Although the video team has screened out 11 vehicles with anomalies in the time of passing through the Linglong Bridge, it will be an extremely heavy task to track the trajectory of 11 vehicles within a week if the suspect's body dumping time is not further determined, so as to narrow down the scope of investigation.

Therefore, Ling Zhan and Xun Jianguo drove to the bank of the Qingxu River again and found the location of the large black suitcase containing the victim's limbs and only missing her hands.

According to visual inspection, it is about 500 meters from the Linglong Bridge to the location where the suitcase was found. Winter is the dry season, and the river does not flow fast. After roughly estimating the flow speed and the wind speed of the weather forecast for the last two days, Ling Zhan and Xun Jianguo could basically guess that if the suspect threw the suitcase from the Linglong Bridge, then it could be basically inferred that the suitcase should not take more than two hours to reach the shore at their feet down the river.

Even if you take into account that there is a small amount of ice in some of the bays, which may affect the speed of the suitcase drift, it will not take more than five hours at most.

According to the winter swimmers who called the police, they did not find their suitcases when they were swimming in the river the morning before. It is almost impossible to say that such a conspicuous suitcase has been neglected by so many people. In other words, if the suitcase was thrown from the Linglong Bridge, it is very likely that the suspect did it last night.

This is also in line with the initial judgment of the two - the suspect is unlikely to choose to dump the body in the daytime when there is a lot of traffic.

However, to be on the safe side, Ling Zhan extended the time by one day when he called the video team to track down the suspicious vehicle. That is, to focus on the investigation of suspicious vehicles in the last two nights. As a result, there are only three cars left.

"Uncle Xun, at present, before the rest of the victim's stumps are found, especially the hands, there is indeed only one possibility that is the best."

"Hmm. The suspect was either very familiar with the victim, or at least knew about the fact that the victim had lost the handbag and took it from the Ganqiao police station. ”

"Is there another possibility?" Ling Zhan said while driving: "Maybe the suspect is not familiar with the victim, but only learned about the victim's fingerprints collected by the police through the Ganqiao Police Station?" ”

"It really can't be ruled out."

So there are two more possibilities. One is that the suspect is someone from within us, and the other is that the suspect learned about it by picking up the victim's lost handbag and handing it over to someone at the Ganqiao police station. Even, the suspect is the person who picked up the victim's handbag. ”

"Simply, let's go directly to the Ganqiao Police Station to find out the situation."

When the two drove to the Ganqiao Police Station and found the police on duty who was handling the matter at that time, they found that the person who picked up Wang Li's lost handbag was a sanitation worker, and a simple aunt in her fifties from the countryside. Therefore, the possibility that the suspect just picked up the victim's lost handbag is basically ruled out.

Immediately, Ling Zhan and Xun Jianguo found the sanitation worker to understand the situation, and according to the other party's reaction, she was not the only one who picked up the handbag at that time, and there was also a colleague of hers. It's just that when I went to the police station, the colleague didn't go with me because he had something to do temporarily.

As for whether she mentioned it to others afterwards, the sanitation worker's aunt said that the city evening newspaper and the city TV station had reported her deeds of collecting gold, and there were many people who knew about it.

"That is, the suspect learned about this news from the relevant reports of the city evening newspaper and the city television station?"

"It's more likely, but we can't rule out the possibility that it was done by our insiders." Xun Jianguo hesitated for a moment and said: "If I remember correctly, Director Xu of the Propaganda Department was an intern at the Ganqiao Police Station when he first graduated, and then he was transferred to the City Bureau. ”

Although neither of them wanted to be influenced by subjective consciousness, which would lead to a bias in their analysis and judgment, they tried not to link the two cases. However, first Suo Jianxing committed suicide without warning, and then found out that the young female teacher Wang Li had been killed. Especially before that, Xu Qianxiang had visited Suo Jianxing's Yayi pawnshop twice in a row.

Therefore, no matter what, the two of them can't restrain themselves from thinking about the three together.

Ling Zhan came late, so he naturally didn't understand the situation. When they returned to the bureau and took out Xu Qianxiang's resume, it was the same as Xun Jianguo said, Xu Qianxiang had worked in the Ganqiao Police Station for a year and ten months. In other words, he should be extremely familiar with some of the police officers of the Ganqiao Police Station.

This doesn't mean anything, and before getting other conclusive evidence, Ling Zhan and Xun Jianguo just glanced at each other, and neither of them said anything about it. In particular, according to the current knowledge of the time when the suspect threw the body and the time when Suo Jianxing committed suicide, this point does not match at all, and the two of them cannot help but doubt the correctness of the suspicion that just arose in their hearts.

"Ling Ju, one of the three cars that appeared two nights ago and passed through the Linglong Bridge at an unusual time, looked very suspicious."

After receiving the report from the video team, the two came to the video team to watch the trajectory of the suspicious vehicle and found that the car was a black Volkswagen brand car. It was at 11:40 last night when I passed the Linglong Bridge.

Since the total length of the Linglong Bridge is 1,946 meters, and the maximum speed of the bridge is 40 kilometers, it will generally not exceed three minutes according to the normal driving speed. The black Volkswagen drove for a full eighteen minutes, and what was even stranger was that eighteen minutes later the car appeared on the camera on the side of the Linglong Bridge out of the city.

That is, the car made a U-turn after staying on the bridge for a short time.

Continuing to track the car's trajectory, it was found that it had exited in front of a bar and ended up on the Linglong Bridge. After turning around from the Linglong Bridge, I didn't drive back to the bar, but went to a residential community just across the street from the bar, less than a kilometer away. After that, it did not reappear until dawn.

In this way, it is not difficult to conclude that the residential area where the car eventually disappeared is very likely to be the foothold of the owner.

But why didn't he go back directly after leaving the bar, but went to Linglong Bridge, so that he made a circle of more than five kilometers before returning to his residence?

"Have you found the owner's information?"

"Found it. This is the detailed information of the owner of the car that has just been transmitted by the traffic police. ”

Next, Ling Zhan learned from investigating the bar and contacting the owner directly that the person was just in a bad mood for a while, and he drank a lot of alcohol alone in the bar at night, and he wanted to blow the wind on the Linglong Bridge while he was drinking. I just stood on the bridge for a while and felt bored, and then drove back home.

Ling Zhan didn't come to check for drunk driving. So he immediately communicated with his family and confirmed that what the owner said was true, so he had to return to the bureau and order the video team to continue to track the driving tracks of the remaining two suspicious vehicles.
