Yuan Mu looked at the small piece of fabric in the photo that could no longer distinguish the color and said, "This is the sleeve ...... of the shirt." ”

Thinking of Luo Li's previous description of the suspect, she asked again, "Is this on the white shirt?" ”

The detachment leader breathed a sigh of relief and nodded, "Yes." And the inspectors have extracted something interesting from it. ”

"Linalool and linalyl acetate."

"What? What is this alcohol and what ester is it used for? A police officer asked.

"This is the main chemical component of lavender essential oil." The detachment leader said calmly.

"It seems that the little girl is right. This time we finally caught his tail. The master sighed, and the look on his face was very complicated. As a criminal police officer, he is naturally reluctant to retire with unsolved cases.

"But DNA alone doesn't mean much to the object. We still don't know who this guy is. Someone said in frustration.

"It's a piece of rotten wood." The detachment leader hated the iron and said: "What does this evidence mean, it shows that Yang Xiu's inference is correct." The Road and Bridge Killer did not grow up in a day, and we only need to re-investigate a few cases in the Road and Bridge area that were suspected of being committed by him to find clues. ”

"For example, Yang Xiu's report on women being sprayed with dye, pricked with needles, tailgating, the theft of a female student's home, and the case of rape are all ...... our breakthroughs."

"It was our negligence before, and we haven't caught the crime, so it's time to give them an explanation."

When the detachment leader said these words, his expression was lonely, his voice was low, and Yuan Mu could feel his self-blame from a long distance.

"Xiao Mu, you call that little girl, and I'll have a good understanding of the situation back then. In addition, Muzi, you prepare, and take her to identify the suspect when the time comes. I always feel that Li Zi'an is not simple. The master also began to lay out the next step.

Just as Luo Li and Ji Si'an were on the way to the criminal police team, the master came to the interrogation room again.

"Li Zi'an, how do you explain to Yang Xiu that you are not the suspect he is looking for?"

Hearing this question, Li Zi'an was stunned for a long time. Yuan Mu stared at him tightly, this was the first time since they interrogated Li Zi'an, he didn't seem calm.

"I ...... As I said before, I'm just throwing the dead animals here that don't work. ”

Li Zi'an's arms contracted, which was a self-protective gesture, indicating that he was beginning to defend himself.

Yang Xiu's report introduced the death of those animals. You're a doctor, and you should know very well that there are indeed many animals that are tortured and killed. The master changed his previous attitude and began to be aggressive.

Li Zi'an's arms tightened a little tighter, and he had already formed a posture of holding his arms around his chest.

"Yes, I can see that. But so what? I didn't do it. ”

"Born in poverty, it is easy to be admitted to a medical university, and if you want to gain a foothold in a big city, you have paid a lot for this goal, right?"

Li Zi'an didn't speak, but the corners of his mouth became tighter and tighter, and he no longer had the calmness he had when he first met.

"I thought you were hiding something, but I never figured it out. Now I suddenly figured it out. ”

The master got up and stood in front of him, and Li Zi'an had to look up to see the master clearly. After realizing that this would increase his sense of oppression, Li Zi'an quickly lowered his head.

"Our medical examiners realized something was wrong as soon as they saw the animal's bones. You are a top student in medical school, and you work so hard, how can you not know it? ”

"Haven't you ever encountered a corpse dumping in the same place?"

After listening to the master's questioning, the corners of Li Zi'an's mouth rose slightly, and his arms loosened slightly. He actually relaxed, and it seemed that the master had asked the wrong direction.

"No, I didn't meet anyone else there. Every time, I left the body and left. I'm not a pervert and don't have a habit of observing corpses. He replied defiantly.

The master realized that he had not guessed what he was hiding from him, and knew that if he continued to ask, he might be led by the nose, so he decisively stopped the interrogation.

"We've definitely missed something......." The master pondered for a while and said, "Xiao Mu, you go and help me bring the previous case files of the Luqiao Killer." ”

When Yuan Mu found the master with the file, he was sitting at his desk and carefully looking at Yang Ping's case materials. When he saw her come in, the master immediately beckoned her over, and after taking the file in her hand, he quickly rummaged through it.

"With ....... This bastard, this time he must be caught. The master clenched his fists excitedly.

"What did you find?" Yuan Mu asked curiously.

Yuan Mu suddenly made a voice and startled the master: "Xiao Mu, you are still there." ”

"Come, look at these files." The master gave up his seat to Yuan Mu.

"The three girls who died before were all strangled to death by hemp rope, but Yang Ping was strangled to death with a round line-shaped leather object. Yang Ping's body was stabbed after her death, and the body was not as clean as before. Yuan Mu pondered the sentence.

"This is all our inference before, what else?" The master guided her.

"Look at the inspection report again."

"The composition of the anesthetic is different." Yuan Mu muttered, not yet figuring out the key.

"The anesthetic he used before was sufentanil for analgesia, and the probofen for Yang Ping was sedative." The master prompted.

"Does it mean that he got the anesthetic differently?" Li Muzi entered the office at some point.

The master nodded appreciatively. "Think about it a little further, where did he get the anesthetic?"

"He has a medical background." Yuan Mu almost shouted.

The master waved his hand and said, "There is another possibility, he knows someone who is engaged in this. ”

"Li Zi'an?!"

"You mean...... Could he be that person? ”

The master said, "This is just my guess. He also needs anesthesia to operate on stray cats and dogs. ”

"I went to look up his previous internship, maybe he got the medicine at that time." Saying that, Li Muzi walked out, and when he arrived at the door, he remembered the purpose of his coming to find his master.

"Look at my brain. Luo Li has come to the criminal police team, and she can arrange for identification immediately. Li Muzi patted his head and said.

"Got it, Yuan Mu and I will take her to identify it."

With the master's words, Li Muzi left with peace of mind.

Luo Li was so nervous that her hands were twisted together, and Ji Si caressed her hands painfully.

"Xiao An...... What if I don't recognize him? Her stomach began to cramp because of the nervousness.

"If you don't recognize it, you can't recognize it, there's nothing. Besides, there is not necessarily a murderer in this. Ji Si'an put his arm around her shoulders and said.

"It's okay if you don't recognize it. I'll catch him with evidence. Yuan Mu comforted.

Luo Li looked at the few people opposite carefully, her gaze stayed on Li Zi'an for a long time, but she still couldn't confirm it. "I think he looks like ...... But it's not like it, sorry...... I don't know. ”

Luo Li ran out crying, accidentally bumped into other police officers, and the materials in the other party's hands fell to the ground.

She frantically helped the other party pick up the materials, and didn't dare to raise her head to apologize.

At this time, Yuan Mu and Ji Si'an came out of the house, and they helped pack up the materials together. When she saw a photo, Ji Si'an was stunned, and she didn't come back to her senses until Yuan Mu reminded her to return the things to the other party.

"What's wrong with you?" Yuan Mu asked in a low voice.

Thank you for the recommendation vote, thank you for your support and collection.
