Chapter 148

Case-handling center.

The leaves of the pothos in the corridor are black, like an old pothos that no one cares about.

Several veteran criminal police officers are imparting wisdom to Jiang Yuan.

In the interrogation room, what should be said and what should not be said.

In the interrogation room, criminal suspect Liu Chang has just finished reading the "Notice of Rights and Obligations of Criminal Suspects" and is in the process of signing it.

For a homicide case, even the County Public Security Bureau follows the textbook step by step as much as possible.

Otherwise, there are plenty of people who want to teach you how to do your job.

"What is your name?"

"Liu Chang."

"Have you used any other names or nicknames?"

"No." Remember the website

"Your ethnicity, date of birth?"

"I want to see that footprint expert." Liu Chang answered a few sentences, suddenly didn't want to cooperate, and shouted.

His expression was a bit flustered, his face was very pale, and he was wearing half-rimmed glasses, but honestly, he was still a quite good-looking young man.

He was also tall, which was quite an advantage.

Wu Junhao, who was wearing a police uniform and felt particularly strong and muscular, sat opposite him and coaxed him patiently:

"Didn't we agree? Let's take the statement first, and the person will be here in a while."

"It's been so long, he should be here. If he can't come, just say so directly, don't lie to me." Liu Chang's expression became very serious.

His pupils kept changing.

Wu Junhao was fierce when catching people, but very kind during interrogation, and continued to persuade: "There's no need to lie to you. If you want to see someone, doesn't the person have to be notified, then come over, and then come in to see you..."

"You said a quarter of an hour just now."

"It hasn't arrived yet."

"Then show me the time."

Wu Junhao froze again; it's not good to show this thing the time, as these are all basic rules of interrogation.

"Then I want to see my dad." Liu Chang made a new request, but this request made the faces of people inside and outside the interrogation room change.

A 25-year-old young man is still relatively easy to fool.

People who enter the interrogation room will have all kinds of whimsical ideas.

There are plenty of people who fantasize that their crimes are minor or feel they are innocent.

Liu Chang believed he was an accidental killer and was firmly convinced of it.

Only then did everyone have a basis for dialogue.

In a real interrogation room, there will be at least one idiot. This is the so-called interrogation room principle.

Liu Chang's brain suddenly straightened out a bit, which is the most nerve-wracking part.

If he refuses to confess, the subsequent case-handling process will be difficult.

It can be said that the happy lives of hundreds of cadres and police officers for the next week or two depend on Liu Chang's attitude at this moment.

As for Liu Chang's dad, he is a 50-year-old old fox in the officialdom, and he has a certain official rank; calling him difficult is an understatement.

"You are already 25 years old, you don't need a parent to accompany you." Wu Junhao suddenly said a sentence, piercing Liu Chang's sensitive heart.

He has seen too many teenagers who want to become men through language and roaring.

Prick the muscles related to "growing pains" a little, and they explode on the spot.

Liu Chang indeed became angry, his hands were shaking, and he roared: "I want to see the footprint person, hurry up!"

He stopped roaring about seeing his dad.

Wu Junhao breathed a sigh of relief, but he didn't dare to interrogate anymore.

Liu Chang's father was actually being interrogated in the room next door.

Liu Chang's father was much more seasoned.

He looked like the kind of leader with a little power; when he was just caught, he still had an official tone and was a bit fierce.

Such people have iron-like willpower in most situations, like feces in a pile of stones exposed to the scorching sun—slippery on the surface, seemingly hard on the outside, but empty when broken open.

However, for Old Wu, he was not worried about the interrogation of Liu Chang's father.

For someone like him, the simplest method is the water-grinding effort; no matter how hard the feces are, after soaking in water for a few days and stirring with your hand, it dissolves.

Old foxes have had power and money, are corroded quickly, and have many weaknesses.

Instead, it's young people like Liu Chang whose emotions change drastically, are very unstable, and are easy to retract their confessions.

He was still confessing everything in the car just now, but changed after entering the interrogation room; heaven knows what strange performance he will have next.

People who have killed have some problems with their psychology to a certain extent.

Wu Junhao doesn't want a clear homicide case to turn into a muddled case like snot.

Outside the interrogation room.

Professionals also realized that Liu Chang's emotions were uncontrollable, so they hurriedly gave Jiang Yuan a few more instructions and let him in.

A group of people stared at the monitor expectantly, clenching their fists, looking as serious as fans of a home team.

Jiang Yuan knocked on the door and entered the interrogation room.

Wu Junhao used the largest interrogation room, long and wide, with iron railings blocking one-third of the way from the door.

Liu Chang sat inside, couldn't find a window, and the spotlights overhead made him irritable.

The so-called "tiger chair" was also filled to the brim.

A 1.93-meter-tall man pulled the chair to the highest, his legs were overflowing, and his arms were placed on the table, also extending a length, so that the handcuffs could almost not be locked.

The two restraint straps behind were fine, but Wu Junhao didn't put them on him.

This thing is uncomfortable when put on, and the discomfort is definitely much higher than a seat belt; he was afraid that Liu Chang, who surrendered, would be unhappy.

Before the criminal confesses, the police are all like caring big brothers.

Only after he falls into their palms will the police show their fierce side.

Mature police officers are usually like mature scumbags.

And immature police officers are usually like immature scumbags.

Jiang Yuan is also very tall. The moment he entered the door, under the illumination of the strong light, it was almost like seeing himself sitting inside...

Liu Chang was about the same; in the blink of an eye, he almost saw another himself walk in.

The two seemed to be stunned face to face.

Liu Chang was also a proper second-generation official in a small place, and he also looked like he had no worries about food and clothing.

"This is our footprint expert, Wu Wu Fa Yi Jiang." Wu Junhao signaled Jiang Yuan to sit beside him and introduced him to Liu Chang.

"How old are you?" Liu Chang's pupils shrank, but he asked first.

Jiang Yuan saw such a young suspect. Although he had read the case file and heard about it all the way, including seeing it outside, the feeling was still very strange when facing him face to face.

"24 years old."

"Younger than me?" Liu Chang suddenly looked at Wu Junhao excitedly! His feet were also shaking:

"Who are you fooling? Is it interesting to get a fake one?"

Wu Junhao was stunned, then patted his own thick forehead with his big hand.

"You should have said so earlier. We have so many people, it's convenient to get a fake one. Do you think an expert should be 40 or 50 years old, preferably with gray hair, or the kind with little hair?"

Wu Junhao wiped his greasy hair and continued:

"If I had known, I would have gotten a bald police officer, and I wouldn't have invited Jiang Yuan from so far away. We lack everything in our team, except age and baldness."

Liu Chang was speechless.

And he felt that this burly man made a lot of sense.

He looked at the young man opposite him seriously again.

"How did you see my height? I heard that the previous footprint expert was also a famous footprint expert in the province."

His question was still a bit professional, indicating that he had indeed learned about it in advance.

Jiang Yuan asked back: "Why do you care about this?"

"Just want to understand. I am much taller than normal people. When the incident happened, I saw footprints all over the floor, and I knew there was a problem." Liu Chang said seemingly calmly: "Reporting a lower height was my own decision."

With just this sentence, Liu Chang revealed a lot of information.

If his words are true, first of all, it shows that Liu Chang didn't know the previous fingerprint expert's judgment on his height.

In other words, his father's connections didn't reach the level of leaking case information.

Chen Wenming's judgment that day was 178 to 185; Liu Chang was just too tall, otherwise, if he had reported 185, he would have entered the range directly. At that time, the special task force's screening intensity for him would definitely have been several times greater.

Secondly, Liu Chang said that reporting a lower height was his own decision, which shows that someone else decided other things for him.

Most likely his parents.

In other words, this sentence proves that his parents did indeed cover for him.

Finally, Liu Chang also revealed his psychological state.

It's not new for young people to want to decide their own future and use their own cognition to confront the world.

It's just that some people eventually became the Father of the Nation—speaking of Sun Yat-sen.

Some people eventually were just a murderer—speaking of Qin Wuyang.

Jiang Yuan looked at Liu Chang even more deeply.

From the feeling of facing him, could this guy still want to learn something?

Does he think he can get out after accidentally killing someone and wants to prepare for the next time?

"If you don't say it, I won't say it either." Liu Chang felt he could handle Jiang Yuan.

Jiang Yuan smiled and said: "Judging height is actually a systematic work, it's all in the books."

"I just want to hear you say it."

"Okay, the simplest point is to judge height based on foot length. There are some empirical rules."

Jiang Yuan said slowly: "For example, in ancient China, there was 'standing seven, sitting five, kneeling three,' which means a normal person's height is seven times the head length, and the foot length is actually about the same as the head length."

"Isn't it said that some people have nine-head proportions?"

"That's an exception. Let's talk about general rules first."

Liu Chang expressed approval: "Good, so it's multiplied by 7?"

"Shanghai people multiply by 6.75, Northeasterners multiply by 6.876, Shaanxi people 6.734, Chongqing 6.856..." Jiang Yuan gave a comprehensive answer directly.

"But I wore shoes that day!" Liu Chang was most concerned about this.

"And I wore shoes smaller than normal, the shoes pinched my feet, and the size was different from usual."

"Can you tell?"

"I can tell." Jiang Yuan nodded and asked: "Should I continue?"

"You speak."

"To further judge height, we need to add foot width data. Although your feet are relatively long, they are wider than normal. This is another detail point."

Liu Chang listened to the young forensic doctor in front of him talking eloquently and actually agreed a bit:

"Chinese people's feet are generally wider than Europeans', so foreign brand shoes are easy to pinch."

His foot width exceeded the standard, and he felt it deeply; it was not easy to buy shoes.

"Then there are the sole area and the metatarsal width. The usability of the regression equation formed by adding these two data items is relatively high." Jiang Yuan also spoke quite carefully; anyway, they are all public information.

And according to the interrogation experts, chatting with Liu Chang for a while at this time is beneficial.

Liu Chang frowned when he heard the regression equation and said: "You are still talking about average data, right? How do you know my height is 193?"

"The real conclusion should be 191 to 195; I judge 193 is the most probable." Jiang Yuan replied.

He also explained: "Actually, it's still an element of experience; in addition, there are pressure marks, and stride length..."

... The leaders outside the interrogation room were all confused, some were stunned, some felt it was awesome, and watching the young forensic doctor and the young criminal suspect talk inside, they really saw a sense of urgency like in a TV show.

Wonderful and indescribable.

"Can you explain in detail?" Liu Chang asked.

"It's your turn to speak." Big muscle Old Wu interjected and said: "Let's fill in the interrogation record first, and you can chat in detail later."

"Fill in what." Liu Chang's body leaned back slightly, but the iron chair couldn't lean back, making him frown slightly.

"First tell me, why did you kill someone." Wu Junhao didn't follow the order and asked directly.

Liu Chang curled his lips: "Didn't I say it already?"

"This is a formal interrogation. Only if you say it now can it be considered that you have surrendered..."

Liu Chang raised his head and said slowly: "I was also an idiot at the time, I bumped into his son, scolded each other a few times, and that kid was dressed in rags..."

Recalling the scene seven years ago, Liu Chang also had a trace of regret, shook his head, and said: "In short, I wanted to make up for it. That day, I happened to be near there, so I rode a bicycle to his house, and happened to run into his dad. The old man wanted to fight me, so I could only fight back, and accidentally..."

"How did you know where his house was?"

"That kid said it himself. He said that after getting off the county road, there are two big lions with wings, that's their house." Liu Chang's voice became weaker and weaker...
