The murderer's cunning and cruelty really caught Xu Lin off guard.
He had thought before that if useful DNA information could not be extracted from the inside of the corpse, then it would be the same from the bone marrow.
But who would have thought that all the bone marrow of the corpse would be drained out?
Originally, based on the density and tightness of the bone, even if the other party soaked it in a special solution, the genetic structure inside would not be completely damaged within a short period of time.
But now... there is nothing, no way to verify it.
"Team Leader Xu, our people have been dispersed and we are looking for people who have had contact with Li Yanmei. People who had contact with her before she disappeared will be investigated one by one."
More than half an hour later, Zhang Zisheng walked in from outside, still looking a little unhappy.
According to the information they investigated, those people did not have deep contact with Li Yanmei.
There were a few classmates and a few colleagues from the milk tea shop where she worked.
Li Yanmei has been working since she graduated from high school. She is very ordinary-looking and not very good at dressing up, so she doesn’t have a boyfriend. She usually works at home and in the store.
The surveillance during the days when she disappeared happened to be on a road maintenance section, so her sudden disappearance was like evaporating from the world. Zhang Zisheng and others almost lost their hair, and there were no clues.
When Xu Lin heard his words, he nodded calmly.
This case, so far, has almost no clues, just like a headless case.
What they have to do now is to find out the slightest possibility from the cluelessness, make bold assumptions, and humbly seek verification. Only in this way can the secrets of the case be revealed.
Zhang Zisheng did not disturb Xu Lin's contemplation and sat down aside. Li Shu poured him a cup of tea.
On the side, Yang Zhiyun, who had followed Xu Lin, was holding a pen and was writing and drawing.
What he is doing is a psychological close-up of the murderer.
A detailed interpretation will be made based on the traces found at the scene and the circumstances of several murdered women.
Zhang Zisheng walked over with tea and stopped behind Yang Zhiyun.
He carefully read what the latter wrote.
"Age, between 20 and 40 years old, or above."
"Introverted and doesn't like to communicate with others."
"There is hatred towards women, especially... ugly women."
"He has a strong psychological quality and strong anti-reconnaissance capabilities."
"according to……"……
To be honest, after reading these things, Zhang Zisheng felt that they were not very helpful in handling the case. Because there is nothing here that can determine the general scope of the murderer, it is too vague.
He has never been too fond of people who play psychology.
At this time, Xu Lin came over, looked at what Yang Zhiyun wrote, nodded, and said, "Not bad, but... now is not the time to do these profiles."
Assuming the murderer is of little use to Xu Lin.
There is already a new idea in his mind, which always revolves around the time when Li Yanmei disappeared and the time when she was made into a wax figure.
The time overlaps, so according to what Master Jiang said, if it is just a head, there is completely time.
So... where does the body go?
And...if the body is not Li Yanmei's own, then who does this body belong to?
Around these two points, Xu Lin's eyes became sharp.
There is a more important idea, that is, Xu Lin feels that the real target of the murderer may not be Li Yanmei, but someone else.
"Searching for corpses?" After hearing his explanation, Zhang Zisheng's face immediately showed a look of astonishment.
He thought Xu Lin would say something, but he didn't expect that he was looking for a corpse.
But it's not easy to find a body in such a big Yuebin City?
And the murderer wanted to hide the body, how could you easily find it?
This is almost impossible.
"Searching for corpses is only one direction, and the hope is not very high. Our main investigation is in another direction."
Xu Lin paused and continued: "According to my judgment, the murderer's choice of target should not be random. Can you imagine why out of 6 corpses, only one family member reported him missing?"
"Team Zhang, you have searched for missing persons in the past two years. Are there any of these people?"
Zhang Zisheng shook his head and said: "Except for Li Yanmei, I have sent people to investigate the other four deceased people. There is no record of their disappearance in Yuebin City or even in the entire Daxia."
Nowadays, the Internet is so developed that as long as all missing persons have reported a case, they will definitely have a record on their police network.
No, the family didn't call the police at all.
Zhang Zisheng has no doubts about Xu Lin's road recovery ability, otherwise he would not have been able to recognize Li Yanmei at a glance, almost exactly like the one in the photo.
So...for those five victims, the murderer should have been carefully selected.
As for Li Yanmei, there must have been some deviation in the investigation of the murderer.
Bang!
Zhang Zisheng slammed the table, with a glimmer of light in his eyes.
At this moment, there was an idea in his mind telling him that Li Yanmei... might really be implicated.
Xu Lin's voice also sounded at this time.
Just listen to him say: "Go and investigate immediately, Li Yanmei's female friends, or best friends as we usually call them. The most important thing is to check for me whether Li Yanmei had close contact with any female friends before she disappeared, or whether she was in close contact with any female friends before she disappeared. …The two live together.”
As soon as these words came out, Zhang Zisheng's figure trembled slightly.
He said: "I'll go right away."
Soon, the brothers of Yuebin City Criminal Investigation began to take action.
After only 4 hours, they found a target, a classmate of Li Yanmei named Jin Zhenzhen.
They had found Jin Zhenzhen before, but after investigating that there was no connection between Jin Zhenzhen and Li Yanmei's disappearance, they ignored her.
At this moment, when Zhang Zisheng saw Jin Zhenzhen who was taken to the police station, he felt excited all over, as if he had been enlightened, and his whole body became more enlightened.
Jin Zhenzhen looked at the policeman in front of her nervously. For an ordinary person, nervousness is inevitable when entering a majestic and sacred place like the police station.
Creak!
The door opened and Xu Lin walked into the office of the Criminal Investigation Brigade. His eyes immediately fell on Jin Zhenzhen.
This Jin Zhenzhen is about 1.6 meters tall, about the same height as Li Yanmei. The most important thing is that the body shape is also similar, and in terms of appearance, the two of them can be considered to be on the lower side.
Birds of a feather flock together, and it's not unreasonable for them to become best friends.
"Jin Zhenzhen, do you have a boyfriend?" Xu Lin's first words were somewhat unexpected.
