In the blink of an eye, a week has passed.

The video team of 8 people, after more than 30,000 hours of surveillance, only saw the whereabouts of the suspect in a remote camera for 1 second.

Li Xiang found the severed finger at 9:40 p.m. on the 11th, and the time of video surveillance was found by Li Xiang at 2:20 a.m. on April 10, that is, the day after the body was dumped.

In the surveillance, the night twilight is shrouded, the stars and the moon are shining, a hazy shadow, riding an electric car, flashes in the video screen, although the total duration is only 1 second, but the black object on the pedal of the electric car is very similar to the woven bag they salvaged from the river and used to hold the corpse.

This coincides with the means of transportation speculated by the police, and the body size of the person riding the electric car is also similar to the body size of the suspect analyzed by the police, but because of the sky, the video is very blurry, and it is difficult to find the suspect according to this.

According to the 1-second picture in the video, the police also analyzed his general course of action, further expanded the scope of the investigation, and continued to investigate in his possible routes.

The first thing Zhou Yan does when she comes to work every day is to continue to compare the DNA data of the deceased to prevent the deceased's family from being unable to compare in time after the family reports the case.

On this day, when she compared the missing person again, the system suddenly prompted that the comparison was successful, and a missing person information was compared.

"Quick, come and see, the dead are on the right track."

Zhou Yan happily called everyone over, only to see that this data was uploaded to the missing person database at 4 o'clock in the afternoon yesterday, which happened to be the missing person report received by the Hongqiao Police Station, and the report time was April 11, and the informant was a mother and daughter.

After the police station filed the case according to the process, the DNA of the families of the missing persons was collected, and it was uploaded to the database of the missing persons yesterday, and it was compared by Zhou Yan early this morning.

"Great, bring up the identity information of the deceased."

The DNA comparison was successful, which made everyone in the first squadron a lot excited, after all, the video surveillance did not find more information about the murderer, and the investigation of the case was at an impasse for a while.

At this critical time, the DNA comparison was successful, which made a big step forward in the detection of the case.

"The deceased Hao Lianshan, 45 years old this year, a local, his parents have passed away, his family lives at No. 114 Fuyang Road, and the household registration of the public security system shows that this person is divorced, has a daughter with her mother, and the person who reported the case is his daughter and ex-wife."

Zhou Yan quickly called up the victim's identity information, and Cao Gang immediately ordered: "Mao Ji, Li Xiang, you go to the scene to find the deceased's ex-wife and daughter to understand the situation, and I will take the technical team to the deceased's home to investigate." ”

After having the latest clues, everyone's passion was also tuned.

After Li Xiang and Mao Ji received the field task, they immediately found the police record, found the contact information of the deceased's ex-wife from it, and made an appointment for a routine door-to-door inquiry.

The deceased's wife, Mu Xingjuan, is 41 years old and runs a clothing store.

Li thought that when they came to the store, they saw that she was receiving customers, so they didn't come forward, and waited until she sent the customers away, and then went in.

"Hello, we are from the Public Security Bureau, we just had a phone call, about your ex-husband, we still need to find out about some situations."

Because of the reason that she opened a clothing store, Mu Xingjuan is also more fashionable, with makeup painted on her face, and she looks like a woman in her thirties.

"Comrade policeman, is Hao Lianshan really dead?" Mu Xingjuan's expression looked a little sad.

"Yes, do you know if he usually has a feud with anyone?"

"We have been divorced for three or four years, and he usually lives alone, and I don't know much about his situation."

"In that case, how did you know about his disappearance?"

"Although I don't have much contact with him, but my daughter has a lot of contact with him, and I have to contact him every once in a while, and that day she said that my father couldn't be contacted, so I went to his house to take a look, and the things at home are all there, and they are all very neat, but the person is gone, and I asked a friend, and I don't know where he went, so we went to the police station to report the case."

"What did he do before?"

"He used to help people install air conditioners, punch holes, and clean range hoods, anyway, he didn't have any legitimate occupation, so he relied on odd jobs, and if he wanted to make a feud, there was nothing to make a grudge."

Hearing this, Li Xiang frowned a little, since it is not a vendetta, it should not be a financial killing, after all, how much money can a person who does odd jobs have? And the house is clean, and there is no burglary and murder, is it love killing?

Since ancient times, adultery has led to death, and in all homicide cases, adultery has led the way.

So Li wanted to guess that it might be a homicide case caused by adultery, so he asked: "Then after your divorce, has he found a partner over the years?" ”

"I don't know that, you're going to ask him, uh, I didn't mean that."

Mu Xingjuan's temper was a little hot, and this sentence was obviously angry, but after finishing speaking, when he thought that Hao Lianshan was dead, let the police comrades go to him, wasn't it cursing them, so he touched his head embarrassedly.

Li thought they were a little speechless, is this girl Biao?

Isn't it brain-talking?

Here, Li Xiang and they were still making notes for Mu Xingjuan, and Cao Gang took technicians and rushed to Hao Lianshan's place.

As Mu Xingjuan said, Hao Lianshan's home is very clean, not like a murder scene, after the technicians surveyed the scene, there was no trace of a struggle at the scene, let alone a murder scene, and the victim should have left by himself.

Then he notified the traffic department and called up the video surveillance at the intersection to take a look.

In the video, Cao Gang's conjecture was also verified, the deceased rode an electric car at 8 o'clock in the morning on April 8, and the electric car he rode was highly consistent with the electric car that the murderer was riding in the police surveillance video at 2:20 a.m. on April 10.

"Continue to follow his whereabouts."

The murderer's trajectory was not tracked, but Hao Lianshan walked on the main road, and his whereabouts were still very easy to track.

While instructing the police officers of the video surveillance team to hurry up and eliminate it, Cao Gang sent someone to the communications company to retrieve Hao Lianshan's communication records to see who he ended up talking to.

As the case progressed, more and more clues were gathered to Cao Gang like snowflakes, but the difficulty of solving the case exceeded his original estimate.

The murderer was obviously premeditated, and he took every step into account.

Hao Lianshan's last appearance was on Jiang'an Road, and then he lost his target, and when he reappeared, it was at 2:20 a.m. on April 10, when he was broken into pieces and put into a bag to throw his body into a stinking ditch.

"The last place where Hao Lianshan appeared was on Jiang'an Road, and the place where the murderer appeared was also in this range, so a certain place here must be the scene of the first crime."

Cao Gang drew a circle with a red pen on the map in his hand, and the first scene of the murderer's crime must have been in this circle.

Now it is to continue to send more manpower to conduct a carpet search in this area, and through a large number of visits, someone should find out Hao Lianshan's last whereabouts.

After Li Xiang and Mao Ji finished their inquiry about Mu Xingjuan, they found some friends and co-workers of Hao Lianshan, and everyone spoke highly of him, saying that he was an honest and responsible person, never made enemies with others, and sometimes would rather suffer a small loss than blush, and it was unlikely to be a vendetta, which also confirmed Li Xiang's guess.

But it's not a vendetta killing, it's not a financial killing, and there's no love killing, so what's the reason?

What exactly was the murderer's motive for killing?

The time of the day passed quickly in the midst of everyone's intense investigation.

The next day, as is customary, all the people of the first squadron got together again for a regular meeting, and everyone touched all the clues in their hands.

"Mao Ji, how is the situation of your investigation yesterday, tell you."

Mao Ji took out his workbook, and he recorded the situation of yesterday's investigation and some suspicious speculations in a notebook and put it at the meeting for discussion:

"Yesterday Li Xiang and I visited the deceased's wife Mu Xingjuan, his daughter Hao Jia and some of his friends, Mu Xingjuan and the deceased divorced after the daughter's college entrance examination, it has been three years, during which the daughter was with her mother, but during her college years, the interaction with his father was quite frequent, Hao Jia also wanted them to remarry, but Mu Xingjuan has not agreed, this time the daughter has not contacted the deceased for a long time, only to find out that he is missing, otherwise, no one will call the police for him."

At this time, everyone was afraid for a while, if Li Xiang didn't take a walk with briquettes, he wouldn't have found the amputated finger; If Hao Lianshan had cut off contact with his daughter after the divorce and did not call the police in time, I am afraid that he would have disappeared from this world after he died.

Fortunately, there is no if, in the dark, there is a destiny, and Hao Lianshan's death should not disappear out of thin air.

"Through the visit and investigation, the deceased was honest and duty-free, never made enemies with others, it is unlikely to be a vendetta, he has been doing odd jobs, and he is not very wired, his wife dislikes divorce, and it is not very like a financial killing, and it is unlikely that a love kill is unlikely, there is no money and no face, and there should be no woman who likes it, so the motive for the crime is still uncertain."

"Is it random killing?"

After listening to Mao Ji's analysis, Zhou Yan also raised questions, not vendetta, not financial killing, not love killing, so what else?

The biggest possibility, and the last thing the police want to see, is a random killing.

But this speculation was quickly rejected by the Cao team: "This is by no means a random killing, but a premeditated murder, whether the murderer chooses the crime scene and the place where the body is thrown, it is carefully calculated, and most of the public cameras are deliberately avoided, not only that, we retrieved the deceased's communication records, his last communication contact, named Wang Yuanli, but when our police found him, he said that he did not know Hao Lianshan, and he did not call him, during that time, his mobile phone was lost." ”

Team Cao took out the map that was circled yesterday and sandwiched it on the blackboard, and a red circle circled it was the first scene where the murderer's body might be divided.

"Hey~ This murderer is too cautious, right?"

After listening to Team Cao's words, everyone gasped, and suddenly felt that this murderer's mind was too meticulous.

Every step is being carried out according to his plan, looking at this, the opponent of the police this time is probably not simple.

If it weren't for the discovery of the severed finger, Hao Lianshan would probably have died in vain.

No one even knew whether he was alive or dead.

"At present, continue to strengthen the investigation in this area, and if you have any ideas, or useful suggestions for the detection of the case, you can put forward them and discuss them together."

After Li Xiang looked at the circles on the map, he thought that when he found the severed fingers, the minced meat was basically bloodless, just like the pork bought at the meat stall in the vegetable market, and when the murderer threw the body, the woven bag was already broken, and there was no blood on the ground, which immediately made Li think of a possibility: Where did the blood of the deceased go?

With grandmaster-level experience in forensic science, he knows very well that a person who weighs 65kg has about 5000cc of blood on his body, where does so much blood end up?

It must have been the scene of the dismemberment.

In order to treat the site, a large amount of tap water is used.

Thinking of this, Li Xiang raised his hand and put forward his opinion: "Since the murderer is dismembering the corpse in this range, if the corpse is divided at home, then the murderer will definitely be cleaned, and it is inevitable that on that day, the water consumption at home will soar." ”

"Yes, you can think of this step, it's already very good, I have arranged for someone to go to the water company to investigate the water situation in this area, I believe there will be results soon."

Cao Gang, as the captain of the criminal investigation team, naturally thought of this a long time ago, but Li Xiang, as a criminal policeman who left home halfway, was able to react so quickly and knew the details of paying attention to the water consumption of residents, which is very good, proving that he is also a person who pays attention to details.

Although he only drew a small circle on the map, there are more than 3,000 households in this range, and it will take a lot of time to check them one by one, but fortunately, these can ask the staff of the water company to check the water consumption of the water meter.

"It's still the Cao team that has a lot of experience." Li Xiang scratched his head, he didn't expect his suggestion, Team Cao had already arranged for someone to investigate, or else, he was the captain.

"So, back to the point, what is the murderer's motive for killing?"

The determination of the motive for the murder can also point out the direction of the investigation for the police, and there is no need to be like a headless fly, flying around without a clue.

Faced with this question, everyone looked at each other, not knowing what to answer.

"Since ancient times, adultery has led to murder, will it be adultery? Such a premeditated murder, not like a crime of passion, the murderer should have been prepared for a long time, judging from the analysis of the timeline, the deceased went out on the morning of the 8th, and should have been killed since then, the murderer went to throw the body on the night of the 10th, if the murderer is only one person, it takes two days to complete the dismemberment, and he must have prepared very thoughtful tools for the crime, otherwise it is not so easy. ”
