I'm a criminal investigation major, and you want to take me to fight drug trafficking?

"Xiao Zhang, extract the residue from the deceased's vein immediately and examine it immediately."

Qin Shi came to his senses and shouted loudly.

"is teacher!"

The young forensic doctor whose name he called immediately started working.

Qin Shi led everyone back to the door and waited.

"Don't worry, Xiao Zhang is my last disciple. There won't be any problem leaving this job to him."

Qin Shi said as he looked at Zhou Ming and Wang Qingshan pacing back and forth.

Then he looked at Li Xuan and asked.

"Li Xuan, Xiao Li, right? How did you come up with this?"

Li Xuan said.

"I'm just curious, why did the murderer pour blood at the scene of the body disposal?"

"Blood at the scene?"

Qin Shi was moved again. He stared at Li Xuan and exclaimed.

"The blood at the scene doesn't appear to be from the deceased."

"Probably!"

Li Xuan nodded and continued.

"No, it could be the deceased."

"But it's also possible that the deceased was drawn out before death."

"Of course, I think we can only know the answer after we find the murderer."

Qin Shi nodded and said.

"We didn't find any traces of drugs in the blood at the scene."

"It only means that the blood has nothing to do with the time of death of the deceased."

As he was speaking, a man came out from the testing center next to the autopsy room and shouted.

"teacher!"

It was the young forensic doctor called Xiao Zhang by Qin Shi.

I saw him walking over hurriedly with a list in his hand and saying.

"Teacher, a trace amount of drug ingredients was found at the intravenous injection site."

"It's partly anti-inflammatory, and contains a trace amount of Valium."

A tranquilizing ingredient?

Everyone was so frightened by these four words that their pupils suddenly contracted.

This proves that Li Xuan's guess was completely correct.

The drug remains at the site of intravenous injection, and the blood will quickly digest the drug residue because it is quickly drained.

If this evidence had not been presented by Li Xuan, it would have been missed.

"Well done, young man!"

Qin Shi patted Li Xuan's shoulder.

Li Xuan waved his hand quickly and said.

"Senior, you are too kind. We still have to work hard until we find the murderer."

Then he looked at Zhou Ming and Wang Qingshan and said.

"Captain Zhou, Deputy Wang, we now have another target for investigation."

"That means all the major hospitals and clinics in the city."

"We now have very strict controls on medical devices."

“Things like this rarely get out.”

"I'm sure the deceased was attacked while he was seeking medical treatment outside."

Zhou Ming nodded and said.

"I understand. Now let them take action."

He immediately ordered his criminal investigation team to take action.

The first thing is to check the usage of the insurance card, and then the hospital medical records.

The Dragon Kingdom's system is here, and these things are actually not difficult to check.

And this is how investigating a case works sometimes, after finding a breakthrough.

Even if all other attempts are blocked, the murderer can be roughly identified by virtue of this one breakthrough.

The other clues were unimportant to them now.

As long as the deceased's medical records are found, perhaps everything will come to light.

Criminal investigation is an art, unraveling the truth.

In this process, many people will become addicted to this feeling.

The moment the mystery is solved, a sense of accomplishment and pride will follow.

It’s like a game where no one else can pass it, but you are the first one to complete it.

Then you become famous all over the world, and that is your sense of accomplishment.

Li Xuan felt that he also liked this kind of detective work that involved unraveling the mystery.

The more complex the case, the greater the challenge, but also the greater the sense of accomplishment.

When the criminal investigation team found the deceased's insurance card usage record.

All the puzzles point to Guangzhou-Shenzhen Third Hospital.

After inquiring in the hospital, the female doctor who treated the victim was found.

The person was brought back on the spot and the interrogation began immediately.

"Wu Ting, according to our investigation, you murdered the deceased Luo Yang on the evening of the 10th. Do you admit it?"

In the interrogation room, the interrogating detective spoke.

Outside the interrogation room, Li Xuan watched the experienced criminal police conducting the interrogation and began to learn from them inadvertently.

These are all interrogation experiences, which may be useful in the future.

"Officer, I don't know what you're talking about."

The female doctor named Wu Ting sneered.

She glanced at the police officer who was interrogating her, then looked at the camera in the interrogation room.

Then he said.

"Sorry, I'm just a doctor."

"I only know how to save people. How could I possibly kill someone? You must have made a mistake."

Wu Ting looked innocent and said, "I will never admit it even if you kill me."

As the situation gradually deteriorated, Captain Zhou couldn't stand it anymore.

Wu Ting has a very strong psychological quality, and ordinary interrogation has no effect on her at all.

Zhou Ming was preparing to conduct the interrogation himself. When he was about to walk in, he glanced at Li Xuan next door.

After thinking about it, he realized that Li Xuan was the leader of the case, and that he should watch his interrogation, so he spoke to Li Xuan.

"Li Xuan, come with me in and ask."

Li Xuan nodded, but followed Zhou Ming in, still a little confused.

"Wu Ting, I'm Zhou Ming, captain of the Criminal Investigation Brigade, and this is Officer Li Xuan. We will be in charge of the interrogation..."

Zhou Ming went in and sat down and read out the clear interrogation regulations to Wu Ting.

Then he signaled to Li Xuan with his eyes that they could begin.

Li Xuan thought for a moment, silently opened the Tingxintong, and asked with a smile.

"Doctor Wu, how old are you?"

Wu Ting obviously didn't expect that Li Xuan's first question would be this.

After a moment of hesitation, he answered.

"27, what's wrong, officer? Does this have anything to do with the case?"

What's wrong with this police officer? Why is he asking my age?

Li Xuan listened to Wu Ting's answer and thought of what she was thinking.

Then, Li Xuan's expression suddenly changed and he asked seriously.

"Wu Ting, you're so resourceful. You thought you could destroy the drug residue by injecting Valium intravenously and then quickly bleeding it."

"Killed Luo Yang without anyone noticing? What a shame! We found drug residue, it's irrefutable evidence!"

"You can't escape. Confess and you'll get a lighter sentence."

The confidence on Wu Ting's face gradually began to disappear as Li Xuan spoke, and her inner defenses began to collapse bit by bit.

How did he know I was using Valium? He didn't know I extracted the Valium from sleeping pills from the pharmacy.

[Yes, he's trying to trick me. I can't panic. Damn Luo Yang! I can't go in.]

After a moment's silence, Wu Ting slowly spoke.

"Officer, you must have misunderstood me. I didn't..."

Before Wu Ting could finish her words, Li Xuan interrupted her.

"Did you think we wouldn't be able to find the tranquilizer component extracted from sleeping pills?"

【How come he knows everything! 】

Li Xuan kept listening to what Wu Ting was thinking.

【...】

As the intensity of Li Xuan's interrogation gradually increased.

Gradually, Wu Ting's logic began to become confusing.

Many times the information is completely irrelevant.

Finally, after Zhou Ming scolded her several times, Wu Ting could no longer bear it. Tears flowed from her eyes and she began to sob.

It took about three minutes.

She raised her head sharply and screamed hysterically.

"He deserves to die, he deserves to die!"

"Yes, I killed him. I wanted to cut him into pieces."

The angry roar echoed throughout the interrogation room.

Wang Qingshan and others who were watching the interrogation outside heard it clearly.

After Wu Ting gradually calmed down for a while, Li Xuan spoke.

"Tell me, what's going on?"
