"Team Fu, the investigation is clear. It was indeed Wen Xiu who inadvertently revealed the movements of Hu Yuanyi's family to Jin Cuizhu, and Jin Cuizhu told Yang Yutang in turn. ”

"Why did Jin Cuizhu tell Yang Yutang?"

Jin Cuizhu didn't mean to tell Yang Yutang, she just wanted to talk about Yang Yutang on demand. ”

The next day, Sunday morning, at 8 a.m., everyone returned to the Crime Unit office on time. And listen to Xiao Hua's findings about Wen Xiu and Jin Cuizhu.

According to Wen Xiu, after learning what happened to her sister's family, she deliberately chatted with Jin Cuizhu. Although he didn't ask explicitly, did he inadvertently reveal the whereabouts of his sister's family at the last party? But Wen Xiu, who has a heart, still cleverly set out Jin Cuizhu's truth.

During this period, Jin Cuizhu told Wen Xiu that Yang Yutang had promised to arrange for her to travel recently, but Yang Yutang suddenly had an accident and then stopped it.

So Wen Xiu asked Jin Cuizhu why Yang Yutang agreed to arrange for her to travel, and Jin Cuizhu's answer was that the last time she was with Yang Yutang, she deliberately lied that Wen Xiu was going to travel with her sister's family. So Yang Yutang, who was obedient and obedient, understood what Jin Cuizhu meant, and immediately promised to arrange for her to go out to play after a while. ”

In this way, Yang Yutang does know the movements of Hu Yuanyi's family. It's just that, according to Rong Liang's investigation, the person who called for takeaway was definitely not Yang Yutang himself. ”

That is to say, there was indeed a third person at the scene of Yang Wenjing's killing. ”

Taking Xun Jianguo's words, Jia Wei said: "So can we speculate that Yang Yutang is the murderer of Yang Wenjing." And the process of committing the crime is like this: Yang Yutang, who has been secretly keeping an eye on Yang Wenjing's whereabouts, accidentally learned the whereabouts of Hu Yuanyi's family, and found that Yang Wenjing was staying at Hu Yuanyi's house. The opportunity was rare, so he sneaked to the Jinghua community in the middle of the night and successfully knocked on the door of Hu Yuan's IKEA with a fake identity. It's just that when Yang Yutang arrived, the person who had a tryst with Yang Wenjing and had sex, that is, the person who ordered takeout for Yang Wenjing, had already left Hu Yuan's IKEA. Therefore, Yang Yutang took the opportunity to kill Yang Wenjing. ”

According to the forensic examination, Yang Wenjing should have died about three hours after dinner. And the time when the person who ordered the takeaway got the dinner brought to Yang Wenjing from the cold drink stall was around half past eight in the evening. If Yang Wenjing had eaten between 9 and 10 a.m., the time of her death would have been between midnight and 1 a.m.

Judging from the time, it is in line with the time when the suspect vehicle appeared at the Rainbow Bridge. Naturally, it is also in line with the time when Cai Minru's secretly used vehicle appeared in the Triangle Garden. ”

After listening to Jia Wei and Rong Liang's analysis and inference, Fu Yuan immediately asked: "If it is really as you analyzed, then how to explain that the person who had a relationship with Yang Wenjing should clean up the used condoms, including the traces left by individuals?"

"What if the condom was flushed down the toilet by the person, and the killer cleaned up the first trace of the scene, and then inadvertently cleaned up the traces left by the former?"

"Well, that makes sense. Xun Jianguo, who agreed with Xiao Hua's analysis, then retorted: "The murder scene is obviously in the living room, why has the bathroom also been thoroughly cleaned?"

Speaking of this, Xun Jianguo suddenly remembered one thing, that is, the one that Jia Wei found from under the toilet tank in Hu Yuan's bathroom at that time had another dirt left, and it was obviously used sanitary napkins.

"By the way, the dirt of that sanitary napkin, has the technical department analyzed the results?"

"Nope. Jia Wei immediately replied: "I also asked yesterday, and said that the other dirt on it did not come from any tissue on the human body. ”

"What's that?"

"According to the laboratory analysis of the technical department, it is very likely that it is a highly volatile chemical reagent, which somehow got on the used sanitary napkin, thus contaminating some dust. ”

The more he talked, the more mysterious it became, Xun Jianguo frowned and asked, "Can't you accurately analyze what kind of chemical reagent it is?"

"The people in the technical department said that there was nothing left on it, so it was basically impossible. ”

"Then don't stay in the technical department anymore, just take it to Hu Yuanyi and her mother to identify if they inadvertently left it. ”

As he spoke, Fu Yuan's gaze fell on Xiao Hua, and Xiao Hua nodded when he heard this.

"Now that Yang Yutang is dead, the key to solving the murder of Yang Wenjing can only be to find the person who brought Yang Wenjing takeaway as soon as possible. ”

There is also the encrypted folder in Yang Wenjing's laptop, as well as the origin of the sky-high price puppet. ”

As soon as Fu Yuan's voice fell, Song Jin added in time.

"The tattoo case was stuck there because of Yang Yutang's death, and the murder of Yang Wenjing was also affected by Yang Yutang's death. Therefore, everyone has to redouble their efforts in the future. ”

"It's not that I don't work hard, I always feel like I have nowhere to go. ”

Jia Wei's words can be regarded as pouring out everyone's common thoughts, Fu Yuan nodded after hearing it and said: "The origin of the sky-high doll found in Yang Wenjing's bedroom has been learned from Vice Mayor Yang, and it was a birthday gift from Yang Wenjing's classmates when she celebrated her birthday at the beginning of the year.

Of course, this is just Yang Wenjing's words. And we are absolutely sure that this must be Yang Wenjing's lie to her parents. Because, it is impossible for a classmate to give, or be able to give, such an expensive gift.

Therefore, Song Jin and Qi Zhibin went all out to investigate where Yang Wenjing got the puppet. and what are the friends of the opposite sex who are closer to her, focusing on the older group of people. ”

At this point, Fu Yuan no longer cared about the task that Song Jin and Zhao Zengyuan came to investigate Yang Yutang's interpersonal relationship, and the personnel at hand were too nervous.

"Yes. Song Jin didn't say a word, and nodded and agreed at the same time as Qi Zhibin.

Rong Liang continued to track down the person who ordered the takeaway, and he must be found. ”

"I'm going to go to the video team of the technical department and help them watch the video together. ”

After speaking, Rong Liang stood up and left.

Qi Zhibin and Song Jin glanced at each other, and also got up and left the office.

Xiao Hua first went to the Hu family's mother and daughter to identify the dirt on the sanitary napkin, and then continued to follow the tattoo case. It is necessary to transfer manpower directly from the criminal police team of the city bureau and the grassroots police station. Ma Bureau and Political Commissar Sun personally promised to ask people to give people and things to things. ”

"Okay. Xiao Hua also left.

"Zeng Yuan and Jia Wei, continue your previous work. The first is the origin of Yang Yutang's first pot of gold, and the second is to check whether he can have intersections with Vice Mayor Yang or President Luo in his work and life. ”

Seeing Jia Wei and Zhao Zengyuan leaving, Fu Yuan said to Xun Jianguo: "Let's go investigate Yang Yutang's kinship." Although others are dead, the problem left to us is not the slightest. Moreover, if Yang Wenjing was really killed by Yang Yutang, then it is necessary to understand his motive for committing the crime. ”

The motive for the crime, the process of the crime, the murder weapon, the first, second, and even the third scene, as well as means of transportation or transportation, eyewitnesses, traces and physical evidence, etc., are all indispensable links in the complete evidence chain no matter what the case is.
