deep white secret

Chapter 77 Is it Suicide or Homicide?
After Xu Jie analyzed his thoughts, he said firmly:

"Now let's officially open a case for investigation. Sun Yaqi's death from a high fall does not rule out foul play."

Xu Jie's words made Ningxia feel a sense of sacredness in her heart. This is the honor and mission that the criminal police work brings to her.

The two people who have been struggling with the clues look at each other silently. What they really want to do now is to unravel the truth.

Ningxia took a deep breath.

"Since we have locked Liu Zhen, let Shi Yihang conduct a peripheral information screening first, and I will take you somewhere."

Xu Jie drove and quickly took Ning Xia to the Jinghai Pharmaceutical Research Institute. Seeing Ning Xia's confused face, Xu Jie explained:
"The researcher here is my mentor and friend, and he is very knowledgeable in pharmacology. I want to hear his opinion on Sun Yaqi's anti-anxiety drug this time."

"Do you still remember the conclusion about Sun Yaqi's blood report in the autopsy report?"

"Well, the toxicology test is negative, and there is a small amount of monoamine oxidase inhibitor."

Xu Jie smiled:

"I admire Ningxia's memory. You are a living computer that I can open at any time."

Xu Jie said, messing up Ning Xia's hair with his big hands.

"Captain Xu!"

Ningxia shouted loudly:
"We're working."

Xu Jie walked out of the car with a smile and opened the door for Ning Xia:

"Let's go meet Meng Fanlin."

When Xu Jie and Ning Xia walked into the laboratory, Meng Fanlin was immersed in bottles and jars.

Seeing Xu Jie, Meng Fanlin raised his head and glanced up, then immediately lowered his eyes:
"Wait for me five minutes."

After saying that, he continued to play with the experimental equipment in his hands.

Ningxia looked at this place curiously. There were two rows of operating tables filled with various instruments and equipment.

There is a shelf on the west side with various medicines on it. The table in the room is piled with books. In the trash can in the corner are various fast food boxes.

Xu Jie said softly:
"Meng Fanlin is three years older than me. He puts all his energy into research, especially in toxicology and pharmacology. He has published very influential articles in various academic magazines."

Ning Xia nodded, Meng Fanlin deserves to be admired.

"Don't praise me, it's useless. What kind of wind brought Captain Xu here?"

Meng Fanlin buried his head in the console, and when he heard what Xu Jie said, he teased him in a low voice.

"I have nothing to do without going to the Three Treasures Palace. I have a question about medication for anxiety disorders and I want to learn from you."

Upon hearing this, Meng Fanlin became interested, and his eyes hidden behind his spectacles sparkled.

"murder?"

Xu Jie smiled:

"It's up to you to analyze it."

Meng Fanlin hurriedly walked out from behind the console and walked to Xu Jie in a few steps:

"Is there a challenge? Are you stumping Captain Xu?"

"It's very challenging for me, but it might be easy for you."

Meng Fanlin folded his arms and said:
"Say it quickly."

"A small amount of monoamine oxidase inhibitor was found in the autopsy blood of the female deceased."

"Have any questions? Did the deceased have mental problems? Monoamine oxidase is a natural enzyme present in the human body. It mainly catalyzes the oxidative deamination reaction of monoamine substances."

Xu Jie shook his head:
"To explain the academic question simply, what does it mean to detect a drug with this ingredient?"

"It means that the deceased had a mental illness and was undergoing treatment."

"specific?"

“Depression, anxiety….”

Seeing Xu Jie's expression changed, Meng Fanlin immediately explained:

"The human body contains two types of monoamine oxidase. Monoamine oxidase inhibitors inhibit the oxidation activity of monoamine oxidase on monoamine substances, thereby reducing or eliminating diseases caused by the reduction of monoamine substances or excessive monoamine oxidase activity caused by various reasons."

For the first time, Ning Xia listened to other people's words as if they were listening to a book from heaven. Meng Fanlin could pronounce these difficult-to-pronounce names without missing a word, and Ning Xia was extremely impressed.

"Okay, look at the drug names I recorded. Are they all of the same category?"

After Xu Jie finished speaking, he opened his notebook and tore off the paper recording Sun Yaqi's medication.

"Look at these, are they all anti-anxiety medicine?"

Meng Fanlin only glanced lightly and said sternly:

"Who prescribed this? How can these two medicines be used together?"

"something wrong?"

Xu Jie and Ning Xia asked at the same time, and then Meng Fanlin saw Ning Xia standing next to Xu Jie.

"who are you?"

"My girlfriend. Policewoman from the Criminal Investigation Team, Ningxia."

Xu Jie introduced her naturally, and suddenly revealed the identity of Xu Jie's girlfriend, which made Ning Xia feel tight.

"good very good."

Meng Fanlin said three words, pushed up his glasses and pointed at the Paroxetine Sun Yaqi was taking recently:

"These two drugs should not be taken together."

Meng Fanlin was a little anxious:
"Is this how the deceased died? Who allowed him to eat? Isn't this harmful to others?"

"What happened? Please tell me in detail, but this is not the cause of death of the deceased. The deceased fell from a height."

Unexpectedly, Meng Fanlin's eyes widened and he patted Xu Jie:

"That's it. If these two drugs are mixed, people will become hallucinogenic, restless, and in severe cases may even have suicidal tendencies."

Ning Xia was heartbroken when she heard this. She originally wanted to find evidence that Liu Zhen murdered Sun Yaqi, but why did the case turn back to suicide?
Xu Jie obviously didn't expect it either:

"Let's start again. Are you saying that taking two drugs at the same time will make people suicidal?"

"Ah."

"But the autopsy found no ingredients in paroxetine."

"The half-life of Paroxetine is very short and it will degrade within 24 hours after entering the human body. Moreover, if the two drugs are taken at the same time, they are not taken together. Problems will occur within two weeks."

Xu Jie understood now:
"But if you go to the hospital for treatment, the doctor will definitely tell you."

"Yes. These two medicines are strictly forbidden to be taken together."

Xu Jie looked at Ningxia:

"What Liu Zhen means is that Sun Yaqi no longer follows the doctor's advice in the later period. Is she taking medicine indiscriminately?"

"If this happens and our investigation fails again, will Sun Yaqi commit suicide?"

Meng Fanlin's explanation made Xu Jie very confused. The case was not clear, but he couldn't understand it even more.

Meng Fanlin saw the sad faces of the two people, hugged his shoulders and said again:
"I don't understand your case investigation, but as long as the medicine is used, the doctor will definitely inform you in detail, so many people will know that... if it is murder, you can trick the deceased into taking it."

Meng Fanlin's words once again raised the possibility that Liu Zhen might commit a crime.

"Liar? You won't find out?"

"It's entirely possible to take it with food."

"In other words, the deceased took paroxetine first, and then took monoamine oxidase inhibitor drugs two weeks later. During the autopsy, because paroxetine had been metabolized, only the monoamine oxidase inhibitor component could be found?"

Meng Fanlin happily patted Xu Jie on the shoulder:

"If Team Xu comes to our institute, he will definitely research more things."

Seeing that Xu Jie and Ning Xia no longer had any doubts, Meng Fanlin immediately returned to the operating table and immersed himself in the experiment:

"You go, I won't see you off, just close the door."

Xu Jie pulled Ning Xia out of the laboratory, and the two looked at each other. The case became complicated again.

"Ningxia, what do you think? Is it suicide or homicide?"

"No matter which one, we can't be sure from the medicine alone. We don't know who makes the final decision on Sun Yaqi's medicine. In this case, let's put this point aside and continue to investigate."

After Xu Jie listened, he nodded approvingly.
