After discovering that his daughter was gone, Yan Yuehan's parents were very nervous. They searched all the places where their daughter might go, but still couldn't find her whereabouts.

At this point, Yan Yuehan's parents were completely panicked and hurriedly reported the case to the police station in the jurisdiction.

After receiving the alarm, the comrades from the police station attached great importance to it. While contacting the command center to spread the news of searching people, they set a two-kilometer search range with Yonghe Community as the center, and urgently pursued them along various roads. At the same time, they sent people to train stations, bus stations and other places to search.

However, after searching for a while, no trace of the missing girl Yan Yuehan was found, so the police station transferred the case to the criminal police brigade and requested a more professional second squadron to take over the investigation.

"After we received the case, we urgently retrieved surveillance from the two communities and the surrounding intersections, and used all means to conduct a dragnet-style investigation of residents in the two communities. However, no residents had witnessed Yan Yuehan before he disappeared, nor had they heard someone calling for help or abnormal noises. In addition, Yan Yuehan was not seen in the road surveillance."

Li Yi said helplessly: "Then we began to concentrate on sorting out all the vehicles passing under the Yonghe Third Bridge that day. Now some of them have been checked, and some of them are still tracing them..."

After listening to Li Yi talking about all the current situation, Xiao Ran frowned and said, "Brother Li, have you used police dogs? At that time, not long before Yan Yuehan disappeared, the police dog should be able to track down the smell left by Yan Yuehan."

"Of course I used it, but the police dog kept circling around Chenhui Community and Sanqiao. Finally, he found a shoe in the grass below the bridge, which was the one that Yan Yuehan wore. So we suspected that the passing vehicle fell off when he pulled Yan Yuehan into the car, so we focused on the investigation on the car passing by under the bridge." Li Yi said.

"If it was a person who was a kidnapped on the road and dropped a shoe and didn't pick it up and took it away, it would be too inappropriate? And the direction is so obvious, would it be that the suspect deliberately threw the shoe in the grass, interfering with your thinking on handling the case?"

Li Fangfang said, "And from the corpse, the suspect has a strong sense of anti-reconnaissance. If he wants to disguise his doubts, I think it is very likely."

"Then you are inclined to say that Yan Yuehan was not being plundered by passing vehicles, but being harmed by nearby residents?" Qin Zihe asked.

Li Fangfang nodded and said, "I think there is a possibility."

Listening to Li Fangfang and others' discussion, Xiao Ran looked up and asked Li Yi again: "Brother Li, did the surveillance monitors you adjusted on the 16th? Have the surveillance monitors in the elevators in residential buildings been adjusted?"

"Yes, what we focus on is the surveillance on the 16th, and the surveillance in the next two days was also adjusted, but no abnormalities were seen. Today's surveillance was not in time."

Li Yi said: "But their elevator is broken and there is no surveillance inside."

"There is no figure on the intersection surveillance, the police dog has no clear tracking direction, there is a shoe under the bridge, the internal organs are missing, and the body appears in the river..."

Xiao Ran rubbed his fingertips and quickly passed the known information in his mind, saying, "So now there are still two possibilities: one, Yan Yuehan was kidnapped by a vehicle passing under the Three Bridges; the other, Yan Yuehan was killed by someone in the two communities."

"If Yan Yuehan was temporarily kidnapped by a person in a certain car and then killed, it would be difficult to investigate this direction. Because there is no surveillance under the bridge, and there is no sign of Yan Yuehan in a certain car. If it is a case done by the person in the car, they may not be residents of the surrounding area, and they will never return after committing the crime. Even if we can find the suspect in the future, all the traces of them will be gone after washing the car many times. They insist that they are unaware of it and want to be criminally detained. So if someone drives a car to kidnap Yan Yuehan and then commits the crime, then we must find him in the shortest time to prevent him from damaging the evidence."

Xiao Ran continued: "If Yan Yuehan was killed by residents in the community and the police dogs kept circling downstairs in the community, then the scene of the incident was either at the suspect's home or in a remote and unaware place in the community. You cannot think that Yan Yuehan has not entered a building just because the police dog has not been tracked. In my opinion, the probability of these two possibilities is equal."

"In addition, Yan Yuehan is already 14 years old. Judging from her figure, she is already a big child. If she was killed in the community, the residents nearby did not notice the abnormal noise or heard the call for help, this is abnormal."

"So I think the suspect either knew Yan Yuehan, and Yan Yuehan was not alert and thus fell into trouble; or the suspect controlled Yan Yuehan in a very short time, making her unable to make a sound."

"If it is the latter, the suspect pulls or drags it into the building from the road, and the probability of being seen is too high, which can basically be ruled out. In this way, the last chance for strangers to take the lead should be when Yan Yuehan went to find classmate Xiaofang, and was preparing or taking the elevator. Therefore, the residents of the building where Yan Yuehan's classmate Xiaofang lived should be checked again."

"Of course, if the suspect knew the girl Yan Yuehan and tricked Yan Yuehan into his home, then the focus should be on screening out residents in the two communities who are more familiar with Yan Yuehan or Yan Yuehan's family."

"The key point is to focus on men. Yan Yuehan is likely to have been infringed during her lifetime. It is not ruled out that the suspect has a fetish of pedophilia. From a psychological analysis, if such a person is an adult, he should usually look honest and upright, not talk much, have an ordinary face, and is very unattractive. The relationship between husband and wife is probably not very good."

After hearing what Xiao Ran said, Li Yi looked at Xiao Ran in admiration and said, "I heard what you said, if the suspect is really a resident of the two communities, it would be much easier. But if Yan Yuehan was really abducted by a passing vehicle, many people were running long distances, and the vehicle was unsure, and we couldn't figure out which car it was, this is the most troublesome thing."

"This is our business. It should be soon." Xiao Ran said calmly.

Although the current situation is still very complicated to Li Yi and the others, there are many things to investigate, in Xiao Ran's eyes, the conditions for handling this case are really much better than before.

Surrounding the two communities, surveillance is fully covered. Any personnel or vehicles entering and leaving the two communities will inevitably be photographed by the surveillance, and there is no section of road missing surveillance.

So with the plug-in of Eye of Justice, Xiao Ran felt that even if he only looked at the surveillance, he could screen out the suspects.

However, Xiao Ran knew it was one thing in his heart, and it was another thing to find sufficient evidence to prove that the suspect committed the crime. In this situation, Xiao Ran thought that the former was easy, but the latter would be difficult.

"Brother Li, I need all the monitoring in and out of the two communities, Yonghe and Chenhui, from the 16th to today. There are also information about all residents in these two communities, and I need to bring photos."
