During the incident, more than one person saw Cai Aqi entering and leaving Li Xuemei's house, and some people saw Cai Aqi being blasted out of the door by Li Xuemei. And on the night Li Xuemei was killed, Cai Aqi claimed that a young man named Beard spent the night with him nearby, which can prove that he never left. But Hu Zi said that he drank with Cai Aqi, he couldn't drink enough, he went to bed early, slept soundly, and it was not clear whether Cai Aqi had left.

However, no conclusive evidence has been found. The most tricky thing is that Cai Aqi's fingerprints were not extracted from the wires used to bind Li Xuemei, only the fingerprints of Zhang Feng, Li Xuemei and other individuals, and the people who extracted the fingerprints have ruled out suspicion, they are all friends of Zhang Feng, who went to the basement to play mahjong and drink tea before, and moved the wires when moving items. As a result, the case has not been solved so far.

"The murderer will soon be exposed on his own." Yan Xinyi's face was determined.

"Why?" Zheng Ming and Fu Qingren asked in surprise almost at the same time.

"I won't tell you yet." Yan Xinyi sold it, "This situation is very important, I'll go back and report it immediately!" ”

Yan Xinyi hurried back to the Municipal Public Security Bureau and reported the situation to Lu Ruigang and Shi Tianlin in detail.

"Based on the so-called portrait alone, it is too hasty to conclude that Cai Aqi is the murderer of Li Xuemei, and he will expose himself." Lu Ruigang was still skeptical.

"I'm absolutely sure." Yan Xinyi is full of confidence.

Fu Qingren also went back to the city bureau with Yan Xinyi to report, he admired Yan Xinyi's previous analysis, and also helped her speak at this time: "Cai Aqi's situation is indeed very consistent with Xiao Yan's portrait. ”

"Cai Aqi killed Li Xuemei, and now a woman with a high resemblance to Li Xuemei appeared in the place where Cai Aqi's live-in girlfriend was killed. Don't you think that these two cases are inextricably linked? Yan Xinyi added, "I insist on my opinion, Zhong Kenan is not lying, he did see a woman who looks almost exactly like Li Xuemei." I think the murderer is a housewife, and that's right, the murderer is not the real Li Xuemei. So far, I haven't had any problems with my portrait. ”

Lu Ruigang frowned, "Then, let's investigate whether that woman exists." He immediately assigned the task and asked the people of the criminal police team to take Li Xuemei's photos to investigate whether anyone in and around the apartment building had seen a woman who looked like Li Xuemei during the time when Chen Lingling was killed. and whether the woman was captured by nearby surveillance cameras.

After Lu Rui just finished assigning the task, Shi Tianlin proposed: "Regardless of whether Cai Aqi is the real murderer of Li Xuemei or not, these two cases seem to be related, I think we should ask the upper authorities whether it is necessary to combine the cases for investigation." ”

Lu Rui just pondered for a moment before saying, "I'll think about it again." ”

Two days later, in the early morning, Yan Xinyi went to a small shop near the Public Security Bureau to have breakfast, and as soon as she entered the door, she saw Shen Hong waving at her, and he was dining alone. Yan Xinyi walked up to him, and he patted the empty seat beside him. "I was planning to go to you after work, I have something important."

"What's the matter?" Yan Xinyi hurriedly sat down beside him.

"You don't know, the instructions from above have been combined to investigate Cai Aqi's Internet fraud, Chen Lingling's murder, and Li Xuemei's murder half a year ago." Shen Hong couldn't wait to say.

"Really, that's great." Yan Xinyi is sincerely happy that she has contributed to this result.

"But......" Shen Hong became distracted, "I heard...... Team Lu didn't plan to let you join the task force...... He felt ...... You're going to disrupt the direction of detection......"

Before he finished speaking, Yan Xinyi stood up and rushed out of the shop, she was going to find Lu Ruigang to theorize.

Shen Hong shouted behind her, but she ran so fast that he had to hurriedly settle the bill and chase out, but Yan Xinyi was gone.

Yan Xinyi ran into an alley, found a relatively quiet place, took out her mobile phone, quickly flipped through the address book, and dialed Lu Ruigang's mobile phone. She took a deep breath, and as soon as the phone was connected, the other party had not yet spoken, and the anger she was holding back in her heart could no longer be controlled, and she poured out excitedly: "Team Lu, you are too much, why don't you let me join the task force!" Where am I disrupting the direction of the investigation? On the contrary, it was I who pointed out the direction of the investigation, and it was precisely because I believed in Zhong Kenan that I found out that Cai Aqi and Li Xuemei were related to the murder, but you didn't recognize me at all, why? ”

The other party was silent, not making a sound at all.

"Why don't you speak, your heart is empty, right?" The other party's silence stimulated her "fighting spirit" even more, "Song Jingyan said that Zhong Kenan is a stone in a pit, I think this metaphor is more suitable for you, you are an old stubborn who eats the old!" ”

"At 9 a.m., the task force meets." Lu Rui just threw out a sentence and hung up the phone.
