Chen Weibin looked up at the wall clock on the wall, it was almost six o'clock in the afternoon. Then, Chen Weibin looked out the window again, the sun was shining, and the sky was still very bright, so he asked: "During this time, when will it be dark until it gets dark?" ”

"It's the height of summer, and it's a sunny day today, and it's going to be dark at eight o'clock." Wu Lei responded.

"Good! Make it! Chen Weibin slapped the table and continued, "Li Jun, immediately gather everyone who is still in the detachment, set off immediately, and go to the place where the little thing fell together!" ”

"Yes." Li Jun replied as he went out to say hello.

Half an hour later, Chen Weibin led more than 20 policemen from the detachment to the weedy field under the fort next to the section of road he had been on at noon.

"Let's look for and see if there is anything in the weeds, you must be careful and careful." Chen Weibin shouted loudly.

"Yes." The crowd responded.

Then, everyone put on plastic gloves, bent down, and searched out from the innermost part of the fort, not sparing a single grass.

An hour later, Li Jun suddenly stood up, held a small object in the air in his right hand, and shouted excitedly: "Detachment Chen, come and see, is this what was thrown out of the car?" ”

Chen Weibin immediately stepped forward, took the thing in Li Jun's hand with his right hand with plastic gloves, and looked at it carefully, it turned out to be an insulin refill! Chen Weibin's heart suddenly swelled with waves!

This is a new discovery! Chen Weibin slowly turned the refill, found the barcode on the outside of the refill, and found a small English capital letter D in the middle of the numbers below the barcode! Although the refill has been washed away by several months of rain, the letter has become a little lighter, but the shape of the letter is still basically clear, and it is really not easy to see if you don't intentionally check it.

"Let's look carefully and see if there's anything else." Chen Weibin said loudly.

Then, Chen Weibin took out a plastic bag from his left trouser pocket, filled the refill, and put it back in the left trouser pocket. Then, Chen Weibin lit a cigarette, looked up at the guardrail above the fort, and then turned to look at the camera that was observing the subsidence of the road surface, and couldn't help but show a smile.

Another half hour passed, and no one found anything special except for some confetti.

"Wrap up! Great work, everyone! Chen Weibin took everyone back to the criminal investigation detachment.

Chen Weibin sat on the sofa in his office, took out a plastic bag containing a refill from his trouser pocket, put it on the coffee table, and fell into deep thought. The mark on this refill is basically the same as the mark on the snake venom refill that Yu Qianqian confessed, could it be that this refill is the snake venom refill that Yu Qianqian gave to Zhou Yuanliang? Previously, in the video, he saw a small thing thrown out of the car, Chen Weibin was a little skeptical at the time, it can't be so coincidental, that thing is a pen refill, right? Now it seems......

Chen Weibin immediately called Wu Lei and asked him to take the refill in the plastic bag to the comrades who did the inspection to check it immediately, find out what was in the refill, and at the same time extract all the fingerprints on the surface of the refill.

It was nine o'clock in the evening. Chen Weibin felt a little hungry at this time, so he went to a noodle restaurant outside the detachment to eat a bowl of small noodles, and returned to the office to wait for the test results.

At half past eleven in the evening, Wu Lei ran into Chen Weibin's office out of breath with the inspection report, and said excitedly: "The results are out!" ”

When Chen Weibin heard Wu Lei's tone, he felt that there must be something important, and hurriedly asked, "How is it?" ”

"That refill contains not only insulin, but also king cobra venom!" Wu Lei said quickly while handing the report to Chen Weibin.

"Good!" Chen Weibin said happily while reading the report, clenching his fists.

Wu Lei added: "The fingerprints on the surface of the refill have also been checked, but because it has been almost three months, the surface of the refill has been washed by rain and climbed by mosquitoes, and the fingerprints on it have been very blurry and incomplete, and it is really impossible to compare whose fingerprints it is." ”

Chen Weibin nodded and said, "You go and bring that refill, then get the car ready, and go with me to the sub-bureau detention center." ”

"Okay. But...... When I checked it just now, the king cobra venom in the refill has been extracted and preserved, and now, the refill is empty, do you still want to bring it? Wu Lei asked.

"If you want to bring it, you can do it."

"Yes." Wu Lei agreed and went out.

When Chen Weibin and Wu Lei arrived at the detention center, it was past midnight, and Chen Weibin asked the police at the detention center to take Yu Qianqian into the interrogation room.

Chen Weibin took the empty refill in a plastic bag, walked next to Yu Qianqian, showed the refill in front of her eyes, and asked, "Is this refill the one you gave to Zhou Yuanliang?" ”

Yu Qianqian looked at it carefully, nodded, and said, "It should be." In the middle of the numbers below the barcode, there was a capital letter D, which was not very clear, but I still recognized it, and it was most likely the one I gave him. ”

"How many refills did you put a D on in total?" Chen Weibin asked.

"I've only marked one, and the others are gone." Yu Qianqian shook her head.

Chen Weibin didn't say anything, took the plastic bag, turned around and walked back to the chair opposite Yu Qianqian and sat down.

Yu Qianqian looked at Chen Weibin and asked, "Captain Chen, didn't you get this refill a long time ago?" I found it at Zhou Yuanliang's house, right? ”

Chen Weibin also looked at Yu Qianqian, but still didn't speak.

"Just now, I saw that the inside of the refill was empty, and it seems that Zhou Yuanliang must have used it. Ay...... He really died at my hands! Yu Qianqian sighed and sat down on the interrogation chair.

Although Yu Qianqian gave the snake venom refill to Zhou Yuanliang, Yu Qianqian did not see Zhou Yuanliang use the refill, in her heart, out of the desire to survive, she always held some luck, hoping that Zhou Yuanliang did not use the refill, then she might not be sentenced to death.

At this time, Chen Weibin suddenly raised his voice and asked seriously: "Yu Qianqian, tell me honestly, that night, in addition to giving a refill to Zhou Yuanliang, did you poison what Zhou Yuanliang ate and drank?" ”

"What do you say? I don't quite understand what you mean? Yu Qianqian was a little dazed.

Chen Weibin slowed down his speech and said slowly: "You heard clearly, let me ask you, did you poison what Zhou Yuanliang ate and drank?" ”

"This ...... I didn't, I really didn't! Yu Qianqian was a little anxious, and then said, "I confessed that day, except for giving Zhou Yuanliang snake venom refills, I didn't do anything!" ”

Chen Weibin looked at Yu Qianqian expressionlessly and did not speak.

At this time, Yu Qianqian smiled bitterly and said slowly: "Captain Chen, I'm ...... I'm not even afraid of death, how can I lie to you? ”
