Half past four in the afternoon.

More than five hours have passed since Zhao Chengbi's family of four was killed.

The suspect, Zhao Chengjin, has also been taken back to the police station by the police.

After some strict interrogation, Ning Yelei still felt that the other party was very suspicious, but he couldn't ask anything useful from the other party's mouth.

Zhao Chengjin always insisted that he just rushed to his parents' house this morning, and after taking his things, he went directly back to his house.

did not kill his parents, brother and sister-in-law, and I don't know why this family suffered such a tragedy.

Ning Yelei looked at Zhao Chengjin, who had been acting very indifferent during the interrogation, and became more and more suspicious in his heart that this cold-blooded woman was the murderer.

Normal people, after learning that their parents and brother were killed, should be sad first reaction.

But Zhao Chengjin first asked the other party about the time of death and the method.

And she only showed a hint of surprise when she learned that an eyewitness saw Kong Yanlan fall to her death.

The rest of the time, she was like a passerby who heard a stranger's story.

Moreover, that cruel story still failed to resonate with her at all.

"Zhao Chengjin! The evidence is overwhelming, do you still want to quibble? Ning Yelei directly threw a pile of materials in his hand onto the table in front of Zhao Chengjin, "Zhao Chengjin, the scratch on the left arm of the deceased Zhao Chengbi, we detected the dander that belonged to you, how do you explain?" ”

Judging from the results of various examinations, many fingerprints belonging to Zhao Chengjin were also found in Zhao Chengbi's home, especially in the scratched wound on the left arm of the deceased Zhao Chengbi, dander belonging to Zhao Chengjin was also detected.

"I had an argument with him because of some things, and he stopped me when I wanted to leave, so I didn't inadvertently scratch him." When Zhao Chengjin said this explanation, the emotions on his face didn't seem to fluctuate much.

"Mr. Policeman, just a few scratches can't tell me that I'm a murderer, right?" Zhao Chengjin glanced at the time on the other party's wrist watch, "If, you don't have evidence, please let me go home quickly, I should go back and cook dinner for my son." ”

Ning Yelei was almost so indifferent to the point of arrogance by Zhao Chengjin that he was so angry that he was about to explode on the spot.

This case of murder in the closed room instantly changed from being clear at a glance to being helpless at the moment

At this time, Ye Qingzhou, who had been observing Zhao Chengjin's reaction outside in the interrogation room, walked in with three bottles of water.

She first gave Ning Yelei and another interrogating police officer a bottle each.

Then, Ye Qingzhou put the last bottle of water on Zhao Chengjin's left hand.

"Thanks, if it's okay, I'd rather go home than drink water." Zhao Chengjin glanced at Ye Qingzhou in front of her, but when she was also the same person as Ning Yelei, she didn't have a good impression when she spoke.

"Drink this bottle of water, and you're good to go." No matter what the other party's attitude was, Ye Qingzhou still smiled softly on his face.

"Your police station, now that you can't ask the desired result, have you started to drink obedient water to the suspected?" Zhao Chengjin glanced at the mineral water bottle on his right, raised his eyelids and looked at Ye Qingzhou in front of him, with a smile and mockery on his face.

Ning Yelei looked at Ye Qingzhou's slightly puzzling approach, as well as Zhao Chengjin's reaction, and a thought suddenly flashed in his mind.

"If you're afraid, I'll change it with you!" Ning Yelei jumped directly in front of Zhao Chengjin with the bottle of water in his hand that had not yet been opened, and then picked up her water, unscrewed it and poured a big sip.

Seeing this, Zhao Chengjin's inner vigilance seemed to have relaxed a little at this moment, and she raised her hand to unscrew the cap.

After a whole afternoon of questioning, Zhao Chengjin was already thirsty, and at this time, as soon as she heard that after drinking this bottle of water, she would be able to go home, and she also drank the entire bottle of water directly in a few gulps.

"That's okay, right?" Zhao Chengjin jumped the empty bottle directly in front of him.

"Captain Ning, let them go." Ye Qingzhou looked at the other party's right hand holding the bottle, nodded, and said, "The murderer, there is someone else." ”

Ning Yelei and another subordinate beside him were stunned when they heard this.

They interrogated for an afternoon, but they didn't ask why, Ye Qingzhou was able to conclude with a bottle of water that Zhao Chengjin was not the murderer.

For a while, both of them wanted to stop her immediately and let her speak clearly.

And Zhao Chengjin on the side, there was also surprise on his face that quickly flashed.
