"Can speak three Chinese languages?" Listening to Dean Zou's introduction, Gu Chen fell into deep thought: "Knowing three Chinese languages, thinking about it is not something that ordinary people can do, does this person have any ulterior secrets?"

Although Gu Chen had no experience in dealing with mentally ill patients, he could feel that any patient who entered a psychiatric hospital for treatment must have been strongly stimulated before.

Thinking of the practice of those who often hurt people in TV reports, family members issued a certificate of mental illness from the hospital to avoid heavy punishment, Gu Chen still knew.

"Regardless of whether these people have encountered something that they cannot decide, escaping from the psychiatric hospital is also a serious threat to the outside world, because these people are not qualified to be discharged, and if they are not found as soon as possible, they may cause harm to others. ”

The middle-aged woman in a white coat on the side has considerable experience in the contact with the mentally ill, so she also gave pertinent advice.

"Comrade policeman, this can be said to be a negligence in the management of our mental health center, but if a patient really wants to do bad things outside, it will be troublesome. ”

Dean Zou was also anxious at the moment......

It can be seen from his practice of asking the security guard to bring the police to the office as soon as possible that Dean Zou is really in a hurry.

"Don't worry, take us to the monitoring room first. Officer Wang said.

"Okay, you come with me. Dean Zou didn't dare to slack off, and personally took everyone to the monitoring room.

In the surveillance footage, the cooperation of the four men is indeed in place.

If it weren't for careful identification, or if it was known in advance that the four people were mentally ill, there would be no difference at all.

"Is this too smart, and you are in good spirits?" Lu Weiwei couldn't help but sigh when she looked at the picture of the four of them running wildly all the way after they left.

"This state is smarter than normal people. Officer Wang couldn't help but sigh twice and complained: "This mentally ill person can speak three Chinese, so what are we?"

"I guess it's too guilty in there, right?" Gu Chen looked at Lu Weiwei and Officer Wang, and said, "It's just that the worldview is different, and there is a line between geniuses and madmen." ”

"I feel like if I don't work hard, maybe I'm not as mentally ill. Lu Weiwei suddenly felt a serious sense of frustration.

Gu Chen said to the staff: "Is there any surveillance footage of these people a few days ago?" ”

"Yes...... Some. The staff nodded and said, "The surveillance footage on our side used to be kept for half a month, but now it is kept for a week." ”

"Tune it out. Gu Chen said.

The staff looked at Dean Zou beside him.

"Listen to Comrade Police. Dean Zou also said.

"Okay, it's a bit of a lot of work, why don't you sit down and wait first. After a brief explanation, the staff hurriedly operated the mouse and keyboard and began to query the monitoring footage of the four people in recent days.

Gu Chen, Lu Weiwei, Officer Wang, and Dean Zou stood aside and waited patiently.

"Senior Brother Wang, these people are monitoring outside, can we also cooperate with the dispatch room?" Gu Chen asked.

Officer Wang nodded: "This is no problem, I'll make a phone call and pass on the information of these people and let them check it carefully." ”

After finishing speaking, Officer Wang took the photos and files of the four people with his mobile phone and sent them to the old comrades in the dispatch room, asking these people to cooperate in the search for the whereabouts of the four people.

"Dean Wrinkle. Seeing that the surveillance outside was being pursued, Gu Chen turned around and asked Dean Zou beside him: "Can you call the security guard who was derelict today, I want to ask about the situation." ”

"This ...... That's fine, you wait. Dean Zou also took out his mobile phone, dialed a number, and quickly explained a few words on the phone, and then hung up the phone.

Not long after, a tall and thin man about fifty years old walked quickly to the monitoring room.

The moment he stepped through the door, the man suddenly slowed down and looked inside.

Seeing that the police were there, he walked into the room in small steps.

"Zou Yuanzi, are you looking for me?" the man said.

"It's not me looking for you, it's the police looking for you. "Dean Zou is also not angry now.

The man's mistake caused the mentally ill to flee in a group, which in itself was a very fatal thing.

"Don't be nervous, come in and sit. Gu Chen took out a stool and put it next to the security guard.

After the security guard sat down, his hands were also clasped tightly, and he did not dare to look directly at the police.

"What's your name, report your ID number. Gu Chen picked up the notebook and began to record according to the process.

"I ...... My name is Zhang Gencai and my ID number is ......"

The security guard named Zhang Gencai was obviously a little nervous, and he was also slurring when he spoke.

"When the four of them left, were you on duty?" Gu Chen asked.

"Yes...... Yes. ”

"What were you doing?"

"I was eating, I just got food from the cafeteria. ”

"Then why did you let them go? Don't you know...... Do I have to have an approval signed by Dean Zou to leave?"

Gu Chen put down his pen and looked up at Zhang Gencai.

"I'm ......" The man stopped talking, looked at Dean Zou innocently, and said, "I didn't think much about it at the time, looking at these four people like family members coming to pick up patients and discharge them." ”

"So you didn't ask for the approval slip and just let them go?" Gu Chen asked.

"Also...... Neither is it. Zhang Gencai silently lowered his head and said helplessly: "I was eating at the time, and I was about to ask them for approval, but at this time, the phone at the security booth came up, so I went to answer the phone first." ”

"You should check the slip before you answer the phone. Lu Weiwei corrected Zhang Gencai's wrong approach.

"You're right to criticize. Zhang Gencai did not deny it, nodded, but said: "But to get out of that iron gate, you need to take the key from me, I didn't pay attention at the time, but after answering the phone, I found that several people suddenly disappeared." ”

Gu Chen suddenly looked back at Lu Weiwei and Officer Wang, and they all felt that something was wrong.

"In other words, to leave the small door of the inpatient building, I need to get the key from you?" Gu Chen asked.

"yes, yes, I wasn't eating, and then I took another phone call, and the attention wasn't on the four of them. ”

But when I put down the phone and went to look at the four people, I found that they were all gone, and I thought that these people must have forgotten to take the slip, and then I went back to look for the slip. ”

"But what I didn't expect was that it didn't take long for the comrades in the hospital to hear that four mentally ill people had escaped from the health center, and I panicked because they said they had escaped from my side. ”

After listening to Zhang Gencai's story, Gu Chen couldn't help asking, "Could it be that these mentally ill people took the key from your security booth?"

"Not really. Zhang Gencai shook his head and said, "The key to my side has always been there." ”

"That is, they used another key to open the small door of the inpatient department, and then escaped en masse?" Lu Weiwei was also quite shocked.

I feel that these guys are either crazy or geniuses, no wonder they say that crazy people and geniuses are in the same thought.

Maybe they're in the wrong place, or maybe they're out mischievous for a while?

The saying that talents are in mental hospitals is indeed true.

"Yes, female officer, they really didn't use my key to open the door, and if I hadn't received a call at the time, probably they wouldn't have been able to leave. ”

Zhang Gencai also clarified with great certainty.

At first, Gu Chen and most people thought that it was the negligence of the security guards that caused the patients to flee from the psychiatric hospital.

But now the information obtained from Zhang Gencai's mouth can be fully proven.

These mentally ill people apparently got the key to the small door of the inpatient building first, and then implemented the escape plan.

All the steps were smooth and seemed to be very smooth.

If noon is the perfect reality to escape from a psychiatric hospital, then did these people steal the key themselves? Or did someone deliberately give it to them?

If that's nothing, the phone that happens to ring at this time is God's assist.

"By the way, who made that call?" Gu Chen put aside his temporary thoughts and raised his head to ask Zhang Gencai.

"I don't know. ”

"You...... You don't know either?" Gu Chen was surprised.

"Yes, I don't know, because there was no one talking on this phone, maybe there was something wrong with the phone, I looked at the caller ID, it was an unfamiliar number. ”

The scene suddenly fell into a short silence, Gu Chen did not ask questions immediately, but sorted out his previous thoughts.

"In other words, these four mentally ill people, disguised as discharged patients, and the patient's family, and then they still have the key to the small door of the inpatient building, and it is precisely when they come to you that a phone call distracts your energy, which caused the successful escape of these four mentally ill patients, right?"

Gu Chen quickly finished writing the information he had sorted out, and looked up at Zhang Gencai.

"That's it. Zhang Gencai nodded and did not deny it.

As soon as Gu Chen threw away the pen, Lu Weiwei beside him said directly: "There must be something wrong with this, all the escape steps feel like they have been coordinated." ”

"I think so too. Officer Wang, who was listening carefully, also said: "On the surface, it seems that this is an incident of a mentally ill person fleeing because of the negligence of a security guard." ”

"But after careful analysis, it is not difficult to see that there seems to be a master behind the scenes, including the disguise of the four people, as well as the accurate grasp of the time when they came to the door, and the mysterious phone call?"

"Huh. Dean Zou also couldn't help laughing twice, and said, "I said comrade police, do you usually handle a lot of cases, and you want to be premeditated when you see everything?"

Gu Chen stared at him and said, "Isn't it?"

"Isn't this just an ordinary case? Four mentally ill people escaped from the psychiatric hospital, but the key may have been stolen by these four mentally ill patients, and the phone call just happened to be an advertisement. ”

"Wait. Gu Chen didn't let Dean Zou finish his words, and directly interrupted: "How many keys are there to the small door of the inpatient building, and who are they in?"

"This ......" Zou Yuanzi was suddenly stunned.

"You say. Gu Chen looked at Zhang Gencai and said, "Who else but you?"

"In addition to the duty room, there will be two in the hands of the leaders of the hospital, one in the hands of Director Liu, and one ......"

Zhang Gencai stopped talking and looked at Dean Zou silently.

"Who else is in someone's hands?" Lu Weiwei also hurriedly asked.

"Also...... There is another handful, in the hands of Dean Zou. ”

Zhang Gencai said it very quietly, but Dean Zou panicked and said directly: "Comrade policeman, the keys stolen by these four mentally ill patients are definitely not in my hands." ”

"Then since it's not the key to the security room, it's either Director Liu's or your Dean Zou's. Officer Wang didn't talk nonsense, and said directly: "Trouble Dean Zou, go find Director Liu, and ask him to bring the key to the small door of the inpatient building." ”

"Alas!" Dean Zou responded in front of him, took out his mobile phone and dialed Director Liu's phone.

It didn't take long for a middle-aged man with a fat figure to walk into the monitoring room with his glasses.

"Are you Director Liu?" asked Gu Chen.

"Yes. The chubby man nodded.

"Did you bring the key to the small building in the inpatient department?" Gu Chen asked again.

Director Liu took out a bunch of keys from his belt buckle, picked out one of them, and handed it to Gu Chen: "This is the key to the small door of the inpatient building, what's wrong?"

The atmosphere at the scene was tense again.

Gu Chen didn't answer immediately, but glanced at the courtyard of Zou beside him.

At this moment, not only Gu Chen, but almost everyone's eyes were looking at Dean Zou.

Security guard Zhang Gencai was stunned and said, "Zou ...... Dean Zou, Director Liu and I didn't lose this key, so I shouldn't lose it...... It's yours, right?"

Dean Zou was quite embarrassed at the moment, and his face stiffened for a long time before he said, "Okay, I admit that the lost key is indeed the one on my body." ”

"Oh my God. Lu Weiwei exclaimed: "It turns out that the keys used by these four mentally ill patients to escape are actually your Dean Zou's." ”

"Don't ...... Don't get me wrong. When Zou Yuan saw the three policemen and the colleagues at the scene, they all looked at him with questioning eyes, and couldn't help but panic: "I'll tell you the truth, I lost this key three days ago." ”

"At that time, I thought I had forgotten somewhere, so I searched for a long time, but I couldn't find anything, so I panicked. ”

"After all, this is the key that manages the small door of the inpatient building, and if you lose it, it will be troublesome. ”

"Then why didn't you tell us about this situation earlier?" Gu Chen asked.

"I ...... I'm not afraid of responsibility. Dean Zou also said with a frustrated face: "I have only been the dean for a few days, and I want others to know that I lost such an important key, so these other people who have been staring at the dean's position will not give me a small report?"

"But since this problem has happened, you should make up for it in time, but in the past three days, you haven't made any statement, just get by, to be honest, Dean Zou, your style is not very good. ”

Listening to Officer Wang's criticism, Dean Zou also hurriedly bowed his head and said: "That's right, what the police comrades have taught is that it is my negligence in my work and my lack of vigilance, and after this time, I will definitely self-examine." ”

Hearing this, Zhang Gencai on the side patted his chest with relief, and said that he was scared to death just now, and he worked together for a long time, and the key turned out to be lost by your Dean Zou, and he almost made you a backstabber.

After getting rid of these burdens, the tone of the security guard Zhang Gencai's speech was obviously very different from before.

It's not whispering anymore......

"Dean Zou, the surveillance footage has been found. ”

At this time, the staff in the monitoring room also came with good news.

Dean Zou and everyone hurriedly stepped forward to check the relevant monitoring of the four mentally ill patients in the past few days.

The first video played by the staff was when they woke up this morning.

According to the information file provided by Dean Zou just now, Gu Chen quickly discovered the first mentally ill person.

"Huh, how can it be a person?" Gu Chen asked curiously, "Could it be that they usually live in different rooms?"

"Yes. Director Liu on the side replied: "These people all live in different wards, and they only get together when they eat and move. ”

Gu Chen didn't dwell too much, and directly ordered the staff: "Play the second paragraph as well." ”

The second video is the picture of these mentally ill patients, after getting up, walking into the hospital cafeteria one after another.

As can be seen from the picture, after the four of them arrived at the cafeteria, they were not in the same location.

But later, when the last patient arrived, the other three patients who arrived first took the initiative to take the breakfast and walked to the patient's side.

The four of them formed a small group, bowing their heads and whispering from time to time, feeling like they were plotting something important.

"Stop!" Gu Chen suddenly shouted to stop.

The staff hurriedly pressed a pause button.

At this moment, Gu Chen suddenly blinked twice quickly.

With a "click" of photographic sound in his mind, Gu Chen quickly freeze-frame and analyzed this picture with the primary visual cutting function.

Soon, in the visual interface, two options appeared: store and analyze.

Gu Chen chose to analyze without hesitation......

Soon he found that in the surveillance screen, one of the patients took out the things, and the analysis results were: 70% were keys, 20% were cutlery, 5% were accessories, and another 5% were others.

"What's wrong Gu Chen?" Lu Weiwei saw that Gu Chen had been staring at the surveillance screen for a long time, but there was no movement for a long time, so she couldn't help but ask him.

"The thing these people are holding in their hands should be the key to the small door of the inpatient building. Gu Chen said.

"Can you see this?" said Officer Wang, a little incredulous.

He hurried up, looked left and right, looked up and down at the surveillance screen, but in the end he still didn't find anything.

"Gu Chen, can your eyesight be so good? This picture is not very clear. Officer Wang was shocked and said, "How can I see such a small item as a key with the naked eye?"

Of course, Gu Chen would not tell Officer Wang that his eyes have a visual cutting function, and he can carry out automatic analysis on the function of screenshots to judge the type of items from the probability.

This thing is not easy to explain, Gu Chen did not answer Officer Wang's question, but directly changed the topic and said: "If the key is already in the hands of these four psychopaths at this time, the time to lose the key is definitely not today." ”

Looking at the staff, Gu Chen said again: "Come, trouble this little brother...... Bring up yesterday's video again. ”

......
