Detective: Open your eyes, I am handcuffed in the interrogation room.

Chapter 638 Qian Dakang's suspicion increases sharply

The time comes at night.

Chen Yi and Lu Zhengkai were having dinner in the conference room. The external investigation was still going on, and they would call if there was any new situation.

At this time, the basic information of two people was placed in front of Chen Yi, and he read it while eating.

One of them is Qian Dakang, and the other is Qian Dakang’s son Qian Yu.

Qian Dakang came into the police's sight, and his son Qian Yu naturally could not be ignored. Theoretically speaking, if one of Qian Dakang's motives for committing the crime was to avenge his son, then Qian Yu might also avenge himself.

"There is no disability or sequelae. Qian Yu was admitted to Yangcheng University. The perpetrators were punished by law... Captain Chen, isn't the motive of revenge a bit far-fetched? And so far, no connection between Ji Jingfu and Qian Dakang has been found."

Lu Zhengkai said that this did not conform to normal logic, unless going to the hospital had caused irreversible and significant impact on the father and son.

From a practical point of view, Qian Yu's life is relatively smooth. As a top student of Yang University, he has a promising future. There is really no need for Qian Dakang to give up his good life and wipe out Ji Jingfu's entire family. Once the truth comes out, it will deal a fatal blow to Qian Yu's future. What's more, Qian Yu has not graduated yet and is in his third year of college.

Qian Yu is even less likely to be suspected. A college student who is receiving higher education and has not yet entered society should not do such an inhumane thing.

Currently, an investigation team has gone to Yangcheng University to understand the situation and confirm Qian Yu’s alibi on the day of the incident.

Chen Yi did not answer Lu Zhengkai's question and said, "Let's talk after the investigation results come out. We still have too few clues."

Qian Dakang is only the first suspect held by the task force, but he is not necessarily the murderer. As the investigation deepens, perhaps a second or third suspect will appear.

At this time, He Shixin was standing in front of a pile of newly dumped garbage, searching carefully with a dozen police officers.

What I'm looking for is a damaged hard drive.

Two hours ago, he rushed to the repair shop and asked for help in repairing the surveillance camera, but he didn't expect that Qian Dakang had already found someone to repair it and installed a new one after Zhuo Yun left.

It's like a race against time.

Instead of repairing it earlier or later, they waited until the murder happened and the police came to investigate before repairing it. This made He Shixin suspicious.

The old surveillance camera at the repair shop was installed many years ago. It was connected to a computer and the surveillance video was saved in a hard drive. According to Qian Dakang, the surveillance camera at the repair shop was completely damaged. Not only was the surveillance camera broken, but even the hard drive was broken.

Regarding this matter, He Xin specifically went to ask the engineer who installed the new surveillance camera, but the other party had never seen the hard drive.

He Shixin always felt that something was wrong with Qian Dakang, and he needed to see with his own eyes what the damaged storage hard drive looked like.

The hard drive was thrown into a city trash can on the side of the road, which was taken away by a garbage truck and just dumped at the landfill.

Looking at the mountain of garbage, He Shixin stretched his joints and continued to search.

……

News came from the investigation team of Yangcheng University.

Qian Yu was not at school in the afternoon and evening of the incident. He said he had returned to his hometown.

Qian Dakang's hometown is Xintou Town, not far from the repair shop. His grandfather passed away and his grandmother lives here. Qian Yu has a good relationship with his grandmother and goes back almost once a month.

Qian Yu stayed at his grandmother's house until nine o'clock in the evening. He left and went back to his own home only after his grandmother fell asleep and went to school the next day.

The investigation team went to Xintou Town to meet Qian Yu’s grandmother. After questioning, they confirmed that Qian Yu had returned at around 11 o’clock in the morning and left at around 9 o’clock in the evening.

"Lu Zhi, I think Qian Yu's alibi is not sufficient." The experienced investigator expressed his opinion, "According to Qian Yu's grandmother, after Qian Yu came back to eat, he went back to his room to play with his phone and did not come out until around 6pm when he was having dinner. By then, the tragedy was over.

I went to the room and saw that the window in the room was a single wooden window, which was large enough for an adult male to enter and exit. Outside the window was a low wall, which was very easy to climb over.

Unfortunately, there was too much debris on the ground and I couldn’t see clearly if there were any footprints.”

Although it is just speculation, the investigation must be rigorous.

Since Qian Yu could theoretically sneak away to commit the crime, he cannot be ignored. Moreover, Qian Yu’s grandmother’s home is not far from Ji Jingfu’s home. It is only a 1,800-meter walk to the urban village.

Lu Zhengkai: "Did he bring his bag when he went back to his grandmother's house?"

Investigator: "No, I came here empty-handed."

Lu Zhengkai said, "Have the technical detectives collect fingerprints and footprints from the windows and window sills. You guys walk around and look for any suspicious items or bloodstains."

Investigator: "Yes! Lu Zhi!"

The phone hangs up.

The problem between this father and son is a bit big. How is it possible that a repair shop owner and a college student do not have a perfect alibi on a weekday afternoon?
Could it be such a coincidence?

"Judging from the traces at the scene, there is only one suspect, right?" said Lu Zhengkai.

Chen Yi said: "There is no evidence to prove that there are two murderers."

……

Landfill.

"Captain He! Found it!"

After searching for more than an hour, a police officer picked up a black object. After carefully examining it, his eyes lit up and he shouted immediately.

Hearing this, everyone else stopped searching, stood up and turned around, all breathing a sigh of relief.

The job of rummaging through garbage is not easy, mainly because it is very tiring to bend over for a long time.

When Xin strode over.

After taking the hard drive from the police officer, He Shixin checked the damaged part under a strong flashlight. The damage was very serious and could not be repaired.

Not to mention technicians, even a layman can see that the hard drive was damaged by human factors.

"It's hilarious! It was broken by a screwdriver! There are also traces of it being broken by pliers!"

"Everyone follow me back to the repair shop!"

After confirming that the hard drive was obviously damaged by human factors, He Xin's face turned grim. He felt that his IQ was insulted, and immediately took his people back to the repair shop.

On the way, he called Chen Yi. After a brief exchange, the Municipal Bureau immediately applied for a search warrant and prepared to conduct a carpet search of Qian Dakang's repair shop and even Qian Dakang's home.

Lying to the task force means that Qian Dakang is highly suspected of committing the crime and he needs to be investigated in depth.

When I got to the repair shop, the light was still on, but it was closed.

When He Xin quickly walked through the construction site and entered the inner room, he found Qian Dakang's wife was cleaning the table. The air was filled with the smell of alcohol and cigarettes.

On the table, leftovers were scattered about. The two men were drunk and lying on the sofa in all directions.

Qian Dakang was among them.

Seeing this, He Xin frowned: "What's going on?"

Qian Dakang’s wife explained that they were just getting together with old friends and they drank a little too much without realizing it.

He Xin glanced at Qian Dakang's friend. He was sleeping soundly with a ruddy face and smacking his lips as if he was dreaming. He showed no intention of waking up. He looked at Qian Dakang again. He was sleeping even more soundly and even started snoring.

"Who is this?" He Xin asked.

Qian Dakang’s wife: “Lao Zhang… Zhang Menhai, who runs a convenience store across the street, these two have known each other for many years and often drink together.

Police comrade, why are you here again? We are doing business honestly and will not do anything illegal or disorderly. "

He Xin knew that it was impossible to interrogate Qian Dakang before he sobered up. Was it intentional?
It is not a good idea to escape police detection by getting drunk, because you will wake up eventually.

"How did the surveillance camera in your repair shop break down?" He Xin asked Qian Dakang's wife.

Woman: “I don’t know. I don’t understand.”

He Shixin: "Has Qian Dakang behaved in any suspicious way in the past two days? For example, he spent a long time fiddling with something in front of the computer, or touched the surveillance camera himself."

The woman shook her head: "I didn't notice."

He Shixin: "Yesterday afternoon, was he at the repair shop? Think it over carefully. If you cover up for him, you will go to jail!"

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

The woman was helpless: "He is here, he is really here, right under my nose, I am not blind! You...what are you looking for?!"

He Xin was too lazy to judge whether the woman was lying or not. After the search warrant was delivered, he immediately led a team to thoroughly investigate the entire repair shop.

Seeing more police coming, Qian Dakang’s wife was a little confused. She didn’t dare to stop them and just stood not far away and watched timidly.

"Focus on finding bloodstains and sharp objects!"

A lot of people came to investigate this time, and with Su Ying and Cheng Hanjun here, as long as there are traces, they will definitely be found.

Municipal Bureau, conference room.

It was almost early morning, and more than thirty hours had passed since the crime occurred.

After learning that Qian Dakang lied, the task force command focused most of its attention on Qian Dakang and analyzed his crime process.

Tang Hongyi came, and Zhou Yebin was there too.

It is very good news that a major suspect has been found.

Lu Zhengkai said: "Since Qian Dakang chose to destroy the surveillance of the repair shop, combined with his confession, it means that he left from the repair shop, took the shortcut into Ji Jingfu's house with the tools he used to commit the crime, and returned to the repair shop after killing four people.

Then, there is a high possibility that there is residual evidence in the repair shop, such as the murder weapon, shoe covers, gloves, coats, etc. He must deal with them.”

Tang Hongyi: "If it was packed and thrown directly into the trash can, it should still be in the garbage disposal plant in the suburbs. In 30 hours, there is a good chance that it will be found."

This is one of the reasons why the longer it takes to solve a case, the fewer clues there are. If ten days or half a month had passed, the old garbage would have been dealt with and it would have been impossible to find it again.

Lu Zhengkai thought for a moment and said, "Let's wait for Captain He's search results. If we find nothing, we will have to consider digging through the garbage mountain, which is a huge undertaking.

Also, let's hear what Qian Dakang has to say when he sobers up. Maybe he can't just lie and confesses. "

On the other side, Chen Yi leaned back in his chair and puffed on his cigarette. His voice rang out: "This guy still has the heart to drink with his friends? What's his friend's name? Zhang Menhai, right? When Zhang Menhai sobers up, we have to ask him what they talked about while drinking, and how much he knows about Qian Dakang."

The visit started in Xintou Town. Qian Dakang has just come into the police's sight, so Zhang Menhai is not currently included in the visit.

So far, Qian Dakang has done two things after the police came to his door. The first was to find someone to install new surveillance and throw away the old surveillance storage disk. The second was to find an old friend and get drunk until he passed out.

Although the phenomenon of speaking the truth after drinking has its limitations, from a psychological point of view, alcohol does have a certain inhibitory effect on the brain, especially on the cerebral cortex, making people's emotions and behaviors more susceptible to the influence of the subconscious, making it easier to express their true selves and speak the truth.

To put it simply, alcohol can lower a person's psychological defenses.

It is very strange that Qian Dakang dared to drink so much alcohol when he might face police interrogation at any time, unless he really has nothing to do with this case.

Even if he could guarantee that he wouldn't say the wrong thing when he was drunk, it would be better to be sober than drunk, right? Why take the risk?

"Maybe it's because of the alcohol that he was scared and made him braver?" Tang Hongyi said.

Chen Yi shook his head: "I don't think so. If he had committed this cruel murder, he wouldn't be so timid... It's weird. The more I investigate this case, the weirder it gets. I always feel like something is wrong."

Everyone fell silent.

In any case, Qian Dakang's lying behavior is a major discovery, and the possibility that he is the murderer in this case is getting higher and higher. Now we need evidence and to interrogate Qian Dakang.

Lu Zhengkai suggested: "Let's take him directly to the Municipal Bureau and let him sober up there. Since he got drunk himself, don't blame the task force for conducting a surprise interrogation on him while he was half drunk and half awake."

With the stimulation of alcohol, the task force would certainly not let go of this opportunity, since it was not the police who forced them to drink on purpose anyway.

Chen Yi agreed that Qian Dakang's lying was enough for the task force to arrest him.

After the order was issued, police officers from the repair shop directly carried Qian Dakang into the police car. His rough behavior caused his wife to complain, and she criticized the police for being inhumane.

You're already drunk, and you still want to take it away? Can't you wait until you sober up?

The search lasted for more than two hours, and Qian Dakang's wife was so sleepy that she fell asleep on the sofa. No findings were made so far.

When He Xin walked out of the back door of the repair shop, outside was the yard that Qian Dakang and his wife had fenced off themselves. Outside the yard was a large area of ​​undeveloped wilderness. Further away at the eleven o'clock direction, there were mountains. At the two o'clock direction on the right, there were a few scattered buildings. Judging from the map, those buildings were supposed to be planned as hospitals, but there had been no movement for a long time, and they might have been left unfinished.

"If Qian Dakang is the murderer, is it possible that he buried the murder tools? There is a large wilderness outside the back door, which makes it easy to do so." He Shi made a new analysis.

Once the analysis was done, action had to be taken. A call was immediately made to the Municipal Bureau, and soon more than a dozen police dogs were dispatched, spreading out in a fan shape from the backyard to the front.

At the same time, the investigation work in Qian Dakang's hometown was also proceeding in an orderly manner. When they learned that another investigation team was investigating Qian Yu, they found Qian Dakang's wife and woke her up from her sleep.

"Hmm? Is it over?" The woman opened her sleepy eyes. It was unknown whether she was careless or really knew nothing.

He Xin said directly: "When Ji Jingfu and his family of four came to your store, was Qian Yu there?"

"Qian Yu?" Hearing Qian Yu's name, the woman's sleepiness became dull. "Why are you asking about Qian Yu again? What happened to him?"

He Shixin: "Nothing, please answer the questions, this is for your own good."

The woman thought about it carefully and replied, "I can't remember clearly. I have so many customers every day that I have already forgotten."

He Shixin: "Does Qian Yu come to the repair shop often?"

Woman: "Whenever he's home, he comes. He comes back about five or six times a month. Yangcheng University is not far away, and you can get there by bus."

He Xin didn't ask any more questions. The woman's reaction was natural and he didn't find any problems for the time being.

Municipal Bureau.

Qian Dakang had already arrived and was indeed very drunk. The detachment arranged him to the lounge and had police officers on duty to keep an eye on him.

As long as the other party wakes up, he will face interrogation immediately.

　Thanks to 3144 for the reward.
