The group of the serious crime team came to the psychiatric hospital to investigate, and He Jiahui also followed.

Arriving at the scene of the crime, Ho Ka-fai first observed the surrounding environment.

Yang Lixin is the murderer of the serial murder case, which is a felon, and even when he is receiving treatment, he is locked up in a single room.

There are no windows in the studios, there are vents in the ceiling, and there is an observation opening in the door to see inside. In other words, only through the door can you reach the people inside.

He Jiahui looked at the deceased on the bed again, it was indeed Yang Lixin.

Yang Lixin's hand was on his chest, his body curled up slightly, and the expression on his face was distorted, looking like he was in pain before he died.

"It doesn't look like he's without trauma! With his hands on his chest and a painful expression, it is likely that there is a heart problem and sudden death. ”

He Jiahui said, looked at the director of the mental hospital, and asked, "Your patients here all have to undergo a physical examination before they are admitted in, right?" Does Yang Lixin have any physical problems? ”

The dean shook his head decisively: "I have already brought the physical examination report of this patient when he was admitted to the hospital, and his body is very healthy, and there is no problem with his heart." ”

"What about your medications? Could it be a side effect of the drug? He Jiahui asked again.

"We strictly follow the doctor's instructions when we give drugs to our patients. And according to the psychiatric evaluation report, the patient's condition is not serious, and there is no need to use strong tranquilizers, and there should be no serious side effects. The dean replied immediately.

He Jiahui nodded, and then said: "If there is no problem with the patient's body and there is no problem with the hospital's medication, then Yang Lixin is very likely to die of poisoning!" ”

"Poisoned?" Ma Jun next to him continued: "Before the patient comes in, he must not bring his personal belongings, Yang Lixin is a repeat offender, and he will be carefully examined, it is impossible for him to bring poison in."

Moreover, Yang Lixin's lawyer made the trick that he had mental problems, which also shows that Yang Lixin should have a relatively strong desire to survive, and he does not want to die. If it was poisoning, then it is highly likely that he died of murder. ”

He Jiahui then asked: "Dean, do the other patients have any physical discomfort or other abnormal manifestations?" ”

The dean thought for a moment and replied, "I didn't find any patients who were unwell, as for the abnormal behavior, this is a mental hospital, and the patients who were sent here are not performing normally." ”

"The other patients are fine, only Yang Lixin was poisoned and died, which should be a murder specifically aimed at him." He Jiahui then asked, "Dean, who came into contact with the deceased yesterday?" ”

"Well, I'm afraid there are quite a few. Doctors, nurses, nurses, cleaners, patients, it is possible that they have come into contact with him. The dean paused, then said:

"Sir, let me introduce you to our schedule here. Every morning at 6:30 a.m., the wake-up bell rings, and from 6:30 to 7:30 is the time to wash, and at the same time, we play soothing music throughout the hospital to help patients calm down.

After washing up at half past seven, it is time for breakfast, and all patients will go to the cafeteria for breakfast, after which they will return to their rooms. After that, we will give the patient medicine and let the patient take it. This process usually lasts after half past eight.

At nine o'clock, the doctor begins his rounds, which usually last an hour. At ten o'clock, a snack is distributed to the patient.

From 10 o'clock to 11 o'clock, it is free time, patients can stay in the room, or they can go to the activity room to play cards, go to the entertainment room to watch TV, and go to the library to read books and newspapers.

At 11 o'clock in the morning, there will be a second dose of medicine, lunch will start at half past eleven, and after lunch, it will still be free time until five o'clock in the afternoon.

We will give out fruit once during this time, around 2 pm and 3 pm. After 5 p.m., it's time for dinner, and after dinner, it's free time.

At eight o'clock in the evening, all the patients return to their rooms, and then the nurse will go to the various wards, count the number of people, and at the same time give the patients medicine and take the medicine, and the patient can rest after taking the medicine. ”

"Is Yang Lixin's schedule like this?" He Jiahui immediately asked.

"This is how everyone else is managed, except for those who are unable to take care of themselves and who are violent and self-harming. For patients with violent and self-injurious behavior, we fear that they will limit their mobility by injuring other patients or by injuring themselves. The dean replied.

"Yang Lixin is the murderer of a serial murder, he killed four people, don't you worry about him and other patients together?" He Jiahui asked again.

"In Stanley Prison, aren't the prisoners who have been imprisoned for life also locked up with other prisoners?" The dean paused, and then said:

"This patient is self-reliant, and he is in a good mental state, he is not showing violence or self-harm, we can't restrict his movements, all we can do is give him a separate room."

He Jiahui sighed a little helplessly, just these few hours of free activity every day, Yang Lixin can come into contact with a large group of people, which is equivalent to investigating the murderer in the entire mental hospital.

"It's a complicated project for so many people to investigate!" Thinking of this, He Jiahui opened his mouth and said; "Director, we need information on all the staff and patients in the hospital, as well as the visitors who came yesterday."

The dean thought for a while, nodded and replied, "Yes, but there are a lot of people involved, so you need to give me a day to prepare." ”

……

Ma Jun took the forensic report and came to He Jiahui.

"The forensic doctor has already concluded that Yang Lixin was indeed poisoned to death. To be precise, a compound that inhibits the central nervous system and causes cardiac arrest. Ma Jun said.

"That said, it's not a common poison." He Jiahui's brows furrowed slightly.

Common sources of poison mainly include pesticides, insecticides, rat poison, cyanide, arsenide, and poisonous plants. In addition, overdose or injection of drugs can also cause death.

When investigating poisoning cases, finding the source of poison can often bring a lot of clues, and even solve the case directly.

And this time, the poison in Yang Lixin is obviously not a common poison on the market. I don't even know what kind of poison is in the deceased, let alone find the source of the poison, which undoubtedly increases the difficulty of solving the case.

"It seems that only the most traditional methods can be used to screen the personnel of the psychiatric hospital!" He Jiahui said helplessly.

"This is a big project, and there are more than 500 people in total. If our group is screened one by one, it will take many days, and you will have to come and help. Ma Jun said.

He Jiahui pondered for a moment and said, "When patients are admitted to the hospital, they are generally not allowed to bring personal belongings, and it is unlikely that they will bring poison in, so you can leave them alone for now."

The staff doesn't work every day, and there will definitely be people off duty yesterday, so let's start with the people who went to work yesterday. If you add in the people who came to visit yesterday, the scope will be much narrower.

With Yang Lixin's current situation, it is impossible to kill for wealth and love, so the murderer poisoning him must be a vendetta. And this will be divided into two possibilities, the enemy will do it directly, or the enemy will buy the murder.

If the enemy buys the murderer, then the murderer will inevitably get an unsolicited amount of money, and we need to monitor who in the psychiatric hospital has started spending money lavishly.

And if the Qiu family does it directly, it will be divided into two situations, one is that the Qiu family was originally in this mental hospital, and the deceased was admitted to this mental hospital, which just gave him the opportunity to start.

The second is that in order to take revenge, the enemy family specially entered this psychiatric hospital, and then waited for an opportunity to poison the deceased to death. Let's take a look at who came to the psychiatric hospital later than the deceased! ”

In just a few minutes, He Jiahui determined the direction of the limited investigation.

Fortunately, Ho Ka-fai's investigation was in the right direction, and the serious crime team soon found the suspicious person.

"There were two cleaners who were hired after the deceased was admitted to a psychiatric hospital. One of them, guess who? Ma Jun asked.

He Jiahui didn't think about it, and replied directly: "Is it the relatives of the victims in the Naruto murder case?" ”

"So you've already guessed it?" Ma Jun asked in some surprise.

"I said it all, it's a vendetta. There is only a deep hatred for Yang Lixin, and the only ones who have a deep hatred are the relatives of the four victims. He Jiahui paused, and then said:

"Among the four victims, three were students of Chinese University, and those who were admitted to Chinese University must have been pinned on by their families, but they were suddenly killed, and their families could not resent!" The parents of the deceased, in particular, had an absolute motive to kill.

So I think it's more likely that the families of these three victims will do it. As for the director of the property management office, he left behind a minor daughter, and his family still has to take care of this child, so he should not kill anyone. ”

"You guessed it right again!" Commander Ma sighed and continued; "The suspect we found is named Wu Meiqi, and she is the mother of Fang Moxuan, the vice president of students!

After Yang Lixin was imprisoned in a psychiatric hospital, Wu Meiqi came to apply for a job as a cleaner in a mental hospital, she should have wanted to find an opportunity to get close to Yang Lixin and then poison him to death. Also, she did come to work yesterday.

We just called and confirmed with the hospital that they didn't know that Wu Meiqi was Fang Moxuan's mother, and when Wu Meiqi applied for the job, it was obvious that she deliberately concealed this. ”

"Who recruited Wu Meiqi into a psychiatric hospital?" He Jiahui immediately asked.

"Are you worried that there are still Wu Meiqi's accomplices in the mental hospital? You can rest assured that we have checked that there should be no of her accomplices in the mental hospital. ”

Ma Jun went on to say; "The salaries of cleaners in psychiatric hospitals are relatively low, and the turnover of personnel is relatively large, and many cleaners will quit after not working for a long time, so psychiatric hospitals will recruit cleaners all year round.

And to recruit a cleaner, it is basically to fill in a phone number and address, how can you check the family situation. I also asked the mental hospital, and they said that Wu Meiqi usually doesn't talk much about her family situation. ”

At this time, Ma Jun's mobile phone text message rang, he picked up his mobile phone and looked at it, and then said: "The search warrant has come down, we will go to arrest Wu Meiqi now, and then search Wu Meiqi's residence!" ”

……

Wu Meiqi is not at home, and there is no one in her residence.

"I called the psychiatric hospital just now, Wu Meiqi didn't go to work today, she shouldn't have run away after killing someone!" Ma Jun said.

He Jiahui walked to the refrigerator, opened it and looked at it, then looked at the wardrobe again, and said; "The fridge was full and there was a fresh rib. The wardrobe is also full, I didn't bring clothes for the four seasons, and there was a suitcase in the corner, so it shouldn't be a runaway. ”

"Then Wu Meiqi should have something to go out? We stayed and waited for her to come back. Ma Jun said.

He Jiahui opened his mouth and asked: "If you are Wu Meiqi and you have avenged your son, where will you go at this time?" ”

"I see!" Ma Jun nodded suddenly in realization, and then said, "Check immediately, where Fang Moxuan's ashes are placed!" ”

……

In Heung Kong, government-provided columbarium niches are cheap, but there are queues for years to get them.

The cheapest columbarium of a commercial nature is 50,000 yuan, and the feng shui is better, hundreds of thousands to millions of dollars, and if it is placed in a place like a temple, it is even more sky-high.

This is still talking about a square-sized columbarium, not a cemetery, and a thousand-foot mansion with the highest price of a cemetery in Xiangjiang is enjoyed by the rich.

Fong's columbarium is located on the sixth floor of a building, which is a privately owned columbarium.

When the police came here, they saw that Wu Meiqi and her husband were here, they were standing in front of Fang Moxuan's columbarium, their eyes closed, their hands folded, and they were praying silently, as if telling Fang Moxuan that they had avenged him!

Ma Jun stepped forward and said, "Ms. Wu Meiqi, regarding the murder of Yang Lixin, we need to ask you to go back and assist in the investigation. ”

Wu Meiqi opened her eyes and smiled indifferently: "Okay, I'll go with you." ”

Then Wu Meiqi looked at her husband and explained; "I have no regrets about being able to avenge my son, and you have to take care of yourself in the days to come."

"Don't worry, I'll find you the best lawyer! I'm waiting for you to come out! Her husband looked at her affectionately.

Hearing the conversation between the two, Wu Meiqi's husband was obviously also an insider, so Ma Jun continued: "Mr. Fang, you also need to go back to the police station with us to assist the police in the investigation." ”

……

The forensic evidence also completed the search of Wu Meiqi's residence and returned to the police station to report the situation.

"We found a parcel bag at Maggie Wu's house with these things in it." The forensic examiner took out several evidence bags, pointed to the contents and continued:

"It's a capsule box that doesn't have capsules in it, but it does have instructions for use. According to the instructions for use, the appearance and size of this capsule are the same as those of ziprasidone capsules. Whereas, ziprasidone is an antipsychotic drug.

The instructions for use also say that if you take this capsule, you will die of heart paralysis within two to four hours. I judged that the thing that poisoned the deceased was the capsule in this capsule box.

Along with this capsule box, there is also an advertisement for a psychiatric hospital to recruit cleaners, and a Bible, I asked the psychiatric hospital, and they posted the job ad, and I also checked the Bible, which is an ordinary Bible. ”

"Poison and the Bible together? Interesting. He Jiahui said, and the corner of his eye suddenly aimed at another evidence bag, and his heart was shocked.

"What's in this bag?" He Jiahui immediately asked.

"Didn't I just say that the capsule box, the Bible, and the job ad were all in one bag? That's the wrap bag. I also checked, it was a general parcel bag, and there was no clue on it. The forensic officer replied.

However, He Jiahui looked at the bag and fell into deep thought.

On the parcel bag, a pattern is printed: a pair of black angel wings!
