Xun Mu nodded approvingly and asked, "Then what?" ”

"If not, you have to consider that the suspect is still in a comatose period, so there will be fewer clues, and you can only consider it from the 'motive'." Qi Yuan continued:

"The motive has just been made very clear by the Su team, which can be divided into two aspects - or, there is a personal conflict with the victim's family; Or, there is a grudge with this hospital.

It is still necessary to start with the list itself, and conduct interviews and investigations with them and their relatives and friends, focusing on two aspects, one is the relationship with the victim's family; The other is to check whether there has been a doctor-patient dispute.

If the possibility of other patients and their families being excluded from committing the crime, and the scope of suspects falls on medical staff, then the focus is on whether they have been treated unfairly, including rating assessment and even unspoken rules.

However, I think the possibility of the doctor is relatively low, and a group of people entered at the same time during the ward rounds, so it stands to reason that there are no conditions for committing a crime, even if the crime is committed, the speed of poison will not be so fast. In contrast, nurses who enter the ward from time to time and enter the ward alone are more suspicious.

Of course, if there are doctors and interns who have gone in alone in advance, then the suspicion is great.

The above is what I think is the entry point for the investigation of the case, Xun team, Su team, Song brother, what do you think? ”

"Hmm." Brother Song bowed his head slightly: "It's basically more comprehensive, I don't have anything to add." ”

"First of all, that colleague should be asking." Su Ping said: "When he comes out, you can ask him if he has any gains, and he is also an old criminal policeman, so it is impossible not to consider this problem."

But if he really doesn't realize it, then let's ask it again, and it's not in the way.

Of course, the victim's subjective judgment is actually inaccurate, so we can directly proceed to the second step. The victim's family will be handed over to me and Lao Xun to deal with, Song, you can take someone to ask the medical staff and interns first. ”

"Okay." Brother Song's jaw was about to extinguish the cigarette butt that had only been half smoked.

Su Ping waved his hand: "It's not bad for these two minutes, I'll go again after pumping." ”

"Hmm."

……

Three minutes later, Brother Song took out the walkie-talkie, arranged the task, and then led Qi Yuan to the doctor's office and found the head of the medical team in charge of the victim's family, Deputy Director Liao Guofeng.

"Director Liao, hello, I'm a criminal policeman of the Criminal Investigation Detachment, Zhao Qingsong," Brother Song asked, "Regarding this poisoning case, I want to ask you about the situation, I don't know if it's inconvenient?" ”

"You suspect someone poisoned the hospital, right?" Liao Guofeng chuckled, nodded, and said, "Come to my duty room, let's talk alone." ”

"That couldn't be better."

The three of them walked to Liao Guofeng's duty lounge, and he poured a glass of water for Qi Yuan and Brother Song.

Then he took the initiative to say: "I arrived at the hospital at about 7:10 this morning, had breakfast in the cafeteria, went to the office at 40, and after the shift was completed at 8 o'clock, I led my colleagues and interns in our group to start ward rounds."

About half-past eight, I found the ward—they were the fourth group, and each group took about five minutes.

In an internal medicine ward like ours, there is not much ward rounds, but nothing more than asking the patient how he is doing and whether he feels unwell, so as to decide whether the medication and dosage need to be adjusted today, whether he needs to arrange another examination, etc., and if the symptoms are more serious, the signs will be measured.

It's not like the surgical ward, most of them have wounds after surgery, and they have to change the dressing every day, but as far as I know, they should also arrange for interns to go after the ward rounds.

Sorry, I'm too far away, let's come back. When I found out about their ward, I found that the patient's symptoms were very strange, and he was trembling all over, so I picked up the brief report of their bed and looked at it.

At the same time, when my colleagues went to the nurse's station to get blood drawing tools, I carefully observed the signs of the four poisoned patients, and found that the youngest child had lost his vital signs.

At that time, the big guys were a little panicked, and I was actually a little bit of a master, but fortunately I was still stable, and quickly notified the police comrades who were responsible for investigating their poisoning case, and then urged my colleagues to hurry up, quickly draw blood and go to the emergency green channel, to see what kind of poisoning they were, so as to deal with it as soon as possible.

The test results came out quickly, and it turned out that it was a poisonous rat poisoning. When I learned about this, I was surprised, and I quickly called the attending doctor who was in charge of the admission record yesterday and asked him what was going on, why was the serious symptom of strong rat poisoning, and why was it not written in the major medical records and admission reports.

The colleague was also very aggrieved, brought the medical record book from the nurse's station, and also called up the electronic medical record from the system, both medical records had quite detailed blood test reports, and there was no mention of strong poisoning of rats.

I called the laboratory department again and inquired several times, and made sure that when they were admitted to the hospital, there was no strong rat poison in the blood, and I was sure that this was not a medical accident, but someone deliberately poisoned and murdered the patient after receiving treatment, so I told the police comrades in the brigade about it.

Immediately after that, it was for the three patients to administer first aid. Those who have died, we also regret it, of course the murderer must be brought to justice, but for us doctors, the living are more important, and it is impossible to say that in order to cooperate with you to solve the case, the best rescue time is wasted.

So at that time, I was anxious about the people in our group, and rescued the three patients as soon as possible, mainly infusion, regulating body fluid balance, diuretic hormone, promoting poison discharge and symptomatic treatment.

At the same time, they also used a painless gastroscope, but their stomachs were empty, and they had washed their stomachs when they were admitted to the hospital, and it was probably not oral poisoning, and in my experience, the way to ingest poison could only be to enter his body with a drip. ”

Brother Song chose the key point to record the information he said, and then asked, "Director Liao, do you have any suspicions?" ”

"Me?" Liao Guofeng pointed at himself, shook his head and smiled: "What do I suspect, please, I'm just a doctor, at best, I can only cooperate with your investigation, who can I suspect?" ”

Brother Song also chuckled and followed: "To be honest, through monitoring and preliminary understanding of this case, we believe that the suspect is nothing more than the patients and their families in the same ward, as well as you medical staff who have entered the ward." ”

Liao Guofeng nodded: "Understood." ”

"Patients and their families also said, can you give us a general introduction to the medical staff?"
