"You know, what do you know?"

Seeing Gu Chen's sudden words, Lu Weiwei, who hadn't reacted yet, suddenly stiffened her expression and looked at Yuan Shasha who was coming.

And Yuan Shasha stood in place, looking at the two of them inexplicably.

Lu Weiwei and Yuan Shasha looked at each other, and then set their eyes on Gu Chen.

"Senior Brother Gu, I've already brought the plastic sheeting to keep out the rain. Yuan Shasha said.

"Leave it to Senior Sister Lu. Gu Chen's mind was no longer here, he walked through Yuan Shasha and walked directly to the footprints of his high heels.

Yuan Shasha turned her head to look at Gu Chen and asked Lu Weiwei softly, "Senior Sister Lu, what's wrong with Senior Brother Gu?"

"Shhhh Lu Weiwei still didn't know what Gu Chen thought, so she could only ask Yuan Shasha to bring the plastic sheeting to cover the rain, and the two spread it out on the spot to cover Han Lili's body.

And Gu Chen, on his side, was still studying the footprints on the ground.

"That's not right. Gu Chen shook his head: "If the murderer walked back according to the footprints, it is indeed possible to leave only one footprint." ”

"But in this way, the footprints overlap, which can also cause different sizes, but from the scene, this did not happen. ”

Thinking of this, the idea that Gu Chen had just germinated suddenly felt like being poured a basin of cold water.

Lu Weiwei, who had finished covering the corpse, took Yuan Shasha and walked to Gu Chen's side in small steps.

At this time, the sky was still drizzling, and Lu Weiwei simply opened the umbrella to shield Gu Chen from the rain.

However, Gu Chen's train of thought had just fallen into trouble, and Lu Weiwei's umbrella suddenly enlivened Gu Chen's train of thought again.

"That's right. Gu Chen looked up at the umbrella above, and couldn't help but say happily: "The footprints are like the area under my feet, if you want to block the rain, it is enough to use an umbrella that can be covered." ”

"Senior Brother Gu, what are you talking about?" Lu Weiwei became more and more confused the more she listened, and she couldn't keep up with her train of thought at all.

Mainly Gu Chen handles cases, and he always likes to be surprised.

No one knows when he'll come up with one again.

Gu Chen stood up and asked Lu Weiwei, "Senior Sister Lu, what do you think of the footprints at this scene?"

"Footprints?" Lu Weiwei was stunned, looked at Gu Chen's handsome smile, and said with a light smile: "There are only one footprints at the scene, and didn't you listen to those passers-by? They even said that the murderer had no legs, because there were only footprints of Han Lili at the scene." ”

"The murderer must have legs, but the past was covered up by the murderer. ”

"Cover up?" Lu Weiwei looked at the footprints on the ground and said, "I still don't understand." ”

"Let's put it this way, you take a step back. Gu Chen waved his hand, causing Lu Weiwei to take a step back.

Although Lu Weiwei didn't know what Gu Chen was going to do, she still did as she was told, and took a step back and asked, "What about now?"

Gu Chen didn't speak, but just stepped on it again according to the size of Lu Weiwei's footprints and in the same direction.

Later, when he pulled out the mud, Lu Weiwei's footprints from before were instantly covered by Gu Chen's larger footprints.

"Do you understand?" asked Gu Chen.

Lu Weiwei nodded: "It seems to understand, you mean that the murderer stepped on Han Lili's footprints and retreated, in order to cover up the traces?"

Seeing Gu Chen nodding slightly, Lu Weiwei squatted down, carefully checked the footprints at the scene, and said helplessly: "But...... Are there any narrower soles than these fashion heels?"

Gu Chen didn't speak, just smiled faintly.

Yuan Shasha also didn't know why, scratching her head and thinking.

But Officer Wang, who was standing not far away to maintain order, couldn't help but remind: "Lu Weiwei, have you ever practiced dancing?"

"I've practiced, I've been practicing dance since I was a child, otherwise I wouldn't have the body I have now. Lu Weiwei said.

Officer Wang smiled and said, "My daughter Xiaobei also practices dance, and her practice shoes are as if she is not wearing them." ”

"Practice shoes?" was reminded by Officer Wang, Lu Weiwei seemed to remember something, and quickly looked at her feet.

After a while, Lu Weiwei had an epiphany: "That's right, the soft-soled practice shoes I wore before, there is a rubber shoe board inside the sole, and a leather sole outside the sole, the very narrow kind, it looks like I didn't wear it when I wear it, and the sole is very narrow......."

As soon as she said this, Yuan Shasha seemed to have an epiphany: "Yes, I also practiced dancing when I was a child, and it is indeed what Senior Sister Lu said." ”

"Compared to higher heels, do you think the soles are easy to cover?" Gu Chen asked again.

Lu Weiwei smiled: "Of course, the soles of the high heels are wider, and they can completely cover the soles of the practice shoes." ”

Looking at Officer Wang in front of her, Lu Weiwei couldn't help but give a thumbs up and said, "Lao Wang, there is really you, if you hadn't reminded me, I wouldn't have known that it would be like this?"

"Small meaning. Officer Wang held his head high, and he was also full of presence: "The main reason is that my daughter Xiaobei's practice shoes are worn out again, and I just bought them for her a few days ago, so I suddenly remembered this incident." ”

As soon as Officer Wang said this, the people who were eating melons outside immediately admired it.

"Otherwise, the police are professional. ”

"That's right, so that's the case? The soles of the practice shoes are the narrowest. ”

"Damn, I thought it was a ghost just now, and I thought it was a legless murderer. ”

"Or you have watched too many ghost stories, how can you have no legs?"

"That's right, if you commit a crime at the scene, you will definitely leave evidence, you can't see the evidence, but the evidence is covered up. ”

......

Listening to all kinds of ridicule from passers-by, Gu Chen didn't take it seriously.

After all, now I have found several key directions myself.

The murderer may be Zhang Yaqin, who everyone has been looking for, and this is known through the woman at Amelie Plastic Surgery Hospital.

Perhaps, Zhang Yaqin herself did not notice this detail.

What's more, yesterday Gu Chen called Han Lili, and when it was mentioned that Zhang Yaqin likes to play tennis, Gu Chen obviously felt that Han Lili's situation was wrong.

So much so that when Gu Chen asked Han Lili if she knew where Zhang Yaqin liked to play, Han Lili directly denied it, and then hung up the phone.

Originally, I didn't pay much attention to it at the time, but now Han Lili's body is lying here.

If the murderer was really Zhang Yaqin, then Han Lili had a problem at that time.

"Perhaps, she already knew where Zhang Yaqin was yesterday, but she didn't tell me right away?" Gu Chen asked himself.

Lu Weiwei glanced at him: "You mean...... That phone call yesterday. ”

"yes, that phone call. Gu Chen turned his head to look at Lu Weiwei and said, "I should have discovered the problem a long time ago, but I didn't stop it in time, it's really damn." ”

"Senior Brother Gu, I don't blame you, right? There seems to be a secret between Han Lili and Zhang Yaqin, otherwise it stands to reason that she should tell you that she guessed right. ”

Yuan Shasha also heard Gu Chen's story, only to find out that the original victim, Han Lili, would go to find Zhang Yaqin in private.

It's no wonder that after Gu Chen told her that Zhang Yaqin likes to play tennis yesterday, he didn't go home that night, and he would appear outside the tennis court far away from the Furong Branch.

It stands to reason that she only has 300 yuan on her, and she Han Lili has nothing to do here?

And now through Gu Chen's guidance, Yuan Shasha is also very sure that the murderer who killed Han Lili may really be this "Senior Sister Zhang." ”

"So what now?" asked Lu Weiwei.

"Take the body away and hand it over to the technical section of the city bureau. Gu Chen said.

"And when did she die?" asked Lou again.

Gu Chen glanced at the corpse covered by the plastic rain cloth, and said indifferently: "According to my preliminary inference, the time of death should be around 8 o'clock last night, but the corpse was wet by the rain, which may affect my judgment." ”

"But that's the end result of last night's rain and the exclusion of external interference. ”

"Specifically, there may be errors, so we still need to further verify by Forensic Doctor Liu and Gao Chuanfeng. ”

"I'm calling. After Lu Weiwei finished speaking, she took out her mobile phone.

......

......

After transporting Han Lili's body away, everyone was not idle.

Gu Chen took everyone back to the Furong Branch.

In the offices of the three groups, He Junchao was once again surrounded by everyone.

"I said Gu Chen, I can't blame me for being negligent, everyone was very tired last night, and no one paid attention to Han Lili's situation. ”

"Besides, the people who lived with her didn't find out that she was missing, so we didn't know even more. ”

"That's not what it means. Lu Weiwei interrupted He Junchao and said directly: "What Gu Chen and I mean is that you have always been responsible for the monitoring tasks near the major tennis courts in the city, and now that Han Lili has been killed, Zhang Yaqin can't even find a figure, this is your negligence." ”

"And isn't there a surveillance near this Fushan community? Can't you work overtime? Go to the dispatch room and cooperate? I think you're just too lazy to run. ”

Regarding the killing of Han Lili this time, Lu Weiwei has resentment in her heart, so she needs to find someone to vent.

It just so happened that the monitoring situation had been handed over to He Junchao, and He Junchao bore the brunt of the mistakes.

"Forget it, you can't blame Senior Brother He, after all, the monitoring scope is too big, it is difficult to cover everything, Senior Brother He is alone, and he is not a fairy. ”

"Take a look, look at Gu Chen's mind. Seeing Gu Chen speaking for himself, He Junchao immediately seized the opportunity to refute.

Lu Weiwei said unremittingly: "I don't care what Senior Brother Gu says, but now that this Zhang Yaqin has appeared, shouldn't you take action?"

"Okay, I'll go to the dispatch room again. Feeling like a donkey, He Junchao was powerless to refute.

However, at this time, Gu Chen interrupted: "This investigation is too slow, I'll go to the dispatch room with you." ”

"Okay, let's go over together. ”

Everyone left the office and went directly to the dispatch room.

When a second-class superintendent saw Gu Chen walking in with three group members, he immediately said, "Team Leader Gu, is there something wrong?"

"Yes. Gu Chen stepped forward to shake hands with his senior brother, and said with a light smile, "Can you borrow me the platform?"

"Are you looking for someone again?" Superintendent II was surprised.

Since Gu Chen came to the Furong Branch, the three groups have almost become frequent visitors to the dispatch room.

Gu Chen said, "Find a murder suspect." ”

The probationary police officer sitting in front of the operating platform immediately gave up a position and said, "Senior Brother Gu, I'll leave it to you here." ”

"Thank you. Gu Chen thanked him and glanced at He Junchao beside him: "Senior Brother He, you come to operate." ”

"Okay. ”

What else can He Junchao say? Directly hooked the stool to his side, sat down and began to call up the surveillance near the Fushan community.

After following the distribution of roads in the Fushan community, He Junchao locked down several necessary routes through the tennis courts.

These intersections are monitored and distributed.

He Junchao turned his head to look at Gu Chen and asked, "What about time?"

"Last night around 7pm. Gu Chen said.

He Junchao obediently did so, and adjusted all the three surveillances to about 7 o'clock last night.

At this moment, He Junchao is constantly speeding up the progress.

At around 7:50:33, Gu Chen suddenly shouted to stop.

He Junchao freezes the picture.

At this time, Han Lili appeared in one of the frames.

Many people bit their fingers and carefully checked the picture.

He Junchao then reversed the screen for a few seconds.

In the picture at this moment, Han Lili observed left and right and entered the center of the picture.

"She seems to be looking for someone. Officer Wang said.

Lu Weiwei said: "Maybe it's looking for Zhang Yaqin." ”

"I didn't see Zhang Yaqin in the picture before, so will she follow closely behind Han Lili?" Yuan Shasha also raised her own questions.

But no matter how heated everyone was, Gu Chen never said a word.

It was 7:58:21 p.m.

At this time, a woman with a height of about 170 and a good figure suddenly appeared in the picture.

She was wearing a peaked cap with a low brim, and from the surveillance footage, she couldn't see the appearance of the person who came at all.

But Gu Chen can already know that this is Zhang Yaqin based on the figure and mentality of the woman in the picture.

At this time, Zhang Yaqin was carrying a small satchel in her hand and wearing a pair of canvas shoes on her feet.

"Stop. "This time it was Officer Wang who called for a stop.

He tilted his head forward slightly, staring at the woman in the picture: "This is a pair of canvas shoes." ”

"It doesn't matter if it's sail or not, don't you see that she's carrying a big satchel? Maybe some other shoes are in the bag. ”

Gu Chen also made a general analysis based on the items the woman carried.

After all, to complete the practice of leaving only one kind of footprint on the scene, it is indeed necessary to disguise it with dance practice shoes.

Therefore, Gu Chen had reason to believe that the murder weapon and practice shoes were hidden in the woman's bag.

"It's gone. Seeing the woman leaving the picture, He Junchao also introduced: "This surveillance screen is currently the closest and only surveillance screen to the scene of the crime, and the picture can only see these." ”

"Don't worry, take your time, and by the way, take a look at the surveillance at several other intersections to see if she left from several other locations. Gu Chen said.

He Junchao nodded silently and continued to observe.

The time in the picture quickly came to 8:01:23 last night.

At this moment, among the three surveillance screens, another surveillance captured the woman's figure.

However, at this time, the woman in the picture is wearing a pair of high heels, which are completely different from the previous canvas shoes.

"See, the shoes have been changed. Lu Weiwei pointed to the picture and said.

Gu Chen also came to the front of the surveillance, turned to everyone and said, "See, in a few minutes, this woman stayed for a few minutes in the place where it would have been only a few dozen seconds to pass." ”

And in the past few minutes, Han Lili has not stepped out of the monitoring area, it can be said that Han Lili is standing at the scene of the crime at this time, waiting for the arrival of this woman. ”

"It's just that she's right. Officer Wang's eyes narrowed, and he couldn't help but say: "She first walked to the blind spot of monitoring, and after seeing Han Lili's business in the distance, she directly changed into practice shoes." ”

Then she called Han Lili to the mud on the side of the road, and without saying a word, in the shortest possible time, she stabbed Han Lili in the throat, which made Han Lili, who was not prepared, die on the spot. ”

After that, she changed into the same high heels as Han Lili on the spot, and followed the footprints she had walked in her practice shoes, step by step. ”

In this way, she can cover all her previous footprints. ”

"Senior Brother Wang is right. Seeing that Officer Wang had already finished answering for himself, Gu Chen had no choice but to add: "The soles of the practice shoes are very narrow, so if you put on a pair of high heels, you can completely cover them, and it is difficult to leave traces." ”

"And the time of the crime, to be precise, should be 8 o'clock in the evening as I guessed before, but why is it 8 o'clock? Maybe this is the agreed meeting time between Han Lili and Zhang Yaqin. ”

"Because when you agree on a meeting time, people tend to take a whole number, such as meeting at 7 p.m., 8 p.m., and 9 p.m. ”

"Instead of choosing the so-called 7:30 p.m., 8:30 p.m. and 9:30 p.m. meeting. ”

"Because it is more cumbersome for half a point, people often like to take whole numbers when they make appointments to meet. ”

"That's right. Lu Weiwei very much agreed with Gu Chen's opinion and said, "Maybe they didn't pay attention to these details when they agreed on the time of the mask. ”

But judging from the surveillance footage at the scene, the two people obviously met at a pre-arranged time, and the time was set at 8 p.m. ”

Han Lili arrived a few minutes early, and at 8:01:23, the woman left, and then Han Lili never appeared in the picture again, which also confirmed that the time when Han Lili was killed may be 8 o'clock in the evening. ”

"That's right. Gu Chen nodded slightly, and after scanning half a circle, he said: "And the location of this appointment is likely to be arranged by Zhang Yaqin, or the arrangement of the woman in the picture." ”

"Because she had made an appointment to meet in advance, we had all been to see that place, it was a remote place, and if it wasn't for morning exercises, maybe few people would have passed there. ”

"This is also why, Han Lili was killed on the roadside lawn last night, and was only found and called the police this morning. ”

"It's scary to think about. Yuan Shasha couldn't help but shake her head and said, "In that case, Zhang Yaqin asked Han Lili out with the purpose of killing, and her purpose was very clear, that is, to understand Han Lili." ”

Gu Chen glanced at He Junchao, and said, "Senior Brother He, according to the situation in the surveillance screen, you link up the surrounding surveillance and check the whereabouts of this Zhang Yaqin." ”

"No problem, it's easy to check when you have directions. He Junchao readily agreed.

Previously, because the scope of the investigation was too large, He Junchao could not accurately locate it at all.

But this time, Zhang Yaqin's sudden appearance completely narrowed the scope of He Junchao's investigation and provided convenience for tracking.

After some continuous commotion operations, He Junchao finally found Zhang Yaqin's traces in a location, and said with a light smile: "That's right, this is it." ”
