Chapter 49 The murderer's escape route is determined
Han Yun picked up his phone and shone it forward, and found that there were paths in the sewer, and there were paths on both sides that could accommodate one person. However, the most critical problem here was not the difficulty of walking, but the smell.
Han Yun was about to return to the upper level when he looked up and saw a man coming down from the manhole cover. The man was wearing a gas mask and a waterproof suit. After coming down the iron ladder, he threw the mask in his hand to Han Yun and said, "You are crazy."
The person who spoke was Li Tieyun. Han Yun took the mask and put it on. He felt better and said to Li Tieyun, "Why are you here?"
"Miaomiao called and said that you ran into the sewer by yourself. Do you know that this is not a joke?" Li Tieyun severely criticized Han Yun: "You dared to come down like this without knowing the depth of the situation. I don't know whether to say that you are brave or stupid."
"The murderer should have carried the equipment when escaping, but the police checked all the road surveillance and found no suspicious people or vehicles. This proves that the murderer found a way to escape the scene and get rid of the surveillance." Han Yun said to Li Tieyun, "And this is the only escape route that the murderer can escape from the surveillance."
"Did you find anything?" Li Tieyun asked.
Han Yun shook his head, raised his hand to take the high-power flashlight from Li Tieyun's hand, turned it on and shone it in front of him, then said, "Let's go forward."
Li Tieyun snatched the flashlight and took a step forward. He stood in front of Han Yun and said, "The water depth here is not fixed. If you step on empty water, your whole body will fall down. The deepest is more than two meters. Follow me. I don't want you to investigate my case and get into any danger." After saying that, Li Tieyun moved forward tentatively, and Han Yun followed behind him.
There is more than one way through the sewer. When the two came to the first fork, Han Yun signaled Li Tieyun to go left. When they reached the corresponding manhole cover , Han Yun climbed up the iron ladder, then used his body strength to push open the manhole cover, stuck his head out and took a look, then restored the manhole cover to its original position and walked down. He shook his head and said to Li Tieyun, "Climbing up from here will face the road surveillance not far away."
"If we continue to search like this, we'll probably die before we find it." Li Tieyun took out the walkie-talkie from his waist and said to the team members above, "Call the traffic team to learn about the terrain nearby and see which sections of the road are blind spots for surveillance. "
A few seconds later, a man's voice came from the intercom: "Received."
Han Yun walked a hundred meters and was already panting. Li Tieyun had received professional training and was naturally much stronger than Han Yun, but he was also a little exhausted at this time. He cursed: "Damn it, I have been investigating cases for so many years , and this is the first time I walk in shit soup."
"The murderer must have practiced his escape route in advance. Otherwise, how could he have determined where the water was deep and shallow? And escaped successfully..." Han Yun used the flashlight on his phone to look around, then pointed to a place not far away and said, "What is that?"
Li Tieyun shone his flashlight over there and said, "It looks like... a gas mask?"
The two of them walked over at once. Han Yun grabbed the mask floating on the water, took a look, and then handed it to Li Tieyun: "Maybe the murderer threw it here. The water flow in the sewer is not fast. If there is no external force to help, the mask will not float far after being thrown. So the murderer must have climbed up along the manhole cover nearby."
"The trip was not in vain, we still gained something." Li Tieyun also agreed with what Han Yun said.
As soon as he finished speaking, the intercom rang, and the team member on it said, "I asked the traffic team and checked the city map. There is a manhole cover in the community. There are surveillance cameras in the vicinity except for the main entrance of the community and the garage, but the location of the manhole cover is a blind spot for surveillance. I asked Yu Miaomiao to send the location to Detective Han's phone."
After hearing this, Han Yun opened WeChat on his phone, found the WeChat message from Yu Miaomiao, clicked on the map, and then showed it to Li Tieyun. The two walked forward a distance according to the map, and came to the bottom of the manhole cover shown. Han Yun climbed up first and pushed open the manhole cover. This was indeed the interior of the community. He shouted to Li Tieyun below, "It should be here." Then he climbed up.
Li Tieyun followed, and the two took off their gas masks, greedily took a few gulps of fresh air, and then looked around. This was a corner of the community, and judging from the stairs, the community should be quite old. If the murderer came out after midnight, it would be difficult to be discovered unless someone sat by the window and stared at this place all night.
"Come over here." Li Tieyun said into the intercom while taking off his waterproof suit, "And find a set of clothes for Detective Han."
Han Yun was soaked from the waist down, but he ignored it and quickly took a look around the neighborhood. He then said, "Even if the murderer came out from here, he would still be caught by surveillance if he wanted to leave the neighborhood that night. So do you think the murderer could have found a temporary residence in this neighborhood, escaped from the manhole cover, and returned directly to his residence?"
"That's easy. I'll send people to investigate door to door and I'll always be able to find the murderer." Li Tieyun threw away his waterproof suit and mask, and then said, "But the murderer fled to the neighborhood where he lives. This doesn't seem to be a smart move. It's not difficult to avoid the blind spots of surveillance and then escape. Look over there, although it's blocked, it's easy to climb over. "
"We only found a gas mask in the sewer, which shows that the murderer is likely to be like me, wearing a mask but not a waterproof coat. In this case, if I run away directly, will it be too conspicuous?" Han Yun asked Li Tieyun to look at him now, and then said: "The murderer knew that we would not find this place so quickly, so he had enough time to take a shower, change clothes, and then check out and leave. Even if he rented a house, the murderer would not be stupid enough to use his own identity information."
After Han Yun finished speaking, a police car drove in from the main gate of the community. Yu Miaomiao and another police officer got out of the car. After the police officer came over, he covered his nose with his hand and said directly to Han Yun: "There is a set of clothes in the back seat of the police car. Go change into it." After that, the police officer looked at Team Leader Li and said with a stifling smile: "Team Leader Li, you are really mighty this time. Really, I have followed you for almost two years, and I have never seen you so mighty."
"Stop talking nonsense." Li Tieyun glanced at the police officer, then took a deep breath and said, "Hurry up and organize police forces to check this community, and then find someone to enter the sewer to conduct a comprehensive salvage to see if the murderer has left any clues."
Han Yun walked to the police car, opened the door and sat in it. He took off his own clothes and changed into the clothes prepared by the police. Although they were a little big, they were much better than his own. It was already getting dark, and there were dark clouds in the sky. It seemed that it would rain tonight. After getting out of the police car, Han Yun walked over and asked Li Tieyun: "By the way, have you pieced together the torn photos found in Feng Qiaoqiao's room yesterday?"
