The next day, Du Lin took Liu Guihua to the criminal police team to make a record.

With this transcript, Du Lin thought that finding a time witness would prove that Xu Hui's alibi was a contradiction, but Li Xian's words made Du Lin's efforts useless.

"Lao Du, your evidence is useless, the other party's lawyer can be overturned with a word, because what this Aunt Liu said 'seeing Xu Hui' is just her subjective statement, if I am the defense lawyer, I can say that Aunt Liu is old, her old eyes are dizzy, and she may not see clearly what the person who gave her the umbrella looks like, plus she didn't know Xu Hui before, before seeing Xu Hui this time, she was not familiar with Xu Hui at all, and the possibility of recognizing the wrong person is very high. In addition, there is no circumstantial evidence and no physical evidence, and the court will not accept Aunt Liu's testimony. ”

Wang Jieshu on the side said with a smile, "Li Tou, your rhetoric sounds familiar, how can you have a routine with the lawyer surnamed Zuo?"

"Hmph, I've been dealing with these things for a long time, and I've learned it myself. Li Xian turned to Du Lin again and said, "Even if the court accepts Aunt Liu's testimony, it can only prove that Xu Hui's alibi is fake, or it can't prove that Xu Hui killed someone." As I said before, both crime scenes were handled very cleanly, leaving no clues about the murderer, so we can only prove that Xu Hui had the motive and time to kill, and there is no direct evidence that he killed people. ”

Durin thought for a moment, "Can you take me to the two murder scenes?"

Du Lin first looked at the scene where lawyer Zuo Shaocheng was killed.

Mr. Zuo's home is located in a very good area of Zhonghu City. The security facilities of the community are rigorous, there is a security guard at the door, and there are cameras everywhere in the community. If someone wants to sneak into this neighborhood to commit a crime, it is almost impossible to do it completely without a trace.

It can be seen from the surveillance video of the community that a person wearing a police uniform entered the community at about two o'clock in the afternoon on July 15, and the personal information left in the visitor record book at the door was of course false.

He walked all the way to the unit where Zuo Shaocheng's house was, and after entering the corridor, he never came out again, until more than 7 o'clock in the evening, when Zuo Shaocheng went home.

Just over 20 minutes later, the camera captured this man in a police uniform walking out of the gate of this community.

None of the cameras captured the face of the man in the police uniform, and his height and physical characteristics were different from Xuhui's.

Xuhui is about 1.7 meters tall and weighs only 120 pounds. In the surveillance video, this person is at least 1.75 meters tall and slightly fat.

Although the physical characteristics did not match, Doolin was well aware that physical characteristics could be disguised.

If you want to be taller, you can wear heightened shoes or pads to increase the insole, and if you want to get fat, you can stuff cotton inside your outer coat or wear several layers of other clothes.

For example, the policeman in the surveillance video.

In Zhonghu City in July, the temperature at noon was close to 38 degrees, and the surface temperature was likely to exceed 40 degrees.

In this kind of weather, any normal person will wear short sleeves or even shorts when they go out.

But this policeman actually wore a long-sleeved police uniform that can only be worn in spring and autumn, which is obviously abnormal.

Most likely to change his size, he wore a very thick suit on the inside and a wide, long-sleeved police uniform on the outside as a cover.

Zuo Shaocheng's wife and children are all abroad, so he lives alone in Zhonghu. In the interior of the crime scene, that is, Zuo Shaocheng's home, all the blood stains were concentrated in the area of the entrance of the door, that is to say, the murderer had just used the police uniform on his body to deceive the door open, and without saying a word of nonsense, he stabbed Zuo Shaocheng in the chest. Then cut off his lips, knock out his teeth, and take them away.

Finally close the door and leave the scene.

It is likely that the murderer wore a hood, gloves and mask when handling the body, so there were no footprints, fingerprints, hair, or dander left inside the crime scene.

In Li Xian's words, this is one of the most "clean" scenes he has seen in his nearly two decades as a police officer.

What he said by "clean" does not mean that the scene is neat and tidy, and there are no blood stains, but that the murderer's anti-reconnaissance ability is very strong, and he has not left any valuable traces and clues.

Later, Du Lin inspected the scene of the murder of Judge Jing Zhongge, who also lived alone, and his wife and children lived in the countryside and were not around. This is basically the same as the scene where Zuo Shaocheng was killed, and it is also clean and neat, leaving no traces.

Back at the Interpol team, Durin fell into deep thought.

He can already roughly guess the entire murder process of the murderer:

First of all, by increasing the height of shoes, as well as putting other clothes on the clothes, he changed his body shape and deceived the surveillance cameras in the community.

Then lurk in the corridor of the deceased's house and wait for the deceased to return home.

After the deceased returned home, he used the police uniform on his body to trick the deceased into opening the door, because the two victims need to deal with the police frequently, so it should not be difficult to deceive the deceased to open the door.

After opening the door, the first stab in the chest of the deceased was also fatal.

After the death of the deceased, Zuo Shaocheng's lips were cut off in the first case and all his teeth were knocked out, which means that Zuo Shaocheng's mouth reverses right and wrong and confuses black and white;

In the second case, Judge Jing's right hand was chopped off, implying that he had ruled the case unfairly and was unworthy of the gavel.

Then close the door and leave.

By checking the surveillance camera information around the entrance of the community, it was not found out from which direction the fake police entered or left the community, and it seems that he had observed the blind spots of all cameras in advance.

Then it means that the murderer must have come here before committing the crime and observed the perspective of all the cameras.

But because of this, as long as he has been around here, he will definitely leave traces, because it is impossible for him to hide his traces by camouflage when stepping on the spot, which is too noticeable.

Du Lin thought of this, and Li Xian had already thought of it.

Therefore, Li Xian's main work in the past few days is to repeatedly check the surroundings of the two communities where the crime occurred, and all the surveillance videos taken by the cameras that may capture the suspect in the 7 days before the crime.

Including the police's Skynet system, traffic cameras, urban management cameras, and cameras installed by some surrounding shops, there are about 200 of them, and each camera shoots 168 hours of video content for 7 consecutive days, and 200 cameras are about 34,000 hours.

This is definitely a huge project like looking for a needle in a haystack, and I am afraid that I will not be able to see it all in a month by relying on the dozen pairs of eyes of the criminal police team alone.

In order to complete this work as soon as possible, Li Xian applied to the leaders of the bureau to transfer the police from several police stations near the scene of the crime to check the surveillance video with them.

Because of the seriousness of the case, the lawyer surnamed Zuo is fine, but the killing of Judge Jing has a very bad impact in Zhonghu City, and some people who do not know the truth have begun to post a lot of slander and insult to Judge Jing on the Internet, which has had a very bad impact on the personal image of the deceased and the fairness of the law.

In order to solve the case as soon as possible, the leaders of the Zhonghu City Public Security Bureau can be said to have responded to Li Xian's requests. Soon, a total of 40 community police officers from 11 surrounding police stations joined the case-handling team.

One of them was at the Garden Street police station near the scene of the crime, and three of the four people came.

"Alas, Director Lei, there are only 4 of you in total. There are 3 of them, what can I do with the work in that institute?" Li Xian held the hand of Director Lei tightly, and thanked him sincerely.

"It's okay, I also left a deputy director to sit in our garden office, and the old leaders of our team are also there to help, so I don't have to worry about coming to your criminal police team. ”

"Who is the old leader of our team?" Li Xian was a little puzzled, not knowing who he was talking about.

"Oh, you don't know it yet, it's the old captain of our city bureau's criminal police team, your old leader Lu Zhongshan!"

"Old Captain, is he there to help you?"

"But no, since the old captain retired from illness, he said that although his own health is not very good now, he can no longer engage in criminal investigation work, but it is still okay to take care of trivial things at the police station. So there's nothing to do, just always soak in our Garden Street police station, take care of the mother-in-law and daughter-in-law quarrel today, and help find the lost pet dog tomorrow, day by day is also very fulfilling, in his own words, it is better than nothing. You also know," Director Lei said in a low voice close to Li Xian's ear,

"Since the old captain's family accident, the old captain is too stressed, both psychologically and at work, now retired, cold and idle, it is estimated that he will not adapt for a while, he took the initiative to find me, want to help in the office, we can't push people out, right? ”
