Ah Wei's body was sent to the technical department.
In the final analysis, it is to detect the time of death. In this regard, forensic doctor Liu is more professional.
Gu Chen, Officer Wang and Lu Weiwei are now going to the community monitoring room to retrieve Wang Zhe's relevant videos.
At this moment, the control room was also in chaos, and the few police officers who rushed in shocked the security guards.
A murder case suddenly occurred in a usually peaceful high-end community. This is also a huge challenge for property management.
The most direct manifestation is that there will be some challenges in collecting monthly property fees...
Although they charge high property management fees, they cannot guarantee the safety of residents in the community.
I can’t get rid of this pot...
"Have you found the surveillance camera?" Officer Wang stood directly next to a property security guard and began to urge him.
It looks like the security guard doesn't look like a skilled worker.
"Oh, I found it. Let's see if it's him." The security guard quickly stepped aside and said with a smile, "I don't have much experience in handling this thing. I'm sorry, everyone."
"This is the main unit entrance, right?" Officer Wang actually didn't care about this. All he wanted was the answer.
"Yes, whenever you go upstairs, this surveillance camera can capture it," the security guard said.
"Please help me set the time back to 12:20," Gu Chen said.
"No problem." The security guard agreed readily and directly operated the mouse to return the time to 12:20.
Sure enough, Wang Zhe appeared at the exit of the corridor at this time.
After looking left and right at the door for a few times, he left the community leisurely.
"It seems that he didn't lie. He did leave after lunch." Lu Weiwei stood aside and said.
"We can't draw conclusions now and push back the time." Officer Wang didn't believe that things would be so simple.
Afterwards, time began to accelerate at 2.5 times speed, and several people walked out of the unit building one after another.
Security confirmed that they were all residents of this building.
It was not until nearly 2 p.m. that Awei's neighbor, the reporter Zhao Mei, walked into the unit carrying a bag.
Officer Wang checked the time of handling the case and the time in the surveillance video, and couldn't help but frown.
"After Wang Zhe left, only Zhao Mei walked into the unit building, and she was the one who called the police." Lu Weiwei couldn't help but become confused after seeing the whole process.
"There is still a problem. Could it be that someone else in this building has done something wrong?" Officer Wang said helplessly, and then looked at Gu Chen: "Gu Chen, please tell me."
"It's unlikely." Gu Chen also made his own judgment.
"Yes, the deceased Ah Wei himself was not a sociable person. In this building, he only had a good relationship with his neighbor Zhao Mei, but..."
"But if it's Zhao Mei, the time to take action is too short." Officer Wang took Lu Weiwei's words and said.
"I also agree with Senior Sister Lu." Gu Chen hesitated for a few seconds and explained: "If we calculate it based on the time when we received the report, then during this period, Zhao Mei could only just get on the elevator and then go directly to Awei's house.
, without saying a word, he stabbed Ah Wei in the vital part with a knife and killed her. Only then can we ensure the continuity of her reporting time, otherwise it would be too hasty."
Lu Weiwei suddenly looked at Gu Chen with big eyes.
Yes, what Gu Chen just said was exactly what he was thinking.
If we assume that the murderer is Zhao Mei, then she acted too hastily and had to start acting as soon as she entered the door. This is basically unlikely.
"Could it be Wang Zhe? But he left Awei's house around 12:18, and Awei was not dead at that time."
Officer Wang suddenly looked at Gu Chen. Whenever he encountered a worrying problem, he would look at Gu Chen.
He knew that Gu Chen's reasoning and analysis abilities were far superior to his own.
However, Officer Wang couldn't tell whether Gu Chen could help, or that Gu Chen also encountered difficulties.
"Gu Chen, do you have any questions? If so, you can tell me, and maybe we can discuss it together."
Having worked with Gu Chen for a long time, Officer Wang also noticed some of Gu Chen's little habits.
Frowning means that he is thinking, especially after expressing his opinion, he suddenly becomes quiet, which shows that there are still some aspects that Gu Chen cannot prove.
"Senior Brother Wang." Gu Chen hesitated for a moment and said, "Although this Wang Zhe killed someone at a wrong time, I still think there is something wrong with him. If possible, I would like to go to the scene again to have a look."
"Of course. I'll ask Lu Weiwei to accompany you. If anything happens, you can report to me at any time." Officer Wang looked at the monitoring screen and said, "I'll stay here and continue to investigate other possible people around the community."
"Okay!" Gu Chen agreed readily.
When we arrived at Ah Wei's house, the door was still cordoned off, and two auxiliary police officers were talking.
Zhao Mei, on the other hand, had her door closed and was probably hiding at home.
When you encounter something like this happening around you, you will inevitably be a little frightened.
"Gu Chen, Lu Weiwei, do you have any progress in the investigation?" one of the auxiliary police officers asked.
"Not yet, but I guess it will be soon." Lu Weiwei said, holding up the cordon and getting into the room.
Gu Chen didn't say anything and walked in closely behind.
It should be said that Gu Chen has been thinking about a question along the way.
That is, what is going on with this cigar?
According to the cigars on the counter at home, and through chatting with dealer salesmen, I can tell that the burning time of this kind of cigar is generally about 1 hour and 25 minutes.
In other words, when everyone arrived at the scene, which was around 2:25, the cigars had been burning for a full hour.
Then the time of the crime must be between 1:25 and 2:25.
But who has been here during this time?
Gu Chen didn't know, but he was more suspicious of Wang Zhe.
"Junior Brother Gu, what are you thinking about?" Lu Weiwei couldn't help but ask when she saw the absent-minded Gu Chen.
Gu Chen shook his head and rubbed his temples with his hands: "I just have a headache."
"Then I'll check again, you rest first." Lu Weiwei once again walked to the place where Ah Wei was killed, as well as his room, kitchen, etc. Lu Weiwei would not miss every detail.
Gu Chen sat on the sofa, pretending to rub his temples, gradually closing his eyes, and using his entry-level imagination to open the virtual space in his mind again.
This time, the space Gu Chen simulated was the Japanese food store last night.
Officer Wang and Lu Weiwei were chatting with each other. Gu Chen snapped his fingers and soon separated from his body in the virtual space and walked to the dining table behind him.
At this moment.
Ah Wei and Wang Zhe were sitting there having a meal, and the atmosphere was a little tense.
"Master, this is your last chance. Please give me some grace." Wang Zhe's tone was slightly pleading, as if he was asking for help from Ah Wei.
Unlike that night when Wang Zhe had his back turned, Gu Chen was able to restore the expressions of the two of them at close range this time.
Wang Zhe's face was full of pleading, as if he had encountered something very difficult and urgent to solve.
At this time, Gu Chen looked at Ah Wei on the other side again.
Ah Wei flipped up his graying hair and glared at Wang Zhe angrily.
"Ah Zhe, it's not that the master doesn't want to help you." Ah Wei's tone was very angry, and he sighed heavily: "But look at what you are doing, you want me to help you, well, you do
Give me a result."
At this time, Gu Chen had already carefully considered the expressions of the two of them.
Yes, Awei's attitude towards Wang Zhe was quite angry. It seemed that Wang Zhe had done something big wrong, which led Awei to scold him severely.
At this time, he looked at Wang Zhe, still looking at Ah Wei with a weak look, and begged: "Master, I don't dare to do it anymore. Please believe me, I am also helpless."
Gu Chen turned to look at Ah Wei, whose expression didn't seem to change much.
He just said lightly: "Okay, I don't think I can eat this meal today. I will give you another day. After one day, what should I do?"
Just like the scene last night, Ah Wei picked up his bag and walked away, leaving Wang Zhe sitting there alone.
"There seems to be a deep conflict between the two of them, but why did Wang Zhe say that he had already settled all the questions with Ah Wei during lunch today?"
Gu Chen stood beside Wang Zhe and looked at him with his hands clenched into fists, looking unwilling to do so.
Then, Wang Zhe's eyes began to be filled with an evil murderous aura.
He picked up the chopsticks on the table and began to enjoy the food alone.
Gu Chen simply chose to sit opposite Wang Zhe.
At this time, Wang Zhe's eyes became more ferocious with every bite he took.
"It doesn't feel like this guy is here to eat, but rather looking for sin. In this case, the food in front of you is also bland, right?"
Gu Chen kept staring at Wang Zhe's expression changes...
It is clear.
Wang Zhe's hatred for Ah Wei at this moment has almost reached zero point.
After finishing the last piece of food, Wang Zhe slammed his chopsticks and started walking to the cashier.
The scene that follows is what your clone sees in the virtual space.
There were band-aids and bruises, and Wang Zhe's face had an unusual smell.
"It seems that Wang Zhe had murderous intentions towards Ah Wei, but how did he hide it?" Gu Chen couldn't help but hold his chin and snap his fingers.
Soon, the virtual space came to Awei's house again, and it was already noon.
Indeed, Ah Wei entertained Wang Zhe at home, and the two sat at the dining table and continued to discuss yesterday's topic.
But what is it specifically? Is it the shooting problem that Wang Zhe said? Gu Chen thinks it is not.
Afterwards, Gu Chen could only simulate the scene of the two arguing at the dinner table, and Ah Wei even slapped the table at one point.
At this moment, Wang Zhe's emotions exploded to the extreme.
When Awei wasn't paying attention, he walked to the kitchen, picked up a fruit knife, and stabbed Awei directly in the heart.
Awei died instantly, with no time to react.
Seeing that he had killed his master, Wang Zhe suddenly panicked. He wiped off the fingerprints on the knife and began to desperately remove the traces.
After everything was settled, Wang Zhe calmed down, looked down at the time, and then swaggered... and walked out of the room pretending to be nonchalant.
At this point in the simulation of the scene, Gu Chen suddenly snapped his fingers, and the world began to spin. Gu Chen slowly opened his eyes and looked at the burned out cigar on the table.
"Yes, the burning time of the cigar may be a trick. If you use the burning time of the cigar, maybe at 1:25, Ah Wei is still smoking, which means that he is still alive. But if there is no cigar, then Wang
The time when Zhe committed the crime can basically be determined."
Gu Chen suddenly muttered to himself, which made Lu Weiwei on the side quite curious.
Lu Weiwei was stunned and asked: "Junior Brother Gu, what are you talking about?"
"Senior Sister Lu, is there anything suspicious near the cigar?" Gu Chen suddenly stood up and looked at the ashtray on the table.
"No." Lu Weiwei said this, and suddenly said: "By the way, I also found an astronomical telescope. It seems that this Awei is still an astronomy enthusiast."
"Astronomical telescope?" Gu Chen frowned and looked directly at the table.
On the table by the window, a black astronomical telescope is set up on the windowsill of the living room.
Gu Chen quickly stepped forward, looked at the ashtray on the table and the extinguished cigar, and couldn't help but said happily: "I know, I know how Wang Zhe used cigars to create alibi, this guy
It’s really cunning.”
"Junior Brother Gu, you said you already knew?" Lu Weiwei was also surprised and asked: "Then you mean that the murderer is Wang Zhe?"
"It's 100% him." Gu Chen stopped being subtle and pointed directly at the astronomical telescope and said: "This guy used the characteristics of the astronomical telescope to create the illusion that Ah Wei was still smoking at 1:25, but in fact,
Ah Wei was killed by Wang Zhe as early as noon."
Lu Weiwei was a little confused when she heard this, and asked weakly: "Junior brother Gu, can you be more specific, what is the situation?"
Gu Chen put on his white gloves, pointed at the astronomical telescope and said, "Sister Lu, do you know the characteristics of the astronomical telescope?"
"Of course I know something about this. Astronomical telescopes can see very far away places, such as the distant starry sky." Lu Weiwei said.
"So, what is its principle?" Gu Chen asked again.
Lu Weiwei suddenly felt a sense of déjà vu like a primary school student being called upon by the teacher, and said blankly: "Because...because of those lenses?"
"That's right." Gu Chen walked to the other side, pointed to the lens of the astronomical telescope and said, "This astronomical telescope made of convex lenses is Wang Zhe's tool for forging the time of Ah Wei's death."
Lu Weiwei was stunned, looked down at the astronomical telescope, and said blankly: "Can this thing fake the time of death?"
Although she had caught up with the idea, Lu Weiwei still didn't react for a while.
"Senior Sister Lu, the reason why we can see far away with the astronomical telescope is mainly due to the lens. The two lenses of the astronomical telescope are both convex lenses. They are thin on both sides and thick in the middle. This can magnify things.
It can also play a role in concentrating light.”
"That's right." After listening to Gu Chen's words, Lu Weiwei seemed to be enlightened and said, "I often played this kind of game when I was a child, using a convex lens to enlarge the fonts."
"I've played with it too." Gu Chen smiled and continued: "The reason why a convex lens can gather light is mainly because the light will be refracted. If it is a parallel light, it is injected into the convex lens, and the light will be reflected on both sides of the lens.
After two refractions, it will be concentrated at one point, that is, concentrated light."
"And when the light is focused on a certain combustible object for a long time, it may cause combustion?" Lu Weiwei finally caught up with Gu Chen's rhythm, feeling that this was the success of the teacher's teaching.
"Senior Sister Lu, do you find it interesting now?" Gu Chen asked.
"You still have to say it? I already know what you want to express."
Lu Weiwei tore off a piece of paper from the notebook and adjusted the angle of the astronomical telescope so that the light could be focused on one point.
After a long time, the edges of the paper began to burn, but not very powerfully.
"Put it down, Senior Sister Lu." Gu Chen smiled, took the astronomical telescope from Lu Weiwei's hand, and said: "The sunlight is not strong now, and the angle is not easy to control, so even if you adjust the angle specially, you may not be able to achieve the desired result.
best effect."
"So the best effect is at noon? The sun is strongest at noon, and if you focus on the cigar, it can light the cigar."
"And this takes time, and it can't be done in one go, so this Wang Zhe must be familiar with the changing time of the sun."
"Senior Sister Lu is right." Gu Chen opened the ashtray, and there was indeed a burnt mark on the wooden board underneath.
"Senior Sister Lu, Wang Zhe has actually discovered a long time ago that if he puts the astronomical telescope in the window, when the afternoon sun shines, he can use the fixed angle of the astronomical telescope on the window sill to focus on one place, thus having the effect of lighting a cigar.
"
"Haha, it's true." Lu Weiwei was quite happy after reading it and said: "It seems that Wang Zhe had already planned to kill his master, so he created some traps to confuse our normal judgment."
Gu Chen also smiled and said: "If I hadn't found out last night that Wang Zhe and Ah Wei were quarreling, maybe I wouldn't have doubted him. But this guy is very scheming. No matter how he covers it up, there will always be some mistakes."
Looking at the black mark on the wooden board on the table, Gu Chen continued: "This black spot is the result of Wang Zhe's experiment, so he also made a fixed mark on the placement of the astronomical telescope."
Lu Weiwei followed Gu Chen's train of thought and carefully examined the location where the astronomical telescope had been set up. Sure enough, she found several small scratches.
Putting the astronomical telescope at the notched position, it was indeed aimed at the burning focus under the ashtray.
"Junior Brother Gu, your judgment is completely correct. It seems that Wang Zhe cannot be cleared."
"That's right." Gu Chen also raised his head and looked out the window and said, "But to have sufficient evidence, we have to wait until the experiment tomorrow to get the results."
"And if we arrange the astronomical telescope according to the position of the small notch, and wait until about 1:25 noon, the light can be focused on the burnt position on the wooden table, then we can determine the time of death of the deceased Ah Wei.
It might not be after 1:25, and if you add in forensic doctor Liu’s judgment, it’s probably close to ten.”
"Yes, forensic doctor Liu may have a certain error in determining the time of death, but if this kind of experiment is used to determine that it was around 1:25 and the cigar could be lit, then it will be useless no matter how many lies this guy Wang Zhe tells."
Thinking of this, Lu Weiwei suddenly felt that Wang Zhe's previous performances were really full of loopholes.
