Chapter 4 Expanding the Investigation

  While Liu Li was deep in thought, Captain Zhang Yuqing walked to the side of the body and looked at the movements of Liu Li and others. He turned his gaze to Li Liang: "Have you finished examining the body?"

  Li Liang nodded and then spoke out his preliminary inspection results. After listening to Li Liang's results, Zhang Yuqing squatted down to take a closer look at the body, then stood up and instructed:

  "First, transport the body to the hospital morgue, then contact the deceased's family and try to persuade them to agree to an autopsy. The cause of death must be thoroughly verified and cannot be speculated based on experience."

  "After going back, send people to visit and investigate the social relationships and interpersonal circles of the deceased, see if the deceased had any grudges with anyone during this period? Check if the deceased had any abnormal behavior recently?"

  After instructing, Zhang Yuqing glanced at Liu Li and said in a cold tone: "We've taken over this case, you can go back now. If you're free, you can help find some clues from the outside, don't just wander around here looking for shoe prints."

  "If the murderer was really a ghost, there would be no footprints left here. If the murderer's intention was to deliberately kill the victim, then there would also be no footprints left here, because the murderer would have erased his own traces."

  After saying that, Zhang Yuqing instructed others to start handling the bodies. Seeing the disdain in Zhang Yuqing's words, Liu Li couldn't help but mutter to himself: "Alas... a phoenix fallen to the ground is indeed not as good as a chicken. In the past, who would dare speak to me like this?"

  "Liu Ge, what are you muttering about? Zhang Du has already taken over the case, let's go back, this is none of our business." At this time, Dou Zhihao's voice came over.

  "Go back? Go where? This case was the first to be handled by me, and it will also be solved by me." After saying this, Liu Li looked at the tombstone next to the corpse, then looked at the deceased again.

  Then he took advantage of the fact that no one was paying attention, and quietly took a few photos of the deceased with his mobile phone. Next, he quietly instructed Dou Zhihao: "Brother, you come over tomorrow to investigate the shoe prints here, categorize each shoe print and mark them clearly. Also, take some extra trouble to record the number of each type of shoe print."

  Then you investigate the hanging suicide of Wang Jie, check out Wang Jie's social circle before her death, and the reason for her hanging suicide, see if there was any intersection between Wang Jie and the deceased before her death.

  "Brother, do you still want to investigate? Didn't Captain Zhang already assign someone to look into the case? The criminal police team has taken over, if we intervene and Captain Zhang finds out, it won't be good. Besides, this might really be a vengeful spirit killing people! The Ghost Festival is coming up soon, let's not get involved in this, it's unlucky." Dou Zhihao asked quietly.

  "What nonsense, are you kidding me? There's no such thing as ghosts in this world! You're still so young, how can you be so superstitious? Brother, your current identity is still a auxiliary police officer, right? Want to become a regular police officer? If you do, then listen to big brother's words and behave yourself. After the case is solved, big brother will at least help you get an official position."

  At this point, Liu Li cautiously glanced around and saw that Zhang Yuqing and others did not notice him, so he lowered his voice and said: "If I didn't judge wrong, the direction of Zhang Yuqing's investigation is incorrect. If we follow his thinking to investigate, we may end up coming back in the end."

  Doubi Hao heard that Liu Li was able to turn his work relationship into a career, and without hesitation, he executed the command. He watched as Doubi Hao went to register Wang Jie's information on the tombstone, while Liu Li walked towards the deceased's electric vehicle location.

  He glanced at the electric vehicle lying on the ground, Liu Li stood up three electric vehicles one by one. At this time, he saw that one of the electric vehicles had a flat tire. Needless to say, this electric vehicle was Du Yan's.

  After a closer inspection of the tire, Liu Li found that there was a thin iron wire about five centimeters long stuck in the tire. It was because of this thin iron wire that Du Yan's tire went flat. After pulling out the thin iron wire stuck in the tire, Liu Li shone his flashlight and bent down to examine the ground.

  After a while, Liu Li found several similar iron wires on the ground again. In addition to these iron wires, some glass fragments on the ground were also carefully picked up by Liu Li. After finishing this, Liu Li left here.

  They didn't finish until after 7 am, when Liu Li and his team returned to the police station, while Zhang Yuqing took the criminal police officers back to their barracks. Before leaving, Zhang Yuqing asked Zhao Fei to assign two police officers to guard the crime scene, waiting for the technical department to collect evidence before lifting the cordon.

  After returning to the office, Liu Li and Dou Zhihao took a nap for more than two hours. By around 9:00 am, they began to take separate actions. Dou Zhihao volunteered to go to the scene of the murder case, while Liu Li rushed to the physical evidence collection room to study the iron wires and broken glass.

  At around 5 pm, Dou Zhihao returned to the police station and found Liu Li. Dou Zhihao reported to him: "Brother Liu, I've finished investigating the shoe prints at the murder scene. There are a total of eleven people's shoe prints at the scene, including those of Zhang Que's five men, yours, mine, Zhao Suo's, and Du Yan's three men."

  Zhang and the others, five people in total, each left over a hundred footprints at the scene. The two of us had around 160 footprints, Zhao Suo had 73 footprints, Du Yan had around 340 footprints, Peng Fei had over 290 footprints, while the deceased Lin Na had as many as 920 footprints.

  The reason for such a big difference, in my analysis, is that at the time Du Yan and Peng Fei were all hiding, so there were fewer footprints left behind. The deceased Lin Na was stared at by the murderer and couldn't hide, so she had to desperately run around everywhere, leaving many footprints.

  In addition, I investigated Wang Jie's social circle before her death. Wang Jie, female, 24 years old, from Huangcai Township Guojia Village, worked with the deceased and Du Yan at the same company before her death, and they were also roommates in the dormitory.

  Wang Jie has a good reputation and is very kind, but she is introverted and not good at socializing, so she doesn't have many friends. She only has two close friends who can talk to her heart, one is Du Yan, the other is the deceased Lin Na.

  As for Wang Jie's hanging herself, it sounds a bit like an emotional TV drama. That thing had something to do with Lin Na. At that time, Wang Jie was dating a boyfriend named Tan Shuai, who looked quite good and was very handsome and sunny.

  At first, Tan Shuai was introduced to Du Yan by someone else, but when Wang Jie and Lin Na accompanied Du Yan on a blind date, Tan Shuai took a liking to Wang Jie instead, abandoning Du Yan and choosing to pursue a romance with Wang Jie.

  The two of them have been in a romantic relationship for over a year and have also met each other's parents, they are now at the stage where they are about to get engaged.

  But for some reason? A month ago, Tan Shuai suddenly left without saying goodbye and went to work outside alone. His mobile phone was turned off and no one could contact him.

  Later, Wang Jie learned from Du Yan that at the time of the blind date, Tan Shuai had taken a liking to Wang Jie, but Lin Na, who was also present on the blind date, had fallen in love with Tan Shuai at first sight and had tried several times to steal his affections, but never had the opportunity.

  Just a few days ago, Nina went to dinner with Tan Shuai. Taking advantage of Tan Shuai's intoxication, she took him to a hotel and had an affair with him. The next day, after Tan Shuai sobered up, Nina demanded that he break up with Wang Jie.

  Tan Shuai saw that something had happened and didn't know what to do for the time being. So he left without saying goodbye, leaving here. Before leaving, Tan Shuai told Du Yan everything and asked Du Yan to find an opportunity to speak well of him.

  Du Yan chose a time to tell Wang Jie everything, but no one expected that when Wang Jie learned that her good sister had done such a thing with her fiancé, she suddenly couldn't think straight and hanged herself in her dormitory.

  After listening to Dou Zhihao's investigation, Liu Li thought for a moment and then his eyes lit up. He whispered: "You secretly keep an eye on Du Yan, see if anyone approaches her, pay attention, don't let anyone discover that you're tailing her."

  "What? Liu Ge, you suspect that Du Yan is suspicious? The murderer can't be her, right?" Dou Zhihao was somewhat surprised.

  After hearing this, Liu Li did not answer Dou Zhihao's question, but instead continued to bow his head and busy himself with the previous work. In front of him, there was a small pile of broken glass, as well as a flat-bottomed water cup made by bonding glass fragments together.

  The water glass is not yet fully bonded, with a large gap still on the surface. At this time, Liu Li is facing the magnifying glass, using tweezers to pick up a piece of broken glass and compare it with the gap in the cup for bonding.
