I'm a Super Cop

In the breakfast shop, Gu Chen snapped his fingers, which was completely consistent with his previous guess.
Gu Chen also guessed the other party's psychology. It can be said that he has already surpassed the first step of investigating Zhang Jingde's assassination.
That is, Zhang Jingde was already in danger, and the other party knew everything about Zhang Jingde, so he was able to deal with it calmly.
But Zhang Jingde was completely in a state of ignorance. In such a situation, it was certain that someone would suddenly attack him.
Because from the very beginning, people have already started to assassinate you.
Frowning, Gu Chen hurriedly asked the proprietress: "What did he ask you about Uncle Zhang?"
"Just... just ask if that person is a policeman? I said yes, he is an old policeman here, and he is very popular."
"Then he asked about other things about Officer Zhang."
"Have you asked about Uncle Zhang's recent situation?" Hearing the answer from the proprietress, Lu Weiwei hurriedly asked.
The proprietress nodded silently: "Yes, he asked some more about Officer Zhang's usual situation. I was sorry, so I told him that Officer Zhang's family members are traveling to the Northwest during this time, and he is the only one at home."
"So, Police Officer Zhang likes to settle outside or in the cafeteria when he eats every day."
"Then……"
After thinking about it, the proprietress said again: "Then, I chatted with him about Police Officer Zhang's daily life, and his relationship with our neighbors. Anyway, we talked about everything."
"As you know, we usually do business with acquaintances in a small shop like ours. I think he is also a newcomer, so when we chat, it's easy to catch up."
"I think everyone will get to know each other well in the future, and then you will come to take care of the business a few more times, so I usually share what I know, that's all."
"But I never thought that this person would be detrimental to Officer Zhang, really."
"Okay, I got it." Hearing the anxious reply from the proprietress, Gu Chen could probably guess a thing or two.
In fact, it should be one of his plans to inquire about Zhang Jingde's situation with the proprietress of the breakfast shop.
Of course, if he wanted to know more about Zhang Jingde, the suspect should have asked about many stores that Zhang Jingde frequented, and would have chatted with many neighbors about Zhang Jingde's situation.
Gu Chen suddenly thought that his non-staple food supermarket was also a place Zhang Jingde frequented.
Thinking about his own supermarket, would he have been patronized by this suspect?
Thinking of this, Gu Chen also frowned, feeling that danger was around him.
"Junior Brother Gu." Seeing that Gu Chen didn't respond for a long time, Lu Weiwei also tugged on Gu Chen's arm, reminding him:
"What did you think of?"
"Let's talk about this after we go out." Gu Chen didn't want to reveal it here, so he nodded to the proprietress and said:
"Thank you Madam Boss, if you find that stranger again in the store, remember, don't alarm him first, and then call the police."
"Understood." After receiving Gu Chen's prompt, the proprietress also nodded to confirm.
Afterwards, Gu Chen took Lu Weiwei all the way back into the car, and then drove directly to his grocery store.
In the car, Lu Weiwei was also confused, and hurriedly asked Gu Chen: "Junior Brother Gu, where shall we go next?"
"My supermarket." Gu Chen said.
"Your supermarket? Why?" As soon as Lu Weiwei finished speaking, she seemed to think of something again? Only then did he say:
"Oh, I see, your non-staple food supermarket is also a place that Uncle Zhang often visits."
"If he is being targeted, then this guy will definitely go to your supermarket to inquire about Uncle Zhang's situation, isn't that right?"
"Yes." Gu Chen answered firmly, and then said: "If I didn't guess, this guy must have been to my grocery store. So, I can't let this place go."
The two also communicated in the car for a while, and Gu Chen quickly parked the car outside his supermarket.
Since his parents were taking care of Zhang Jingde in the hospital, all the shop assistants in the supermarket were watching.
Seeing Gu Chen and Lu Weiwei walk into the store, a middle-aged female shop assistant hurriedly asked Gu Chen, "Xiao Gu, I heard that Officer Zhang was seriously injured and hospitalized, is it true?"
"Hmm." Because the clerk here is very familiar with Zhang Jingde, so when his parents stayed in the hospital, they also called to explain the matters in the store.
Therefore, now the entire non-staple food supermarket is aware of the news that Zhang Jingde was seriously injured and hospitalized.
The middle-aged female clerk also frowned slightly, and said incredulously: "Alas! Usually, Officer Zhang seems to be alive and well, but suddenly he was hospitalized and was seriously injured."
"I heard that he may not be able to survive."
"No, Uncle Zhang will be able to survive." Gu Chen didn't want to hear such bad words, so he quickly refuted them while the middle-aged female shop assistant was speaking.
The middle-aged female clerk hurriedly said "Bah Bah" twice, and immediately corrected her: "Yes, yes, Officer Zhang is such a nice person, he will definitely be able to get through it."
After thinking about it, the middle-aged female shop assistant looked at Gu Chen again, with a puzzled expression on her face, and said, "But, Xiao Gu, why did you come to the shop suddenly? I'm watching in the shop, so I'm fine."
"No, I'm here to investigate." While speaking, Gu Chen went directly to the monitoring computer.
The middle-aged female clerk looked confused, and hurriedly asked: "Xiao Gu, what are you talking about? Why can't I understand?"
"Junior Brother Gu means that the murderer who assassinated Uncle Zhang has been investigating Uncle Zhang's whereabouts, so Junior Brother Gu suspects that the suspect may have also come to the store."
"After all, Uncle Zhang often comes to the store to shop."
Afraid that the saleswoman might not be clear, Lu Weiwei hurriedly explained.
The middle-aged female clerk said "oh", and then suddenly realized: "I understand now that you say that."
"If that guy has been to the store, then the store's surveillance system will definitely be able to catch him."
The middle-aged female clerk here is still talking freely, while on the other side, Gu Chen has already called up the relevant monitoring, and began to use his master-level observation skills to quickly investigate the situation in the store.
After a while, Gu Chen discovered the suspect who had inquired about Zhang Jingde at the breakfast shop.
Because the other party was packed tightly in the breakfast shop, it was difficult for the breakfast shop's surveillance cameras to capture that person's face.
Therefore, Gu Chen pinned his hopes on his own store, because the surveillance cameras in the store are widely distributed and there are a large number of them.
No matter from any angle, it can be accurately captured, and Gu Chen is familiar with these surveillance cameras, so the operation is also very simple.
"Have you found it?" Lu Weiwei saw that the corner of Gu Chen's mouth was raised, as if she had already got the answer.
Gu Chen nodded slightly, looked at Lu Weiwei and said, "Actually, this guy deliberately avoided the surveillance cameras on the surface, but he didn't pay attention to the hidden cameras."
"Secret camera?" Lu Weiwei seemed baffled when she heard this.
The middle-aged female clerk hurriedly explained: "That is, some cameras hidden in the interior decoration of the supermarket, and a few humanoid dolls in the supermarket were sent by the supplier."
"The doll's eyes are actually hidden cameras, mainly to monitor some blind spots and achieve full coverage of monitoring."
"So that's the case?" Hearing the middle-aged female shop assistant's explanation, Lu Weiwei also nodded silently, expressing her understanding:
"So I understand. Indeed, if this is the case, then it shouldn't attract the suspect's attention. So, Junior Brother Gu, the angle you can capture here should be this hidden camera, right?"
"That's right." Gu Chen nodded silently, and then turned on the relevant monitoring.
Lu Weiwei and the middle-aged female shop assistant quickly surrounded Gu Chen and watched the situation on the surveillance screen.
At this moment, the suspect was also wandering around in the supermarket at will, while Zhang Jingde was chatting with his father Gu Baichuan near the cash register.
At this time, the suspect was standing near the doll model, closely observing the direction of the cash register.
After a while, Zhang Jingde took a pack of cigarettes and knocked on the counter a few times before getting up and leaving.
After that, Gu Baichuan followed Zhang Jingde out of the supermarket.
After Zhang Jingde left, Gu Baichuan stayed at the door, chatting with the surrounding neighbors about their daily life.
At this time, the suspect bought something casually and went directly to the front desk to pay the bill.
And it was the middle-aged female salesperson in front of him who received him.
Then, the two started chatting.
Seeing this scene, Gu Chen and Lu Weiwei looked at the middle-aged female salesperson in unison.
"So it's him?" The middle-aged female salesperson suddenly realized when she saw this scene:
"I know this man. He came to the supermarket to buy things, and then he chatted with me at the counter for a long time, rambling on and on. Anyway, he finally asked me about Officer Zhang's situation."
"What are we talking about?" Lu Weiwei was also very curious.
The middle-aged female clerk continued to explain: "Anyway, I just chattered and talked about a lot of things. It happened that I was not busy at that time. Anyway, I was idle, so I chatted with him."
"At the beginning, it was quite normal. Later, he casually mentioned that the customer who bought cigarettes just now is very familiar with your boss?"
"I said that is our boss's old friend for many years, can you not be familiar with him?"
"Then he said, that Police Officer Zhang or something seems to be very popular."
"Just rambling, and finally inquiring about some things about Officer Zhang."
"Then how did you tell him?" Hearing this, Gu Chen also looked serious.
The middle-aged female clerk thought about it and said, "What else can I say? What did he ask me? I'll just say what."
"I remember that he also asked some questions, such as, does Officer Zhang come to our supermarket every day? If so, what time is it? Is it usually this time?"
"Anyway, I also felt at the time that this person is quite strange, and he cares so much about a strange policeman."
"Because he is an unfamiliar face, I have never seen him before, so I didn't talk to him too much."
After a pause, the middle-aged female clerk said again: "But I remember it very clearly. He asked me about when Officer Zhang usually comes to the store?"
"Then what do you say?" Gu Chen asked her.
The middle-aged female clerk replied: "I told him that it is usually noon, sometimes before eating, sometimes after eating, and the time is between 11 o'clock and 2 o'clock."
"That's all?" Hearing the reply from the middle-aged female shop assistant, Gu Chen also frowned.
The middle-aged female shop assistant nodded silently: "That's all. After all, I already find it strange that he asks these things. Wouldn't it be even more strange if he asked more?"
"Anyway, another customer came to check out later, so I ignored him, and then he left after paying the money himself."
Speaking of this, what did the middle-aged female shop assistant seem to think of? Quickly said:
"Oh, by the way, he paid in cash. Everyone paid by mobile phone. I thought it was strange that he paid in cash at the time, so I was deeply impressed."
"It's normal." Hearing what the female clerk in his store said, Gu Chen also took a deep breath, and said involuntarily:
"If you pay by mobile phone, it will only expose him, so he will not be so stupid. It is safer to use cash."
After thinking about it, Gu Chen said again: "By the way, is the cash he used still here?"
"Well……"
Hearing what Gu Chen said, the middle-aged female shop assistant also looked confused.
Gu Chen reminded: "Think about it again, after all, there are not many people who use cash now. I saw from the surveillance that he should have paid a 20-yuan note and two one-yuan notes. coins, right?"
"Yes, the coins must have been lost, but the banknotes may still be in the store." Hearing Gu Chen's words, the middle-aged female clerk hurriedly opened the cash register and began to check the condition of the banknotes.
He murmured, "I remember that he and a few other elderly people used banknotes that day. Although the elderly also paid 20 yuan banknotes, they seemed to have more wrinkles."
"And the 20 yuan note he paid there still feels brand new."
According to the narration of the middle-aged female clerk, Gu Chen also opened the cabinet under the cashier counter at home, and began to look for the 20 yuan note according to the narration of the female clerk.
Not long after, Gu Chen found a banknote that matched the description of the female clerk, so he pointed to the inside of the drawer and asked, "Is it this one?"
"Not sure, after all, there are a few days." After the words fell, the middle-aged female shop assistant hurriedly said:
"Maybe? Anyway, paper money is the only cash, usually the elderly like to pay in cash, it should be this..."
Looking at the cash in the drawer of the cash register, the middle-aged female clerk wanted to tell Gu Chen which one it was? So I reached for it.
But it was quickly interrupted by Gu Chen stretching out his hand, and also reminded: "Don't touch it."
The female clerk looked confused, but soon, he understood Gu Chen's intentions.
I saw Gu Chen pulling out a pair of white gloves from his body like a magic trick.
Gu Chen also reminded, "If my guess is correct, the suspect's fingerprints should still be left on the current 20 yuan note."
