I'm a delivery man, it's reasonable for me to be at the crime scene

"Jiang Chen, is there anything unusual about the shield you found?" Wang An handed him back the cigarette.

"Some words, it may be a trick between lovers. "

"Then why do you check your fingerprints?".

Jiang Chen's intuition was telling him that there was a third person's fingerprints here, and the murderer was wearing gloves to commit the crime throughout the whole process.

According to that sentence, with a strong backing, this Wang Xiaoze must know the murderer.

"Because there are too many doubts, check his social circle. "

Jiang Chen said as he walked out the door and lit a cigarette.

At this time, the phone rang, he saw the caller ID, and did not hesitate to follow.

"Xiao Liu, what did you find?".

"Lin Qiuru has a problem with the timing, when she went out in the afternoon, there was an hour of free time and she didn't go to work in the hospital. "

Jiang Chen sighed and looked at Wang An thoughtfully.

"If Lin Qiu is suspicious, go and interrogate first. "

"Hmm. Wang An didn't take a few steps, turned back again, and said softly: "Is the murderer so powerful?"

"Because of a head injury, you can strangle the other party, or even ......" Jiang Chen didn't say a word.

He's speculating on something unpredictable.

Wang An really clenched his back molars, there is always one kind of people who are in a hurry to die in this world, and he won't say half of it.

"Go and interrogate Lin Qiuru first, you stay at the scene of the crime and look for clues. "

Jiang Chen shrugged his shoulders and had no choice but to stay here.

Delivered a day of takeout, and could only sleep at the staircase.

The officer guarding the gate said, "Aren't you going home?".

"The leader's order cannot be resisted. Jiang Chen smiled bitterly.

It's just the dead of night, and I can calm down and think about some key points, the shield and the motive for the crime.

There is also a sofa cabinet that has been moved, but there is no blood on it.

He stood up and walked to the safety staircase, wanting to light a cigarette, but the voice-activated light was not in a hurry, and the lighter burst out with a "snap".

With the help of the lights, I saw a black plastic bag on the ground.

Jiang Chen subconsciously thought of something.

Squatting down and touching something, there was a crackling sound, a crisp ceramic crashing sound.

When I opened it with gloves, I saw that there was a broken vase of water, which meant that it was smashed into the victim's head.

The murderer was actually placed here?

This made him a little confused when he arrived, didn't he take it with him? or did he deliberately stay for people to find out?

Jiang Chen called someone to come over and take these for testing.

Now I'm going back to the criminal investigation.

......

As soon as he walked into the police station, Wang An also walked out, his face full of melancholy.

"What's wrong? Jiang Chen asked.

Wang An sighed: "Lin Qiuru didn't go back to the community, and the people who were filmed by the surveillance video never came back." "

"And had lunch at a convenience store. "

Jiang Chen said again: "The murder weapon has been found, and it has been taken for testing." "

"Okay, you go and rest first. "

Jiang Chen did not go to rest as he instructed, but went to see Lin Qiuru for dinner.

It's been a long time to go to the convenience store for an hour.

And she was still a nurse on duty that day, so it was impossible for her to leave her post for too long.

It must be a little quirky.

All night, the police station was busy, except for the busiest large group, the second belonged here, the criminal investigation brigade.

Jiang Chen yawned and was doing a criminal profile.

Looking carefully, Lin Qiuru on the screen stuffed a bite of food and looked at the phone again.

As if confirming something.

Zoom in and see it's just a simple work exchange.

At dawn, Jiang Chen's eyes were sour, and the table was full of his own cigarette butts.

A pack of cigarettes is almost gone.

Wang An walked in with a tired body and asked suspiciously, "Why haven't you slept yet?"

"Found something. "

He enlarged the screen, it was Lin Qiuru's mobile phone WeChat, slowing down fifty times.

Lin Qiuru's fingers slid quickly, deleting a person's information.

"Check her phone to see who she is chatting with. "

Jiang Chen yawned and patted him on the shoulder.

"All in all, Lin Qiuru can't let it go for the time being, and he will talk about it until the water comes out. "

Wang An saw the cigarette butt on the table, good guy, you smoker, you are really addicted.

"Smoke less, the lungs will be bad in the future, and it will be difficult for the criminal police brigade to enter. "

Jiang Chen smiled and didn't speak.

When a man thinks, he is tired and relies on cigarettes to wake up.

Dozed off on the couch.

He is building a crime template in his head, which is a skill given by the system.

A scene takes the perspective of the deceased.

Wang Xiaoze was doing something when he heard someone open the door, and he saw a familiar face.

Immediately after turning his back to him, the murderer took the vase from where and smashed it at the victim.

Then strangle the other party with hemp rope.

The process lasts for a few minutes, and it is performed in one go without deviation, and it is quickly and accurately expressed.

"Morning, Xiao Chen...... Wake up. Wang An patted him on the shoulder.

Jiang Chen opened his wistful eyes, the light pierced his eyes, and it turned out that before he knew it, it was already dawn.

"Coffee, have you woken up? "

"Well, who's the one who deleted it?".

"Her best friend Amei. "

Jiang Chen took a sip of coffee and asked, "What about the result of interrogating Lin Qiuru?"

"She said something bad about her husband, then she deleted it, and now she is recovering the chat history. "

Wang An said heavily.

Jiang Chen always felt that some details had been overlooked.

"Fingerprints, the shield has the fingerprints of a third person. Xiao Zhe, a police officer from the technical department, spoke.

Everyone turned their heads to look at him.

Jiang Chen smiled, there were still five days left before the case was solved.

(The first case is easier to guess, but not later...... ）
