Detective from the future

Chapter 501 Arrest
When I returned to the Municipal Bureau, it was already past five o'clock in the morning.

Sun Jianzhong was temporarily detained, and his DNA was sent to the technical department for comparison.

The investigation of the case has also temporarily come to an end.

Ma Jingbo asked everyone to go to the dormitory to rest for a few hours before continuing the investigation at ten o'clock in the morning.

Ma Jingbo's proposal was unanimously approved by everyone. The dormitory of the Municipal Public Security Bureau is very close, just a few steps away.

Even after drinking strong tea and coffee all night, Han Bin's mind was a little heavy, and it was still necessary to get some sleep. How could he investigate the case when his mind was not working.

The conditions of the dormitory are naturally not comparable to those at home, two people share a room, Han Bin and Bao Xing share one, and Wang Xiao and Jiang Yang share one.

Han Bin didn't even bother to take off his clothes, and fell asleep in bed.

At 45:[-], Han Bin's mobile phone alarm clock rang.

Everyone washed up and arrived at the office at ten o'clock sharp.

Huang Qianqian has already bought breakfast for everyone, two meat buns, one tea egg, and a bag of milk for each person.

Ma Jingbo yawned, peeled the tea eggs, and said over and over again, "Let's discuss the case while we eat."

"The technical department just sent a report. The DNA of the truck driver Sun Jianzhong does not match the DNA of the victim. He is not the murderer we are looking for."

"As for why the deceased's mobile phone was in his car, I have two guesses. The first one is that he was also involved in the case and deliberately provided cover for the murderer. The second one is that he has nothing to do with the case. The murderer deliberately put The phone was thrown in his car."

"I personally prefer the second option."

Li Qin asked, "Ma Dui, are there any fingerprints on the phone?"

"Except for some sand, the phone is very clean, and no fingerprints of anyone were found..."

Bao Xing ate his breakfast, and said vaguely, "Doesn't that mean that the murderer is playing tricks on us, deliberately throwing the mobile phone on the truck transporting the sand, and let the police follow suit?"

Ma Jingbo concluded, "This suspect has a certain anti-reconnaissance awareness, and everyone should pay enough attention to avoid being led by the nose by him again."

Han Bin wiped his mouth, "If the suspect has a certain anti-reconnaissance awareness, why would he leave genetic material in the deceased?"

Ma Jingbo said, "Hey, this is a good question, what do you think?"

Li Qindao, "I think there are two situations. The first kind of suspect is a desperado. He doesn't care at all. He enjoys this kind of primitive possession more. The second kind of suspect is very confident, even if he left genetic material , the police were unable to compare successfully.”

Wang Xiao said, "Actually, even if the DNA can't be successfully compared, it can still provide us with some useful information. For example, among the suspicious persons who appeared at the time of the crime last night, there were men and women. Obviously, the male surname is more suspected. , you can start the investigation from the male surname."

"It's also possible that a gang committed the crime." Lin Qin said.

"Even if the crime is committed by a gang, the same male surname is more suspected, otherwise it is impossible to leave genetic material, and whether there is a female surname is still in doubt." Wang Xiao said.

Han Bin ate a tea egg in two bites, and it was very energy-consuming to use his brain. He went through the case again, went to the whiteboard and wrote a few words.

"The dead, the murderer, the informant, the police."

"The deceased was first stunned, then killed by the murderer, and then raped. After the murderer left, the report found the deceased and called the police. That is to say, before the police arrived, it was known that there were two people Been to the scene, the killer and the informant."

"During this period, the victim suffered three kinds of injuries. We instinctively connected the three kinds of injuries together, thinking that the same person did it, but what if it wasn't the same person."

"It can be simpler. The electric stun injury can be ignored for the time being, and only the latter two types of injury, homicide and healthy corpse, are considered."

"Assume that after the murder, the murderer did not violate the deceased, but left the swimming pool directly. At this time, if a man enters the swimming pool and sees a woman in a swimsuit lying beside the swimming pool, will he not be able to help but have evil thoughts in his heart. "

Although Han Bin said it more tactfully, everyone present understood that if the murderer did not leave genetic material, then only the security guard would have the chance to commit the crime.

Ma Jingbo said decisively, "Qianqian, check the security guard for information on buying train or plane tickets."

"Yes."

Huang Qianqian directly clicked on the police system, entered her account number and password, and easily found the security guard's ticket purchase information.

"Yes, he bought a ticket to Quincy at twelve noon today."

If it was just Han Bin's speculation before, now there is a certain basis.

Bao Xing smacked his mouth, "Tsk tsk, this buddy is really good at choosing a place, and he found a place with beautiful scenery and a place like spring all year round."

Ma Jingbo stood up, "Don't be poor, hurry up and arrest people."

If you really want him to fly to another place, and then change to other means of transportation, where can I find it in several cities?

Ten minutes later, Han Bin led a team to the airport to arrest Liu Yongshan.

Han Bin's doubts about Liu Yongshan accumulated bit by bit.

Last night, when Han Bin was taking notes for Liu Yongshan, he found that the other party was a little nervous. At that time, Han Bin thought that it was natural for the other party to be nervous when seeing a dead person for the first time.

Later, when the results of the autopsy came out, the victim was raped after death, which made Han Bin feel something was wrong.

The victim was obviously stunned, and the murderer really wanted to have bad intentions, so he could attack the victim at this time, there was no need to kill the victim before doing so.

The third doubtful point is that the murderer threw the mobile phone onto the truck transporting the sand, which diverted the police's attention from the investigation, indicating that the murderer had a certain anti-reconnaissance awareness, and it stands to reason that it is unlikely to leave genetic material.

But Huang Qianqian checked Liu Yongshan's ticket purchase records, and found out that the other party bought a ticket to Quincy, and the intention to escape was already obvious.

With Liu Yongshan's ticket purchase information, it is not difficult to arrest him. Han Bin already thought of the way to arrest him in the car.

In fact, Han Bin has a bolder guess, whether Liu Yongshan is the real murderer. Although this possibility is not high, it cannot be completely ruled out. The arrest also requires full confidence. The location of the arrest was chosen at the security checkpoint.

The arrest process went smoothly. After the security inspectors checked Liu Yongshan, Han Bin and others rushed forward and surrounded Liu Yongshan.

After seeing Han Bin and the others, Liu Yongshan was so frightened that he couldn't speak fluently.

Looking at this appearance, Han Bin knew that something was wrong with him, so he was handcuffed directly. When he was being escorted to the car, Liu Yongshan's legs were weak and he was struggling to walk, so Bao Xing and Jiang Yang helped him up. car.

After returning to the Municipal Bureau, people from the technical department collected Liu Yongshan's DNA.

Then Han Bin struck while the iron was hot and brought him to the interrogation room.

The people in charge of the interrogation were Han Bin, Jiang Yang, and Bao Xing.

When Liu Yongshan entered the interrogation room, he lowered his head, unable to see his expression clearly.

"Bang bang." Han Bin knocked on the table, "raise your head."

After being escorted all the way, Liu Yongshan seemed to have regained some courage and forced a smile, "Officer Han, why did you bring me to the police station? I bought a ticket to another place. You are not delaying me." Well."

"Now that I know it's delaying you, why didn't you tell me at the airport?" Han Bin asked back.

"I didn't think about it that much at that time." Liu Yongshan lowered his head.

"It's not that you didn't think too much about it, but that you were frightened." Han Bin said coldly.

"Yes, it's my first time flying by plane, so I'm bound to be a little scared."

"Okay, just keep pretending to me here." Han Bin walked to the front of the desk, staring at him sharply, "Liu Yongshan, we arrested you because we had enough evidence, even if you refuse to recruit, You can be condemned as well."

Liu Yongshan took a deep breath, "I...I don't know what you are talking about."

Han Bin could tell when he was at the airport that this Liu Yongshan was not very courageous, so he said tentatively, "Liu Yongshan, don't pretend, you are the murderer who killed Li Yuan."

"I didn't." Liu Yongshan shouted.

"You went to the swimming pool that night and found Li Yuan swimming alone. You saw that she was beautiful and wore few clothes, so you thought badly, stunned her with an electric baton, and then raped her. In order to prevent her from calling the police, you even kept killing her."

"You're framing. I didn't do that at all. I didn't have an electric baton, and I didn't kill Li Yuan. Li Yuan was already dead when I went there." Liu Yongshan defended loudly, fearing that Han Bin would shirk all the charges. give him,

"You can't do this, you are wrong, I didn't kill anyone."

"Why didn't you kill and run away?" Han Bin asked back.

Liu Yongshan showed a tangled look, finally sighed, and said, "Last night, I saw the lights on in the swimming pool, so I went in and saw the girl lying by the pool, so I checked, she was gone. Not breathing, but still warm, I tried to revive her."

"I was holding her chest. She was wearing a bikini. She was so beautiful... I thought she was dead anyway, and no one would know. As long as I can control it, no one will know."

"As a result, I was so excited that I couldn't control it. I knew I had made a big mistake. I was afraid that the police would catch me based on DNA, so I pushed her into the water. I thought maybe this would destroy the evidence, so the police investigated I can't come out..."

Bao Xing looked serious and asked, "What do you do for work?"

Liu Yongshan said timidly, "Security, I am the security of the stadium."

"Bah!" Bao Xing spat, "You're so embarrassed to say that you are still a security guard like this, do you understand the meaning of security? You are discrediting your colleagues. Look at what you have done. It is worse than killing people." be bad."

"I'm just obsessed with ghosts. If that girl was still alive, I definitely wouldn't be like this at the time. I just couldn't help it for a while... I know I was wrong, and I will definitely change it in the future!"

Bao Xing snorted, and said contemptuously, "Don't worry, when you go to prison, you will have time to reflect slowly."
