Please don't stick to Officer Qi [criminal investigation]

The first case, Happiness Community, suspicious points: the scent of flowers around the deceased, the preservatives in the body, the special method of execution, open music, and roses.

It would be far-fetched to say that the scent of flowers is to cover up the smell of corpses, and the antiseptic is to interfere with the police's ascertainment time.The preservative was just an ordinary preservative, and it could only cause minimal interference with the inspection, not even delaying it for three hours.

And if that's the case, music is at odds with florals and preservatives.Turning on the music, it was clear that he wanted the police to find the body sooner.

The method of execution was also very strange, as if he had some obsession, he wanted to be cut from the chest to the abdomen.

Qi Lin drew this point on a big triangle.

"When do you think people will behave in the exact opposite way?" Qi Lin asked Shi Le.

"Psycho?" Shi Le picked up the spoon and ate all the crayfish inside in one gulp.

"Probably not, such a comprehensive means of dealing with clues should not be made by mental patients." Qi Lin listed a hypothesis: "If you want to drink herbal tea because you get angry, but you buy spicy crayfish, this What kind of psychology could it be?"

Qi Lin's question confused Shi Le.He looked at the Ma Xiao in his hand, and then at Qi Lin, "What kind of psychology is there? Maybe that Ma Xiao was not bought for me to eat, so I can bring it for others. Or it's not because I want to solve the problem. I only drink herbal tea when I am on fire, but I drink herbal tea because I want to eat Ma Xiao and I am afraid that the fire will worsen..."

"Genius." Qi Lin snapped his fingers and continued to write and draw in his notebook, "It turns out that this is what I have been ignoring."

"What did you ignore?" Although it was his own point of view, Shi Le didn't understand what Qi Lin was talking about at all.

Qi Lin explained to him: "I always thought that disembowelling was for killing people, and playing music was for killing people better. But in fact, there is another way of thinking."

He pushed the notebook in front of Shi Le, "If we say that disembowelling is not just for killing people... Does this case become clearer?"

"That's the truth, but why?"

"I don't know for now, but we still have another clue, which is the preservative in his body." Qi Lin narrowed his eyes, "Xiao Wang's first reaction when he saw the preservative was that the murderer wanted to hinder the criminal investigation. If so It would be too stupid for the murderer to choose a preservative that has no effect. But if you think about it another way, didn’t the murderer put this preservative? The amount of preservative is not much.”

"It fell on other objects!" Shi Le didn't have the mind to pick up the skewers anymore, "After killing people, the murderer wanted to take things, but he was not careful—no, the murderer took things from Gao Xiaolong's body, so he had to It had to be disemboweled and taken out of the stomach, and because there were preservatives on it, there were residues in Gao Xiaolong's body!"

The clouds open and the moon shines.

"But what can I get out of my body?" Although one doubt was resolved, other doubts surfaced.Shi Le patted his stomach for a moment, then asked doubtfully, "Poop?"

"How could it be something like this? You don't have a brain in your words." Qi Lin just wanted to bite the beef skewers, but when he heard Shi Le's words, he lost his appetite, and put down the bamboo sticks again, "Call the king to check and find out."

"Senior Wang Xin said that food preservatives. Isn't it only available in poop?" Shi Le muttered.

The king's call back was quick, "Wang Xin's judgment was wrong. I just checked again. It's not a food additive, but a preservative to prevent wood from decaying."

wood?Swallow wood?

Qi Lin thought about it all night, but he couldn't understand what Gao Xiaolong swallowed, and why the murderer had to take it out.

He remembered his initial remarks again.

Gao Xiaolong may have played the role of the murderer in other cases.

……

When he arrived at the police station the next day, Gao Xiaolong's parents came again.

This time they came to collect the corpse.The king worked overtime last night to collect all the clues on Gao Xiaolong. Now that Gao Xiaolong no longer needs to stay in the cold storage, he contacted the family members to take away the body.

"After all, the cost of the freezer is quite expensive, so use as little as possible." This is the original words of the director.

The condition of the old couple today is better than yesterday, perhaps because they have accepted the fact that their son has left.

"Officer, you don't know, my Xiaolong used to be very good, and he was not skinny at all." While waiting for the king to send the body to be cremated, the old woman couldn't find anyone to confide in, so she grabbed Shi who was beside her. happy.

Shi Le is really a good listener, he has a gentle temper, and when he hears some bad things, he will be by his side to comfort him.

"I really don't know why he suddenly made enemies. I said a long time ago that he doesn't want to play with those cronies. Now it's over. All three of them were approached by the enemies." The old woman sighed bitterly, "If Xiaolong hadn't been let Would it be better if I went to a technical secondary school..."

This actually has nothing to do with high school.Qi Lin said in his heart, but he didn't break through the old lady's last fantasy.He knows that people in grief need a virtual straw to tie them to, or they risk being swallowed up by empty self-blame.

But he still asked one more question: "What major did Gao Xiaolong study in the technical secondary school?"

"Auto repair, he insisted on learning. He had already gone to the beauty salon, but it didn't take long before he said he wanted to learn auto repair. The child's father spoiled him again, so he followed him when he said he wanted auto repair." The old woman Squinting his eyes, he found a photo of Gao Xiaolong in technical secondary school from his mobile phone and showed it to Qi Lin.

Because it was taken against a paper photo, it was not so clear. I could only vaguely discern that Gao Xiaolong was standing on the far right of the last row.

Qi Lin took out his mobile phone and took another picture of the old woman's mobile phone.

"Thank you, this may come in handy in the future." After Qi Lin finished speaking, the king came up from the first floor, holding a black box on his chest.

That was Gao Xiaolong, who locked his accumulated life in a small box.

"Officer, please catch the murderer." The old woman bowed to Qi Lin and Shi Le with tears in her eyes, and was supported by her wife tremblingly out of the police station.

At this moment, Qi Lin's pocket vibrated, it was a call from Xiao Wang.

"Hey, how was your vacation? Where did you go?" Qi Lin asked after picking up the phone.

Xiao Wang was silent for a while, "Qi team, I'm at the scene of the first case."

"Didn't he want to take a good rest?" Xiao Wang's lingering voice leaked from the receiver, and Shi Le interjected after hearing it.

"It's not to make Team Qi so tired." Xiao Wang laughed twice, "But Team Qi, will you listen to my new discovery?"

"What did you find out?" Team Qi hated other people's secrets, "If you want to say it, say it quickly, if you don't say it, forget it."

"Then I really want to tell you, don't be scared," Xiao Wang cleared his throat, "I found Zhao Yutang's fingerprints in the range hood in the kitchen."

"This doesn't mean anything. The two are friends, and it's normal to leave fingerprints."

"But that's a range hood, with some greasy dirt on it. The latest greasy dirt should be left at [-]:[-] noon on the day of the incident, but Zhao Yutang's fingerprints were not covered by the fumes." Xiao Wang paused, "Qi Team, do you understand?"

Now, all the clues form a circle.The three murder cases were finally linked more tightly.When facing interrogation before, Zhao Yutang once said that he had been sleeping at home on the day of the crime, but the fingerprints left by him overturned his statement.

He must have been to Gao Xiaolong's house for some reason.

"I'll go to the scene of the crime again." Qi Lin picked up the car keys and left Shi Le where he was.

Shi Le is still immersed in the reasoning just now.

"How can senior react so quickly?" He asked the king.

"If he doesn't react quickly, he won't be the Qi team." The king pushed the glasses frame on the bridge of his nose, "Qi team used to be a famous figure in the police station. It is said that he solved a big case when he was still in school. When he arrived at the police station Afterwards, his detection rate reached [-] percent."

"Huh? Is it so powerful?" Shi Le raised an eyebrow, "Jiangcheng University has produced such a strong senior."

At this moment, the king said, "How do you know that Team Qi belongs to Jiangcheng University? You knew him before?"

"Ah, no." Shi Le waved his hand, "I guess."

But this reason could not convince the king, "If you want to guess, you should guess Qingcheng Police Academy or some other police academy. How can you guess Jiangcheng University?"

Fortunately, there was someone else named Dawang, so Dawang didn't continue to pursue what Shi Le didn't say.

Shi Le shrugged and caught up with Qi Lin.

When I went to the happy community again, it seemed that the happy community had returned to peace.It was only a day before the murder case, and the same group of people watching the excitement downstairs had already danced in the square, and the topic of people's mouths had changed from the case to the family's gossip.

Qi Lin took the elevator to the twelfth floor, and Xiao Wang was already waiting outside the door.

"Qi team, this is here." Xiao Wang pointed to Qi Lin to see where the fingerprints on the range hood are, "Look, this is the diagonal one."

Qi Lin bent down, trying to restore Zhao Yutang's posture at that time in his mind.

The fingerprint appeared obliquely on the inside of the range hood, so the fingerprint itself was not complete, only half of the fingerprint on the right side of the thumb of the right hand, and the part near the fingertip was obviously more blurred, and the part near the joint was also obviously curved, which shows that Zhao Yutang It should be that he put his hand on the range hood naturally.

"What were you doing here?" Qi Lin put on his gloves, and re-imitated the movements that Zhao Yutang might make with his big hands, "There is obviously nothing on the right side, why do you hold it like this?"

Shi Le also thought of this, "At that time in the interrogation room, Zhao Yutang took cigarettes..."

A picture rushed into Qi Lin's mind.

In the interrogation room, Zhao Yutang touched the cigarette with his left hand.

Zhao Yutang is left-handed!

He followed his gaze to the left of the stove, where there was a wooden knife holder with four shining knives on it.
