Profiler 4: Criminal Investigation Team

Qi Shuai panicked when he flipped over, "I, I know Wei Juan, and sometimes we go out to eat and chat together. But Comrade Police Officer, you didn't ask me before!"

Hou Xiyong said: "You used to get close to us all the time. Did you just want to know about Wei Juan's case and feel guilty? Tell me honestly, what is your relationship with Wei Juan?"

"not me……"

Qi Shuai said anxiously: "We are good friends, she died suddenly, I also want to know what happened, but I am married, and she also has a husband. It is not convenient for me to ask, so I just want to ask you from the side."

Hou Xiyong curled his lips: "My friends eat together all day? How did you know each other?"

Qi Shuai licked his lips and said: "Wei Juan came to the company to apply for insurance, and Manager Fan asked me to serve her. I saw that she was quite capable, so I helped her analyze the pros and cons of insurance, and talked about financial management. We got to know each other once and twice. My wife is out of town, and her husband is also very busy. Sometimes we just go out for a meal together. It’s really just eating, shopping, and nothing else.”

This statement may be mostly true, but one point is obviously false.Jiao Yang said calmly: "The day Wei Juan had an accident, were you with her?"

Qi Shuai shook his head and said, "No, it was Saturday, right? We work in insurance, and Saturday and Sunday are the busiest."

"Who is this person then?"

Jiao Yang took out two other screenshots from the surveillance video of the park on the day of the crime, put them in front of him and said, "Do you know each other?"

Qi Shuai was stunned for a moment, and said repeatedly: "I, I made a mistake, comrade police officer, I will explain it all! That day Wei Juan said that she would go home to give some things, and she wanted to practice getting out of the car, so that the I went with her. I picked her up near her home, took her to her parents' home first, put down her things, and we went to a park near her home, where I practiced electric cars with her.

She was riding well, when a pair of students passed by, the boy and the girl.The girl was in the back seat, and she did a Titanic action.Wei Juan said, then let's have one too.I said I would take her with me, but she didn't want to, she insisted on taking me by bike.

But as soon as we went up, the bridge shook violently, and Wei Juan panicked a little. As soon as a dozen electric cars hit the bridge railing, the rope broke.The two of us fell into the water together with the car. I stood up and tried to pull her, but he was pinned down by the electric car and couldn't move. She called for help, and I heard someone coming from the side.

I'm afraid that our relationship can't be explained clearly. If my lover finds out, I have to get a divorce!As soon as I was afraid, I ran to the shore in a hurry.Seeing that the water was not deep, I thought that there were so many people in the park that they would definitely be able to save her, so I left first.Comrade police officer, I really didn't expect that she would drown! "

Jiao Yang came out of the inquiry room and asked Yu Xiaoguang to go through the formalities first and detain Qi Shuai.

Hou Xiyong said: "It's not bad, I really haven't worked in vain these days, at least I can sue him for inaction, or even death due to negligence."

"That's what he said."

Jiao Yang said: "Whether it was an accident or not, it's hard to say now. Let's go, let's go see Director Ji again."

When Ji Yunfan came out of the office, he saw Jiao Yang and the others standing in the hallway, he adjusted his glasses and asked, "What advice does Team Jiao have?"

"No way."

Jiao Yang said: "There are still some details about this case, and I want to ask Director Ji for advice."

Ji Yunfan went to the office behind Jiao Yang and the others, took out the file, opened it, and asked, "Did Team Jiao find anything new here?"

"Indeed."

Jiao Yang said: "We found a related person who was with the deceased that day. Now, can we confirm whether the injury on the forehead of the deceased and the drowning were active injuries or passive injuries?"

Ji Yunfan said: "From the current evidence collection at the scene to the reaction of the corpse, there is no obvious sign that it is a human effect. But this possibility cannot be completely ruled out."

Hou Xiyong was listening behind, and couldn't help grinning, good guy, isn't talking for a long time the same as talking for nothing? !

The scene has been destroyed, but Jiao Yang also looked at the corpse before, only one obvious bump wound on the forehead, the rest, there are no signs of being beaten or scratched.As for the impact injury, Jiao Yang also knows that the impact injury and the blow injury can be distinguished. As for whether she hit it herself or someone else asked her to hit it, it is difficult to say for sure.

But it's difficult, but it doesn't mean it's impossible.

Jiao Yang took a deep breath and said, "I see, Director Ji. I'll do a more detailed simulation experiment again."

This simulation experiment is to find an electric car with basically the same appearance and performance at the same position on the pond bridge in the park, put two mannequins with the same height and weight as Wei Juan and Qi Shuai, and simulate the impact point and impact force. location, to prove that there is no human effect.

The experiment was about to start, when suddenly I saw a girl with long curly hair running and shouting, "Captain Jiao, wait a minute, wait a minute and then do the experiment!"

Seeing that it was the "precious" female intern Ke Luoluo in the team again, Jiao Yang nodded and said, "Xiao Ke, what's the matter?"

Ke Luoluo ran all the way out of breath, rubbed his chest and said: "Jiao, Jiao team, let me go, I am almost the same height and weight as the deceased. Let me do the experiment!"

Jiao Yang paused and said: "This is not acceptable. The deceased died in this environment. The experiment is quite dangerous and cannot be done with real people!"

"Why not?"

Ke Luoluo said: "Only by doing it with a real person can you know the real effect! The dummy can't move, how can you know the real reaction of the deceased at that time?"

Ke Luoluo raised her pretty face and stared at Jiao Yang.

But looking at Ke Luoluo's long curly hair, which is a bit disheveled now, Jiao Yang felt a headache.

Hou Xiyong smiled and gave him a hand, "Jiao Dui, just let someone else take you. These days, how rare are female interns who can escape our criminal investigation. Girls as stupid as Zhou Ying are rare now. , are all giant pandas, national special-level protected animals, we all have to protect them!"

"You also know how to protect yourself."

Jiao Yang frowned and said, "With such a dangerous experiment, who will be responsible if something goes wrong? Are you responsible?"

Hou Xiyong smirked as soon as he heard it and said, "But boss, we also have to protect the work enthusiasm of other young comrades!"

"That's not how work ethic works."

Jiao Yang waved his hand and said, "Okay, let's start the experiment quickly."

Ke Luoluo rolled his big eyes, turned around and jumped on the electric car, grabbed the handlebar tightly and said, "If you don't let me do the experiment, Team Jiao, I won't get off!"

"Cololo,"

Jiao Yang lowered his face and said: "Do you know what kind of team you are in now? The criminal investigation detachment is a secret service. What we are engaged in is the most difficult and dangerous task, shouldering the responsibility of defending the country. The mission of the people is not to let you come to play tricks. You come down to me immediately, this is an order. Otherwise, you will go back to where you came from."

"This is order, right?"

Ke Luoluo pouted, jumped off the electric car, and quietly dodged aside.

In the first experiment, the dummy was placed on the seat, Yu Xiaoguang sat on the back seat, and controlled the electric car to the center of the bridge.

Then he put a sandbag of his own weight, pulled the electric handlebar, and increased his speed to hit the protective rope of the bridge railing.But after bumping it three times, the protective rope didn't break.

Hou Xiyong said: "Head, just look at this point, this incident is not an accident. I said that the rope looks quite thick, so it shouldn't break so easily."

Jiao Yang said: "This rope is newly replaced. The previous rope has been aging for a long time, and there may be accidents..."

"I'll just say it!"

Ke Luoluo said: "Without real experimentation, the effect will not work."

Jiao Yang glanced at her without saying a word, carried out the experiment a few more times, and finally broke the protective rope and successfully fell into the river.

But even after repeated experiments, the forehead of the dummy model could not hit the part where the deceased hit the handlebar.

But Jiao Yang felt that there seemed to be a group of small flames in his heart, which finally ignited.

He returned to the team with a few people, and went directly to Ji Yunfan's office.

"Director Ji."

Jiao Yang handed the experiment record to Ji Yunfan, "Look, can you find a way to prove that the deceased was pushed and hit by someone?"

"Captain Jiao."

Ji Yunfan said unhurriedly: "From a layman's point of view, there is no difference between the deceased being bumped into by himself and being pushed into by someone. In fact, there is a big difference. In an extremely dangerous state, the survival instinct will make the deceased People struggle unconsciously. If someone applies external force at this time, both parties will inevitably leave traces on each other during the struggle. But we have searched everywhere on the dead, but we have not found any traces left by others. DNA. The eyes, ears, mouth, nose, and even the crevices of the 10 fingernails were carefully checked one by one, but nothing was found."

Jiao Yang said: "The deceased must have been flustered at the time of the incident. She may have been knocked out at the first moment and was unable to resist, so she failed to leave marks on the other party's body, and it was too late to obtain the other party's fibrous tissue. In addition, it was It fell into the pool water and soaked for a certain period of time. It is normal to find no traces on the dead body."

Ji Yunfan said: "But without these traces, I can't prove whether the deceased hit the handlebar by himself or was hit by someone."

Jiao Yang scratched his hair subconsciously, "Is there anything else on the body of the deceased that I haven't looked for... huh?"

Jiao Yang suddenly thought of the scene when he came to the cold storage that day, and suddenly raised his head to look at Ji Yunfan.

Ji Yunfan stared at his movements and was also taken aback for a moment.

The two said at the same time: "Hair!"

"Under the hair!"

Ji Yunfan put on the isolation suit, and took Jiao Yang and the others to the cold storage.

Ji Yunfan carefully tied a knot at the tail of the deceased's hair, and then shaved off the whole piece.

As soon as the back of the head was shaved, Jiao Yang saw a faint bluish dark mark on the back of the deceased's head.

At this moment, Jiao Yang's mood was like that of a traveler who had trekked in the desert for a long time and finally saw the dawn of greenery.

But even so, it is still early to solve the case.

Ji Yunfan patiently shaved off all of Wei Juan's hair, gradually showing more clearly the traces similar to five fingers, which became more and more blurred as they went down, but it could be roughly seen that it was a human palm print.

"found it!"

Hou Xiyong excitedly stretched out his hand and gestured, "Isn't this the outline of a slap?!"
