At 6:23 p.m., the conference room of the Third Criminal Police Squadron of the Yandong Public Security Bureau was filled with smoke.

After a day of investigation, I had no clue, and the leaders and criminal police officers who participated in the second case analysis meeting looked solemn. Xi Da looked back at Deputy Captain He of the Criminal Police Detachment who came to guide the investigation, and lit a cigarette.

Lin Xiaopeng, the leader of the technical squadron who inspected the scene last night and led the team to the scene again this morning, peeked at the two leaders, held a small notebook and continued: "After another investigation, it can be determined that many people committed the crime, and it was a planned and premeditated crime. After entering the house, they controlled both adults and children, and took the adults to the left room on the first floor, where they were better insulated and tortured.

The female victim had 24 bruises, 4 abrasions, a blow to her face, 3 broken ribs, and was brutally tortured before her death. It stands to reason that the murderer should have left many traces, but the scene was very clean, no fingerprints were extracted, and no footprints were found. Fortunately, the victim resisted and bit the murderer, which allowed us to extract the DNA of one of the suspects from the female victim's mouth. ”

"So the living room is not the first scene. ”

"No, the left bedroom is. ”

Lin Xiaopeng handed over a stack of photos, turned around and walked to the white blackboard, and pointed to the topographic map drawn with a pen: "We found many bloodstains here, here, and here, and there are more bloodstains from here to the living room, and it can be seen from the distribution of bloodstains that the victim was dragged to the living room. ”

"How did the murderer clean up the scene?" asked Deputy Detachment Leader He.

"We found large blood stains in the washbasin, toilet and shower room, but we didn't find anything like a mop or rag, and the murderer should have taken those things away after cleaning up and disguising the scene. ”

"Did you look near the scene of the crime?"

"I searched, but there were no garbage bins or dead corners nearby, and no blood stains were found. ”

Throwing it far away shows that the murderer has a certain sense of anti-investigation, and it can be seen that the murderer is very cunning.

Xi Hongbo looked at the photo again, looked up and said, "What about the child?"

"The strangulation was not so painful compared to the female victim, at least she didn't suffer too much. ”

"There will be no mistake in judging the time period of death. ”

"No, Director Liu personally went to the scene and personally participated in the autopsy, and Director Liu also believes that the time of death of Zhang Qiuyan's mother and son should be between 7 pm and 10:30 pm on the 15th. ”

The judgment made by the director of the forensic examination and identification center of the Municipal Bureau should not be wrong, Xi Hongbo nodded slightly, and while motioning for him to sit down, he said coldly: "Comrades, the technical department has done a lot of work, found many clues, and even mastered the DNA of one of the suspects, and then we will look at the investigation." Xu Wei, you come first, tell me your opinion. ”

"Xi Da, I would like to ask Xiaopeng first, has the DNA extracted from the mouth of the female deceased been taken to the DNA database of the Ministry of Public Security for comparison?"

What a problem!

Xi Hongbo was embarrassed by him, and asked rhetorically, "What do you say?"

Xu Wei, the leader of the serious case squadron, reacted and hurriedly said, "Xi Da, I'm just asking." In terms of opinions, I think there are many doubts in this case that must be investigated. First of all, we ran for a day, visited more than 40 relatives of Qiao Zhang's family, visited five decoration companies where Qiao Xianhong worked, more than 20 plumbers, carpenters, bricklayers, painters who worked together, and even visited some decoration material suppliers that he frequented.

As a result, everyone knows that he has lost money for decoration and owes a lot of debt, but he doesn't know how to pay for it, what kind of decoration project to pay for, who he owes and how much money he owes. Some of the things that Qiao Xianhong said before his mysterious disappearance, some of them were said by Zhang Qiuyan, and some of them were spread like this. ”

There must always be a creditor in debt, Deputy Detachment Leader He felt that this was a major suspicion, and asked in a low voice: "Has he ever borrowed money from relatives and friends?"

"No, so Qiao Xianhong is very suspicious, this suspicion does not mean that he is suspected of murder, but that he is suspicious on the issue of owing money and hiding debts. Since you owe a fart debt, you must find a way to pay it back. As a result, no creditor came to ask for it, and he didn't care about his relatives and friends borrowing money to solve his urgent needs. ”

After so many years as a criminal policeman, this situation is really the first time I have encountered it.

Deputy Detachment Leader He groaned: "Maybe he really owes a lot of debt, but it is not owed for decoration, and the debt he owes far exceeds his ability to repay, even if he borrows from relatives and friends, he can't pay it back, so he simply leaves." If this is the case, then the murderer of Zhang Qiuyan's mother and son is likely to be the creditor. ”

"Report to He Zhi, after we found these suspicions, we immediately thought of whether Qiao Xianhong could be involved in gambling or drugs, but from the information learned from the visit and inquiry, Qiao Xianhong is a person with almost no bad habits. Maybe because his father died early, and the family was more difficult before, so he was very hardworking, capable and willing to work.

No one has ever seen him play cards, and his relatives get together during the New Year's holidays, and he doesn't play with him, he doesn't smoke or drink, and he is very frugal, and people like him are unlikely to be involved in gambling, let alone drugs. From this point of view, it can also be seen that a cautious person like him cannot lose money when engaging in decoration, but it is just a matter of earning more and earning less, and he can't owe huge debts because of decoration. ”

……

Qiao Xianhong is missing, Zhang Qiuyan is dead, Qiao Xianhong's mother Wang Qiaolan has already remarried, what is the situation in this family, I can't find an insider!

The leaders studied and analyzed in front, and Wu Wei sat in the last row racking his brains and meditating.

It wasn't until his master Liang Dongsheng stood up to report that he regained his senses and hurriedly sat up straight.

"Report to He Zhi, report to Xi Da, our group visited and questioned 214 residents of Yangguan Village, although many villagers were enjoying the shade on the street on the night of the incident, because there were too many outsiders renting in the village, the villagers did not find anything abnormal. Considering that the outsiders who rent in the village will either go to work, go out to work, or go out to do business during the day, we Liu Law Firm decided to organize forces to conduct a comprehensive and thorough inventory of the outsiders who rent in Yangguan Village at 10 o'clock tonight to see if we can gain anything from the inventory. ”

There are too many people, which is a big headache!

The traffic, public security and civil surveillance video around Yangguan Village can be extracted, and dozens of people are guarding the computer in the substation to repeatedly analyze and judge the video, but there are too many people and too many cars in the video, and everyone is suspicious.

There is a license plate number, and the car can be checked.

It is impossible to write the ID number on the face, only the physical features, and the facial features taken at night are not very clear, and there are thousands of people, how to "sit in the right number" one by one, how to find out their identity.

So in this case, the dumbest way is often the best way.

Xi Hongbo felt that the evening investigation was very necessary, and raised his head and asked, "Is the police force enough?"

"It's definitely not enough, but Liu will find a way, it's a big deal to find out until dawn. ”

"Tell Liu Jianye that the police force is not enough, and I will help you solve it. At 10 o'clock, I asked the police who assisted you in the investigation to gather at the police station at 9:30. ”

"Thank you, Xi Da, I'll call Liu Suo. ”

"Go ahead. ”

"Yes!"

"Du Xiaolian, you are responsible for checking the mobile phone call records of Qiao Xianhong and Zhang Qiuyan, and immediately prepare the formalities; Du Shaohua, you are responsible for investigating the real economic situation of Qiao Xianhong and Zhang Qiuyan, I will call the economic investigation brigade and ask them to arrange two economic investigation policemen to assist you, immediately prepare the procedures, and send them to the sub-bureau with Xiao Du to find the Zhou Bureau to sign. ”

"Xu Wei, Qiao Xianhong's situation, especially social relations, should be investigated deeply, and you will continue to be responsible for this line. The action should be fast, the work should be meticulous, and no clues should be missed. ”

"Yes!"

……

The leader kept giving orders, but none of these orders were related to him.

As soon as he heard that he was going to be transferred to the special case team, Wu Wei didn't know how excited he was, after all, not every police officer had the opportunity to participate in the investigation of major cases, but he still did the same job when he joined the special case team, visiting and inquiring in Yangguan Village with the criminal police during the day, and returning to Yangguan Village to participate in the investigation operation at night.

Wu Wei was really a little disappointed, followed Liang Dongsheng out of the conference room, and couldn't help but ask as soon as he got into the police car: "Master, the people in the village don't know outsiders, and the outsiders don't know the villagers, at most they know their respective landlords, even if someone has seen the murderer, they don't necessarily feel suspicious.

"If this murder doesn't happen, we won't check the foreign population in Yangguan Village?"

Liang Dongsheng asked rhetorically, fastened his seat belt, closed his eyes, yawned and said: "How do you think the case was solved, Sherlock Holmes, that's a movie! And the case is based on evidence, even if anyone knows that so-and-so is the murderer, the case is not solved without evidence." Therefore, it is necessary to coordinate with multiple police departments and fight in large corps, every task is very important, and everyone is indispensable. ”

"But ......"

"Don't be, I know what you think, in fact, our case-handling team turned out to be the criminal police team, and you Wu Wei are the criminal police. It's just that in the past few years, police reform has been carried out, and it has been changed back and forth, and both criminal and public security cases have to be managed. ”

Liang Dongsheng moved his buttocks, adjusted to the most comfortable position, and continued: "You and Han Chaoyang are assigned to the institute together, the leader likes you, but he doesn't like Han Chaoyang, but that kid does something every once in a while, which is really a bit of pressure on you, but people are more popular than people, many things can't be compared, and his ability to always be in the limelight doesn't mean that he is better than you, and his mentality must be better, you know." ”
