The trace examiner put on gloves and first made an overall observation of the scene, then took photos to record the scene and opened the passage as soon as possible.

Xie Qing asked Li Ji: "Are you sure the victim is dead?"

Li Ji said: "Yes, the small muscle groups are stiff, it's been almost three hours. It's a mess inside, there is vomit, guess it's poisoning."

Xie Qing asked again: "Did you move the body?"

Li Ji deliberately widened his eyes, "You look down on me, don't you? I just checked to see if the person is dead."

Xie Qing smiled slightly, "Routine."

Li Ke said: "Is this your grandfather's ward?"

"How is that possible?" Li Ji rolled his eyes at her, "My grandpa's ward is in room 506."

Li Ke said, "It's far away. How did you find it?"

Li Ji raised his chin towards the bathroom sign, "My grandpa likes to be clean. Although he is paralyzed, he doesn't want to defecate and urinate in bed. I helped him over here..."

When he helped the old man over, he didn't find anything unusual. After sending the old man back to the ward, he went to the toilet again.

He had been irritated and constipated these days. After serving the old man, he wanted to squat in the toilet quietly for a while.

About three or five minutes later, he heard a slight door ring in the corridor, but he didn't pay attention to it. He squatted for nearly a quarter of an hour, solved the problem, and then washed his hands and left.

When passing by 524, he found that the door was open a foot.

He subconsciously looked inside and found that there seemed to be a person lying on the ground. He hurried in to check, but found that the person had begun to stiffen.

Li Ke asked, "Is the light on in the room?"

Li Ji pointed to the light in the corridor - the body was on a bed, close to the door, and the light shone in, almost reaching the waist of the body. The

trace examiners acted quickly. Deng Wenxiang came out and said to Xie Qing, "The forensic doctor can come in."

Xie Qing thanked her for her hard work and walked in with the investigation box.

She also looked at the door. There were two beds in the room, one of which was empty, and there were a lot of nutritional supplements piled on it, such as fruits, canned milk powder, etc.

The patient on the bed outside should be the deceased - the deceased was wearing a blue and white hospital gown.

The floor was paved with tiles, and the conditions were poor, so no footprints could be found.

The quilt on the bed was in a mess, with most of it hanging on the ground. Four small medicine bottles, half an apple, a pear, and some melon seeds and peanuts were scattered under the bed.

The deceased was a male, about 40 or 50 years old, of medium build, and obese. He was lying on the ground with his head and feet swaying, his face up, and white foam around his mouth. There was vomit on the bed and the floor, and the air was filled with the sour smell of gastric juice.

The medical records were open. The patient had diabetes and was undergoing a glucose metabolism test.

After reading the medical records, Xie Qing put down the investigation box, first measured the rectal temperature, then took photos, and finally performed a superficial examination of the body.

The deceased showed obvious signs of suffocation, with white foam and relatively fresh blood around his mouth - probably caused by biting his tongue, as there were no old bite marks on his tongue.

His lips and nails were cyanotic, and there were bleeding on his eyelids and conjunctiva.

When the hospital gown was opened, obvious body spots were visible, and rigor mortis had developed to the major joints.

There were no obvious contusions on the surface of the body for the time being.

She stood up and said, "Comprehensively, the deceased died of rat poison. All the food, vomit, and excrement here must be sampled for testing."

"Are you sure?" Tan Yi's voice came from outside the door.

"Let me take another look." Cao Haisheng walked in quickly.

"Master, Captain Tan." Xie Qing handed the field to Cao Haisheng and retreated outside the door.

Tan Yi nodded at her.

Xie Qing said, "The deceased died rapidly, with obvious rigor mortis and body spots. Combined with the body temperature, the time of death should be around two in the morning. The specific conclusion can only be drawn after autopsy and testing."

Cao Haisheng stood up, holding his waist. "The characteristics are obvious. I agree with Xiao Xie's opinion."

"Old Hou!" A woman screamed miserably in the corridor.

"Dad!"

"Dad!"

"Family members of the patient, please do not make loud noises in the inpatient department."

"Other patients are still resting, please understand."

"My dad died in your hospital, and we haven't settled accounts with you yet, so why bother with understanding!"

"Yes, call your leaders!"

"The police are investigating the scene, and outsiders are not allowed to approach."

"Police, what does it have to do with the police?"

"My dad was killed in the hospital?"

"Old Hou, you died tragically..."

...

More than a dozen family members of the deceased came, and the corridor was in chaos.

Du Zhun, Liu Feng, Li Ji, and Li Ke, with two security guards, stood in front and could not hold on any longer.

Tan Yi walked over and showed his work ID. "I am the captain of the Second Brigade of the Criminal Investigation Brigade of the Municipal Bureau. If you have anything to say, tell me. Arguing won't solve the problem."

He was wearing a leather jacket and glasses, and although he looked more gentle, he was tall and impressive, and his position was intimidating.

The scene was quiet for a while.

A plump, middle-aged woman with an afro wiped her tears and asked in a sharp voice, "Tell me, how did my old Hou die?"

Tan Yi said, "We can't draw a conclusion yet. We will inform you of the specific situation after the autopsy."

A young man in his early twenties asked, "Is it really my dad? Could they be mistaken?"

Tan Yi said, "It can't be mistaken, the nurse has verified it."

The middle-aged woman wiped her tears with her sleeve, "My old Hou was just a contractor, but he ended up like this. Who did he offend?"

Tan Yi said, "This is what I want to ask you too. Mrs. Hou, please think about it carefully. Does the victim have any enemies? Has he offended anyone recently?"

The family members looked at each other.

The detectives seized the opportunity to communicate with the family and inquired about the details before Hou Zi'an's accident.

Fu Da squeezed through the crowd, walked in front of Tan Yi, and whispered: "The nurse on duty fell asleep and did not find the abnormality of 524. I asked the communication room downstairs and no suspicious people were seen entering or leaving."

Xie Qing took the samples that needed to be tested and put them in the investigation box. She said to Cao Haisheng, "Master, I will go and inform the family."

Cao Haisheng nodded.

Hou Zian was killed by him, and the police have the right to perform an autopsy on the body.

Xie Qing found Mrs. Hou and said, "Please accept my condolences. We are now taking your husband's body to the funeral home for an autopsy."

Mrs. Hou was a little confused, "Are you a forensic doctor? How did he die? Can we not perform an autopsy?"

Xie Qing said, "I am a forensic doctor, but I can't answer this question for the time being. I can only tell you the truth after the autopsy is completed. Please understand." She bowed slightly, turned around and walked back.

Tan Yi winked at Fu Da.

Fu Da organized people to take the family of the deceased to the nurse's station to prevent relatives from rushing into the body and contaminating the evidence.

...

Funeral home, autopsy room.

The master and his apprentice worked together to move the corpse to the autopsy table.

The victim was heavy, and Cao Haisheng held his waist unbearably.

Without waiting for his instructions, Xie Qing took the initiative to ask for help: "Master, this is not a difficult job, you record, I will do the operation."

Cao Haisheng looked guilty, "Thank you for your hard work, Master will treat you to breakfast later."

"Okay." Xie Qing picked up the scissors, "I heard that a wonton restaurant opened near our bureau, and the sour soup wontons are quite good."

Cao Haisheng smiled and said, "Okay, let's eat that."

Xie Qing used scissors to cut open the victim's clothes and pants, and evacuated from the body in an orderly manner.

Although she had checked it before, she still checked it again and still found nothing abnormal.

Next, Xie Qing shaved the dead man's hair.

Although Hou Zi'an was fat, he had good facial features, a square face, thick eyebrows and big eyes, and looked very much like the upright and handsome old men in various movies and TV dramas.

According to the anatomical procedure, Xie Qing first opened the chest and abdomen, and most of the organs showed congestion and edema.

The stomach was full of water, but no food. The time of death was basically consistent with Xie Qing's judgment.

Xie Qing took some gastric juice and blood.

Then opened the cranial cavity.

Xie Qing found a saw and said to the corpse, "I'm sorry."

The master and apprentice put on masks together - bone foam would fly with the movement of the saw, and whether it was sucked into the mouth or nose, it would be a huge test for humans.

Cao Haisheng said, "I'm strong, let me do it."

Xie Qing started sawing, "Don't worry, I've practiced before."

The naked corpse and the beautiful girl with the saw.

Cao Haisheng shook his head and looked away, unable to bear to look any longer - he didn't feel sorry for the deceased, but for Xie Qing.

He said, "Your family conditions are good, why don't you change jobs."

Xie Qing understood his thoughts, "Master, although it's a bit cruel, I think it's very meaningful."

"Okay." Cao Haisheng turned his head, with a little more admiration in his eyes, "Master supports you."

Soon, the skull was opened - the brain was swollen, and there was a little scalp-like hemorrhage in the subarachnoid space of the brain.

Cao Haisheng said, "It is basically confirmed that it is rat poison."

Xie Qing took out the needle and thread and sewed quickly, "Yes, it should have been put in the cup. Combined with what Li Ji mentioned, the murderer came back and probably wanted to erase the fingerprints on Hou Zi'an's cup."

Cao Haisheng wrote the last sentence on the autopsy form, "What did Li Ji find?" He came late and didn't have time to understand the details.

Xie Qing told him while sewing.

Cao Haisheng said, "Maybe he will also become the subject of investigation."

...

Li Ji really became the subject of investigation.

He sat in the interrogation room with a long face, complaining: "I don't even know the deceased, how can I become a suspect?"

Li Ke deliberately teased him, "That's hard to say, you have very strong anti-detection capabilities, and occasionally you play a killer..."

"Cough!" Tan Yi came in, coughed, and gave Li Ke a warning look.

Li Ke stuck out his tongue.

"You deserve it!" Li Ji was relieved, "I

told you not to talk nonsense." Tan Yi sat down, "The patient in bed three of 506 testified that you went out once around early morning."

Li Ji said aggrievedly, "Captain Tan, I went to the water room to get hot water. The hospital has just started heating and it's not hot enough. I went to change the water in my grandfather's hot water bag. The old man remembered that I went out, so how could he not remember that I got hot water?"

Tan Yi said, "How long have you been gone, and who did you meet on the way, think about it carefully."

Li Ji knew that the murderer might have appeared on the fifth floor at that time, so what he saw and heard was extremely important.

He said, "Most of the patients and their family members were asleep, and even the nurses at the nursing station rarely showed up. I didn't meet anyone on the way, except for a few people in the bathroom on the fourth floor. They might all be bedside attendants, but I didn't know any of them."

Tan Yi stood up and said, "Cooperate with the portrait artist later and describe the people in the bathroom."

Li Ji said, "Captain Tan, has it been proven that it was rat poison?"

Tan Yi said without turning his head, "The autopsy results are out. The deceased didn't eat anything, but he must have drunk water."

Li Ji said seriously, "I understand!"
