Detective from The Future

Back to the city bureau, it was already more than five 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 come to an end temporarily.

Ma Jingbo asked everyone to go to the dormitory to rest for a few hours, and then continue 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, and it is only a few steps away.

Rao poured strong tea and coffee all night, Han Bin's mind was also a little heavy, it is necessary to get a good night's sleep. If his brain is not bright, how can he investigate the case.

The conditions of the dormitory are naturally inferior to that of the family, with two people in a room, Han Bin and Bao Xing, and Wang Xiao and Jiang Yang.

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

At 9:45, Han Bin's cell phone alarm rang.

Everyone washed up and rushed to the office at ten o'clock.

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

Ma Jingbo yawned, peeling the tea eggs, and said over and over, "While eating, let's discuss the case."

"Just now the technical department sent a report that 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 cell phone was in his car, I have two guesses. The first is that he was also the person involved in the case, deliberately covering the murderer. The second is that he has nothing to do with the case. The phone was thrown on his car."

"I personally prefer the second one."

Li Qin asked, "Team, are there fingerprints on the phone?"

"Except for some sand, the phone is very clean, and no one's fingerprints have been found..."

Bao Xing was eating breakfast and said vaguely, "Doesn't it mean that the murderer is playing with us, deliberately throwing the mobile phone on the truck that transports the sand and letting the police follow along."

Ma Jingbo concluded, "This suspect has a certain sense of anti-reconnaissance, everyone must pay enough attention to avoid being led by his nose again."

Han Bin wiped his mouth, "If the suspect has a certain anti-reconnaissance awareness, why should the genetic material be left in the body of the deceased?"

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

Li Qin said, "I think there are two situations. The first type of suspect is a desperate person. He doesn't care at all. He enjoys this primitive possession. The second type of suspect is very confident, even if genetic material is left behind. , The police could not compare successfully."

Wang Xiao said, "In fact, even if the DNA cannot be successfully compared, it can 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 last name."

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

"Even if the gang commits the crime, the male surname is more suspect, otherwise it is impossible to leave genetic material, whether there is a female surname is still between the two." Wang Xiao said.

Han Bin finished a tea egg in two mouthfuls, using his brain is also very energy-consuming. He revisited the case and walked to the whiteboard and wrote a few words.

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

"The deceased was stunned first, then killed by the murderer, and then attacked by his surname. After the murderer left, he reported the deceased and called the police. In other words, before the police arrived, it was known that there were two people. At the scene, the murderer and the informant."

"During this period, the victim suffered three kinds of injuries. We instinctively linked the three kinds of injuries together and thought it was the same person, but if not the same person."

"It can be simpler. Corona injuries can be ignored for the time being. Only the latter two injuries are considered, killing and corpse."

"Assuming that after the murder, the murderer did not violate the deceased, but left the swimming pool directly. At this time, a man entered the swimming pool and saw a woman in a swimsuit lying next to the swimming pool. Would he be irritated? "

Although Han Bin was relatively euphemistic, everyone at the scene understood that if the murderer did not leave genetic material, then only the security guard had the chance to commit the crime.

Ma Jingbo said immediately, "Qianqian, please check the security guard and see if there is any information on purchasing bus or plane tickets."

"Yes."

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

"Yes, he bought a ticket to Quincy at 12 noon today."

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

Bao Xing smashed it, smashed his mouth, "Tsk tsk, this buddy will pick a place and find a place with beautiful scenery and spring all seasons."

Ma Jingbo got up, "Don't be poor, hurry up and catch people."

Really let him fly to another place, and then change to other means of transportation, where to find a few cities?

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

Han Bin's suspicion of Liu Yongshan was accumulated bit by bit.

Last night, when Han Bin made a transcript for Liu Yongshan, he found that the other party was a little nervous. At that time, Han Bin thought that the other party saw a dead person for the first time, and it was natural for him to be nervous.

Later, when the autopsy result came out, the victim was invaded by his last name after death, which made Han Bin feel a bit wrong.

The victim was obviously stunned, and the murderer was really thinking about it, and he could attack the victim at this time. There is no need to kill the victim before doing it.

The third point of doubt is that the murderer threw the phone on the truck carrying sand and diverted the attention of the police from the investigation. This shows that the murderer has a certain sense of anti-reconnaissance, and it is logically unlikely to leave genetic material.

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

With Liu Yongshan's ticket purchase information, it is not difficult to arrest him. In the car, Han Bin thought out how to control the arrest.

In fact, Han Bin still has a bolder guess as to whether Liu Yongshan will be the real murderer. Although this possibility is unlikely, it cannot be completely ruled out. The arrest also requires full assurance. It is safe, Han Bin. The location of the arrest was selected at the security checkpoint.

The arrest process went smoothly. After the security inspectors made a security check for Liu Yongshan, Han Bin and the others surrounded Admiral Liu Yongshan.

After seeing Han Bin and others, Liu Yongshan was already shocked, and he couldn't speak well.

Looking at this appearance, Han Bin knew that he must be in trouble, and he was directly handcuffed. When he was escorted into the car, Liu Yongshan's legs were weak and he was struggling to walk. Bao Xing and Jiang Yang were bothered by him. car.

After returning to the city bureau, the technical staff collected Liu Yongshan's DNA.

Then Han Bin hit the iron while it was hot and took him to the interrogation room.

The persons in charge of the interrogation included Han Bin, Jiang Yang and Bao Xing.

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

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

After being escorted this way, Liu Yongshan seemed to regain some courage, and forced a smile, "Police Officer Han, why did you bring me to the police station? I bought a ticket to other places. You are not delaying me. Well."

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

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

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

"Yes, it's the first time I'm flying on a plane. It's inevitable that I will be a little scared.

"Okay, you're still pretending to me here." Han Bin walked to the front of the desk, staring sharply at him, "Liu Yongshan, we caught you because we have enough evidence, even if you refuse to recruit, You can also be convicted."

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

Han Bin saw it when he was at the airport. This Liu Yongshan was not courageous. He tentatively said, "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 that Li Yuan was swimming alone. Seeing that she was beautiful and wearing few clothes, you started to stun her with an electric baton, and then carried out the surname invasion. In order to prevent her from calling the police, you did nothing but kill her."

"You are guilty. I didn't do it at all. I didn't have an electric baton, let alone killed Li Yuan. When I went, Li Yuan was already dead." Liu Yongshan defended loudly, for fear that Han Bin would be accused of all charges. give him,

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

"What did you run without killing?" Han Bin asked back.

Liu Yongshan showed a tangled look, and finally sighed and said, "Last night, I saw the lights on in the swimming pool, so I walked in and saw the girl lying by the pool. I checked it out. She was already Without breathing, but still having body temperature, I tried to save her."

"I was pressing on her chest. She was wearing a bikini. She was so beautiful... I thought she was dead anyway. No one knew. As long as I can control it, no one will know."

"As a result, I was so excited that I didn't control it. I knew that I had made a big mistake. I was afraid that the police would catch me based on my DNA, so I pushed her into the water. I thought that this might destroy the evidence and the police would investigate. Not coming out..."

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

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

"Bah!" Bao Xing sipped, "You are 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. See what you have done. It is more than murder. Be bad."

"I'm just a ghost. If that girl is still alive, I will definitely not be like this at the time. I just couldn't hold it back for a while... I know I was wrong, I will definitely change it in the future!"

Bao Xing snorted and said contemptuously, "Don't worry, when you go to jail, there is time to reflect slowly."
