Rebirth 78, the beginning of the marriage was broken off by the female educated youth

When Li Xiangnan said these words, everyone present was shocked.

He used the results of the trace examination as factual basis to argue with Gao Shi, and with detailed and irrefutable evidence to support his argument, he convinced everyone.

We can also put ourselves in other people's shoes and use the method of substitution to let everyone put themselves in their shoes and imagine if the deceased is their daughter or mother. This way, they can feel the pain of their deceased loved ones.

Finally, the most crucial evidence from the autopsy was taken out, and the cause of death of the deceased was analyzed, which completely convinced everyone.

This debate is well-reasoned, logical, and clear-thinking. It can be said to be extremely beautiful!

Not to mention the people present, although a large group of people, which made up the majority, were already extremely convinced of Li Xiangnan's words, even Gao Shi himself, at this moment, had to admit that Li Xiangnan was right in the face of ironclad facts.

Wonderful!

At this moment.

Guo Qian, who was the first to be hit in the field, felt very happy in his heart. He looked at Gao Shi's face, which was extremely dark, but he could not refute at all. He could only grit his teeth and remain silent. He felt very happy.

I told you to be complacent, to use your status to pressure others, and to negotiate with Director Zhang about the Trace Inspection Department matter without any investigation.

You didn't expect that, not only am I slapping you in the face, but Xiao Qin's partner is also trampling on your dignity!

In the face of these facts, it is useless even if you deny the role of the Trace Inspection Department!

Zhang Tiancheng, who was standing aside, had a very calm expression on his face, but he was extremely shocked and excited in his heart.

really!

This kid Li Xiangnan is really something!

He really has some skills!

I was right to trust him!

The Forensic Trace Examination Department can indeed help the police solve cases. You see, after the autopsy, they did obtain a lot of useful information and even found the key cause of death!

If it weren't for Li Xiangnan's technology, it would be unknown when this unknown female corpse could be buried!

These are the directions that Li Xiangnan and his professional forensic technology have found for our investigation.

Gao Shi, Gao Shi, our police department believes in basing our actions on facts. Now that the evidence is irrefutable, you would be too embarrassed to make a fuss about it, right?

Humph, I'll let you go for now!

Seeing that Deputy Director Gao Shi stopped talking, Zhang Tiancheng, as the director, would naturally not take advantage of the situation at this time to add to the resentment in others.

He exchanged a glance with Gao Shi, half smiling, then turned around and asked with great curiosity:

"Castor bean? Xiao Li, everyone is waiting for you to explain it to us! What is this thing?"

Hearing this name, everyone present was a little hesitant and puzzled.

It’s true that there are all kinds of strange plants, and there are also many poisonous and non-toxic ones. But this castor bean... it really sounds like the seed of some plant. How poisonous can it be to kill people?

"Xiangnan, tell everyone!"

Qin Ruobai, who was standing by, had already poured him some tea to moisten his throat.

Deputy Director Gao Shi was shocked by her partner's words. Not only did she help Captain Guo's career, but she also helped Director Zhang to open up the situation of forensic department construction, and she could also find the truth about the unidentified female corpse. How could she not be happy when she achieved three goals in one go!

In her eyes, Li Xiangnan is now omnipotent, and to say that she admires him to the core is not enough to describe the admiration she has in her heart.

Li Xiangnan took the teacup, took a big sip, handed it back to Qin Ruobai, smiled at her gratefully, then took the tweezers and rummaged through the food residue in the iron plate, and found fifteen or sixteen castor beans that were mostly corroded by gastric juice.

"This castor bean, as the name suggests, is the seed of the castor plant. If used properly, it is a very useful Chinese medicinal material! If used improperly, it is a poison that harms people! The Compendium of Materia Medica records that this medicine can treat hemiplegia, aphonia, deafness, tongue swelling, throat paralysis, shortness of breath, beriberi, toxic swelling, tumors, burns, needle piercing the flesh, retained placenta in women, protruding intestines, and can open the meridians and collaterals, stop all kinds of pain, reduce swelling, remove pus and remove toxins."

"Poison?" Guo Qian scratched his head when he heard this. Although the police often need to have a lot of general knowledge in many fields to solve cases, he really knows nothing about pharmacology. He was a little embarrassed when he heard this, so he had to ask casually: "Xiao Li, do you mean that this female comrade was poisoned to death by eating castor beans?"

Nodding, Li Xiangnan used tweezers to place the eaten castor beans one by one on the iron plate, and also used tweezers to peel out some residues that had been corroded and almost digested by gastric juice.

"Castor beans are rich in ricin and ricinine, a variety of toxins. The former is especially strong, a metabolic toxin! It can directly irritate the gastrointestinal mucosa and damage the kidneys, liver, lymphatic tissue, etc. It can also paralyze the respiratory center. In severe cases, it can induce carbohydrate metabolism disorders, which can endanger life!"

A large group of team members and leaders in the bureau nearby couldn't help but exclaim.

Even Gao Shi was tempted and sweat broke out on his forehead.

If Li Xiangnan had not searched for this information through autopsies, just as he said, it would probably be impossible to get any results even if he searched aimlessly for two years!

Li Xiangnan looked at Guo Qian and Zhang Tiancheng thoughtfully, and found that Gao Shi also frowned, and continued to point at the castor bean and said:

"This stuff, the toxin accumulated to 7 milligrams can be fatal! Look at how many pills are in this woman's stomach? There are already 15 that haven't been digested yet, plus these that have been digested, there are probably at least 20!"

"what?"

There were exclamations of surprise from some lesbians in the room.

Everyone found it unbelievable.

Because a problem immediately arises.

Why did the deceased swallow so many castor beans?

Did he swallow it accidentally, or was he forced to eat it?

If the person swallowed the castor beans accidentally, then the inference of homicide would be overturned. If the person was coerced or tricked into eating the castor beans, then there would be more mysteries involved!

But who knows the toxicity of castor beans?

Everyone began to try to capture the unexpressible inspiration that was on their lips.

"I know!" Qin Ruobai suddenly raised his hand. "To the south! We can look for villages and communes with castor beans to see who has come into contact with this thing recently! There is almost no such thing in Yanjing. If there is any, it must be in the nearby mountainous areas. We can definitely find it by searching!"

Li Xiangnan nodded, praising her for having a direction to think about, but also added: "Many people have accidentally eaten castor beans in the past, especially children! You can go to the commune's health center to ask if anyone has had stomach discomfort or any accidents after eating castor beans! Generally, many of the older generation know that this thing cannot be eaten! This is a direction!"

Everyone present was immediately excited, looked at each other, and finally breathed a sigh of relief.

Unexpectedly, Li Xiangnan's forensic trace examination actually found the direction to solve the case.

However, Zhang Tiancheng seemed to see that Li Xiangnan had something else to say, so he smiled and asked, "Xiao Li, it's okay. Now that we know that castor beans were the cause of the woman's death, you can bring up any ideas you have. You are a forensic doctor, and you are also a criminal investigation consultant in our bureau. Your opinions are also an important reference for the investigation!"

"Okay! Then I'll tell you!" Li Xiangnan put down the tweezers and frowned, "The castor beans were not fried to eliminate the toxicity when they were taken. So, I can't think of anyone else who knows the toxicity of castor beans and how to use it, except for those pharmacies, doctors, doctors, commune clinics, etc. who know the pharmacology and properties of traditional Chinese medicine! Moreover, the amount was so large at one time, and there was so much snow in the mountains, and there was still stock at home. This murderer, let's call him the murderer, must have conditions like a pharmacy at home, or at least a commune medicinal material purchasing station. Similar situations can be investigated in this regard!"

This is another direction of investigation.

Zhang Tiancheng understood why Li Xiangnan hesitated!

The suspicion of the murderer obviously points to his colleague!

As a doctor, it is somewhat difficult to accept when I see my "colleagues" committing crimes.

Those who heal others should not heal themselves, and they should not harm others!

He understood Li Xiangnan's feelings, stepped forward silently, squeezed his shoulder, gave him a comforting look, and then said with a serious expression: "Captain Guo, hold a case analysis and deployment meeting immediately!"

"Yes!"

Guo saluted dryly.

Snapped!

The members of each team in the field stood at attention and saluted, expressing their respect and admiration in their raised right hands.
