"After identification by the policeman handling the case at the time, he determined that the photo restored in our co-investigation notice was that of the masseuse, Zhou Lin. In addition to Zhou Lin, there have been about three reports of missing women in Huangxu City in recent years. You can’t see people alive, and you can’t see corpses even if you are dead.”

For everyone who had no clue, this news was like a ray of light in the fog, and everyone became excited instantly.

Zhao Donglai said even more excitedly, "Immediately contact the police over there and ask them to send Zhou Lin's detailed information, as well as all the police records and interview records when she disappeared."

"In addition, let them notify the family members of these missing women to take time to come to our place for a DNA test."

The faces of these corpses have been unrecognizable, and DNA identification technology can only be used to determine whether they belong to these missing persons.

Soon, all Zhou Lin's information was sent over.

Zhou Lin, female, 25 years old, from Huangxu City, Anyuan Province, is married and has a son and a daughter with her husband.

Her husband, Xu Yuan, works as a tower crane on a construction site, while Zhou Lin works as a technician at a foot massage club, and her parents-in-law take care of their two children.

Because raising two children is quite stressful, the couple usually work very hard, especially Zhou Lin. In order to earn commission from more customers, she usually works until two or three in the morning before getting off work.

On the morning of March 3 this year, after her mother-in-law sent her two children to school, she found that the food left on the dining table had not been touched.

Because Zhou Lin usually got up in the morning, finished her meal, and then went back to catch up on her sleep. The old man thought she had overslept, so he planned to wake her up and finish her meal before going to bed.

As a result, no one answered the knock on the door. After pushing the door open, he discovered that she had not come back at all last night.

Although there is a staff dormitory where Zhou Lin works, Zhou Lin has never lived there. She usually goes home to rest no matter how late she works.

So her mother-in-law thought it was a little strange. She wanted to call her to ask but she kept saying that the phone was turned off, so she called her son.

Xu Yuan's construction site is far from home, so he usually lives on the construction site.

After receiving the call from his mother, he didn't take it seriously at first. He just called a colleague of Zhou Lin who was better at playing, but the other party told him that Zhou Lin went home from get off work around one o'clock last night.

Only then did Xu Yuan realize that something was wrong, and immediately rushed back to call the police.

The police then conducted a careful investigation of the route Zhou Lin took to work and home, and also retrieved surveillance videos along the way. They found that after Zhou Lin passed a traffic light intersection, there was no more of her at the next intersection. figure.

At that time, the police concluded that she should have been abducted between these two intersections.

But the police searched that section of the road and found no useful clues.

The case is pending.

"So, what do you think after reading this transcript?"

In the office, Zhao Donglai stared at Luo Fei expectantly.

"As a single woman, returning home late at night, there are too many possibilities of being kidnapped. The murderer can be impromptu or premeditated, and it is difficult to tell whether it is an acquaintance or a stranger."

Luo Fei analyzed it to himself, and then said, "Captain Zhao, can you show us the records of Zhou Lin's family at that time?"

Zhao Donglai immediately clicked on another document, which contained the transcripts and photos of Zhou Lin's family and colleagues sent by the police over there.

The first one belonged to Zhou Lin's husband Xu Yuan.

Zhou Lin disappeared at that time, and the police also suspected whether an acquaintance committed the crime in revenge, and there were also related questions in the transcript.

But Xu Yuan's answer denied the police's speculation.

He said that his wife Zhou Lin has a gentle and easy-going personality and rarely gets grudges with others. She is even less likely to have any enemies in her daily life, so there should be no such situation.

Other relatives of Zhou Lin also proved this. Excluding the reason for enmity, the police speculated whether the other party was because of emotional entanglements.

Because Zhou Lin is very beautiful and very young, she has always been a very popular technician in their store. According to her colleagues, many customers call for her service every time they come.

Afterwards, the police started with Zhou Lin's private life and focused on investigating the men who had close contact with her and her regular customers.

But after going around, they discovered that Zhou Lin and Xu Yuan actually had a very good relationship, and there were no problems with her private life.

Moreover, on the night of the crime, most of these regular customers had alibi or no motive for committing the crime.

After several people carefully studied these transcripts, Luo Fei slowly spoke.

"From this point of view, it is now basically certain that a stranger should have committed the crime, but it does not rule out that the other party had premeditated it."

"After all, the nature of Zhou Lin's work is somewhat special, and her mother-in-law said that she gets off work very late every night. There is basically a fixed route from work to home."

"After a long time, it is not impossible to be noticed by others, so now we need to start from the place where she disappeared as the center and mobilize all available surveillance cameras in the surrounding road sections to determine where the suspect was abducted and where he was. By some means, he was kidnapped, or maybe the other party is from that area."

"Your analysis makes sense, but the local police must have thought of such a simple problem at the time. Since they still didn't find anything in the end, it means this method may not work."

"That's not necessarily true. The murderer can't disappear into thin air with a living person."

"Nowadays, major roads in the city are under surveillance. No matter how the murderer leaves, he will definitely leave some clues. The fact that the local police did not find it can only mean that they have overlooked certain details."

"I believe that as long as we study it carefully a few more times, we won't be able to find clues."

Luo Fei finished speaking confidently, and the others were indeed convinced.

If they can really find clues from the surveillance, they can save a lot of trouble.

Liao Xingyu stood up directly, "Then I will go to Huangxu City immediately and copy back all the surveillance of the surrounding roads!"

It had only been more than two months since the incident occurred, and the monitoring of such road sections is generally cleared only once every three months.

Naturally, there is enough time.

After saying that, Liao Xingyu immediately set off with Zhou Qian from the second group.

After he left, several people continued to discuss the case.

Li Jun said, "I have another question. Zhou Lin disappeared in Huangxu City. Why was her body found in the river here?"

Not to mention that Huang Xu was in the downstream direction of Jiangzhou. It can be seen from the stones tied to the corpse that the salvage site was the first corpse dumping site.

"There are two explanations for this situation. One is that the murderer was from Huangxu City. He just wanted to avoid the sight of the local police, so he came to our place to dump the body after the murder. To confirm this, we need to confirm that the other deceased are Not all of them are from Huangxu City."

"Another possibility is that the murderer is from Jiangzhou City, but the nature of his work should be that he usually travels to Huangxu or multiple cities."

"Why do you think the murderer often travels between multiple cities?" Zhao Donglai asked.

"It's very simple. We have verified before that there have been no missing women in Jiangzhou City in the past two years, which means that these deceased people are most likely not from this city." "This is why the murderer dared to go to the same place many times with confidence Throw the bodies away, because no one is missing in this city, and even if these bodies are found, it will be difficult for the police to trace them."

"But under normal circumstances, even if a person wants to kill someone, it is impossible for him to go to another city to kidnap someone, kill them, and then bring them back and dump the body."

"This will not only increase the workload, but also increase the risk of exposure. Because he is not familiar with the unfamiliar city, it is difficult for him to determine the road section where he is working, where there is surveillance and where there is no surveillance."

"But judging from the circumstances of Zhou Lin's abduction, the other party was very familiar with the road conditions on that stretch of road, so he could easily take Zhou Lin away without being found by the police."

Zhao Donglai thought about it along with his train of thought and found it very reasonable.

Hearing Luo Fei continue, "In addition, based on the suitcase and backpack used to carry the body, I think the murderer's economic conditions should be average. This way we can narrow the scope a little more when investigating this type of work."

"Well, this is indeed a clue. In this way, we will follow the direction of Luo Fei's analysis and investigate what jobs meet this type of characteristics. Remember to monitor the corpse dumping section within a week from March 3th. Make a copy of the video.”

"You can also check the suitcase and backpack containing the body, especially the box containing Zhou Lin. He was killed not long ago. According to the style of the box, go to stores in the city that sell the same boxes. Let’s go and see if we can pick any traces of the murderer.”

After Zhao Donglai made some arrangements, everyone immediately went down and split up.

Later, reports came from Wuyang City, which is adjacent to them. There were also reports of missing four women there, but no one was found alive or dead.

This number, added together with the disappearance of Huang Xushi, is exactly the number of corpses fished out of the river.

However, Zhao Donglai did not dare to arbitrarily conclude that they were the ones who were killed, so he could only ask the other party to send the alarm records for verification first, and also notify the families of the missing persons to take time to conduct an appraisal.

In this way, everyone was busy until five o'clock in the afternoon.

Considering that everyone stayed up all night last night, Zhao Donglai asked everyone to go back and have a good night's rest before continuing to investigate the case tomorrow.

Luo Fei had dinner in the cafeteria, called Wu Yan and Yang Mei respectively after returning to the dormitory, and then went to bed early.

When we went to work the next day, everyone was revived with full health.

Not long after, Liao Xingyu and his wife, who had gone to Huangxu City for copy surveillance, also came back, bringing Zhou Lin's parents and her husband Xu Yuan with them.

When they heard that a body suspected to be Zhou Lin's was found here, the three of them looked very sad.

Zhou Lin's body was not only torn into pieces, but was also broken into pieces by the water. He was worried that they would not be able to accept it, so he did not let them identify the body.

Zhao Tian personally collected blood samples from Zhou Lin's parents and planned to conduct a paternity test with Zhou Lin's corpse.

After that, the police team made a simple record of the three people, and got a brief understanding of Zhou Lin's daily life and before she disappeared.

The three people's statements were basically the same as before.

After they left, Zhao Donglai called everyone together again.

"Although we are still not sure that the female corpse we picked up is Zhou Lin herself, this is the biggest clue at present, so we can only follow this clue to investigate first. Now everyone can talk about what they discovered yesterday."

Luo Fei spoke first.

“After we went down yesterday, we did a simple search and found that there are many jobs that frequently travel between several cities, such as delivery workers, salesmen, taxi drivers, hawkers... I’m afraid it will take some time to check. "

Liao Xingyu also said, "Yesterday Zhou Qian and I went to retrieve all the surveillance cameras on the section where Zhou Lin disappeared. In addition, we also interviewed her colleagues, and their accounts were basically the same as those in the transcript."

"We visited several merchants selling luggage in the city yesterday. They all said that they had never sold this kind of luggage because the workmanship of the luggage was very rough and it looked like a product purchased online or sold in the wholesale market, so we planned to Let’s go to the wholesale market today.” Li Jun said.

Finally, it was Zhou Fan. He said, "The surveillance of the corpse dumping section and several intersections from Huangxu City to Jiangzhou City have also been copied back. We already watched part of it yesterday, but no suspicious people have been found yet. Or a car.”

Wait for several people to finish reporting.

"Then today everyone will continue to follow the direction of yesterday. Liao Xingyu, today your team will take a look at the surveillance of the section where Zhou Lin disappeared and try to identify suspicious vehicles."

After Zhao Dong finished speaking, he thought for a while and then said, "At present, we are not sure how the murderer transported the body. So Lin Hua, you will take the comrades of the police dog squadron to visit places such as bus stations and train stations."

"receive."

"Then everyone go down and get busy."

The next day, everyone was so busy watching surveillance and visiting.

The family members of the missing persons also came to the police one after another after receiving the notification.

Zhao Tian drew their blood, made a brief note, and went back to wait for news.

It was already four o'clock in the morning when Zhou Lin's paternity test results came out.

When Zhao Donglai received the call, he was still in a daze.

Last night he and everyone worked overtime until eleven o'clock before getting off work.

It wasn't until he heard Zhao Tian saying on the other end that the results were out that he woke up completely.

"How is the result?"

"Through comparison and analysis of the blood of the deceased and Zhou Lin's parents, it can be determined that the deceased is Zhou Lin."

"Okay, okay I understand."

Zhao Donglai was very excited after hearing this.

Because it was determined that the deceased was Zhou Lin, it meant that there was no problem with the direction of their current investigation.

After hanging up the phone, he fell asleep for a few more hours.

He arrived at the police station at seven in the morning.

During the past few days of investigating the case, everyone arrived earlier, but the first one was still Luo Fei.

The first thing Zhao Donglai did after arriving was to take Zhou Lin's DNA identification report and call everyone to the conference room.

"The identification report of Zhou Lin's suspected body came out last night. It can be confirmed that the deceased is Zhou Lin herself. This means that our previous investigation was not wrong. Now let's review the case again."

"Zhou Lin disappeared on March 3, and on July 25, which was the weekend, we found the suspected Zhou Lin's broken body."
