"How so?" Fang Xinling muttered.

"You and Xiaonan went to find Wei Yiche that day, did he know that Zhou Changhong made an appointment with Xiaonan to meet?" Li Chengfeng asked with a straight face.

"I know, when Zhou Changhong called, Wei Yiche was also there." Fang Xinling's face was ugly.

To some extent, it was they who inadvertently killed Zhou Changhong.

"Sure enough." Li Chengfeng's eyes froze.

Before rushing to the scene, Fang Xinling and Li Chengfeng temporarily deposited Doudou in the security office of the Chaobaihe villa area, and picked it up when they came back.

"Team Li, if I hadn't forced Zhou Changhong to tell me about Wei Yiqing, Zhou Changhong might not have been killed by the murderer." As soon as Su Xiaonan saw Li Chengfeng, tears couldn't help but fall, and he said with self-blame.

"Silly girl, it's none of your business, why are you crying?" Fang Xinling stepped forward and hugged Su Xiaonan and comforted him softly.

"Xinling." Su Xiaonan hugged Fang Xinling tightly and cried bitterly.

"Xiaonan, it's not your fault, it's my fault, if I could have found out earlier, maybe I could have avoided this tragedy." Li Chengfeng said expressionlessly.

"Team Li, what do you mean by that?" Su Xiaonan was stunned suddenly, and even her tears stopped unconsciously.

"I'll tell you in detail when I go back, and you tell me what you know first."

Su Xiaonan wiped the tears from the corners of his eyes with his hand, and said in a hoarse voice: "I made an appointment with Zhou Changhong to meet in his apartment at three o'clock in the afternoon, and I came over at two fifty, but I didn't see Zhou Changhong until three o'clock, and I was worried that Zhou Changhong might have an accident, so I immediately called him, but no one answered, so I went to Zhou Changhong's house, and his parents told me that Zhou Changhong went out very early, and then Zhou Changhong's father came to open the door with me." But as soon as I entered, I saw Zhou Changhong lying in a pool of blood, Zhou Changhong was no longer breathing at that time, I immediately called the police, and the criminal police of the Wencheng Branch Major Case Squadron rushed over as soon as possible, and they are now inside to investigate the scene. ”

When he heard the Wencheng Branch, Fang Xinling's body stiffened.

"Did he come too?" Fang Xinling asked in a trembling voice.

"Hmm." Su Xiaonan hesitated for a while, but still nodded.

"Xiaonan, do you feel better now? Okay, come with me into the scene to have a look, and Fang Xinling, you can also go in with us. Li Chengfeng said.

"Team Lee, I can do it." Su Xiaonan smiled hard.

"Huh? Why? I'm not a policeman, so I'd better not watch such a bloody picture, I'll just wait outside for you to come out. Fang Xinling asked incredulously.

"You've now participated in the investigation of the Wei family's large-scale murder case as a foreign aid, so I think it's necessary for you to go in and have a look." After Li Chengfeng finished speaking, he took the lead in the apartment, and he didn't even have a chance to let Fang Xinling refuse.

"And that kind of reasoning?" Fang Xinling's mouth opened wide.

"Okay, Xinling, go in, I know you're not afraid of this, could it be that you're afraid of seeing Yan Xiu?"

"How so? Come in, come in! ”

Although Fang Xinling was hard at the mouth just now, she was still apprehensive the moment she walked into the apartment, and she regretted being provoked by Su Xiaonan, she had not completely come out of the sadness of breaking up with Yan Xiu, although she had begun to adapt to life without him in the past few days, but when she thought that she was going to see him later, her heart still felt a faint pain.

The apartment where Zhou Changhong lives has basically been emptied, and it looks empty, only some discarded garbage is still scattered in the living room. Zhou Changhong was lying in the corner near the bedroom covered in blood, the blood on the ground had already coagulated, and several police officers wearing masks squatted on the ground to take pictures.

Yan Xiu and a criminal policeman were discussing in a low voice, when they heard the voice, they raised their heads and looked at the source of the sound, and at a glance they saw Fang Xinling standing behind Li Chengfeng with a complicated expression, and his face changed slightly, but he quickly suppressed the urge to look at Fang Xinling, and took the initiative to step forward and stretch out his hand to Li Chengfeng.

"Hello, I'm the captain of the big case squadron of the Wencheng Branch, Yan Xiu."

"Hello, I'm the captain of the big case squadron of the Liancheng Branch, Li Chengfeng." Li Chengfeng shook Yan Xiu's hand, "Captain Yan, how is the situation of the investigation?" Did you find anything? ”

"Yes, just now I carefully observed the direction and location of the deceased's blood spray, and I can basically determine that the deceased was attacked and killed by a knife from behind. Also, I speculate that the killer sneaked into the apartment through the window and waited for the opportunity to kill the deceased, and then escaped through the window. Our team's trace experts have conducted a detailed survey of the windows and window railings of the apartment, and found several white fibers on both sides of the window sill in an almost symmetrical position, some brown fibers on the right side, and blue fibers in the middle and upper part of the window sill. Yan Xiu analyzed seriously, and then paused and looked at Li Chengfeng suspiciously: "But what I don't understand is that judging from the situation of the apartment, the deceased should have moved to live somewhere else, why did he come back here?" ”

"Thank you, Captain Yan, I appreciate your kindness, but this involves the large-scale homicide case of the Wei family that we are investigating, because the case has not yet been solved, it is not convenient to disclose it for the time being, I hope you understand." Li Chengfeng said.

"Okay, then I won't embarrass Captain Li." Yan Xiu said regretfully.

"Team Lee." The voices of Yang Peiwu and You Jun came from outside the door.

"It seems that your people have already come, then I will leave first, and I will inform Captain Li as soon as the results of the experiment come out." After Yan Xiu finished speaking, he led his people outside, but stopped when he walked to Fang Xinling's side.

"Why are you here?" Yan Xiu's voice was low.

"It's none of your business." Fang Xinling tilted his head and stopped looking at him.

Yan Xiu sighed in a low voice and left.

Next, the people from the big case squadron of the Liancheng Branch began to take over the scene, and after Yang Peiwu and You Jun and others came to the scene, they first greeted Li Chengfeng and the three of them, and began to work. An hour later, Li Chengfeng found that the results of their investigation were basically the same as Yan Xiu's theory, and no more clues were found.

"Fang Xinling, have you found anything?" Li Chengfeng saw the absent-minded Fang Xinling and couldn't help but ask.

"Nope." Fang Xinling shook his head.

After that, Li Chengfeng asked You Jun to check the monitoring of the Minglai community, but there was nothing to gain. The current security system of Minglai community is basically in a state of obsolescence, and the monitoring has been out of service for a long time. So they simply processed and recorded the scene and planned to return to the team.

When Fang Xinling and Su Xiaonan went downstairs, she noticed Yan Xiu standing not far away.
