Pingjing City Railway Station.

"Hello, I'm Zhang Bo, the conductor of G308."

As soon as Shen Zezhi took Ji Ziyue and Sang Yunqing to the G308 train, the conductor came out to greet them. Shen Zezhi shook hands with him: "Hello, I'm Shen Zezhi from the special case team." Where is the site? ”

Zhang Bo turned around and led everyone to the car: "Here, you come with me." ”

Shen Zezhi and the people of the special case team followed the train station to the carriage where the accident occurred, the No. 5 carriage.

Zhang Bo walked to the bathroom and let Shen Zezhi look inside: "This is it." ”

The bathroom door was ajar and there was a body inside. The bathroom is small, and the man is half leaning against the wall with his feet spread out and half lying on the ground. His face was pale, his eyes were wide open, and he looked surprised by his expression. The man's neck was blurred with blood, and a large amount of blood flowed out of the wound on his neck, accumulating a large amount of blood on the floor of the bathroom.

Sang Yunqing walked in, she squatted next to the corpse and looked at it for a while, then took out a pair of tweezers from the box she was carrying, she carefully used tweezers to clamp something in the wound of the corpse and slowly pulled it out.

Shen Zezhi leaned down to look at the thing on Sang Yunqing's tweezers: "What is this?" ”

Sang Yunqing said: "Metal filament." ”

Shen Zezhi glanced at the corpse and said, "This is the murder weapon?" ”

Sang Yunqing nodded, Shen Zezhi straightened up and went to the side of the train station, and Ji Ziyue went to the bathroom to check the scene.

Shen Zezhi asked, "What's the situation?" ”

Zhang Bo took off his hat and wiped his sweat and said: "Our train is from Rongcheng to Pingjing, and the bathroom must be locked when the car is about to arrive at Pingjing Station, but there are people inside, and the conductor of the No. 5 carriage waited for a while, and when he arrived at the station soon, the conductor knocked on the door, but there was no response inside." We were worried that the passengers inside would faint in the train due to a sudden illness, and when we opened the door with the key, we saw that this was the case. The conductor was silent for fear of causing a commotion, so he locked the door and informed me, and we called the police. ”

Shen Zezhi said: "So you mean that the bathroom door is locked from the inside?" ”

Zhang Bo nodded, and Shen Zezhi asked, "I saw that there is a window in the bathroom, can that window be opened?" ”

"Yes, but ordinary people won't do it, and besides, the speed of the high-speed rail is too high, even if someone opens the window, they don't dare to jump out."

Shen Zezhi stood in the carriage and looked at it and asked, "Did you check the passengers after the body was found?" Are there any fewer passengers? ”

Zhang Bo said: "We immediately missed the passengers, but some passengers got off the train from the previous station, so we have no way to determine whether there are fewer people." ”

Shen Zezhi sighed: "Do you know the identity of the deceased?" ”

Zhang Bo said: "I don't know yet, we don't dare to touch the things on the scene." ”

Shen Zezhi nodded, and at this time, Ji Ziyue came out of the scene, carrying the bag next to the corpse in his hand. Shen Zezhi and Ji Ziyue casually found a place to open the bag and look at it, there were a few documents in the bag, it was a sales contract for an electrical appliance company called "Xingyang", and there was a black wallet. Kiko opened her wallet and saw the identity of the corpse.

The deceased's name is Wang Liang, 33 years old this year, and his hometown is Pingjing. In addition to an ID card, there are also three bank cards, a stack of business cards and several renminbi in the wallet.

Shen Zezhi took the stack of business cards over and flipped through them, and he took out one from it and showed it to Ji Ziyue. This business card happened to be the business card of the deceased, and it read: Wang Liang Xingyang Electric Appliance Co., Ltd. Sales Manager.

"A sales manager for a small company?" Kiko said in confusion.

Shen Zezhi stood up and said, "Check the scene again, and we'll talk about it in the group." ”

Kikotsu immediately went over and ordered the police who came with him to clean up the scene. Sang Yunqing has already completed the preliminary autopsy. Shen Zezhi asked, "What's the situation?" ”

"The death did not last more than an hour, and the cause of death was a wound in the neck. The wound was very deep, not only the major arteries were cut off, but also the trachea was broken. The murder weapon was the thin wire I had just pulled out of his wound. It is not clear exactly what the material is, and the answer will not be given until after testing. There was also a fight between the layers before the death of the deceased, but the fight was short-lived. So the site looks very clean. In addition, the deceased was in good health. ”

"Robust?" Shen Zezhi wondered, can a sales manager's body be described as robust?

Sang Yunqing cleaned up his things: "What does he do?" ”

"Sales Manager."

Sang Yunqing hesitated for a moment and said, "Then he must love fitness." ”

After the police handled the scene, Shen Zezhi returned to the special case team with people. The special case team had just finished handling a case last week, and had only taken a three-day break, and was summoned back immediately after receiving the case.

In the conference room, Shen Zezhi asked Ji Ziyue to tell everyone about the situation at the scene.

Ji Ziyue put the photos taken at the scene on the PPT and explained: "The deceased Wang Liang, male, 33 years old, from Pingjing City. Now he is the sales manager of Xingyang Electric Appliance Co., Ltd. He got on the train at 7:58 a.m. today, May 11, and took the G308 train from Rongcheng to Pingjing City. The train runs for six hours with five stops in between. When the train arrived at Pingjing Station, the conductor found dead in the bathroom of car No. 5. We found his ticket from the deceased. Now according to his seat number, the person who is sitting near him is being checked. ”

"These are photographs of the scene of the death of the deceased, and according to our observations, the bathroom where the deceased died was buckled from the inside, and there was no trace of the window of the bathroom being opened. So it can be characterized as a murder in a closed room. ”

"Murder in a closed room? Cool! Guan Xin exclaimed. Shen Zezhi's eyes turned to him, and Guan Xin immediately stuck out his tongue.

"Guan Xin, how is the contact with the deceased's company?" Shen Zezhi asked.

Guan Xin immediately said: "I have been contacted, Wang Liang was only appointed by the company to go to Pingjing City this morning to discuss business, and he has money for the goods." Tickets are also bought on an ad hoc basis. So murder is unlikely. ”

Ji Ziyue said: "But the deceased's property is all on his body, and nothing has been lost, his wallet and mobile phone are all by his side." ”

Qi Kai said: "So it can't be for money." ”

Zhao Jiyong leaned back in his chair and looked at those photos and said: "The purpose of killing is just a few, murder for money, vendetta killing, love killing." Then there's the killing of passion. Murder for money can now be ruled out. If it is a murder of passion, at least there must be an argument with someone. But according to the conductor's transcript, there was no dispute in car No. 5. So it can be ruled out that passion kills. ”

Ji Ziyue said: "So there are only two possibilities left: vendetta and love killing." ”

"Guan Xin, can you contact Wang Liang's family?" Shen Zezhi asked.

Guan Xin shook his head: "According to the deceased's colleagues, Wang Liang has no relatives in Rongcheng, and he doesn't seem to have particularly good friends. ”

"The deceased seems to be from Pingjing, can you find out his address in Pingjing?" Noriko asked.

Guan Xin tapped on the keyboard and said, "The address on his ID card has been demolished." ”

"Then the person's family can't be reached? That's weird, isn't it? People in their thirties, even if they are not married, should at least have a girlfriend. By the way, how long has he been working in Rongcheng? Qi Kai asked.

Guan Xin said: "According to a colleague of the deceased's company, the deceased only came to work in this company half a year ago, he and his colleagues were not very familiar, and the deceased had a withdrawn personality, except for the company's affairs, he hardly contacted his colleagues. So his colleagues knew almost nothing about him. ”

"I only started working half a year ago and I was a sales manager? He came to work in this company and always signed a contract, what about the contract? Shen Zezhi asked.

Guan Xin said: "I have already communicated with them, and the people from his company are sorting out the information and sending it to us." ”

Sang Yunqing said: "Preliminary."

The results of the autopsy showed that the time of death of the deceased was around 12:30 to 1:30 noon today. The cause of death was a wound in the neck, and the murder weapon was an extremely thin wire. According to the test, the main components of this metal wire are tungsten, molybdenum, chromium, vanadium and other carbides. It is a kind of steel wire with good flexibility. The murderer should have strangled the neck of the deceased with a steel wire, the hesitant steel wire was extremely thin, and all the steel wires quickly cut the skin and cut off the neck artery and trachea of the deceased. ”

Qi Kai looked at the picture of the steel wire and said: "Even if this steel is very thin and sharp, it takes a lot of strength to cut off the carotid artery and trachea in the neck of the deceased. So the murderer should be a very strong man. ”

Sang Yunqing continued: "And the physical fitness of the deceased is very good, according to our special case team, that is, Qi Kai's physical fitness is similar to that of the deceased. So if you want to strangle such a person, the murderer should at least be a man whose physical fitness is not inferior to Qi Kai. ”

Qi Kai said: "The physical fitness is similar to mine? Make no mistake, right? ”

Sang Yunqing said: "You should trust my professionalism. ”

At this time, Zhao Jiyong said: "What I am most curious about is, how did the murderer leave after killing people in the secret room?" You see, the door in the bathroom where the deceased died was fastened from the inside, and there was no sign of the window being opened. So how did the murderer get out of it after killing someone. ”

Shen Zezhi nodded: "Yes, we have to find out how the murderer got out first?" ”

Noriko smiled and said: "I remember that many cases in the cartoon "Detective Conan" are murder cases in closed rooms. ”

Shen Zezhi turned his head to look at him, and Ji Zi hurriedly raised his hands: "I'm sorry." Talk about the case, talk about the case. ”

Shen Zezhi: "This case is very strange, first, this case was directly taken over by us, which has never been done before. Second, the identity of the deceased has not yet been clarified. Third, what was the motive for the killing? It's also impossible to know for sure now. Finally, how the murderer was able to leave the body in the secret room after killing someone on the train. ”

Ji Ziyue said: "The motive for the murder in this case is indeed quite strange, Wang Liang has almost no need to murder. ”

Shen Zezhi said: "So we act separately." Mr. Zhao and Qi Kai, you mainly start from the scene of the crime to determine how the murderer completed the murder in the closed room. Ziyue, you follow me, let's start with Wang Liang himself, we must find the reason why he was killed. Yun Qing is still in charge of the corpse part. Guan Xin is in the middle. ”

"Understood!"
