For the next two days, Li Jing and I wandered around the bar or singing studio near the downtown area where the body was found, hoping that the tourists would bring us clues. The Xiao team also checked the surveillance of the place where the incident occurred, and found that the murderer fainted the body with a trolley and discarded it at the place of the incident, and the murderer was wearing a mask and could not see his appearance clearly. The surveillance of the previous case was retrieved, and sure enough, the murderers were wearing masks. But one thing that makes people feel very strange is that the murderers in several cases are very different in appearance, some are very tall and strong, and some are thin and shriveled.

When we got together again, it was already the weekend, and Li Jing and I did not contact anyone who knew the deceased, and Team Xiao and Mr. Lu did not make substantial progress on the culture of the deceased's family. So when Shi Hao came, when he saw our four pairs of eyes shining at him, I could see from his expression how much pressure he was under at that time.

Shi Hao pasted the photos of the 25 victims on the whiteboard at a time: "These 25 victims do not know each other, and there is no trace of contact with each other in the communication records; There is also no intersection in consumption records, medical records, or education records. Don't doubt my companion's processing power though (he gestured to the computer at hand), just last night I discovered that the only thing they had in common was that they had both been to the same city at the same time. Shi Hao summarized the common points of these people in the materials issued, "In order to protect the environment, I use secondary paper for your information, so you don't have to care too much about what is written on the back of the paper." I took a red pen and marked the common release of several people, which has been marked with a red pen. The 25 men had visited City K four years ago for 12 days between July 30 and August 11, and while their spending records did not overlap, the only clear explanation for the mass murder was probably from their time in City K. ”

"Did you find out what happened during that time?" Li Jing asked Shi Hao.

Shi Hao glanced at the screen: "There are too many things, and there is no clear direction." ”

Team Xiao asked Mr. Lu: "Old Lu, what do you think of this?" ”

Teacher Lu was reading the information page by page, and pointed at Li Jing, realizing the meaning and letting Li Jing express his opinion.

"The 25 male deceased are the number we have now counted, and it is not ruled out that this number will increase again if we cannot find the suspect in time. So we were looking for places that could accommodate at least 50 people, and there were more men than women who cared for them. The suspect is accustomed to stripping the deceased naked when he kills someone, which can be seen as an insult to the deceased, so Shi Hao, you can check if there were any women who worked in Fengyue places during that time who called the police and were indecent assault. Without waiting for Team Xiao to ask, Li Jing directly stated his opinion.

"Did the woman in the Fengyue place call the police? No alarm records were found. Shi Hao quickly compared the records.

"Generally, women who work in such places rarely choose to call the police even if they are in danger." Team Xiao explained beside him.

Perhaps sensing my doubts, Mr. Lu then helped me explain: "This kind of woman is the most likely target of many murders, and the famous 'Green River Killer' Gary Ridgeway in the United States is very fond of targeting female workers in the 'red light district' to kill, and most of the 48 women he killed are engaged in the work of Fengyue places, and he thinks that no one will restore the life and death of women like Anxin." In fact, the public is really indifferent to the life and death of this type of worker, so they think that even if they go to the police and receive abuse, the public may not pay too much attention to them. What's more, because these workers are also involved in other issues such as drug dealing, they don't let themselves come into contact with the police. ”

"So Teacher Lu suspects that they may have come into contact with the women of the Fengyue Venue and get into trouble?" I probably summed up everyone's words in my head to come to this conclusion.

"This is just a guess for the time being, there is no overlap in the card records, and many people go to that kind of place to spend only in cash to avoid leaving traces of consumption. Four years have passed since the incident, and if the police had not been called at that time, and the local surveillance footage had been deleted, it would have been even more difficult to verify. Shi Hao, was the first person to leave K City on the 11th? Li Jing asked Shi Hao.

That's right, Wang Lei was the first to leave K City, when he went to K City on a business trip, and his accommodation and transportation expenses were paid by the company. The date of departure is August 9. Shi Hao looked at the information in his hand.

"Then help take a look at where Wang Lei has been on August 8. Maybe all the information was in his itinerary that day. ”

Shi Hao was busy checking Wang Lei's consumption records, and I asked Li Jing with a confused face: "Li Jing, why do you want to check the information of the earliest person who left?" ”

"Speculative psychology. Generally, when an emergency situation comes out, people's first reaction is to flee, so if nothing else, people will leave the accident site as soon as possible. The first person to leave is the person closest to the time of the incident, and in the case of a business trip, the last night of the trip is the most relaxed time for the person, and based on two considerations, August 8 is the most likely time. Shi Hao, have you found out what's wrong? ”

"There is no consumption display. I guess it's an office location where meetings are going on all the time. But I still think it's necessary for you to go over there, or the police over there will help you see if there are any clues from 4 years ago. Shi Hao shrugged his shoulders.

"Where did Wang Lei live at that time?"

"Guiyuan Hotel."

"Is there any place near the hotel like a bar street?" Teacher Lu suddenly spoke.

"Yes. The Guiyuan Hotel is adjacent to the famous bar street in K City, which was held on August 8 4 years ago...... Yes, a fire broke out in a bar on the bar street next to it, and 3 people died at the scene, 2 of them were registered with the police because of **, and the remaining 16 people were injured. Shi Hao turned the screen to us.

"Immediately check the casualties of the fire accident online, check where they have lived in the past few years, and if it is a dead person, check the location of their families." Team Xiao sent a mission.

"It is possible that the suspect this time did not commit the crime alone, and his helpers may be the victim's family members, or they may be his original accomplices. This accomplice may be absolutely subordinate to him for some reason, and there is a master-servant relationship between two or more people. The main suspect is supposed to have coerced his accomplices to assist him in the murder for some reason. It is possible that the former accomplice was killed by the main suspect for some reason, and the fear he created at the time is likely to make the later ones completely submit to him. So we still haven't fully met the leader of the gang, and this person is the key to these cases. Teacher Lu concluded, "Li Jing, we have to re-examine the suspect, but before we begin, I hope that you and Xiao Zhizhi will help me visit the bar street in K City, and learn some about the situation 4 years ago with the mothers there, and it is best to understand the things around the two dead girls." ”

Li Jing took a look at me, and I resigned myself to picking up my mobile phone and booking a plane ticket.
