Work is busy, but you still have to eat.

The master and the apprentice sent the samples back to the technical room, changed clothes and went to the wonton restaurant, each ordering a bowl of sour soup wontons.

After being busy for half a night, they were sleepy and tired. Eating a bowl of hot and sour wontons was simply a pleasure.

Cao Haisheng smiled and said, "I have been in the police station for so many years, but I didn't know there was such a place nearby. You little girl found out after just one month. It's not easy."

Xie Qing said, "Li Ke and I both love to eat. After work, we have nothing to do, so we like to wander around the city. Wherever there is delicious food, we want to go and have a bite."

Cao Haisheng shook his head and said nothing. Even

if he didn't say it, Xie Qing understood.

Most of the fathers have such a consumption concept, and the family conditions do not allow them to spend lavishly.

Cao Haisheng has the clarity of a middle-aged man. He is not sharp, does not show off, is not greasy, and does not preach. He is very comfortable to get along with.

Xie Qing is very fortunate to have met such an elder who is both a teacher and a friend after traveling through time.

Back in the office, the technical room's test results on vomit, blood, and gastric juice came out.

At 7:30, the second brigade called, and the master and apprentice went downstairs for a meeting.

Conference room.

The relevant information of the Hou Zian case is already on the blackboard. It is not Tan Yi's handwriting, but Li Ke's.

Xie Qing read it through and immediately felt the difficulty of this case.

First of all, the government's control over rat poison is not strong, and the source is difficult to investigate.

Secondly, the deceased is a nouveau riche with many relatives and complicated family relationships.

Secondly, there are many seemingly real enemies, including competitors, workers who owe wages, and owners who have had armed fights over construction quality issues.

Finally, there are possible psychopaths in the hospital.

Tan Yi is a man of few words, and he asked Fu Da to summarize the case right away.

Hou Zian is 52 years old and was hospitalized for diabetes ten days ago. His condition is not serious and he can take care of himself, so his family members did not accompany him around the clock. They were only responsible for delivering two meals a day and that was it.

In the twelve hours before the incident, only his wife Zhang Xiuyu and eldest son Hou Donglai delivered meals once each.

Hou Donglai delivered lunch and left after delivering it.

Zhang Xiuyu came at 5:30 in the evening and left at 8 pm - it was usually like this.

According to the nurse on duty, after eight o'clock, most patients rested, but Hou Zian had diabetes and needed more activities, so he usually walked up and down and back and forth several times.

This situation is quite common, so no one cares where he went and what he did. Occasionally,

one or two familiar people would come to Hou Zian to chat, but this situation is rare.

In public hospitals, there are many patients and most nurses are very busy. It is difficult to pay special attention to a patient. Apart from the condition, they don't know much about Hou Zian's personal situation.

In addition, if someone takes the stairs on the other side, they will pay even less attention.

The patient on the fourth floor said that at about one o'clock in the morning, there was a sound of heavy objects and small items falling to the ground on the floor, but because there were many seriously ill patients in the hospital and there were nurses on the fifth floor, the people who heard the sound ignored it. After

Fu Da introduced the situation, Deng Wenxiang from the Trace Examination Department spoke.

He said that the scene was in chaos and there was very little valid evidence. Only the fingerprints wiped off the cup could prove that the victim did not commit suicide. The fingerprints in other places were messy, and the comparison work would be carried out after the meeting. There was not much that could be expanded on the forensic part. The cause of death of the victim was clear, and the test results were on the blackboard - there were no toxic ingredients in the hot water kettle, no food, and high concentrations of poisons in the vomit, blood, gastric juice, and cup. Cao Haisheng asked Xie Qing to speak, and Xie Qing gave a relatively detailed explanation of the part about rat poison. She said: "Rat poison is highly toxic, white and odorless, stable in nature, and quickly absorbed by the stomach, with symptoms appearing immediately. Most incubation periods are 10 to 30 minutes, and death usually occurs within half an hour to three hours after poisoning." "After the poison takes effect, the victim may also have symptoms such as confusion and light coma at first, but this process does not last long. Then, tonic and paroxysmal convulsions begin, like epileptic seizures. Therefore, the people downstairs heard the noise, which was probably shortly before the victim's death." "After testing, the concentration of toxicity in gastric juice is extremely high. Combined with the situation of gastric emptying and the testimony of the patient downstairs, it can be determined that the deceased drank water at least after 11pm." "There were not many people walking around the hospital at this time, so the possibility of finding the victim poisoned was small. Therefore, I think the murderer had control over the time and the environment of the hospital, and the poison in the cup would not have been put in advance." Fu Da said, "Xiao Xie, what you mean is that the murderer came in at around 11pm at the earliest?" Xie Qing nodded, "Unless someone can prove that Hou Zian did not drink water before 11pm. Moreover, Hou Zian has money and a mobile phone with him, Living alone in a ward, it must be locked at night. The murderer had a very good grasp of the timing of poisoning. He must have observed the victim for a long time. " Fu Da nodded, "It makes sense. If the murderer was not familiar with the deceased, he took advantage of the deceased's absence to poison him. If he was familiar with him, he might have been in the ward until the fingerprints were processed. " Tan Yi said: "He may not have been in the ward all the time. The murderer is not a killer. He does not have such a good psychological quality. He took advantage of the deceased to poison him. The victim went to the bathroom and sneaked into the room to poison him. Fu Da disagreed, "Just like what Xiao Xie said, the murderer investigated the victim in advance, which shows that he had planned it. He could have easily wiped it out, so why would he risk coming back?" Tan Yi said, "What you said makes sense, but I stick to my opinion. The victim died at 2 o'clock, but the murderer left at 4 o'clock. This time is when the elderly get up at night. Since he If you had done the investigation beforehand, you shouldn't be so stupid." Fu Da continued to counterattack Tan Yi with the previous question, "Then why didn't he wipe his fingerprints before leaving?" Tan Yi said: "This shows that the murderer has a bad psychological quality. Premeditation and action are sometimes two different things. When poisoning, on the one hand, he was worried that the victim would suddenly come back, and on the other hand, he was worried about being seen by others. After he left the room, he repeatedly reviewed the process of the crime and found that he had left fingerprints, so he risked going back. " "Well, this statement is more convincing." "Yes, yes, if I were the murderer, it would be inevitable." "Could it be a woman?" "Why, I'm a woman too?" "That's true." "Get lost, my wife is not like that."

"Hahahaha..."

Du Zhun is an expert at livening up the atmosphere. The criminal police who had been busy for half the night finally cheered up with laughter.

Fu Da lit a cigarette, "Captain Tan's argument makes sense, but mine is not without reason either. We'll see after the case is closed. If you lose, I'll treat you."

Everyone was happy.

"Okay, then we'll wait."

"I want to eat hot pot."

"I don't have such high requirements. Lamb and scorpion will do."

...

"Okay." Tan Yi stood up, "The security of the inpatient department is non-existent. It is not difficult to enter and exit the hospital at night. Based on the clues we have, we are not yet able to determine the scope of the murderer, but I personally think that the focus of the investigation should be inside the hospital. Let's concentrate on checking the people in the hospital and the relatives of the deceased first."

"Okay." Fu Da understood the spirit and led a group of people out.

Xie Qing and Cao Haisheng also went upstairs.

After returning from the bathroom, Xie Qing received a call from Xie Xun.

"Dad, something happened."

"Something happened."

"Go ahead."

"I heard about you and your sister. Your sister said that she wants to apologize to you in person... If you have any other ideas, you can tell me."

"Dad, there is no need to apologize. It's meaningless. I don't want it."

Xie Xun fell silent.

Xie Qing knew that he was a businessman and could understand the weight of her words better than she did - the original owner did not grow up at home, Chen Yuehua was partial to her, and the gap between the sisters was not a day or two. An apology would only make them more distant, not closer.

However, for a father, it is undoubtedly extremely painful to see his own children not getting along.

After a long time, Xie Xun said, "Forget it, do you have any requests?"

Xie Qing didn't have any at first, but suddenly an idea came to her mind, so she said, "Dad, I want to use the money my grandpa left me to buy a small villa with a basement. If you buy a house, please help me look for one and find a reliable decoration team. What do you think?"

Xie Xun asked, "The villa is not safe, right?"

Xie Qing said, "Dad, I'm a forensic doctor and I don't have much money."

"That's true, hehe..." Xie Xun laughed softly, "Okay, Dad understands what you mean. Relatives from afar are more friendly, so this is also good."

Xie Qing said, "Thank you, Dad."

At this time, it was difficult for children to move out before getting married - living in a dormitory was another matter.

Xie Qing achieved her goal through this matter, which was also a side benefit.

By then, she would have her own house, and in her spare time she would do carpentry work, cook delicious food, and take care of flowers and plants. It was simply too beautiful.

In the afternoon, Xie Qing followed Cao Haisheng to do two appraisals and did not return until the evening.

While eating in the cafeteria, she met Li Ke who had been busy all day.

The little girl gulped down a large bowl of egg soup and wiped her mouth, "Comfortable!"

Xie Qing said, "How is it, is there any progress in the case?"

Li Ke picked up a tomato box and said, "I'm in charge of the hospital. So far, no one who knows Hou Zi'an has been found from the first floor to the seventh floor. The cleaner said that Hou Zi'an was occasionally not in the ward in the afternoon and was out for quite a while. His whereabouts have not been found yet."

Xie Qing nodded.

Li Ke said again: "I think this is a clue, what do you think, Qingqing?"

Xie Qing said: "I think so too, you can start from the woman's side and see if he has a mistress?"

Li Ke blinked his eyes: "Mistress?"

Xie Qing searched the words in her mind, "It means a second wife."

"Oh... yes!" Li Ke slammed the table, "You are really amazing, why didn't I think of it."

Xie Qing said: "Men become bad when they have money, isn't this normal?"

"This..." Li Ke poked Mi Fan, "How can it be so weird? Isn't your father a good person?"

Xie Qing said, "My grandfather is a professor. He is old-fashioned and strict. My grandmother is even more so. My father has been influenced by him since he was a child. He is quite decent in this regard." In the book, Xie Xun has always been quite upright and has never made mistakes in matters of men and women.

Li Ke was very interested, "Do you think our Captain Tan's family is rich or not?"

Xie Qing was about to speak when a large figure suddenly passed by. She looked up and saw Tan Yi looking at her and Li Ke inquiringly.

She said, "You think too much. As a public official, it is impossible for him to have a mistress regardless of whether he is rich or not."

This is a standard answer.

Tan Yi nodded with satisfaction and left with a large handmade leather bag on his back.
