He heard Ding Chunshan’s meaning, He Hanzhu called himself over, which seemed to be related to the case of the death of the Fu family.

Su Xuezhi went to talk to the principal, and obtained permission, and then got on Ding Chunshan's car and hurried to the headquarters.

She was taken in by her secretary and saw that there was another person in the office besides He Hanzhu.

She was a woman in her fifties, wrapped in a gorgeous marten fur, wearing a ring with huge gems inlaid with her hands, but her face was haggard and her eyes were swollen. She sat in a chair, her eyes full of despair and anger.

Su Xuezhi recognized her. At Wang Xiaokun’s birthday party that night, he met her wife, the mother of the big house in Fu Mingcheng.

Su Xuezhi remembered that night, she looked like she was only in her forties at most. However, in just over a week, she suddenly became like this, with the gray hair on her head, which made her look extremely old.

Su Xuezhi paused, walked in, greeted He Hanzhu, who was sitting behind the desk, and called out to the commander.

If there are outsiders, it is naturally inconvenient to call them cousin.

He Hanzhu pointed to the woman who was sitting aside and staring at her: "This is Mrs. Fu, I believe you have seen it too."

Su Xuezhi turned to Mrs. Fu. Before she could greet her, she suddenly stood up from the chair and walked towards her quickly. She grabbed her hands with her hands and looked at her with her eyes curled up.

"You are the Xiao Su who has been in the newspaper before? Help me quickly! As long as you avenge me, I can satisfy you whatever you want!"

The strength of her hands was extremely strong, and her skin was cold. Su Xue's hands were sore that she couldn't break free.

He Hanzhu got up and walked over.

"Mrs. Fu, don't be excited, have something to sit down and say."

Su Xuezhi took the opportunity to pull out his hand, put it behind his back, and rubbed it quietly twice.

He Hanzhu glanced at her hand that was huddling behind her back and moving quietly.

"That's right. Although there is a medical examination report, Mrs. Fu still insists on confirming..."

Mrs. Fu couldn't wait to interrupt him.

"Xiao Su, my son has quit drinking! It's true! He will never drink so much! You believe me! When I saw it, I was stunned! What should I do in the future! A bad person must die well! At around 3 o'clock that afternoon, my son had just accompanied his father to the study and was busy dealing with business matters! My daughter-in-law and several servants in the family could testify... How could he be so drunk that he fell into the water by himself... He didn't drink alcohol in the study! The bottle of wine was framed by the murderer! The shameless vixen, who was rushing to be a concubine, was pretending to be anything good to give birth to..."

Mrs. Fu probably was too excited and spoke incoherently.

"The eldest son was found at around 5:00 pm. He was in a pool next to the dog room of the Fu family's back garden. He raised a few hunting dogs and often went there. We found two bottles of hidden spirits and empty bottles in his study. Based on the medical test report, it was speculated that he was drinking in the study room, and then went to the dog room and fell into the water and had an accident."

He Hanzhu inserted it in time and explained to Su Xuezhi.

"Commander! Impossible! His father is like this, where did he feel like he's going to drink and get a dog? It's the guy from the second room that's what he did! He put the wine in! I will never let it go!"

Mrs. Fu gritted her teeth, rushed towards him again, and pulled his arm desperately.

"I understand!"

He Hanzhu hurriedly broke free, coaxed him, and brought the person back into the chair, then turned to Su Xuezhi.

"Mrs. Fu did not accept the first autopsy result, but Ryan insisted that there was no need to re-examination. She knew that you had helped solve the case several times before, so please go and check it out again by name."

Mrs. Fu's red and swollen eyes kept crying: "Xiao Su, you must find out the truth for my son! He was killed by someone! My feelings will never be wrong!"

Su Xuezhi looked at He Hanzhu.

Since he called himself over, he must have agreed to Mrs. Fu for a second autopsy.

Sure enough, he said, "I'm sorry, go check it again to see if there is a new situation."

Su Xuezhi nodded: "No problem, I will try my best."

After Fu Jiansheng was found drowned in the water, he was already exhausted, but the Fu family did not give up and sent him to Qinghe Hospital for emergency treatment. Now the body is in the morgue of the hospital.

The location where Ryan performed the autopsy yesterday was also here.

Su Xuezhi brought the tools to Qinghe Hospital. When she was about to enter, she met Mr. Ryan who rushed over after hearing the news.

He was a little dissatisfied with the command's arrangement for someone to re-examination again, thinking that it was distrust of himself. When he learned that the young man in front of him who had no beard and looked at the thin skin was just an undergraduate student in a military medical school. He could no longer bear it and said in a stiff tone: "Commander He, I put down my work for your sake and came here from the capital to assist in the investigation of death. Your professionalism is an insult to my professionalism!"

He Hanzhu looked at the son of the Su family standing beside him, and smiled and comforted: "I can assure you that I absolutely respect and trust you and your authority in this regard, otherwise I would not have thought of asking you to come here to help me. This time it was really special. The mother of the deceased had only this son, and she could not accept the result and was extremely sad. You also know that people will inevitably lose their minds in this situation. She insisted on calling the name and asking this young man to come and check it again. There is really no reason for me not to satisfy the last wish of a poor mother, so I have today's arrangements. I believe that with your demeanor, you should be able to understand."

Ryan's mood calmed down a little. He looked at her and said, "Young man, the mother of the deceased insisted that his son did not drink alcohol during his lifetime. It was just a self-hypnosis of a poor woman! In my nearly thirty years of work experience in assisting Scotland Yard to solve the case, I have encountered a murderer who killed people by injecting poisons. Injecting alcohol is naturally a way of committing crimes. But I have checked that there are no pinholes on the deceased's body, which can rule out the possibility of injecting alcohol to fake drunkenness!"

Su Xuezhi thanked him for his understanding. After dressing, she took the assistant provided by the hospital and entered the morgue.

He Hanzhu seemed not very willing, but in the end, he took the mask from a doctor in the hospital, put it on, and asked Ryan before following him, "Do you need to go in and check it out?"

The other party nodded: "I think I can go and see what this young man can do. I hope God blesses him to not cut his fingers wrong when he takes the knife." As he said that, he followed in with several doctors from Qinghe Hospital.

The deceased had his clothes removed, his bald head and his hair were probably shaved off during the last autopsy and lay flat on a cement platform. He was visually measured to be around 1.78 meters tall and weighed about 160 kilograms. He belonged to the strong type of adult men.

On the way to the hospital, she had already seen various records related to the case provided by He Hanzhu.

The deceased died two days ago on the afternoon.

According to the testimony of the Fu family, the exact time is between 5:00 and 6:00 in the afternoon.

At around five o'clock, a servant from the Fu family saw him coming out of the study from afar.

At six o'clock, the servant who was responsible for feeding the hunting dog regularly entered the dog's room and found the body.

In other words, the maximum soaking in water will not exceed an hour. In addition, it is winter and the temperature is very low. Now the appearance of the corpse is not much different except for the corpse spots.

Mr. Ryan's first autopsy yesterday was mainly aimed at verifying whether the deceased had drunk alcohol before his death, whether he died before falling into the water, or drowned in the water.

He gave his judgment: after drinking, drunk, died after falling into the water.

Now, because of Mrs. Fu's insistence, the main purpose of Su Xuezhi's second inspection is similar to the first time, and it is also to verify the alcohol intake status of the deceased before his death.

As the British said, there are only two possible ways to detect high concentrations of ethanol in the blood.

The first type is self-intake.

The second type is to enter blood circulation through intravenous injection.

She first checked the possible injection location, her head, elbow in the middle, wrist, back of her hands, back of her feet, ankles, and finally even the veins in the soles of her feet.

Seeing her repeating her steps yesterday, Ryan said: "Young man, I have seen all these positions. If there are pinholes, it is impossible to escape my eyes."

There are indeed no suspicious pinholes.

Su Xuezhi didn't say anything, so she asked her assistant to help her, opened the eyelids of the deceased, took a container and stabbed the eyeballs, and extracted the vitreous body.

When the corpse is rotten, the alcohol produced in the body will affect the detection results of the alcohol content in the blood.

Or, in another case, the body after antiseptic treatment is encountered.

In these two cases, in order to obtain relatively more accurate detection results, there is another way, which is to use the vitreous body of the eye to replace the blood for detection.

The changes in alcohol concentration in the vitreous body usually delay about one to two hours than the blood content. Forensic doctors can use the results of the vitreous body to understand the alcohol intake status within one to two hours before death, and based on this, they can judge the alcohol concentration in the blood at the time of death.

Seeing her pulling substance from the eyes of the deceased, Ryan looked and frowned: "Young man, what are you doing?"

Su Xuezhi explained the principle and said, "If you are skeptical about this, you can verify it in the laboratory after you go back. I think that the test mice should have similar circulatory changes, just like the human body."

Her tone was so sure, Lawn glanced at her, spread her hands and shrugged.

Su Xuezhi brought the samples and the other blood samples taken for comparison, went to the hospital's laboratory to conduct on-site testing of alcohol content.

In this era, the method used to detect alcohol content is a chemical method.

Test with a strong oxidant potassium dichromate solution. If alcohol is contained, the color of the solution will change from orange to gray-green after heating. The thicker the color, the greater the alcohol content.

She tried the first sample first, mixed and heated, and the color of the mixture did not change.

Then, she tried the second sample, and the same result was still the same.

The third blood sample obtained the same result as Raun yesterday, and the color changed to gray-green, indicating that it contained high concentrations of alcohol.

Needless to say, everyone present understood such a contradictory result.

Assuming that her new test method is scientific, it is obvious that the Fu family's eldest son had never drunk any alcohol in the two hours before his death.

The high concentration of alcohol in his blood entered his body by artificial injection!

Mr. Lawn shouted, "This is so strange! You have checked just now that there are no pinholes on the body of the deceased!"

"Xiao Su, could it be your method not enough to explain the result?"

A doctor asked.

He Hanzhu looked at her.

Su Xuezhi pondered for a moment, suddenly thought of a location and immediately returned to the morgue.

She raised the deceased's arm and looked at the underarms.

The deceased had abundant body hair, but his armpits were clean and looked like he had just shaved.

"Mr. Lawn, did you shave it yesterday?" she asked.

"No! It was gone yesterday!" the British answered.

Su Xuezhi carefully checked the armpits on both sides, and soon, in a deep fold in the armpits on the right armpit, he found a cluster of pinholes.

Although it is not very obvious, it can still be seen that there have been more than once punctures here.

She signaled the doctors to come forward to observe.

"Oh my God! The underarm vein! Who is this murderer? How could he think of injecting it in this position!"

The British exclaimed on the spot.
