Zhang Jingde is now faced with a dilemma. On the one hand, the two security guards have confirmed their confessions, and on the other hand, the man in the suit, Zhang Xiaogui, has firmly denied it.
If the so-called murder weapon can be found in the office, then even if Zhang Xiaogui tries to quibble, there will still be no flaws.
"Comrade police." Zhang Xiaogui said weakly: "I was really wronged. You can't just believe their words."
"You mean, these two security guys are lying?" In Gu Chen's impression, the two security guys seemed like honest people, but Zhang Xiaogui was a bit glib.
But of course Gu Chen also knew that you should never judge people by their appearance, and Zhang Feng of the Railway Workers Theater is the best proof.
Criminals often, in order to clear their charges, have their inner universe suddenly explode when facing police questioning, and it is not uncommon for their acting skills to explode.
One of the security guards who was bitten by Zhang Xiaogui immediately said angrily: "You are simply slandering others. You are obviously suspected of injuring the manager, but you are still here pretending to be innocent. I...I really want to beat you."
The security guard was so angry at Zhang Xiaogui's words that he almost stamped his feet, rolled up his sleeves and looked like he was going to fight with him.
Zhang Jingde and another security guard quickly stopped him.
"Everyone, stop it. Before the case is investigated clearly, you must be responsible for everything you say. Once you find out who is lying, it will be an additional crime. It is not too late to confess now."
Zhang Jingde is a veteran comrade who has been in the police for many years, and he has seen many such arguments where both sides hold different opinions.
In his opinion, testimony must have definite evidence.
He turned around and asked the security guard who was bitten just now: "Is there any surveillance in this passage of your mall?"
"Yes." The security boy suddenly realized: "Yes, there is surveillance here. You will know if you call the surveillance."
Everyone's eyes were focused on Zhang Xiaogui at this moment, but this guy said with an innocent face: "You want to adjust the monitoring, whatever."
In the monitoring room, an operator was playing the video playback, but camera No. 15 showed a black screen.
"What's going on?" Zhang Jingde frowned: "Your equipment is not usually inspected?"
"They know how to repair it. If it's broken, just fix it." The operator was also confused. After thinking for a while, he said: "I took a day off yesterday and it was my colleague's shift. Comrade policeman, please wait a moment and I'll ask my colleague.
.”
Then the operator picked up the mobile phone and dialed the number. Amidst a burst of chattering beeps, the operator hung up the phone in distress.
"Comrade Police, my colleague said that camera No. 15 was broken during off-duty hours yesterday. It happened that the maintenance technician did not work overtime, so I never had time to repair it. I'm really sorry."
Seeing that he could not help the police, the operator looked guilty and apologized profusely.
"Forget it." Zhang Jingde looked disappointed and said to Gu Chen, "How about we go back and look for it? Maybe there is something missing."
"Okay, I'll listen to Uncle Zhang." Gu Chen was also happy. He still had to help Comrade Zhang Jingde to some extent.
Then, another full hour passed.
Gu Chen even dismantled the ceiling to check, but still could not find the so-called murder weapon.
Five people in the entire office, including the two security guards who had just captured Zhang Xiaogui, rummaged through the boxes and cabinets, but still found nothing.
Now Zhang Xiaogui said impatiently: "Comrade police, you just arrest people without any evidence. Isn't that not good? I have already said that I happened to enter the office, but I happened to find the mall manager lying on the ground.
I ran out in a hurry, but these two security guards insisted that I was the culprit. Who the hell am I trying to reason with? Am I still being reasonable?"
"Shut up." Zhang Jingde was very annoyed now, and he began to waver in his previous judgment.
Could it be that the perpetrator was not Zhang Xiaogui?
He turned to look at Gu Chen and asked, "Xiao Gu, I want to hear your opinion."
"Let me think."
Gu Chen was currently drawing the floor plan of the entire office in his notebook. When he was interrupted by Zhang Jingde, he also said flatly: "Based on the floor plan of the scene, it is unrealistic to throw the murder weapon out of the window."
Gu Chen had tasted the benefits of solving crimes through the window several times before, so today he repeatedly studied the integrated window, including the possibility of replacing the glass.
However, for this special closed floor-to-ceiling window, all the glass glues are intact.
Besides, the two security guys heard the mall manager’s screams and rushed over without stopping.
Even if Zhang Xiaogui has great magical powers, he cannot hide them in a very short period of time.
"That's right." Gu Chen's eyes suddenly lit up, and a master-level logical reasoning in his mind suddenly popped up a keyword: time of crime.
"How long did it take from the time you heard the mall manager's scream to the time you captured Zhang Xiaogui?"
"One minute?" the bitten security guard hesitated.
"No, it didn't take that long." Another security guard raised a new question: "It should be forty seconds at most."
"How long is it?" Zhang Jingde was a little impatient. The two people's answers were very different.
"How about this." Gu Chen suddenly had a new idea: "We can simulate the situation just now. I will call you. After you hear my instructions, you will quickly run to the door from where you were just now. I will be responsible.
Time."
"Hey! I think this method is good." Zhang Jingde also clapped his hands and applauded: "In this way, we can get accurate data."
The two security guys looked at each other and nodded in agreement.
"That's okay."
"You just wait here."
Gu Chen took the cell phone of one security guard and then dialed the number of another security guard.
Then, Gu Chen said: "Start."
The two security guards, according to Gu Chen's request just now, began to simulate hearing the phone call, then locked their eyes on the office door, and then truly restored the scene between them.
When the two arrived at the door of the fifth floor office, Gu Chen decisively pressed the stopwatch: "Thirty-five seconds two-two."
The results are finally out.
"In such a short time?" Zhang Jingde was also stunned, then turned to look at Zhang Xiaogui: "If no one enters or exits the office, then you should be the suspect suspected of attacking the mall manager."
Zhang Xiaogui was also panicked and quickly defended: "But...but I don't have the murder weapon at all, so what do you say?"
The bitten security guard said angrily: "If I find the murder weapon, I won't blow your head off, and I'll let you taste the feeling of having your head smashed."
"Don't get excited." Zhang Jingde once again tried to persuade both parties to make peace.
At this time, the apprentice Comrade Xiao Li asked weakly: "Master, could it be Zhang Xiaogui? Didn't he use a weapon like a steel rod? For example, use a teacup or a stool or something like that?"
"Impossible." Before Zhang Jingde could reply, Gu Chen was the first to deny it.
"Why?" Comrade Xiao Li was puzzled: "Am I right?"
"Senior Brother Li's idea is right, but..." Gu Chen hesitated, thought for a few seconds and then said: "But I just checked all the items that may be used as murder weapons. If it is a teacup, in this case,
Under the impact, there will definitely be fragments. If it is a stool, it must be at the sharp corner of the stool, otherwise there will be no such power at all."
Gu Chen has entry-level observation skills, and these small details cannot escape his eyes.
Obviously, what Comrade Li just mentioned are not murder weapons.
"That's not true, that's not true either. Are you trying to kill people?" Comrade Xiao Li also looked depressed when his opinion was rejected.
However, at this moment, Gu Chen suddenly thought of a new doubt: "By the way, I seemed to have missed one of the most critical points just now."
