Su Cheng said: "Xu Xuan has an idea that is very interesting, she said that someone may have hired Liu Yan to steal things that Qin's father could not see, and I retorted at the time, if this is the case, why should I go undercover in TTT for so long, the security of Qin's father's house is very poor." After thinking about it, I think it's quite possible, to change it slightly, Liu Yan went to steal the Qin family's things, not Qin's father's things. ”

"Oh? do you mean that Liu Yan started to target Qin Shao, and she didn't find anything in Qin Shao's company, and after entering Qin Shao's villa last night, she touched Qin's father's villa by the way?"

Su Cheng said: "As Liu Yan's undercover TTT, I think Liu Yan has a helper. It is likely that the helpers killed her. Liu Yan went to Qin's father's study, I think it was the helper who suspected that Qin's father's study had something they wanted, or they came here, so they would steal it once. If you speculate like this, the helper or their boss must know Father Qin, and have a good relationship with Father Qin, so they can at least enter the study. ”

"Boss Liu Yan thinks that Father Qin's study is worth investigating. Zoro nodded slowly: "This speculation is more logical. It's possible that Liu Yan got something, right?"

"It's not clear, we don't know what it is. It is possible that the mobile phone took a picture and sent it, deleted it, etc., or it may have been transferred to the helper, and the study window is only three meters from the back wall. Liu Yan was searched and no stolen goods were found. ”

"It may be a helper or a boss who killed Liu Yan to kill her. It may also be the black hand of Old Man Qin, Liu Yan knows too much. ”

"There is this possibility, which is in line with Old Man Qin's mood of passively cooperating with the investigation last night. ”

Zuo Luo said: "We don't care about the motive first, let's find a way to dig out the murderer first." To tell the truth, now there is a case where I first think of the hanged ghost, the hanged ghost commits the crime, one link after another, and it is difficult to follow the vine. It doesn't look like a gang of hanged ghosts at the moment, so it should be no problem to catch a murderer, right?"

This sentence is a question, Zuo Luo knows that if he wants to solve this kind of case, and if he wants to be fast, Su Cheng's play is the key. But looking at Su Cheng's face, he may not have slept for a few hours after working overtime last night.

Su Cheng was not in a hurry: "Let's look at the situation first, it is not possible to assign a surname to the case at present...... By the way, there's a question I've always wanted to ask, but I don't think it's appropriate......"

"If it's not suitable, don't ask. Zoro replied.

"......" Su Cheng was angry: "Lao Tzu just wants to ask." ”

"Why is there so much nonsense? "Grind and chirp.

"......" Su Cheng said to himself in his heart, he is self-educated, a gentleman, and educated, don't worry about him, remember, you can't beat him. Su Cheng took a deep breath and asked, "It's been about eleven months since I arrived in Department Z, and the Falcon team has only been on one field mission, or because the Blue River and Hurricane teams have just returned from the police. ”

Zuo Luo drove silently and said for a long time: "There are three generals under Blue River and Hurricane, who are the leaders of the three teams, commonly known as the small supervisors, although they have different shifts, they have a private relationship with comrades-in-arms. ”

"And then?"

"Normally, it should be...... How to say it. The first reason is that the strength of the two groups of special police in Blue River and Hurricane is slightly stronger than that of the Falcon, and the special police competition, reaction speed, on-the-spot response speed, and skill ability are relatively stronger. The second reason is that more than a year ago, when Liu Mo was still there, Falcon was involved in a scandal. Blue River and the Falcon team work together to take down a 'reading' factory, and the villains are stubborn and armed with guns. ”

Zuo Luo said: "Considering the opponent's firepower and the psychological attitude of the opponent's stubborn resistance, the police adopted a step-by-step tactic to compress their space for survival and resistance. Liu Mo cooperated with Deputy Zhang, who was still in the Anti-Narcotics Department, to handle the case, and commanded the special police to control one area after another step by step. The battle lasted for about half an hour, and the special police used stun grenades and other steps to control the bad guys in two rooms on the second floor in a corner tower in accordance with the order, suppression first, shooting and killing secondary. In the end, the main culprit committed suicide by swallowing a gun, and the others surrendered. ”

"During the operation, the priority of the police was to clean every room, with SWAT teams of two to three people checking all the rooms and looking for drugs and guns. The process lasted about forty minutes, and after the security was declared, the criminal police entered, the physical evidence team collected the evidence, the technical department processed the computer, the forensic doctor collected the body, and a room caught fire, and the fire and ambulance came. The scene was a bit chaotic, and although it was all under control, it was impossible to pay much attention to detail. Zuo Luo said: "Because the criminal police have to cooperate with the Anti-Drug Department to carry out the primary task: to get clues on the spot and hunt down other drug dealers as soon as possible." ”

Zuo Luo said: "Because of the above factors, two days later, Liu Mo called the police, and the Internal Affairs Bureau intervened. The reason is that in the confessions of the bad guys who were caught, they stated that there were ten kilograms of gold bars in the building, worth about two million. This is the hard currency used for trading. However, the Physical Evidence Unit and others said that no gold was found. Due to the suicide of the main culprit, the accomplice was only known to be stored in an area on the second floor, which was being cleaned by the Falcon team at the time. ”

Zuo Luo said: "Because the criminals are in possession of firearms, the special police officers wear germ plate armor body armor, and if one person hides ten kilograms of gold bars, he can hide five packs of cigarettes, and it is possible to take away 20 gold bars of 500 grams." ”

The case was investigated internally for a long time, and the Blue River and Falcon teams, together with some criminal police officers and anti-narcotics officers, were suspended for a month, and even used a polygraph, but the suspect was never found. The Blue River team was involved because one of the criminals said that the things were placed in the second area, and the second area had the Blue River team's SWAT officers, and three other key players said that the gold was placed in the first area. Considering that the criminal's status in the gang is relatively low, the police investigation believes that the probability of the Blue River team committing the crime is very low.

When the investigation was blocked, a member of the Falcon team named Zhao Bao disappeared and the body was later recovered, and surveillance showed that Zhao Bao's car rushed into the sea, eventually causing him to drown. The surveillance captured a photo of the car, and it was Zhao Bao driving alone. Police searched Zhao Bao's home and found a stolen gold bar.

But the subsequent investigation was fruitless, and the police even searched the fixed properties in the names of Zhao Bao's parents and brothers, who were directly related to Zhao Bao, and found nothing. The two special police officers in the same group as Zhao Bao were also investigated in all directions, and nothing was found.

Eventually, the Falcon team was reinstated, and although the Falcon team was the third choice, attendance was still okay. Since then, the Falcon team has been largely absent from the field. At that time, in order to deal with this group of criminals, Falcon and Blue River canceled their shifts and went out with all of them. So afterwards, there was mutual suspicion among the three leaders of the Falcon team, and there were some suspicions among the team members.

Zuo Luo said: "Three days ago, the leader of the falcon team submitted an application for transfer because of a herniated disc in his lumbar spine. In fact, his condition is not serious, and he hopes that by leaving his job, he can make a difference for Falcon. ”

"What does this have to do with falconry?"

"It doesn't matter, maybe he just doesn't want to accept the fact that when he was captain, the Falcon was returned to the SWAT team. Once the Falcon is returned to the SWAT detachment, the establishment will be cancelled and all personnel will be disorganized and assigned to the detachment's operational team. Some of them are likely to be on standby. SWAT recruits a certain number of veterans of the same year every year, and every year is replenished with fresh blood, and most captains are more willing to train and accept new recruits, knowing that even if the Falcon SWAT people join their group, they have a higher degree of identification with the Falcon in their hearts, even if the Falcon no longer exists. Zoro said: "If this is not the case, it is impossible for the doorman special police to mention this matter to you." Falcon is now facing the dilemma of disbanding. ”

Su Cheng said: "Is there no suspicion?"

Zuo Luo said: "The suspicion is never against the suspect, and our requirements for sensitive positions will naturally be higher." ”

Su Cheng nodded slowly and said no more.

……

The emergency department of the First Hospital has temporarily ceased to work, and the temporary emergency department has been transferred to the first floor of the next building. The hospital was very cooperative in this case. Did the doctor use the wrong medicine and cause the patient's death, or did someone drop the medicine and cause the patient's death? It is impossible for the police to explain the details of the case to the public, and at the same time, they will not announce that the drugs have been dropped without clear evidence. Therefore, the hospital very much hopes that the police can investigate clearly and also give the doctors and nurses on duty a clear name.

The nurse's room in the emergency department temporarily became a temporary office for Group 7.

In the first question, Zoro asked, "How much malfeasance is possible for a doctor or nurse?" It is possible that the doctor used the wrong medicine and then changed the label himself.

Zhang Liang replied: "Exclude." "He doesn't explain much, he pushes a piece of material to Zoro.

Zuo Luo didn't read the material, Zhang Liang said to exclude, Thaksin.

The second question, Zoro asked, "When was Liu Yan poisoned?"

Zhang Liang replied: "The time of poisoning is about ten seconds before the convulsions, but when the poison will reach Liu Yan's hands, it is uncertain now." There are many people who have come into contact with Liu Yan. Here is the video of the transcript. ”

Zuo Luo looked at Su Cheng, and Su Cheng said: "Elimination method, first of all, emergency doctors, at least two emergency doctors at night, the first hospital is equipped with three emergency doctors, there is a doctor before Liu Yan, and the patient died in the ambulance." This means that the order in which they visit is uncertain. I read the transcript and there were no doctors scrambling to go out on duty, so I ruled out emergency doctors. ”

"The second group, Liu Yan, entered the emergency room, the female doctor and four nurses, they were likely to give poison to Liu Yan. But the difficulty is high. Five people surrounded this person, receiving electrocardiograms, infusions, and blood drawings, in which the doctor was not involved, and she watched the nurse as she took the first step. At the same time, I looked at the resumes of the nurses, and I didn't find that they had a magic background, so I simulated the movements of the four of them, and I thought it would be very difficult to hand over the medicine to Liu Yan. If there is no contradiction in the low probability, it will be excluded, this is my principle, and the nurse will exclude it all. ”

"In the end, there are four more suspects, the first person, the first female emergency doctor, she can be ruled out for the time being, if she is the murderer, I don't think she needs to say that her first aid methods are correct, after all, it is cyanide, the king of poison. For the time being, I am worried that the murderer is too high-end and wants to get away with it. ”

Su Cheng: "The second person, the inpatient doctor on duty, Liu Yan entered the emergency observation ward on the first floor, she was taken over by the resident doctor, and the resident doctor in charge of the night is usually a newcomer who has just left medical school for a few years, and this one is no exception, twenty-six years old, and the doctor on duty patrols the ward twice at five or six o'clock. ”

"The third person, the nurse on duty in the hospital, there were two people in total, and only one nurse entered the ward twice, the first time was when he entered the room to check the drip and record it. The second time was at nearly six o'clock, when she entered the ward to change the drip. ”

Su Cheng: "The fourth person, the uniformed policewoman in the ward, she is Zhang Liang's direct internal subordinate, and my suspicion is close to the female doctor, so she can be ignored for the time being." According to my train of thought, now only the inpatient nurse and the inpatient doctor on duty remain. ”

Su Cheng: "The most critical point is the time of committing the crime, that is, the time to give poison to Liu Yan. Let's analyze it, the nurse entered the ward twice, the first time she entered was to check the drip, Liu Yan's needle had been punctured in the emergency room, and all she had to do was to check and record. At the same time, sign the list, what time do you start to hang any medicine, and the list is placed at the head of the bed. It is difficult for her to directly touch Liu Yan's hands, and she can touch her feet when placing orders, but because Liu Yan's left hand handcuffs are buckled together with the bed frame, it is impossible to make much movement, so the poison is placed at her feet, and Liu Yan can't get it. ”

The nurse entered for the second time and changed the drip, according to the record, it was 5:47, this time she not only changed the drip and signed, but also checked Liu Yan's left hand to see the needle. In the transcript, the policewoman was on the right side at the time, this was an opportunity to give poison, and she only had this chance, but it was still that reason, her left hand was tortured, Liu Yan wanted to secretly take poison, and her right hand was going to take the medicine from her left hand, and she took the medicine while the policewoman was not paying attention, and took the medicine ......"

Zhang Liang: "Wait, why did Liu Yan take medicine?" Zhang Liang wondered after listening to it, Su Cheng's logic was that Liu Yan begged for death.

"I don't think Liu Yan thinks it's poison......" Su Cheng glanced at Zuo Luo, they suspected that the Horse Bureau had been making a criminal plan, if Liu Yan's plan was so good, then there was a chance that it had something to do with the Horse Bureau. But theoretically, this time it really doesn't look like the hanged man's style. Su Cheng explained: "Liu Yan deliberately vomited and went to the hospital, she wanted to make herself sick according to a plan, but she never thought that her boss was vicious...... We will not discuss these for the time being, but focus on the facts of the case itself. ”

Zoro said: "The doctor on duty in the hospital." ”

"The inpatient doctor on duty entered a total of twice, the first time was at five o'clock with Team Zhang, Liu Yangang entered the ward, entered the examination, and signed with the female doctor to take over the patient. At this time, he had a preliminary examination of Liu Yan, and it was very likely that he would give poison to Liu Yan. Su Cheng said: "The second time, at six o'clock, the doctor made another round." This time, he still checked Liu Yan, in addition to looking at electrocardiogram and other instruments, he also looked at the pupils and touched the palms of his hands. It is also very likely that the poison will be handed over to Liu Yan. ”

Zhang Liang said: "That means ......"

Zoro said: "You'd better listen to him, he often underbeats." ”
