36-yard footprint.

"Judging from the clues and results obtained so far, Guo Jialu is suspected of committing a major crime!" I said in earnest, and this meeting was the beginning of this discussion on the analysis of the facts.

Li Meng spoke first, and she said in a deep voice: "If Guo Jialu is the murderer in this case, then how did an eleven-year-old child complete such a thorough murder case?" And in the entire process of committing the crime, Guo Jialu killed seven people in a row, and the methods were extremely cruel and clean. Especially after encountering Qin Jing's resistance in the kitchen, he was even more unhurried and responded calmly. ”

Li Meng's doubts are not unreasonable, but in the final analysis, she still feels that Guo Jialu is extremely inconsistent with the criminal profile she made and the image of the murderer in her mind.

Lin Zifan nodded, and agreed with Li Meng's opinion on this case, he said quietly: "Guo Jialu and Shan Jinfeng do have a grudge, and both of them have also said to each other that they want to kill each other's whole family, but this is a child's unscrupulous talk after all. And can the thinking of an eleven-year-old child really raise the hatred between classmates to the level of killing people? ”

After Lin Zifan finished speaking, Xue Hang immediately picked up the conversation and added: "The murderer didn't even let go of the three-year-old Shan Jinping, an eleven-year-old child, does he really have such a vicious heart?" It's really horrible. ”

In the first round of speeches, everyone expressed their disbelief in Guo Jialu's proposal that he was the murderer, and they also gave their different views.

They analyzed the facts of the case from different angles.

However, the 36-yard footprint is irrefutable evidence.

Guo Jialu's height and weight are similar to the height of the eighth person at the scene of the crime, which is also ironclad evidence.

But even then, there is another possibility.

That is, Guo Jialu happens to have almost the same body shape as the murderer.

The reason for our case analysis and discussion this time is precisely to rule out this possibility.

At this time, Jiang Tingbai Youyou, who had not spoken, opened his mouth and said to us: "Don't set your own mindset, don't subjectively clear his suspicion because Guo Jialu is only eleven years old this year. In criminal cases, especially in major homicides, age is not a big deal. age, only in the corresponding liability clause of the law, useful. ”

Jiang Tingbai's words made all of us fall into deep thought.

He is right, we all analyzed this murder case because of the immaturity of the mind of an eleven-year-old child, and our subjective impression of an eleven-year-old child.

"Maybe Guo Jialu was instructed by someone? In many criminal cases at home and abroad, there are cases where children are brainwashed and instructed to complete major homicide cases. I made up my mind and suddenly spoke.

An eleven-year-old child is not yet fully mature, and perhaps he will not do anything illegal or criminal subjectively. But if someone deliberately brainwashes him and makes his immature mind accept some wrong thoughts, it will indeed lead him to the road of breaking the law and committing crimes.

There are many examples of this, especially in war, where some child soldiers, with a childlike smile on their faces, will immediately take out a bomb or *** gun from their pockets and attack you as soon as you turn your back to him.

The Vietnam War is one of the most typical examples, and many American soldiers were treated with severe post-war traumatic stress disorder.

But if you think about it along this line, there are many problems.

"If Guo Jialu is really behind the murder and destruction, someone really instigated it, then this person must have a deep hatred with the Shan family, who is this person? How did he make a feud with the Shan family? Lin Zifan said in a deep voice.

"It's very likely that they have a hatred at work, but for this problem, the criminal police team has already investigated their social connections at work, and when they come back, there will be results." I nodded and explained.

At this time, Xue Hang gave his different opinion: "The key point in this case is, why did the murderer choose to instruct an eleven-year-old child to complete the murder? Isn't he afraid that this eleven-year-old child will have some accidents in the process of committing the crime? For example, being discovered, being countered by others, and being killed by others, thus exposing your identity?! ”

"And, why would this eleven-year-old boy listen to the murderer?" Li Meng followed Xue Hang's train of thought and added another sentence.

This question is also very crucial.

"Therefore, it is very likely that the real culprit behind the scenes is Guo Jialu's relatives, because only in this way can Guo Jialu completely obey the other party's words." Lin Zifan pondered for a moment and suddenly said.

After he finished speaking, he paused, and then said, "Or...... It is likely that the killer was also someone else with 36-yard feet...... Remember the Halloween murder we solved earlier? The murderer was a dwarfistic patient. ”

"But after our investigation, Guo Jialu's relatives did not have dwarfism, let alone adults in size 36, and Guo Jialu's mother was in size 38." I shook my head and said something in a deep voice.

"But a 36-yard foot is too small for an adult, especially for a man. Even if the real murderer behind the scenes is Guo Jialu's father Guo Haoda, Guo Haoda chose to kill people in order to avenge his son. So how did he commit the crime in size 36 shoes? Lin Zifan said as he spoke, his brows suddenly furrowed, and this problem seemed to be stuck in a dead circle.

"So, the murderer is actually a man with 36 yard feet!" Li Meng said suddenly.

Because of her criminal profile, the murderer is a man with 36-yard feet and between the ages of fifteen and twenty.

However, based on her criminal profile, we really didn't find the right person.

Perhaps, we haven't found the murderer yet, so we ignored something......
