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

In the autopsy room of the Yanjing Public Security Bureau, the air was filled with a slight smell mixed with formalin and disinfectant.

The cold light from the shadowless lamp focused on the stainless steel dissection table in the center, where Xu Sheng's body lay quietly. His skin had now turned a lifeless waxy yellow.

"Wait for me outside!"

Before Li Xiangnan entered the house, he asked Song Zimo to wait outside. The young man had never seen such a tragic situation, and he hoped that he would never come into contact with such a thing!

"Then I'll wait for you at the door!" Song Zimo was very tactful and sensible, and immediately understood Brother Nan's concerns.

Li Xiangnan nodded and pushed open the heavy soundproof door. Forensic Doctor Wang was standing in front of the sink, carefully cleaning the blood stains from between his fingernails with a brush.

"Are you here?" Forensic Doctor Wang said in a tired and hoarse voice without even turning his head. Although he was over fifty and most of his hair was white, his eyes that penetrated the thick lenses of his glasses were still as sharp as a falcon!

"Thank you for your hard work, Old Wang!" Li Xiangnan took out a cigarette and handed it over.

Now that the autopsy is complete, there is an unwritten rule in the autopsy room, which is a tacit understanding between him and forensic doctor Wang over the years.

We must use normal human smoke to drive away the dead air in this room.

Li Xiangnan lit a cigarette and stood a few steps away. He did not go forward to see Xu Sheng's body immediately, but cast his eyes on the stage and observed.

The chest and abdominal cavities of the corpse had been opened, and the organs had been removed one by one, then roughly put back in place after examination.

Now, a suture needle is inserted into the huge Y-shaped suture area. After Li Xiangnan has examined it, Forensic Doctor Wang will ask his assistant Xiaodan to suture the body.

Doctor Wang turned off the faucet, wiped his hands, walked over to the autopsy table, took down the notebook, handed it to him, lit a cigarette, and said directly, "Preliminary conclusion: Xu Sheng died of mechanical asphyxiation, consistent with suicide by hanging! Judging from the condition of the body alone, if it weren't for the few suspicious points we've discovered at the scene, this case would have been closed as a suicide ninety percent of the time!"

This is the value of Li Xiangnan's existence.

It is also the purpose of the establishment of the Forensic Trace Examination Department!

We will not let any case become an unsolved case!

The smoke enveloped Li Xiangnan. He opened the notebook and saw the handwriting of his assistant Xiaodan.

"There's a clear sign of a cervical ligament injury, subcutaneous and deep muscle bleeding, and signs of a fracture in the greater horn of the hyoid bone! All of this evidence is consistent with hanging, caused by the sudden and powerful pull of gravity on the body during the fall!"

Li Xiangnan took a deep breath, exhaled the heavy smoke, raised his feet and sat on the table beside him, reaching out to flick the ash into the flowerpot on the table.

"In addition, I found many pinpoint hemorrhages on the conjunctiva of the eyeballs, and edema and emphysema around the lungs. These evidences also match the symptoms of Xu Sheng's death from asphyxiation!"

Li Xiangnan nodded and said, "Forensic Doctor Wang, thank you for your hard work!"

All this was within his expectations.

Of course, this is enough to show that the murderer who killed Xu Sheng was a master of assassination. He was able to make these things perfectly, so terrifying!

Li Xiangnan put down the notebook and looked up at Forensic Doctor Wang. He knew that there would be a "but" in the next sentence of Forensic Doctor Wang's words.

It was the words he said from now on that were the reason why the other party urgently asked him to come out from prison!

"But!" A tacit smile appeared on Forensic Doctor Wang's serious face. He changed the subject and used his other gloved hand to peel open the corpse's nasal cavity. "Look here!"

Li Xiangnan jumped off the table and took the magnifying glass from Forensic Doctor Wang.

"Look carefully at his nasal mucosa, especially around the middle turbinate and choanae!"

Li Xiangnan nodded and moved closer to observe carefully.

Xu Sheng's body had been left in the August weather for 8-12 hours, and now many spots and rigor mortis had already appeared on the body.

He ignored those things and instead used a magnifying glass to observe the area that Forensic Doctor Wang mentioned.

It can be seen that there are some extremely tiny, dark brown, light granular substances attached to the nasal mucosa.

It was almost identical to the debris they found in the corner of Xu Sheng's cell!

Moreover, these particles are deeply embedded.

"See? These substances weren't acquired after death!" Forensic Doctor Wang said with certainty, "If it was dust floating in the air after death that entered Xu Sheng's nasal cavity, it would only be in the vestibule of the nose!"

Li Xiangnan understood what he didn't say and took over the conversation, "Now these things have appeared deep in Xu Sheng's nasal cavity, and even entered the pharynx after passing through some tissues. This means that before he suffocated, he had actively..."

He thought for a moment, felt that this statement was not comprehensive enough, and continued: "Or, it is the forced deep inhalation that brings these particles deep into the nasal cavity!"

He looked at his notebook and recalled, "The same substance we found in Xu Sheng's cell... Before he died, he might have been forced to smell it, or come into close contact with some burning or ground plant matter!"

This is a very important clue discovery.

This will also directly verify the clues Li Xiangnan had obtained before: there were signs of multiple people in Xu Sheng's cell last night.

Maybe someone forced Xu Sheng to inhale these things, causing him to fall into a coma?

"And stomach contents!" Forensic Doctor Wang walked over to the sample rack nearby and pointed at a row of glassware. "Ever since you requested that the trace examination complete the examination of the contents, I've been doing that every time I perform an autopsy! Now look, I did a toxicology screen, and besides some routine digestive tract findings, I also found this!"

As he spoke, he picked up the test tube, which contained a little turbid liquid.

"I've tested it. It's a compound alkaloid! It has a strong neurological inhibitory effect. It can cause confusion, muscle relaxation, and even..."

Li Xiangnan raised his eyebrows and said in unison with him: "Hallucination?"

"Yes!" Forensic Doctor Wang nodded. "Even though the dosage isn't large, it can definitely cause an adult to lose most of their ability to resist in a short period of time!"

Li Xiangnan nodded. "So, in other words, as we suspected before, Xu Sheng was already in a semi-comatose state before hanging himself. He not only inhaled some particles, but was also force-fed this alkaloid-containing liquid?"

But here comes the problem.

"You want to ask why this is unnecessary, right?" Forensic Doctor Wang saw him frowning. "I've thought about that, too!"

Li Xiangnan nodded.

Because according to the previous logic, Xu Sheng would have fallen into a coma long ago after inhaling the plant powder!

But why is it necessary to continue injecting him with alkaloid venom?

Why bother?

Aren’t you afraid of being discovered?

Wouldn't we know the answer after an autopsy?

Do not!

Li Xiangnan felt that he could not think about this matter with his own way of thinking, but should think about it from the murderer's perspective!

The murderer didn't know that a forensic trace examination department had been established within the public security department!

So he achieved his goal by faking Xu Sheng's death by suffocation!

The two looked at each other and saw the solemnity in each other's eyes.

Now the murderer's modus operandi can almost be restored.

He first used some method to make Xu Sheng drink some kind of poison, and when he gradually lost consciousness, he made him inhale the ground powder and burning of some plant. When he completely lost the ability to resist, he created the illusion of hanging himself!

Or the order may be reversed, but the goal is the same!

The process was neat and tidy, with perfect control of timing and handling of movements!

Now, we need to find a connection, find out why we need to use two things at the same time and what the functions of these two things are.

Are alkaloids hallucinogenic and have lost their resistance?

Does the plant powder cause coma? Or does it have a similar effect to alkaloid poison?

Why do you do that?

Is there any order of precedence?

Was Xu Sheng very alert and realized that the murderer's intention was to kill him, so he resisted and refused to cooperate?

The latter thing is to get rid of him quickly?

Li Xiangnan hasn't figured it out yet.

He looked up and found that Forensic Doctor Wang was hesitant to speak, and his heart skipped a beat.

"Old Wang, do you have any other discoveries?"

Forensic Doctor Wang walked to the side and picked up a report. One sentence shocked Li Xiangnan.

"Remember the ecstasy we found in Xu Sheng's house?"

"..."
