January 23, 2016, the fourteenth day of the lunar month.

Early in the morning, the teams of the three major teams were gathered, and they all gathered in Nobita's office.

According to last night's arrangement, I watched the surveillance video at Nobita's place today, and then confirmed the four people who ate hot pot in a private room with Guo Jinming. Master the physical characteristics of five people, including Guo Jinming, and then track them.

Actually, Guo Jinming's physical characteristics don't need to watch the video, because Shangguan Keke and Youhua remember, Guo Jinming went to their private room (Hulunbuir) and showed his face on the night of eating hot pot. So Shangguan Keke and Youhua recommended themselves, and they went to check Guo Jinming's traces.

At that time, who was with Guo Jinming, the thin man who met Yao Zhenhua in the bathroom was handed over to Liu Yan to follow.

There are three people in the private room, and it can be seen through the monitoring that there is a man who is not tall, about 1.65 meters, he is bald, he is wearing a peaked cap when he goes out, he can't see his face clearly, he walks outside the figure, his clothes are dark, and there are no obvious features.

There is also a woman, like a middle-aged woman, because she has long hair and a scarf, so she can't see her face clearly, but she is thinner, about one meter six tall, and she is carrying a yellow-colored lady's bag, and this woman is also handed over to Shangguan Keke and Youhua to track.

There was the last person, he was a middle-aged man about 1.8 meters tall, between forty and fifty-five years old, with short hair, a pair of large black-framed glasses, a black trench coat, and a black fleece glove, and the man was handed over to Nobita to follow.

"Team Yao, what should I do?" Hao Chunxiao asked Yao Zhenhua.

"You and I go with you to Persimmon Mountain Psychiatric Hospital, you go and prepare the procedures for the hospital, and we will investigate there." "Regarding the murder of Wang Tao, the Money Bureau asked our three teams and the second team to work together to solve the case as soon as possible, so we have a case." Yao Zhenhua said it very easily, everyone knows that this case is too difficult to solve.

"Team Yao, is this an old bone?" Liu Dong joked.

"Yes, it's an almost year-old bone, and almost all the clues are broken." Yao Zhenhua followed Liu Dong's words and made it clear to everyone the difficulties of the case.

Everyone is a little confused, which case is to be handled now, or which case is the focus.

Yao Zhenhua added: "Guo Jinming's case is a case that our brigade will handle in the future, and I speculate that Guo Jinming has too many secrets behind it, and his secrets may bring us a big case." "The Wang Tao case is the first case handled by our team, so for our three teams, its historical significance is very important."

The people who received the task heard Yao Zhenhua's explanation and went to work. Hao Chunxiao is ready to go to the psychiatric hospital.

Yao Zhenhua returned to his office, took himself to the police officer card, and prepared to set off to the Persimmon Mountain Psychiatric Hospital.

Yao Zhenhua drove the newly received official police car, and the road was very smooth, so he quickly arrived at Persimmon Mountain Psychiatric Hospital.

Persimmon Mountain Psychiatric Hospital, located near the city, more than 20 kilometers away from the central city, is located on the top of Persimmon Mountain.

This is a tertiary hospital, and the hospital is fully equipped with various equipment and staff. The entrance is made of iron plates, and you can't see the inside from the outside.

Yao Zhenhua drove the car to the gate, and Hao Chunxiao went to the doorman to register.

After registration, the door of the hospital suddenly opened, and there was a squeaky and chirping sound.

The car drove in, and Yao Zhenhua found that it was divided into two isolated courtyards.

On the left is the office area, as the security guard has just said, foreign vehicles can only drive into the left.

On the right is the inpatient treatment area.

After they entered the gate of the Persimmon Mountain Psychiatric Hospital, a very young doctor came, and after introduction, they learned that this young doctor turned out to be their vice president, whose name was Liu Hongde, who was not tall, of standard size, wearing leather shoes and a white coat, with sparse and short hair, and a pair of big eyes that were embarrassed. This is because Yao Zhenhua called the hospital in advance.

"Officer Yao, Officer Hao, hello." Vice President Liu Hongde greeted them warmly.

"Hello President Liu, we came to your hospital to investigate a murder case, the victim's name is Wang Tao, this Wang Tao was still here last year to treat mental illness, but unfortunately he was killed on the evening of Chinese New Year's Eve last year." After Yao Zhenhua said hello, he directly explained his intention to Dean Liu.

Hao Chunxiao submitted the formalities, and Dean Liu led them to his office. Said very politely: "Officer Yao, how do you need us to cooperate with you?" ”

"Thank you, Dean Liu. We want to see the surveillance video of Wang Tao during his hospitalization? ”

"The surveillance video, we have handed it over to the police at that time, we did not keep a backup here, because the amount of data is very large, we cannot save it completely, so we only save the surveillance video from half a year ago."

"Oh, that's it." Yao Zhenhua paused for a moment, and then said, "I want to know something about the situation with Wang Tao's attending doctor." ”

"Okay, I've informed him, I'll be there in a moment." Dean Liu replied.

In fact, this Dean Liu has already figured out the investigation procedures, because he received the people from the second team last time they came to investigate.

About a quarter of an hour passed.

A tall and burly male doctor came in, also wearing a white coat, leather shoes, and a stethoscope in his hand, presumably having just examined the patient's body.

The doctor asked a little unhappily, "Dean Liu, are these two police officers?" ”

"Yes." Dean Liu replied.

Yao Zhenhua and Hao Chunxiao stood up and shook hands with the doctor.

"Officers, please hurry, because I still have patients waiting for me to check them out." Wang Tao's doctor once again let out an impatient tone.

"Okay." Yao Zhenhua replied, "Thank you, doctor. What do you call you? ”

"My name is Yan Zhixue." Another impatient answer.

"Hello Dr. Yan, I would like to know what state Wang Tao was in when he first entered the hospital? The first time you received him for examination and treatment, how did you judge him? Yao Zhenhua began to ask.

"Wang Tao, a patient, was about to have a mental breakdown when he first arrived, and he was very frightened, and I could see it in his eyes. In the next few weeks, we found that Wang Tao did have some mental problems, but it was not to the extent that he had to be hospitalized, and we suggested that he should be hospitalized at home, and he claimed that he had to be hospitalized, and wanted to end the treatment as soon as possible, recover his health, and return to his normal life. ”

"Finally,...... (Some words are omitted here). Dr. Yan glanced at Dean Liu and said, "Wang Tao was hospitalized for about half a year. ”

"You mean, Wang Tao himself asked for hospitalization?" Yao Zhenhua asked.

"That's probably what it means." Dr. Yan replied.

"During the hospitalization, did Wang Tao tell you why he was hospitalized? Why the fear? ”

"I didn't say this, but I checked his body and found that after a few months of hospitalization, his physical and mental state is really good, and he is no different from a normal person."

"Who visited Wang Tao during his hospitalization? Does your hospital have a record? After Yao Zhenhua finished asking this question, he looked at Dr. Yan and Dean Liu.

Dean Liu replied, "We have a record, you can check it later." After speaking, Dean Liu called the hospital staff and asked them to bring the registration form for last year's visit.

Dr. Yan asked, "Still have questions?" ”

"No problem for the time being, Dr. Yan, thank you!" Yao Zhenhua expressed his gratitude to Dr. Yan.

Yao Zhenhua and Hao Chunxiao reviewed the record form of Wang Tao together, and found that the vast majority of the visitors were his relatives, except for one time, it was two people, and the two names showed that they were not Wang Tao's relatives, one was called Lu San and the other was Wang Bo.

After Yao Zhenhua saw it, he concluded that the identity information of these two people was all fake, and after Hao Chunxiao's inquiry, his inference was confirmed.

"Wang Tao, you are too suspicious!" Yao Zhenhua thought to himself.

There is nothing to be gained in the Persimmon Mountain Psychiatric Hospital, and it seems that there will be no gain from direct investigation, because at that time, everything that the second team could investigate was investigated, and if there were any clues, they would have found out and used them a long time ago.

The bamboo basket is empty, and there is only "going home".

Yao Zhenhua and Hao Chunxiao said goodbye to Dean Liu, went out of the office building, and saw the cold building in the inpatient area for the mentally ill next to them, and they really felt like a different world. In such an environment, it is incredible that Wang Tao has become normal after moving in.
