As for Han Xu, the two did not go directly to the residence of the first victim, Liu Lisha, but took a long detour and went to Xizhi Police Station first. Because there was a possibility of merging the cases, they planned to contact Xizhi. It was also a greeting. Avoid unnecessary misunderstandings and embarrassment. Chengzi drove all the way and arrived at Xizhi Police Station not long after. In theory, the police station in the west would not be facing the sea. However, the entire terrain of Yancheng is extremely unique, belonging to the peninsula type. Not only the east and south city, but even the north suburbs and Xizhi are partly facing the sea, and the coastline is amazingly long. That's why the criminal suspects have enough space to shoot a shot in the east and a shot in the west. On the way, Han Xu had communicated with the Xizhi Police Station. They were received by Liu Ziwei, the head of the serious case team.
They were all acquaintances, so Han Xu naturally didn't say so much. After arriving at the criminal investigation reception room, he stated his purpose straight away. In fact, it was not Liu Ziwei who was in charge of the previous two cases. Instead, it was caught directly by Yu Tianfang, the great slacker in Xizhi. At this time, Liu Ziwei had long lost the arrogance he had when they first met. Seeing Han Xu coming, he served tea and water as if he were an old friend, and was very attentive. Even Chengzi was surprised. So, was he defeated? Liu Ziwei was busy for a long time before he got to the point. "In fact, most of the information in the previous two cases has been uploaded to the server. Now we don't have any particularly important clues on hand." Han Xu certainly didn't think that Xizhi would miss anything. Instead, he said, "We have already seen the case information you uploaded and shared it. There is nothing missing." Liu Ziwei smiled and said, "I didn't expect you to come here. Did you find any clues there?" Han Xu didn't hide it either, and told about the dripping bloodstains extracted from Song Jiaer at the scene. Liu Ziwei heard this and said, "That drop of blood is likely to be left by the suspect." Han Xu nodded, "On the way here, the trace inspection department has called me. After testing, the bloodstains were confirmed not to be from the victim." Hearing this information, the worry on Liu Ziwei's face finally dissipated a little. "The three cases, whether from the method of committing the crime, the target of the crime, or even the location of the crime, have internal connections. Can we apply for a joint investigation?" Han Xu nodded and said, "Yes, we came here mainly to connect with you." "Okay, I'll notify Captain Yu right away, you sit for a while." "No, we plan to go to Liu Lisha's residence." "I'll go with you?" Liu Ziwei said when he saw this. "Don't bother Team Leader Liu, we're just going to take a look around." Han Xu said very tactfully, declining Liu Ziwei's kindness.
Liu Ziwei shook his head helplessly, "Okay, if you find anything, please communicate in time." Han Xu smiled heartily, "Of course!" However, when Liu Ziwei saw Han Xu's big hand stretched out, he instantly became timid. He was stunned for a long time and didn't dare to shake it at all! ... After coming out of Xizhi Police Station, Han Xu's slightly frowned brows gradually relaxed. In fact, the three cases were quite difficult, otherwise Xizhi Yu Tianfang would not have investigated for so long without any results. You know, Mo Yu Dasheng's ability to solve cases is firmly ranked in the top two in Yancheng. It can be seen how difficult the case is. However, the contact with Xizhi was very smooth, which dispelled some of Han Xu's concerns. Next, he can focus all his energy on the case. Chengzi started the car and looked at Han Xu. "Let's go to where Liu Lisha lives." Chengzi nodded, stepped on the accelerator, and the car sped away. Victim No. 1, Liu Lisha, is single and lives alone. She rents a house in Xingfuli Community, not far from Yancheng No. 3 Middle School. This is a single apartment with poor conditions. It is small in size but very cozy. At a glance, all the furnishings are in sight. Chengzi changed her shoe covers while wondering, "Isn't it said that Liu Lisha is a teacher in No. 3 Middle School? The living conditions are too poor." Han Xu noticed it as soon as he entered the door and said casually, "Maybe she is frugal." Chengzi did not comment, "I guess it's to save money to buy a house." "It's possible," Han Xu didn't understand why many people insist on having a house of their own, maybe because of a sense of security. The two carefully re-investigated it, and indeed there was nothing to gain. If there were any clues, they must have been taken away by Xizhi. Han Xu had to take Chengzi out of the community, and then stood on the curb of the main road, centered on Xingfuli, and looked at the surrounding environment. Logically speaking, the first case is more likely to be a random crime. In other words, the suspect is likely to have acted on impulse. So, where did he target the number one victim, Liu Lisha? Xingfuli Community is only four stops away from Yancheng No. 3 Middle School. In fact, it is not too far.
The evening self-study at Yancheng No. 3 Middle School is divided into two periods, and the second period ends at 21:20, which means that the victim Liu Lisha was kidnapped after 9:30 pm. Judging from the living environment, Liu Lisha was not only frugal during her lifetime, but also to a degree that ordinary people could not understand. Han Xu saw a lot of DIY products made from waste there. So he inferred that the victim Liu Lisha might not like to take the bus in order to save money. However, the investigation results from Xizhi showed that some students saw Liu Lisha leaving by bus that night. There were four stops in total, about 2,000 meters. If Liu Lisha took the bus, where did the murderer start? The two stops for getting on and off the bus were very close to the school and the entrance of the community, so the murderer had almost no chance. Then the answer was obvious, Liu Lisha got off the bus halfway! Thinking of this, Han Xu prepared to start from Xingfuli Community. He went against Liu Lisha's route that night and walked towards Yancheng No. 3 Middle School. This section of the journey was not a straight line, but turned several intersections. After walking a few hundred meters, Han Xu suddenly found a relatively hidden alley next to a bus stop. "Hey, is that a shortcut?" Orange understood what Han Xu was doing, followed quietly, and asked in confusion when he reached the entrance of the alley. Han Xu, who is usually a road idiot, was unusually clear-headed when handling the case. He nodded and said, "From the direction, it should be!" "Then do you think that Lisa Liu was kidnapped here?" Han Xu heard Chengzi's question and stopped to look at the surrounding environment. The alley in front of him looked more like the back alley of the hotel next door. The road surface had not been maintained for some years and was uneven. There were two oversized trash cans not far away, like doormen, blocking half of the passage. "Xu, look what that is!"
