After the two re-investigated the No. 2 lighthouse, there was still no clue. Song Jiaer was busy sweating, but she didn't get any results. "Han Xu, do you think we are doing useless work?" Han Xu was a little discouraged when he heard Song Jiaer's complaint. He went to two crime scenes in a row and found nothing. Although it was a re-investigation, it still made the two elites of the Yancheng police feel discouraged. At least there was a drop of blood sample left at the No. 3 lighthouse. There was nothing at the No. 1 and No. 2 lighthouses. Xizhi's work has actually been done very well. It can only be said that the suspect is cunning enough. Without any clues, Han Xu took Song Jiaer to meet the reporter of the No. 2 lighthouse. As shown in the information, the reporter of the No. 2 lighthouse has been working in the scenic area for more than ten years.
After Han Xu's detailed questioning, it was confirmed that what the reporter said was true. Moreover, Xizhi had already investigated the reporter and there was no time to commit the crime on that day. There are many people who can testify. So far, there has been no breakthrough in the case, and it is still spinning in the same place. However, Han Xu was not panicked and still maintained a good professional quality. Song Jiaer followed for a long time, and she had done everything she should do, and it seemed that she could no longer help Han Xu. "Sorry, it seems that our trace inspection can't help much in these cases." Han Xu comforted her a few words and asked casually, "Who is the reporter of the case in our northern suburbs?" Song Jiaer smiled, "When did you remember to ask this?" Han Xu smiled awkwardly, "I am used to sorting out the case in order." "The reporter of the third case is one of our own. There were two lighthouse murders in Xizhi, so the police stations checked all the lighthouses in their jurisdiction, and found the third victim." Han Xu listened and nodded, "No wonder, the third case was discovered so timely." "Now we have walked through the crime scene, do you have any ideas?" Song Jiaer always felt that Han Xu should have had a clue. Han Xu wanted to keep it a secret, not to mention that he didn't have any evidence. So, he spread his shoulders and said, "As you can see, nothing has been found. I don't even know if the suspect is a man, a woman, one, two, or three?" "Nothing is right!" Song Jiaer pretended to be angry and ignored someone. It was already 3:30 in the afternoon when the two came out of the scenic area. The salty and humid sea breeze blew on their bodies, making them feel indescribably uncomfortable. It was already autumn, and it had been raining for several days in a row. The coolness was visible to the naked eye. Han Xu saw Song Jiaer tighten her clothes, subconsciously took off his coat and put it on her.
Song Jiaer did not refuse, but glared at someone, as if to ask what she had done earlier. Han Xu couldn't help but smile. "Where are we going now?" Song Jiaer asked. Han Xu curled his lips, "Let's go back to the police station, and see if Li Le has found anything." ... When the two drove back to the police station, Lao Zhang was still staring at the computer screen without even raising his head. "What? Did you find anything?" Hearing Lao Zhang's eyes and ears on all sides, Han Xu said helplessly, "I didn't find anything. I ran for a whole day in vain." Lao Zhang smiled and said, "That's too normal. I've been watching the surveillance for two days, let alone the suspect, I didn't even see a hair." Han Xu came over and found that Lao Zhang had been watching the surveillance outside the scenic area. He couldn't help but say, "Brother Zhang, aren't you also doing useless work?" "Who said it wasn't? But do you have evidence to prove that the murderer took the water route?" Han Xu was speechless when he heard this, "No." "That's it. Since there is no evidence to prove that the murderer took the water route, the surveillance must be checked all the time." Han Xu understood the truth of what Lao Zhang said, but he couldn't help feeling a little discouraged because he hadn't found anything in the past two days. As soon as Han Xu came in, Lao Zhang could tell that he was in low spirits, so he just tried to cheer him up in different ways. Even if many tasks are known to be useless, someone still has to do them, right? Song Jiaer sighed, said hello to Lao Zhang, and returned to the trace inspection department. Lao Zhang saw Song Jiaer leave, and then asked, "Next, how do you plan to investigate?" Han Xu paused and replied, "I think all three cases are strange, but they are all internally connected. I'm still going to start with the first case. After all, the first victim, Liu Lisha, is a local, and it should be easier to investigate than Gong Li and the third victim." "That's right, there will be more clues. Okay, you continue to be busy, and I'll continue to watch my surveillance." Lao Zhang pointed out the direction for Han Xu and prepared to disappear again. Han Xu knew Lao Zhang's intention very well. As the saying goes, an old man in the family is like a treasure! Every time he talked with Lao Zhang, Han Xu benefited a lot. At least he was no longer confused. Just at this time, Chengzi and Xiao Xiao came back from Xizhi. Chengzi saw the strange atmosphere in the office area and almost thought there was a major breakthrough. "What's going on? Your expressions are not right! Did you find something?" Han Xu shrugged helplessly, "Sorry, I ran around all day today and found nothing!" "Then why do you look so happy?" Chengzi completely ignored the point.
Xiao Xiao couldn't stand it anymore, "Okay, you haven't found anything, can't you be happy? You look so depressed, you don't look like a criminal investigator." When Han Xu saw Xiao Xiao talking, he couldn't help but ask, "Xiao Xiao, have you gained anything over there?" Xiao Xiao sorted out her thoughts and then said slowly, "There are a lot of doubts. I feel that the modus operandi of the three cases is not the same." "Oh, tell me more." Xiao Xiao continued, "I looked a little strange at the wounds in the photos before, so I went to Xizhi. The wound on the victim's back in the first case was very deep, but in the second case it was very shallow. Of course, It’s all relative. However, the obvious difference in the third case is that it is much more brutal than the previous two cases, not only in terms of quantity, but also in terms of depth.” Cheng Zi wondered, "How is this possible? If the three cases involve the same murderer, the intensity control when applying the knife should not be much different." "Not only that, I observed the shape and depth of the wound, and I could roughly deduce what kind of murder weapon was used. The result was even more strange. I was sure that the suspect did not use the same knife! So the shape of the wound was completely different. " Lao Zhang immediately grasped the key point, "So, there is another hidden secret in these three cases? Is it possible that the murderer is not the same person?" Xiao Xiao nodded, "That's what I guessed, but it can be seen that the wounds in the three cases were all cut on the right hand, so there is no evidence to prove that the murderer is not the same person." After talking for a long time, it seemed that he had come back again. "Oh, by the way, there is another question that is also very strange. The strangulation marks on the necks of Victim No. 1 and Victim No. 2 are made of the same material and are obviously different from those of Victim No. 3."
