It's likely that Lao Yan is still alive, otherwise that bastard would have killed him in the room and wouldn't have to take him out of the police station at all at great risk. Although there is a shortage of manpower in the police station, in the final analysis, the place where Lao Yan stayed at that time was still in the Jing'an Port City Bureau, and if there is the slightest mistake in any of the links, that bastard will most likely be sent directly to prison, saving us from arresting him later.

In the usual style of the murderer, after he took Lao Yan out of the city, he was likely to take him to a secluded place first, wait until the situation stabilized, strangle him with a string, and then carefully peel off Lao Yan's skin.

As with the average serial killer, the killer will enjoy the pleasure of torturing his prey because of his deformed psychological state.

Therefore, the good news is that until the goal is achieved, Lao Yan's life will not be in danger for the time being. The bad news is that no one knows where the murderer took Lao Yan and when that bastard will choose to do it.

I don't want the next time I see Lao Yan again, what appears in front of me is a dead body that has been skinned. So, even if there was even the slightest possibility, I would do my best to rescue him and arrest that skinning bastard with my own hands.

Calm down, all I can do is use the knowledge I have to make a rational analysis little by little.

Judging from the situation at the scene, it is likely that after the other party entered the room, he probably used an anesthetic similar to chloroform to stun Lao Yan, and then took him out of the room. Although Lao Yan is old, he used to be a criminal policeman, and he has certain hand-to-hand combat skills and the ability to resist.

At that moment, Lao Yan should also know that once he was taken away by the other party, then he would have no way to live. So before he fell unconscious, he fought desperately against the murderer. And the books scattered on the ground, and a small pool of blood, are the best evidence.

The surveillance footage that the police found later also largely supported my earlier reasoning.

The footage shows that at around 9:05 p.m., a sanitation worker wearing a light blue suit and a mask entered the police station. After that, the sanitation worker never came out again, the video shows that after the sanitation worker entered the city bureau, he walked directly through the hall and walked towards the office where Lao Yan was.

After figuring out the specific situation, Tang Yan immediately ordered the police officers in the Jing'an Port City Bureau and the members of the Criminal Investigation Brigade to take action to search for Lao Yan's traces in the whole city.

Colleagues from the communications department also extracted the appearance of the suspect in the surveillance footage, and did their best to restore the suspect's original appearance through science and technology, and conducted a city-wide search.

However, Jing'angang City is too big, and it is enough to search the entire urban area, not to mention the neighboring affiliated towns and so on。。。。。

In addition, the suspect entered the city bureau with a mask, and the face restoration work was not going smoothly, and if you want to rescue Lao Yan with this, in my opinion, the possibility is very small.

What to do? What to do! Every second that passed, Lao Yan was one minute closer to the death line. There are very few clues left at the scene, and we can't even confirm where the bastard came out of the police station, and if this continues, there is a good chance that only Lao Yan's body will be left after that.

At this moment, Tang Yan also seemed to see the entanglement in my heart, and while he continued to arrange the search plan for Cheng Zhimin, he leaned over and comforted in a low voice: "Now that the matter is over, the police will definitely do their best to rescue Teacher Yan." It's just that Gao Fei, compared to the entanglement and self-blame, you should do what you can do! ”

Looking at Tang Yan's sharp eyes, I was a little stunned for a while.

"What can be done? At this time, what else can I do for Lao Yan? ”

"What can I do!" Tang Yan narrowed his eyes, and at the same time couldn't help but say sharply: "I know Yan Shusen too well. Cunning rabbit three holes, his old fox will definitely not sit back obediently, I believe that with Yan Shusen's ability, he will definitely leave important clues or hints at the scene.

If Yan Shusen really left something behind, looking at the entire Jing'an Port City, only you can decipher it. So, Goofy, the only thing you can do right now is calm down and find those skinning bastards in the way you do best!

Anyway, the situation has gotten so bad that why not give it a go? If you want to prove that Lu Yuan is innocent, if you want to rescue Lao Yan, now, do it to me! ”

Tang Yan's words woke me up forcefully.

Indeed, I can't continue to sit back like this. I've lost so much since seven years ago, and I've seen too many people die.

Lao Yan has worked hard for most of his life, and his academic research has made outstanding contributions to the entire field of criminal investigation and even to the Z University Police Academy. At the beginning, in order to save Lu Yuan, I also insisted on pulling Lao Yan to Jing'an Port City. So now, it's only Lao Yan, and I don't want him to die like this in the hands of that bastard.

Clues, hints!

I have to say that Tang Yan's words really reminded me.

At this moment, I suddenly remembered what Lao Yan said to me at the end: "Didn't we always wonder before, the murderer obviously used the same method of killing and skinning, but why did the situation reflected at the scene of the murder look like there were six people committing the crime?" Now, I've finally figured it out! In fact, there was only one person who was the real murderer from beginning to end, and we were all tricked by that guy! ”

This is Lao Yan's original words, judging from his excited tone at the time, Lao Yan should have mastered some very key clues before he came to such a conclusion. Unfortunately, if I had been able to patiently listen to his follow-up words at that time, the current situation would have been completely different!

I told Tang Yan my guess, and after Tang Yan thought about it, he hurriedly asked the members of the forensic department to count the files scattered on the office floor.

Fortunately, although this office has been closed for a long time, every file and file in it is recorded on the computer. Through everyone's unremitting efforts, we finally found that in the huge office, there was a file that recorded the items left behind from the murder scene seven years ago.

In this way, Lao Yan should have found some very crucial information on that file. And the murderer happened to rush into the office at that time, not only knocked over Lao Yan, but also took the file with him.

It seems that the file should really hide important information, so that it aroused the alarm of the deadly bastard, but I don't understand what was recorded in the items left at the scene so that Lao Yan could conclude that "there was only one person in the real murderer from beginning to end"?

I took a deep breath, tried to clear my mind as much as I could, and filtered through my mind everything that had happened from the beginning of the peel case to the present.

Now, we have lost all the evidence and means we can rely on, and what is worse, Lao Yan's life is still in jeopardy.

Therefore, if I want to reverse the bad form, if I want to give it a go, then there is only one thing I can do right now: unconditionally believe in the judgment made by Lao Yan at the beginning!

The four cases seven years ago, plus the murder of Shanying and Team Leader Wu, a total of six skinning cases, were all committed by the same person!

However, the cycle spanned by the first four cases and the next two cases is too long, and the crime scenes left behind after the crimes are completely different.

I don't think the killer did it on purpose, because it's unlikely that a serial murderer's cooling-off period will last as long as seven years. Crucially, once a prisoner has become accustomed to a certain modus operandi and the way of disposing of corpses, it is very difficult to make changes.

To sum up, I can only think of the only possibility that can fit the above inference.

Of course, if I want to confirm this possibility, right now, I need to meet with someone.

I hope that for Lao Yan's sake, Lu Yuan can help me this time.
