"Can we find the murderer based on his gait?" Fang Zhenyue also walked closer and turned to ask Ajie.

"It's difficult. It's already difficult to identify the murderer based on footprints, let alone gait. Unless you find the suspect first and then collect the suspect's gait traces for comparison, it's not easy to get this evidence." Ajie spread his hands helplessly.

Fang Zhenyue and Jiayi both fell silent.

Ajie looked at them and realized that he had been saying sad words. He quickly cheered up and smiled, "But it's not impossible."

"Thank you." Fang Zhenyue nodded to Ajie, and Ajie turned around to look for other clues to take pictures and collect.

"What did you find?" Seeing Ajie leave, Fang Zhenyue retracted his gaze and looked at Jiayi.

Has she been lost in her own emotions and thoughts recently? Is there something going on that he doesn't know about?

Jiayi raised her head. The loneliest thing in the world is to keep a secret all by yourself.

When a reliable senior like Yue asked her about it, it was undoubtedly a huge temptation for her.

She could tell others about her discoveries, those secret clues, those smoldering emotions in her heart...

Her lips moved slightly, she raised the corners of her lips, crooked her eyes, and said softly: "No, I'll think about it."

"Yeah." Fang Zhenyue stared at her for a while before changing the subject:

"The murderer's method is very good. He was able to fire two shots in a short period of time, and the gunshots hit the back of the head of the deceased. This is obviously not something that ordinary people can do. Most people, even if they get the murder weapon, find it difficult to use it so... with ease."

He avoided the word "well used" and used the word "with ease" instead.

"He was so careful to erase the fingerprints and face of the murderer. Obviously, he is a cautious person. On the first level, he didn't want the police to find out the identities of the two deceased." Jiayi nodded.

When detectives Liang Shule and others saw Jiayi and Fang Zhenyue discussing the case, they immediately gathered around.

Among them was Xu Shaowei.

Jiayi scanned several detectives, and although she knew Xu Shaowei was looking at her, she continued:

"On the other hand, he did not destroy the victim's car or the fingerprints in the car.

"First of all, he did not want to leave more traces for the police when destroying the victim's car and the fingerprints in the car.

"Although the murderer rubbed off the face and fingerprints of the corpse in order to hinder the police investigation. But he did not want to do unnecessary things and expose himself.

"The murderer is obviously a very smart person, and has strong anti-detection capabilities. All his actions must have been carefully calculated, and the gains and losses of each thing must have been repeatedly considered.

"The gains from grinding off the body's outer hat features and fingerprints outweigh the losses, so he did it.

" Then the fact that the victim's vehicle and the bloodstains at the crime scene were not destroyed shows that in the eyes of the murderer, destroying this information might expose him more, and the benefits would not be worth it. "

Liang Shule's eyes widened as he quickly recorded Jiayi's words, only to find that his writing speed could not keep up with Jiayi's thinking.

He had always thought that even if he was very smart, he would often be complacent because he could find things that other uniformed police colleagues could not find. In the past few days of supporting the serious crime team, he realized that professional detectives were indeed stronger and he was not good enough.

Xu Shaowei listened to Jiayi's words. If he was not the murderer, he would definitely praise her at this moment.

Every word she said was right, and every word was his plan.

He looked at her young and beautiful Looking at her beautiful and resolute profile, when people appreciate a beautiful thing, they will inevitably smile, and the corners of his lips also curled up, but the smile was full of bitterness.

But he still had this expression, looking at her without blinking, even though his hands and feet were cold because of her words, and even though the wind blowing through the buildings took away his body temperature. He

had been angry, regretful, and all kinds of emotions that were difficult to describe. Here, it finally came to an end.

Surrender?

He was stunned, his lips trembling slightly.

Liu Jiaming suddenly walked to his side, put his arm on his shoulders, stomped his feet, listened to Jiayi and Yue Ge's analysis, and occasionally muttered:

"Wow, the wind here is so strong, it makes me shiver. "

She felt the place where Liu Jiaming's arm was around her getting warmer. With the corner of her eye, she saw that he was obviously not as tall as her, but he pretended to be tall to put his arm around her shoulders. Some thoughts began to flash through her mind again.

"If that's the case... it may be difficult to find out the relationship between the murderer and the two victims." Fang Zhenyue immediately understood what she meant.

Jiayi nodded.

"Let's wait and see if we can find other clues." Fang Zhenyue frowned and turned to look at his busy colleagues in the Forensic Department.

What was the relationship between the murderer and the victims, and why did he kill the victims?

Did the murderer find the victims, or did the victims find the murderer?

"When we go back, we will do as usual and check the identities and social relationships of the two victims. Even if we can't find the connection between the deceased and the murderer, maybe someone has seen the murderer and the deceased together."

Jiayi thought for a moment, and then said:

"Knowing these two deceased people, at least we will have a better idea of ​​many things.

"Put together the cases other than the underwater double corpse case, the dead old policeman, the big robbery case in which the old policeman's gun was used, all the people who appeared in these cases..."

Jiayi paused here, her eyes flashed, she took a deep breath, drove away the emotions that were stuck in her throat, and continued:

"Investigate one person at a time, replay the case over and over again, and peel it off again and again, looking for clues that may have been missed... maybe we can find the relationship between these people."

"What a big project!" Uncle Jiu exclaimed.

"We don't lack time." Sanfu also showed a resolute expression.

Everyone fell silent. After a few minutes, Jiayi turned to Fang Zhenyue and said,

"Brother Yue, leave Brother Gary and Brother Jiaming here to accompany the colleagues from the Forensic Department to do the on-site investigation. Let's go back and continue the investigation."

"OK." Fang Zhenyue nodded, "Gary, you two can take the Forensic Department's car on the way back."

After saying that, Fang Zhenyue turned around and took the lead to stride out of the ruins of the tenement building. As he walked, he deliberately fiddled with the key in his pocket with his fingers, making a clacking sound.

Jiayi listened to the sound and couldn't help but follow the rhythm with her steps, stepping on the sound of the key clacking with every step.

Suddenly, she raised her head, turned to look at Xu Shaowei, and then said to Fang Zhenyue:

"Brother Yue, I thought of something else."

"What?" Fang Zhenyue slowed down.

"Forensic officer Xu Sir said that the deceased died around New Year's Day. You see, although the buildings around here are not dense, I just went to the toilet, and the nearest villagers don't live very far away. If the murderer fired a gun here, the villagers over there should be able to hear it. But I asked, and they all said they didn't hear any gunshots." Jiayi looked up at Fang Zhenyue, her eyes burning, and said:

"I guessed how the murderer silenced the gun."

Xu Shaowei raised his head.

"How did he do it?" Fang Zhenyue raised his eyebrows.

"Just like the sound of me stepping on your key, the murderer fired the gun when the fireworks and firecrackers sounded on New Year's Eve." Jiayi frowned. At this moment, even she couldn't help but sigh: What a meticulous arrangement.

If she hadn't seen it in her mind flow image -

her thoughts paused, and her expression froze.

If Xu Shaowei hadn't met her...

...

...

Back at the police station, Fang Zhenyue led everyone to set up a battle formation to investigate according to the existing clues, and his BB call suddenly kept beeping.

He pinched the pager to take a look, picked up the receiver and dialed the number on the message. After a few simple words, he frowned.

"The informant accidentally came into contact with Qian Guibang, so we can't follow him anymore. Let's take turns to keep an eye on Qian Guibang. When I find other informants, we'll switch back and continue investigating the '91 case.'" Fang Zhenyue turned to the detectives.

Jiayi raised her eyes. In investigating the 91 case, Xu Shaowei was useless, and even... he should be sent to follow Qian Guibang, but she couldn't let him go with the other detectives.

Moreover, she knew that Qian Guibang was the murderer who killed the landlord, but the others didn't know. Now everyone still suspected that the landlord's wife was the murderer. If other people came to follow Qian Guibang, they would only follow him as a suspect and not take him seriously enough, and they might miss important clues.

Thinking about it, she said decisively:

"Brother Yue, Shaowei and I will go and keep an eye on Qian Guibang."

"..." Fang Zhenyue raised his eyebrows again. Jiayi had just shown a strong desire to solve the 91 case, so why did she suddenly propose to keep an eye on Qian Guibang?

This kind of surveillance work does not require Jiayi to go out at all. She should stay and use her smart brain to find clues in the 91 case that others might miss...

After a few seconds of silence, Fang Zhenyue turned his head and looked at Xu Shaowei. Although he couldn't figure it out, he still nodded in inertia and respected Jiayi's proposal.

...

Jiayi kept thinking on the way to the current location of Qian Guibang provided by the informant.

Brother Da Guangming had recorded the gait and footprints of many people before, and analyzed the differences in the footprints of different people. That was when Uncle Jiu's case of Ximing's death was just solved.

And Xu Shaowei was brought to Team B by Inspector Qiu Susan in the next case [the murder of Zhao Dongsheng on Shi Xun Road]. Jiayi still remembers that Qiu Susan brought Xu Shaowei over, and Brother Yue arranged for him to be hers. She took Xu Shaowei to the rich villas on Shi Xun Road, knocking on doors one by one to look for witnesses and collect clues. She told him how to observe others and how to dig out clues behind obvious things... In short, when Xu Shaowei joined Team B, was the activity of Brother Da Guangming collecting gait footprints and giving away lollipops over?

When she returns to the police station, she may go to the Forensic Department to ask Brother Da Guangming.

In addition...it is easy to figure out the connection between Xu Shaowei and the murder of the old policeman. He used to be the old policeman's subordinate, and many painful things must have happened to him at that time. Although the police's job is to protect citizens, there will always be good and bad policemen in the police force with tens of thousands of policemen. This is also the meaning of the existence of the Complaints Bureau and the Independent Commission Against Corruption. Jiayi collected some clues at the Hung Hom Village Police Station. The old policeman was probably not a gentle, kind and good-tempered senior leader when he was alive.

And the big robbery that happened afterwards is also very clear. He got the old policeman's gun and was short of money.

But he and those two people...

Jiayi suddenly raised her eyebrows. Aren't there just two people who robbed the bank with Xu Shaowei? !

Turning her head to look at Xu Shaowei, she almost blurted out to ask him if the two dead were the ones who robbed the bank with him. She

closed her lips tightly and held back.

After a moment of silence, Jiayi couldn't help wondering:

If the two victims were the ones who robbed the bank with Xu Shaowei, and the social relations of these two people had nothing to do with Xu Shaowei, Xu Shaowei didn't worry at all that the police would find these two people.

Then...how did Xu Shaowei find these two people as his partners to rob the bank together? It's

impossible to just find two people on the street and dare to bring them together to risk their lives, right?

Continuing to think about various doubts, Jiayi drove Uncle Jiu's car to the place mentioned by the informant.

After parking the car outside Lai Fu Ice Cream, Jiayi looked out and saw Qian Guibang sitting in the window.

After turning off the engine, she sat quietly for a while, trying to get her thoughts back, and looked up all the traces and behaviors of Qian Guibang that the informant had provided before, and began to look through them while keeping an eye on him.

Xu Shaowei sat quietly on the side, so she tried to restrain her impulse to look at him and concentrate on the documents in front of her.

A few minutes later, Jiayi suddenly frowned, quickly spread out the documents in her hand in front of her, took out the red marker that she had always kept in her pocket, and drew horizontal lines on several confessions.

A few minutes later, she looked at Qian Guibang who was sitting at the window having breakfast in disbelief, and then turned to look at Xu Shaowei.

"What's wrong?" Xu Shaowei, who had been distracted, retracted his thoughts. It was rare for him to see her interact with him like this.

"Look." Jiayi showed him the documents in her hand, "He has been wandering around these days, these are the places he often lingers... This is a bank, this is a gold shop, this is a jade antique shop, this is also a gold shop..."

Xu Shaowei frowned, raised his head and looked at her, "Do you suspect he is going to rob a bank?"

Jiayi frowned and said solemnly: "He is the suspect who killed the landlord... If we assume that he is the murderer, and he has a gun, and happens to be short of money... What do you think he will do?"

Xu Shaowei said harshly: "Rob a bank or a gold shop."

Jiayi was silent for a while, put aside other thoughts, looked around, and soon found that there was a small gold shop opposite Lai Fu Ice House!

Turning back to look at Qian Guibang, Jiayi's expression became solemn.

When she just parked the car, she was still thinking, fortunately Qian Guibang was sitting at the window, otherwise it would be inconvenient for them to monitor.

Only then did she understand that Qian Guibang was sitting at the window just to observe the gold shop opposite!
