Wu Fengrong's feet jumped up and rushed straight to his forehead. In any case, the killing of minors is an extremely heinous crime. Who would put a student to death with such great hatred and strong killing intent
"What does the autopsy report say?"
Zhou Yanling was looking through the autopsy report, and the ends of his brows were deeply inward, like two continents constantly approaching.
"A brain CT was done, and the fatal wound was determined to be on the back of the head. The violent blow caused a skull fracture and a tear in the supradural artery. The arterial bleeding was too fast, and the time from coma, suffocation to death should not exceed ten minutes. In addition, the internal organs and bones were not damaged, indicating that the murderer only used a blunt weapon to hit him, and he killed him with a very precise blow.
Before he died, he showed signs of fighting with people. There were bruises on the skin of his arms, neck, and thighs, and abrasions on his back, which may have been caused by a fall. The smudge on the corner of his mouth was detected as his own blood. The fight was fierce, and the jacket should have been torn off during the fight. Having said that, Zhou Yanling paused and continued to read: "A small amount of subcutaneous tissue and blood clots were detected between the fingernails of the right hand. It is likely that the murderer's skin was cut, indicating that the murderer would also have scars." "
"Has the murder weapon been found?"
"The police have confirmed that the murder weapon was a broken water pipe. It was less than 50 meters away from the scene of the crime. It should have been dropped by the murderer. The wound tissue on the back of Xiao Quan's head detected rust spots that fell off the water pipe. According to the Internet cafe, there was a broken water pipe in this shop a week ago. Because it affected the owner's normal domestic water use, the property was invited to repair it and replaced a new water pipe. The old one may be placed in the Internet cafe. In the pile of junk at the back door, the murderer picked it up and used it."
Wu Fengrong asked keenly: "Why do you say 'handy'? How can you confirm that the murderer did not intend to kill?"
Zhou Yanling analyzed: "The two people should have fought with their bare hands first, and then the murderer picked up the water pipe and gave it the last shot. If the murderer started the murder with a weapon, Xiao Quan's first reaction should be to run, because he has no weapon in his hand. There is a huge disparity in strength, and normal people would just run away. If the murderer fought him with a weapon, there should be more than one blunt impact on Xiao's body. So, it is possible that they just wanted to fight at first, and then Later, when the fight was fierce, the murderer acted impulsively. This is one of them."
"Second, the motive for the deliberate murder is hard to fathom. Have you watched the video of the victim's parents being interviewed? It's available on the Internet. Xiao Quan is a very ordinary student with good grades but not top-notch. He usually has no hobbies, only He went to the Internet cafe to play games on the weekend. It happened to be Friday, so he went to the Internet cafe as usual after school, and his parents knew that he was in the Internet cafe that night, and his parents allowed him to go. A well-behaved child with no place to blame, Who could he offend and forge such a big hatred to premeditate murder? Of course, many hatreds in this world are unbelievable in themselves, and some people have extreme thoughts and kill for bigger things. I can only say that I hope this child I didn't mess with such a person."
Wu Fengrong took the case information from him and read it carefully page by page. Zhou Yan heard the sound of page turning, which combined with the iron wheel of the train to form an eternal sound of reincarnation. Life, he thought, was like that, swiping over and being carried away with a rumble.
"Keep things that don't have evidence. You have to explain this first." Wu Fengrong pointed to the inspection report and said, "Your fingerprints are left on the murder weapon. What happened? Did you touch that water pipe?"
Zhou Yanling laughed: "I have touched Xiao Quan's face, in order to probe his nose and mouth to breathe, I admit it, but I have never seen that broken pipe. The alley is so dark, where would I pay attention to any water pipes, I guess it is The murderer stuffed it into my hand and got fingerprints in my clip. That way the police would find me through the weapon and list me as a suspect."
After a while, Wu Fengrong closed the file folder with a snap, and his bangs were blown up by the small wind that was closed, and were raised above his head.
He just said with a pinch of bean sprout-like hair: "People were killed next to an Internet cafe, most likely someone in the Internet cafe. Now there is definitely no way to go to the Internet cafe to watch the surveillance video, With such a large carload of people, there are a total of about 300 people, it is a fantasy to investigate one by one, and we can only use the exclusion method to narrow the scope first, identify a few suspects, and then ask carefully."
Zhou Yanling agreed: "Since the murderer is going to Baihe, the people who are not going to Baihe can leave the car first. Do you have the passenger information? Can you know the destination of each of them?"
"This is not difficult, but not many can be screened out according to this condition." Wu Fengrong explained: "Baihe is an industrial town, and there were not many people visiting at this time, but after the opening of a protected forest area to develop tourist attractions the year before last, There are tourists. Today is the second day of the National Day holiday. Guess how many people are not going to Baihe on this train? I bet you, more than 80% are going to play. If you go from the front of the car to the car If you take a walk at the end, maybe you can still see college students organize group activities to play, the school activities are not funded much, the students are eager to buy hard seat tickets, and dozens of hours of men and women playing together will soon pass.”
Zhou Yanling's heart sank with his words. There were two dangerous people in the car. In the event of an accident, neither he nor Wu Fengrong could be responsible for these students. Only one child died, how much confidence can they have to play games with the lives of other children
"The murderer is likely to be mixed in this car, pretending to be traveling to Baihe, maybe he is alone, maybe he has a partner, it's hard to tell." Zhou Yan had to sigh while listening to the messy case files.
Wu Fengrong began to rearrange his thoughts: "First, according to the content of the text message, the murderer got on the bus with you in Tongzhou, so the people who come up from the station can be excluded, we just need to look for the existing passengers. Second, According to the autopsy report, there are traces of subcutaneous tissue and blood clots in the nails of Xiao, so there is a high possibility that the murderer also has scars. The injuries may not only be scratches on the nails, but also fractures, bruises, swelling, and abrasions. ."
The traces of subcutaneous tissue and blood clots are not enough to detect DNA for comparison, and can only prove that the murderer may have a wound. But this wound should be easy to identify. In this weather, there are at least two layers of clothes on the body. If the coat is still a little thick, it is difficult to put your hand into the clothes and scratch people, so the wound should be on the exposed skin, such as the face, neck, chest, hands, small arm etc. Being scratched by a nail will not be very serious and inconspicuous. If you don't pay attention to it, it will not cause suspicion, and even the murderer will not deal with it too carefully. If it is wrapped too tightly, it will be strange. As long as you patrol the car once, you can clearly know.
It doesn't matter that there are many people going to Baihe, but there are probably not many people with injuries.
Zhou Yanling got up and walked outside, Wu Fengrong grabbed him with one hand.
"I have another question. The text message said that you must find someone before you reach Baihe Station, otherwise it will be futile, why?"
"What do you want to say?"
"He is implying that if he arrives at the station, no one will be caught. Why can't he be caught when he arrives at the station? Even if the murderer escapes from the province, he can be caught across the province, so why is he safe when he arrives at Baihe? Because someone can protect him If the murderer also knew that he would be safe in Baihe, why did he take this train? It’s less than three hours by plane and eight hours by high-speed train, so why stay up for two days and one night?”
"Because his economic conditions are particularly poor?"
Wu Fengrong sneered: "You have murdered, the Ministry of Public Security wants you all over the country, there is a place to ensure your safety without going to jail, are you afraid of spending a few hundred or even a thousand dollars? It's just to borrow some money from a friend by emptying out your family. Can’t afford a plane ticket? There will always be money, but if you go in, you will have nothing.”
That leaves only one possibility—
"He can only take this train, he has serious reputation problems and can't take planes and high-speed trains."
Wu Fengrong also stood up: "I'll go to patrol the car first, and then I'll go back to the back-end system to find the passenger information, and compare it with the blacklist to find out. You wait for me here, and I'll be back in an hour at most."
After saying that it was his own work for a long time, Zhou Yanling interrupted him: "I'm going to patrol the car, you just go to the backstage."
"No. The murderer knows you. If he sees you in the car, he will risk calling the police. There are so many flight attendants and marshals outside. I have let them all see your photos. You are better now. Don't show your face, the more flamboyant it is, the more dangerous it is."
"At least let me do something, I can't keep you busy alone."
Wu Fengrong thought for a while, turned on the computer on the desk, and entered his account and password, which was the internal system background of the Ministry of Railways: "Here can check the information of all passengers, the name, ID number, destination, etc. Yes, you can find the blacklist by yourself. There is no automatic comparison screening system, so you can only look at each one by yourself. I will discuss with the vice-commander later. I can’t explain some things clearly, so you can make them up for the time being. Lies and fools, the rest is up to you."
Zhou Yanling leaned over and kissed the corner of his mouth, and Wu Fengrong raised his head to take it. He smoothed the wrinkles of Zhou Yanling's clothes and lowered his voice: "Be smart, be careful, and don't let anyone find you here. I'm still worried The reason why Baihe is safe is that there is a wealthy and capable person to shelter this guy, that's fine, but there is still another possibility..."
Zhou Yanling's voice suddenly became very heavy: "He will die when he reaches Baihe Station."
Of course the dead can't be caught.
