In less than 70 days, four criminal cases occurred one after another, not to mention Yang Wenjing, the daughter of the deputy mayor in charge of politics and law and the president of the civil division of the court, and Yang Yutang, the chairman of the Dousheng Group, who is worth billions, and his wife Wei Dongdong, whose special identities are, just four lives are enough to cause a sensation and make the entire Jiangjun City panic.

Therefore, as soon as he received a call from Xun Jianguo, Ling Zhan, who had just been promoted to deputy director in charge of criminal investigation for only half a month, immediately handed over the work of investigating and screening the 21 suspicious persons whose household registration was not in the urban area from the antique files built by Zhou Wei before his death to the two criminal policemen who accompanied him, and he drove back to the urban area quickly, and did not return to the serious crime team but rushed directly to the scene of the crime.

"Uncle Xun?"

Xun Jianguo raised his head from the bloody footprints in front of him and said, "Judging from this strange barefoot bloody footprint, the suspect should be a man." The footprints are 25 centimeters long, and according to the rule of "standing seven and sitting on five plates and three", it is speculated that the suspect should be about 1.75 meters tall. Moderately built, weighing between sixty-five and seventy kilograms.

The traces left by the middle toe of the five toes of the bloody footprints are the clearest, indicating that the suspect is about 40 years old. ”

The common sense of inferring a person's age based on the characteristics of barefoot footprints, Ling Zhan also knows a little bit.

Because the human calf muscles, that is, the tendon tissues that play a role in manipulating during walking, will change accordingly with age. Normally, the calf muscles are most powerful before the age of 20, so the focus of the toe will be on the female toe. Around the age of 30, it will move to the second toe, and so on, around the age of 40 in the fourth toe, and after the age of 50, the little toe will be more forceful.

If you are careful in life, young people's shoes will usually be the first to break from the big toe to the third toe. After the age of 50, it is often the outer edge of the little toe that is worn first.

Hearing Xun Jianguo's analysis, Ling Zhan nodded and asked, "Uncle Xun, is there anything else suspicious?"

"From the fact that the doors and windows of the room are intact, the suspect should have entered the room through the door. According to the preliminary inference of the medical examiner, the time of the victim's death was between 1 and 3 a.m. Due to the eccentric personality of the victim, it should not be possible for the victim to commit the crime by an acquaintance who stayed overnight. In other words, the suspect opened the door with a key.

In addition, the suspect was not found at the scene with the murder weapon, which should have been taken away after committing the crime. ”

Looking at the strange barefoot footprints in the bedroom door, Ling Zhan thought for a while and asked tentatively, "Could Lu Qingyuan's killing be related to our investigation?"

Just started to find out the ranks, and Lu Qingyuan, who was on the list of thirty-four people, died in his own home, which couldn't help but make Ling Zhan suspicious.

"This possibility cannot be ruled out. In particular, from the scene inquest, it was found that the suspect had traces of rummaging through the victim's home. However, Lu Qingyuan's wallet, mobile phone, and the 2,000 yuan in cash in the drawer of his bedside table were not missing, and all signs indicated that it was more like the suspect was looking for something. ”

"Can you be sure what it is?"

"No, you can't. Lu Qingyuan's behavior is quite eccentric, not only does he have no close relatives around him, but he doesn't even have a friend he can talk to. There is no way to know what exactly is stored in his home that is worthy of the suspect's covetability. ”

This is indeed a difficult problem, on the premise of not knowing what Lu Qingyuan has in his house, how to determine what the suspect wants to rummag through?

The only hope for solving this puzzle is to solve the case and catch the suspect as soon as possible.

At this point, Ling Zhan had to temporarily decide to gather Rong Liang, Zhao Zengyuan, Qi Zhibin, and Song Jin, and order them to hand over the work at hand to the criminal police team or the district dispatch, except for Jia Wei and Xiao Hua, who were on a business trip, the serious crime team went all out to solve the case of Lu Qingyuan's murder.

After returning to the office of the serious crime team with Xun Jianguo, Rong Liang and the other four people who received the order had already arrived.

First of all, Xun Jianguo gave a detailed introduction to what he knew about Lu Qingyuan's personality and temperament, as well as the situation found at the crime scene, and emphasized the physical characteristics of the suspect derived from the analysis of the strange bloody footprints.

Finally, he said: "Although the possibility of an acquaintance committing the crime cannot be ruled out, it is unlikely based on the usual behavior of the victim. As for the suspect's motive for committing the crime, it is difficult to draw a conclusion for the time being. What can be basically ruled out is love killing, and the victim is a person who doesn't like to come into contact with people, so the possibility of vendetta is not very likely. ”

Immediately afterwards, Ling Zhan assigned the task and said: "Rong Liang and Zeng Yuan try to learn as much as possible from the neighbors and acquaintances of the victim Lu Qingyuan whether he has any special habits in his life, or whether he has a special hobby for any items. Try to find clues about what the suspect wants from Lu Qingyuan.

Also, try to see if you can find out who has access to the key to the victim's door.

Xiao Qi investigates the people in the urban area who have technical lockpicking skills, regardless of whether they have a criminal record or not, as long as they are between the ages of 35 and 45, they will all be investigated, and no one can be spared.

Song Jin is responsible for investigating the victim's mobile phone call records, as well as all the bank accounts under his name and the inflow and outflow of funds.

Uncle Xun ....... ”

Interrupting Ling Zhan's words, Xun Jianguo took the initiative to say, "I'll go to the video group." ”

Of course, Ling Zhan will not be idle, he has more important things to do, one is to report to Director Ma Jinzhong, and the other is to deal with the next media reporters, so as to take the opportunity to appease the panicked citizens.

Last time, he originally gave Qi Zhibin the task of dealing with the reporters who were worried about hearing the news because of Xing Zhongdian's sudden disappearance, and he didn't want to wait until now, and the imaginary scene did not happen. Although Ling Zhan and the others were a little puzzled, no one had the time and energy to analyze what caused it.

did not hand over this task to Qi Zhibin again, because the impact of this murder case was too great, and it was no longer appropriate to arrange for the young Qi Zhibin to come forward, so Ling Zhan decided to go out himself.

As soon as I walked into Director Ma Jinzhong's office, I saw that the other party was answering the phone.

"Yes, Vice Mayor Yang can rest assured that the city bureau will go all out to solve the case as soon as possible and give an explanation to the general public...... Yes, yes. ”

Putting down the phone, Director Ma Jinzhong looked at Ling Zhan who was standing in front of him, and said in a solemn tone: "I heard it, Vice Mayor Yang's call." ”

"I just came back and went to the site to check it out. All members of the Serious Crime Team have also been ordered to pounce. ”

"Sit down. "There is no need for Director Ma Jinzhong to contact him, political commissar Sun Qunli has already pushed the door and walked in.

In front of the two of them, Ling Zhan told Lu Qingyuan about the murder case from beginning to end. Finally, he concluded: "In my personal opinion, the sudden murder of Lu Qingyuan is very likely to be related to the murder of Yang Wenjing and Yang Yutang that we are investigating. ”

"Do you suspect that the suspect is looking for an antique from the antique file of Zhou Wei, an antique dealer who died in a car accident?"

"Yes. ”

"Evidence?"

"Not yet. ”

"The key question now is how to deal with the influx of journalists, and how to reassure the panicked general public. Political Commissar Sun Qunli changed the topic and said: "If Deputy Director Ling is busy investigating the case, I can take on this task, but what should I say to reporters?"

understood what political commissar Sun Qunli meant, he wanted a clear deadline for solving the case. Knowing that he and the serious crime team had no way out, Ling Shizhi pondered and said decisively: "I promise to solve the case within twenty days." ”
