After a while, there was a knock on the door, and a young man of twenty-seven or eighteen years old came in.

"Captain Yi, you're looking for me. The man named Dalong said.

"Come, come in, I'll introduce you. This is Xiao Wei, our little hero who is brave and brave in capturing gangsters today, and he is also my little brother. This is Fei Long, a technician from our brigade. Yi Qing introduced.

The young man named Fei Long pushed the glasses on his nose and nodded to say hello to Xiao Wei.

Xiao Wei also nodded and said, "Brother Fei Long is good." ”

Fei Long didn't answer, but turned to Yi Qing and said, "Captain Yi, what's the matter?"

Xiao Wei thought to himself, is it possible that the criminal police team is like this, and they don't care about people very much?

Yi Qing said: "Fei Long, my Xiao Wei brother is an important witness in the murder case of Jiang Lina. Calling you here is for you to give me a detailed account of the situation on the scene of this case, which I think may be of some help to our case. ”

Fei Long turned his head to look at Xiao Wei, and felt that Yi Qing might be too eager to solve the case, what kind of insight can this hairy boy have?

However, since Yi Qing has already said it, it is not good for him to say anything. So, Fei Long said: "Captain Yi, then please take out the pictures and photos of the scene, and I will tell you." ”

Yi Qing took out the scene pictures and photos in the file and handed them to Fei Long.

Although Fei Long was not reluctant, he still had nothing to say about his professional level, and he immediately forgot everything else when he talked about the case.

"The center site is located in a laboratory on the south side of the second floor of the laboratory building of Pengcheng No. 1 Middle School. The deceased was found lying on a table in the laboratory, on top of the laboratory table. The deceased was wearing a pink plaid dress with the skirt rolled up above the waist and the lower body naked, with panties stripped to one side of the left leg. The left leg was dressed in flesh-colored stockings, and the stockings on the right leg were taken off and thrown on the bench. ”

"There were no shoes on his feet, and there was a pair of black open-heeled half-heeled leather shoes on the ground. Because the site was not well protected and the footprints were messy, more than a dozen different footprints were extracted from the laboratory alone. There are also multiple fingerprints taken at the scene, and after comparing the fingerprints of the deceased, the original suspect Shi Mingkai and later Qian Huilai, the other fingerprints cannot be determined whose fingerprints are after comparison. ”

"In addition, a small amount of blood stains and gauze to wipe the blood stains were found on the ground on the north side of the scene, and it was confirmed that the blood type of the blood stain was type B. There was also a coin with the word 'Haoye' on it found underneath the test bench. That's pretty much what happened on the ground. ”

"Let's talk about the deceased. The deceased had marks of being slightly beaten on his face, and there were obvious pinch marks and strangulation marks on his neck. The deceased had traces of sexual assault, and the lower body wipes were extracted from a mixture of semen and liquid containing two substances, A and B, which means that the deceased was likely to be raped or have sex with two or more people. There were no items on the deceased's body, but on the laboratory table was a pink lady's satchel, which was confirmed to be the deceased's belongings. In addition to some feminine products such as lipstick, makeup cases, and tissues, four coins with the words 'Chinese and Western' were also found. That's basically what happened. These on-site investigation records are all recorded. ”

"Also, I'll also talk about the medical examiner's condition. After an autopsy, the deceased was strangled by something like a string and suffocated to death, compared with the stockings taken off from the deceased's right leg left at the scene, the stockings obviously had stretch marks, which means that the deceased should have been strangled to death by that stocking. Fei Long finished speaking in one breath, then pushed his glasses and looked at Yi Qing.

Yi Qing looked at Xiao Wei and said, "The scene is over, Xiaowei, let's talk about it." ”

Xiao Wei thought for a while and said, "I haven't thought about anything else, but I think there is a problem with these game coins." ”

Yi Qing asked, "These should all be coins that the deceased Jiang Lina carried." Oh, it's game currency, which can only show that the deceased liked to play games very much, which doesn't seem to have anything directly related to the case. ”

Xiao Wei said: "That's right. I think there are a few doubts in this: Ichijiang Lina's satchel contains four game coins, but the satchel is not open, so there is little chance of falling out of the bag. The second is that you may not have noticed that the game currency under the test bench is obviously different from the game currency in the bag. ”

"The game currency in the bag has the words 'Zhongxi' on it, and the game currency that fell under the laboratory table has the word 'Haoye'. ”

At this time, Fei Long interjected: "I also noticed this, it is different. But it's all in-game currency, so what does it mean?"

Xiao Wei continued: "If you don't play games, there may be a situation that you don't know. This kind of in-game currency is only used on arcade consoles, not on other TV games. As far as I know, there are only two game halls in Pengcheng that have this kind of arcade, and they use this kind of game currency with the words 'Chinese and Western', of course, there are other words, but they are also game coins for playing games. ”

"What I'm going to say is the kind of game currency with the word 'Haoye', although it is also a game currency, but it is different from the 'Chinese and Western', it is not the game currency for playing ordinary game machines, it is a game currency specifically for 'slot machines'. As far as I know, there is no slot machine in Pengcheng now, even in Anzhou City, there is only one, that is, in the game hall on the top floor of the 'New Era' shopping mall. So I analyzed that this game currency is probably not Jiang Lina's. ”

"Isn't it possible for Jiang Lina to go to the game hall in Anzhou City to play?" Fei Long said.

Xiao Wei explained: "You may not have been to the 'New Era' game hall, and probably you haven't played 'slot machines'. There are very few girls like Jiang Lina who go there to play, and besides, the slot machine is a kind of gambling machine, which is not something that a student like Jiang Lina can afford.

Yi Qing listened for a long time, and then answered: "What you said may be reasonable, we are really not familiar with this, so we may have ignored it." Do you think the owner of this in-game currency is someone else?"

Xiao Wei said: "Yes, I just think that this game currency is very likely not Jiang Lina's, so since it is not Jiang Lina, it must be someone else." In other words, is it possible that someone was there at the time of the crime?"

Yi Qing's expression became serious: "Then according to what you say, then this case will be even more complicated." After the money will come to the case, no matter how much you ask, you will not admit to committing the crime, then it is probably not a matter of attitude. ”

Fei Long on the side interjected: "Speaking of which, since I already feel that the case is suspicious, then I still have a situation where I think it is necessary to talk about it." ”

"Oh," Yi Qing looked at Fei Long in confusion: "Then you say." ”

Fei Long said: "In fact, when I was investigating the scene, I had already noticed that when I was investigating the footprints at the scene, I also found the footprints of the deceased Jiang Lina behind the door of the laboratory. I thought it was strange at the time, the location behind this door is generally not visited, and it is relatively far away from the center site, so what is she doing by herself. It's a bit counterintuitive. ”

"At that time, I also told the situation to Captain Wang Weidong, the captain of the serious crime team at the time. As a result, it didn't take long for Captain Wang to arrest the murderer Shi Mingkai, and Shi Mingkai also confessed, the case was solved, and there was no need to say this situation, so I just recorded it in a notebook and did not write it in the scene investigation record. ”

Yi Qing was a little anxious when he heard this, and said, "Why didn't this situation be written in the on-site investigation record? And Shi Mingkai didn't say that there was such a plot." ”

Fei Long explained: "At that time, the case was quickly solved, so all the evidence was collected around Shi Mingkai, and useless situations had to be excluded, which was also what Captain Wang meant, mainly for the convenience of litigation in the future." ”

Yi Qing stopped talking, he understood that this was indeed a common practice.

In those days, the confession of the suspect was important and was known as the king of evidence. When a case is solved and the main suspect confesses, basically all the evidence collection and evidence collection work revolves around the confession of the suspect, and other details that may not be consistent with the confession and the scene will be artificially removed. This is both for the smooth running of the litigation and for the reduction of unnecessary workload.

After all, sometimes it takes a lot of energy to rely on evidence to eliminate this detail, which is also a helpless choice in the case of a serious shortage of police force.

Thinking of this, Yi Qing waved his hand and said, "Okay, let's not talk about this situation for now, let's talk about the case." If the situation Xiao Wei said really exists, then can we imagine what happened in this way? ”

On the day of the incident, Shi Mingkai and Jiang Lina went on a date in the experimental building, and when the two finished making out and had not yet left, Qian would come and secretly go to the experimental building to get something. Shi Mingkai and Jiang Lina heard Qian Huilai's footsteps or other sounds, and knew that someone was coming. Shi Mingkai didn't dare to let people know that he was cheating with a female student, so in a hurry, he jumped out of the window on the second floor of the laboratory and escaped. ”

After Shi Mingkai jumped out of the window and escaped, Jiang Lina didn't dare or couldn't jump out of the window, so she could only find a dark place at the door to hide, which explains why there were Jiang Lina's footprints in the position behind the door of the laboratory. The money that came in didn't find Jiang Lina, she took the alcohol directly in the laboratory and left, and she accidentally broke her hand in the process of taking things, so there will be blood stains from Qian Huilai and gauze to wipe the blood stains at the scene. ”

"After the money meeting came and left, Jiang Lina was also ready to leave, and at this time, another man, let's call it a 'third person', entered the laboratory. This time, this 'third person' found Jiang Lina who was hiding, and he became interested in trying to have a relationship with Jiang Lina, but Jiang Lina should have resisted, and the 'third person' also beat Jiang Lina, and finally used violent means to rape Jiang Lina. ”

"This 'third person' should have choked Jiang Lina's neck when he committed the crime, but he didn't strangle him to death. Later, in order to cover up the crime, or for some other reason, they killed people. After strangling Jiang Lina with the stockings she was wearing on her right leg, he threw them away and fled the scene. This should be what happened to the case. What do you think?"

After listening to Yi Qing's analysis and deduction, Xiao Wei and Fei Long felt that it was very exciting and logical, and they couldn't help but admire Yi Qing's rigorous logical thinking and inference.

"However," Yi Qing changed his words: "All the inferences just now are based on the fact that this 'third party' does exist. But now it is indeed a bit reluctant to judge the existence of such a 'third party' based on this game currency alone, because it is completely possible to put the crime plot of this 'third party' on Qian Huilai. Therefore, in order to prove that inference is correct, it is necessary to find this 'third party'. ”

Yes, but it's not easy to find such a 'third party'. Who is this man?

Yi Qing, Xiao Wei and Fei Long all fell into deep thought......
